A fermenter is a device used for microbial fermentation to improve fermentation efficiency by optimizing the fermentation conditions of the microorganism. According to the aerobic and anaerobic properties of the cultured microorganisms, the fermenters can be classified into aerobic and anaerobic types. Fermenters generally have good liquid mixing capacity, heat transfer rate, and reliable detection and control instruments.
Fermentation tank is a kind of reaction equipment, which is the main equipment in chemical reaction in chemical production, and a kind of equipment for mechanical stirring and fermentation of materials. The main functions of the fermenter are:
1. The gas is well dispersed in the liquid phase;
2. Mix the materials evenly;
3. uniformly suspending or fully emulsifying another liquid phase which is uneven;
4. The solid particles are uniformly suspended in the liquid phase;
5. Strengthen heat transfer.
6. Strengthen the mass transfer between phases;
Fermenters are currently widely used in pharmaceutical, enzyme, MSG, food industries, and the like. Its main components include the kettle body, heat transfer device, stirring device and shaft sealing device. Also add other accessories as needed, such as welding manholes, hand holes and various interfaces for easy access to internals and feeding and discharging, installing thermometers, sight glasses, pressure gauges, for effective monitoring and control during operation. Safety relief device for temperature and pressure of materials. The kettle body is generally composed of a simplified body and two heads, and its function is to provide a certain space for the chemical reaction of the materials. The stirring device is composed of a transmission device, a stirring shaft and a stirrer, and the function is to uniformly mix various materials participating in the reaction, so that the materials are in good contact and accelerate the progress of the chemical reaction.
The heat transfer device of the fermenter is provided with a coil inside the kettle body or a jacket outside the kettle body, so as to control the temperature of the material within the range required for the reaction. The shaft sealing device is a seal between the stirring tank and the stirring shaft to prevent the escape of the reaction material and the infiltration of impurities. Filler seals or mechanical seals are usually used.
