The spray dryer of traditional Chinese medicine extract combines the spray drying technology and the special requirements of traditional Chinese medicine treatment. By atomizing the traditional Chinese medicine extract and contacting it with hot air, the water can be quickly evaporated to obtain dry and delicate traditional Chinese medicine powder. This device has the advantages of high production efficiency, stable product quality, and easy operation, and is an important tool in the modern production of traditional Chinese medicine,
What is the working principle of the spray dryer for Chinese herbal extracts? as shown below
1. Pretreatment stage: pump the Chinese herbal extract into the liquid tank of the spray dryer. At this stage, it may be necessary to carry out appropriate pretreatment on the extract, such as adjusting the viscosity, temperature, etc., to ensure that the base is suitable for spray drying
2. Atomization stage: The paste is atomized into tiny droplets by a high-pressure pump or centrifugal atomizer. These droplets are uniformly dispersed under the action of a high-speed rotating atomizing disc or high-pressure airflow.
3. Drying stage: The atomized droplets are thoroughly mixed with preheated hot air in the drying chamber. Hot air provides the necessary heat to rapidly evaporate the moisture in the droplets. As the water evaporates, the traditional Chinese medicine ingredients gradually concentrate and solidify into powder.
4. Collection stage: The dried traditional Chinese medicine powder is not separated and collected by collection devices such as cyclone separators or bag filters. The collected powder has high purity and uniform particle size distribution,
