The stainless steel fermentation tank can be equipped with controllers with different performance. The controller can complete basic functions, parameter input and display devices, which are used to input various parameters that control fermentation conditions and display the temperature of the culture medium in the tank during the fermentation process, as well as the measurement values of dissolved oxygen.

The electrode calibration device of stainless steel fermentation tank is used to calibrate the pH electrode and DO electrode, etc. The acid and alkali pump is used to add acid or alkali to the fermentation tank to adjust the pH in the culture solution, and the defoamer adding pump is used to add defoamer to the fermentation tank to eliminate excessive foam during fermentation. The stainless steel fermentation tank alarm light and buzzer button. When there is a malfunction in the circuit during the fermentation process, if the temperature or DO on the display screen is flashing, which exceeds the measured value of the machine, the alarm red light will light up and emit a "beep, beep..." sound.

When cleaning stainless steel fermentation tanks, please use a soft bristle brush to brush and do not scratch with a hard tool to avoid damage to the surface of the fermentation tank. The supporting instruments should be calibrated once a year to ensure normal use. Electrical equipment such as appliances, instruments, sensors, etc. are strictly prohibited from coming into direct contact with water and steam to prevent moisture. When the stainless steel fermentation tank is stopped from use, it should be cleaned in a timely manner and the remaining water in the fermentation tank and various pipelines should be drained; Loosen the fermentation tank cover and hand hole screws to prevent deformation of the sealing ring. Carbon steel equipment such as operating platforms and constant temperature water tanks should be painted regularly (once a year) to prevent rusting.

If the stainless steel fermentation tank is not in use temporarily, it is necessary to empty the tank and drain the remaining water in the tank and various pipelines. During empty and actual consumption, it is necessary to drain the remaining water in the fermentation tank jacket, otherwise it may cause the stainless steel fermentation tank cylinder to flatten and cause equipment damage; During actual digestion, it can also cause excessive condensate water to dilute the culture medium, making it unable to meet the process requirements. During the cooling process of the stainless steel fermentation tank after the completion of air and solid digestion, it is strictly prohibited to generate negative pressure inside the fermentation tank to avoid pollution and even damage to the equipment. During each operation process, the pressure in the air pipeline must be kept higher than the tank pressure of the fermentation tank, otherwise it may cause the liquid in the fermentation tank to flow back into the filter, block the filter element or make the filter ineffective.

The automatic or manual control button of stainless steel fermentation tank is used to determine whether the controller is under automatic control or manual control. Electrode connecting wires: connecting wires, connecting with pH and temperature electrodes respectively, and installing electrodes. Before sterilization, check each interface, whether the appearance of each pipeline is normal, and whether the steam outlet pipe is firm. Each valve should be checked by two people to see if it is closed. At least two people are required to be present during the sterilization of stainless steel fermentation tanks. One person is responsible for operating various valves, and the other person is responsible for observing and reporting various parameters. After confirming that each valve is in a closed state, open the inlet valve of the steam generator, start the steam generator, and the steam generator begins to automatically feed water. At this time, the drain valve at the bottom of the steam generator should be opened, and the rust should be removed as much as possible before closing the drain valve.
