[0032] The heat treatment mechanism 2 performs a pre-treatment of the tea leaves for withering, that is, destroying the enzyme activity in the tea leaves by heating to prevent the tea leaves from oxidizing and deteriorating; wherein, the support plate 201 is used for the installation of the heat treatment mechanism 2 and the support mechanism 1, and the heating tank 202 serves as the operating body of the heat treatment mechanism 2, so that the tea raw materials are heated more evenly, which helps to maintain the quality of the tea leaves; the electric opening and closing system 203 is used to adjust the air inlet and outlet volume of the tank body 202a, and is also used to assist in adjusting the internal temperature of the tank body 202a to meet the withering requirements of different types of tea, and is also used to control the feeding and unloading of the tank body 202a.

[0033] Specifically, the electric opening and closing system 203 includes a bidirectional electric push rod 203a fixed inside the positioning frame 202b, a swing arm 203b movably connected to the telescopic end of the bidirectional electric push rod 203a, a connecting rod 203c movably connected to the other end of the swing arm 203b, a bending arm 203d movably connected to the end of the connecting rod 203c, and a sealing chamber cover 203e movably arranged at the end of the bending arm 203d.

[0035] The feed bin 202d, exhaust bin 202g, air intake bin 202f and discharge bin 202e are all matched with the bin opening opened at the end of the tank body 202a, and the feed bin 202d, exhaust bin 202g, air intake bin 202f and discharge bin 202e are all inclined shell structures.

[0036] The operation process of this embodiment is as follows:

[0037] 1. Open the sealed compartment cover 203e inside the feed bin 202d, put the tea leaves to be processed into the tank body 202a through the feed bin 202d, and then close the sealed compartment cover 203e inside the feed bin 202d;

[0038] 2. Open the exhaust bin 202g and the air inlet bin 202f, input hot air or steam from the air inlet bin 202f, and the input hot air or steam is transported and moved along the tank body 202a, passing through the tea raw materials built into the tank body 202a in sequence, and discharged from the exhaust bin 202g after completing the heating treatment. It should be noted that a partition structure should be set at the bin opening corresponding to the air inlet bin 202f to prevent the tea raw materials from falling.

[0039] 3. After heating is completed, open the discharge bin 202e and discharge the processed tea leaves.

[0040] In the above steps, the opening and closing of the sealing chamber cover 203e are all achieved through the electric opening and closing system 203.
