Key word:Comparison of Powder Rate between Special Application and High Speed Spray Drying Machine of Traditional Chinese Medicine

ZPG special spray drying machine for Chinese medicine extract is a special spray drying machine. The high-speed centrifugal spray drying device for Chinese medicine extract is an application of centrifugal spray drying technology in the drying of specific materials. It also uses high-speed centrifugal atomizer to disperse materials into fogs. Full contact with hot air, complete instant drying, forming a powder drying device.


ZPG special drying machine for traditional Chinese medicine extract is a spray drying machine that is specifically used to solve traditional Chinese medicine extract and plant extract. The special drying machine for traditional Chinese medicine extract solves the following situations where the material appears in the original LPG high-speed spray dryer in the drying of traditional Chinese medicine extract:


When the liquid(filtered liquid) is fed into a high-speed rotating centrifugal fogging disk, the acting material liquid of the centrifugal force of the rotating disk extends into a thin film on the rotating surface and continues to move toward the edge, resulting in the material sticking wall, the pollination rate will be low.

When leaving the edge, it is atomized. After the atomized droplet(the surface area is greatly increased), it is thermally exchanged with the hot air and the drying process is quickly completed within 10-30 seconds. If the material stays on the wall for a long time, The coking deterioration of the resulting materials is difficult to clean and does not meet the requirements of GMP.


In summary, this will lead to low yields, such as the LPG-150 spray dryer, which can only handle 50-60 kg / H slurry. The ZPG Chinese medicine immersion dryer adopts a fully enclosed form. All parts are made of stainless steel and equipped with a three-level purification device. The filtered air reaches the 100,000 level. Simplified and top are equipped with cold wall devices, so that the temperature of the tower wall is lower than the gas temperature in the tower reaches about 10 °C, and the material stays on the wall without coking and metamorphism, which greatly increases the pollination rate and does not produce sticky walls. phenomenon.


In view of the above conditions, I plant according to the material properties and process requirements of traditional Chinese medicine extract spray drying machine designed a new type of traditional Chinese medicine extract, dry material color is good, non-deterioration, greatly improve the economic benefits of drying equipment manufacturers.
