Brand leader Premier Foods has installed two Spiroflow big bag dischargers and four Spiroflow flexible screw conveyors to deliver Smash instant mashed potato to packing lines at its Histon site.
Previously, Smash made at Histon was held in storage hoppers and then transferred from the production area to the packing hall via an overhead conveyor belt system feeding four packing lines. With the Spiroflow equipment, Smash is now filled into and stored in 2m³ big bags. These are brought to the packing hall by forklift truck at the rate of 16 a day. The forklift truck removes empty bags and places full bags into position on the Spiroflow dischargers.
When lifted into place, the bags sit in the discharger on an annular flexible membrane. This forms a dust-tight seal around the base of the bag. The neck of each bag is pulled down through the aperture in the membrane and stretched over an upstanding spigot. This spigot is the inlet to the collection hopper below each discharger.
As product is discharged, and the big bags become lighter, springs within the big bag support arms raise the bags higher and higher to keep them taught and to ensure maximum discharge of the contents.
An alarm indicates when the bags are empty. The removal of the bags is a simple procedure during which they can be tied off to prevent dust escaping.
