Horizontal Vacuum Drying Equipment , Rotary Rake Vacuum Belt Dryer Stable Performance
The vacuum kneading dryer has the characteristics of low drying temperature, large drying rate, energy saving, good equipment tightness and easy recovery of solvent. It is especially suitable for materials that are not resistant to high temperature, easy to oxidize at high temperature or easy to produce powder when dry (such as Kinds of dyes, as well as the need to recycle solvents or materials containing toxic gases and other drying operations, and have the advantages of quality and does not damage the inherent properties of materials, widely used in petrochemical, food and pharmaceutical, dyes and other industries.
Foreign research on vacuum kneading dryers is relatively early, especially in recent years, most of them are research and development from the aspects of increasing heat transfer area and improving heat transfer efficiency. A vacuum kneading dryer for continuously drying paste materials has been produced in China.
Description: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.

◎Being adapted the big area heating way , its heat conducting 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.
