Method and device for quality control in the preparation of tablets

摘要

Quality surveillance in manufacturing tablets in a rotary tablet press involves obtaining chemical and/or mechanical data of tablets using near infrared spectroscopy (NIR) or laser fluorescence spectroscopy (LIF) sensor (36) in the compression chamber when upper rams (18) have left the dies (16) after a measuring procedure has been initiated by machine computer in response to die positions determined by a position generator relative to NIR/LIF sensor. The rotary tablet press, in a compression chamber has disposed a rotor (12) with upper and lower (20) rams, a die-plate (14), cam elements (22) for the rams, at least one compressing station, and a charging system for the powdered material. An independent claim is included for a rotary tablet press.
