The existing steam dryer includes an upper belt inlet and outlet and an inlet and outlet, with a screen inside, a heating chamber above the screen, and a shell of the hot air chamber below the screen, so that the tea leaves can be fed automatically. After the inlet enters the heating bin above the screen, the hot air is sent from the air inlet into the hot air bin below the screen, and the hot air passes through the screen to dry the tea leaves on it and is discharged from the air outlet on the top of the bin. The air outlet on the top of the silo is equipped with an exhaust fan, which exhausts air quickly. In addition to certain moisture and dust, the discharged air also has a high temperature. Therefore, such direct discharge will inevitably waste heat energy resources, which is not conducive to tea enterprises. The energy saving and consumption reduction will affect the economic benefits of tea enterprises. Therefore it is necessary to improve the prior art.
