The invention discloses a pork classification storage box. The pork classification storage box comprises a box body, a box cover, supporting legs and a storing plate, one side of the top of the box body is rotatably connected with the box cover through a hinge, a hollow cavity is formed in the outer wall of the box body, and ventilating holes penetrating through the box body are evenly formed in the inner side of the hollow cavity; and the storing plate is fixedly mounted on the side, close to the ventilating holes, of the inner wall of the box body through bolts, permeating holes are evenly formed in the surface of the storing plate, a miniature condenser is fixedly mounted on the outer sides of the supporting legs through the bolts, the output end of the miniature condenser is in threaded connection with an air guiding pipe, the end, away from the miniature condenser, of the air guiding pipe is in threaded connection with the side, close to the hollow cavity, of the box body, and theend, away from the miniature condenser, of the air guiding pipe penetrates through the hollow cavity. According to the pork classification storage box, the cold air in the hollow cavity is blown to the pork surface in a pork storage room through the ventilating holes, the storage temperature of the pork is reduced so as to prevent the pork deterioration, and the storage time of the pork is prolonged accordingly.
