Method for manufacturing edible fungus spawn by using polyurethane sponge as spawn carriers

Abstract

The invention discloses a method for manufacturing edible fungus spawn by using polyurethane sponge as spawn carriers. The method comprises the following steps that firstly, corn flour and wheat flour are mixed, water is added to the mixed flour, paste is formed in a boiled mode, and the paste is cooled for standby application; secondly, the sponge is placed in the paste and stirred repeatedly, so that the paste permeates into holes of the sponge, then the sponge is pulled out, superfluous paste is squeezed, the sponge is placed in dry bran to be stirred and rolled over, and the bran adheres to the surfaces of the sponge; thirdly, the sponge with the bran in an adhering mode is placed in double-layer polypropylene bags uniformly, the surfaces are covered with fine wood chips, and sealing is conducted; fourthly, sterilization is conducted, inoculation is conducted after cooling, and cultivation is conducted. The method for manufacturing the edible fungus spawn is conducted by using the polyurethane sponge as the spawn carriers, the finished spawn is attached to the sponge after being cultivated, and the finished spawn can be processed into any physical shapes in an industrial and standardized mode; the finished spawn is attached to the sponge carriers, the finished spawn is easily separated from the sponge in a using process and is easily scattered in a pounded mode, and it can be avoided that the vitality of the spawn is damaged in an inoculation process because the spawn is bounded to pieces.

Description

technical field [0001] The invention relates to a method for preparing a strain for edible fungus production, in particular to a method for preparing an edible fungus strain using a polyurethane sponge as a strain carrier. Background technique [0002] Edible fungus strains are the seeds produced by edible fungi and are the starting point of edible fungus production. Selecting different materials to make edible fungus strains relates to the vitality, quantity and use and preservation performance of the strains. The invention utilizes sponge and some grain raw materials to produce edible fungus strains, which not only simplifies the seed production operation, but also greatly improves the use performance of the strains, widens the production area of ​​the strains, and improves work efficiency. [0003] At present, there are two kinds of solid edible fungus strains according to the material. One is to add a small amount of grain to the theme of wood and forage, and the other ...

Problems solved by technology

[0004] Traditional edible fungus strains use biomass as the material, and the strains are made after simple treatment or processing. The physical form of the strains is basically restricted by the natural properties of the material, or requires high processing costs to meet the use requirements.

Moreover, the finished strains are inconvenient to operate during use, and the inoculum volume cannot be uniform, so it is difficult to achieve standardization and standardization. During the inoculation process, the strains will be damaged due to smashing the strains, and at the same time The production process is time-consuming and expensive
