ZPG vacuum rake dryer (vacuum drying equipment, solvent recovery)
Working Principle
This machine is a novel horizontal intermittent type vacuum drying equipment . The wet material is conductively evaporated. The scraper stirrer continuously removes the material on the hot surface and forms a circulating flow in the container. After the water evaporates, Vacuum pump out.
Performance Characteristics
◎ This machine uses a large area of sandwich heating, heat transfer surface, high thermal efficiency.
◎ The machine is set to stir, so that the material in the cylinder to form a continuous cycle of state, to further improve the uniformity of the material heated.
◎ The machine is set to stir, so that the slurry, paste, paste material can be dried smoothly.
Adaptable Materials
◎ Pharmaceuticals, food, chemical and other industries conduct the following materials drying:
◎ suitable for paste, paste, powder materials;
◎ heat-sensitive materials that require low temperature drying;
◎ easily oxidized, explosive, strong stimulation, highly toxic materials ;
◎ material recovery requires an organic solvent.

Note: The amount of water evaporation is related to the characteristics of the material and the hot air inlet and outlet temperatures. When the outlet temperature is 90 o C, the water evaporation curve is shown in the above figure (for selection reference). As the product is continuously updated, the relevant parameters are changed without prior notice.
