Problems solved by technology

Obviously, the problems in the prior art are: 1) simply treating the fungus chaff as an additive for the secondary cultivation material cannot give full play to the potential value of the fungus chaff
Because the fungus chaff is used in conjunction with other cultivation materials after being dried in the sun, it is impossible to decompose about 70% of the remaining cellulose, and the nutrients contained in this part of the cellulose cannot be utilized; 2) the fungal chaff Treatment by drying can not eliminate the harmful metabolites and most of the polluting microorganisms contained therein, but will increase the amount of microbial contamination in the drying process, especially fungal spores and bacterial spores; 3) because the method used cannot remove bacteria Harmful metabolites in the bran and the proper decomposition of the remaining cellulose, it is actually difficult to use the fungus chaff as a cultivation base material again, otherwise it will affect the cultivation effect, therefore, the fungus chaff can only be used as an additive, and a small amount of it is added to the cultivation raw material , the secondary utilization rate is low; 4) Since the method used cannot remove the harmful metabolites in the fungus chaff, in order to avoid the influence of the harmful metabolites on the cultivation, it can only be used cross-use, which will undoubtedly reduce the scope of application of the secondary utilization

Embodiment 1

[0021]First, remove the plastic bag film outside the discarded fungus bag after one cultivation, and crush the fungus group in it into pieces, then put it into the steam flash tank, and feed steam to make the steam pressure rise to 0.1Mpa. After maintaining for 30 minutes, increase the pressure to 1.0Mpa, and immediately exhaust and depressurize to normal pressure, take out the bacteria block and dry it, and further crush it into fine pieces; by weight, 100 parts after flash drying Add 5 parts of microbial enzymes inoculated with Trichoderma and 60 parts of water to the bacterial block, mix well, and incubate at 30°C for 6 hours for microbial enzymolysis; add 20 parts of wheat bran to the bacterial block after microbial enzymatic hydrolysis, 0.05 1 part of potassium dihydrogen phosphate, 0.01 part of magnesium sulfate, 0.5 part of calcium sulfate, 0.001 part of zinc sulfate and 50 parts of water, mix well, and finally dry or sun-dry the compounded bacteria block until the moist...

Embodiment 2

[0024] First, remove the plastic bag film outside the discarded fungus bag after one cultivation, and crush the fungus 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 10 minutes, increase the pressure to 0.6Mpa, and immediately exhaust and depressurize to normal pressure, take out the bacteria block and dry it, and further crush it into fine pieces; by weight, 100 parts after flash drying Add 8 parts of microbial enzymes inoculated with Trichoderma and 80 parts of water to the bacterial block, mix well, and incubate at 32°C for 8 hours for microbial enzymolysis; add 15 parts of rice bran and 0.2 parts of Potassium dihydrogen phosphate, 0.05 parts of magnesium sulfate, 1 part of calcium sulfate, 0.002 parts of zinc sulfate and 50 parts of water are compounded, mixed well, put into a strain bottle, sterilized under steam 0.12Mpa for 30 minutes, take it out and let it cool , inoculated Flamm...

Embodiment 3

[0027] First, remove the plastic bag film outside the discarded fungus bag after one cultivation, and crush the fungus group in it into pieces, then put it into the steam flash tank, and feed steam to make the steam pressure rise to 0.2Mpa. After maintaining for 15 minutes, increase the pressure to 0.4Mpa, and immediately exhaust and depressurize to normal pressure, take out the bacteria block and dry it, and further crush it into fine pieces; by weight, 100 parts after flash drying Add 10 parts of microbial enzyme inoculated with Aspergillus oryzae and 100 parts of water to the bacterial block, mix well, and incubate at 35°C for 10 hours for microbial enzymolysis; add 5 parts of wheat bran to the bacterial block after microbial enzymatic hydrolysis, 0.1 1 part of potassium dihydrogen phosphate, 0.02 part of magnesium sulfate, 1 part of calcium sulfate, 0.004 part of zinc sulfate and 40 parts of water, mix well, put it into a strain bottle, sterilize it under steam 0.15Mpa for ...

Abstract

Disclosed is a method for preparing protein feedstuff addictive by utilizing edible fungus circulatory cultivation bran, which comprises steam flash evaporation, microorganism enzyme hydrolysis, multiple proportioning, cultivating edible mushrooms in circulation, reusing the discarded bacterium bran, crushing and carrying out micro-organism hybrid fermentation treatment. Calculated by weight ratio, each 100 parts of the bacterium block is charged by 21.58-58.25 parts of findings and 30-50 parts of water, then is inoculated with 5-10 parts of saccharomycete and 5-10 parts of wood mildew for culturing 2-3 days at 28-32 deg. C.

Description

1. Technical field [0001] The invention belongs to the technical field of reuse of discarded fungus chaff after edible fungus cultivation, and specifically relates to a method of recycling edible fungus after being processed by debag crushing, steam flashing, microbial enzymatic hydrolysis, compounding and drying. The method of making protein feed additives after the discarded fungus chaff is treated with microbial engineering technology again. 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 enviro...
