After the homogeneous mixing in of steam in a conditioner the product remains, during a preset length of time, in this heated and insulated Retention Rime Barrel (RTB). After the retention time barrel the product can be further treated in a pellet mill, extruder or meal cooler. The thermal treatment of the product results in an easier operation of the pellet mill, which simultaneously results in an improved pellet quality.
