Description

The The present invention relates to silo devices comprising a container with a superabsorbent polymer content as well as a bracket. Furthermore, the invention relates to a transport unit and a consumer equipment comprising such a silo device. In addition, a method and method for providing superabsorbent Polymers with at least one silo device described.

When transporting or storing superabsorbent polymers, a large number of different factors must be taken into account. So far, essentially two concepts that differ greatly from each other have spread. The first concept provides a silo device which is filled at regular intervals, for example by means of a pressure conveyor. These silo devices are mostly built slim and are positioned upright. This results in a height of the container of several meters, for example more than 6 m, to a significant compression of the superabsorbent polymers due to their own weight and the prevailing gravity. Especially in connection with moisture, the phenomenon of "caking" can occur, whereby a kind of caking or agglomeration of the superabsorbent polymers takes place, which on the one hand means that the outlet is clogged or caked polymers are not included In the event of blockages, it may be necessary for the superabsorbent polymer to be loosened up or even drained off by unfavorable mechanical effects such as stirring, knocking, and also the risk of such agglomerates later on becoming the subsequent process In addition, the disintegration of agglomerates may lead to disintegration, which may lead to a change and inhomogeneity of the particle size distribution of the superabsorbent polymers disadvantageous in the manufacture of sanitary articles such as diapers, since variations in particle size distributions lead to undesirable deterioration in absorbent and absorbent characteristics, such as, inter alia EP 0 304 319 B1 evident. Already it follows that superabsorbent polymers, especially when they are present as particles, are not comparable with normal bulk materials in their properties.

The solution to the problems associated with caking is known from various approaches. So will the Caking in EP 1 105 168 A1 . US 4,734,478 and US 5,728,742 by encountering the superabsorbent polymer with inorganic powders such as silicates. DE 100 52 966 A1 uses surfactants to prevent caking. All these approaches are disadvantageous because they require the use of additives, which in turn are not without effect on properties of the superabsorbent polymer, which in turn must be compensated by further measures. Other attempts to reduce coking are by feeding dry gases into the silo device or by thermal insulation, which requires additional effort.

One Another disadvantage arises from the different types suberabsorbierender polymers for different applications over distinctly different flow properties feature, the above in addition still humidity-dependent could be. This makes it necessary that the known silo devices for different Types of superabsorbent polymers are each designed separately have to, to allow a smooth operation. This applies in particular for the Dimensions and size, material, surface and angle of the funnel area. Happens this separate interpretation not, this is silo damage, especially buckling damage by collapsing cornices or wall thickness weakenings in consequence of abrasive action, to be feared.

The second concept provides for lower staging volumes where the superabsorbent polymers are delivered and stored in so-called "big bags." The small package size means that the supply of superabsorbent polymers to industrial consumers must be interrupted over and over again as the packing units change Furthermore, it has to be taken into account that these smaller packaging units require a considerable amount of space and require a considerable amount of logistics (professional qualifications of the personnel, load conveyors, software, know-how) and the handling of big bags often results in unwanted dust generation In addition, the re-use of big bags is associated with very high costs, and for superabsorbent polymers intended for hygiene applications hardly desired by the recipients of these polymers s the contents of the oldest packing units are supplied to the subsequent process or a corresponding redistribution of new deliveries and old inventories are made. If it is not possible to maintain such logistics over a long period of time, then different qualities of the follow-up process or the outcome of it are different qualities Resulting product. In addition, there is also the danger of Cakings in the case of the Big Bags during prolonged storage, especially transported by moisture.

Besides, are off DE 71 37 391 U . DE 296 21 426 U . DE 43 03 349 C1 such as DE 44 12 680 A1 a variety of differently designed and operating containers known. However, these documents do not indicate which containers of the prior art are particularly suitable for the storage, portioning or transport of superabsorbent polymers.

It also concerns DE 195 34 948 A1 a method for condition monitoring of containers with perishable cargo on sea transport. Also, this document is no indication for storage, portioning or transport of superabsorbent polymers.

Of these, It is the object of the present invention to provide a transport, Storage or provision possibility for superabsorbent polymers be specified that a trouble-free Processing process and superabsorbent polymers containing Ensure end products of consistently high quality. Next should also A silo device can be specified that addresses the specific difficulties tuned for the treatment of superabsorbent polymers is. It should simultaneously a large container volume and a possible long-term preservation of the properties of the superabsorbent Be assured polymers. It's also about the need to Silo devices on various types of superabsorbent polymers adapt, overcome. In addition, the risk of the occurrence of damage to silo devices should be reduced. Further should also the criteria of a large-scale processing of superabsorbent polymers with the resulting aspects with regard to the provision quantity and / or speed The supervision of inventories become. Furthermore should also specify a simple way to transport such silo devices become. Subject is further, a consumer unit for superabsorbent To create polymers that are safe in operation as well a particularly efficient storage or provision of superabsorbent Distinguished polymers. In addition this is also a method for providing superabsorbent Polymers are given, which is a reliable operation of superabsorbent polymers during the transport and delivery phase ensures. After all It is also the task to specify a method which is a "just-in-time" delivery of superabsorbent Polymer towards a silo device allows. Furthermore, the occurrence should be reduced by caking.

These Tasks are solved with a silo device according to claims 1 to 12.

The Silo device according to the invention includes a container with a superabsorbent polymer content and a Holder, wherein means for generating a relative movement of container and bracket are provided.

With a "container" in particular a weatherproof container is meant also the usual weather conditions may be exposed for long periods. This could be made, therefore, of metal or a plastic. The volume of the container is preferably at least 20 m ^3, in particular in a range of 30 m ³ to 80 m ^3. In addition, it is preferred that the container has a length in the range of 3 to 15, preferably 6 to 12 m and a width and height in the range of 1.5 to 3 and preferably from 2 to 2, 8 m owns.

Of the container can over his height have a constant cross-section, but this is not mandatory required. As cross-sectional shapes are rectangles or circular cross-sections prefers.

A "holder" in this sense is preferably a metal framework, where the container, preferably solvable, is attached. The holder opens the possibility, the container to grab, put down or transport. The holder is be preferably designed so that a removal of the contents of the container is possible. At the same time, a safe stand in a remote from the ground Position of the container possible, in the stable supports or feet provided are.

The Means for generating a relative movement of the container and Holder preferably comprise movable parts of the holder and / or the container, the e.g. with regard to their orientation or angular position and / or in terms of variable in length accomplished are. The relative movement can be carried out in predetermined steps, for example, by special locking steps and / or locks to be provided. But it is also possible to have a continuous To allow relative movement in that infinitely variable movement elements are used.

The term "relative movement" serves as a generic term for a multiplicity of different types of movement, for example a rotational movement, a pivoting movement, a tilting movement, a move. This creates the possibility that the superabsorbent polymers perform a relative movement with respect to the container or with respect to the holder. In this way, the tendency to caking can be reduced to a considerable extent, although large storage or transport volumes are realized.

As superabsorbent polymers are generally all known in the art into consideration. In this connection, reference is made to Modern Superabsorbent Polymer Technology, Fl Buchholz, AT Graham, Wiley-VCH, 1998. Preferred as superabsorbent polymers are - based in each case on the superabsorbent polymer - at least 50 wt .-%, preferably at least 80 wt .-% and particularly preferably at least 95 wt .-% acrylic acid-based, slightly crosslinked, at least 50 mol% neutralized polyacrylates , Furthermore, it is preferred that superabsorbent polymers have an ERT absorption ("ERT" for EDANA recommended test and "EDANA" for European Diaper and Nonwoven Association) 442.1-99 of at least 10 g / g, preferably at least 15 g / g, and have an absorbance according to ERT 10.3-99 of at least 15 g / g and preferably 20 g / g.

Inventive superabsorbent polymers are commercially available from the company Stockhausen GmbH & Co. KG under the trade name Favor ^®.

The Means for generating a relative movement preferably include drives, Motors, controls and / or controls. The motors can be electric motors, Internal combustion engines, linear motors, or other drives be. These engines can directly or via Gearbox as well as similar Components a relative movement of the container and the holder to each other cause. To operate these motors or drives are advantageously corresponding Controls and controls provided.

According to one further embodiment of the silo device comprise the means for generating a relative movement, a pivot axis and at least a lifting device. The pivot axis describes a kind of pivot, pivoted around the container or can be tilted. The rotation of the container about this pivot axis is effected with a lifting device, which preferably on from the pivot axis remote parts of the holder is provided. That's the way it is, for example advantageous if the pivot axis provided near a front side of the container is while the lifting device near the opposite end on container attacks. The arrangement of the lifting device is in particular under consideration to make the maximum lever arm, as a long distance from the pivot bearing at such a big Containers one long stroke away requires. Preferably, the lifting device is in the Integrated bracket. That means with In other words, that the holder z. B. has two components, between which at least one variable-length Movement element is positioned. This movement element is stretched or shortened in order to effect a relative movement in this way, the two components of the brackets from each other to remove or approximate each other.

Especially it is preferred that the at least one lifting device a hydraulically operated lifting device. This hydraulic unit comprises Advantageously, an electric motor or a diesel generator, which at least one telescopic arm according to the hydraulic principle of action working driven. Preferably, such a lifting device one or two hydraulically acting telescopic arms (e).

Corresponding a development of the silo device, the holder comprises a substantially horizontal frame and the container a center axis, wherein the means for generating a relative movement a pivot angle between frame and center axis in the range to 90, preferably provide up to 60 and more preferably to 50 degrees [°]. Thus, the Holder constructed of several components, this one self-supporting, substantially horizontally oriented frame includes. The container itself may then be over individual Fasteners or another frame or frame fragments secured. The means for generating a relative movement are now preferably between these frames and the mounting units on container positioned and cause a pivoting movement.

Of the Swing angle is advantageously infinitely variable in the range of 0 ° (horizontal) up to 90 ° (vertical) adjustable, whereby the position of the container are permanently fixed can. The center axis is given as a reference characteristic, if necessary may also be another reference characteristic, such as one parallel straight line through the outer wall the container, be used. In general, it should be expressed that the means for generating a relative movement enable that the container, which, for example, first with its peripheral surface parallel to the horizontal was placed in a position can, in which the faces parallel and the peripheral surfaces are arranged perpendicular to the horizontal.

To Another embodiment of the invention comprises the holder an adapter for a transport unit. Thereafter, the holder may comprise means the one at least temporary, detachable connection or fix with a transport unit. Examples are couplings, hinges, Recordings. Adapters for floor-bound transport units are preferred such as trucks and / or rail vehicles. Of the Adapter is preferably on the opposite side of the container from the holder attached or integrated there in the holder.

one further embodiment of the silo device are means provided for controlling the relative movement. This control is used preferably for controlling drive units or movement elements to carry out the relative movement. The controller can be part of the bracket itself but it is also possible that this part of the transport unit or a separate control part is. For the latter case, it is advisable that the holder a Art interface, which provides a trouble-free coupling of the controls allows to the holder. This has the advantage that the holder can be simply constructed, and the control for each in-use bracket are connected can.

In addition, will also suggested that means for determining the degree of filling are provided. This means in other words, that means determine how much superabsorbent Polymers inside the container are located. These funds can turn be part of the bracket, but it is also possible that these agents on or in the container are provided. In particular, sensors offer, the one for the degree of filling representative, especially physical, capture value. It is also possible that an optical recognition of the degree of filling is made. With degree of filling can a Be meant variety of different characteristic characteristics for example, the height of the contents in the container, the volume of the contents based on the volume of the container, the near the outlet to the contents acting pressure. The degree of filling thus advantageously gives a current value for how much superabsorbent polymers currently inside the container yet are included.

To a development of the silo device is at least in one Area between the container and providing a protective layer to the superabsorbent polymers. Advantageously, the protective layer is arranged to be Completely prevents contact of the superabsorbent polymers with the container. The protective layer meets a variety of functions, in particular, it provides protection against contamination and moisture. This protective layer is preferably a separate component which is mounted in the interior of the container is used and for receiving the superabsorbent polymers. A such protective layer may be in the form of a sack or a foil be configured, as a moisture-repellent material Plastic offers especially. Advantageously, this protective layer has a Shape up, which is an outflow the superabsorbent polymer favors towards the outlet of the container, for example, in the dead spaces, Corners, beads, tabs, pockets are avoided. This can for example be achieved in that the protective layer designed as a bag is, wherein this has a narrowing laßkanal. The protective layer is preferably flexible and able to adhere to the contour of the container adapt. As a result, in addition to a pollution protection also the moisture content by appropriate water permeability of the protective layer to be influenced.

It It is also proposed that the silo device means for remote data transmission having. These means for remote data transmission are advantageously with the means for determining the degree of filling or the degree of Connected. This is the means for remote data transmission prefers to provide information regarding the degree of filling or other data a receiver forward. The remote data transmission can take place in all currently known ways, for example over the radio, the Internet. As a result, in particular, a level control over long distances possible. In addition to the degree of filling determining means can also be provided means for determining levels of the filling material. in this connection also come the aforementioned probes into consideration. The degree of filling or the guards performing sizes can be used for Adjustment of the swivel angle or for temporal variation of the Swivel angle like shaking of the container used to avoid caking or waxing.

According to one Another aspect of the invention is a transport unit comprising at least one silo device of the type described above proposed, wherein the at least one silo device releasably with the transport unit is connected. This detachable connection is advantageously via a Adapter provided the holder of the silo device. Come as a transport unit all currently known, for the means of transport suitable transport.

It is particularly preferred that the transport unit is a ground-based means of transport. In addition to trucks, passenger cars and rail-bound transport, such as Trains, cranes, etc. For transport itself may be made under certain circumstances changes in the holder, for example, columns are folded and / or additional components (housing, tarpaulins, scaffolding or windbreak) arranged or removed. It is also possible that previously inactive sub-components of the holder are now activated, such as wheels, brakes, lights, etc.

According to the invention will continue also a consumer facility for superabsorbent polymers comprising at least one of the above described silo devices proposed. By consumer equipment is meant in particular devices, the one treatment of the superabsorbent polymers or combine them with other components or the store superabsorbent polymers. The system can do a Comprise a plurality of different units, for example one Storage unit, a transport unit, a processing unit, a Finishing unit, one packaging unit. The silo device allows for all these units or for the consumer equipment a uniform quality of superabsorbent polymers, so that the operational safety and process reliability of the individual Units or the consumer system is significantly improved. This leads to a cost-reduced and quality-enhanced generation of various products such as hygiene articles such as diapers, incontinence products, Feminine hygiene products such as bandages or tampons, wipes.

According to one Another aspect of the invention is a method of providing of superabsorbent polymers with at least one silo device proposed, wherein the silo device comprises at least one container has superabsorbent polymers. The process is characterized that the at least one container at least during the Transport or storage of superabsorbent polymers a first position, and while the removal of superabsorbent polymers a second, from the first deviating, occupying position. In other words, that the container preferred during the removal is moved, and this continuously during the Removal or at predetermined time intervals can take place. It is also possible, the movement of the container between individual sampling processes. The transport finds preferably with a transport unit instead, as above explained has been. The while transport from the container assumed first position is advantageously also during the Storage does not change, so that the container or the contents contained therein containing superabsorbent polymers under favorable conditions can be. This results for example from a reduced Filling level or the resulting internal pressure due to the lower gravity effect across from the second position.

Especially it is advantageous that the position during removal at least temporarily changed becomes. This means in particular that the container before removal a assumes substantially horizontal position, so that the end faces of the container perpendicular aligned to the horizontal, and the position of the container now while the removal intermittently or continuously in a vertical Position is moved, with the end faces almost parallel to the horizontal are aligned so that the still located inside the container superabsorbent polymers over one near the frontal area arranged outlet can be removed. The thus removed superabsorbent Polymers can then one as a consumer system of a further processing device like a diaper, an airlaid machine or a machine for Manufacture of sanitary napkins or towels are preferred, it being preferred is that after the outlet of the silo according to the invention and before the area the post-processing device in which the superabsorbent polymer with other component of the intermediate or final product in contact comes a memory device for superabsorbent polymer is located, the maximum the volume of the container the silo according to the invention and preferably at most 50% and more preferably at most 25% as well as above In addition, preferably 10% of the volume of the container of the silo according to the invention has. In the manufacture of a diaper may be such a component for example cellulose fibers.

In addition, will also suggested that means for determining the degree of filling the current filling level determine and forward to an evaluation unit. This is the possibility a surveillance the degree of filling of the container given. For determining the degree of filling can the above funds are used. The characteristic Characteristics for describing the degree of filling are thus detected and forwarded to an evaluation. There can these values are displayed and / or further processed.

According to a particular embodiment of the method, the current filling level is compared with a limit value and, depending on the result of this comparison, a signal is transmitted to a receiver. In other words, that means that the current fill level is being evaluated. For example, this may include determining the time when the container is empty. In this case, additional parameters can be taken into account, for example, the desired outflow of superabsorbent polymers in the near future. Of the Limit may be fixed, but it is also possible that this varies depending on other parameters, such as the consumption of superabsorbent polymers. The comparison now provides information on when it is no longer possible to provide superabsorbent polymers with the silo device, when a changeover of silo devices is required, or when filled silage devices have to be requested in order to be "just-in". time ", in particular for the production taking place in continuous shift operation. To ensure this, the result is transmitted as a signal to a receiver, such as the filler of silo devices with superabsorbent polymers. The signal can be transmitted in all known technical and electronic ways, in particular using the Internet.

• – Zur Verfügung stellen wenigstens einer ersten Silo-Vorrichtung mit superabsorbierenden Polymeren;
• – Ermitteln eines Füllgrades der wenigstens einen Silo-Vorrichtung;
• – Anfordern wenigstens einer zweiten Silo-Vorrichtung mit superabsorbierenden Polymeren, so dass diese wenigstens zweite Silo-Vorrichtung spätestens dann zur Verfügung steht, wenn die wenigstens erste Silo-Vorrichtung einen Grenzwert des Füllstandes erreicht.

In addition, a method for providing polymers is proposed which comprises at least the following steps:

• Providing at least a first silo device with superabsorbent polymers;
• - Determining a degree of filling of the at least one silo device;
• Requesting at least one second silo device with superabsorbent polymers so that this at least second silo device is available at the latest when the at least first silo device reaches a limit value of the fill level.

With The method described above ensures that there is always a sufficient level of superabsorbent Polymers of the same quality provided. In this case, in particular with regard to on the technical processing of such superabsorbent polymers an automatic, remote-controlled deployment. The silo devices, in particular as described above according to the invention so (for example, with a corresponding transport unit) one Consumer facility available posed. While the removal of superabsorbent polymers, advantageously under execution a tilting of the container, is the continuous or intermittent (at predetermined time intervals) of filling level the determined at least one silo device. You can do this Again, the above-mentioned means for use get. Now it will suggested that one filled with superabsorbent polymers, second, Silo device is requested exactly then, before the first empty is or has reached a lower limit of the level. This takes place in particular under consideration e.g. the expected consumption, the transport route, the time to fill the second silo device. The limit can be a predetermined Value, but it is also possible that this is a consumption-oriented, Variable acts. The limit value ensures that the outflow of superabsorbent polymers takes place uniformly, so that the Consumption plant with a consistent quality and quantity of superabsorbent Polymer is supplied.

According to one Development of this method is at least the determination of the filling level or requesting additional silo devices via the Internet. Most notably it is preferred that both processes, namely the determination of the degree of filling and requesting further silo devices via the Internet. This can, for example on the container installed sensors and / or other transducers for the provider of silo devices available be able to decide on the spot, when a Silo device as a replacement for the empty one is requested.

In addition, will further suggested that the date of the request further Silo devices at least depending on a parameter concerning the discharge of superabsorbent polymers, the current degree of filling and the limit value is determined. With discharge of superabsorbent In particular, polymers are parameters such as flow rate, Throughput, expected demand. meant. Thus it is clear that the Trigger point for one Requirement of further silo devices not a constant temporal Must describe, but of a variety of different Parameter dependent can be formulated. Next you can other factors are included, such as parameters, which relate to the preparation superabsorbent polymers, in particular their availability, their manufacturing process, their filling process in a silo device. Also parameters that describe the transport to the consumer facility, can at the determination of the date for the requirement of further silo devices with, for example the transport unit, the weather, the traffic situation, Pavement.

According to a development of the method, monitoring of state variables of the at least one silo device takes place via remote data transmission. Thereafter, further state variables can be monitored remotely and optionally further silo devices can be provided, even if this is not required by the Füllgad ago. Examples of such state variables are the moisture, the caking of the superabsorbent polymers, the damage to the container, overheating of the contents, the failure of sensors or measuring units, defective valves. Advantageously, a plurality of such state variables can be monitored simultaneously, whereby this need not be carried out by the consumer installation itself, but possibly by those responsible for the silo devices or the provision of superabsorbent polymers.

The The invention will be explained in more detail with reference to drawings. there It should be noted that the figures are particularly preferred embodiments of the invention and the environment of the invention show. Show it:

1 a first embodiment of a silo device with a transport unit;

2 the silo device off 1 during removal of superabsorbent polymers;

3 another embodiment of a silo device; and

4 schematically the process of monitoring or provision of superabsorbent polymers.

1 schematically shows a transport unit 11 comprising a silo device 1 , The transport unit 11 is shown as a truck, the silo device 1 to the desired location, such as a consumer facility 16 , transported. This is the silo device 1 with an adapter 10 equipped with a detachable connection with the transport unit 11 during the transport process. Is the silo device 1 at the desired location, so will be supports 23 extended, which is a self-supporting device for the container 2 the silo device 1 provide. So it's the transport unit 11 possible to move away from the silo device 1 to remove (indicated by the arrow).

2 now shows schematically the silo device 1 during the removal of superabsorbent polymers 3 , The silo device 1 includes a container 2 with a center axis 8th and two end faces 27 , being in one end face 27 an outlet 24 for the superabsorbent polymer 3 having. The outlet 24 can by a protective device 31 be protected against environmental influences. This will ensure that the superabsorbent polymer will not be contaminated. The silo device 1 also includes a holder 4 that with a pivot axis 5 , a lifting device 6 and a frame 7 is executed. The frame 7 with the supports 23 ensures a stable state of the silo device 1 ,

The frame 7 is about a pivot axis 5 with on the container 2 adjacent sub-components of the holder 4 pivotally connected. On the opposite side of the frame 7 or the front side 27 is a lifting device 6 arranged. The lifting device 6 is designed as a telescopic, hydraulically acting arm, which has a motor 22 and a controller 12 in its length is changeable. This will cause a swivel angle 9 realized between the substantially horizontally arranged frame 7 and the center axis 8th of the container 2 consists. The pivoting of the container 2 can take place during the removal of superabsorbent polymers continuously or at predetermined time intervals. In addition, it is also possible that the silo device 1 during storage and transport is positioned in a substantially horizontal position while being tilted to a fully vertical position prior to removal.

3 shows schematically and partially in perspective another embodiment of the silo device 1 , The container 2 is here in a second position 18 shown in which a removal of superabsorbent polymers 3 takes place. The container was transported or delivered 2 in the first position shown in dashed lines 17 which represents a substantially horizontal position. The change of positions was done with a lifting device 6 carried out, the container 2 around the pivot axis 5 was tilted.

The silo device 1 or the container 2 stands with a filling degree measurement 3 in contact, for example, the filling level 26 the superabsorbent polymers 3 inside the container 2 certainly. The measured values determined here are sent to an evaluation unit 19 forwarded, the information generated, which are processed processed for further processes.

The removal of the superabsorbent polymers 3 takes place via the outlet 24 , which is substantially centered to the front side shown below 27 is trained. The superabsorbent polymer 3 is from a protective layer 15 surrounded, allowing a direct contact with the wall of the container 2 is prevented. The protective layer 15 is a flexible bag made of plastic. The protective layer 15 indicates near the outlet 24 an opening through which the superabsorbent polymers 3 to the outlet 24 reach. The container is preferred 2 so tilted that the filling height of the superabsorbent polymers 3 above the outlet 24 (perpendicular to the horizontal) at most the extension 28 of the container 2 equivalent. With extension 28 is the furthest distance from walls of the container 2 in one Cross section meant. This ensures that always a relatively small filling level 26 self-compression of the superabsorbent polymers 3 conditionally, though the container 2 even a much larger container height 25 having. This is achieved by a relative movement of container 2 and bracket 4 or frame 7 is carried out.

4 schematically shows a method for providing superabsorbent polymers 3 with a silo device 1 , In this case, the degree of filling of the silo device 1 by means of a filling degree measurement 13 carried out, with the measured values determined in this way to an evaluation unit 19 to get redirected. The evaluation unit 19 takes into account the consumption of superabsorbent polymers 3 through the consumer facility 16 and transmitted by means of a transmission unit 14 optionally a signal 20 to a receiver 21 , The signal 20 includes in particular the requesting of a further silo device 1 with superabsorbent polymers 3 , in time so that these at least second silo devices 2 available at the latest when the first silo device 1 has reached a limit of the level. The delivery of a second silo device 1 can with any transport units 11 be carried out, with luggages are preferred. The consumer cheranlage 16 can also have multiple silo devices 1 include. About the outlet 24 the superabsorbent polymer enters the storage area 29 the consumer facility 16 before it is in the component contact area 30 with another in the intermediate or final product components - in the case of diaper, for example, cellulose fibers - is combined.
