ZB vacuum rake dryer

Working principle

This machine is a novel horizontal intermittent vacuum drying equipment. Wet materials are evaporated through conduction, and a scraper stirrer is equipped to continuously remove the materials on the hot surface and move them inside the container to form a circulating flow. After the water evaporates, it is pumped out by a vacuum pump.

Application scope

Dry materials in industries such as pharmaceuticals, food, and chemicals;
Suitable for slurry, paste like, and powdery materials;
Thermally sensitive materials that require low-temperature drying;
Easily oxidizable, explosive, strongly irritating, and highly toxic materials;

Require the recycling of materials containing organic solvents.

Equipment features

This machine adopts a simultaneous heating method of interlayer and internal stirring, 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.

This machine is equipped with agitation to facilitate the smooth drying of slurry, paste, and paste like materials.
