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.
