NOVELTY - A multi-layer tea baking device for improving baking effect, comprising a baking box body, the baking box body is provided with at least two annular chain plate conveyor with upper and lower set interval the upper layer chain plate and the lower layer chain plate of each annular chain plate conveyor are conveyed with tea, the cavity surrounded by each annular chain plate conveyor is provided with a heating device, the heating device comprises a plurality of graphene electric heating plates, the graphene electric heating plates are arranged at intervals along the axial direction of the annular chain plate conveyor, a heat conducting plate is set at the position 2-3 mm above each graphene electric heating plate, and the distance between the graphene electric heating plate on the same annular chain plate conveyor and the upper chain plate is less than the distance between the graphene electric heating plate and the lower chain plate. The multi-layer tea baking device of the structure has high heating efficiency, and the same heating temperature on each position of the same chain plate conveyor, ensures the uniformity of the tea baking, improves the baking effect of the tea.
