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...

Embodiment Construction

[0051] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0052] like Figure 1 to Figure 3 As shown, the present invention provides a microbial solid-state culture system, which includes a microbial solid-state culture device 100 and a fluid source 200. An inlet pipe 120 communicates with the fluid source 200, wherein the microbial solid-state culture device also includes a sieve plate 140 with sieve holes, the sieve plate 140 is arranged in the box body 110, and divides the inner space of the box body 110 into upper and lower layers , the first inlet pipe 120 communicates with the lower layer of the box body 110 , and the outlet pipe 130 communicates the box body 110 with the outside.
