The drying equipment uses a vacuum system to evacuate the material while heating the material

The working process of the double-cone vacuum dryer is a drying equipment integrating mixing and vacuum drying. The working process of the double-cone vacuum dryer is to place the material to be processed in a sealed cylinder, and use the vacuum system to evacuate the material while heating the material, so that the internal moisture passes through the pressure. The difference or concentration difference diffuses to the surface.

When vacuuming and heating, the drying speed is slow. When the material is heated to above the vaporization temperature of water, the drying speed will be significantly accelerated. The material is heated to the vaporization temperature under the corresponding pressure within the allowable temperature range and vaporized in large quantities. At this time , The heat of the material to be processed remains unchanged, and the added heat is converted by other methods. The vacuum system continuously discharges the vaporized steam to maintain the pressure difference between the evaporation surface and the space, so that the drying continues.

Main disadvantages of drying equipment rotary vacuum dryer

The main disadvantage of the rotary vacuum dryer is that it needs a vacuum system that can pump water vapor, which makes the equipment investment and operation cost high; the equipment production efficiency is low and the output is small. However, with the continuous development of technology, the performance and efficiency of rotary vacuum dryers have been greatly improved.

The rotary vacuum dryer is a new type of dryer that integrates mixing and drying. The condenser, vacuum pump and dryer are matched to form a vacuum drying device. When the material is dried in the rotary vacuum dryer, it is constantly turned over, and the drying is more uniform and abundant. The boiling point of the material solvent is lowered under vacuum, so it is suitable for drying unstable or heat-sensitive materials.
