AI Technical Summary

Technical Problem

Traditional Chinese medicine decoction piece drying equipment suffers from uneven hot air circulation, local overheating, and insufficient drying, resulting in loss of effective ingredients and risk of mold growth. It also has low heat energy utilization and is difficult to meet the needs of large-scale production.

Method used

The closed-loop hot air circulation design, combined with the air collection hood and impeller, enables uniform diffusion and reuse of hot air. The design of the rotating disc and feeding/discharging components enables dynamic tumbling and uniform heating of the medicinal slices.

Benefits of technology

It solves the problem of uneven temperature distribution, improves heat energy utilization, shortens the drying cycle, ensures the preservation of effective components in medicinal slices, reduces the risk of mold growth, and meets the needs of large-scale production.
