PROCESSING POWTECH SECTION GUIDE...


SOME ISSUES CAN BE INVISIBLE. POOR FLOW RATES, FOR EXAMPLE, MAY EASILY GO UNNOTICED FOR LENGTHY periods since


they don’t result in costly downtime.


But, in the background, they will discreetly be having a negative effect on downstream systems. Obstructions, misalignments, the volume or density of the materials being processed, can all contribute, but the solutions are often as simple as replacing your feeder. When we look at plant engineering and processing components, we look at far more than mere flow control. The POWTECH world opens the door on advice which ranges from conveying and transport to storage and filling. Along the way, you’ll find hardware solutions for emptying and dosing along with an array of components such as valves, flaps, slides, compressors, coolers, pumps, reactors, recycling plants, vacuum plants and heat exchangers. Then there are the elements of measurement, control and automation, headings under which fall field-level equipment,


particle analysis, process and laboratory


instrumentation, all vital elements in the process chain. Technology is key in all aspects as is the way it is used and the way it suits a particular business. The continual monitoring and control of moisture levels, for example, enabling operators to use real-time monitoring and measuring to make immediate process adjustments. The sensors require a one-time calibration and are manufactured with a non-drift optical design to provide continuous, reliable readings with zero


Technology is every bit as much an element of good production practices as knowledge and discipline. The trick of it is knowing how best to deploy each of them


maintenance. Production efficiency improvements due to accurate real-time measurements provide both energy savings and potential increased productivity with lower material losses. Many moisture detectors use state-of- the-art components allowing installation in the most extreme locations. Or the sort of sophisticated analytical techniques that can help address issues such as caking, crusting and agglomeration in material processing. There’s rarely a one-size-fits-all solution. Bulk powders will often agglomerate during transport and storage and in most applications, the material will need to be milled before engaging downstream processes such as blending and compression, to improve its flowability. This de-agglomeration step can be time-consuming and


cause a bottleneck. Finding a solution to the de-lumping of excipients which allows a high throughput can dramatically improve system efficiency. Studies have more than once attributed specific influences to caking such as length of storage or humidity, but, thanks to powder rheometry it is now possible to measure a range of characteristics that can quantify its progression as, for example, a function of time, humidity or consolidation stress. Such insights form the sort of discussions that regularly play out among visitors and exhibitors, along with the topics of process safety, emission protection, and services such as plant construction and planning, analysis, training and education, testing establishments, laboratories and contract processing.
