Problems solved by technology

Although the method disclosed in CN107397787A is simple and easy to operate, because patchouli contains various alcohols, ketones, glycosides and other components, the viscosity of the feed liquid is relatively large, causing the liquid to stick to the tower during the spray drying process, which is not only serious It will affect the efficiency of spray drying, and will also lose some materials and reduce the yield of dry paste powder

Abstract

The invention relates to the technical field of production of traditional Chinese medicine granules, in particular to an improved spray drying technology for herba pogostemonis formula granules. By means of the spray drying method, specific accessory ingredients are especially adopted, the using amount of the accessory ingredients in the formula granules can be controlled, the taking dose of a patient can be reduced, and moreover, the phenomenon that the granules adhere to a tower in the spray drying process can be greatly improved. The dry paste yield of the herba pogostemonis formula granules in the spray drying process is greatly improved.

Description

technical field [0001] The invention relates to the technical field of production of traditional Chinese medicine formula granules, in particular to an improved spray-drying method of patchouli formula granules, and belongs to the technical field of traditional Chinese medicine production. Background technique [0002] Traditional Chinese medicine formula granules are granules made by extracting and concentrating single-flavored Chinese medicine decoction pieces, and are used for clinical formulas of traditional Chinese medicine.
