Coperion launched a flexible continuous pharma extrusion system suitable for research and development, as well as for small-scale production. With a maximum throughput rate of 10 kg/h the ZSK 18 Megalab extruder fulfills the requirements for both wet extrusion and hot melt extrusion processes. For wet extrusion processes the system comprises more than ten different die plates with various numbers of die holes and die hole diameters. For hot melt extrusion applications Coperion equipped the ZSK extruder with a die head that has several exchangeable nozzles to provide different strand diameters. The die head offers additional bore holes for PAT sensors. The first of these extrusion systems with an 18 mm screw diameter has recently been delivered to a major international pharmaceutical company and is in use for a variety of different continuous process tasks. Besides the extruder the system comprises two Coperion K-Tron gravimetric loss-in-weight feeders with high accuracy in API and liquid feeding, a cooling belt, and a strand pelletiser. The gravimetric loss-in-weight feeder fulfills Atex requirements and can be connected to each of the barrels of the extruder process section.
