The LPG-150 Centrifugal spray dryer for drying Chinese medicine extracts has been delivered

The LPG-150 Centrifugal spray dryer that made by our company has been delivered to domestic client. The spray dryer is used for drying Chinese medicine extracts.

Chinese herbal 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 herbal 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 the equipment is widely used in many famous pharmaceutical factories.

Features of our spray dryer for Chinese medicine extracts:

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 to complete low-temperature drying. The wall of the tower has sandwich cooling device to ensure liquid materials not to be softened, melt or coked when they are stuck on the wall that has partial high-temperature. There is air shocker on the cone body which has larger taper and can pulsate the tube by compressed air to shake down powder which is stuck on the tube. 
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. Discharging system adopts advanced freezing dehumidifying system, it solves the problems of blocking, soften and moisture absorption.

5. The pipe from main tower to cyclone separator is made of SUS304/316L, it is once-molded smooth stainless steel pipe, so there is no powder packed there. And it adopts quick-open type, it’s easy to discharge sewage when cleaning.
6. 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.
