摘要： A self-cleaning extruding apparatus with two co-rotating screws and the method thereof are provided here. Said apparatus is comprised of a screw mechanism, a barrel (1), a feeding port (10), a venting port (11), and a discharge port (12). Said screw mechanism is comprised of the first screw with one tip (3) and the second screw with two tips (4). There is a baffle in the channel of the first screw and the baffle's height is lower than that of the screw flight. The baffle will cause hyperbolic perturbation in the shape of a 'figure 8' flow pattern above the top of the baffle. The first and second screws rotate at the same speed and touch each other at all times, thereby achieving a self-cleaning function. The baffle will generate chaotic mixing in the screw channel caused by the hyperbolic perturbation. Topological chaos is also introduced into the screw channel by the mechanism 'one part divided into two parts, then two parts converging into one part, and then one part divided into two parts once more'. Each of the screws in the present invention uses an asymmetrical flow channel geometrical shape, such that a periodic action like 'compression-expansion-further compression-expansion further' works. The above three enhancement mechanisms work together to efficiently accelerate melting and mixing.
