Abstract
Abstract A munchy, especially for dogs and cats, is manufactured from rawhide or spetches and/or split thereof by dehydration, pressing and chopping of the resulting product, and extrusion of same together with a starch material through several heating zones and a die plate, whereupon the extruded product may be cut. By this method it becomes possible to use the hide wastes, available in large quantities from the production of leather, for the manufacturing of munchies and snacks for dogs and cats, thus sparing proper hide material that can now be used for finer applications.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
116 words
A method of manufacturing snacks for pets, said method consisting essentially of the steps of: (a) providing tannery wastes produced from liming and including sulfur and lime therein; (b) dehydrating the tannery wastes to form a dehydrated product; (c) chopping the dehydrated product; (d) mixing the chopped dehydrated material with a starch material to form a starch-containing mixture; (e) extruding the starch-containing mixture at an elevated temperature using an extruder with a worm mounted on a die plate with holes about 61/4 millimeters in diameter and with five heating zones, and wherein the material is heated intensely in the second and fourth zones and is cooled in the fifth zone; and (f) cooling the extruded mixture.
