Microorganism fermentation device

Abstract

The invention provides a microorganism fermentation device. The device comprises a fermentation cylinder and a stirring unit. The fermentation cylinder is made of a transparent glass bottle with a feeding port formed in the upper portion and a discharging port formed in the lower portion. A seal cover is arranged at the feeding port and the discharging port respectively. A PH meter is arranged in the cylinder. The stirring unit comprises an air inlet guide tube and an air outlet guide tube. A hollow propeller is connected with the lower end of the air inlet guide tube, air holes communicated with the air inlet guide tube are distributed in blades, an air filter and a micro pore filtering membrane are arranged on the air inlet guide tube and the air outlet guide tube respectively, and the air inlet guide tube and an air outlet guide tube are connected with a cylinder opening of the fermentation cylinder. The device has the advantages of being simple in structure, low in cost, detachable, convenient to clean, wide in application range and the like.

Description

technical field [0001] The invention relates to a microbial fermentation device, in particular to a small liquid microbial fermentation device. Background technique [0002] Microbial fermentation is an intricate process, and the fermentation device is the most important and widely used equipment among the commonly used equipment in fermentation engineering. [0003] The fermentation device provides a good environment for the growth and metabolism of one or more microorganisms. The fermentation device has a history of hundreds of years with the development of the microbial fermentation industry. Modern fermentation devices require high equipment rigor and reliability. Sexuality has become a notable feature of fermentation industrial equipment. In order to obtain greater economic benefits, the modern fermentation industry tends to develop in the direction of large-scale and automation. Existing fermentation devices such as ventilated stirring fermenters and air-lift ferment...

AI Technical Summary

Problems solved by technology

Existing fermentation devices such as ventilated stirring fermenters and air-lift fermenters are prominent in industrialization, and the entire device of the fermentation equipment and its auxiliary equipment is too large, which takes up a lot of space, wastes consumables, and the cost of equipment is too high, so it is not suitable for fermentation. The initial test and it is not conducive to small-scale fermentation. Although it can easily realize continuous fermentation, it is not conducive to disassembly and washing, and it is not suitable for disinfection and sterilization. The cycle of completing a fermentation is longer than expected
