干燥，特别涉及固体材料或从溶液、浆料或悬浮液中单步生产固体材料，通常被理解为通过热手段去除水分，并且只有当水分的蒸汽压大于其在周围环境中的分压时才能发生。如果这两个压力是相同的，再多的能量应用将促进干燥。提供能量的目的是(i)提高湿气的温度，使其蒸汽压高于其环境分压，（ii）为汽化和产生的蒸汽的任何显热要求提供能量。任何材料必须提高到的最低温度取决于湿气的环境分压，而最高温度则受材料对不利热效应的敏感性的限制。从广义上讲，干燥可以看作是一个物料处理问题，干燥机的主要选择通常基于原料的物理性质。
Drying, with particular reference to solid materials or the single-step production of solid materials from solutions, slurries or suspensions, generally, is understood to concern the removal of moisture by thermal means and can occur only when the moisture's vapor pressure is greater than its partial pressure in the surrounding environment. If these two pressures are identical, no amount of energy application will promote drying. The purpose of supplying energy is (i) to raise the temperature of the moisture so that its vapor pressure is above its ambient partial pressure, and (ii) to provide energy for vaporization and any sensible-heat requirement of the generated vapor. The minimum temperature to which any material must be raised depends on the moisture's ambient partial pressure and the maximum temperature is limited by the material's susceptibility to adverse thermal effects. In a broad sense, drying may be viewed as a materials-handling problem, with primary selections of a dryer ordinarily based on the physical nature of the feedstock,
