Working principle

The ZPG series vacuum rake dryer is a novel horizontal intermittent vacuum drying equipment. Wet materials are evaporated through conduction, and a scraper stirrer continuously removes the materials on the hot surface, forming a circulating flow in the container. After the water evaporates, it is extracted by a vacuum pump.

Performance characteristics
This machine adopts a large-area interlayer heating method, with a large heat transfer surface and high thermal efficiency.
The machine is equipped with agitation to create a continuous circulation of materials inside the cylinder, further improving the uniformity of material heating.
The machine is equipped with a mixing system, which enables smooth drying of slurry, paste, and paste like materials.

Adapt to materials
Drying of the following materials is carried out in industries such as pharmaceuticals, food, and chemicals;
Suitable for paste like, paste like, and powdery materials;
◎ Thermally sensitive materials that require low-temperature drying;
◎ Materials that are prone to oxidation, explosion, strong irritation, and high toxicity;
Require the recycling of materials containing organic solvents.

Technical Parameter

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