What are the technological requirements of fermentor?

According to the equipment of fermenters, fermenters are mainly used in China, which are divided into mechanical stirring aeration fermenters and non-mechanical stirring aeration fermenters. According to the needs of microbial growth and metabolism, it can be divided into aerobic fermentor and anaerobic fermentor.

The structure of the fermentor used for anaerobic fermentation (such as producing alcohol and solvent) can be relatively simple. The requirements for this fermentor are: it can be sealed; Able to withstand certain pressure; Have cooling equipment; Minimize the number of equipment in the tank, eliminate dead corners and facilitate cleaning and disinfection. Both alcohol and beer belong to anaerobic fermentation products, and their fermentors do not need expensive sterile air, so the equipment amplification, manufacture and operation are much simpler than aerobic fermentation equipment.

Fermentation tank is used for aerobic fermentation (such as producing antibiotics, organic acids, vitamins, etc.). ) It is necessary to continuously introduce a large amount of sterile air into the tank, but in order to consider the utilization rate of the introduced air, the structure of the fermenter is complicated, and commonly used fermenters include mechanical stirring fermenter, bubbling fermenter and airlift fermenter.

The fermentor adopts internal circulation mode, and the bubbles are dispersed and broken by stirring paddles. High dissolved oxygen rate and good mixing effect. The tank is made of imported stainless steel SUS304 or 3 16L, and the tank is equipped with automatic spray cleaning head to ensure that the production process meets GMP requirements. Fermentation tanks are widely used in dairy products, beverages, bioengineering, pharmaceuticals, fine chemicals and other industries. In recent years, with the continuous progress of science and technology, the fermentation industry related to the national economy and people's livelihood has made rapid development, and the fermentation equipment has also been updated from tradition to modernization.

The main body of fermentation tank has the functions of interlayer, thermal insulation layer, heating, cooling and thermal insulation. The tank body and the upper and lower elliptical heads (or prototypes) are all processed by spinning R-angle, and the inner wall of the tank is mirror polished, which is sanitary and has no dead ends. Fully enclosed design ensures that materials are always mixed and fermented in a pollution-free state (at the entrance and exit). The equipment is equipped with air breathing holes, CIP cleaning nozzles, manholes, entrances and exits and other devices.

Fermentation tanks are widely used in dairy products fermentation, beer fermentation, wine fermentation, kitchen waste treatment equipment, food wastewater treatment equipment, beer wastewater treatment equipment, biogas fermentation equipment and other fields.

Fermentation tank is the core equipment that provides a good reaction environment for microbial fermentation, cell culture and enzyme reaction to complete biocatalytic reaction. It is usually called bioreactor or multi-enzyme reactor and undertakes the production task of products.

The structure, operation mode and operation conditions of fermentation tank are closely related to the quality, conversion rate and energy consumption of biological process products. An excellent culture device should have a compact structure, good liquid mixing performance, high heat transfer rate and a reliable detection and control system.

The only criterion for testing fermentation equipment should be whether the equipment can meet the technological requirements in order to obtain new production benefits.
