Problems solved by technology

However, in the production of dog chews, there are a lot of leftover scraps and skins. That is to say, the bone-bonding or bone-pressing series of dog chews on the market all use pig and cowhide, which are layered, neutralized, rinsed, dried and cut into appropriate Dog chew products with different lengths and widths can be made into different sizes, and the trimmed leftovers can only be used to make the core and granular products of the product, and their usage is very limited, which leads to most of the leftovers being wasted. waste of

Embodiment 1

[0022] 1) Use 1mol / L urea for fresh cowhide scraps at 40 o C soaked for 3 hours, the amount of fresh cowhide leftovers is 10g / l;

[0023] 2) Mix the processed cowhide scraps with tap water at a mass ratio of 1:3 and mix at 20 o Soak in C water bath for 3 hours;

[0024] 3) Grind the soaked cowhide in a meat grinder to make it into minced meat, wherein the speed of the meat grinder is 700r / min, and the diameter of the mesh hole is 8mm;

[0025] 4) Mix the minced meat and tap water at a mass ratio of 1:1 to prepare a slurry. The slurry is stirred by an electric stirrer at a vacuum of 0.01 MPa at 40°C to evaporate under reduced pressure, and the rotation speed of the electric stirrer is 100 r / min;

[0026] 5) When the water content in the slurry is reduced to 50%, add 2% cassava flour, 1% bone meal, 3% skimmed milk powder, 2% seaweed fiber, 2% grape skin and seeds, and 5% pig skin pulp. The above ingredient ratios are the percentages of the ingredients in the dry cowhide mass,...

Abstract

The invention relates to a method for preparing pet dog chew from cattle hide leather fragments. The method comprises the following steps: soaking cattle hide leather leftovers into 30DEG C water bath; then mincing through a meat mincer; pulping through a food processor; drying the pulp; injecting into a mold; drying and sizing; and sterilizing. For recycling, the cattle hide leather fragments are subjected to a series of processing into various shapes of dog chew products pets like very much, the pet dog chew is natural, rich in nutrition and capable of cleaning teeth and protecting health. The pet dog chew can meet demand of pet dogs of different types and ages, the processing is simple, and the effect is desirable.
