ZPG Spray Dryer For Chinese Traditional Medicine

Traditional Spray Dryer for Chinese Traditional Medicine (Herb Medicine)Extract normally is the centrifugal type with closed structure. All parts in contact with materials, products, and air inlet are manufactured by high-quality stainless steel. By the three-grade purification device, the filtered air could meet the 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, air sweeping or wall scraping devices can be configured correspondingly improve the yield.

Based on the early technology of home and abroad, the Spray Dryer for Chinese Traditional Medicine Extract is suitable for drying the materials that are low in melting point and high in sugar contents, and the machine owns the characteristics that its product will not stick onto the wall, uneasy to absorb the moisture, etc. The technological conditions for spray and drying are decided according to the 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 meets the GMP requirements.

According to the characteristics of product and equipment, the pressure-type Spray Dryer for Chinese Traditional Medicine Extract is newly developed to avoid wall sticking, improve product quality, simplify the process, increase the particle size and solubility of the product.

Features & Applications

1. Three-grade air purification is used to make air inlet with the cleanness of class 10,000.

2. Wall cooling device is applied to make an inner wall temperature maximum of 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. A quick washing device is adapted to fit the production requirements of various kinds.

5. A 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 the atomizer with inverter adjustment.

8. PLC control and screen display of a programmable control system.

9. Washing device as an option.

10. Dry air closed pneumatic transportation on request. We’ve developed a new pressure spray type spray dryer for Chinese Traditional Medicine. Except for the features above, it also has the following features:

11. Big particle size and good flowability of the final product.

12. Wall sticking problem is solved, and the product quality is improved

13. High quality and good solubility of the 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 the drying tower is high, and the workshop is also high, so the investment in workshop is high. It is normally applicable for high requirement products and high value-added products.

Innovation

● The tail gas is treated by wet dust remover specially designed to reduce the loss of water in the process of dust removal such as the need to further reduce the cost of the product. The purified water can be used as circulating water. When the material is collected to a certain concentration, it can be returned to the concentration process, and there is almost no loss of the material.

● The pressure measuring device in the main tower of the spray dryer can observe the operation state according to the negative pressure.

The cyclone has a pressure difference device. According to the pressure difference, it can be judged whether there is a cyclone blockage phenomenon. Likewise, according to the main tower air filter pressure difference transmitter, it can be judged whether there is a blockage filter.

With the increase of drying tower straight section, the material stay time can be prolonged, so as to improve production capacity.
