The utility model provides a parallel-flow particle and powder material cooler. The parallel-flow particle and powder material cooler comprises a rack, wherein a cylindrical cylinder body is arranged on the rack and is connected with the rack through rolling rings fixedly arranged at the both ends of the rack through the periphery of the cylinder body; a super material board is welded with an inner ring of the cylinder body; a tooth ring around the cylinder body for one circle is arranged on a middle section of the cylinder body; the tooth ring is engaged with a gear motor fixedly arranged on the rack; a hole is formed in the center of the plane at the front end of the cylinder body, and is connected with an air blower; the air blower is fixedly arranged through the rack; a feeding opening is arranged at the upper part of the plane of the front end of the cylinder body; a blanking cabin is connected with the back end of the cylinder body; an inverted cone-shaped upper cover shell is covered at the upper part of the blanking cabin; a hole is formed in the middle part of the upper cover shell, and is connected with a U-shaped pipeline; a catcher is connected with the other end of the U-shaped pipeline. The parallel-flow particle and powder material cooler adopts a parallel-flow manner, so that the service life of the air blower is prolonged and the production efficiency is improved simultaneously; with the adoption of connection of a rolling ring and transmission of the tooth ring of the gear, the rotation stability of the cylinder body is improved, and the production cost is reduced.
