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 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 0.1Mpa. After maintaining for 30 minutes, Then the pressure is raised to 1.0Mpa, and immediately exhausted and decompressed to normal pressure, the bacteria block is taken out and dried, and further crushed into fine pieces; by weight, add 5 1 part of microbial enzyme inoculated with Trichoderma and 60 parts of water were mixed well, and kept at 30°C for 6 hours for microbial enzymolysis; 20 parts of wheat bran and 0.05 part of potassium dihydrogen phosphate were added to the bacterial block 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 bacteria block until the water content is less than 12%, which can be used as edible ...

Embodiment 2

[0020] 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 10 minutes, Then the pressure is raised to 0.6Mpa, and immediately exhausted and decompressed to normal pressure, the bacteria block is taken out and dried, and further crushed into fine pieces; by weight, add 8 1 part of microbial enzyme inoculated with Trichoderma and 80 parts of water were mixed well, and incubated at 32°C for 8 hours for microbial enzymolysis; 15 parts of rice bran and 0.2 part of potassium dihydrogen phosphate were added to the bacterial block after microbial enzymolysis, Mix 0.05 parts of magnesium sulfate, 1 part of calcium sulfate, 0.002 parts of zinc sulfate and 50 parts of water, mix well, and finally dry or sun-dry the compounded bacteria blocks until the moisture content is less than 12%, then they can be used as ed...

Embodiment 3

[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 0.2Mpa. After maintaining for 15 minutes, Then the pressure is raised to 0.4Mpa, and immediately exhausted and decompressed to normal pressure, the bacteria block is taken out and dried, and further crushed into fine pieces; by weight, add 10 Mix 100 parts of microbial enzyme inoculated with Aspergillus oryzae and 100 parts of water, and incubate at 35°C for 10 hours for microbial enzymolysis; add 5 parts of wheat bran and 0.1 part of potassium dihydrogen phosphate to the bacterial block after microbial enzymolysis , 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 bacteria block is dried or dried until the water content is less than 12%, which can be used as ...

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 reuse of discarded mushroom chaff after cultivation of edible fungi, and in particular relates to a method for making recycled edible fungus cultivation material after treating the discarded mushroom 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 land occupation, but also cause serious pollution to the rural environment, endangering the healthy development of the edible fungus industry and the construct...
