DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to the technical field of machines for processing foodstuffs.
In order to produce kebabs on an industrial scale, machines that can be used for semi-automatic or fully automatic cutting up and skewering have been proposed, for instance (for information only and in no way exhaustively) the techniques disclosed in Patents FR 8316928 and 8517975.
Regardless of the solutions used, the basic principle of these various techniques is the result of using a tub in which the various layers of meat and vegetables are placed in the form of slices. The walls of the tub have vertical slits to allow the movement of cutting blades.
These various solutions have brought considerable progress in the design of kebabs compared with production by hand. However, given the operating principle of these machines, the choice of kebabs is necessarily restricted. In fact, it is only possible to use a certain type of meat and, above all, only a single type of vegetable, generally consisting of peppers, given the fact that the various ingredients have to be placed inside the tub in flat slices. The composition of the finished kebabs is therefore limited.
In addition, these kebabs always have the same appearance, i.e. they are generally of parallelepiped shape.
It therefore seems that the technique of automatic skewering cannot be used to produce kebabs of the type that can be made manually and which include, depending on the consumer's preferences, a plurality of ingredients resulting from various pieces of meat and vegetables.
U.S. Pat. No. 3,835,761 describes a machine for producing kebabs by means of recesses in which foodstuffs are placed and then subjected to a skewering action in order to produce a kebab. Nevertheless, the solution proposed in this patent is unsatisfactory. This machine uses a belt conveyor in the form of plates that are flexibly joined to each other, each plate having separate recesses which each contain an ingredient. As a result, this imposes a limit on the products to be skewered which must be cut to size to match the recess in question given the fact that each recess corresponds to one product.
In addition, the spacing between each of the recesses on a single plate to make up a kebab means that, after skewering, the ingredients on the skewer are not contiguous and are separated by a gap that essentially corresponds to the distance separating two recesses. The kebab thus obtained therefore has an unsatisfactory visual appearance.
Patent FR 2550076 also discloses an apparatus used to make up kebabs. This apparatus comprises a unit with a cover, said unit having a central opening that contains the product to be skewered. The opening communicates with two small-spit guides intended to ensure correct centering of a metal rod. It is therefore clear that this patent does not involve a machine for the automatic production of kebabs on an industrial scale and simply relates to an apparatus to make up kebabs by hand. In this patent there is no problem of continuous automatic skewering of products contained in the recess. In this patent the problem is to avoid injury when the small spit, which is made of metal, is pushed in.
SUMMARY OF THE INVENTION
The invention sets itself the objective of overcoming these drawbacks in a simple, safe, effective and rational manner.
The problem which the invention intends to solve is to automate the production of kebabs which include, in their composition, any combination of various pieces of meat and different vegetables such as tomatoes, mushrooms, peppers or onions without thereby excluding other ingredients such as prunes, pineapple and, generally speaking, any type of ingredient which is or is not cut to size.
The problem posed is therefore to industrially produce hand made-type kebabs with the objective of ensuring automatic skewering of pieces of meat and other vegetables with the possibility of using skewers or small spits made of wood in particular.
In order to solve such a problem, a machine has been devised and perfected o
