The precooling drum is tempered accordingly by water. The sugar mass then flows from the drum onto the cooling conveyor - the movement is assisted by a spatula if necessary. The top of the sugar mass carpet comes into contact here with the bottom side on the cooling conveyor. In this way the sugar mass carpet is further cooled down and tempered. The sugar mass batch is joined at the end of the conveyor by using folding paddles and a kneading roller.

The temperature cools down from approx. 125º C to approx. 85ºC (for hard sugar batches). A conveyor belt feeds the cooled sugar batch from the cooling conveyor to the downstream processing machines (such as the BSK 0019 L). Operation including setting the reference values and display of the water temperatures is carried out from a central control panel.
