Highly-efficient back-mixing roller-type aerobic composting reaction device

The invention discloses a highly-efficient back-mixing roller-type aerobic composting reaction device. The highly-efficient back-mixing roller-type aerobic composting reaction device comprises a rotating cylinder body which is connected with a driving unit capable of realizing rotation around a shaft, wherein the rotating cylinder body is horizontally inclined downwards for a certain angle along the direction from a feeding inlet to a discharging outlet; a plurality of material shoveling plates are fixedly arranged on the inner peripheral wall of the rotating cylinder body; at least two groupsof material shoveling plates are distributed along the circumferential direction of the rotating cylinder body; each group of material shoveling plates are uniformly distributed along the axial direction of the rotating cylinder body at intervals; the material shoveling plates in each group are arranged in a staggered mode; each material shoveling plate is composed of a bottom plate and a baffleplate; one ends of bottom
