This is carried out using a scraper which is positioned at the end of the steel belt cooler (steel belt deflection/drive drum) under a certain angle to the steel belt and which is pushed onto the steel belt using two pneumatic cylinders.

A third cylinder generates the movement of the scraper. This movement prevents small, hard product particles from settling between the scraper edge and the steel belt, thereby preventing damage to the steel belt in the form of scratches and grooves.
