Working principle of vertical stirring dryer

The vertical mixing dryer is mainly used for mixing plastic particles of various colors. The dryer is one of the necessary supporting equipment for injection molding machine and granulator. Plastic particles enter from the feed hopper and slide upward along the blade surface under the action of the propelling force of the spiral blade. Under the action of the centrifugal force of the upper part, they disperse around the barrel, and the scattered materials move downward continuously, The circulating outlet and the circulating outlet in the barrel are continuously driven and lifted by the spiral blades. This cycle is repeated to achieve the purpose of mixing. At the same time, the air is sent to the electric heating box by the blower. After heating, it becomes hot air, which is automatically controlled by the temperature control meter. The uniform and suitable hot air penetrates through the resin, passes through the material layer, and carries out heat alternation to continuously take away the moisture. The resin particles are continuously purged and dried from top to bottom during the descending process, completing the high-efficiency drying and mixing process.
