Secondary fermentation tunnel device for agaricus bisporus compost

Abstract

The invention discloses a secondary fermentation tunnel device for agaricus bisporus compost. The secondary fermentation tunnel device comprises a closed tunnel cabin body composed of a fermentation tunnel top, a tunnel wall body and a high pressure air-injection ground, wherein the fermentation tunnel top is formed by sequentially attaching a waterproof layer, a slag cushion layer, a benzene plate insulation layer and a concrete layer; the tunnel wall body comprises a rear tunnel wall and side tunnel walls; the rear tunnel wall and the side tunnel walls are respectively formed by sequentially attaching a concrete placing layer, a benzene plate insulation layer and a brick laying layer; ventilation and exhaust duct systems formed by return air inlets and air inlets are arranged in the rear tunnel wall; the high pressure air-injection ground is formed by sequentially attaching a concrete layer, an insulation layer and a slag cushion layer; and a pipeline system for high-speed circulation of hot air, which is formed by a high pressure air nozzle and a ventilation pipe, is embedded in the concrete layer. The technical problem brought by steam which is introduced by using a secondary fermentation tunnel of mushroom composts is solved, the secondary fermentation effect of the mushroom compost is good in an environment with the temperature being 28 degrees below zero when the steam is not used, and the mushroom yield can reach 25-30 kg per square meter.

Description

technical field [0001] The invention relates to the technical field of equipment for the fermentation process of mushroom compost, in particular to the technical field of a secondary fermentation tunnel device for bisporus compost. Background technique [0002] At present, the mushroom compost secondary fermentation tunnel has two functions in the actual mushroom compost secondary fermentation process: one is to remove all mushroom diseases and pest sources that affect the growth of mushrooms in the mushroom compost. The second is to further carry out mesophilic controlled fermentation of mushroom culture through air conditioning. Through the two-stage process of secondary fermentation, the mushroom compost is transformed into a mushroom compost that is highly selective for mushroom growth, that is, it is only suitable for the growth of mushrooms and not suitable for the growth and breeding of other organisms that are unfavorable to the growth of mushrooms. Since the 1960s,...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at introducing steam into the fermentation tunnel in the secondary fermentation process in the existing edible fungus culture, in order to increase the temperature in the fermentation tunnel to achieve the purpose of pasteurization, resulting in many technical defects, the present invention aims to overcome and solve the existing edible fungi. In order to solve the technical problem of introducing steam into the fermentation tunnel in the early stage of the secondary fermentation process in bacterial culture, a secondary fermentation tunnel device for Agaricus bisporus compost is designed to fully utilize and protect the heat generated by the fermentation temperature of the mushroom compost during the fermentation process. In the fermentation tunnel, a secondary fermentation tunnel that does not use steam for pasteurization is designed and built to increase the overall temperature of the secondary fermentation tunnel for mushroom compost, thus overcoming the technical problems caused by the introduction of steam into the fermentation tunnel commonly used in the industry and achieving good technical effect
