Full-automatic control multifunctional solid-state fermentation tank

Abstract

The invention discloses a full-automatic control multifunctional solid-state fermentation tank, comprising a round vertical fermentation tank main body and a fermentation control system, wherein a loading auger is arranged at one side of the upper end of the fermentation tank main body; multiple clapboards are arranged in the fermentation tank main body; a high-material-bed material level automatic control device is arranged in each fermentation layer; a sterile air distribution system is arranged in each fermentation layer and is connected with a sterile air generation tank positioned at the outer side of the fermentation tank main body; a main shaft is rotationally arranged in the fermentation tank main body; and the upper ends of the clapboards are provided with stirring blades. The full-automatic control multifunctional solid-state fermentation tank disclosed by the invention integrates eight functions including dry material mixing, watering material mixing, steam sterilization, inoculation, automatic fermentation control, low-temperature drying, raw material crushing, automatic discharging and finished product smashing, and enables all operations of solid-state fermentation to be completed in a multifunctional biological solid-state fermentation tank; and by virtue of the equipment disclosed by the invention, the fermentation and production preparation processes of solid biological products can be continuously completed.

Description

technical field [0001] The invention relates to a vertical full-automatic solid-state continuous fermentation equipment, in particular to a fully-automatically controlled multifunctional solid-state fermentation tank. Background technique [0002] There are two main fermentation methods in industrial production: submerged liquid fermentation and solid-state fermentation. Among them, the submerged liquid fermentation method is the most important fermentation process, the technology is relatively mature, and it is widely used in industrial production. However, there are also disadvantages such as complex technological process, easy bacterial contamination, complex post-fermentation treatment, large discharge of three wastes, and low spore production rate. With the development of the times, the further development of liquid submerged fermentation technology has encountered obstacles. High pollution and high energy consumption are the biggest problems it faces. High-concentrati...

AI Technical Summary

Problems solved by technology

Among them, the substrate in the dynamic solid-state fermentation bioreactor is in an intermittent or continuous motion state, which enhances heat transfer and mass transfer. The equipment structure is relatively compact and the degree of automation is relatively high. Most of them are within 100m 3 Below, due to unreasonable structure, zoom in to 200 m 3 There are a series of problems such as uneven fermentation process, difficulty in discharging materials, bacterial contamination, and process inspection and control. So far, there have been no reports on large-scale industrial-scale solid-state reactors.
