ZLG series Chinese medicine extract spray dryer
The machine is fully enclosed, all parts are made of stainless steel, equipped with a three-stage purification device, and the filtered air reaches the 100,000-class requirement. The cylinder is equipped with a cold wall device so that the wall temperature is <80 ° C and the material is on the wall. It does not coke and metamorphize during the stay, which greatly increases the powder collection rate (over 95%), and does not produce mixed drugs and sticky walls.
The traditional Chinese medicine extract high-speed centrifugal spray device is the application of centrifugal spray drying technology in the drying of specific materials. It is also the use of high-speed centrifugal atomizers to disperse the materials into a mist, fully contact the hot air space, and complete instant drying to form a powder. Finished drying device.
The special dryer for traditional Chinese medicine extract is a spray dryer specially used to solve the problem of traditional Chinese medicine extract and plant extracts. It solves the following situations in the drying of traditional Chinese medicine extract in the original LPG high-speed spray dryer :
1. The material sticks to the wall and the powder collection rate is low;
2. The material stays on the wall for a long time, resulting in the phenomenon of coking and deterioration of the material
3. It is difficult to clean and does not meet GMP requirements;
4, low output: LPG-150 spray dryer , its output can only handle 50-60kg / h feed liquid.
In view of the above conditions, our factory designs the traditional Chinese medicine extract dryer according to the material properties and process requirements of the traditional Chinese medicine extract. The dried material has good color and does not deteriorate, which greatly improves the economic benefits of the factory. Compared with spray dryer , it has the following characteristics:
1. Three-stage air purification is adopted to make the inlet air reach the level of 300,000;
2. The cold wall device is used to make the inner wall temperature reach 80 ° C, and the materials stay on the wall without coking;
3. The whole volume is 3.5 times of the original LPG standard centrifugal spray.
4. Quick opening flushing device is adopted, suitable for multi-variety production requirements
5.Dust removal adopts wet dust removal, so that the dust does not go out and meets environmental protection requirements;
6, the use of air-sweep device, the effect is more satisfactory;
7. Provide 2 atomizers and adopt frequency conversion speed regulation
8. PLC control is adopted, and the screen of the program control system is displayed;
9, can be equipped with washing device
10, can be equipped with dry air sealed closed transportation;
1. The tower has a cold wind jacket;
2. The tower is equipped with an automatic rapping device;
3. Tower body and pipeline are equipped with quick-open cleaning holes and sewage holes;
4, can be equipped with automatic control constant temperature feeding tank;
5, can be equipped with manual high-pressure washing tower random accessories;
6. The parts in contact with the material are made of stainless steel; (or all stainless steel)
7. Material collection adopts two-pole cyclone dust removal device, or one-stage cyclone dust collector and wet dust collector;
8. Automatic control and continuous device for inlet air temperature.
9. Can be equipped with air sweep device.
