摘要： The present invention relates to a process for continuous production of partly crystalline polycondensate pellet material, comprising the steps of forming a polycondensate melt into pellet material; separating the liquid cooling medium from the pellet material in a first treatment space, wherein the pellets after exit from the first treatment space exhibit a temperature TGR, and crystallizing the pellet material in a second treatment space, wherein in the second treatment space fluidized bed conditions exist, and in the second treatment space the pellets are heated by supply of energy from the exterior by means of a process gas.
