Technical field
The invention belongs to fungus growing technique field, be specifically related to a kind of technique utilizing biogas residue steam explosion technology to produce mushroom nutritive cube.
Background technology
Through the development of recent decades, the biogas engineering of China begins to take shape.By the end of at present, define the general layout that household biogas, small-sized joint household biogas, small-sized methane engineering, medium-sized biogas engineering, large-sized biogas engineering and super-huge biogas engineering are all-round developing；The application of biogas engineering, also by former solution rural environment with use gas problem, the progressively field extension such as various organic wastes, industrial organic wastes to rural area.The utilization of biogas energy also expands to marsh gas power generation, vehicle fuel and as industrial chemicals etc. by occupying domestic gas, presents thriving situation.But the utilization of biogas residue the most not only people's will, value is the most relatively low, as improper in planning, also can again result in secondary pollution problems.
Biogas residue is the semi-solid material after biogas fermentation, containing abundant machine matter, humic acid, crude protein, nitrogen, phosphorus, potassium and various trace elements etc., it is a kind of high-quality fertilizer having both slowly, is widely used in agricultural production at present, but for biogas engineering project itself, such utilization benefit is the best.And through anaerobic fermentation for biogas residue, pathogenic bacteria, viral level are the lowest, a kind of well cultivation matrix raw material, if the raw material of the nutritive cube for mushroom, miscellaneous mushroom can seldom, and mushroom yield can be greatly improved, and can reduce cost of material simultaneously.But biogas residue is difficult to organic matter and the microbial cells of new life quickly utilized containing some mushroom.
Summary of the invention
For problems of the prior art, the present invention provides a kind of process system utilizing biogas residue steam explosion technology to produce mushroom nutritive cube, solves biogas residue Utilizing question, it is achieved the higher value application of biomass resource.
For solve above-mentioned technical problem, the present invention by the following technical solutions:
A kind of technique utilizing biogas residue steam explosion technology to produce mushroom nutritive cube, step is as follows:
(1) batch mixing: the ratio of biogas residue with excrement powder 7:3 in mass ratio is mixed；
(2) steam explosion: mixed material is placed in steam-explosion jar, then passes to saturated vapor, uses the mode of punching press and pressurize to carry out steam explosion process；
(3) compounding: the raw material after steam explosion is blended into calcium superphosphate, carbamide, pulverized limestone, Gypsum Fibrosum powder and Paris white, is eventually adding binding agent, mix homogeneously；
(4) finished product: the material after Fu Pei uses compressing method to obtain finished product.
After described step (1) mixing, the moisture content of material is 35 ~ 45%.
Described step (2) punching press 1.75 ~ 1.85MPa in steam-explosion jar, pressurize 2-3min.
In described step (3), the addition of calcium superphosphate, carbamide, pulverized limestone, Gypsum Fibrosum powder and Paris white respectively accounts for the 1% of biogas residue and excrement powder gross mass, and the addition of binding agent accounts for the 1.5% of biogas residue and excrement powder gross mass.
Binding agent in described step (3) includes the raw material of following parts by weight: starch 45 parts, phosphate 15 parts, oxidant 0.13 part, coupling agent 0.11 part, 40 parts of water.
Described starch is cereal starch or potato starch；Described phosphate is disodium hydrogen phosphate；Described oxidant is the mixture of calcium hypochlorite and postassium hypochlorite, and wherein the mass ratio of calcium hypochlorite and postassium hypochlorite is 1:1；Described coupling agent is the mixture of furfural and methacrylic acid, and wherein the mass ratio of furfural and methacrylic acid is 1:1.
In described step (3), the moisture content of compounding rear material is 35 ~ 40%.
Beneficial effects of the present invention: biogas residue is nutritious, close with the nutrient content of culture medium of edible fungus, and miscellaneous bacteria is few, particularly after steam explosion, is very suitable for the growth of edible fungi.Biogas residue utilizes steam explosion technology, by High Temperature High Pressure, the harmful organism such as harmful bacteria in material, worm, worm's ovum, grass seed by rapid, thoroughly kill, and suppress pathogen again to grow；Low cost, effective, equipment are simple, take up an area less, with short production cycle, can reach the effect become thoroughly decomposed completely Yu have additional nutrients.Therefore, comprehensive utilization makes good use of the resource of this preciousness of biogas residue, and being possible not only to realization turns waste into wealth, reduces environmental pollution, promotes project structure adjustment, increase project income, and develops a circular economy especially, it is achieved the Important Action of low-carbon economy.
Through experimental study, the pretreated biogas residue of steam explosion, by the requirement of carbon-nitrogen ratio 30: 1, add the composition mushroom nutritive cubes such as excrement powder, calcium superphosphate, carbamide, pulverized limestone, Gypsum Fibrosum powder and Paris white, production cycle that nutritive cube become thoroughly decomposed can be greatly shortened, improve production efficiency, reduce production cost.Utilize biogas residue culturing edible fungus, have draw materials extensively, technology is simple, low cost, quality better, yield advantages of higher, it is achieved that the higher value application of biogas residue, its Social benefit and economic benefit is notable.
