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.

Hoist for retracting a liner from a bulk bag as material is dispensed

A batch weighing apparatus includes a plurality of soft sided bulk bags containing a quantity of bulk dry material which are rack mounted thereon and which have generally U-shaped bracket assemblies mounted thereunder for agitating the material in the bulk bag for free flow therethrough. The plurality of bulk bags are used in place of the rack mounted bins in prior art devices and permit shipment, storage, and dispensing of bulk dry material from the same soft sided bag.

Batch weighing apparatus with bulk bag type bins

A receiver arrangement includes a bin vent for collecting ingredient dust and a multiple tee arrangement which permits the connection of a minor/micro pressure blow transfer system for dry ingredients into the major pressure blow system which transfers major ingredients into the receiver. A bottom diverter valve at the top of the receiver permits these ingredients to be directly transferred into the receiver, or to be transferred into the bin vent for addition at a later stage of the mixing process. The receiver and bin vent are supported by load cells to continuously monitor the weight of ingredients contained in the receiver/bin vent so that proper amounts of each ingredient are reliably included in each batch. Three different embodiments are disclosed.
