Extrusion International 3-2017

31 Extrusion International 3/2017 „This twin screw extruder is the smallest machine Leistritz has ever built,“ says Albrecht Huber, Head of Pharma Extrusion at German Leistritz Extrusionstechnik GmbH. “We will be presenting the concept of our small- est extruder which is applied in the pharmaceutical in- dustry.“ On each of the seven fair days, there will also be an Info Hour at 5 pm giving an “Insight into Extrusion Technology 4.0”. „Our aim is to provide our customers an added value. This definitely includes some of the fea- tures dealing with Industry 4.0. We will show that in our lectures with a few examples,” says Huber. Those exam- ples involve efficient service via iGlasses, the advantages of an online rheometer used in both R&D and produc- tion. In addition, visitors will see how the process can be analyzed by means of UV light. ZSE 12 HP-PH The ZSE 12 HP-PH realizes a throughput of 50 to 1,000 g/h and is therefore ideal for research and development. The production of clinical batches is also possible with this machine, depending on the requirements. During the design phase of the ZSE 12 HP-PH special attention was given to easy handling, simple assembly and disas- sembly, as well as good cleanability. The machine has a mobile design and horizontally split barrels which facili- tate a look at the process. The screws are only available in compact layout in order to reach maximum torques. „The heating/cooling system was a very important issue for us,“ says Albrecht Huber. “We invented an innova- tive concept which has not been available in the phar- maceutical market until now.” It facilitates the control of eight separate heating and cooling zones, and it also has temperature probes. The heating/cooling device can easily be assembled and disassembled due to a simple clamping system. “A further highlight is the power- ful drive,” explains Albrecht Huber. The high torque of 20 Nm ensures stable operation at various process condi- tions and scale-up to the larger next machine size. After all, the geometrical characteristics of the ZSE 12 HP-PH comply with the larger ZSE HP-PH machines. All this is rounded off by a PLC control with a large touch screen that controls and monitors all necessary extruder func- tions like torque setting and heating/cooling.
