Volvo air dryers can be classified according to different characteristics such as operation process, operating high pressure, heating mode, wet material movement mode or structure.

Cool Air dryer can be divided into normal pressure air dryer and the vacuum air dryer, operation can reduce the moisture of the space in the vacuum steam partial pressure and speed up drying process, and can reduce moisture boiling point and material drying temperature, steam is not easy to leak, so the vacuum air drier is suitable for drying heat sensitive, easy oxidation, explosive and toxic materials, and moisture vapor recovery situation;

Air dryers are divided into convection, conduction, radiation, dielectric and other types. Opposite flow air dryer, also known as direct air dryer, is the use of hot dry medium and wet material direct contact, convection transfer heat, and the generated steam away; Conductive air dryer is also known as indirect air dryer. It transfers heat from heat source to wet material through metal partition by conduction mode. The generated wet steam can be removed by vacuum suction, through a small amount of scavenging air or by condensation on the surface of a separate low-temperature condenser. This kind of air dryer does not use drying medium, high thermal efficiency, the product is not polluted, but the drying capacity is limited by the metal wall heat transfer area, the structure is more complex, often operate under vacuum;
