This equipment consists of drying - - water catching system, vacuum system, refrigerating system, medium system, material conveying system and computer control system, etc..

Two freezing methods: Fluidized monomer quick-freezing

Ram slow-freezing during freezing

Three material feeding ways: Freezing and drying during mild material freezing
