Industrial rotary tablet
Industrial rotary tablet presses International representatives of almost all user segments gathered at Powtech, when 825 exhibitors from 35 countries showcased their innovations and best practices in six halls. The high quality of the event was not just reflected in the exhibitors but also in the first-class programme of the Partec Congress and the exhibitor presentations in the exhibition halls. “In its scope and diversity, the pairing of Powtech and Partec makes for an event that is not to be missed by industry representatives,” stressed Beate Fischer, Director of Powtech and Partec. One highlight of the Partec Congress was the presentation of the Friedrich Löffler Prize by the VDI-GVC during the official opening of Partec. This award recognises young experts from industry or the research community who have demonstrated particular merit in the fields of particle research, particle technology and product design. Jun. Prof. Dr.-Ing. Carsten Schilde from the Institute for Particle Technology at the TU Braunschweig received the award for his outstanding engineering achievements and knowledge in the field of particle characterisation and modification. Picture: GEA Range of dispersion equipment Particle measurement without dispersion does not work. Therefore Parsum offers a wide range of dispersion equipment for their inline probes – the IPPseries. These small accessories, mounted directly on the probes, are being operated with compressed air and dilute and sepa - rate various particle streams with different properties. There are dispersers with low shearing forces ensuring a sensitive treatment of the granules, while particles below 100 μm can be dispersed with high shearing forces, such as found in milling processes. Thus, sticky, wet and most adhesive particles can be separated as needed. As well as GEA’s R-series rotary tablet presses allow for short cleaning and format changeover times and the tool-free disassembly and reassembly of all removable parts. The R55 is a versatile industrial rotary press for a wide range of powder product processing applications. It can be supplied with a number of optional features to improve and expedite the tablet production process and provide higher lev - els of control. The hold-up/ hold-down system, in combination with an optimised die design, prevents tablet lamination or capping, and features such as die wall and punch face lubrication are designed to optimise tablet ejection. In addition, proprietary punch holders with bearings rolling on cams mean that ejection forces up to 10 kN can be tolerated. Steel, carbide and ceramic compression tools can be supplied as standard, but the customer is free to use a third-party source. GEA will provide the necessary tool drawings with the press. www.cpp-net.com Online search: cpp0219gea for dispersion in liquids and the extraction of dispersed partial currents, there are suitable so - lutions available. This means that the growth of particles in fluidised beds or high shear processes can be tracked in real time. A moisture content of 20 % and more does not interfere the measurement. Even if layers of powder settle on the surface and the windows of the processing chamber, the optics of the probe remain free, due to an elaborate beam design. In continuous processes this enables cleaning intervals of up to several weeks and months. www.cpp-net.com Online search: cpp0219parsum Picture: Mareike Bähnisch Picture: Parsum 40 cpp 02-2019
Smart vacuum conveying Picture: Piab As it becomes ever important to ensure the ingredients are conveyed in a controlled manner to dosing and mixing equipment, the autotuning feature of Piab’s Piflow Smart vacuum conveyor automises the process of powder and bulk conveying. Based on its renowned Coax ejector technology, the Piflow Smart is pre-programmed with advanced algorithms to elimi - nate complex manual timer settings and allows continuous adaptive automatic fine tuning of the conveying process as well as recipe handling. Equipped with advanced sensor technology, it optimises and increases throughput up to 50 % higher compared to conventional conveyor systems. Smart electrical control data collection and analysis for overall process optimisation, and real-time adjustment become part of the daily routine. Moreover the Piflow Smart vacuum conveyor is equipped with further elements that allow easier and safer product handling. These are among others, automatic filter cleaning, multiple filter shock, material safety blockage function and antistatic filters and seals upon request. For usage in the pharmaceutical and food industries all materials in contact with the conveyed product fulfil the requirements of FDA and EC No. 1935/2004 and are designed according to USDA guidelines. www.cpp-net.com Online search: cpp0219piab Modular vacuum processing plants The modular vacuum processing plants Zoatec BG structured in assembly groups can be used when dry powders and liquids, or liquids and liquids, have to be mixed, dispersed and emulsified. As a result, they cover a wide product spectrum for liquid to semi-solid applications in the food industries. In addition, they are characterised by short batch times. The complete processing plants from AZO Liquids are assembled from Picture: AZO standardised modules. The modules are independent from the process parameters, and can be adapted to the requirements. The entire series is designed according to similar geometrical principles, thereby making scale-up considerations much more precise. As a result, it is possible to concentrate on the actual process parameters in the planning phase, in order to make realistic predictions. Furthermore, the design offers advantages in the areas of production, cleaning and maintenance. The vacuum processing plants range from 10 l pilot plants through to 12,000 l production plants; and from 100 up to 5000 l/h in the case of plants for continuous production processes. www.cpp-net.com Online search: cpp0219azo cpp 02-2019 41
