[0002] Through drying, the traditional Chinese medicine extract can protect the active ingredients of traditional Chinese medicine while being convenient for storage and transportation. Through drying, concentration can be achieved, the content of water and other impurities in the extract can be reduced, and the active ingredients in traditional Chinese medicine can be protected from being damaged. Existing traditional Chinese medicine extract drying devices, such as a spray drying device for preparing traditional Chinese medicine extract disclosed in the application number CN202320109194.3, through the setting of multi-layer drying, deepen the evaporation of water, make the drying of traditional Chinese medicine extract more thorough, through the setting of upper and lower series connection, ensure the coherence of the drying of traditional Chinese medicine extract, and through the setting of atomizing nozzles evenly distributed on the circumference of the bottom of the liquid distribution plate, increase the dosage of primary atomizing drying of traditional Chinese medicine extract.

[0003] However, during actual drying, the drying device in the existing technology has a complex structure. In order to ensure that the atomized traditional Chinese medicine liquid can fully contact with hot air, the cross-sectional area of the drying chamber used is often small, resulting in low efficiency of drying the traditional Chinese medicine liquid extraction. Moreover, with a fixed centrifugal atomizing nozzle, there are problems of uneven spraying and inability to evenly disperse the traditional Chinese medicine liquid, which easily affects the full contact between hot air and the atomized traditional Chinese medicine extract, causing problems of incomplete and insufficient drying. Especially, the direct discharge of the hot air and water vapor after drying easily causes heat energy loss and increases the use cost. Therefore, we propose a traditional Chinese medicine extract drying device to solve the above problems. Content of the Utility Model
