The invention provides a high-wind-speed auxiliary agitation drying apparatus, which comprises an apparatus body (10). The apparatus body (10) comprises a feeding device (1), an agitating device (2),a drying device (3) and a discharged material collecting device (4), wherein the agitating device (2) comprises an agitating motor (21), an output shaft (22), a driving gear (23), an overturning drum(24), a connecting device (25) and a spiral blade (26); and the drying device (3) comprises a device shell (31), a heating motor (32), heating blades (33), a heating device (34) and a wind guide plate(35). By using the apparatus, heated air can go deep into a material, and meanwhile, the overturning of the material is guaranteed, so that the heated air is in sufficient and uniform contact with the material, and then the drying effect is improved; meanwhile, the apparatus can screen the dried material preferentially and discharge the dried material from the overturning drum (24) quickly, so that the dried material is prevented from being continuously dried, and the drying efficiency is improved.
