Vacuum harrow dryer used in powder raw materials

ZPD Vacuum harrow dryer used in powder raw materials HVacuum harrow dryer used in powder raw materials harrow dryer used in powder raw materials Dryer

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, pulpinese, paste-like mixture or powder raw materials can be dried easy.

Principle

It is an innovation horizontal batch-type Vacuum harrow dryer used in powder raw materials 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 harrow dryer used in powder raw materials pump.

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 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.
