A stirring assembly 3 is arranged inside the kneading cylinder 101. Stirring blades 102 are arranged on the inner wall of the kneading cylinder 101. The stirring blades 102 are evenly arranged at equal intervals and cover the inner wall of the kneading cylinder 101. A cross mounting frame 203 is installed on the upper surface of the kneading cylinder 101. An installation groove 204 is opened at the center of the cross mounting frame 203. The driving assembly 2 includes a second motor 205. The output end of the second motor 205 is connected with a first rotating shaft 206. A limiting convex block 207 is arranged on the outer wall of the first rotating shaft 206. The first rotating shaft 206 is clamped together with the installation groove 204 through the cooperation of the limiting convex block 207. The purpose of such setting is that after the machine starts, the first motor 202 drives the stirring spiral blades 302 installed on the second rotating shaft 301 to stir the raw materials. At the same time, driven by the second motor 205, the kneading cylinder 101 rotates in the opposite direction of the rotation direction of the second rotating shaft 301. The stirring blades 102 installed on the inner wall of the kneading cylinder 101 assist in stirring the raw materials at the same time. The stirring spiral blades 302 and the stirring blades 102 cooperate with each other to stir the raw materials more fully.

[0026] A feeding port 103 is arranged at the top of the kneading cylinder 101. A discharging port 104 is arranged at the bottom of the kneading cylinder 101.
