The utility model relates to a horizontal double-cylinder desolventizing machine which comprises two cylinder bodies, namely a cylinder A and a cylinder B. Rotors are arranged in the Cylinder A and the Cylinder B; a discharge port of the Cylinder A is abutted with a feed inlet of the Cylinder B by an air seal machinery II; the Cylinder A and the Cylinder B are arranged up and down; and semicircular pipe coils filled with indirect steam are wound on the outer walls of the Cylinder A and the Cylinder B to form an indirect heating body. According to the utility model, materials can be subjected to secondary desolventizing; the horizontal double-cylinder desolventizing machine is more complete in desolventizing; the up-and-down arrangement structure is compact; the space can be effectively utilized; the thickness of each cylinder body is smaller than that of an original jacket structure, so that the manufacturing cost is reduced; blades are uniformly stressed and worn in the process of pushing the materials, so that the turning mixing of the materials is strengthened and the adjustability of a rotor is improved.
