The invention discloses an intellectualized microwave continuous drier and a control method thereof; the drier comprises a rack, a conveying belt, a conveying belt wheel, a driving motor, an instrument control box and a computer; two ends of the conveying belt are respectively provided with a feed hopper and a discharge hopper and the conveying belt runs through a plurality of microwave drying cavities with doors; each microwave drying cavity is internally provided with a microwave magnetron, a temperature sensor, a humidity sensor and a speed-regulating fan; the feed hopper and the discharge hopper are respectively provided with a moisture sensor, and the conveying belt is driven by a speed-regulating motor controlled by a frequency converter. A control system can automatically draw variation curves of the temperature and the humidity of the materials in each drying cavity and the water content ratio of the discharged materials in the drying process of the materials in shorter time according to the collected data of the temperature, the humidity and the water content ratio of the materials in the drying process of the materials, can optimize control parameters continuously according to the change of the temperature, the humidity and the water content ratio in the drying process of the materials, and can regulate the system parameters automatically and realize the dynamic optimization of the drying technique parameters.
