ZPG vacuum rake dryer

working principle

This machine is a novel horizontal batch vacuum drying equipment. The wet material is evaporated by conduction, and the scraper stirrer continuously removes the material on the hot surface, and moves in the container to form a circulating flow. After the water evaporates, it is pumped out by the vacuum pump. 

Performance characteristics
◎This machine adopts large-area interlayer heating method, with large heat transfer surface and high thermal efficiency.
◎This machine is equipped with stirring to make the material form a continuous circulation state in the cylinder, which further improves the uniformity of the heating of the material.
◎This machine is equipped with stirring, so that it can smoothly dry slurry, paste and paste materials.

Adapt to materials

◎Dry the following materials in medicine, food, chemical and other industries:
◎Suitable for paste, paste and powder materials;
◎ Heat sensitive materials requiring low temperature drying;
◎Easily oxidized, explosive, strongly irritating, highly toxic materials;
◎Materials requiring recovery of organic solvents.

Technical specifications

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