Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea sterilization and aroma-enhancing device. Background Art

[0002] Tea is easily contaminated by bacteria and mold during the growth and processing process. In order to prevent tea contamination from affecting the taste and quality of tea and endangering human health, and at the same time to maintain the taste of tea and improve the aroma and color of tea, it is usually necessary to sterilize and enhance the aroma of tea.

[0003] Existing tea sterilization and aroma enhancement devices usually place a drying plate in an oven and heat and dry it with hot air. The tea leaves close to the source of the hot air will be heated first and usually receive greater heat, which in turn affects the aroma enhancement of the tea leaves. Although hot air is used for drying, some bacteria cannot be disinfected, reducing the sterilization effect of the device. Utility Model Content
