Working principle
This machine is a new type of horizontal intermittent 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, it is pumped out by a vacuum pump.
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 paste, paste, paste material can be dried smoothly.
Adapt to the material
◎ The following materials are dried in the pharmaceutical, food, chemical, and other industries:
◎ Suitable for paste, paste, powder materials;
◎Requires low-temperature dry heat-sensitive materials;
◎ Easily oxidized, explosive, strong irritant, highly toxic materials;
◎Requiring the recovery of organic solvent materials.

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 90oC, the evaporation curve of its moisture is shown in the above figure (for selection reference). As the product is continuously updated, the relevant parameters are changed without prior notice.
