Embodiment 1

[0059] Embodiment 1, a kind of preparation method of fermented cake and fly maggot protein feed, carries out following steps successively:

[0060] 1), using cotton meal as raw material, using crushing equipment for crushing, the raw material is crushed and passed through a 40-mesh sieve, the purpose is to remove impurities such as sawdust, stone chips, and iron in the cotton meal; the raw material after crushing is obtained;

[0061] 2), adding bran accounting for 25% of the weight of the crushed raw material in the pulverized raw material obtained in step 1) and mixing to obtain a mixture; adding Bacillus subtilis accounting for 5% of the total weight of the mixture in the mixture and mixing evenly; The Bacillus subtilis is a powder, and the number of effective viable bacteria is 10 billion / g;

[0062] 3), add pure water modulation in the product of step 2) gained, obtain the fermentation medium that moisture content is 45% (weight content); , first measure the moisture con...

Embodiment 2

[0072] Embodiment 2, a kind of preparation method of fermented cake and fly maggot protein feed, carries out following steps successively:

[0073] 1), use rapeseed meal as raw material, utilize crushing equipment to carry out pulverization, after the raw material is pulverized, pass through 50 mesh sieves, the purpose is to remove impurities such as sawdust, stone chips, iron in the rapeseed meal; Obtain the raw material after pulverization;

[0074] 2), adding bran accounting for 50% of the weight of the crushed raw material to the pulverized raw material obtained in step 1) for mixing, adding Bacillus subtilis accounting for 2.5% of the total weight of the mixture in the mixture and mixing evenly; the Bacillus subtilis It is a powder, and the number of effective viable bacteria is 30 billion / g;

[0075] 3), adding pure water to the product obtained in step 2) for modulation, to obtain a fermentation medium with a water content of 60% (weight content);

[0076] 4), the prep...

Embodiment 3

[0082] [0082] Embodiment 3, a kind of preparation method of fermented cake and fly maggot protein feed, carries out following steps successively:

[0083] 1) Using soybean meal as raw material, crushing equipment is used to crush the raw material. After the raw material is crushed, it is passed through a 50-mesh sieve to remove impurities such as sawdust, stone chips, and iron in the soybean meal; the crushed raw material is obtained;

[0084] 2), adding bran accounting for 75% of the weight of the crushed raw material to the pulverized raw material obtained in step 1) for mixing, adding Bacillus subtilis accounting for 1‰ of the total weight of the mixture in the mixture and mixing evenly; the Bacillus subtilis As a powder, the number of effective viable bacteria is 50 billion / g;

[0085] 3), adding pure water to the product obtained in step 2) for modulation, to obtain a fermentation medium with a water content of 75% (weight content);

[0086] 4), the preparation method ...

Abstract

The invention discloses a preparation method of a fermentation cake and maggot protein feed, and the method comprises the following steps: 1) smashing subsidiary agricultural product cakes serving as raw materials; 2) adding bran and bacillus subtilis into the smashed raw materials and uniformly mixing; 3) adding water in the product obtained in the step 2) and concocting to obtain a fermentationmedium; 4) fermenting the fermentation medium and engineering fly eggs in a fermentation reactor; and 5) separating the product through fermentation in the step 4) and extracting the maggot larvae toobtain a ferment; and sequentially and respectively drying and smashing the maggot larvae and the ferment to obtain maggot protein and fermentation protein feed respectively. The maggot protein and fermentation protein feed prepared by the method have the characteristics of high protein content, nutritive equilibrium and the like.

Description

technical field [0001] The invention relates to a method for producing high-quality feed protein by using microbial solid-state fermentation and fly maggots to biotransform low-quality agricultural by-products. Background technique [0002] With the development of my country's feed industry, the shortage of protein feed raw materials has become the first limiting factor for the development of feed industry. [0003] my country is a big oil crop planting country in the world. The output of rapeseed, peanut, cottonseed and sesame ranks first in the world. A large amount of cake will be produced in the process of producing edible oil every year. However, due to the low level of processing technology, production The quality of the cake is not high and most of the cake contains a lot of anti-nutritional factors, so that the utilization rate of the cake is not high. [0004] The crude protein content of soybean meal is very high, which is the basic raw material for the preparation...
