Description

Technical Field

[0001] The present invention relates to the technical field of integrated tea screening and drying, and specifically to a low-energy consumption integrated tea screening and drying machine. Background Art

[0002] Tea screening equipment mainly includes various stalk picking machines, such as stepped stalk picking machines, electrostatic stalk picking machines, optoelectronic stalk picking machines, and pneumatic stalk picking machines, etc. These devices are used to pick out tea stalks, veins, and other sundries in tea to improve the tea purity. There are various types of tea drying equipment. According to the heat transfer principle, it can be divided into three categories: convection, conduction, and radiation. Commonly used ones include bucket dryers, mesh belt dryers, chain plate dryers, cylindrical roasting dryers, multi-angle glow dryers, and far-infrared flavor enhancing machines, etc. These devices destroy the activity of oxidase in tea through high temperature and evaporate the moisture in tea to achieve the purpose of drying.

[0003] However, there are certain disadvantages in the non-integration of tea screening and tea drying equipment. Since the functions of the two are independent, they need to be purchased and installed separately, which not only increases the equipment cost but also occupies more space. In addition, during the tea processing process, it is necessary to transfer between the screening and drying links, increasing the labor and time costs, and also increasing the risk of tea damage.

[0004] However, even if the existing technology integrates tea screening and tea drying equipment, the problem of high energy consumption is still difficult to avoid. The screening equipment needs to consume electric energy to drive the stalk picking mechanism during operation, while the drying equipment requires a large amount of heat energy to evaporate the moisture in tea. Although the integrated equipment may be more convenient to operate, the total energy consumption is not reduced. On the contrary, due to the usually more complex integrated equipment, its maintenance and operation costs may also be higher. In addition, the high temperature and long-time heating during the drying process not only consume a large amount of energy but may also have a certain impact on the quality of tea. Therefore, in the tea processing process, how to reduce energy consumption and improve energy utilization efficiency is still an urgent problem to be solved. Summary of the Invention
