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

[0018] First, remove the plastic bag film outside the waste bacteria bag, and crush the bacteria group into pieces, then put it into the steam flash tank, and let the steam pressure rise to 0.1Mpa. After maintaining for 30 minutes, Then increase the pressure to 1.0Mpa, and immediately exhaust and depressurize to normal pressure, take out the bacterial block for drying, and further crush it into fine blocks; by weight, add 5 to 100 parts of the bacterial block after flash drying. 20 parts of wheat bran and 0.05 part of potassium dihydrogen phosphate were added to the bacterial mass after microbial enzymatic hydrolysis. , 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 fungus until the moisture content is less than 12%, which can be used as edible fungus. Recycled cultivation material.

Embodiment 2

[0020] First, remove the plastic bag film outside the waste bacteria bag, and crush the bacteria group into pieces, then put it into the steam flash tank, and let the steam pressure rise to 0.3Mpa. After maintaining for 10 minutes, Then increase the pressure to 0.6Mpa, and immediately exhaust and depressurize it to normal pressure, take out the bacterial block for drying, and further crush it into fine blocks; by weight, add 8 to 100 parts of the bacterial block after flash drying. 15 parts of rice bran, 0.2 part of potassium dihydrogen phosphate, 15 parts of rice bran and 0.2 part of potassium dihydrogen phosphate were added to the bacterial mass after microbial enzymatic hydrolysis. Mix 0.05 part of magnesium sulfate, 1 part of calcium sulfate, 0.002 part of zinc sulfate and 50 parts of water, mix well, and finally dry or sun-dry the compounded fungus until the moisture content is less than 12%, which can be used as a cycle of edible fungi Cultivation material.

Embodiment 3

[0022] First, take off the plastic bag film outside the discarded bacterial bag, and crush the bacterial mass into pieces, then put it into the steam flash tank, and inject steam to make the steam pressure rise to 0.2Mpa. After maintaining for 15 minutes, Then increase the pressure to 0.4Mpa, and immediately exhaust and depressurize to normal pressure, take out the bacterial block and dry it, and further crush it into fine blocks; by weight, add 10 parts of the 100 parts of the bacterial block after flash drying. Mix well with 100 parts of water inoculated with Aspergillus oryzae microbial enzyme, and incubate at 35°C for 10 hours for microbial enzymatic hydrolysis; add 5 parts of wheat bran and 0.1 part of potassium dihydrogen phosphate to the bacterial mass after microbial enzymatic hydrolysis , 0.02 parts of magnesium sulfate, 1 part of calcium sulfate, 0.004 parts of zinc sulfate and 40 parts of water are compounded, mixed well, and finally the compounded fungus is dried or...

Abstract

The invention relates to a process for preparing cyclical cultivation material for edible mushroom by using waste mushroom bran, comprising: crushing waste bran and double crossing with other cultivation material and then drying, and the invention is characterized in that it comprises flash evaporation with steam, and bacterial enzymolysis before double crossing, for which harmful metabolite and toxin will be destroyed and removed, and the fiber of not disintegrated will bulk, fracture and disintegrate, which is good for disintegration and usage of nutrition in mushroom for edible mushroom in cultivation course. The invention can solve problem of environmental pollution in edible mushroom producing area and reduce cultivation cost and stabilize productivity, which will promote standardized production of edible mushroom.

Description

1. Technical field [0001] The invention belongs to the technical field of recycling waste mushroom chaff after edible mushroom cultivation, and particularly relates to a method for preparing a recycled edible mushroom cultivation material by treating the waste mushroom chaff after edible mushroom cultivation with microbial engineering technology. 2. Background technology [0002] The cultivation raw materials of edible fungi are mainly straws and cottonseed husks. After one cultivation, the cellulose in the raw materials is decomposed by about 30%. These easily decomposed and transformed substances have been absorbed and utilized by edible fungi during the cultivation process, and most of the residues are difficult to decompose. Cellulose, metabolites of edible fungi and more or less present contaminating microorganisms and their toxins. Since these cultivation wastes called mushroom chaff are not reused and disposed of, they are discarded at will in the cultivation area, wh...
