Counter-Rotating Twin Screw Extruder

Counter-Rotating Twin Screw Extruder

A revolutionary extrusion system designed to meet your food formulation's toughest challenges.

The ContraTwin is designed with twin-screw extrusion features but with re-engineered screw designs and rotation direction to accommodate future feed formulation. Developed to convey very sticky and puffy material (such as high fiber materials like plant protein), ContraTwin uses a very positive pump that does not waste mechanical energy or shear. For tougher materials, operators can perform cooking in the mid-barrel system. The result of this strong pump and cooking significantly increases efficiency and utilizes low Specific Mechanical Energy (SME) when compared with other single or co-rotating twin-screw extrusions.

Key Features

  • Patented counter-rotating twin screws rotating system
  • Controlled and full utilization of the specific mechanical energy (SME) and specific thermal energy (STE), allowing precise control of the extrusion process
  • Gentle handling for maximum product quality
