Evaluation of the filler was performed by the USDA's Dairy Grading Branch of the USDA/AMS/Dairy Programs Department.
Although a 3-A category for bulk bag fillers does not currently exist according to Sterner, the filler's product contact surfaces are constructed and finished compliant with 3-A standards.
The patented TWIN-CENTERPOSTTM design is said to maximize strength and improve accessibility to bag hooks while simplifying construction and reducing cost.
It is available with primary bag filling components for low cost, low volume
The filler is constructed of #304 stainless steel, and is equipped as standard with: manual fill head height adjustment to accommodate all popular bag sizes; pneumatically retractable bag hooks; inflatable cuff to seal the bag inlet spout; and feed chute outlet port for dust-free air displacement during filling.
Performance can be enhanced by adding: powered fill head height adjustment; port for inflating the bag prior to filling; automated vibratory densification/deareation system to maximize bag capacity and stability during storage and shipment; and powered or gravity roller conveyor.
The unit is offered with Flexicon's own flexible screw conveyor delivery system
Two configurations are offered: with filler mounted on load cells to measure weight gain of the entire bulk bag filler; and with weigh hoppers suspended above the filler, allowing higher filling rates through simultaneous recharging of the hopper and replacement of the bag.
