Working Principle

Vacuum harrow dryer is a novel horizontal intermittent vacuum drying equipment, wet material evaporation by conduction, with a scraper stirrer to continuously remove the material on the hot surface, and in the container pushed to form a circulating flow, water evaporation by the vacuum pump pumped away.

Equipment features

This machine adopts large-area sandwich heating method, with large heat transfer surface and high thermal efficiency.
The machine is set with stirring, so that the material forms a continuous circulation state in the cylinder, which further improves the uniformity of the material's heating.
The machine is set with stirring, so that it can smoothly carry out the drying of prize, paste and pasty materials.

Scope of application

※ Suitable for slurry, paste and powder materials.
※ Heat-sensitive materials requiring low-temperature drying.
※ Easy to oxidise, easy to explode, strong irritation, highly toxic materials.
※ Materials requiring recovery of organic solvents.
