1. General description
 Chinese medicine extract is refined from  root, stem and leaves of plants, and contains high sugar especially from  alcoholization process, which is easy melted at high temperature. Normal  centrifugal spraying can not meet its drying requirements. For that reason, our  company organized a group of technicians to develop such a dryer especially  used for Chinese medicine extract after repeated calculations and countless  tests on the basis of our experience to make spraying dryer and collect  advantages of same kind of dryers from both domestic and abroad. And this  equipment is widely used by many famous pharmaceutical factories. ZLPG-5  Centrifugal Spray is a laboratory model equipment for R&D, and is favored  by customers.

2. Features of the equipments
 1. The diameter and height of the tower have be modified to ensure that powder  cannot reach at the wall of the tower before drying, and ensure that powder  will have enough dwelling time in hot air. And can choose sir sweep system to  clean the powder that stick on the inner wall. 
 2.All contact places inside the dryer have plain or round surface, and are  ground and polished(fine polish over 10) to avoid sand hole and dead angle etc.  The contact surface is made of stainless steel to ensure materials free of  pollution. The driving parts have good sealing to prevent water and oil.  Material discharge is done by sealed butterfly valve to avoid air leaking.  Discharge pipes are connected flexibly for easy dismantling in order.
 3. Three-stage air filters are used on air pre-treatment system and air can be  purified up to 100 thousand level。 
 4. PLC Program control system circuit is used and cartoons of touch screen  display technological process. Variable data carries out automatic trace and  regulation by fuzzy technique, the atomizer is adjusted stably by inverter,  temperature of inlet air is adjusted by the power-regulator, precision can  teach plus and minus two so as to largely reduce energy consumption. Inlet and  outlet temperature as well as inside the tower can be set up precisely.
