Problems solved by technology

[0005] The purpose of the present invention is to: in view of the present situation that the overall technical level and utilization rate of the by-products of shrimp processing are low, the production cost of the existing technology of producing shrimp protein peptides for feed using shrimp heads as raw materials is relatively high, and the protein content of simply fermented soybean meal cannot reach To the level of fish meal, there is a lack of growth-promoting factors in animal feed protein, and a kind of fermented protein feed additive and its processing method that can replace fish meal to a large extent can be produced by using shrimp head and other processing by-products and plant protein as raw materials

Embodiment 1

[0045] Crush fresh shrimp heads, add water to beat, sieve and separate, and separate the semi-liquid thick slurry of shrimp heads from the shrimp shells. After processing every 1,000 kilograms of shrimp heads, about 1,500 to 2,000 kilograms of semi-liquid thick slurry of shrimp heads can be obtained. Shrimp shells are directly dried as raw materials for chitin and shrimp shell powder; 1,000 kg of crushed soybean meal is mixed with 1,000-1,200 kg of thick shrimp head slurry, and an additional 200 kg of thick shrimp head slurry is added depending on the amount and thickness of the shrimp head thick slurry ~250 kg of water, make the total moisture of the raw materials in the range of 40-60%, and initially stir evenly, then add 5 kg of Bacillus subtilis, 3 kg of feed yeast, and 5 kg of Lactobacillus delbrueckii, stir and mix evenly, preferably in It can be carried out in a feed mixer, and artificial mixing can also be used when the processing volume is small; when the fermentation ...

Embodiment 2

[0047] Fresh shrimp heads are squeezed or crushed, beaten, sieved and separated to separate the semi-liquid thick pulp from the shrimp shells. After processing every 1000 kg of shrimp heads, about 1500-2000 kg of semi-liquid thick pulp can be obtained. After separation Shrimp shells are directly dried as raw materials for chitin and shrimp shell powder; 1,000-1,200 kg of shrimp head thick slurry is added to 1,000 kg of crushed soybean meal, and an additional 200-1,000 kg of shrimp head thick slurry is added depending on the amount and thickness of the shrimp head thick slurry. 250 kg of water, and initially stir evenly, then add 8 kg of Bacillus natto, 5 kg of feed yeast, and 8 kg of Streptococcus thermophilus, stir and mix evenly, and mix in a feed mixer. Use artificial mixing; start fermentation, the temperature of the fermentation environment must be above 20 degrees, if the ambient temperature is low, certain heating measures should be taken, and ventilation should be done ...

Embodiment 3

[0049] Fresh shrimp heads are squeezed or crushed, beaten, sieved and separated to separate the semi-liquid thick pulp from the shrimp shells. After processing every 1000 kg of shrimp heads, about 1500-2000 kg of semi-liquid thick pulp can be obtained. After separation Shrimp shells are directly dried as raw materials for chitin and shrimp shell powder; 1,000 kg of crushed peanut meal is mixed with 700-800 kg of shrimp head thick slurry, and an additional 200 kg of thick shrimp head slurry is added depending on the amount and thickness of the shrimp head thick slurry. ~300 kg of water, then add 10 kg of Bacillus subtilis, 5 kg of Candida tropicalis, and 8 kg of Lactobacillus delbrueckii, and initially stir evenly, mix evenly, and mix in a feed mixer, when the processing capacity is small Artificial mixing can also be used; to start fermentation, the temperature of the fermentation environment must be above 20 degrees. If the ambient temperature is low, certain heating measures ...

Abstract

The invention discloses a feed additive by mixedly fermenting shrimp heads and vegetable feed proteins and a processing method thereof. The method comprises the following steps of: performing squeezing and crushing, pulping with water, and filtration and separation on the shrimp heads to separate out shrimp shells so as to obtain a shrimp paste raw material; mixing the shrimp paste and the vegetable feed proteins according to a proportion, adding bacteria for solid fermentation, and drying and crushing to prepare fermented feed protein powder; and drying the separated shrimp shells to prepare raw materials of chitosan and shrimp shell powder. The method has the advantages of simple process, small equipment investment and low cost; and the feed additive has the advantages of full aroma of the fermented feed protein powder, good palatability, high utilization rate of proteins, rich beneficial functional nutrients such as astaxanthin, small peptide, probiotics and the like, wide application to aquatic and livestock and poultry feeds, improvement of survival rate, good animal growth effect, good feed attraction to aquatic animals, capacity of replacing fish meal in the livestock and poultry feeds, capacity of greatly replacing fish meal in high-grade aquatic feeds, remarkable reduction of feed cost, contribution to environmental protection, power saving, efficiency improvement, and remarkable social and economic benefits.

Description

technical field [0001] The invention relates to a feed additive and a processing method using mixed fermentation of shrimp heads and plant feed protein. Background technique [0002] The bulk products of prawn processing in my country are mostly frozen headless shrimp and frozen shrimp, and a large amount of offal such as shrimp heads are produced in the process of processing. Until effective value-added utilization, the shrimp breeding and processing base is located in the tropics, with high temperature and high humidity. If it is not handled in time, it will be easily spoiled and deteriorated. After being dumped, the stench is extremely bad, and mosquitoes and maggots breed in large numbers. Most of the by-products such as shrimp heads are not processed. Effective utilization not only causes waste of this bulk high-quality feed resource, but also brings prominent environmental pollution problems. Shrimp head and other processing by-products have a high comprehensive content...
