High drying strength: air flow rate is high in air current dryer, material dispersed well in the gas phase, all the surface of material can be effective as a dry area, therefore, limited drying area greatly increased. Also, because of the dispersion and stir when drying so that the surface gasification constantly updated, so intensity of heating transfer is high.
Short drying time: the contact time between the materials and the air is very short, drying time is usually 0.5 to 5 seconds, for the heat-sensitive and low melting point material it will not cause overheating or decomposition to affect its quality
High thermal efficiency: air current drying adopt the contemporaryoperation of the gas and materials, from beginning to end materials and air temperature can reach a reasonable state,
Drying time is short, so can use a higher drying temperature.
Air dryer is suitable for a wide scope of application, high capacity, large increase of precipitation; simple structure, standing in small size, low investment and maintenance cost.
Hot air Source: oil furnace, gas stove, coal stove, steam heating exchanger.
