Abstract
A process for continuous production of partly crystalline polycondensate pellet material which comprises the step of crystallizing the pellet material in a second treatment space () under fixed bed conditions by supply of energy from the exterior by means of a process gas, wherein the process gas has a temperature (T), which is higher than the sum of the pellet temperature (T) and the temperature increase (T) which occurs due to heat of crystallization released hi the second treatment space (), i.e., (T>(T+T)). The pellets at the exit from the second treatment space () have an average temperature (T), which is 10 to 90° C. higher than the sum of the temperature of the pellets (T) and the temperature increase (T) which occurs due to heat of crystallization released in the second treatment space (), i.e., (T+T+90° C.)≥T≥(T+T+10°).
