The invention discloses a solar drying machine special for marine product deep processing. The machine is characterized by comprising a shell, multiple sets of sliding rails, multiple inserting-in openings, a door, a solar cell panel, a storage cell, multiple drying plates, multiple sockets, an electronic type temperature controller and wheels. A drying cavity is formed in the shell, the sliding rails are evenly spaced and horizontally embedded on the cross section in the shell, the inserting-in openings and the sliding rails are formed in the side wall of the shell in a one-to-one correspondence penetrating manner, the door is buckled on the inserting-in openings in the side wall of the shell in an opening and closing manner, the solar cell panel is laid on the side wall of the shell, thestorage cell is electrically connected with the solar cell panel, the drying plates are detachably inserted in the shell, the sockets are arranged on the inner side wall of the shell, the sockets arein one-to-one correspondence to plugs inserted in the drying plates from the inserting-in openings, and the sockets are electrically connected with the storage cell. The wheels are arranged at the bottom of the shell. Solar energy can be applied to carry out temperature controllable drying on various materials, the size is small, the structure is simple, and use is convenient and safe.
