TECHNICAL FIELD

[0001] The application relates to the technical field of refrigeration cooling devices, in particular to a cooling device for pig blood globulin powder production. BACKGROUND

[0002] The pig blood globulin powder is a powder-shaped protein product prepared through a series of processes such as crushing, extraction, concentration, sterilization and drying of the remaining blood cell part after the fresh pig blood is anticoagulated, separated and the plasma is removed. The pig blood globulin powder needs to be cooled by cold air during production. The existing publication CN1185000 arc-shaped arm scraper wheel 19 discloses a cold air machine for refrigeration, which comprises an air outlet machine body, a water tank, a condensing assembly arranged between the air outlet machine body and the water tank, and a water curtain assembly arranged at two or more different positions on the air outlet machine body and matched with an evaporator to cool hot air. The water curtain assembly arranged at two or more different positions on the air outlet machine body increases the air outlet area of the cold air machine. Two or more water curtain assemblies can work simultaneously or a single water curtain assembly can be used, so that the cold air machine has multiple working modes.
