Tablets Tensile strength Rotary tablet presses Single punch tablet presses Force-time profiles Tablets are solid single unit dosage forms made from dry powder blends or granules using high compression forces [1]. They are the most common drug delivery systems today: According to the International Association for Pharmaceutical Technology (APV) about 80 % of the produced dosage forms are solid [2]. Tablets offer a number of advantages: They have a high level of patient compliance. In addition, tablets are typically of excellent dosing accuracy, easy to pack, to store, and to transport [3]. A high production rate is realized on rotary presses, ...

Implementation of Microwave Sensors in Continuous Powder Feeding / A Novel Tool to Bridge Refill Phases · Meier R, Harting J, Happel J, Kleinebudde P · ¹Institute of Pharmaceutics and Biopharmaceutics, Heinrich-Heine-Universität, Düsseldorf, Germany und ²mic-GmbH, Lübeck, Germany
continuous manufacturing mass flow microwave sensor powder feeder process analytical technology Continuous powder feeding is an important unit operation to introduce material consistently into a process. Continuous granulation, continuous mixing, continuous tablet compression etc., all rely on accurate and precise feeding processes. The most common type of powder feeder works by a loss-in-weight principle. In order to obtain the desired feed-rate, the feeder is placed on a balance which constantly measures the mass of fed powder and controls the speed of the feeder. In continuously running processes, powder feeders need to be refilled frequently. During this phase, the control balance ...

Umfangreiche Tests und validierte, aber unflexible Herstellungsschritte sicherten bisher die Qualität. Unterstützt durch regulatorische Anreize sollten innovative prozessanalytische Methoden zur Überwachung in den Fokus gerückt werden. Zusammen ...
