Why is it necessary to perform CIP cleaning on beer equipment?

The CIP (Clean-In-Place) system mainly consists of recovery tanks, alkaline tanks, acid storage tanks, sanitizer tanks, and sterile water tanks, each carrying specific cleaning and sterilization tasks. The recovery tank collects sterile water from the final rinse for storage and pre-washing of other systems. The alkaline tank stores alkali solutions or alkaline detergents prepared according to process requirements, typically equipped with external heaters for forced circulation heating to achieve rapid heat exchange. During thermal cleaning processes, steam is introduced through the external heater to heat the alkali solution to a predetermined temperature. The purpose of alkaline washing is to remove organic residues generated within the system. The acid storage tank stores acidic detergents used to remove inorganic residues such as calcium and magnesium salts. The sanitizer tank stores sterilizing agents at specified concentrations, while the sterile water tank provides treated sterile water for rinsing and elevating the overall sterility level of the system.

In daily use of beer equipment, tanks and pipelines inevitably accumulate bacteria and dirt. To ensure the purity and flavor of beer, the CIP cleaning system plays a crucial role. Initially, residual solids and liquids inside the equipment are flushed out with a large volume of water, laying the foundation for subsequent detergent cleaning. Alkaline or acidic detergents are then used for deep cleaning to thoroughly remove residues. In the rinsing phase, sterile water is used to wash away any remaining detergent until the water quality is neutral. Finally, appropriate disinfectants are used for a final rinse to ensure the internal sterility of the equipment.
To ensure the CIP (Clean-In-Place) system operates effectively, regular inspections and maintenance procedures are essential. This includes verifying cleaning agents and sanitizers weekly, with daily checks in cases where concentrations fluctuate significantly during operations. Sampling and inspecting CIP operations involve evaluating solid content and color in cleaning agents to assess contamination levels. Under normal operation, cleaning agents in CIP tanks should be discharged every 6 to 8 weeks. Implementing a regular calibration schedule ensures the measurement components of the CIP system operate reliably. Equipment should undergo annual inspections and maintenance to remove scale deposits from tanks, assess corrosion levels, and ensure the system operates safely.
