[0002] Tea drying is one of the key steps in the tea processing process. It can not only remove excess water from tea leaves and prevent mildew, but also help fix the shape of tea leaves, enhance the aroma and maintain the color. The tea processing high-efficiency drying equipment is a kind of equipment specially used for tea drying. It aims to improve the drying efficiency and drying quality of tea leaves to maintain the color, aroma and shape of tea leaves. It adopts advanced drying technology and intelligent control system to achieve precise control of the tea drying process, ensure that the tea leaves are evenly heated during the drying process, and evaporate water appropriately, thereby improving the quality and taste of tea leaves.

[0037] The interior of the drying bin 1 is evenly and symmetrically provided with a turning mechanism 80 for flexibly turning the tea leaves. The turning mechanism 80 includes a rotating gear 81 that is evenly and symmetrically connected to the outside of the horizontal air supply branch pipe 73. The evenly distributed rotating gears 81 rotate together through a connecting frame 82. One side of the evenly distributed rotating gears 81 is meshed with a vertical gear rod A83 at intervals, and the other side of the evenly distributed rotating gears 81 is meshed with a vertical gear rod B84 at intervals.

[0039] A mutually related linkage mechanism 120 is provided between the drying mechanism 70 and the flipping mechanism 80, and the linkage mechanism 120 includes an L-shaped connecting rod 121 that slides horizontally with the vertical air supply main pipe 72, and the vertical end of the L-shaped connecting rod 121 is fixedly connected to an abutment plate 123 that is slidably connected to the inside of the drying bin body 1 through a connecting plate 122, and a return spring A124 that is sleeved on the outside of the L-shaped connecting rod 121 is fixedly connected between the connecting plate 122 and the drying bin body 1, and an abutment inclined surface 125 is provided on the side of the abutment plate 123 away from the connecting plate 122, and the abutment inclined surface 125 is provided on the side of the abutment plate 123 away from the connecting plate 122. The outer portion of the surface 125 is provided with an abutment block 126 fixedly connected to the inner side of the sealed compartment door 6. The abutment block 126 can press the abutment plate 123 through the abutment inclined surface 125. When the sealed compartment door 6 is closed, the abutment block 126 can press the abutment inclined surface 125 to make the abutment plate 123 move downward. The abutment plate 123 drives the vertical air supply main pipe 72 to move downward through the connecting plate 122 and the L-shaped connecting rod 121 and press the return spring A124, so that the vertical air supply main pipe 72 drives the flipping mechanism 80 downward to approach the tea leaves in the drying tray 5.

[0040] The linkage mechanism 120 further includes a linkage gear 127 rotatably connected to the outside of the vertical air supply main pipe 72, and the linkage gear 127 is fixedly connected to the connecting frame 82 outside the rotating gear 81, that is, the linkage gear 127 drives the evenly distributed rotating gears 81 to rotate synchronously through the connecting frame 82;

[0041] The linkage mechanism 120 also includes a vertical sliding groove 128 symmetrically opened on the inner wall of the drying bin body 1, and a sliding plate 129 is slidably connected inside the vertical sliding groove 128. A return spring B130 is fixedly connected between the top of the sliding plate 129 and the vertical sliding groove 128. A magnetic top block B131 is fixedly connected to the bottom of the sliding plate 129, and a magnetic bottom block B132 installed inside the vertical sliding groove 128 is arranged below the magnetic top block B131. A horizontal gear rod 133 is fixedly connected to the outside of the sliding plate 129, and the saw teeth 134 at the bottom of the horizontal gear rod 133 can be turned toward After the vertical air supply main pipe 72 drives the turning mechanism 80 downward to approach the drying tray 5, the vertical air supply main pipe 72 moves toward the middle and can drive the linkage gear 127 to rotate counterclockwise through the saw teeth 134 at the bottom of the horizontal gear rod 133, so that the turning rake A85 contacts the tea leaves in the drying tray 5 and turns the subsequent tea leaves. The vertical air supply main pipe 72 moves toward the side and can drive the linkage gear 127 to rotate clockwise through the saw teeth 134 at the bottom of the horizontal gear rod 133, so that the turning rake B86 contacts the tea leaves in the drying tray 5 and turns the subsequent tea leaves.

[0042] The working principle of this embodiment is as follows: Fig. 9As shown, after the tea leaves are spread flat on the drying tray 5, the drying tray 5 is placed on the drying rack 4, so that the drying tray 5 is evenly and symmetrically placed on the drying rack 4, and then the drying rack 4 is pushed into the drying bin body 1, so that the multi-layer drying tray 5 can enter the drying bin body 1, and at the same time, the positioning blocks 9 on both sides of the drying bin body 1 can position the drying rack 4. After the multi-layer drying tray 5 enters the drying bin body 1, the air supply nozzle 74, the turning rake A 85 and the turning rake B 86 of each layer are all located above the drying tray 5 of the corresponding layer;

[0043] like Figure 4 As shown, the sealed compartment door 6 is closed, so that the abutting block 126 follows the sealed compartment door 6 to approach the drying compartment body 1, so that the abutting block 126 drives the abutting plate 123 to move downward by pressing the abutting inclined surface 125, and the abutting plate 123 drives the vertical air supply main pipe 72 to move downward through the connecting plate 122 and the L-shaped connecting rod 121 and press the return spring A124, so that the vertical air supply main pipe 72 drives the multi-layer horizontal air supply branch pipes 73 and the flipping mechanism 80 outside thereof to move downward to the drying tray 5 of the corresponding layer;

[0044] Then, the hot air blower 2, the dehumidifier 3 and the reduction motor 75 are started by controlling the display 11. The hot air blower 2 is started to supply hot air to the inside of the air supply hose 71, the vertical air supply main pipe 72 and the horizontal air supply branch pipe 73, so that the evenly distributed air supply nozzles 74 can perform hot air drying on the tea leaves inside the drying tray 5 of that layer. The dehumidifier 3 is started to discharge the moisture generated during the drying process. The reduction motor 75 is started to drive the bidirectional screw rod 76 to rotate slowly. The slowly rotating bidirectional screw rod 76 drives the vertical air supply main pipe 72 to reciprocate at a slow speed through the mobile connecting block 77, so that the multi-layer horizontal air supply branch pipe 73 drives the multi-layer air supply nozzles 74 to reciprocate to evenly dry the tea leaves laid flat on each layer of the drying tray 5.

[0045] The vertical air supply main pipe 72 drives the multi-layer air supply nozzle 74 to evenly dry the tea leaves laid flat on each layer of the drying tray 5, and drives the turning mechanism 80 of each layer to move synchronously;

[0046] When the vertical air supply main pipe 72 moves toward the middle at a slow speed, the sawtooth 134 at the bottom of the horizontal gear rod 133 can drive the linkage gear 127 to rotate counterclockwise, and the counterclockwise rotation of the linkage gear 127 drives the evenly distributed rotating gear 81 to rotate counterclockwise synchronously through the connecting frame 82, so that the vertical gear rod A83 drives the turning rake A85 to contact the tea leaves in the drying tray 5 of this layer downward, and at the same time, the vertical gear rod B84 drives the turning rake B86 to move upward away from the tea leaves in the drying tray 5 of this layer, and the position of the turning rake A85 is limited by the magnetic top block A89 and the magnetic bottom block A90 attracted to the outside of the turning rake B86, that is, the evenly distributed air supply nozzles 74 can evenly dry the tea leaves laid flat on the drying tray 5 of this layer, and can flexibly turn the tea leaves laid flat on the drying tray 5 of this layer;

[0047] When the vertical air supply main pipe 72 moves toward the edge at a slow speed, the serration 134 at the bottom of the horizontal gear rod 133 can drive the linkage gear 127 and the evenly distributed rotating gear 81 to rotate clockwise, so that the vertical gear rod A83 drives the turning rake A85 to move upward away from the tea leaves in the drying tray 5 of this layer, and at the same time, the vertical gear rod B84 drives the turning rake B86 to contact the tea leaves in the drying tray 5 of this layer downward, and the position of the turning rake B86 is limited by the magnetic top block A89 and the magnetic bottom block A90 attracted to the outside of the turning rake A85, that is, the evenly distributed air supply nozzles 74 can perform secondary uniform drying on the flat tea leaves in the drying tray 5 of this layer, and can also perform secondary flexible offset turning on the tea leaves in the drying tray 5 of this layer.

[0048] The main difference between the present embodiment and the prior art is that the present embodiment can start the reduction motor 75 to enable the vertical air supply main pipe 72 to drive the multiple layers of air supply nozzles 74 to move back and forth to evenly dry the tea leaves spread in each layer of the drying tray 5, and when the evenly distributed air supply nozzles 74 evenly dry the tea leaves spread in the drying tray 5 once, the turning rake A85 can flexibly turn the tea leaves spread in the drying tray 5 once, and while the evenly distributed air supply nozzles 74 evenly dry the tea leaves spread in the drying tray 5 for a second time, the turning rake B86 can flexibly turn the tea leaves in the drying tray 5 for a second time, that is, flexibly turn the tea leaves in the drying tray 5 for a second time, that is, evenly drying the tea leaves and turning the tea leaves evenly at the same time. The present embodiment can evenly and fully dry the tea leaves and reduce the generation of broken tea leaves.

[0049] Embodiment 2

[0050] like Figure 1-Figure 4 and Figure 8-Figure 11As shown, based on the first embodiment, a dehumidification mechanism 140 for assisting in the discharge of moisture is evenly and symmetrically arranged inside the drying bin body 1. The dehumidification mechanism 140 includes longitudinal moisture absorption pipes 141 evenly distributed on the top of the drying tray 5 and vertical dehumidification pipes 142 evenly distributed on the side of the drying rack 4. The evenly distributed longitudinal moisture absorption pipes 141 are all located at the top of each layer of the drying tray 5 and at the bottom of the upper drying tray 5. The ends of the longitudinal moisture absorption pipes 141 and the vertical dehumidification pipes 142 are both installed with a one-way valve plate 143. The longitudinal moisture absorption pipes 141 can absorb the moisture generated during the drying process of the drying tray 5 of this layer, and the vertical dehumidification pipes 142 can discharge the moisture absorbed by the longitudinal moisture absorption pipes 141 to the side of the drying rack 4 to promote the rising speed of moisture in the side space.

[0051] The ends of the evenly distributed longitudinal moisture absorption ducts 141 are fixedly connected to a Z-shaped connecting pipe 144. The end of the Z-shaped connecting pipe 144 away from the drying rack 4 is fixedly connected to a U-shaped connecting pipe 145 that passes through the drying bin body 1. A piston rod 146 fixedly connected to the vertical air supply main pipe 72 is arranged inside the end of the U-shaped connecting pipe 145 away from the Z-shaped connecting pipe 144. The outside of the U-shaped connecting pipe 145 is fixedly connected to a longitudinal connecting pipe 147 fixedly connected to the bottom end of the evenly distributed longitudinal moisture absorption duct 141. When the vertical air supply main pipe 72 moves toward the middle, it can drive the piston rod 146 to extend outward, so that the longitudinal moisture absorption duct 141 is in a negative pressure state and absorbs moisture above the drying plate 5. When the vertical air supply main pipe 72 moves toward the edge, it can drive the piston rod 146 to enter inward, so that the absorbed moisture is discharged through the vertical dehumidification duct 142.

[0052] The working principle of this embodiment is as follows: based on the first embodiment, when the vertical air supply main pipe 72 moves toward the middle at a slow speed, it can drive the piston rod 146 to extend the U-shaped connecting pipe 145 outward, so that the interiors of the U-shaped connecting pipe 145, the longitudinal connecting pipe 147 and the Z-shaped connecting pipe 144 are in a negative pressure state, so that the longitudinal moisture absorption pipe 141 absorbs moisture above the drying tray 5, so as to prevent excessive moisture from rising through the upper drying tray 5 and affecting the drying efficiency of the upper tea leaves;

[0053] When the vertical air supply main pipe 72 moves toward the edge at a slow speed, it can drive the piston rod 146 inward into the U-shaped connecting pipe 145, so that the moisture absorbed inside the U-shaped connecting pipe 145 enters the interior of the longitudinal connecting pipe 147 and is discharged through the vertical dehumidification pipe 142, so as to promote the rising speed of moisture in the side space, thereby promoting the discharge of moisture.

[0054] The main difference between this embodiment and the prior art is that: when the vertical air supply main pipe 72 of this embodiment moves back and forth to achieve uniform drying of multiple layers of tea leaves and flexible offset flipping, the longitudinal moisture absorption duct 141 and the vertical moisture discharge duct 142 can alternately absorb moisture above the drying tray 5 and promote the rising speed of moisture in the side space, thereby avoiding excessive moisture rising through the upper drying tray 5 and affecting the drying efficiency of the upper tea leaves, and at the same time can promote the upward discharge of moisture.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
