The utility model discloses a rotary spiry dryer which comprises a seat, a loop, and a dryer cylinder. The loop is fixed on the seat; the dryer cylinder is positioned on the loop; the inner wall of the dryer cylinder is provided with a spiry feeding plate along the axial direction of the dryer cylinder; a hot wind pipe is arranged inside the dryer cylinder; small air inlet holes are arranged on the hot wind pipe of the dryer cylinder. The utility model has the advantages of simpler structure, a good drying effect, and is not easy to damage the particle materials to be dried. While in work, the feeding materials move toward the rear of the dryer cylinder along the axial direction of the dryer cylinder under the push of the spiry feeding plate. In movement, the feeding materials make an exchange with the hot wind blowing from the small air outlet holes of the hot wind pipe. When the feeding materials move toward the rear of the dryer cylinder under the push of the spiry feeding plate, the feeding materials which have been dried will be sent out through a material delivery groove, and thereby the whole drying process of the feeding materials is realized.
