Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tea drying, in particular to tea drying equipment. Background Art
[0002] Tea processing refers to the process of making finished tea after the fresh leaves of tea trees are harvested through various processes. For example, the processing technology of green tea is withering, rolling, and drying; the processing technology of black tea is withering, rolling, fermentation, and drying. Tea drying is the last process of tea processing. Its main purpose is to lose the moisture of tea leaves, shape tea leaves, and increase the aroma of tea leaves. The quality of drying directly affects the quality of tea leaves. In the process of tea processing, the tea leaves are driven to circulate through the tea drying equipment so that the surface of the tea leaves can be evenly dried, which is conducive to improving the flavor of the finished tea leaves.
[0003] At present, many tea drying equipment cannot perform multi-level screening of tea leaves, and cannot screen some broken leaves, broken leaves, and residual leaves well. Therefore, some broken leaves with large particle sizes will be mixed in the complete tea leaves, resulting in the overall low quality of the tea leaves leaving the factory. If manual screening is performed after drying, a lot of human resources will be wasted, thereby reducing processing efficiency. In addition, most drying equipment only has one drying port or drying direction, resulting in poor drying effect and efficiency. Utility Model Content

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Embodiment 1:
[0023] See also Figures 1 to 5The utility model provides a technical solution: a tea drying device, including a drying device body 1, a main discharge door 2 is installed on one side of the drying device body 1, a blower 9 and a heating box 10 are fixedly installed on the upper surface of the drying device body 1, the air outlet of the blower 9 is connected to the interior of the heating box 10, and a heating wire 11 is electrically arranged in the heating box 10, and a first screening box 5, a second screening box 6 and a third screening box 7 which are interconnected and used for layer-by-layer screening are arranged in the drying device body 1, the upper surface of the drying device body 1 is connected to the first screening box 5 and a feeding pipe 8 is arranged inside, and the center of the drying device body 1 An insulation box 3 is fixedly installed on the inner bottom wall, and a motor 4 is electrically arranged inside the insulation box 3. The output shaft of the motor 4 is fixedly connected to the bottom of the third screening box 7. The drying equipment body 1 is located on both sides of the first screening box 5, the second screening box 6 and the third screening box 7, and heating pipes 12 connected to the heating box 10 are symmetrically arranged. The tube walls of the heating pipes 12 are evenly connected and provided with a number of heating ports 13. The surfaces of the first screening box 5, the second screening box 6 and the third screening box 7 are all hingedly limited with a discharge door 19, and the box surfaces of the first screening box 5, the second screening box 6 and the third screening box 7 are evenly spaced with slots 14 for drying.
[0024] More specifically, in this embodiment, first, the operator slowly pours the tea leaves into the first screening box 5 in the drying equipment body 1 through the feed pipe 8, starts the motor 4 in the insulation box 3 and the blower 9 and the heating box 10 on the drying equipment body 1, and the output shaft of the motor 4 drives the first screening box 5, the second screening box 6 and the third screening box 7 to rotate to screen the tea leaves, effectively achieving the layer-by-layer screening effect in the rotary drying process, ensuring the dual functions of drying and screening of the tea drying equipment, and improving the work efficiency of tea processing.
[0025] The blower 9 transmits the wind to the heating box 10. After being heated by the heating wire 11, the wind will pass through the drying pipes 12 on both sides, and be evenly dispersed from the drying port 13, and evenly pass through the slots 14 of the first screening box 5, the second screening box 6 and the third screening box 7 to dry the screened tea leaves inside. This not only ensures the uniformity of drying, but also expands the area dried by the drying wind, thereby improving the drying efficiency and effect of the tea drying equipment.
