Embodiment 1

[0016] Take 100 kg of collected crayfish shells, wash them, put them in a high-temperature disinfection cabinet for disinfection and sterilization, adjust the temperature to 121° C., and sterilize for 60 minutes. The sterilized crayfish shells are dried in a steam drying oven, dried at 60° C. for 60 minutes, cooled naturally, crushed and passed through a 150-mesh analytical sieve to obtain finished shrimp shell powder.

[0017] The finished product is sampled and tested, and its crude protein content is 42.1%, and its crude ash content is 17.4%.

Embodiment 2

[0019] Take 100 kg of collected crayfish shells, wash them, put them in a high-temperature disinfection cabinet for disinfection and sterilization, adjust the temperature to 134° C., and sterilize for 30 minutes. The sterilized crayfish shells are dried in a steam drying oven, dried at 60°C for 100 minutes, cooled naturally, crushed and passed through a 150-mesh analytical sieve to obtain finished shrimp shell powder.

[0020] The finished product is sampled and tested, and its crude protein content is 41.5%, and its crude ash content is 18.6%.

Abstract

The invention discloses a method for producing feed shrimp shell powder by utilizing abandoned crawfish, and the method comprises the following steps: the shells of the abandoned crawfish are firstly collected and washed to be clean; then the clean shells of the crawfish are carried out the high-temperature disinfection and sterilization; the shells of the crawfish after the disinfection and the sterilization are finally carried out drying, smashing and screening treatment, thereby obtaining the finished product. The method recycles the shells of the abandoned crawfish and carried out the appropriate treatment for comprehensive utilization and production of the shrimp shell powder, the method can not only avoid the waste of resources and reduce the production cost, but can also have short production cycle, high product yield and stable product quality and avoid the environmental pollution.

Description

technical field [0001] The invention relates to a method for preparing feed, in particular to a method for preparing feed additives from kitchen waste. Background technique [0002] As a feed additive, general shrimp shell powder has a crude protein content of about 40%, a crude ash content of about 30%, and contains a large amount of unsaturated fatty acids, choline, phospholipids, sterols and astaxanthin with coloring effects. There are a large number of experimental reports that shrimp shell powder can not only provide protein for livestock and poultry, but also has some special effects. For example, adding 3% shrimp shell powder to chicken feed can help broiler toes and egg yolk color; adding 3% to 5% shrimp shell powder to pig feed can improve the disease resistance of piglets and improve the color of pork; in shrimp feed Adding 10% to 15% shrimp shell powder can also achieve a good growth-promoting effect. [0003] Crayfish belong to the large family of arthropods, a...
