This utility model relates to the field of drying equipment and provides a hot air drying device for dehydrated vegetables. It includes an outer cylinder and an inner cylinder installed inside the outer cylinder, both with openings at the top. The bottom and sides of the outer cylinder have air inlets and outlets, respectively. A fan structure is installed at the bottom of the inner cylinder. A circulation chamber is provided between the outer and inner cylinders. A first heating grid is located between the inner bottom of the outer cylinder and the inner cylinder, and a second heating grid is located between the inner top of the outer cylinder and the inner cylinder. The top of the outer cylinder has a removable cover, and the bottom of the cover has several trays at different heights. This device effectively solves the problem of uneven hot air distribution in existing drying equipment. The synergistic effect of the inner and outer cylinders ensures that the hot air is evenly distributed within the inner cylinder, avoiding over-drying and scorching of vegetables due to excessively high local temperatures. This not only significantly improves the quality of the dehydrated vegetables but also greatly shortens the drying time and increases drying efficiency.
