High Output Harrow Vacuum Paddle Rotary Drum Dryer For Drying The Paste Materials/Flash Dryer/Drum Dryer
Introduction
A rotary vacuum dryer is a horizontal cylindrical jacketed shell with a hollow agitator, rotating in close clearance. In a batch operation, drying is done under a vacuum, heating is done through the jacket. The dryer offers a simple but effective method of drying wet cakes and sometimes slurries.
WORKING PRINCIPLE
Vacuum Harrow Dryer is an innovative horizontal batch-type vacuum dryer improved on the basis of the introduced technology of the rotary vacuum harrow dryer.
The moister of wet material will be evaporated by heat transmission. The stirrer with the blade will remove material on a hot surface and move in the container to form a cycle flow. The evaporated moisture will be pumped by the vacuum pump.
Features
1. Being adapted the big area heating way, its heat conducting area is large and its heat efficiency is high.
2.Being installed stirrer in the machine, it makes raw material in cylinder form the state of continuous circle inside the cylinder, so the uniformity for raw material’s being heated is raised greatly.
3. Evaporation intensity is high,in general it can evaporate10~15 kg (water)/m2.h.
4.The powder in solvent vapor is filtered by the bag filter, there is no environmental and product recovery ratio is high.
5. Being installed stirring device in the machine, pulpiness, paste-like mixture or powder raw materials can be dried easily.
Widely applicable for quick drying. Because the harrow Vacuum Dryer has jacket that the heating medium will flow into jacket so the dryer has enough drying area.
7. To increase the drying efficiency, Xiandao design the special crushing device. During drying process, the crushing device will break the caking material to powder; Combined with the magnetic filtration technology, the output product will more purity.
8. Under the vacuum state, the boiling point of the water and solvent is reduced. Therefore it is suitable for most of materials with different properties and states. Particularly it is suitable for material that is easy to explode and oxidize.
9. Low energy consumption .With patented design, Xiandao can ensure that the temperature of the outside surface of the dryer is 25-35℃; it will reduce the heating dissipation;
10. The quality of product is good. Because of periodic clockwise and counterclockwise rotation the material will be uniformly drying.
11. As optional, the dryer can be combined with cloth bag filter, solvent recovery unit, product cooling unit ;
12. Advanced mechanical sealing device adopted. Xiandao ensures the vacuum degree and heating medium without leakage.
13. With PLC module, client can save the processing program.
14. Combined with the magnetic filtration technology, the output product will achieve higher purity.
15. The electronic systems and their safety should comply with the requirements set forth in 21 CFR Part 11 and GMP Annex 11; the data should be collected at appropriate time intervals and stored in the system in a fixed format that can be printed out/read;
