Embodiment 1

[0045] Step 1 Garbage Disinfection and Sterilization

[0046] Under the condition of 108-120 ℃, the garbage of the meat joint factory is sterilized at high temperature for 24-36 hours.

[0047] Step 2 Garbage sorting

[0048] Dry and pulverize with a rake dryer, pass through a 60-80 mesh sieve to obtain meat powder;

[0049] The bones are dried and pulverized by a rake dryer, passed through a 60-80 mesh sieve, and filtered to obtain bone meal;

[0050] Then add 0.2% Aspergillus oryzae powder and mix well, ferment in a ventilated fermentation room for 36-48 hours, dry and pulverize into fermented blood meal;

[0051] The hair is soaked in an aqueous solution of keratinase, and enzymatically hydrolyzed at 45-60° C. for 2-3 hours to obtain an enzymatic hydrolyzate.

[0052] Step 3 Prepare protein feed

[0053] The weight ratio of the mixture 1 to the preservative is 1000:2-4; the mixture is placed in a rake dryer, mixed and dried at 110-130°C to obtain protein feed.

Abstract

The invention is applicable to the technical field of livestock waste utilization, and provides a method for producing protein feed by using the garbage from a meat processing factory, which comprisesthe following steps of: sterilizing the garbage from the meat processing factory at high temperature; dehydrating and degreasing the meat after classification; drying and pulverizing, sieving with a60-80 mesh sieve to obtain meat powder; drying and pulverizing the bones, sieving with a 60-80 mesh sieve, and filtering to obtain bone powder; spray-drying the blood to obtain blood powder; adding aspergillus oryzae powder for fermenting, oven-drying and pulverizing to obtain fermented blood powder; spray-drying the hair after enzymolysis with keratinase to obtain hair powder; mixing the meat powder, the bone meal, the fermented blood powder, the hair powder and preservative, and drying and pulverizing to obtain protein feed. Therefore, the waste of the meat processing factory is changed intowealth by using the method, and the nutrient content of the produced protein feed is high.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry waste utilization, in particular to a method for producing protein feed by using waste from a meat processing factory. Background technique [0002] With the rapid development of aquaculture and feed industry, protein feed is seriously insufficient, which is a common problem in the current production of compound feed. Therefore, all kinds of protein feed resources are being developed at home and abroad, especially the development of animal protein resources. [0003] In the current livestock breeding industry chain, the meat factory is an important part. The meat factory produces a lot of garbage during the processing process, mainly the leftovers of livestock and poultry meat, bones, hair, etc. These garbage accumulate in large quantities and breed Bacteria cause serious pollution to the air, soil and water environment, and often cause great distress to residents living nearby. ...
