Integrated CIP cleaning unit operation and use

Integrated CIP cleaning unit operation and use

1. The operator must be fully familiar with the structure and performance of the equipment, and can be put into operation after training.

2. The equipment must be carefully inspected for internal cleaning of tanks and pipes before and after use.

3. In the storage tank, prepare the acid and alkali solution according to the concentration specified in the cleaning process, and inject clear water into the clean water tank. The loading factor of the volume storage liquid is 80%.

4. Carefully check and adjust the instruments of the equipment to make their work stable, accurate and reliable.

5. According to the cleaning process requirements, determine the total time and time of each cleaning of each equipment or pipeline and the temperature control range of the acid and alkali solution.

6. Connect the swinging tube of the cleaning liquid inlet and the outlet of the equipment to be cleaned on the distributor of the cleaning liquid output line. After checking and confirming that the pipe connection is correct, the centrifugal pump can be started for cleaning. When the equipment is being cleaned. The opening and closing of each valve are manual operation.

7. CIP cleaning procedure: clear water → lye → clear water → acid → clear water. The time of the whole cleaning process and procedure can be determined by each manufacturer according to actual needs. For some equipment or pipelines that are relatively easy to clean, it is not necessary to pickle, that is, clean by water: lye → water. For example, if the entire cleaning process of a device is 35 minutes, it can be determined as follows:

*Second water cleaning time: 5 minutes

Lye cleaning time: 10 minutes

Second clean water cleaning time: 3 minutes

Acid cleaning time: 10 minutes

The third clean water cleaning time: 7 minutes
