Structure and Precautions for Using Fermentation Tanks

1.1 Fine filters typically have a service life of one year. If the filtration resistance is too high or the filtering capacity is lost, affecting normal production, they need to be cleaned or replaced (it is recommended to replace directly, rather than clean, as cleaning operations cannot reliably guarantee the functionality of the filter).

1.2 When cleaning the fermentation tank, please use a soft brush for rinsing, and do not use hard tools to scrape, to avoid damaging the surface of the fermentation tank.

1.3 Supporting instruments should be calibrated once a year to ensure normal use.

1.4 Electrical equipment such as electrical appliances, instruments, and sensors must not come into direct contact with water or steam to avoid moisture.

1.5 When the equipment is not in use, it should be cleaned promptly, and residual water in the fermentation tank and various pipelines should be drained; loosen the fermentation tank lid and manhole screws to avoid permanent deformation of the sealing ring.

1.6 Carbon steel equipment such as operating channels and constant temperature water tanks should be painted regularly (once a year) to prevent rust.

1.7 If the fermentation tank is temporarily not in use, it should be emptied and residual water in the tank and various pipelines should be drained.

2. Precautions

2.1 It is necessary to ensure that all individual pieces of equipment can operate normally when using this system.

2.2 When disinfecting the filter, the steam pressure passing through the air filter must not exceed 0.17MPa, otherwise the filter element will be damaged and lose its filtering capacity.

2.3 During the fermentation process, the tank pressure should not exceed 0.17MPa.

2.4 During the actual disinfection process, when preheating the jacket with steam, it is necessary to control the inlet steam pressure within the working pressure range of the equipment (should not exceed 0.2MPa), otherwise it may cause damage to the fermentation tank.

2.5 During emptying and actual disinfection, it is essential to drain the residual water in the jacket of the fermentation tank. Otherwise, it may cause the inner cylinder of the fermentation tank to be crushed, resulting in equipment damage; during actual disinfection, excessive condensate may dilute the culture solution, making it unable to meet technical requirements.

2.6 After the emptying and actual disinfection, during the cooling process, negative pressure must not occur inside the fermentation tank to avoid contamination or even damage to the equipment.

2.7 During the fermentation process, the tank pressure should be maintained between 0.03 and 0.05MPa to avoid contamination.

2.8 During various operational processes, it is necessary to maintain the pressure in the air pipeline greater than the tank pressure of the fermentation tank, otherwise it may cause the liquid in the fermentation tank to flow back into the filter, blocking the filter element or rendering the filter ineffective.

2.9 If you encounter problems that you cannot solve yourself, please contact the company's after-sales service department directly. Do not forcibly disassemble or repair.
