Description

Technical Field

[0001] The utility model relates to the field of tea production, in particular to a tea stir-frying device used in tea production. Background Art

[0002] A tea stirrer typically consists of a heating system, a stirrer, and a control system. The heating system provides heat to ensure even heating of the tea leaves during the stirrer process. The stirrer, using components such as a robotic arm or stirrer plate, evenly stirs the tea leaves, ensuring each leaf is fully heated and processed. The control system sets and adjusts parameters such as heating temperature and stirrer speed for precise control.

[0003] As the moisture inside the tea leaves evaporates, a large amount of water vapor will accumulate in the barrel and mix with the hot air to form a complex airflow environment. This airflow environment not only affects the stir-frying effect of the tea leaves, but may also cause the surface of the tea leaves to become moist, thereby affecting the aroma and taste of the tea leaves. The moist surface of the tea leaves is prone to breeding bacteria, and tea leaves that have been in a high humidity environment for a long time are also prone to mildew or deterioration, seriously reducing the quality of the tea leaves. When the existing stir-frying device discharges the water vapor and moisture in the barrel, it often causes the temperature in the barrel to drop. This temperature fluctuation not only affects the stir-frying effect of the tea leaves, but may also cause the tea leaves to be heated unevenly, thereby affecting the overall quality of the tea leaves. In order to maintain a stable temperature in the barrel, more energy needs to be consumed for heating and insulation. Utility Model Content
