Abstract: A maturation device for uncured polymeric dosage forms includes an external drum with an upstream inlet for entrance of a fluid with uncured dosage forms, and a downstream outlet for discharging cured dosage forms. The maturation device further includes a first body inside the drum defining at least one maturation chamber extending in the body between an upstream chamber inlet, in fluid communication with the inlet for uncured dosage forms, and a chamber downstream outlet. A first separation element is also included having a solid region, and a passing-through region, able, in an open condition of the chamber downstream outlet, to open the chamber outlet. At least the internal body is rotatable around an own axis to determine the closing/opening condition of a chamber downstream outlet of the internal body.
