The Fresco range of bulk bag fillers are designed to provide the highest accuracy and ergonomics while being robust enough to stand up to the harshest of environments.
Bulk bags up to 2000mm high and weighing 2000kg can be filled at up to 25 units/hr.
The simple double wind mechanism allows for quick and simple bag height adjustment by the operator to suit any bag size. Rear bag strap hooks that slide forward allow the operator to load an empty bulk bag from the front of the unit and immediately clamp the fill spout using our unique single-handed bag spout clamp. The bag straps are retained on the hooks and when filling is complete the hooks rotate 90° allowing for easy removal of the bulk bag by gravity, powered conveyor or forklift. Our bag inflator will inflate a bulk bag prior to filling, removing creases and folds which could cause irregular filling of the bag, making it unstable. The venture type bag inflator has no moving parts, reducing maintenance and is fully sealed during the bag filling process by a pneumatically actuated butterfly valve.
Displaced air is vented to a dust collector or vent sock during the bag filling process and is sealed off by a pneumatically actuated butterfly valve while the bag inflator is in operation. The densifying deck provides vibration to the base of the bulk bag during the filling process, ensuring the product is de-aerated as the bulk bag fills, providing a stable and compact bag. Discharge and infeed conveyors, including powered and gravity are available to suit your installations.
Fresco Systems manufactures a range of Bulk Bag Fillers and Unloaders.
Bulk bags or FIBC’s (flexible intermediate bulk containers) are an alternative to a one ton pallet of 25 kg paper bags or sacks.
A bulk bags is made of a woven polymer material which is sewn into a cube form with inlet and outlet spouts on the top and bottom and lifting loops at each of the top corners. Manufactured in various sizes and with various features bulk bags can safely store and transport most dry powders and granules in a dust free environment. A liner is sometimes used within the outer casing to retain product integrity and condition.
The Fresco Bulk Bag Filler has been proven worldwide to be instrumental in the safe handling of powders, granules and other materials used in almost every industry. Our fully flexible bulk bag filler allows for all bag sizes by the adjustable height fill head. Other features such as bag inflation, dust collection and densification deck allow for dust free stable filling to approved weights and measures standards.
The ergonomic, rapid filling of bulk bags coupled with the health and safety of the operators and the environment were some of the key factors in the designing and manufacturing of the bulk bag filler. The standard Fresco bulk bag filler design help to dramatically prevent the many back and respiratory injuries occurring on a daily basis. The bulk bag system facilitates safe transport of bulk materials across a factory or to the other side of the world without the need for operators to be exposed to hazardous dust or heavy lifting. The environmental benefit is reduced packaging particularly with the use of reusable and recyclable bulk bags.
Filling of the bulk bags is done by the operator placing the loops of the bag retainer hooks and clamping the infeed spout onto the filling head. Bulk bags ranging from 1m³ to 2m³ in capacity are then filled by the push of a button, which starts the infeed conveyor, and dust collector. During filling the densification deck vibrates the bag to provide a tightly packed bag for safe transportation. A forklift can then safely transport and store the filled bag without the risk of individual bags falling onto the forklift driver or passersby. This very simple operation completely protects the operator from handling or being exposed to filled 20 or 25kg bags of product. Potential stacking problems of bags on pallets is also eliminated.
Transportation of bulk bags is much safer than having many smaller bags stacked on a pallet. The load is much more stable eliminating the risk of loose bags falling while being elevated. This eliminates the risk of the forklift driver being hit by falling bags or from being exposed to the contents of a broken bag as well as reducing the risk of spillage polluting the atmosphere and environment. The bulk bags can be easily loaded into trucks or shipping containers by the forklift without the need to manually re stack product to achieve optimum space usage. This in turn means the recipient can also unload the material without manual handling. Bulk bags can be easily and safely stacked.
Once the bulk bag has reached it’s final destination the bulk bag is discharged using a Fresco bulk bag unloader. This can be of forklift or overhead monorail crane design. The operator fixes the lifting frame at ground level and the bag is lifted into position resting the base of the bag on the bag massagers while still supporting the top of the bag. The massagers also provide a safety barrier for the operator and gently massage the base of the bag to promote flow of the product assisting discharge. The operator can untie the spout of the bag in complete safety and control the flow of product via the bag closure valve. This also allows the operator to close a bag during discharge if only part of a bag is required. The fully enclosed dust tight design prevents hazardous dust exposure to the operator complying with OSH and EPA standards. The risk of foreign matter or objects including knives accidentally contaminating the product is also greatly reduced. Additional features can lift the bag while discharging to ensure all the product is discharged from the bulk bag prior to the operator lowering the bag to the ground and disconnecting it from the lifting frame.
For example 1 operator can easily and safely discharge a 1 tonne bulk bag in 5 minutes with no manual lifting or risk of exposure to dust. Whereas for the operator to discharge the same amount in 20kg bags the operator must lift 50 bags and place them on a slitting ledge where they must use a knife to cut the paper bag before lifting it again to discharge the contents. This would be expected to take 20 – 25 minutes with the added risk of back injury, lacerations, dust exposure and product contamination. The operator must then collect the empty bags and place them in the waste, which normally has no dust control. These bags then end up in a landfill. The bulk bags on the other hand can be reused or recycled.
The Fresco bulk bag fillers and unloaders are fully engineered, independently tested and certified as lifting equipment. The reduced operator input clearly creates a safer and more cost efficient working environment for almost the same capital cost as simpler manual powder handling systems.
