For gluey or depositing products, light, fine grain pourable goods and middle to high viscose pastes.
The variocleaner offers the most options for practical adjustment to product-specific and on site requirements.

The hollow screws of the Variocleaner are shaped as an isosceles triangle or isosceles trapezium. Cleaning of the processor is achieved by increasing the angular speed of one of the hollow screws to a point that its screw flights almost touch the flights of the hollow screw rotating with constant angular speed.
After the cleaning process is finished the angular speed will be reduced again.
