Problems solved by technology

Compared with other fermentation methods, the tunnel fermentation material has the advantages of uniform fermentation and precise control, but the current tunnel fermentation has problems such as large investment, high technical requirements, and large-scale machinery.
Most small factories and scientific research institutions can hardly afford the cost of fermentation tunnels and supporting equipment, and still carry out production and research in the way of natural stacking, which has many shortcomings such as uneven fermentation and the need for multiple turning operations, making small-scale, fine-grained The production of fermented cultivation materials and fermentation experiments for the purpose of chemical and scientific research are difficult to carry out normally

Abstract

The invention provides a small-sized fermentation box for an edible mushroom culture material. The small-sized fermentation box for the culture material comprises a fermentation box main body, a ventilation system and a control system, wherein the fermentation box main body comprises a heat preservation cover 10, an overpressure exhaust valve 11, a heat preservation box body 13, a grating plate 14, a fermentation chamber 12, a ventilation interlayer 17 and a drain valve 16; the ventilation system comprises a steam generator 1, a high-pressure fan 2, an air inlet pipeline 3, an air filter 4 and an air return pipeline 8; and the control system comprises a fresh air valve 5, a temperature sensor 6, an air return valve 7, an oxygen concentration sensor 9, an air pressure sensor 15, a steam valve 18 and a control box 19. Compared with existing fermentation equipment, the small-sized fermentation box for the edible mushroom culture material is miniaturized, integrated, low in cost and efficient, and can be used for carrying out small-scale and high-quality primary, secondary and tertiary fermentation on the culture material.

Description

technical field [0001] The invention belongs to the field of industrialized cultivation of edible fungi, in particular to a small fermentation tank for edible fungus culture material and its application. Background technique [0002] The current culture materials for edible fungi include clinker, fermented materials, raw materials, etc. Among them, wood rot fungi mainly use clinker for cultivation, and grass rot fungi mainly use fermented materials for cultivation. The existing fermented material production methods include natural fermentation, bed frame fermentation, tunnel fermentation and other methods, wherein farmers mainly use natural fermentation and bed frame fermentation, and large factories mainly use large tunnels for fermentation. Compared with other fermentation methods, the tunnel fermentation material has the advantages of uniform fermentation and precise control, but the current tunnel fermentation has problems such as large investment, high technical require...
