Maintenance of fermentation tank

1 Maintain and maintain 1.1 precision filter, the general service life is one year If the filtration resistance is too large or the filtration capacity is lost, which will affect the normal production, it needs to be cleaned or replaced (it is recommended to replace directly without cleaning, because the performance of the filter cannot be guaranteed reliably after cleaning operation) 1.2 when cleaning the fermentation tank, please brush it with a soft bristle brush, and do not use a hard scraper to avoid damaging the surface of the fermentation tank 1.3 supporting instruments shall be calibrated once a year to ensure normal use 1.4 electrical equipment, such as electrical appliances, instruments, sensors, etc., shall not be directly in contact with water and steam to prevent moisture 1.5 when the equipment is out of service, it shall be cleaned in time, and the residual water in the fermentation tank and each pipeline shall be drained out; the tank cover and hand hole screws of the fermentation tank shall be loosened to prevent the deformation of the sealing ring 1.6 carbon steel equipment such as operation platform and constant temperature water tank shall be painted regularly (once a year) to prevent corrosion 1.7 check the oil level of the reducer frequently If the lubricating oil is not enough, increase it in time 1.8 replace lubricating oil of reducer regularly to extend its service life 1.9 if the fermentation tank is not used temporarily, it is necessary to empty the tank and drain the remaining water in the tank and each pipeline 2 Precautions 2.1 it must be ensured that the system can be used when all single equipment can operate normally 2.2 when sterilizing the filter, the steam pressure passing through the air filter shall not exceed 0.17mpa, otherwise the filter element of the filter will be damaged and lose the filtering ability 2.3 during the fermentation process, the tank pressure shall not exceed 0.17mpa 2.4 in the process of actual elimination, when the jacket is preheated by steam, the steam inlet pressure must be controlled within the working pressure range of the equipment (no more than 0.2MPa), otherwise the fermentation tank will be damaged 2.5 during air and solid digestion, make sure to drain the residual water in the fermentation tank jacket Otherwise, the cylinder in the fermentation tank may be flattened and the equipment may be damaged; during actual digestion, too much condensed water will be caused and the culture liquid will be diluted, so that the process requirements cannot be met 2.6 during the cooling process after air and solid elimination, it is strictly prohibited to generate negative pressure in the fermentation tank to avoid pollution or even damage to the equipment 2.7 during the fermentation process, the tank pressure shall be maintained between 0.03 and 0.05Mpa to avoid pollution 2.8 in each operation process, the pressure in the air pipe must be kept higher than the tank pressure of the fermentation tank, otherwise the liquid in the fermentation tank will flow back into the filter, block the filter element or make the filter invalid 2.9 if you encounter problems that you can't solve, please contact the after-sales service department of the company directly Do not remove or repair by force
