Microorganism solid-state culture system

Abstract

The invention discloses a microorganism solid-state culture system. The microorganism solid-state culture system comprises a microorganism solid-state culture device (100) and a fluid source (200), wherein the microorganism solid-state culture device comprises a box body (110), a first inlet pipe (120) and a discharge pipe (130); the first inlet pipe (120) is communicated with the fluid source (200); the microorganism solid-state culture device further comprises a sieve plate (140) with sieve meshes; the sieve plate (140) is arranged in the box body (110) and divides the internal space of the box body (110) into upper and lower layers; the first inlet pipe (120) is communicated with the lower layer of the box body (110); the box body (110) is communicated with the outside via the discharge pipe (130). Since the sieve plate is arranged at the bottom of the box body, sterile air or water vapor is introduced from the box body at the bottom of the system and rises up and passes through materials stacked on the sieve plate, so that temperature difference and humidity difference between the upper and lower layers of the materials are relatively small.

Description

technical field [0001] The invention relates to microorganism cultivation equipment, in particular to a microorganism solid-state cultivation system. Background technique [0002] Solid-state fermentation is one of the technologies with the longest history for humans to use microorganisms to produce products. The brewing industry with a long history in my country is a typical representative of solid-state fermentation. Solid-state fermentation contains water-insoluble solids, a small amount of water and air. The heat generated by microorganisms causes water to evaporate, making the fermentation system have a three-phase inhomogeneous vapor-liquid-solid, with serious concentration gradients and difficulties in heat and mass transfer. It is difficult to control pH, water activity, optimal reaction temperature, etc., which greatly reduces the yield, especially the first condition of modern fermentation technology is purebred cultivation, which does not allow other microorganism...

AI Technical Summary

Problems solved by technology

However, in this automatic rotary microbial spore incubator, the material is piled up at the bottom of the incubator, which makes the gradient difference of temperature and humidity between the upper and lower layers of the material layer large, which is not conducive to the growth of microbial spores.
