One of the problems faced with blowing-seal type rotary valves is to maintain the air velocity between the valve and the conveying pipe while still achieving a good rotor pocket purge. Designers at this company have solved this problem using computational fluid dynamics (CFD) software, in conjunction with a standard CAD package to determine the profile that would guarantee minimum pressure loss and maximum pocket purge. One of these CFD-designed profiles was chosen (photo) for the comany’s new modular valve range. There is hardly any drop in air velocity during conveying with the smoother airflow through the valve, which results in improved rotor life and efficient pocket purging. This in turn leads to increased valve life, because high velocity-wear erosion is reduced by the fuller, smoother airflow. — Rota Val Ltd., Chippenham, Wiltshire, U.K. www.rotaval.co.uk

The expanded HydroWhirl Poseidon line of tank-washing nozzles now includes lower flowrates. The nozzles can now handle flowrates ranging from 4.45 to 26.3 gal/min. The smaller-sized nozzles are designed to fit through openings as small as 2 in., while maintaining a slow and controlled rotation speed. Complete 360-deg omnidirectional coverage allows for increased cleaning efficiency, and the nozzles’ slow-spinning spray and longer spray dwell time on the target surface increase impact when compared to conventional rotating designs. Fluid-driven and lubricated, these rotating tank-cleaning nozzles are constructed of corrosion-resistant polytetrafluoroethylene (PTFE) material and are ideal for harsh chemical environments. — BETE Fog Nozzle, Inc., Greenfield, Mass. www.bete.com

This modular “pod” system is a self-contained, batch weighing and metering system that delivers dry powder ingredients directly into a vacuum-conveying line with high accuracy and low cost, according to the company. The new pod system is suitable for the food and pharmaceutical industries, where a product may have a number of different ingredients that traditionally have been dosed by hand. The system can be made of one or any number of pods linked together via a common vacuum conveying line and a central controller. The ingredient is loaded onto each pod from flexible intermediate bulk containers (FIBCs) or sacked product. The system is sealed, so airborne dust is eliminated. — Ingredient Batching Systems, London, U.K. www.ingredientbatchingsystems.com
