The stirring rack 19 provided on the reciprocating structure is used to turn the tea leaves inside the insulation box 1 through the coordinated use of the reciprocating structure and the stirring rack 19.

[0021] The reciprocating structure includes a motor 5, an eccentric rod 6, a push-pull rod 7, and a piston 8. The motor 5 is fixedly mounted on the outer wall of one side of the fixed box 2, the eccentric rod 6 is rotatably mounted on both sides of the insulation box 1 and the fixed box 2, the push-pull rod 7 is rotatably mounted on the outer wall of the eccentric rod 6, the piston 8 is slidably mounted on the inner side of the fixed box 2, and one end of the push-pull rod 7 is hinged to the bottom of the piston 8. The output shaft of the motor 5 is fixedly mounted to one end of the eccentric rod 6. When the motor 5 is started, the output shaft of the motor 5 drives the eccentric rod 6 to rotate, and the rotation of the eccentric rod 6 drives the top of the push-pull rod 7 to move with the piston 8. The piston 8 performs a reciprocating lifting motion, and in the process of descending, a negative pressure is generated above the heat preservation box 1 and the piston 8, and the air and water vapor inside the heat preservation box 1 are extracted into the interior of the fixed box 2 through the exhaust pipe 3 by the atmospheric pressure. In the process of rising, the piston 8 generates a positive pressure above the heat preservation box 1 and the piston 8, and the air and water vapor inside the fixed box 2 are discharged to the outside of the fixed box 2 through the exhaust pipe 4 by the atmospheric pressure, so that the interior of the heat preservation box 1 is in a vacuum state, and the water vapor inside the heat preservation box 1 can also be extracted to ensure the efficiency of tea drying.

[0022] There are five stirring racks 19, which are fixedly installed on the outer wall of the eccentric rod 6 at equal intervals.

[0027] Working principle: By manually twisting the push rod 12 and the sealing cover 11, the feed port 10 of the heat preservation box 1 can be opened and closed, and then the tea can be put into the heat preservation box 1, and then the manual valve is closed, and the electric heating plate 18 is started through the control panel 21. The electric heating plate 18 heats and dries the tea inside the heat preservation box 1, and then the motor 5 is started through the control panel 21. The output shaft of the motor 5 drives the eccentric rod 6 to rotate. The rotation of the eccentric rod 6 drives the top of the push-pull rod 7 and the piston 8 to perform reciprocating lifting and lowering motions. During the descent of the piston 8, a negative pressure is generated above the heat preservation box 1 and the piston 8, and the heat preservation box is lifted by the atmospheric pressure. 1, the air and water vapor inside the heat preservation box 1 are extracted into the interior of the fixed box 2 through the exhaust pipe 3, and the piston 8 generates a positive pressure above the heat preservation box 1 and the piston 8 during the upward movement, and the air and water vapor inside the fixed box 2 are discharged to the outside of the fixed box 2 through the exhaust pipe 4 by atmospheric pressure. The eccentric rod 6 drives the stirring frame 19 to rotate during the rotation process, so that the stirring frame 19 is used to stir the tea leaves inside the heat preservation box 1, driving the tea leaves to be heated evenly. After the tea leaves are dried, the sealing plate 15 is manually pushed to the right to remove the sealing plate 15 from under the discharge port 13 of the heat preservation box 1, so that the dried tea leaves can be collected.
