Introduction：1. The boiling point of the material solution decreases under vacuum, which increases the heat transfer driving force of the evaporator, thus saving the heat transfer area of the evaporator for a certain amount of heat transfer. 2. The heat source for evaporation operation can be low-pressure steam or waste heat steam. 3. The evaporator has less heat loss and can achieve a higher drying rate at lower temperatures, fully utilizing heat. 4. Can dry unstable or heat sensitive materials at low temperatures, as well as materials containing solvents and requiring solvent recovery. 5. Disinfection tr···
