Abstract
Description
Technical Field
[0001] The utility model relates to the field of tea manufacturing equipment, in particular to a light-assisted tea withering machine. Background Art
[0002] Withering is an important process in tea manufacturing. Generally, the fresh leaves are spread out at a certain thickness and dried in the sun to make them wilt. During the withering process, the fresh leaves undergo a series of changes: the moisture content decreases, and the leaves become soft from brittle and hard, making them easier to roll into strips; the activity of enzymes contained in the leaves increases, which promotes the decomposition and transformation of fresh leaf components such as starch, protein, and insoluble protopectin, generating effective substances such as glucose, amino acids, and soluble pectin that are beneficial to the quality of finished tea, and polyphenols are also oxidized to varying degrees. Existing tea withering equipment mainly achieves the withering process of tea leaves through hot air, infrared, or a combination of the two. In recent years, there have also been many uses of red light, blue light, yellow light, UV-B and other light sources to assist in the withering of tea leaves, in order to improve the efficiency of tea withering and the quality of finished tea products. Specifically, the tea withering device based on LED light source disclosed in the Chinese utility model patent with authorization announcement number CN204616947U is fixedly suspended, inconvenient to move and poor in flexibility of solution setting, which is obviously difficult to adapt to the current production needs of tea companies in the production of different teas of the same type or even different types of tea. And the array-type interval arrangement of red and blue light structure disclosed in the Chinese invention patent with authorization announcement number CN105394206B, although it has improved the flexibility of the equipment to a certain extent, with the improvement of consumption upgrades and the requirements for tea quality, different teas may involve different combinations of red light, blue light, yellow light, UV-B and other light sources in the existing tea withering, and the flexibility of this solution is obviously still insufficient.

The positioning grooves 12 are U-shaped groove structures with their openings facing the side of the withering trough 1. Each power supply seat 13 is arranged directly below the corresponding positioning groove 12. The positioning grooves 12 are mainly used to position the above-mentioned light-assisted module 5 after it is assembled and limit its movement. Therefore, it is preferred that the positioning grooves 12 and power supply seats 13 are evenly distributed along the length direction of the withering trough 1. This specific implementation method takes the 7-meter withering machine commonly used by the applicant as an example, and 14 positioning grooves 12 and 14 power sockets 13 are evenly distributed on the side thereof.
[0025] refer to Figure 1 , Figure 2 , Figure 3, the above-mentioned light-assisting module 5 can be detachably assembled on the two above-mentioned slide grooves 11, and the light-assisting module 5 extends along the width direction of the open top surface of the withering groove 1, and both ends of the light-assisting module 5 can be moved and assembled along the length direction of the slide groove 11. The above-mentioned light-assisting module 5 is a light-assisting module 5 with a withering-assisting light source on the bottom surface. The withering-assisting light source located on the bottom surface of the light-assisting module 5 can specifically be a structure such as LED, and one light-assisting module 5 has multiple withering-assisting light sources, and the multiple withering-assisting light sources are arranged in an array on the bottom surface of the light-assisting module 5. The above-mentioned withering-assisting light sources include red light sources, blue light sources, yellow light sources, and UV-B light sources; each of the above-mentioned light-assisting modules 5 is provided with a withering-assisting light source. That is, in actual applications, according to the actual needs such as the number of light-assisting tea withering machines and the types of commonly used withering-assisting light sources, a number of various light-assisting modules 5 can be prepared as accessories, and when used, they can be combined and assembled into the light-assisting tea withering machine according to the production needs of the light-assisting tea withering machine.
[0026] refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , both ends of the bottom surface of the optical auxiliary module 5 are provided with sliders 51, and the sliders 51 are provided in an inverted T-shaped structure. The sliders 51 are assembled into the slide groove cavity 111 by the end through which the slide groove 11 passes, and the inverted T-shaped structure of the sliders 51 is embedded in the slide groove cavity 111 and can be slidably arranged along the slide groove cavity 111. As shown in the figure, both ends of the slide groove 11 are through-arranged, and the sliders 51 can be inserted into the slide groove cavity 111 from either end of the two ends of the slide groove 11. Each of the optical auxiliary modules 5 is provided with a positioning arm 52 and a power connector 53, the head end of the positioning arm 52 is hinged to the end of the optical auxiliary module 5, and the power cord 54 connected to the power connector 53 extends from the tail end of the positioning arm 52 to the outside of the positioning arm 52, and the power connector 53 is arranged at the end of the power cord 54 outside the positioning arm 52. The end of the optical assisting module 5 hinged with the positioning arm 52 is extended in a direction away from the position of the other end thereof to the upper side of the withering trough 1, that is, the positioning arm 52 is hinged at one of the two ends of the optical assisting module 5, and the hinge slightly extends outward to allow the positioning arm 52 to flip downward.
[0027] Continue to refer Figure 2 , Figure 3 , Figure 4 , Figure 5, the above-mentioned positioning groove 12 is arranged on one side of the withering groove 1 adjacent to the position of the positioning arm 52. The positioning arm 52 is rotated around the hinge axis with the light-assisted module 5 as an axis to be embedded in the above-mentioned positioning groove 12 or leave the positioning groove 12. When the positioning arm 52 is inserted into the above-mentioned positioning groove 12, the above-mentioned power connector 53 is adjacent to the above-mentioned power socket 13 corresponding to the positioning groove 12. When the power connector 53 is inserted into the power socket 13, the length of the above-mentioned power cord 54 between the power connector 53 and the tail end of the positioning arm 52 limits the positioning arm 52 where it is located from leaving the positioning groove 12. Among them, the power connector 53 and the power socket 13 are schematically illustrated in the figure with a plug and socket structure. In actual applications, other further structures such as special interfaces, track sockets, etc. can also be used. However, as shown in the plug and socket structure in the figure, the cost of modifying the company's existing light-assisted tea withering machine is lower and the technology is more stable and durable. Relying on the structure in which the power connector 53 is combined with the positioning arm 52, the power connector 53 can be inserted into the power socket 13 only when the positioning arm 52 is inserted into the positioning slot 12, and the power connector 53 must be unplugged due to the length limitation of the power cord 54 before the positioning arm 52 leaves the positioning slot 12. This structure achieves the limitation of the charged mobile optical auxiliary module 5 at the structural level with a simpler structure, avoiding safety hazards such as pulling off the power connector 53 and breaking the wires due to the charged mobile optical auxiliary module 5.
[0028] refer to Figure 1-Figure 5 The working process of the light-assisted tea withering machine of the utility model is as follows: the number, type combination, arrangement order, arrangement interval, etc. of the light-assisted modules 5 are determined according to the needs of tea production; according to the needs, the two ends of the light-assisted modules 5 are inserted into the slide groove 11 from the through-through parts of the end of the slide groove 11, and adjusted to the position of the corresponding positioning groove 12 (wherein, 5 light-assisted modules 5 are illustrated in the figure); when the light-assisted module 5 is loaded into the slide groove 11, one end of the positioning arm 52 is assembled to the slide groove 11 on the side of the withering groove 1 adjacent to the positioning groove 12, and the withering auxiliary light source faces downward; when the light-assisted module 5 moves along the slide groove 11 to adjust its position, its positioning arm 52 is turned up along the hinge axis. Turn and lift to prevent the positioning arm 52 from being blocked by the positioning groove 12; when the light-assisted module 5 moves to the specified position, flip the positioning arm 52 downward to make it fit into the corresponding positioning groove 12, and insert the power connector 53 into the power socket 13; the tea leaves fall into the withering trough 1 from the side of the rake teeth 3 close to the head end of the withering trough 1, and are transported to the tail end of the withering trough 1 by the conveyor belt 2, and are flattened by the rake teeth 3 when passing through the rake teeth 3; when the tea leaves are transported by the conveyor belt 2, the withering fan 4 processes the tea leaves with hot air; the tea leaves are driven by the conveyor belt 2 to pass under the light-assisted module 5 in turn and are processed by the light-assisted module 5; after being transported to the tail end of the withering trough 1 by the conveyor belt 2, the tea leaves fall downward and leave the light-assisted tea withering machine.
[0029] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
