Work Theory:
SZG Double Conical revolving vacuum Dryer is double conical rotatihng cylinder。Under the state of vacuum in the cylinder，pass oil or hot water into the jacket to heat。The heat will be contacted with damp raw material through inner wall。The evaporated steam after the raw material absorbed heat will be exhausted through vacuum pump。Beacause the inner of cylinder is in vacuum state and the cylinder make raw material turn over from up to down and from inner to outer。the drying speed is fastened and the drying efficiency is raised and the purpose of uniform dry

can be reached。

Characteristics:

The Double Conical Revolving Vacuum Dryer is a new style dryer integrated mixing and drying in one body。It is equipped with condensator and vacuum pump。(If the solvent does not recover，the condensator may not be used)。The design of this machine is advanced and its inner structure is simple。So its clean is very convenient and the raw material can be discharged fully and its operateion is very simple。It can reduce labor strength and improve working environment。Level meanwhile when the cylinder is rotating，the raw material is rotated too，the wall of cylinder can not be accumulated on the wall。Its coefficient of thermal transmission is high and the drying speed is high。Not only it can save energy but also the raw material can be dried fully and uniformly and the quality of product is high。It can be used wide for pharmaceutical industry，chemical industry，foodstuff industry，dyestuff industry，etc。It is in conformity with the requirements of “GMP”。

Application:

◆Themal sensitive raw materials that cannot be dried at high temperature。

◆Raw materials that is easy to oxidize and have dangerous。

◆Raw materials that the solvent and toxic gases are needed to recover。

◆Raw materials that have special requirement for crystal shape。

◆Raw materials that have special requirement for the content of residual volatile。
