Inoculation equipment for biological fermentation and biological fermentation process

Abstract

The invention discloses inoculation equipment for biological fermentation and a biological fermentation process. The equipment comprises a box body and a fermentation tank, wherein the fermentation tank is positioned on the rear side of the box body; a partition plate is fixedly connected to the inner side of the box body, and a prefabrication cavity and an inoculation cavity are formed between the two sides of the partition plate and the two sides of the inner wall of the box body respectively; a culture box is slidably connected into the prefabricated cavity, and an inner box is inserted into the culture box; a separation cavity is formed between the bottom of the separation plate and the inner wall of the box body. Through the arrangement of the prefabricated cavity and the inoculation cavity, after microorganisms are cultured in the prefabricated cavity in advance, the microorganisms can directly act on the push-pull plate, so that the culture box containing the microorganisms can slide in the prefabricated cavity.The incubator is located in the prefabricated cavity, and in the process, microorganisms are transmitted from one independent space to another independent space; thereby, the contact time of microorganisms and the external environment is prevented from being too long, so that the probability that organisms are polluted by external bacteria is increased, operation is convenient, and the biological culture efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to an inoculation equipment for biological fermentation and a biological fermentation process. Background technique [0002] Biological fermentation engineering is an important part of biological engineering. Microorganisms use carbohydrates to ferment and produce various industrial solvents and chemical raw materials. In fermentation production, microbial seeds are first cultured in a sterile environment, and then inoculated into seed tanks through strains After cultivating for a period of time, the microbial seeds are cultivated in the seed tank to the peak production period and need to be transferred to the fermenter for fermentation and culture. [0003] At present, when cultivating microorganisms in the initial state, the seeds are cultivated in the seed tank after pre-cultivation, and the seed liquid in the seed tank is inoculated into the fermenter, and some a...

Problems solved by technology

[0003] At present, when cultivating microorganisms in the initial state, the seeds are cultivated in the seed tank after pre-cultivation, and the seed liquid in the seed tank is inoculated into the fermenter, and some are transported by the pressure difference method, that is, through the metal steel pipe. Connect the seed tank and the fermenter, then increase the pressure in the seed tank, and press the seeds in the seed tank into the fermenter, but when the pre-cultivated microorganisms are placed in the seed tank for re-culture, it is often necessary to put Take out the good organisms and put them into the next culture container, which will easily cause the pre-cultivated microorganisms to be in contact with the external environment for too long, increase the probability of the organisms being contaminated by external bacteria, and the operation is more troublesome, affecting the biological environment.
