The invention relates to a stacked airing box. The stacked airing box comprises a cabinet, a cabinet door and universal wheels. Annular rotary rails are separately arranged on left and right cabinet doors in the cabinet; a T-shaped rack is fixedly arranged on each of the annular rotary rails; an iron screen rack is movably arranged on the T-shaped racks; a motor is arranged on the outer side of the cabinet; a first gear is arranged on the motor; the first gear is connected to the annular rotary rail through a second gear; a vacuum pump is arranged on the top of the cabinet; a suction pipe is arranged on one side of the vacuum pump; one end of the suction pipe penetrates through the top of the cabinet and communicates to the inner part of the cabinet; an air inlet pipe is arranged on the suction pipe; a suction valve is arranged on the suction pipe; and an air inlet valve is arranged on the air inlet pipe. The stacked airing box provided by the invention has the beneficial effects thatash and impurities are prevented from being blended with sliced radix paeoniae alba; by arranging the annular rotary rails, the T-shaped racks and the iron screen racks, the radix paeoniae alba in thedrying process is uniformly irradiated; evaporated air in the cabinet is extracted by means of suction treatment, so that the drying efficiency and the drying effect are improved; the drying effect is better, the drying time is short, the labor intensity is reduced, and the cost is effectively lowered.
