The present invention relates to a conical twin-screw extruder with a large length-to-diameter ratio. The temperature control device of this twin-screw extruder comprises a heating mechanism and a cooling mechanism. The conical twin-screw mechanism comprises a first screw and a second screw that meshes with each other and intersects at their axes. From the large end to the small end, the first and second screws are sequentially equipped with a feeding section, a pre-compression section, a compression section, a venting section, and a mixing section. Compared with the prior art, the present invention features an optimized screw design and higher thermal control efficiency.
