Abstract

A pet chew includes an outer layer and an inner layer, the outer and inner layers being laminated and rolled into a cylindrical shape having knots at both ends, the outer layer including, in weight percent, 28 to 49 percent plant-based material, at least 30 percent meat-based material and at least 20 percent animal hide-based material. Preparation methods are also disclosed.

Claims

1. A pet chew comprising:

an outer layer and an inner layer, the outer and inner layers being laminated and rolled into a cylindrical shape having knots at both ends, the outer layer including, in weight percent, 28 to 49 percent plant-based material, at least 30 percent meat-based material and at least 20 percent animal hide-based material.

2. The pet chew as recited in claim 1 wherein the plant-based material includes corn starch and wheat flour, the meat-based material beef and chicken and the animal-hide based material ox or cow split leather leftovers.

3. The pet chew as recited in claim 2 wherein the plant-based material includes, in weight percent, 28-33 corn starch and 14-16 wheat flour, the meat-based material 10-12 beef and 20-23 chicken breast and the animal-hide based material 20-23 ox or cow split leather leftovers.

4. The pet chew as recited in claim 1 further comprising auxiliary material including, in weight percent, 4-4.5 glycerin, 1.5-2 fish oil, 1-1.5 branching oligosaccharide, 0.9-1 salt, 0.01-0.015 multiple vitamin, 0.01-0.015 mineral, 0.01 potassium sorbate, 0.2 natural essence and 0.2 edible pigment.

5. The pet chew as recited in claim 1 wherein the inner layer includes, in weight percent, 90 chicken breast, 8 corn starch, 2 glycerin, 0.02 potassium sorbate and 0.1 edible pigment.

6. The pet chew as recited in claim 1 wherein the inner layer is jerky.

7. A preparation method for the pet chew as recited in claim 1 comprising:

processing the animal-hide based material in a rotary drum, agitating the plant-based material, meat-based material, and animal-hide based material, extruding the agitated material, and slicing the agitated material into sheets.

8. A preparation method for pet chews comprising:

an outer layer processing, an inner layer processing and a forming procedure;

the outer layer processing including;

treating ox or cow split leather leftovers in a rotary drum, then dried, pulverized and baked to crisp, and finally ground into fine powder;

processing beef and chicken breast in a meat grinder into paste□

agitating and mixing corn starch, wheat powder, the treated ox or cow split leather leftovers, and branching oligosaccharide and mineral in an agitator;

putting the processed beef and chicken breast into the agitator and agitating the materials in the agitator once more; and

dyeing, flavoring and beating the leather leftover and chicken and beef mixture in a stainless steel dough maker by beating and rotating the leather leftover and chicken and beef mixture while adding a mixed liquid composed of glycerin, fish oil, multiple vitamin, hydrous edible salt, hydrous potassium sorbate, natural essence and food pigment; and

aging and slice-making the dyes, flavored and beat material into an extruder, and the material, after being aged, being cut into slices through dies.

9. The method as recited in claim 8 wherein the inner layer processing includes the following steps:

mixing chicken breast, corn starch, glycerin, potassium sorbate and food pigment into a stainless steel dough maker and beat;

extruding the mixed material and and then slicing the extruded mixed material into slices.

10. The method as recited in claim 9 wherein the forming procedure includes the following steps:

laminating the slices from the outer layer processing and the inner layer processing, rolling the laminated slices into a cylindrical shape and knotting both ends.

11. The method as recited in claim 8 wherein the processing of the ox or cow split leather leftovers in the rotating drum includes the following procedures:

cleaning the ox or cow split leather, then subjecting it to deliming treatmenty, said split leather is mixed with water in a ratio of 1;

3 and then add ammonium chloride in 2.5-3.5 percent of the above mixture weight;

agitating the mixture until the pH value at the section of said split leather is up to 13-15 and then removing said split leather for its cleaning;

depending on the weight of said split leather processed in Step 1, putting said split leather into 0.5-1% sulfur and agitating until said split leather expands and the pH value of said split leather is up to 3-5; and

bleaching and disinfecting said split leather by putting into 0.5-1% hydrogen peroxide and agitating until the pH value at the section of said split leather is up to 6-8; and

flushing said leather.
