The equipment consists of a milk tank, hot water tank, cold water tank, circulating pump, compressor, and base. It features a stirring mechanism, an automatic temperature control system, and an adjustable sterilization temperature of 40-90°C. The compressor circulates and cools the water to approximately 10°C. Sizes from 100L to 200L can be customized. An added cold water circulation system allows for preheating/precooling of the water tank. Continuous use results in greater energy savings.
