Description

Technical Field

[0001] The utility model relates to a stirring device, in particular to a high-speed twin-screw twin-feeder. Background Art

[0002] A mixer, scientifically known as a blender, is a machine used to mix materials. Depending on the specific structure, the internal vertical stirring blades and external container have different shapes. The stirring of the vertical stirring blades causes the movement of the particles of the formed material to intersect, thereby mixing. Existing mixers mostly use a method where the outer wall and inner blades stir in opposite directions. However, this also means that the materials must be added all at once and the mixer must be fully stirred and shut down before they can be dumped all at once. If the mixing result is not as expected, it may be necessary to add some of the mixed materials again for re-mixing, which can result in a significant waste of time. Summary of the Invention
