AI Technical Summary
Existing tea drying equipment does not allow for uniform heating of tea leaves within the drying chamber. This results in tea leaves near the heat source being over-dried due to continuous high temperatures, while tea leaves further away from the heat source are not dried sufficiently, affecting the overall drying quality.
A tea drying device for processing was designed, which includes a circulation section and a cleaning section. The circulation section uses spiral blades to drive the tea leaves to circulate in the drying chamber, and the cleaning section uses scrapers to scrape off the tea leaves adsorbed on the inner wall, ensuring that the tea leaves are heated evenly and preventing local over-drying or insufficient drying.
This method achieves uniform heating of tea leaves within the drying chamber, preventing aroma loss or flavor deterioration caused by localized over-drying. It also prevents tea leaves from scorching due to prolonged contact with the high-temperature inner wall, preserving the color, aroma, and flavor of the tea leaves, while improving drying efficiency and environmental cleanliness.
