The refrigeration tank consists of a tank body and a compressor. The tank wall uses advanced honeycomb panels for direct heat exchange and refrigeration with the milk. The refrigeration compressor uses a fully enclosed Copeland compressor unit from the USA, along with imported expansion valves and solenoid valves equipped with a reliable midpoint protector to prevent compressor burnout due to overload or system failure. The tank body is made of SUS304 stainless steel and features a pressurized automatic rotating cleaning CIP spray head and an automatic stirring device. The insulation layer uses polyurethane foam, providing excellent thermal insulation performance.
