Double Cone Vacuum Dryer

  • It has a higher speed at a lower temperature, which is 2 times faster than the general drying equipment, saves energy, and has a high heat utilization rate. It is especially suitable for drying heat-sensitive materials and oxidizable materials.
  • The internal structure is simple, the cleaning is easy, the material can be completely discharged, and the operation is simple.
  • It is closed and dry, and the product has no leakage and no pollution. It is suitable for the drying of strong irritating and toxic materials.
  • The materials are mixed and dried during rotation, and the materials can be dried to a very low water content (≤0.5%), and the uniformity is good, which is suitable for different material requirements.
  • The equipment is compact in structure, small in floor space, easy to operate, reduces labor intensity and saves labor.

Working Principle

The main machine of the double-cone rotary vacuum dryer is a double-cone tank. Under the vacuum state in the tank, steam or hot water is introduced to heat the inner tank, and the heat is transferred to the wet material through the inner tank to vaporize the moisture in the wet material.

The motor drives the tank body to rotate, the material is constantly turned up and down, inside and out, and the heating surface is replaced. At the same time, the water vapor is continuously pumped away through the exhaust pipe through the vacuum pump, which speeds up the drying rate of the material and finally achieves the purpose of uniform drying..

Applicable Materials

  • Heat-sensitive materials that cannot withstand high temperatures;
  • Materials that are easily oxidized and dangerous;
  • Materials that do not allow damage to crystals;
  • Materials that need to recover the steam discharged during drying;
  • Materials that need to recover solvents and toxic gases;
  • Materials with extremely low residual volatile content are required.
