the spray drying technology is the most employed process to produce dried extracts from medicinal plant liquid extracts. these powders need to meet certain physicochemical e.g., moisture content, hygroscopicity, particle size, density, the concentration of active ingredients and mechanical e.g., flowability and compressibility properties
Our products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
the spray-drying process, shown in fig. 1, is a well-established unit operation in the pharmaceutical industry 1. to manufacture an sdd, a spray solutionwhich consists of api and polymer dissolved in a common solventis delivered to an atomizer inside a spray-drying chamber
