This is carried out using a scraper which is positioned at the end of the steel belt cooler (steel belt deflection/ drive drum) at a defined angle to the steel belt. A pair of pneumatic cylinders push the scraper against the steel belt.

A third cylinder controls horizontal oscillation of the scraper. This prevents small, hard product particles from settling between the scraper edge and the steel belt, eliminating risk of damage to the steel belt in the form of scratches and grooves.


  • Pneumatically actuated
  • Equal contact pressure
  • Smooth discharge
