Sweet Potato Double Drum Dryer Food Processing 20kw Continuous Rotation

Potato , Sweet Potato Drum Scraper Dryer , Low Energy Consumption , Environmental Protection, Easy To Operate

  Principle  

Drum dryer is a kind of continuous drying equipment through steam jacket-ed heating. The rotating cylinder body is attached to a certain thickness of the liquid raw material film through the material tank set in the lower part. The sensible heat (Steam) is passed through the tubes to the inner and outer wall of the drum bodies, and then is conducted to the liquid raw material film, so that the moisture content of the raw material is rapidly evaporated and the paste reaction occurs. With the continuous rotation of the drum bodies, finally material is completely dried and the pasting process accomplishes.

The completely dried products are scraped off the rotating cylinder body by the scrapers installed in the surfaces of drums body, and then gathered in the screw conveyor at the bottom of the scrapers. At the discharge end of screw conveyor, a crushing device is set. After being crushed and flake products is to

conveyed to the clean room for weighing and packing. At this point, the drying and pasting process accomplishes.

  Features  
      ---high heat efficiency. Because the heat transfer mechanism of rolling scraper dryer belongs to heat conduction, the heat transfer direction is consistent throughout the operation cycle, except for cover heat dissipation and heat radiation loss, the rest of the heat is all used for the evaporation of simple material film wet division, the thermal efficiency can reach 70%-80%.

      ---operation flexibility. Wide applicability. Many drying factors of drum scraper dryer can be adjusted. For example, the concentration of the feed, the thickness of the coating material film, the temperature of the heating medium, the rotation speed of the drum, etc., can change the drying efficiency of the roller scraper dryer, and many factors are not related to each other. This brings great convenience to the drying operation of the roller scraper, so that it can adapt to the drying of a variety of materials and different output requirements.

      ---Short drying time. Drying cycle of materials - generally only 10-300 seconds, suitable for heat sensitive materials. If the roller dryer is set in a vacuum, it can be operated under reduced pressure.

      ---the drying rate is large. Since the material film smeared on the cylinder wall is very thin, generally 0.3-1.5mm, and the heat and mass transfer directions are consistent, the evaporation intensity of the material film surface can be maintained at 20-70kgH₂O/m²h.
