PLC Module Vacuum Harrow Industrial Dryer Machine For Food Materials

Vacuum Harrow Dryer Continuous Drying Equipment For Food And Chemical Viscous Materials
  Products descriptions  
       ZPG vacuum rake dryer is a novel horizontal intermittent vacuum drying equipment. The wet material is evaporated by conduction, and the scraper agitator continuously removes the material on the hot surface, and moves in the container to form a circulating flow, and the water evaporates. It is then pumped out by a vacuum pump. The machine adopts a large-area interlayer heating method, which has a large heat transfer surface and high thermal efficiency. The stirring is set to make the material form a continuous circulation state in the cylinder, which further improves the uniformity of the heating of the material, so that the drying can be carried out smoothly.

 
  Products Principle   
       In the vacuum condition, boiling point of the solvent is decreased,and air is isolated, it avoids the material from being oxidized and deterioration. Input heating medium (hot water, hot oil) into the jacket, and feed damp material into the drying chamber.Harrow-teethed shaft stirs the material to make the heating progress uniform. When achieving the drying requirements, open the discharging valve at the bottom of the chamber, under the stirring action of the harrow teeth, material moves to the middle and discharged.
The moisture of wet material will be evaporated by heat transmission. The stirrer with squeegee will remove material on hot surface and move in the container to form cycle flow. The evaporated moisture will be pumped by vacuum pump.

 
  Products 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;

 
  products parameters   

Note: The evaporated amount of water its related to the characteristics of raw materials and the drying temperature. With renew products unceasingly, the related parameter will be exchanged, it does not announce in advance.
