The biconical vacuum dryer material is dried by principle or vacuum application. When water boils at lower temperatures, the pressure is reduced by creating a vacuum. So the evaporation of water occurs faster. The structure of the vacuum drying equipment is a high vacuum pressure from a steam pressure bracket with a cast iron re-sleeve container and a jacket. It has enclosed space and is divided into 20 hollow shelf sections, part of their sheath. These shelves are placed on the shelves due to the large surface area provided by the shelves and metal trays of about 45 to 50 square meters to maintain the heat transfer provided by the material. The oven door is locked tightly to obtain a hermetic seal and is connected to a vacuum pump by connecting the condenser.
Double cone vacuum dryer processing:
This is currently the tray in the dryer that is used to dry the material placed on the shelf and the pressure is reduced to 30-60 KPS through the vacuum pump. The door closes tightly and the steam passes through the space of the jacket and the bookshelf. Thereby heat transfer occurs through the mechanism of conduction. The water subjected to vacuum evaporation is taken from the material at 25 - 30 @c. The water vapor is passed through the condenser and the dry vacuum line and then the material is collected from the tray.
Double cone vacuum drying mechanism drug application:
The vacuum drying equipment can be used for the following drying heat sensitive materials, dusty materials, hygroscopic materials, and toxic substances can be dried in this vacuum dyeing machine. The material containing the solvent is also dried by this vacuum drying equipment. The solvent material can be recovered by the condensation process. This is a necessary drug for porous end products. A fragile dry extract can be obtained by this drying process.
advantage
1. The treated material is easy to dry in the tray due to the internal tray of the dryer.
2. It is easy to switch to the next material.
3. Empty shelves They can be used for electric heating.
4. It provides a large surface area. So heat can be easily transferred across the entire machine and the drying fast acting body.
5. Hot water can be supplied throughout the dryer at the desired temperature to aid in the drying process.
Disadvantage
1. The dryer is a batch process.
2. It is inefficient.
3. This is more expensive.
4. The operation of the dryer with excessive labor costs.
5. There is also overheating due to the danger of steam.
