The machine adopts full close structure with primary middle and high effect air filter to fit one hundred thousand grade requirement, the tower body is provide cooling air jacket to make wall temperature less than 80 degree, when the material stops on wall will not to be preheated and softened, it increases the powder collection rate (95%) and will not appear mixing and sticking wall phenomenon.
Basic principle: High Speed centrifugal atomizing for the extract of traditional Chinese Medicine is an application of centrifugal atomizing technique. It also uses high-speed atomizer to make liquid material into foggy droplet to contact with hot air fully to finish instant drying and get final powder products.
The ZPG Chinese Herb Extract Spray Dryer is specially designed to solved the problems which previous LPG spray dryer meets during drying herb extract and plant extract products as follows:
1) Raw material sticks to wall and powder collection rate is low.
2) Raw material stays on wall for long time, resulting in coking and deterioration phenomenon.
3) It is difficult to clean and can not meet GMP requirement.
4) Low in output: LPG-150 type dryer can only process 50-60kgs/h of raw material liquid.
