applications Innovative design & attention to detail deliver a compact, flexible and efficient Tea Blending Plant Leading industrial process and mixing specialists JR Boone Ltd have designed, installed and commissioned a comprehensive tea blending and mechanical handling system for a leading UK specialist tea manufacturer. Finlay’s has installed equipment from John R Boone to improve production flexibility and increase capacity at its highly automated teamaking factory in West Yorkshire. It replaces a cone blender that had a capacity of only 250kg of tea leaves and was labour intensive to charge, operate and clean. John R Boone supplied a new 1500 litre drum blender, spray system for the flavoured oils and computer control that fully integrates with the on-site materials handling system. Tea is moved through the factory in hundreds of standard tote bins, and electronic tags or badges are used to keep track of them all. Space was at a premium, and despite having a capacity that would potentially increase batch size significantly, Boone designed a blender that fits into the same space as the previous equipment. This also means the original elevator and some of the feeders could be retained. Finlay’s and John R Boone engineers, together with senior tea buyer and blender extensive trials were conducted prior to purchase, to ensure the blender met all quality standards while delivering process benefits. JR Boone’s MD Chris Boone says the Client is very pleased with the finished plant and he concludes: “The whole plant was installed and commissioned by our engineers on time and within budget. Bringing product to and from mixers and blenders can be as important as the mixing process itself and requires in depth understanding of the of product behaviour in each part of the process. By taking full responsibility for the complete system our engineers working in close co-operation with the Clients team delivers optimised control of the mix process, whilst ensuring the highest product integrity is maintained.” For more information contact J R Boone Ltd, Congleton, Cheshire.

Developed by IDS and known as reactive pump control, the new method of controlling sludge in sewage treatment plants uses an ABB low voltage AC drive, combined with a specially written software algorithm to measure viscosity and achieve the flow control demanded by the sludge pumps. The system was trialled at Severn Trent’s sewage treatment site at Pye Bridge. It reduced pumping time by 90 percent by running the pump on average for 10 minutes per five hours, saving £42,000 a year. A number of other installations are now operational at Rainworth, Boughton, and Calverton. Overall, savings in energy and maintenance hours across the sites have totalled £100,000 a year.
