Vacuum Drier Create A Vacuum Reduction
- May 15, 2017 -

In double-cone vacuum dryer material Vacuum Drier is dried by the application of the principle or vacuum. When the water boils at a lower temperature, the pressure is reduced by creating a vacuum. So the evaporation of water takes place faster. The structure of the vacuum drying Vacuum Drier equipment is high vacuum pressure by the steam pressure bracket with the cast iron heavy jacket container. It has been enclosed in space and is divided into 20 hollow shelf sections of their sheath. These shelves, due to the larger Vacuum Drier surface area by the shelf and metal plates, are provided about 45 to 50 meters square on the shelf, used to maintain the heat conduction provided by the material. The oven door is locked tightly sealed, and the condenser is connected to a vacuum pump.

Double cone Vacuum dryer machining:

This is currently in the dryer tray Vacuum Drier is used to dry the material placed on the shelf and the pressure decreases to 30-60 KPS through the vacuum pump. The door closes tightly and the steam passes through the jacket and the shelf space. Thus the heat transfer occurs through the mechanism of conduction. The vacuum evaporation of the water is removed from the material in 25-30 @c. After the condenser Vacuum Drier and the drying vacuum line disconnect then the material is collected from the tray after the water vapor passes.

The application of double cone vacuum drying mechanism:

Vacuum drying equipment can be used in the Vacuum Drier following drying heat-sensitive materials, dust materials, hygroscopic materials, toxic substances can be in this vacuum dyeing machine drying. It is a solvent-containing subscription material that is also dried through this vacuum dryer. Solvent materials can be recycled during condensation. This is essential for the porous terminal product Vacuum Drier of the drug. The fragile dry extract can be obtained through this drying process.


1. The processing of the material is easy in the drying due to the interior tray layout of the dryer.

2. It is easy to switch to the next Vacuum Drier material.

3. Empty shelves They are electrically heated to use.

4. It provides a large surface area. Therefore the heat can be transferred easily in the whole machine and the body of the drying fast motion occurs.

5. Hot water can be used throughout the dryer for its desired temperature to help in the drying process.


1. The dryer is an intermittent process.

2. It is inefficient.

3. This is more expensive.

4. The operation of the dryer with high labor costs.

5. There is also overheating, due to the danger of steam.
