Abstract: Objectives The current literature has a method of drying golden lotus, and the optimal drying process is screened for later research. Methods The sensory quality (appearance, color, odor), energy consumption (unit energy consumption, drying time, total drying time), active ingredients (total flavonoid content, polysaccharide content) were obtained by three methods for hot air drying and microwave drying equipment.
The three drying methods of vacuum freeze drying were compared to select the optimal drying process of A. chinensis. Conclusion Based on the above three evaluation results, the vacuum microwave drying method is the most suitable drying method.

Drying is an old and new traditional Chinese medicine processing and storage method. In the early days of human beings, we learned how to treat Chinese herbal medicines by drying and drying. The ultrasonic drying and solar drying in modern times are more advanced. At present, hot air drying, vacuum freeze drying, vacuum microwave drying, spray drying, etc. have become the mainstream method for drying Chinese herbal medicines.
