 FOR THE SAFE, DUST FREE DISCHARGE OF POWDERS AND DRY BULK SOLIDS
The worldwide acceptance of Bulk Bags has brought about big changes in bulk materials handling practices to the point where even the pharmaceutical industry are using them to replace rigid IBCs.
This is because Bulk Bags and, equally important, their associated filling and discharge systems offer proven advances in hygiene and “high containment” operation. At Spiroflow, we specialise in “high containment” Bulk Bag filling and discharge systems.
Range of bulk bag dischargers
T1 Simple Frame
Good H&S practice requires, as a minimum, that the weight of a bulk bag be supported as it is unacceptable to support bags from their loops for any length of time where operatives are present. Our Simple Support Frames are robust and can be constructed from epoxy painted carbon steel or stainless steel as the environment dictates. Bulk bag loading can be by fork lift truck or hoist.
T2 Universal
The Universal T2 discharger provides controllable discharge of product via an integral ‘Spiroflow’ conveyor coupled to the base of the discharger. The conveyor accurately meters the bag contents into a process vessel or packaging machine at a variable rate and in a totally enclosed manner.
T3 Loss-in-Weight
Total control of product dispensed from the bag is achieved by our T3 loss-in-weight discharger. The amount can be varied for individually selected batch amounts or interfaced with existing plant process control for continuous batch production requirements.
T5 Low Loader
Our T5 low loading discharger empties bulk bags in process areas with restricted headroom where only a low lift fork truck is available. The top section of the discharger is a removable frame on to which bags are loaded at ground level. The frame has fork channels at its base and needs only to be lifted a metre or so on to the discharger base.
T6 Integral Hoist
The T6 discharger is a self-contained unloading station for dust-free, controllable bulk bag emptying. It has an integral ‘I’ beam and hoist for loading bags into the discharger and is directly connected to an enclosed conveyor for direct transfer of product to process machinery. No forklift is necessary as the bulk bags can be brought to the discharger by pallet truck and stored adjacent to it ready for lifting into position.
T9 Total Containment
Our ‘Total Containment’ Bulk Bag Dischargers offer total control of big bags during discharge and their subsequent removal. They are complete with a liner spout clamping system that provides the highest level of containment.
T10 Pharmaceutical Discharger
Our pharmaceutical industry discharger offers containment levels as good as 25 ?g/m3. Lined bulk bags avoid cross contamination between batches and eliminate the need for and cost of cleaning/re-validation associated with traditional rigid bins. Releasing the neck ties, cutting open sealed liners, feeding them through the clamp ring and over the discharge spout all takes place within a negative pressure enclosure connected to a HEPA filtration system. Dependent upon the potency of the active ingredient, all this takes place either through an access door or through a sealed glove-box arrangement.
Mobile Bulk Bag Discharger
The heavy duty frame of our mobile big bag discharger, with optional towing facility and integral conveyor, offers the flexibility of materials discharging at several locations. (Not available on Type 6 with hoist beam).
