[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea tree. Tea leaves are oblong or oval in size and can be brewed directly with boiling water. They are divided into six categories according to the variety, production method and product appearance. According to the season of harvesting, they can be divided into spring tea, summer tea, autumn tea and winter tea.

When unloading, the tilted setting allows the tea leaves and tea debris to slide into the active channel below with gravity to achieve unloading. The energy-saving tea drying equipment can heat the heating pipe in the insulation barrel to indirectly dry the tea in the storage barrel. However, the heating pipe is in the upper half of the insulation barrel, so when filtering tea debris, the debris will not affect the heating pipe. The fan directly blows air in the early stage to blow away most of the moisture and part of the heat to achieve low-temperature drying. In the middle and late stages, the three-way valve is switched to achieve air circulation. At this time, heat is not lost, and drying with greater heating efficiency is achieved. More thorough drying is achieved. In this process, the desiccant bag can dehumidify to ensure thorough drying. The design of the support plate makes it easy to take away the support frame and the desiccant bag. The design of the grille ensures the normal flow and circulation of air. The energy-saving tea processing drying equipment can stir and dry the tea leaves well without damaging them. BRIEF DESCRIPTION OF THE DRAWINGS
