Cured powdery feed drying and cooling device

The invention belongs to the field of feed processing, and particularly relates to a cured powdery feed drying and cooling device which comprises a collecting box. A cooling box is fixedly connected to the top of the collecting box, a first pair of symmetrically-distributed limiting plates is fixedly connected to the top of the cooling box, first through grooves are formed in one sides of the pair of limiting plates, and fixing blocks are slidably connected into the first through grooves; a limiting piece is arranged on one side of the fixing block; the opposite sides of the pair of fixing blocks are fixedly connected with drying barrels, and the drying barrels are connected with the cooling box through fixing pieces. A convex heating plate is fixedly connected to the bottom of the drying barrel; by opening a convex heating plate and a motor, the cured powdery feed and the convex heating plate, moisture in the cured powdery feed is evaporated, the motor drives an auger barrel and an auger piece to rotate, and
