New Rise and Fall Bulk Bag Filler for delicate products

New Rise and Fall Bulk Bag Filler for delicate products A supplier of a mixed fruit and nut product in the Middle East needed a way to load 300 kg batches into Bulk Bags with no damage to his product, which contains whole walnuts - that are particularly fragile. Spiroflow has a long history of developing its ranges of Bulk Bag Fillers and Dischargers to meet the needs of individual customers. This was an excellent opportunity for us to apply our ingenuity and vast bulk materials handling experience. The result is a new ‘Rise and Fall’ model for our Bulk Bag Filler range. To avoid fruit and nuts having to fall the full height of an empty Bulk Bag, the bottom of the empty bag is raised up to just below the outlet of the filling tube. The gap between the two being just enough to allow the nuts to gently flow into the bag without damage. The bag is then gently lowered to allow filling to continue. The bag has to be lowered because flow of the fruit and nuts down the filling tube slows and stops due to the ‘self-choking’ action caused by the natural ‘angle of repose’ of the product as it exits the tube and spreads out. Accordingly, the bottom of the bag is incrementally lowered to encourage flow until it is filled to the desired weight. Following gentle vibration, the bag is ready to be removed. Of course the ‘Rise and Fall’ model can incorporate all of the standard ‘Spiroflow’ Bulk Bag Filler options such as weighing to OIML standards, bag inflation, displaced air filtration and gentle vibration to consolidate the bag contents. The latter makes them aesthetically pleasing and safe to handle, transport and store.
