[0060] 4. CIP procedure: The CIP procedure is divided into liquid preparation procedure and cleaning procedure.

[0061] ① Liquid Preparation: Before CIP cleaning, you must prepare the acid, alkali, or water needed for cleaning. Enter the liquid preparation parameters in advance and click "Select the desired liquid type and start." The system will automatically prepare the liquid. When the set concentration and temperature are reached, the system will determine that the liquid preparation is complete and automatically end the process.

[0062] ②Cleaning procedure: Before performing CIP cleaning, you must first ensure that the material in the cleaning target has been emptied and the conversion board of the cleaning pipeline has been correctly connected. Set the "cleaning target" and "cleaning recipe". The parameters have been set according to the on-site conditions. Do not change them at will unless necessary. When the target is correctly selected, the system will automatically read the cleaning parameters of the corresponding target. After clicking the "Start" button, the system will automatically clean the target. After the cleaning is completed, the system will automatically stop. After the cleaning is completed, the system will detect the conductivity and temperature of the cleaning liquid 504 returning to the cleaning station. If both meet the set requirements, the system will operate normally. If the temperature is not enough, the system will temporarily stop the timer and start the heater to heat the circulating cleaning liquid 504. If the conductivity is not enough, the system will temporarily stop the timer.
