Under the drive of the axial fan, the hot air circulates in the oven to transfer the heat with the material on the baking tray to take away the moisture of the material. The humid air that reaches a certain temperature is discharged from the humidity outlet, and the fresh air enters the oven through the air inlet to supplement it, maintaining the temperature and relative humidity set in the oven to achieve the purpose of baking.
