Customized Auger Filler Funnel for Free-Flowing Products

All-Fill’s Eccentric Funnel Design process leverages 3D printing technology to rapidly prototype more efficient funnel designs to speed filling of free-flowing products.

All-Fill’s Eccentric Funnel Design process results in customized rotary auger filler funnels with offset pipes that eliminate the bridging that can occur with free-flowing products.

Most likely overlooked by passersby to the All-Fill booth, but an improvement that the company has been working on for the last year that has been shown to improve rotary auger filling speeds for free-flow products from 10% to 20% is its custom Eccentric Funnel Design process.

At PACK EXPO Las Vegas, All-Fill was showing one of its new funnel designs on a high-speed auger filling line, “but it’s one of those things that I feel goes unnoticed because you don’t often think about how a funnel can be better until it’s a problem,” shares Chad Martin, Engineering Manager for All-Fill.

According Martin, one persistent issue with free-flowing products has been their tendency to bridge, or basically clog, an auger filler funnel due to the way the product is nested or if it becomes a mass that can’t fit through the funnel’s hole. Says Martin, “Whenever customers run something like a whole peppercorn or rolled oats through one of our funnels on a rotary auger filler at high speeds, if they get bridging, they have to stop the process entirely or slow the system down so that there aren’t any issues.”
