Centralized secondary fermentation method for agaricus bisporus

Abstract

The invention discloses a centralized secondary fermentation method for agaricus bisporus. The culture medium comprises the following raw materials in parts by weight: 45-60 parts of forage, 35-50 parts of chicken manure, 2-8 parts of gypsum and 3-10 parts of oil cakes. The method comprises the following steps of: uniformly spreading forage in a pre-wetting pool for pre-wetting for 2-5 days; adding chicken manure, gypsum and oil cakes and uniformly and adequately mixing; filling the mixed fermentation material in a ventilating floor in a primary fermentation tunnel, and conveying fresh air to the fermentation material through a fan; fermenting for 4-6 days and transferring the fermentation material to another primary fermentation tunnel. The base material of the primary tunnel fermentation is uniformly stacked on the ventilating floor in a secondary fermentation tunnel, and the temperature of the fermentation material is controlled by operation of the fan. Secondary fermentation comprises the following steps: a balancing stage, a heating stage, pasteurization, cultivation at constant temperature and discharge at low temperature. According to the method, local wheat straw hoods, straws, chicken manure and the like are used as main raw materials to form the culture medium. Centralized scaled production cultivation materials are formed by the technology of pre-treatment of the raw materials, primary fermentation and secondary fermentation.

Description

technical field

[0001] The invention relates to edible fungi, in particular to a method for fermenting Agaricus bisporus. Background technique

[0002] Agaricus bisporus is the most widely cultivated edible fungus with the largest output and consumption in the world. It uses the waste of farming industry as the production substrate, and its fruiting body is rich in protein. At present, domestic mushroom production is mostly a simple cultivation method, with simple facilities, backward technology, small scale, low output, poor quality, unreasonable formula nutrient distribution, irregular operation, and pre-fermentation of compost (equivalent to a tunnel) Fermentation) Affected by the external climate (temperature, rain, strong wind, etc.), the fermentation is uneven, and the post-fermentation (equivalent to the second tunnel fermentation) pasteurization and temperature maintenance are not in place, resulting in poor maturity of the culture material, miscellaneous bacteria, i...

Embodiment 1

[0042] 1. Primary fermentation

[0043] 1.1 Material preparation

[0044] The raw material of the culture medium is prepared by mixing the following ingredients: 45 tons of wheat straw, 5 tons of straw, 40 tons of chicken manure, 4 tons of gypsum, and 6 tons of oil.

[0045] Forage: According to the fermentation process, the length of wheat straw is not required, and the length of straw is 20cm-30cm, and the straw is processed by a mower. It is required that wheat straw and rice straw have no mildew and a moisture content of 15%-18%.

[0046] Chicken manure: The newly transported chicken manure is fully stirred in the manure storage tank and left for more than 7 days to allow it to degrade naturally. Nitrogen content in wet chicken manure (dry sample nitrogen content above 3.5%), ash content below 28%, water content 80-85%.

[0047] Gypsum powder: non-crystalline calcium sulfate, with a purity of over 98% and a fineness of over 100 mesh.
