Abstract:

A liner hoist for a bulk bag in a first embodiment includes a rope and hook for pulling up and tying the liner to prevent its fouling the discharge of material through a bottom pour spout. In a second embodiment, it retracts a liner upwardly from within a bulk bag as dry material is dispensed out the lower end thereof through a pour spout. The second embodiment includes a hook for hooking an eyelet fashioned in the upper end of the liner, a rope attached to the hook and supported by a plurality of pulleys from the bulk bag support framework, a spring extending between the rope and the framework, and cleat through which the rope is threaded to prevent the rope from retracting after the spring is tensioned. In operation, as the liner empties and tends to elongate, the hook lifts the liner from within the bulk bag through the action of the spring, all without operator intervention.

Abstract:

A liquid weigh scale hopper receives a plurality of liquid ingredients for dumping into a receiver/mixer and includes a pair of high flow rate spray nozzles near the top thereof for spraying chilled water into the hopper. As a discharge valve at the bottom of the hopper is opened, chilled water is sprayed into the hopper and fills it to create a gravitational pressure head helping to force the liquid batch out of the hopper.
