Abstract

A process for the production of dehydrated foodstuffs, feedstuffs or plant fertilizers includes the following steps: (a) preparing protein-containing animal matter to a particulate size acceptable to homogenizing equipment; (b) subjecting the comminuted matter to ultra homogenization; (c) heating the resultant homogenate to a temperature of between about 50° C. and 85° C. to agglomerate the protein; (d) granulating the agglomerate; (e) drying the granules at a temperature not greater than 95° C. until their moisture content is within the range of about 20% to about 50% by weight; (f) passing the partially dried granules through a mincer to form kibbles; (g) drying the kibbled material to achieve a moisture content not more than 8% by weight.

Claims

1. A process for the manufacture of dehydrated foodstuffs, feedstuffs, or plant fertilizers comprising the steps of:

(a) subjecting raw or uncooked, or substantially raw or uncooked, protein-containing animal matter to ultra homogenization, prior to the application of heat, to yield an average particulate size of less than about three microns and to reduce any tendons, skin or connective tissues to blend with muscle tissues and to break down fibrous tissue and emulsify associated fats resulting in a smooth, creamy, liquid to semi-solid homogenate;

(b) heating the resulting homogenate to form a protein agglomerate to effect gelation of said protein;

(c) granulating the resulting agglomerate;

(d) partially drying the granulated agglomerate;

(e) kibbling the resultant partially dried and granulated agglomerate to break open case hardened protein film formed in step (d); and

(f) drying the resultant Kibbles.

2. The process of claim 1 wherein the heat agglomeration of the protein achieved in step (b) is within a temperature ranging from about 50°

to about 85°

C.

3. The process of claim 1 wherein the granules are partially dried at a temperature not greater than 95°

C.

4. The process of claim 1 wherein the granules are partially dried to a moisture content within the range of about 20% to about 50% by weight.

5. The process of claim 1 wherein the kibbles are dried to a moisture content of not more than 8%.

6. The process in accordance with claim 1, including the additional step of grinding the dried kibbles.

7. A process for the manufacture of a dehydrated protein-containing product comprising the following steps in order:

(a) subjecting proteinaceous animal matter to ultra homogenization prior to the application of heat, to yield an average particulate size of less than about 3 microns and to reduce any tendons, skin or connective tissues to blend with muscle tissues and to break down fibrous tissue and emulsify associated fats resulting in a smooth, creamy, liquid to semi-solid homogenate;

(b) heating the resultant homogenate to a temperature of between about 50°

C. and 85°

C. to agglomerate the protein in the homogenate to effect gelation of said protein;

(c) granulating the resultant agglomerate;

(d) partially drying the resultant granules at a temperature not greater than about 95°

C. until their moisture content is within the range of about 20% to about 50% by weight;

(e) kibbling the resultant partially dried granules to break open case hardened protein film formed in step (d); and

(f) drying the resultant kibbles to achieve a moisture content not more than about 8% by weight.

8. The process as recited in claim 7, further comprising the additional step of grinding the dried kibbles.
