ZPG the special spray dryer for Chinese herbal extract is a special spray dryer. The high speed centrifugal spray device of the Chinese herbal extract is the application of the centrifugal spray drying technology in the drying of specific materials. It is also the use of high speed centrifugal atomizer to disperse the material into fog, fully contact with the hot air, complete the instant drying and form a powdery finished product. A drying device.

ZPG special dryer is specially used to solve the spray dryer of Chinese medicine extract and plant extract. The special dryer of Chinese herbal extract has been used to solve the following situation of material in the original LPG high speed spray dryer in the drying of Chinese herbal extract.

When the liquid material (through filtered liquid) is sent into a high speed rotating centrifugal atomizer, the centrifugal force of the rotating disk extends the film on the rotating surface and keeps moving to the edge, causing the material to stick to the wall, and the rate of collecting powder will be low.

When it leaves the edge, it is atomized. The droplet after atomization (the surface area is greatly increased) is exchanged with the hot air, and the drying process is completed rapidly in 10-30 seconds. If the material stays on the wall for a long time, the coking deterioration phenomenon of the material is difficult to clean and does not meet the requirement of GMP.

In summary, the production will be low, for example, the LPG-150 type spray dryer, and its output can only deal with 50-60kg/h liquid. The ZPG special dryers used for the Chinese medicine extract are completely closed, all parts are made of stainless steel, with three level purification equipment, and the filtered air reaches the one hundred thousand level. There is a cold wall device in the simple and top, which makes the temperature of the tower wall below the gas temperature of the tower is about 10 degrees C, and the material stays on the wall will not produce the coking metamorphism, which greatly increases the powder collecting rate, and does not produce the phenomenon of sticky wall.

In view of the above conditions, our factory designs a new type of Chinese herbal extract spray dryer according to the material properties and technological requirements of the extract of Chinese medicine. The dry material is well colored and does not deteriorate, which greatly improves the economic benefits of the drying equipment manufacturers.
