BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a process for producing shaped bodies from pasty foodstuffs by plastic deformation, wherein a quantity of the foodstuff is placed between dies which are arranged at a distance from each other and the two dies are then moved toward each other, so that the foodstuff is plastically deformed and any excess quantity of foodstuff is squeezed out of the gap between the two dies.
A process of this type has the disadvantage, that after the plastic deformation, the foodstuff must be grasped for removing it from the dies, which means that there is the danger of an unintentional deformation of the soft mass. In addition, there is the danger of contamination of the foodstuff if the operator does not wear protective gloves. This also applies to the removal of the excess quantity of foodstuff squeezed out of the gap between the dies.
SUMMARY OF THE INVENTION
Therefore, it is the object of the invention to improve the process of the type described above in such a way that an unintentional deformation as well as a contamination of the shaped pasty foodstuff is excluded when the foodstuff is removed from the dies.
In accordance with the invention, this object is met by placing the pasty foodstuff between two foil layers which laterally project beyond the dies, by removing the foodstuff after the opening of the dies by means of the projecting portions of the foil layers and subsequently cooling the foodstuff to solidification temperature and by then breaking off from the shaped body the excess quantity of foodstuff located outside of the contour of the shaped body formed by the foodstuff.
After opening of the mold, the shaped body formed by the pasty foodstuff can be removed in a simple manner from the dies by grasping a protruding portion of the two foil layers. Since the operator does not contact the shaped body during this procedure, any unintentional deformation or contamination is practically excluded. After cooling, the two foil layers can be easily pulled off from the shaped body, wherein there is also no danger of an unintentional deformation because the shaped body is no longer plastic, but has solidified.
The foil layers can be pulled off in such a way that the shaped body as well as the excess quantity of foodstuff located outside of the contour thereof is protected against direct contact.
Accordingly, the arrangement of the pasty foodstuff between two foil layers, on the one hand, and cooling of the plastically deformed foodstuff to solidification temperature, on the other hand, assist each other because only the combination of these two steps makes it possible to produce any selected shape of a pasty foodstuff in a simple manner.
The process according to the invention can be used with a variety of foodstuffs which are deformable at room temperature, wherein butter, margarine, soft cheese, cooked rice, flour dough, potato dough, ice cream, chopped meat and fish mass are mentioned as examples.
BRIEF DESCRIPTION OF THE DRAWING
The invention shall be explained in more detail below with the aid of an embodiment illustrated in the drawing. In the drawing:
FIG. 1 is a schematic cross-sectional view of a mold with a pasty foodstuff arranged in the mold,
FIG. 2 is an illustration similar to FIG. 1 after the closing of the mold, and
FIG. 3 is a cross-section of the foodstuff removed from the mold after cooling.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 of the drawing shows a mold composed of two dies 10, 12, wherein at least one of the dies is movable. A quantity 14 of a pasty foodstuff, in the following called "butter" for simplicity's sake, is placed on an expandable foil 16 of polyethylene which is then folded onto itself. The foil is dimensioned in such a way that, after folding, the foil has a greater cross-sectional size than the dies 10, 12. Accordingly, the foil 16 can be grasped at the protruding portions 18 for placing the butter quantity 14 on the lower die 10.
When the two dies 10, 12 are subsequently moved toward each other, the condition sh
