DESCRIPTION:
BRIEF SUMMARY
This invention relates to a method of and a machine for disintegrating materials, more particularly food products. The machine according to the invention is primarily intended for the disintegration of food products in the form of fairly large pieces or blocks, such as sausages and compressed meats, but above all cheese.
There are various known machines for disintegrating food products, such as for example graters, slicing machines, mills, etc. These known machines have satisfied the requirements made of them fairly well where it has been a question of producing relatively large pieces, such as slices, or where the products to be disintegrated have been relatively dry and firm, such as raw vegetables, hard and dry cheeses, etc. It has also been possible not only to disintegrate but also to portion the material.
However, disintegration and portioning have involved problems where the products in question have been fairly soft and sticky, such as various delicatessen and cheeses having a high or moderately high fat content. It has been particularly difficult to disintegrate cheese because, due to the fatty and sticky consistency of cheese, the particles obtained have tended to adhere to the cutting implement or even to one another to form fairly large lumps. Hitherto, there has been no machine capable of simultaneously disintegrating and, if necessary, portioning materials as difficult as these in a variable manner. This has given rise to considerable difficulties in the automatic machinery used for the production of prepared dishes, for example when grated cheese has to be sprinkled over a pizza or when a gratin has to be subsequently frozen and delivered in this state to the consumer for final preparation. If, in this case, the cheese is not uniformly distributed over the dish, it will melt unevenly during the final heating so that the finished dish will have a less appetizing appearance.
The present invention enables the disadvantages referred to above to be obviated and provides for the uniform disintegration of food products which, previously, were difficult to use from this point of view. The method and the machine according to the invention are particularly intended for the disintegration of cheese, although other food products in piece form, such as minced meat and pressed ham, may advantageously be disintegrated in accordance with the invention.
In general, conventional machines for disintegrating various food products in piece form have been completely different models according to the type of food product to be treated. It would be extremely desirable both from the practical and from the economic point of view for different types of food products to be able to be treated essentially in the same apparatus in which only a few elements would need to be replaced for adaptation to the different mechanical and rheological properties of different food products. The present invention enables this object to be achieved and the same apparatus may be used for different food products, such as cheese, meat and delicatessen, for example pressed ham and minced meat, sausage either in the form of fairly large individual sausages or in the form of several small sausages together, and other materials, only the elements used for the actual disintegration process having to be specially adapted to the type of food product to be treated.
The method according to the invention is characterised in that the material to be disintegrated is fed to a driven disintegrating element which makes a reciprocating movement substantially parallel to one surface of the material and, in doing so, comminutes the material on that surface. The material is preferably fed intermittently to the disintegrating element which is preferably in the form of a rotary disintegrating element of which the axis of rotation is parallel to the treated surface.
The invention also relates to a machine for disintegrating materials which comprises a driven disintegrating element designed to receive a reciprocating movement substantially parallel to one surfac
