ZHG rotary vacuum paddle dryer is especialled designed for drying sticky paste and heat sensitive material. - details see: https://www.machineto.com/zhg-rotary-vacuum-paddle-dryer-10297022

Principle

This rotary vacuum dryer give drying, mixing and breaking effects simultaneously. Wet cake or slurry is fed through charging door, while the agitator is rotating in clockwise direction, vacuum is applied in the dryer and heating media is circulated in the jacket. Evaporation of moisture takes place under vacuum and vapors passes through the dust catcher into the condenser, where it is condensed and collected in the receiver. Dried material is discharged through discharge valve. The lump breaker rods are provided to achieve good drying effect.

This is a high efficiency dryer unit used for drying of wet cake product after filtration. This equipment can be used in drying process of various Pharmaceuticals, Intermediate Compounds, Fine Chemicals, Chemicals, Agro Chemicals, Pesticides, Insecticides, Dyes and Food Products.

Features

1) The special designed jacket can make sure high heat efficiency and stable heat transfer.

2) The paddles and screw ribbon are penetrate-welded on to the shaft which is flexible and corrosion resistant. The stable rotation of rakes and twin screw ribbon can well stir up and completely mix up the wet material to dry it uniformly.

3) The finish machined bearing seat, tapered roller bearing and spherical roller bearing can perfectly guarantee the concentricity, mechanical seal and lifespan.

4) The rotating shaft is also filled with heat medium to increase the heat transfer area.

5) The filter bag can well separate the dust from the chamber to protect the whole vacuum system.

6) Special designed discharging valve can make sure the movable plate is flush with inner chamber wall to completely avoid the wet material accumulates in the valve without drying.

7) The control cabinet is isolated installed with all the buttons interlocked. All the electrical components are famous brand.
