中文译文
干燥技术Drying Technology(中文2100字,英文1700字)
主要有三种气体悬浮烘干:
喷雾干燥器,把液体溶液或悬浮于干燥,自由流动的粉末
流化床干燥机,用干,湿滤饼,或浆和污泥干产品再循环
闪蒸干燥机,在相当干燥,松软,非饲料粘粘
该型干燥器选择任何特定应用取决于双方的饲料性能和产品的要求. 重要饲料性能是水分含量,固形物,粘度,密度,以及任何挥发性,易燃或有毒成分. 木片产品规格可能包括平均粒度分布,密度,含水率,残留挥发或溶剂. 粉末特性可控制粉末特性保持不变,通过连续运行.

英文原文
Drying Technology
There are three main types of gas-suspension dryers:
•    Spray dryers, to convert a liquid solution or suspension to a dry, free-flowing powder
•    Fluid-bed dryers, used to dry wet filter cake, or for pastes and sludges with dry product recirculation
•    Flash dryers, for a relatively dry, crumbly, non-sticky feed
The type of dryer chosen for any given application depends on both the feed properties and product requirements. Important feed properties are the moisture content, solids, viscosity, and density, as well as any volatile, flammable, or toxic components. Dried product specifications may include average particle size and particle size distribution, density, moisture content, and residual volatiles or solvents. Powder characteristics can be controlled and powder properties maintained constant through continuous operation.
