Microbial fermentation reactor

Abstract

The invention relates to the technical field of biological fermentation, in particular to a microbial fermentation reactor which comprises a reactor body, a transmission mechanism is fixedly arranged in the center of the bottom end of the reactor body, a sealing plate is slidably arranged in the inner wall of the top of the reactor body in a sleeved way, and a stirring mechanism is fixedly connected to the center of the top of the sealing plate. The bottom of the sealing plate is fixedly connected with a gas transmission mechanism, the outer wall of the left side of the reactor body is provided with an auxiliary mechanism, the top end of the sealing plate is provided with a feeding port, the upper end of the feeding port is in threaded connection with a sealing cover, the bottom end of the reactor body is provided with a discharging pipe, the discharging pipe is provided with a switch valve, and the sealing plate is fixedly connected with an air cylinder. The stirring mechanism and the transmission mechanism are arranged in a matched manner, so that a stirring rod and the reactor body can rotate in different directions, and the stirring effect is improved; and the auxiliary mechanism and the gas transmission mechanism are arranged in a matched manner, so that when microorganisms need aerobic fermentation, oxygen can be added into the reactor body, and the practicability of the microbial fermentation reactor is improved.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a microbial fermentation reactor. Background technique [0002] Fermentation tank refers to a device used in industry for microbial fermentation. Its main body is generally a main cylinder made of stainless steel plate, with a volume of 1m 3 to hundreds of m 3 , in the design and processing should pay attention to the structure is tight, reasonable, can withstand steam sterilization, have a certain operating flexibility, minimize the number of internal accessories (to avoid dead ends), strong material and energy transfer performance, and can be adjusted to facilitate cleaning, Reduce pollution, suitable for the production of various products and reduce energy consumption. Fermentation tanks used for aerobic fermentation (such as the production of antibiotics, amino acids, organic acids, vitamins, etc.) need to continuously feed a large amount of sterile air into...

AI Technical Summary

Problems solved by technology

[0004] During use, it was found that there were the following problems: the existing microbial fermentation reactor generally uses a motor to drive the internal stirring paddle of the fermenter, and continuously stirs during the fermentation process to achieve the purpose of full fermentation. This stirring method cannot fully Stirring the raw materials in the tank makes the fermentation insufficient, and the stirring and mixing efficiency is low; most of the existing microbial fermentation reactors are connected to the air intake pipe at the top, and this air intake method is used to transport oxygen into the reactor, and the material at the bottom of the reactor is received less oxygen, resulting in poor fermentation effect; most of the existing microbial fermentation reactor shells are fixed structures, which cannot be applied to a variety of different use environments, and have low practicability
