PZG Series Vacuum Harrow Drying Machinery

Principle
It is an innovation horizontal batch-type vacuum dryer. The moisture of raw 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 discharged by vacuum pump.

Features
Being adapted the big area heating way, its heat conducting area is large and its heat efficiency 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, pulpiness, paste-like mixture or powder raw materials can be dried easily.

Applications
The following raw materials from pharmaceutical industry, foodstuff industry, chemical industry and so on can be dried.
Suitable for pulpiness, paste-like mixture or powder raw materials.
Thermal sensitive raw materials 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.
