Several standard models of bulk bag fillers are offered. Any of these can be modified to fit specific product flow and bulk density characteristics. Our standard models are:
In order to achieve accurate weight control all of our standard units are equipped with a double gate valve which is activated by the Autopak controller for trim and bulk fill efficiency. When the bulk level is achieved as preset into the Autopak controller the first valve closes. This valve has a relatively small opening thus allowing the trim to conclude. The controller shuts of the second valve when the desired weight is achieved. The Autopak controller constantly corrects itself and averages the last three finished weights compared to the "standard" and corrects itself for more accurate finished weight control.
