Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea-drying device for spreading and drying tea leaves. Background Technology

[0002] Withering is an important step in tea production. Its main purpose is to further reduce the moisture content of tea leaves through natural air drying, thereby improving the quality and taste of the tea. Withering usually takes place after sun-drying. The tea leaves are placed in a well-ventilated area and allowed to air dry naturally to further reduce their moisture content. This process is often repeated multiple times. Withering devices based on tea spreading are mainly used to remove moisture from the tea leaves after picking by spreading and ventilating them, while preserving their fresh aroma and color.

[0003] Existing tea-drying devices are not easy to stably support the drying racks in actual use, which can easily cause tea leaves to scatter and potentially cause personal injury.

[0004] A search of existing patents revealed an automatic tea-drying device (publication number: CN214015796U), comprising a base plate. Several supports are evenly fixed on both sides of the upper end of the base plate. Gears are movably mounted on the upper ends of the supports via rotating shafts. A rotating disk is fixed on the side of the gears away from the supports. Telescopic rods are fixedly mounted on the upper and lower ends of the rotating disk. A first fixing block is positioned between the rotating disks. A second fixing block is movably mounted on the lower end of the first fixing block via a hinge. A first drying net is fixed between the first fixing blocks, and a second drying net is positioned between the second fixing blocks. This invention offers good performance. During drying, the tea leaves are placed between the first and second drying nets. Simply flipping the first and second drying nets flips the entire tea leaf sandwiched between them, making drying convenient and quick to use.

[0005] While the aforementioned patent allows tea leaves to be stored between the first and second drying nets during the drying process, making it convenient and quick to use, it does not facilitate easy access or storage on high drying racks or optimize space, thus hindering work efficiency.

[0006] Therefore, it is necessary to invent a tea-based drying device to solve the above problems. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides a tea-withering device based on tea leaf spreading, which has the following beneficial effects:

[0019] 1. This tea-drying device, through the setting of lifting components and drying racks, allows for easy access to and storage of tea leaves at higher locations. When a higher drying rack needs to be removed, the lower drying rack is first removed. Then, the drive motor is activated, causing the rotating shaft to rotate on the inner wall of the support frame. This rotating shaft then drives the conveyor belt to rotate inwards, causing the positioning plates and support rods to descend, thus lowering the higher drying rack. When the drying rack needs to be placed, the drive motor is activated, causing the rotating shaft to reverse, causing the conveyor belt to rotate outwards, thereby raising the drying rack. This facilitates easy access to and storage of tea leaves at higher locations, allowing workers to quickly and easily retrieve or store tea leaves, reducing operation time, fully utilizing vertical space, and improving work efficiency.

[0020] 2. This tea-drying device, through the setting of positioning components, aligns the threaded holes on the support plate and positioning plate during installation, and then uses threaded bolts for fixing. At the same time, when placing the drying rack, align the connecting plates on both sides of the drying rack with the support rod, and then insert the positioning pin on the support rod into the insertion hole on the connecting plate to fix the position of the drying rack. This achieves the effect of stable support for the drying rack, and makes it easy to handle. It also ensures that it will not tip over or shake during use, avoids tea scattering and possible personal injury, and ensures operational safety. Attached Figure Description
