DESCRIPTION:

BRIEF SUMMARY
The invention relates to an apparatus for dividing deep-frozen foodstuffs, more particularly fish, in the form of parallelipipedic bodies, such as slabs, into a plurality of smaller parallelipipedic units, such as fingers, comprising: a table which forms on its top side a conveying distance for the parallelipipedic bodies, over which the parallelipipedic bodies can be slid by conveying means; a plurality of spaced-out saw elements disposed one beside the other; hold-down elements engaging with the top side of the parallelipipedic bodies and/or smaller units; and an applicator unit, equipped with blowing nozzles for detached foodstuffs.
Deep-frozen foodstuffs can be divided into smaller units only by sawing. Inevitably there is a considerable accumulation of detached material, depending on the thickness of the sawing elements. Although the cutting loss due to the detached material cannot be avoided, to keep such losses low as possible in a prior art apparatus of the kind specified (DE 3512488 C2) the saw elements, taking the form of circular saw blades, are disposed above the table top and enclosed by a suspended hood equipped with blowing nozzles to apply intercepted detached material on to the smaller parallelipipedic units. Interception and application are boosted by a contact pressure roller bearing against the smaller units. One disadvantage of that manner of recovering a proportion of the detached foodstuff is that due to the reapplied detached material the small parallelipipedic units again become caked together at their parting lines and the appearance of the surface of the units is not optimum.
It is an object of the invention to provide an apparatus of the kind specified which ensures that after the separation of the parallelipipedic bodies into smaller units they do not again become caked together at the separating lines and also that the appearance of the surface of the smaller parallelipipedic units remains practically unspoilt by applying detached foodstuffs.
This problem is solved according to the invention by the feature that the saw elements are constructed in the form of saw belts which run upwards from the table and are disposed in the blowing air flow of the blowing nozzles, which is directed upstream of the saw belts in the conveying direction on to the conveying distance of the table situated thereabove.
The use of saw belts in conjunction with the blowing air stream and the place of application upstream of the cut ensures minimum cutting loss and at the same time an optimum appearance of the other parallelipipedic units. The smaller units cannot cake together again, since after cutting no detached foodstuff is applied which may get into the zone of the parting lines. The cuts therefore remain clean even at the parting lines.
The fact that the detached material is applied to the parallelipipedic deep-frozen bodies at a place where it has not yet been locally heated by the cutting ensures that said material is caked back uniformly over the whole surface by the cold content of the bodies.
According to one feature of the invention upstream of the saw belts in the conveying direction a contact pressure roller is provided which bears against the top side of the parallelipipedic bodies. The contact pressure roller can be so positioned that in known manner it presses and smooths the detached foodstuffs on to the surface of the as yet undivided bodies. The contact pressure roller operates particularly effectively if it is heated. Its effect can be further enhanced if the blowing air stream is directed at the contact pressure roller, so that the detached material does not pass directly on to the parallelipipedic bodies, but only via the contact pressure roller. If the roller is heated, the detached material is further softened up and can then be even more satisfactorily applied. This effect can also be achieved or boosted by the blown air itself being heated.
According to another feature of the invention, in the conveying direction of the parallelipipedic bodies spacer discs which enter the sep
