For a long time, the spray drying of laboratory spray dryers on some materials, such as laboratory Chinese medicine (Chinese herbal medicine) natural product extracts and fruit juices, often causes sticking problems, which is a big problem for researchers. Conventional实验室spray dryers, when spray-drying natural product extracts and fruit juices of laboratory Chinese medicine (Chinese herbal medicine), because the material itself contains many sugar components, the sugar is relatively easy to melt at high temperature, and the It melts and sticks together to form something like brown sugar. It sticks to the wall of the bottle in the spray drying room of the spray dryer. The scientific research personnel cannot get the powder with good fluidity. Sometimes in order to obtain the powder, a large amount of auxiliary materials such as starch are added , Cyclodextrin or something, but the effect is not very satisfactory. When using Shanghai Yacheng Instrument Equipment Co., Ltd. YC-1800 laboratory low temperature spray dryer for spray drying, you use an inlet air temperature of 105 ° C, the sugar in the material will not melt, and there will be no sticking problem The powder particles with excellent fluidity and high yield are obtained, which is an excellent choice for spray drying of Chinese medicine (Chinese herbal medicine), natural product extracts and fruit juices.
