Dry Powder Filling & Weighing Solution PROBLEM Need to replace old filling and weighing system that had seen long and regular service with an up to date, ATEX rated version capable of filling specialist packaging with a 50g, high degree of accuracy. Customer was keen to explore the latest options in filling and weighing system design that would benefit his operations both now and in the future. SOLUTION The final design showcases several bespoke modifications and non-standard enhancements and delivers one of the most accurate fill weigh systems completed by Hosokawa Micron Ltd. was achieved through close cooperation with the customer. An FDA and EMA compliant system, designed to achieve a 20g filling accuracy and capable of handling a range of specialist bag sizes. The unit is rated Zone 20/22, with easy to use, single control panel for all operations. The high degree of filling accuracy is delivered, through a modulating double valve which regulates powder flow from a preprocess IBC positioned above the filling and weighing system. To fill a range of small aperture bag sizes, in weights from 10kg and 35kg, the product chute is equipped with a purge line which fills the bag liner with air in order to keep it in shape for product acceptance. An exhaust hood extracts air as the powder falls into the liner during filling, preventing ripping of the liner which would result in loose product everywhere with detrimental loss of product and exposure of operators to harmful products plus the potential for dust explosions.
