At this time, the tea pressing component 32 is reset to the initial position, and the telescopic cylinder 141 drives the tea discharge push plate 142 to move, so as to discharge the shaped and dried tea leaves. When the airflow drying device 20 is working, the heating component 23 heats the airflow component 22, and the airflow component 22 guides the airflow into the mesh cover 21. When the air is transmitted, the dry air source pipe 222 is connected to the dry air source, and the airflow first enters the flow channel plate 221 through the dry air source pipe 222. The heating component 23 heats the air flowing through the flow channel plate 221, and the hot dry air in the flow channel plate 221 enters the mesh cover 21 through the mesh holes on the side wall of the mesh cover 21 to dry the tea leaves. When the heating component 23 is working, the heating tube 233 generates heat, and the positioning plate 232 and the positioning cover box 231 are connected by a clamping structure, which facilitates the disassembly of the positioning plate 232 and the maintenance of the heating tube 233; The water-containing gas in the mesh cover 21 is discharged through the humidity measuring exhaust device 40. When exhausting, the negative pressure source pipe 42 is connected to the negative pressure source, and the water-containing gas in the mesh cover 21 is discharged after passing through the first through hole 44, the insert pipe 43, the air flow ring 41 and the negative pressure source pipe 42. During the initial drying, the first through hole 44 is used for exhaust. The controller receives the humidity data of the humidity sensor 461 and pressurizes the tea leaves and performs secondary drying when the humidity data is less than or equal to the set value. During the secondary drying, the aperture adjustment component 45 adjusts the exhaust aperture. When the aperture adjustment component 45 is working, the cylinder 452 drives the annular plate 453 and the inner sleeve 454 to descend until the second through hole 456 coincides with the first through hole 44. At this time, the water-containing gas and tea residue can be discharged through the second through hole 456, the inner sleeve 454, the drain hole 455, the airflow ring 41 and the negative pressure source pipe 42.
