Description

Technical Field

[0001] The utility model belongs to the technical field of tea processing, and particularly relates to an infrared drying and aroma-enhancing integrated machine. Background Art

[0002] After being collected, tea leaves are dried and aromatized by a drying and aromatization machine to remove excess moisture and ensure the finished tea reaches the required moisture content. This drying and aromatization process further slims the tea leaves, improving their appearance and quality. It also releases unique aromatic compounds, creating a distinctive aroma. It also changes the color of the tea, making it brighter and the tea soup more translucent. The tea drying process also involves complex chemical reactions that reduce the tea's bitterness and enhance its flavor.

[0003] Most existing tea roasting machines or continuous dryers use hot air heating technology, which can only heat the tea leaves from the outside to the inside, often causing the tea leaves to deform during the drying process, or due to uneven heating, the tea stems are not dried thoroughly, resulting in uneven overall color of the finished product. In addition, because air is used as the medium for convection heat conduction, it takes a long time to complete the drying and aroma enhancement, and the efficiency is extremely low. In addition, most existing tea roasting machines use a layered stacking method, and only the drying screen is rotated in the drying oven. The directly heated surface is small, and the tea leaves are not turned over. If turning over is required, it must be done manually, which is inefficient. Utility Model Content

[0021] 2. It adopts a three-layer structure, which is combined together in the form of a conveyor belt. Tea is fed from the top layer and falls to the second layer by gravity. The second layer then falls to the third layer. The tea is turned over twice during the entire drying and aroma-enhancing process, making the overall dryness and moisture content of the finished tea more uniform. The turning and tossing process does not require manual intervention, which improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In the present invention, the first infrared heating tube assembly 9, the second infrared heating tube assembly 10 and the third infrared heating tube assembly 12 are all composed of multiple infrared heating tubes, SCR thyristor electrical components, thermostats and temperature sensors that are electrically connected to each other. The number of the multiple first infrared heating tube assemblies 9, the second infrared heating tube assemblies 10 and the third infrared heating tube assemblies 12 is the same as the number of the multiple insulation boxes 16, and the multiple first infrared heating tube assemblies 9, the second infrared heating tube assemblies 10 and the third infrared heating tube assemblies 12 located at the same height are connected in series.
