Product Description

Vacuum Rake Harrow Dryer


      Horizontal batch-type vacuum drier improved on the basis of absorbing technology of domestic rake drier. The moisture of wet material will be evaporated by heat transmission. The stirrer with grinding scraper will remove material on hot surface and move in the container to form cycle flow. The evaporated moisture will be drawn out by vacuum pump.


     1. Being adapted large-scale jacket heating, its heat conducting area is large and heat efficiency is high.

     2. Being installed stirrer in the machine, it makes raw material form the state of continuous circle inside the body, so heating uniformity of raw material is raised greatly.

     3. Being installed stirrer in the machine, slurry and paste shape material can be dried easily.

     4. Special design for discharging port, make better sealing and less material accumulation, discharge is easy. (The design had been apply patent)

     5. There are two seal model, mechanical seal and packing seal. The design supply good seal and long life.

     6. The special techniques of shaft and rake support high strength and concentric.

     7. The medium in shaft and vibration adding equipment will be equipped by requirement

     8. Use different filter form according to different material.

     9. Being adapted half-pipe type jacket when the volume of vacuum rake drier 5 m³.


The following raw materials from pharmaceutical industry, foodstuff industry, chemical industry and so on can be dried. Suitable for pulpiness, paste-like mixture or powder raw materials. Thermal sensitive raw materials having the requirement to dry at lower temperature. Raw materials that are easy to oxidize or explode and have strong irritative or toxic. Raw materials that need to recover solvent.
