ZPG Series Vacuum Harrow/Rake Dryer For Thermal Sensitive Raw Material At Low Temperature
Introduction
ZPG vacuum rake dryer uses large areas of layers to do heat, thus enable large heat transfer area and high thermal efficiency. Stirring is set so that the materials in the barrel form a state of continuous circulation, further improving the uniformity of the material being heated, allowing smooth drying of pasty, creamy and mushy materials.
Working Principle
ZPG vacuum rake dryer is a new kind of horizontal batch vacuum drying equipment. The wet materials experience conduction and evaporation. Blade stirrer continuously removes materials from hot surface, and develops a recycle stream in the container. After evaporation, the water is withdrawn from the vacuum pump.
Features
1. This dryer adapted the interlayer heating technology. The heat conducting area is large and the heat efficiency is high.
2. This dryer is equipped with stirring device; it keeps the raw material in a continuous circling status inside of the cylinder
so the heating uniformity is improved greatly.
3. With the stirring functions, the dryer can easily dry the pulpiness, paste-like mixture or powder materials.
Application
In industries of medicine, food and chemical, it is used to dry following materials.
Applied in pasty and powdery materials.
Heat-sensitive materials requiring low-temperature drying.
Easily oxidized, explosive, strong-irritant and highly-toxic materials.
