Vacuum Rake Dryer Product Features: This machine adopts a large-area jacketed heating method, resulting in a large heat transfer surface and high thermal efficiency.
The machine is equipped with a stirrer, creating a continuous circulation of material within the drum, further improving the uniformity of heating.
The stirrer allows for the smooth drying of slurry, paste, and paste-like materials.
Working Principle: This machine is a novel horizontal intermittent vacuum drying device improved based on technology introduced from the Shanghai Chemical Equipment Research Institute. Wet material undergoes conduction evaporation, with a scraper stirrer continuously removing material from the heated surface and pushing it within the container to form a circulating flow. After the moisture evaporates, it is extracted by a vacuum pump.
Applications of Vacuum Rake Dryer: Suitable for drying the following materials in the pharmaceutical, food, and chemical industries:
1. Suitable for slurry, paste, and powder materials;
2. Heat-sensitive materials requiring low-temperature drying;
3. Easily oxidized, explosive, highly irritating, and highly toxic materials;
4. Materials requiring organic solvent recovery.
