<p>Material, for example food material, is extruded through an extrusion die and cut into individual portions by a cutter blade which reciprocates across the die. A hot air blower device directs hot air against the cutter blade to prevent the food material, e.g., pretzel dough, from adhering to or accumulating on the cutter blade, thereby reducing machine down time caused by the need to periodically stop and clean the cutter blade. The hot air blower device receives cool air which is passed through the hot air tools and expelled as hot air by a fan-shaped nozzle disposed opposite the cutter blade. <IMAGE></p> |
