Embodiment 1
[0021] The process of utilizing biogas slag steam explosion technology of the present embodiment to produce mushroom nutrition bowl, the steps are as follows:
[0022] (1) Mix the fresh biogas residue with the air-dried manure powder at a ratio of 7:3, keep the water content of the raw material at about 40% after mixing, transport it to the steam explosion tank, and seal it and inject saturated steam;
[0023] (2) Keep the pressure of the steam explosion tank at 1.8MPa, the pressure holding time is 2 minutes, and then explode;
[0024] (3) The raw materials after blasting are transported to the mixing tank by screw conveyor in time, and then mixed with superphosphate, urea, lime powder, gypsum powder and calcium carbonate powder, each accounting for 1% of the total mass of biogas residue and manure powder, and adding Accounting for 1.5% of the total mass of biogas residue and manure powder, the moisture content is controlled at about 35%, and finally, pressed into shape; where...

Abstract
The invention discloses a technique for preparing a mushroom nutrition pot by a biogas residue steam explosion technique. The technique comprises the following steps: mixing fresh biogas residue and manure powder in a ratio of 7:3 (with the water content of 40%), sending the mixture into a steam explosion tank, and carrying out steam explosion treatment; after the raw materials are mixed, stamping in the steam explosion tank, and keeping the pressure at 1.8 MPa for 2-3 minutes; and mixing 1% of calcium superphosphate, 1% of urea, 1% of lime powder, 1% of gypsum powder and 1% of calcium carbonate into the raw materials subjected to steam explosion, adding 1.5% of adhesive, controlling the water content at 35% or so, and finally, carrying out pressure molding. The biogas residue has rich nutrients, and thus, has close nutrient content to the edible fungus culture medium; and the biogas residue has fewer infectious microbes, and is very suitable for the growth of edible fungi after being subjected to steam explosion. By using the biogas residue for culturing the edible fungi, the mushroom nutrition pot has the advantages of wide material sources, simple technique, low cost, high quality, high yield and the like, implements high value utilization of the biogas residue, and has obvious social benefits and economic benefits.
Description
technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a process for preparing mushroom nutritional bowls by utilizing biogas residue steam explosion technology. Background technique [0002] After decades of development, my country's biogas projects have begun to take shape. Up to now, a comprehensive development pattern of household biogas, small household biogas, small biogas projects, medium-sized biogas projects, large-scale biogas projects and extra-large biogas projects has been formed; and gas use, and gradually expand to the fields of various organic wastes in rural areas and industrial organic wastes. The use of biogas energy has also expanded from residential gas to power generation, vehicle gas, and chemical raw materials, showing a thriving situation. However, the utilization of biogas residues is not satisfactory, and the utilization value is generally low. If the planning is not proper, ...
