Patent abstract
A method of crystallizing polymeric pellets includes a step in which a plurality of polymeric pellets are introduced into a crystallizer. While within the crystallizer, the plurality of pellets is contacted with a plurality of solid additives for the purpose of adjusting the average pellet temperature. The plurality of solid additives adjusts the temperature of the pellets by having a temperature sufficient to allow at least partial crystallization of the plurality of polymeric pellets while maintaining the average pellet temperature below the melting temperature. Finally, the plurality of polymer pellets is removed from the outlet of the crystallizer.
