Description

A method for making dog chews from shredded cowhide

technical field

The invention belongs to the field of making pet products, in particular to a method for making pet dog chews from shredded cowhide.

Background technique

Pet dog chews are a traditional product generally accepted by consumers and are used for pet teething and toys. Dog chews are a kind of pet toy or pet feed, which can be made into various shapes of pet products according to the pet's preferences. The main ingredients are made of beef cowhide, pork skin, sawdust and other dog food through special processing. It is a high-protein product for pet dogs. 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. of waste.

Contents of the invention

In view of the above defects, the present invention provides a method for making dog chews from scraps of scraped skins, which are recyclable, natural, greatly reduced in cost, simple in process, and easy to produce, so that scraps of animal skins can be made into various kinds of dog chews through a series of processes. shaped dog chews.

The present invention adopts following technical scheme:
