When the liquid material (filtered liquid material) is sent to the high-speed rotating centrifugal atomizing disk, the material liquid is stretched into a film on the rotating surface by the centrifugal force of the rotating disk and continuously moves to the edge, resulting in sticky walls and powder collection rate It will be low.
When it leaves the edge, it is atomized. After the atomization, the droplets (the surface area is greatly increased) exchange heat with hot air and quickly complete the drying process within 10-30 seconds. If the material stays on the wall for a long time, it will produce material. Coking deterioration is difficult to clean and does not meet GMP requirements.
In summary, the output will be low. For example, the LPG-150 spray dryer can only handle 50-60kg / h of feed liquid. The ZPG Chinese medicine extract dryer 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 level requirement. A cold wall device is installed at the top, so that the temperature of the tower wall is lower than the temperature of the gas in the tower by about 10 ° C, and the material will not cause coking and metamorphism when it stays on the wall, which greatly increases the powder collection rate and does not cause sticky walls phenomenon.
In view of the above situation, our factory has designed a new type of Chinese medicine extract spray dryer according to the material properties and process requirements of Chinese medicine extract. The dried materials have good color and do not deteriorate, which greatly improves the economic benefits of drying equipment manufacturers.
