The utility model relates to an airflow-cyclone dryer. The airflow-cyclone dryer comprises a vibration feeding device, a dispersion material hitting device and an airflow drying pipe which are connected successively, wherein the dispersion material hitting device is arranged on the outer side of a pipe wall of the airflow drying pipe. The airflow-cyclone dryer is improved by adjusting the structure of the dispersion material hitting device based on the existing airflow-cyclone dryer, and therefore the problems of the quality and the safety caused by the material accumulation easily generated in the production process of the existing dryer are solved; the purposes of reducing the idling time of the production and ensuring the continuity of the production are achieved, the cost is reduced, the energy consumption and the labor intensity are reduced, and what is more, the production safety and the quality of products are guaranteed. Meanwhile, the dryer has the advantages of easy and reasonable structure, easiness in operation, convenience in check and repair, low cost and the like. The dryer can be applied to the drying process, and is especially suitable for the processes for producing and drying polyvinyl chloride.
