[0002] During the discharge process after fermentation, existing cell culture fermenters are prone to sedimentation at the bottom of the tank. Excessive sedimentation can easily cause blockages during discharge, and the discharge speed is relatively slow. Furthermore, it is not convenient to clean the tank in the later stages, as the bottom of the tank cannot be cleaned effectively.
[0003] Prior art CN209669246U discloses a cell culture fermenter, including a tank body and a top cover, which are interlocked. A stirring paddle is disposed through the upper part of the top cover. Stirring shafts are disposed on both sides of the bottom of the tank body, and small motors are disposed on both sides of the bottom of the tank body. The small motors are movably connected to the stirring shafts. A groove is formed on the front surface of the stirring paddle, and a fixing member is disposed at the front end of the groove. Several sets of mounting plates are fixedly installed on both sides of the stirring paddle. Stirring rods are fixedly installed on the upper and lower surfaces of the mounting plates. A support rod is disposed inside the stirring paddle. Furthermore, the front surface of the support rod is provided with several sets of positioning holes at equal intervals, and a brush is provided at the lower end of the support rod. A sight glass and a pH tester are provided on the front surface of the tank, with the pH tester located below the sight glass. A discharge port is provided at the center of the lower surface of the tank. By setting the support rod and the brush inside the agitator, the rotation of the agitator drives the support rod to rotate, which in turn drives the brush to rotate, thereby enabling the bottom of the tank to be brushed. This eliminates the trouble of manual brushing. After rinsing with water, the contents are discharged from the discharge port, thus completing the cleaning of the bottom of the tank and making the tank cleaning more convenient.
[0004] However, when using the above method, a lot of raw material will adhere to the inner surface of the tank during the discharge process after cell culture, resulting in incomplete discharge and thus reducing the productivity of cell culture. Utility Model Content
