Rotary shaft type solid state fermentation tank

Abstract

The utility model discloses a rotary shaft type solid state fermentation tank, which comprises a fermentation tank body, a support, a rotary stirring mass transfer heat transfer device and a driving device. The fermentation tank body and the rotary stirring mass transfer heat transfer device are both fixed on the support, and the rotary stirring mass transfer heat transfer device is driven by the driving device. In a fermentation process of the rotary shaft type solid state fermentation tank, water can be replenished in the solid state fermentation tank in atomization mode, moisture is even, and humidity control accuracy is high. A clamp sleeve is arranged outside the fermentation tank, and a stirring shaft and a stirring paddle are positioned inside the fermentation. Steam or cooling water can circularly flow in the clamp sleeve, the stirring shaft and the stirring paddle. With appropriate stirring, solid media can be fully in contact with spawn, heat in the solid media is quickened to be radiated, heat exchange efficiency is improved under the venting condition, and temperature control accuracy is high. Simultaneously, in-site sterilization of the solid media is achieved, the media after off-site sterilization are prevented from contacting external environment when moved into the solid state fermentation tank, and requirements for environment are reduced. The fermentation tank can be installed laboratories or workshops in non-purification areas, thereby avoiding configuring media sterilization equipment and achieving an effect of saving investment.

Description

technical field [0001] The invention belongs to the technical field of bioreactors, and in particular relates to a shaft-type solid-state fermenter. Background technique [0002] At present, according to the different physical properties of the medium in the fermentation process, the fermentation methods are divided into two categories: liquid fermentation and solid-state fermentation. The traditional solid-state fermentation technology originated in China and has a history of thousands of years ago. Its fermentation technology is relatively extensive and does not require strict aseptic conditions. Can be fermented. Compared with traditional solid-state fermentation, modern solid-state fermentation has undergone great changes, and it can realize the intensive cultivation of pure species of defined microorganisms. Modern fermentation is carried out in a solid-state fermenter with a closed container, which requires aseptic treatment of fermentation raw materials, and a singl...
