1. Vacuum Rake Type Dryer is used for pharmaceutical and foodstuff. as the following raw material.
2. suitable for pulpiness, paste-like mixture or powder raw materials which is with low temperature.
3. raw material is easy to oxidize or explode and have strong irritative or toxic.
4. raw material that need to recover solvent.

Working Principle

Rake vacuum dryer unit is usually a batch vacuum one, which is mainly composed of vacuum paddle dryer, heat sources, vacuum unit and filter. Rake vacuum dryer consists of shell, end plate, agitating shaft, driving unit, rotary joint, supporting part and control systems etc. Wet materials are indirectly heated by the heating-medium (steam heat-conducing oil, etc) via jacket and hollow shaft. The moisture is vented by a vacuum pump. Condenser can be added if solvent needs recovered. It is an innovation horizontal batch-type vacuum dryer.The moister of wet material will be evaporated by heat transmission. The stirrer with squeegee will remove material on hot surface and move in the container to form cycle flow .The evaporated moisture will be pumped by vacuum pump.

Characteristics

◎Being adapted the big area heating way , its area is large and its heat ef ciency is high.
◎Being installed stirring in the machine, it makes raw material in cylinder form the state of continuous circle inside the cylinder , so the uniformity to be heated of raw material is raised greatly .
◎Being installed stirring in the machine, pulpinese, paste-like mixture or powder raw materials can be dried easy .

Material to be dried

◎The following raw materials from pharmaceutical industry , foodstuf findustry, chemical industry and so on can be dried.
Suitable for pulpiness, paste-like mixture or powder raw material.
◎Thermal sensitive raw material having the requirement to dry at lower temperature.
◎Raw materials that are easy to oxidize or explode and have strong irritative or toxic.
◎Raw materials that need to recover solvent.
