  • Patent number: 12134210
    Abstract: A method and an apparatus for rapid and efficient heating of polymer pellets in preparation for processing in a plastifier. For introduction of heat energy, a gas, preferably dried air, is introduced into the polymer pellets flow so as not to be in direct countercurrent thereto. The gas is preferably introduced in its still hottest state in a targeted fashion, for the purpose of rapid energy input, at a freely selectable location. This preferably takes place at the material output of the booster hopper. The gas is preferably conducted by way of cascades, which can be of a variable design, and flows through the bulk material at least twice. The speed of the flow can be influenced.
