Air drying device is a continuous pressure of the dryer. Wet granular or powdered material through the belt feeder enters from the bottom of the dryer air dryer principle, but also into the homemade hot drying medium from the bottom of the dryer air dryer, and reach a certain velocity dispersion of the wet material and suspended in gas flow and heat medium in the material flow along together while drying tube upward mobility characteristics air dryer, heat and mass transfer occurs efficiently, achieve rapid drying purposes. Proper installation of the fan location in the system, the air dryer can operate under positive pressure, for toxic or potentially large dust pollution, the use of vacuum operation, the product should not be leaked, is conducive to maintaining the production environment; and also help reduce moisture vaporization temperature, protect heat-sensitive materials. But this time the fan is in working state pumping, the pumping of the gas temperature is higher, and may contain some of the particles and dust, and therefore the fan higher, while energy consumption increases. Material in the presence of moisture in the air dryer temperature state to speed the flow of hot air in the drying tube, the residence time is very limited, therefore, generally apply only to material non-binding constant drying process water surface evaporation. Practice shows that under these conditions the presence of moisture, granular materials can be dried in a drying gas flow tube and, ultimately, a water content of 0.3% to 0.5% of the product. For as the diffusion of moisture migration within the material wet material is completely inappropriate for air drying process.
