This CIP cleaning system is mainly used for cleaning pipelines, tanks, and filling machinery that come into direct contact with materials. It can be manually selected to connect with equipment such as bottle washing machines, sealing machines, filling machines, etc. to form an automatic cleaning device. High temperature and high concentration cleaning solution is used to exert strong force on the equipment, so that different areas of the equipment are sprayed with water at different temperatures. The surfaces in contact with food can be cleaned without disassembling or moving the device, achieving a certain cleaning effect, improving product safety, better ensuring operational safety, and saving energy such as water and steam, which can reduce the amount of detergent used. It is the ideal preferred cleaning equipment for beverage manufacturers.
