Solid state fermentation device

Abstract

The invention discloses a material fermentation device, and in particular relates to a solid state fermentation device, which comprises a fermentation box body, wherein a feeding port is arranged above the fermentation box, a discharging port is arranged below the fermentation box body, the fermentation box body is internally provided with more than two layers of parallel devices as well as staggered fermentation beds capable of undertaking materials falling off from an upper layer, a drive mechanism is arranged outside the fermentation box body, a spiral conveying device is arranged above the feeding port and is internally provided with spiral conveying blades, the fermentation box body is internally provided with more than one blank baffle which is respectively arranged between two adjacent fermentation beds, and a discharging baffle is arranged at the bottom of one side of the fermentation box body. Due to the adoption of the structure, the spiral conveying blades are used for conveying so that the material can be kept in a certain dispersing degree, therefore, the material is guaranteed to be uniform, zigzag teeth are arranged so as to enable the material to be better dispersed, an access door is arranged on the fermentation box body, and an inspection window arranged on the access door is convenient to overhaul the fermentation bed.

Description

[0001] technical field [0002] The invention relates to a material fermentation device, in particular to a solid-state fermentation device, which belongs to the technical field of biological fermentation devices. Background technique [0003] Solid fermentation refers to a biological reaction process in which a certain amount of oxygen is introduced into a water-insoluble substrate with a certain humidity in the state of no or almost no free-flowing water, and one or more microorganisms are used. In recent years, with the development of bioengineering high-tech industry, the traditional brewing technology of solid fermentation has received more extensive attention and new understanding. Compared with other cultivation methods, solid fermentation has the following basic characteristics: low equipment energy consumption, high output yield, no "three wastes" discharge, and easy for production enterprises to realize clean production processes.

AI Technical Summary

Problems solved by technology

[0004] Traditional solid material fermentation mostly adopts rotating shaft or drum type fermentation devices, through the rotation of the screw stirring blade or drum, the materials are mixed, sterilized, cooled, inoculated, and fermented, but when the above devices are used for fermentation, due to the material Uneven turning makes it difficult to uniformly control the fermentation temperature, humidity, pH value and other parameters of the material. The oxygen supply of the material is insufficient, the energy consumption is high, the fermentation time is long, the fermentation yield is low, and continuous fermentation cannot be realized.
