The unloader features a SPOUT-LOCK® clamp ring that forms a high-integrity seal between the clean side of the bag spout and the clean side of the equipment. To promote total evacuation of material, a TELE-TUBE® telescoping tube maintains constant downward pressure on the clamp ring and bag spout, elongating the bag as it empties, while FLOW-FLEXER® bag activators raise and lower bottom edges of the bag into a steep "V" shape, directing material into the bag outlet spout.
Immediately above the clamp ring is a POWER-CINCHER® flow control valve employing a series of curved, articulated rods that cinch the bag spout concentrically, allowing dust-free retying and removal of partially-empty bags.
The flexible screw conveyors are said to handle a variety free- and non-free-flowing bulk materials including products that pack, cake, smear or easily degrade, with no separation of blended products.
Material contact surfaces of the system are of stainless steel finished to sanitary standards, with the exception of the polymer conveyor tubes which are removable for rapid, thorough wash down.
The floor hopper is available with a containment hood including integral dust collection for clean, safe handling of dusty materials.
Sanitary Weigh Batch System sources ingredients from bulk bags and manually dumped sacks, boxes and other containers, under automated control.
