The utility model relates to a bismuth product dryer which comprises a drying chamber, the sealed door of the drying chamber, a guide rail, an exhaust opening, a heat insulation layer, an inspection hole, baking electric furnace heating wires, and the like. The surroundings, the top part and the bottom part of the drying chamber are lined by the heat insulating layer; an arc-shaped convex roof which is lower in the inside and higher in the outside is formed on the top part; meanwhile, the top part is provided with the exhaust opening, which is convenient for vapor to escape out; the baking electric furnace heating wires are reasonably arranged on the walls at the surroundings and the top part to implement heat radiation on a water draining tray and a bismuth needle on a desk-type baking vehicle arranged at the center of the drying chamber by different angles, and the baking temperature in the drying chamber is controlled between 86 DEG C and 106 DEG C and the baking time is controlled between 40 minutes and 45 minutes; meanwhile, the inner wall is provided with temperature measuring holes so as to monitor the drying temperature in real time. The bismuth product dryer can reasonably control the baking temperature, reduce the humidity, prevent the bismuth needle from being oxidized, and guarantee the quality of the bismuth needle products.
