The utility model relates to a high-efficiency twin-screw extruder for plastic granules, comprising a bottom plate. The top of the bottom plate is fixedly connected with an extruder body, the top of the extruder body is communicated with and fixed with a feeding valve, the top of the feeding valve is communicated with and fixed with a feeding pipe, a serpentine pipe is fixedly sleeved on the outer side of the feeding pipe, a connecting box for storing water is arranged above the extruder body, the connecting box is communicated with both ends of the serpentine pipe, and an extrusion driving device for squeezing water from the connecting box into the serpentine pipe is arranged on the extruder body. In the utility model, cold water is added into the connecting box, and the cold water is discharged into the serpentine pipe through the extrusion driving device. The serpentine pipe absorbs heat on the feeding pipe, and the cold water absorbing heat is discharged into the connecting box, so that the feeding pipe can be cooled, the plastic granule raw materials in the feeding pipe are prevented from being in a colloidal state after being heated due to heat absorption of the feeding pipe, the feeding pipe is not blocked, and the production efficiency of the twin-screw extruder for plastic granules is improved.
