Fermentation tanks are widely used in industrial production, and various experimental fermentation tanks and factory-scale production fermentation tanks are widely used in industrial production. These fermenter devices play an important role in biological fermentation. During the production process, the fermenter needs to continuously add and supplement various trace elements or catalysts in each process to control the properties of the fermentation process. The preciseness of the added trace elements can greatly affect the progress of the fermentation process and the quality of the final product.
Usually, the fermenter uses various pumps to automatically and continuously add liquid. During the entire fermentation process, the pump needs to continuously and stably supplement acid, acid, defoamer and medium. The whole conveying process requires sealing without pollution, simple maintenance, low shear force, and constant flow conveying; during the whole rehydration process, the flow rate needs to be adjustable, which can be adjusted from 0.1ml/min to 300ml/min; during the whole fermentation process, It is necessary to monitor the state of the entire fermentation process in real time to prevent the cells from losing activity during the cultivation process, and to meet the automatic control during the fermentation process. It is required that the pump and the tank control cabinet can be mechanically cooperated conveniently, and the embedded OEM form is required to cooperate with the control cabinet.Often in the process of biological fermentation, a peristaltic pump is selected as a tool for acid supplementation, alkali supplementation, defoaming, and fluid supplementation.
The peristaltic pump transmits the liquid by squeezing the hose during the working process. The liquid only contacts the hose. The whole pipeline is sealed without pollution, which can ensure the sterility requirements; the peristaltic pump has a low shear force, which is suitable for some cells and sensitive drugs. The liquid is not damaged, and it is easy to use and maintain.
The whole maintenance only needs to replace the corresponding hose. For other types of pumps, the working process will be in contact with the pump cavity, which cannot guarantee sterility, and the shear force is large, which will destroy the activity of the liquid medicine and make cleaning and maintenance more inconvenient. Compared with other pumps, peristaltic pumps are more suitable for the needs of biological fermentation.The manufacturability of the peristaltic pump is more advantageous than other pumps. According to customer needs, OEM embedded installation can be adopted, and the degree of cooperation with the customer's control cabinet is high.The peristaltic pump can be equipped with a servo control system. Compared with the traditional stepping motor and DC gear motor, the stability of the servo motor is better, and real-time monitoring and remote control can be realized. Customers can understand the working status of the peristaltic pump in real time through PLC, and understand the biological real-time The fermentation process is easy for customers to integrate and control. The servo motor can meet the characteristics of high torque, closed-loop control, low-speed stable operation, etc., and can meet the diversified needs of customers with different volumes of tanks.
01.During the transmission process of the peristaltic pump, only the pump tube is in contact with the raw liquid, and the hose is a consumable material, so the structure of the peristaltic pump needs to be easy to open and close, easy to install and remove the hose, and convenient for maintenance;
02.During the whole fermentation process, the peristaltic pump needs high flow repeatability, continuous and stable operation, adjustable speed, wide flow range, high torque, low speed operation, etc., so it can be controlled by servo system;
03.The peristaltic pump adopts embedded installation and will be presented in the form of OEM. The customer directly installs it on its control cabinet and realizes linkage control with its upper computer;
04.With functions such as feedback and temperature detection, it can solve the problems of overheating and out-of-step that customers worry about;
05.It supports a variety of remote control methods (4-20mA, 0-5V, Modbus 485 communication, etc.), which can be adapted to the customer's integrated system and help realize the integrated control of equipment.
