Normal drying equipment because unlike the last few step-outs will result in quality of the finished particles, the particles making time. Pharmacy workers carried out extensive experimental study. If the granulation process, the staff through the selection of better materials and improved process conditions to improve grain quality, improve its properties.
In accessories, in addition to sugar,oil extraction, soluble starch, but also use maltodextrin, lactose, microcrystalline pelleting machine, silica powder, hydroxypropyl starch, etc.; in the process changed the traditional process drying time is long, herbs more loss of heat labile component shortage, the use of dynamic extraction, low-temperature vacuum drying or spray drying instant, dry granulation, new technologies such as high-speed agitation granulation.
