What is the truck's air dryer and what does it do

The air dryer is through the heating of the material moisture (generally refers to moisture or other volatile liquid components) vaporization escape, in order to obtain the specified moisture content of solid materials equipment

Heat transfer from high-temperature heat source to wet material in various ways, so that the material surface moisture vaporization and escape to the outer space, thus the material surface and internal moisture content of the difference. The internal moisture diffuses to the surface and vaporizes, which makes the wet content of the material decrease continuously and gradually completes the drying of the material as a whole
