Semi-auto CIP Cleaning System

1. Operation Procedure and Requirements of Cleaning

1) Operetors are allowed to operate the system only after been trained, which means that operators should be wholly familiar with the structure and performance of CIP equipments.

2) CIP cleaning procedure: water - HNO3 detergent -- NAOH detergent – water: wash for 3 minutes with normal atmospheric temperature water or hot water above 60°C , wash for 10 minutes with density between 1%~2% HNO3 detergent at a temperature between 60°C~80°C wash for 10 minutes with density between 1%~2% NAOH detergent at a temperature 60°C~80°C, if necessary, 20-50PPM Sodium hypochlorite disinfectant should be added properly – wash for 7 minutes with 85°C water in order to sterilizing.

3) Prepare HNO3,NAOH liquid in storage tank according to density requirement out of cleaning processing requirements, and pour 80% of slot capacity of water into the slot.

4) Before operation, operators should carefully check and adjust all the meters on the machines to make sure of stability, accuracy and reliability.

5) According to cleaning processing requirements, operators should accurately set total cleaning time and separate cleaning time of each equipment or pipe, and the temperature controlling range of HNO3,NAOH liquid.

6) Operators should make sure that the detergent inlet and the outlet swinging pipe on the equipment to be washed are correctly connected on detergent outlet pipe layout, and then start the centrifugal pump to start cleaning.

7) NAOH liquid can not be used for over 3 times, it should be updated timely according to dilution and pollution condition.
