In general, drying a solid means the removal of relatively small amounts of water or other liquid from the solid material to reduce the content of residual liquid to an acceptably low value. Drying is usually the final step in a series of operations, and the produce from a dryer is ofen ready for final packing.
Water or other liquids may be removed from solids mechanically by filtration or centrifugation or thermally by vaporization. It is generally cheaper to remove water mechanically than thermally. The utmost use should be made of these mechanical processes. In a simple instance a centrifugal will remove 2 tons of water from a ton of granular solid with a power cost of about 10 kwh;the steam equivalent of this will be at most 300 lb. If the water is evaporated in a steam-heated dryer, the steam consumption must be at least 4,480 lb. Thus it is advisable to reduce the moisture content as much as possible before feeding the material to a heated dryer.

一般来说，烘干了坚实指由固体物质的水或其他液体相对少量的清除，以减少残留液体的内容可以接受的低价值。干燥通常是在一连串行动的最后一步，从一个机生产的奥芬准备最后的包装。
水或其他液体可能会被删除从固体机械经过滤或离心或汽化热。一般较便宜，消除水热机械。最应利用这些机械过程。
在一个简单的实例离心将取消对颗粒约一○千瓦时电力成本固体;本蒸汽将收取最多三百英镑如果水蒸发的蒸汽加热干燥吨2吨水，蒸汽消耗必须至少四千四百八十○英镑因此最好是在喂养前减少材料的加热烘干水分尽可能。
一个德里德物质的水分含量不同，从产品到产品。有时，产品不包含水。更普遍的，该产品确实含有一些水。干食盐，例如，包含了大约百分之0.5的水，干煤约百分之一4，干约百分之8酪蛋白。
干燥是一个相对的概念和方法，只是有一种水分含量由初始值减少到最后一个。
