Description

Die Erfindung betrifft eine Einrichtung zum Schneiden von Lebensmitteln mit Ultraschall und ultraschallerregte Schneidwerkzeuge, insbesondere zum Schneiden von Teig-und Backwaren, auch geeignet zum Schneiden von beispielsweise Käse, Fisch, Fruchtschnitten und ähnlichen Produkten.The invention relates to a device for cutting food with ultrasound and ultrasonically excited cutting tools, in particular for cutting dough and bakery products, also suitable for cutting, for example, cheese, fish, fruit slices and similar products.

Das Schneiden von Lebensmittelprodukten mittels ultraschallerregter Messer ist bekannt und findet überwiegend im industriellen Bereich Anwendung.
Derartige Schneidvorrichtungen und Messer sind in der WO 94/22645 und der EP 084 2018 B1 beschrieben.
Auf eine Schneidvorrichtung für ein elektrisches Haushaltsgerät bezieht sich die WO 94/22645 , welche mit einem Messer ausgebildet ist, welches durch einen Piezoschwinger angeregt wird und ein Messer zum Einsatz kommt, welches als eine längliche Klinge ausgebildet ist, die an einem Ende nahezu rechtwinklig abgewinkelt ist und der Biegeradius dieser Abwinklung und der Messerwerkstoff an die Frequenz des Piezoschwingers angepasst ist.
Ein Messer in Form einer rotierenden Scheibe, welche ultraschallerregt wird, beschreibt die EP 084 2018 B1 . Dieses Schneidwerkzeug wird durch einen Ultraschallgenerator erregt und zusätzlich in eine Rotation versetzt, so dass hier ein kombiniertes Schneidwerkzeug vorgestellt wird, welches, um erforderliche Schnittqualitäten zu erreichen, zum einen ultraschallerregt wird, aber zusätzlich eine rotative Bewegung benötigt, um den geforderten qualitativen Anforderungen zu entsprechen.The cutting of food products by means of ultrasonically excited knives is known and predominantly used in the industrial sector.
Such cutting devices and knives are in the WO 94/22645 and the EP 084 2018 B1 described.

A knife in the form of a rotating disk, which is excited by ultrasound, describes the EP 084 2018 B1 , This cutting tool is excited by an ultrasonic generator and additionally set in rotation, so that here a combined cutting tool is presented, which, in order to achieve required cutting qualities, on the one hand ultrasound excited, but in addition requires a rotary motion to meet the required qualitative requirements ,

Nachteilig bei diesen Lösungen ist, dass deren Einsatzgebiete sehr eng begrenzt sind und deren Anwendungen mit hohen technischen Aufwendungen und finanziellen Kosten verbunden sind.A disadvantage of these solutions is that their applications are very limited and their applications are associated with high technical costs and financial costs.

So ist es Aufgabe der vorliegenden Erfindung, eine Einrichtung zum Schneiden von Lebensmitteln mittels Ultraschall zu schaffen, welche im industriellen Bereich anwendbar ist und diese Einrichtung mit ultraschallerregten Schneidwerkzeugen ausgebildet ist, mit denen insbesondere Teig- und Backwaren, aber auch andere Lebensmittel, wie Käse, Fisch, Fruchtschnitten und ähnliche Produkte, geschnitten werden können, dies unter Vermeidung der Nachteile der bekannten Lösungen.Thus, it is an object of the present invention to provide a device for cutting food by means of ultrasound, which is applicable in the industrial sector and this device is formed with ultrasound-excited cutting tools, with which in particular dough and bakery products, but also other foods, such as cheese, Fish, fruit slices and similar products can be cut, while avoiding the disadvantages of the known solutions.

Die vorteilhaften Schneideffekte dieser vorgestellten Lösung ergeben sich aus der Zuführung des Schneidgutes zu dem in der Einrichtung starr angeordneten Schneidwerkzeug, welches mit einer auf das Produkt abgestimmten Geometrie ausgebildet ist und in bekannter Art und Weise mit Ultraschall angeregt und so in Schwingungen zwischen 18 bis 30 kHz versetzt wird.Thus, according to the invention food cutting machines of the type mentioned are formed with means which, taking into account the respective cutting processes to be realized, are arranged in the corresponding cutting machine in such a way that they are carriers of the respective cutting tools and ensure the positioning of the cutting tools for the food product to be cut , regardless of whether cutting operations in the longitudinal or transverse direction to be cut product to be performed.
The invention also includes that the geometric shapes of the ultrasonically excited cutting tools are adapted to the material to be cut and, analogously, the assignment of the ultrasonic transducer to the sonotrode, which is connected to the cutting tool. The cutting tools are adapted in shape to the respective cutting task and arranged on the device in the technological process of the cutting machine, this taking into account the supply of the material to be cut, the cutting modules, securing the position of the required sound and safety elements and the removal of the material to be cut from the machine including the parameter control.

The operation and operation of the cutting devices corresponds to the cutting device 2 according to FIG. 8 b.

Eine Doppelanordnung von Schneideinrichtungen 2 zu einem Schneidgut 8, welches sich beispielsweise auf einem Transportband 7 befindet, zeigt die Figur 10. Bei dieser Variante sind die als Klingen ausgebildeten Schneidwerkzeuge 1 bis zu einer Länge von 300 mm ausgebildet, einseitig in der zugehörigen Schneideinrichtung 2 eingespannt und werden in ihrer Längsrichtung durch den jeweils zugeordneten US-Wandler 6 angeregt.A double arrangement of cutting devices 2 to a cutting material 8, which is located for example on a conveyor belt 7, shows the FIG. 10 , In this variant, the cutting tools 1 designed as blades are designed to a length of 300 mm, are clamped on one side in the associated cutting device 2 and are excited in their longitudinal direction by the respectively associated US converter 6.

Die Darstellung nach Figur 11 zeigt den Einsatz eines Schneidwerkzeuges 1 in Ausbildung einer Spatenklinge, welche beispielsweise aus einem sehr dünnen Blech, ca. 1 mm, hergestellt ist und in bereits beschriebener Art und Weise in der Schneideinrichtung 2 befestigt ist und über den vorgesehenen US-Wandler 6 erregt wird. Vorteilhaft bei dieser Ausführung ist, dass die Spatenklinge eine zusätzliche Bewegung ausführt, indem die Spatenklinge auf und ab bewegt wird, wie mit den Pfeilrichtungen dokumentiert. Die Spatenklinge selbst ist fest in der Schneideinrichtung 2 eingespannt.The representation after FIG. 11 shows the use of a cutting tool 1 in the form of a spade blade, which is for example made of a very thin sheet, about 1 mm, and is fixed in the manner already described in the cutting device 2 and is excited via the provided US converter 6. An advantage of this design is that the spade blade performs an additional movement by moving the spade blade up and down as documented with the directions of the arrows. The spade blade itself is firmly clamped in the cutter 2.

Derart ausgebildete Schneidwerkzeuge 1 sind kostengünstig herstellbar, ihre dickenmäßige Ausgestaltung wirkt sich positiv auf das Schneidgut 8 aus, insbesondere durch eine sehr geringe Verdrängung des Materials im unmittelbaren Schneidprozess. Ferner ist vorteilhaft, dass die vorgestellten Schneidwerkzeuge 1 auswechselbar sind, somit die Effektivität beim Schneiden selbst und die Effektivität von Schneidmaschinen erhöht werden.Such formed cutting tools 1 are inexpensive to produce, their thickness-wise configuration has a positive effect on the cutting material 8, in particular by a very low displacement of the material in the immediate cutting process. Furthermore, it is advantageous that the presented cutting tools 1 are interchangeable, thus the effectiveness of cutting itself and the effectiveness of cutting machines are increased.
