The invention relates to the technical field of material processing device, and discloses an anti-blocking material drying device. The anti-blocking material drying device comprises a case; a feedingopening and a discharging opening are formed on the case; the top end of an inner cavity of the case is fixedly connected with a heater strip; the inner cavity is rotatably connected with rollers; therollers is internally provided with heater strips; the outer surfaces of the rollers are provided with wire meshes; first flapping plates and second flapping plates are connected with the rollers; the first flapping plates and the second flapping plates are arranged on the rollers at intervals in the circumferential direction; the inner cavity of the case is fixed with multiple convex plates; elastic plates are connected between each two adjacent convex plates; the convex plates and the elastic plates are both located below the rollers; the length of the first flapping plate is greater than the length of the second flapping plate; and the first flapping plate is in clearance fit with the elastic plates. The problem of poor drying effect and blocking of the discharging opening in the drying equipment of the existing technology because material caking cannot be effectively prevented is solved.
