Design with flexibility
Extruder for wet and hot melt extrusion processes
Coperion has launched a completely flexible continuous pharma extrusion system suitable for research and development, as well as for small-scale production. This ZSK 18 Megalab extruder fulfills the requirements for both wet extrusion and hot melt extrusion (HME) processes. The first of these ZSK 18 MEGAlab 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. It offers higher efficiency and uniformity than batch processes.
Besides the extruder the system comprises two Coperion K-Tron gravimetric loss-in-weight feeders with superior accuracy in API and liquid feeding, a cooling belt, and a Coperion Pelletizing Technology strand pelletizer.
Extrusion system offers process flexibility
With a throughput rate of 10 kg/h, the ZSK 18 Megalab is suitable for both wet extrusion and hot melt extrusion (HME) on a laboratory scale. 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 has 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 (Process Analytical Technology) sensors.
The Coperion K-Tron liquid gravimetric loss-in-weight feeder fulfills Atex requirements and can be connected to each of the barrels of the extruder process section. This flexibility in feeding also applies to the Coperion K-Tron API gravimetric loss-in-weight feeder. It can be mounted on the first barrel or fourth barrel of the process section. This allows the use of the ZSK extruder for processes requiring process lengths of 32 L/D as well as of 20 L/D.
The Coperion K-Tron gravimetric feeders also offer flexibility in their ability to handle a wide variety of materials, with even difficult flow characteristics and variable feed rates. This flexibility, coupled with Coperion K-Tron’s superior digital weighing and controls technology, ensures high accuracies in materials feeding, all critical to the continuous pharmaceutical process.
The ZSK extruder itself and all peripheral equipment are very compact in size and are movable on wheels for optimum usage in laboratory conditions. The GAMP control system, as well as the water cooling manifold, is integrated into the stainless steel base frame of the ZSK extruder. Thanks to plug & play connections commissioning is possible in the shortest times.
Independent lines of feeders
Control and monitoring options for dispensers
Coperion K-Tron has added new features to its proven K-Vision software. The K-Vision controller is a graphical operator interface for controlling multiple devices such as feeders or feeder refill (vacuum receivers) in a process. With the release of K-Vision Software version 2.0, the K-Vision is now able to handle a total of 24 devices (e.g. KCM feeder controls or MPC refill controls) in one or two lines. This is a major upgrade over the previous version which managed a maximum of 16 feeder controllers in a single line. K-Vision uses a 12.1-inch color LCD display together with a touchscreen as the primary operator input mechanism. It offers a quad screen display mode for viewing multiple pages on one feeder or a single page on multiple feeders. Support for over a dozen languages – including Chinese and Japanese – is included, and additional languages can be added on request.
Maximizing product quality while minimizing the need for direct supervision
Designed for simple operation and fast and easy start-up, K-Vision offers graphic visualization of process information, utilizing flexible, easy to use trend graphs. This feeder interface offers event logging and supports all of the different feeding control types for both continuous and batch operation. Easy to maintain, K-Vision software updates are possible by updating files on a compact flash card or by using a USB flash drive.
K-Vision offers a variety of remote access options. A second K-Vision can be connected via Ethernet as a remote interface for visualization and control of feeder and line parameters. K-Vision also comes with a VNC server, allowing any VNC client – on a PC, tablet or smartphone – connected to the same network to be used as a secondary user interface. In addition to the current connectivity options, including VNC, Ethernet/IP, Profinet, Modbus TCP as well as others, K-Vision now also has email capability. No optional hardware or software is necessary – it is a standard feature. The K-Vision HMI can easily be set up to email a notification to one or more persons when key events occur, such as: the compounding line stopped, the compounding line started, a feeder is running out of product, a pneumatic receiver is not receiving pellets, notification of a specific alarm, etc. K-Vision can also be programmed to send log files by e-mail, such as feeder event logs, parameter changes, alarm logs, etc.
