空气干燥机是通过加热使物料中的湿分(一般指水分或其他可挥发性液体成分)汽化逸出，以获得规定湿含量的固体物料的机械设备。
Air dryer is a mechanical equipment that vaporizes and escapes the moisture in materials (generally referring to moisture or other volatile liquid components) by heating to obtain solid materials with specified moisture content.假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温泵
空气干燥机有二大类:吸附式和冷冻式。吸附式压缩空气干燥机利用变压吸附的原理，湿空气通过吸附剂时，水份被吸附，得到干空气;冷冻式压缩空气干燥机利用冷却空气，降低空气温度的原理，将湿空气中的水份通过冷凝后从空气中析出，得到干空气。
There are two categories of air dryers: adsorption and refrigeration. Adsorption compressed air dryer uses the principle of pressure swing adsorption. When wet air passes through adsorbent, water is adsorbed to obtain dry air; Based on the principle of cooling air and reducing air temperature, the frozen compressed air dryer separates the water in the wet air from the air after condensation to obtain dry air.
