The double cone vacuum dryer material is dried by application of principle or vacuum. When the water boils at a lower temperature, the pressure is reduced by creating a vacuum. So the evaporation of water happens faster. The structure of the vacuum drying apparatus is a high vacuum pressure from a cast iron heavy-jacketed container and a steam pressure stand erected in the jacket. It has a closed space and is divided into 20 hollow shelf parts that are part of their sheath. These shelves are placed on the shelves due to the large surface area provided by the shelves and metal trays, approximately 45 to 50 meters square, to maintain the heat conduction provided by the material. The oven door is locked tightly and hermetically sealed, and by connecting the condenser to a vacuum pump.
Double cone vacuum dryer processing:
This is currently the tray in the dryer is used to dry the material which is placed on the shelf and the pressure is reduced to 30-60 KPS through the vacuum pump. The door is closed tightly and steam passes through the space of the jacket and the bookshelf. As a result, heat transfer occurs through the mechanism of conduction. Water evaporated in vacuum was removed from the material at 25 - 30 @c. The condenser was disconnected from the dry vacuum line and then the water vapor was collected after the material was collected from the tray.
Double Cone Vacuum Drying Machine Application:
Vacuum drying equipment can be used for the following dry heat-sensitive materials, dusty materials, hygroscopic materials, toxic substances can be dried in this vacuum dyeing machine. The solvent-containing subscription material is also dried by this vacuum drying device. Solvent materials can be recovered during the condensation process. This is a drug required for porous end products. The fragile dry extract can be obtained by this drying process.
advantage
1. The processed material is easy to dry in the dryer due to the internal tray arrangement.
2. It is easy to switch to the next material.
3. Empty shelves They are electric heating can be used.
4. It provides a large surface area. So the heat can easily transfer in the whole machine and the fast-moving main body.
5. Hot water can be supplied throughout the dryer at the desired temperature to aid in the drying process.
Shortcomings
1. The dryer is an intermittent process.
2. It has low efficiency.
3. This is more expensive.
4. The labor cost of the dryer is too high.
5. There is overheating due to the danger of steam.
