The cooling roller is suitable for the efficient and continuous cooling of extrudates from approx. 3 kg/h to approx. 100 kg/h. The cooling roller picks up the product from the extruder die, distributes it over almost the entire belt width and cools the material reliably and quickly in direct metal contact. Thanks to our unique concept with the extra large wrap angle of the belt on the cooling roller, even extrudates with a very high heat capacity or particularly high throughputs can be cooled many times more efficiently and with a comparably small device. After cooling, the cooled and brittle product is broken into flakes by a conveyor and breaker screw and discharged through the outlet pipe (continuous process). The cooling roller can be controlled directly via the Three-Tec extruder's control system or can also be operated as a stand-alone device according to customer requirements.
