1、 Maintenance

1.1、In general, the service life of precision filter is half a year. If the filtration resistance is too large or losing the ability to filter that affects the normal production, you need to clean or replace. (Suggest to replace directly, do not make clean. Because after cleaning, you can’t reliably guarantee for the performance of the filter.)

1.2、When you clean Fermentation tank, please use a soft brush to scrub, do not use hard things to scratch, so as not to damage surface of fermentation tank.

1.3、Matched meters should be checked once a year, in order to ensure the normal use.

1.4、Electrical appliances, meters, sensors and other electrical equipments are strictly forbade to directly contact with water and vapor, to prevent them from being affected with damp.

1.5、When stop using the equipments, you should clean them timely and drain residual water in the fermentation tank and the pipeline; Loosening the lid of the fermentation tank and hand hole screw, to prevent seal from producing permanent deformation.

1.6、Carbon steel equipment such as operation platform, constant temperature water tank should be regularly (once a year) brushed paint, to prevent rusting.

1.7、Checking the oil level of reducer timely, if lubricating oil is insufficient, you need to increase timely.

1.8、Replaceing lubricating oil of reducer regularly, to extend its service life.

1.9、If you do not need to use fermentation tank temporarily, you need to empty the fermentation tank and drain residual water in the tank and the pipeline.

2、Announcements

2.1、When you ensure all the single equipments can run normally, you can use this system.

2.2、When you sterilize filters, the steam pressure that flows the air filter should not exceed 0.17 MPa, otherwise filter cartridge will be damaged and lose the ability to filter.

2.3、In the process of fermentation, you should ensure that the pressure in the tank does not exceed 0.17 MPa.

2.4、In the process of real elimination, when through steam to preheat interlayer, you must control inlet steam pressure in the device’s working pressure range (should not exceed 0.2 MPa), otherwise fermentation tank will be damaged.

2.5、When empty and real elimination, you must drain residual water in the jacket of fermentation tank. Otherwise it maybe lead the fermentation tank inside cylinder to be squished, and cause equipments to be damaged; In real elimination, excessive condensation water still can cause the nutrient solution to be diluted, so that it cannot meet the process requirements.

2.6、In the cooling process after empty and real elimination, you must strictly forbid to produce negative pressure in the fermentation tank, so as not to cause pollution, even to damage the equipments.

2.7、In the process of fermentation, pressure in the tank should be maintained between 0.03 to 0.05 MPa, so as not to cause pollution.

2.8、In the process of operation, you must keep the pressure in the air pipeline more than the pressure in the fermentation tank, otherwise it will lead the liquid in the fermentation tank to back into the filter, so that blocking filter core or disabling filter.

2.9、If you meet the problems that you cannot solve by youself, please directly contact after-sales service department of the company. Please do not forcibly remove or repair.
