Anchor Products' new, automated packing line for filling bulk bags with sodium caseinate eliminates aeration experienced when using rotary sack fillers. In addition, it cuts dust and packaging waste by 90% and also achieves bag weight accuracy of an impressive 1 %.
Anchor Products is a part of the New Zealand Dairy Group. The organisation packs the sodium caseinate powder for export to a customer in Korea where it is used in the manufacture of coffee creamer.
The powder is transferred and filled by a system which features 2 flexible screw conveyors, a 1500 litre capacity surge hopper, and a bulk bag filler. The 1500-lb bags are automatically conveyed from the filler to a heat sealer, then to bulk storage. The PLC-controlled system ties to the plant PLC.
Anchor selected flexible screw conveyors as the most effective method to move this difficult-to-convey powder in a restricted 33 x 23 ft space.
The sodium caseinate powder enters the packing room from the blending area after being spray dried and milled to the correct particle size and transferred to a packing bin in a weighed batch depending on the order requirement.
At the control panel outside the packing room, the operator directs the powder either to the 4-station rotary packing machine to fill 20-25kg multi-wall sacks or to the Flexicon bulk bag filler.
