The invention discloses an intelligent drying and cooling device for firework and firecracker powder. The intelligent drying and cooling device comprises a drying box, an intelligent hot-air blower, an electronic-control dehumidification valve and a PLC, and a temperature sensor, a humidity sensor and an ultraviolet light tube are arranged in a box body of the drying box. The PLC controls the airsupply quantity of the intelligent hot-air blower, the staged drying mode is adopted, the air supply temperature and the air supply quantity of the intelligent hot-air blower are increased at the early drying stage and decreased at the later drying period, and finally, the intelligent hot-air blower is controlled to supply cool air to cool the powder. According to the intelligent drying and cooling device for the firework and firecracker powder, the temperature and the humidity in the drying box are automatically controlled through the PLC, different air supply quantities are set at the different drying stages, the dr
