Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, and in particular, to a tea withering device. Background Technology

[0002] In the tea processing process, the first step is withering. Good withering is the prerequisite for forming high-quality tea. Withering is to make the fresh leaves lose water evenly and concentrate the cell sap. Generally, tea withering is carried out in withering troughs. Existing withering troughs are generally electrically heated, and hot air is blown into the trough by a blower to make the tea leaves in the trough lose a lot of water to achieve the purpose of withering.

[0003] In tea withering troughs, the uniformity of airflow is a key factor determining the withering effect. Uneven airflow distribution will lead to significant differences in the rate of water loss of tea leaves in different areas of the trough, affecting the consistency of the finished tea quality. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a tea withering device to achieve uniformity in the finished tea product.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A tea withering device includes a device housing, a hot air furnace, and a flow guide frame. The output port of the hot air furnace is connected to the device housing through a hot air pipe. The flow guide frame is disposed inside the device housing and is in the form of a grid. The grid of the flow guide frame forms hot flow channels, and a flow equalization plate is rotatably connected to each hot flow channel.

[0007] It also includes a driving device for driving the flow equalization plate to oscillate within the hot flow channel to adjust the gas flow direction.

[0008] Preferably, the driving device includes a driving cylinder, a rack and a gear, the gear is fixed to the shaft end of the flow equalization plate, the driving cylinder is fixed to the side of the device housing, the rack is fixed to the telescopic end of the driving cylinder, and the rack is meshed with the gear.

[0009] Preferably, the side of the device housing is provided with a plurality of support seats, which are used to support the rack.

[0010] Preferably, a guide plate is provided inside the device housing, and the guide plate is arranged along the length direction of the device housing.

[0011] Preferably, a support net is provided inside the housing of the device for placing tea leaves, and the guide frame is located between the support net and the guide plate.

[0012] Preferably, the gas discharged from the hot air duct enters above the guide plate.

[0013] Preferably, the cross-section of the guide plate is trapezoidal.

[0014] Preferably, the flow equalization plates located in the same side of the hot flow channel are connected to each other by a shaft.

[0015] This utility model has the following beneficial effects:

[0016] A hot air furnace generates heat, which is then introduced into the device housing through hot air pipes. This heats the tea leaves laid flat on the support net, causing them to wither. Furthermore, due to the upward movement of the heat flow, it flows through the heat flow channel. A drive device drives the flow equalization plate in the heat flow channel to oscillate back and forth, thereby controlling the direction of the heat flow. The oscillation ensures that the tea leaves above the heat flow channel are heated evenly, thus improving the consistency of the finished tea product.

[0030] Please refer to Figures 1 to 4 The present invention provides a tea withering device, comprising a device housing 100, a hot air furnace 200, and a flow guide 120. The output port of the hot air furnace 200 is connected to the device housing 100 through a hot air pipe 210. A support net 110 is provided inside the device housing 100 for laying tea leaves. The flow guide 120 is disposed inside the device housing 100 and is in the form of a grid. The grid of the flow guide 120 forms a hot flow channel 121, and a flow equalization plate 130 is rotatably connected in each hot flow channel 121.

[0031] It also includes a drive device 300, which is used to drive the flow equalization plate 130 to swing within the hot flow channel 121 to adjust the gas flow direction.

[0032] The hot air furnace 200 generates heat flow, which is then introduced into the device housing 100 through the hot air pipe 210. This heats the tea leaves laid flat on the support net 110, causing them to wither. Furthermore, due to the upward movement of the heat flow, it flows through the heat flow channel 121. The drive device 300 drives the flow equalization plate 130 in the heat flow channel 121 to swing back and forth, thereby controlling the direction of the heat flow. The back and forth swing ensures that the tea leaves above the heat flow channel 121 are heated evenly, thus improving the consistency of the finished tea product.

[0033] In this embodiment, combined with Figure 5 As shown, the drive device 300 includes a drive cylinder 310, a rack 320 and a gear 330. The gear 330 is fixed to the shaft end of the flow equalization plate 130, the drive cylinder 310 is fixed to the side of the device housing 100, and the rack 320 is fixed to the telescopic end of the drive cylinder 310, and the rack 320 is meshed with the gear 330.

[0034] The drive cylinder 310 drives the rack 320 to move back and forth, thereby causing the flow equalization plate 130 to swing back and forth through the meshing action of the rack 320 and the gear 330, so that the airflow is blown evenly onto the tea leaves located above the hot flow channel 121, so that the tea leaves are heated evenly.

[0035] It should be noted that the flow equalization plates 130 located in the same side of the hot flow channel 121 are connected to each other by a shaft. The interconnection between the flow equalization plates 130 allows the flow equalization plates 130 on the same side to swing synchronously by only one gear 330.

[0036] Furthermore, the side of the device housing 100 is provided with multiple support seats 340, which are used to support the rack 320. During the process of the drive cylinder 310 driving the rack 320 to move, due to its long length, the support seats 340 can ensure the stability of the rack 320 during the movement.

[0037] A guide plate 140 is provided inside the device housing 100, and the guide plate 140 is arranged along the length direction of the device housing 100. Because the device housing 100 is relatively long, and the hot air duct 210 is usually located at the center of the device housing 100, the heat flow, after entering the device housing 100, diffuses less towards the edges inside the device housing 100, resulting in uneven heating of the tea leaves at the upper edge of the support mesh 110. Therefore, in this embodiment, by providing the guide plate 140 with a trapezoidal cross-section, the gas discharged from the hot air duct 210 enters above the guide plate 140. This allows the heat flow to move towards the sides through the inclined portion of the guide plate 140, making the heat flow rise more evenly.

[0038] It should be noted that the flow guide 120 is located between the support net 110 and the flow guide plate 140.

[0039] The heat flow is guided by the guide plate 140 so that it can diffuse to the inner edge of the device housing 100. At the same time, the heat flow is evenly applied to the tea leaves on the surface of the support net 110 by the swinging action of the guide frame 120 and the flow equalization plate 130.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
