ZPG Spray Dryer (For Herb Extract)

Traditional spray dryer for Chinese traditional medicine extract is the centrifugal spray drying technology applied in the drying of specific material. High speed centrifugal type atomizer is utilized to disperse the materials into mist. After in full contact with hot air, the materials complete instant drying to form dry powder products. If we use LPG high speed centrifugal spray dryer for drying Chinese traditional medicine.

Traditional Spray Dryer for Chinese Traditional Medicine Extract normallyis centrifugal type with closed structure. All parts in contact with materials,product and air inlet are manufactured by high quality stainless steel. By thethree grade purification device, the filtered air could meet requirement of10,000 class. The wall cooling device is installed to keep temperature below80_ , so that the materials will not be coked or deteriorated even stick on the wall. The powder collecting efficiency could be highly increased (more than98-99%).

According to product characteristics and customer requirements, airsweeping or wall scraping device can be configured correspondingly toimprove the yield.

Based on the early technology of home and abroad, the Spray Dryer ForChinese Traditional Medicine Extract is suitable for drying the materials thatare low in melting point and high in sugar contents, and the machine owns thecharacteristics that its product will not stick onto the wall, uneasy to absorb themoisture etc. The technological conditions for spray and drying are decidedaccording to features and property of the products to be dried in the machine.The automation level of the dryer is high, the operation is simple and meetsthe GMP requirements.

According to the characteristics of product and equipment, the pressuretype Spray Dryer for Chinese Traditional Medicine Extract is newly developedto avoid wall sticking, improve product quality, simplify the process, increasethe particle size and solubility of product.

Low capacity: The actual capacity of LPG-150 can only treat liquid material of 50-60kg/h. Based the above situation, we have designed specialized spray dryer for Chinese traditional medicine. The product after drying has good color and quality. Compared with LPG, it has following features: 

1.  Three-grade air purification is used to make air inlet with cleanness of class 10,000.
2. Wall cooling device is applied to make inner wall temperature maximum 80_ , so that the material will not get coking on the wall.
3.  The volumetric capacity is 3.5 around times of normal LPG.
4. Quick washing device is adopted to fit production requirement of various kinds.
5. Wet scrubber is used to ensure no loss of dust, which meets the environmental protection requirements.
6.  Air sweeping device is used.
7. Two sets of atomizer with inverter adjustment.
8. PLC control and screen display of programmable control system.
9. Washing device as option.
10. Dry air closed pneumatic transportation on request. We’ve developed new pressure spray type spray dryer for Chinese Traditional Medicine. Except the features above, it also has the following features:
11. Big particle size and good flowability of final product.
12. Wall sticking problem is solved, and the product quality is improved
13. High quality and good solubility of product.
14.  The configuration is simple and the operation is simple. 
15. The structure is simple and maintenance cost is low. The main disadvantage of pressure spray type is higher investment cost, mainly because of the drying tower is high, and workshop is also high, so the investment on workshop is high. It is normally applicable for high requirement product and high value-added product.
