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evaporation, the water is withdrawn from the vacuum pump.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.
