The utility model discloses a grain dryer, which comprises a material box and a heat transfer box, wherein a halftone is paved in the material box and divides the material box into an upper-layer space and a lower-layer space; a furnace chamber, a heat conducting tube and at least one fan are arranged in the heat transfer box; the furnace chamber is positioned at the bottom of the heat transfer box; the lower end of the heat conducting tube is communicated with the furnace chamber, and the upper end extends out of the heat transfer box; the fan is arranged above the furnace chamber and the heat conducting tube, and blows air downwards; the top of the heat transfer box is communicated with the top of the material box; the bottom of the heat transfer box is communicated with the bottom of the material box. By forming hot air circulation, the grain dryer saves energy and reduces emission, materials to be dried are not required to be turned, hot air penetrates through the material from bottom to top, and all mate
