Problems solved by technology

These cultivation wastes called fungus chaff are discarded randomly in the cultivation area because they are not reused and disposed of, which not only encroach on the land, but also cause serious pollution to the rural environment, endangering the healthy development of the edible fungus industry and the construction of a new countryside.
[0003] However, there are some problems in the breeding of livestock, poultry and fish: due to reasons such as mad cow disease, the state has suspended the use of some animal-sourced proteins, resulting in a serious shortage of raw protein sources for farming. In addition, the deep processing of grains and the gradual promotion and application of clean fuel alcohol are in conflict with the people. Competing for grain, and competition for grain with breeding is becoming more and more prominent, which makes the price of conventional feed materials such as corn and soybeans high, resulting in high cost of breeding, poor efficiency, and a large gap in concentrated feed
Although this solution can solve the problems in the production of bacterial protein with penicillin residue as raw material, it has narrow application range, complicated treatment process, high temperature, difficult control of process conditions, high equipment requirements, and is not suitable for relatively extensive feed. processing

Embodiment 1

[0022] First remove the plastic bag film outside the discarded bacteria bag, and crush the bacteria group into pieces, then put it into the steam flash tank, and feed steam to make the steam pressure rise to 0.3Mpa. After maintaining for 30 minutes, Then raise the pressure to 0.4Mpa, and immediately exhaust and depressurize to normal pressure; by weight, add 10 parts of wheat bran, 8 parts of bacteria foot, 1.0 part of urea, and 0.5 parts of ammonium sulfate 10 parts of rapeseed rice, 0.05 parts of potassium dihydrogen phosphate, 0.03 parts of magnesium sulfate, 5 parts of self-made yeast culture solution, 5 parts of Trichoderma culture solution and 30 parts of water, mix well, and culture at 28°C for 2 days; The protein feed additive obtained after mixed fermentation is dried until the water content is less than 12%, and finally crushed, and the crushed material is sieved through a 20-60 mesh screen.

Embodiment 2

[0024] First remove the plastic bag film outside the discarded bacteria bag, and crush the bacteria group in it into pieces, then put it into the steam flash tank, feed steam to make the steam pressure rise to 0.15Mpa, and keep it for 25 minutes. Then the pressure was raised to 1.0Mpa, and immediately exhausted and decompressed to normal pressure; by weight, 15 parts of wheat bran, 5 parts of bacteria foot, 1.2 parts of urea, and 1.0 parts of ammonium sulfate were added to the 100 parts of bacteria block after flash evaporation 18 parts of rapeseed rice, 0.1 part of potassium dihydrogen phosphate, 0.05 part of magnesium sulfate, 10 parts of homemade yeast culture solution, 8 parts of Trichoderma culture solution and 40 parts of water, mix well, and cultivate at 30°C for 3 days; The protein feed additive obtained after mixed fermentation is dried until the water content is less than 12%, and finally crushed, and the crushed material is sieved through a 20-60 mesh screen.

Embodiment 3

[0026] First remove the plastic bag film outside the discarded bacteria bag, and crush the bacteria group into pieces, then put it into the steam flash tank, and feed steam to make the steam pressure rise to 0.25Mpa. After maintaining for 20 minutes, Then the pressure was raised to 0.6Mpa, and immediately exhausted and decompressed to normal pressure; by weight, 20 parts of wheat bran, 15 parts of bacterial foot, 1.5 parts of urea, and 1.5 parts of ammonium sulfate were added to the 100 parts of bacteria block after flash evaporation 20 parts of rapeseed rice, 0.2 parts of potassium dihydrogen phosphate, 0.05 parts of magnesium sulfate, 10 parts of homemade yeast culture solution, 10 parts of Trichoderma culture solution and 50 parts of water, mix well, and cultivate at 32°C for 3 days; The protein feed additive obtained after mixed fermentation is dried until the water content is less than 12%, and finally crushed, and the crushed material is sieved through a 20-60 mesh screen...

Abstract

The process of preparing protein feed additive with mushroom leftover includes crushing mushroom leftover with bag eliminated, fermentation and drying, and features the flash evaporation of crushed mushroom leftover before fermentation and the mixed microbial fermentation. The process can eliminate harmful metabolism product, toxin and pollutant microbe from mushroom leftover, crack and decompose cellulose in the material and form optimized protein and other nutritious components, and the protein feed additive can improve the taste and attraction of feed. The present invention may be used in treating various kinds of mushroom leftover to provide cheap concentrated feed while eliminating relevant environmental pollution.

Description

1. Technical field [0001] The invention belongs to the technical field of reuse of discarded fungus chaff after cultivation of edible fungi, and in particular relates to a method for making protein feed additives after treating the discarded fungus chaff after cultivation of edible fungi with microbial engineering technology. 2. Background technology [0002] The raw materials for the cultivation of edible fungi are mainly straw and cottonseed hulls. After one cultivation, about 30% of the cellulose in the raw materials is decomposed. Metabolites of cellulose, edible fungi, and more or less polluting microorganisms and their toxins. These cultivation wastes called fungus chaff are discarded randomly in the cultivation area because they are not reused and disposed of, which not only encroach on the land, but also cause serious pollution to the rural environment, endangering the healthy development of the edible fungus industry and the construction of a new countryside. [00...
