Pharmacy Spray Dryer

Description

The spray dryer with PSD drying system is mainly used for material drying such as traditional Chinese medicine, chemical products and some other materials featuring bad heat sensitivity, bad drying performance, low softening point, strong moisture absorption.

This dryer adopts high speed centrifugal atomizer to disperse the material into fog, so that the material can fully contact with hot air. Thus the material will be dried instantly and you will get powder products.

Main application

Food drying
Sugar drying
Medical products drying
Chemical product drying etc.

The following are some existed spray dryers with PSD drying system, you can choose according to your requirements. Jiangsu Xiandao can also make some improvements on the base of the following type:

Features The spray dryer with PSD drying system adopts fully enclosed appearance. All parts are made of stainless steel. This dryer is equipped with 3-stage purification plant. The filtering finished air can meet 100K cleanliness standard. The dryer tower is equipped with wall cooling device so that the wall temperature can be ＜80℃. So there will be no material coking when the material is resting on the wall. The powder collection rate can be up to 95% without phenomenon of material mixing and sticking on the wall. Main components
