AI Technical Summary
In tea processing, the accumulation of tea leaves during hot air drying leads to uneven heating of the tea leaves inside. Tea leaves near the hot air inlet dry quickly, while tea leaves far from the hot air inlet or inside the tea pile may not dry completely.
The tea-stirring component and air supply duct design are adopted. The stirring component stirs the tea leaves with a turntable and blades to make them evenly distributed, and the air supply duct with a spiral structure delivers air in reverse to ensure that each tea leaf is heated evenly.
This process achieves uniform dehydration of the tea leaves, improves the drying effect, and creates a tightly rolled shape through stir-frying and counter-current airflow, thus enhancing the aroma and taste of the tea.
