Distillation as a thermal separation process is used if the chemical composition of the vapor phase is different from the chemical composition of the liquid phase. This is mostly the case for mixtures of products having different boiling points means different volatilities. Process and plant design to separate, purify, concentrate and recover chemcial components by distillation if one of our core competences.The main equipment of distillation in industrial production is distillation tower, which is the packing of tower.

Drying equipment refers to a kind of mechanical equipment that vaporizes the moisture content (generally refers to moisture or other volatile liquid components) in the material by heating, so as to obtain the solid material with specified moisture content. It is a kind of mechanical equipment to realize the drying process of materials.

Drying equipment can be classified according to operation process, operating pressure, heating mode, wet material movement mode or structure.
