[0034] The waste liquid recycling and treatment unit 4 includes a waste liquid collection tank 41, which is located at the lowest point of the egg white liquid production device to facilitate the rapid collection of cleaning waste liquid discharged from the cleaning drain pipe 215. A filter grid 42 is installed at the bottom of the waste liquid collection tank 41 to initially intercept large particulate impurities. The waste liquid collection tank 41 is connected to a multi-stage purification device 44 through a waste liquid pump 43. The multi-stage purification device 44 removes contaminants such as proteins, oils, and minerals from the cleaning waste liquid. At the same time, the purified cleaning liquid is returned to the purification liquid storage tank 45 through a return pump. The purification liquid in the purification liquid storage tank 45 enters the cleaning main pipe 15 through the purification liquid pump 46 and the purification liquid solenoid valve 47 to replace the pre-rinse water for pre-rinse operations. Practical application verification shows that the recycling rate of the purification liquid can reach 60%-70%, which significantly reduces the consumption of cleaning agents and wastewater discharge.

[0037] During use, the CIP cleaning system units should be rationally arranged according to the layout of the egg white production workshop to ensure tight pipe connections and no leaks, and that electrical wiring is standardized to avoid interference. Then, each sensor should be calibrated to ensure accurate measurement data. The pumps, valves and other actuators should be tested for linkage to check the coordination of actions. The operator sets the cleaning parameters through the touch screen 33.

[0038] After production, a pre-rinse is performed. The PLC controller 32 starts the pre-rinse program and controls the pre-rinse solenoid valve 144 or the purification liquid solenoid valve 47 to perform the pre-rinse operation, initially removing loose egg white and impurities from the equipment surface. The waste liquid enters the waste liquid recycling and treatment unit 4 through the cleaning drain pipe 215. After the pre-rinse is completed, an alkaline washing operation is performed. The PLC controller 32 automatically switches to the alkaline washing process. The alkaline cleaning agent is heated to 60-70℃ through the alkaline washing heat exchanger 125 and then begins the cleaning operation to remove the attached protein dirt. After the alkaline washing is completed, an intermediate rinse is performed to remove residual alkaline cleaning agent. After rinsing, acid washing is performed to remove possible scale and stubborn stains. After acid washing is completed, a final rinse is performed using hot water at 80-90℃ at a flow rate of 1.0-1.5m³ / h for 15-20 minutes until the drainage is clear and odorless, ensuring that there is no residual acid or dirt on the equipment.

[0039] After cleaning, hot air or negative pressure suction can be used to quickly dry the inside of the equipment, preventing water residue from breeding microorganisms and preparing it for the next production.
