Twin-bowl filling is just the ticket

Limited floor space was a factor as Heaven Hill Distilleries evaluated new filling equipment. It led to the Bardstown plant being the first to install a new kind of filler.

A twin-bowl gravity filling machine at the Bardstown, KY, facility of Heaven Hill Distilleries has made it possible to boost filling speeds from 180 to 220 glass bottles/min.

“It was time,” says Mike Monroe, Manufacturing Maintenance Manager, when asked why the new machine was installed. “Not only was the previous filler over 20 years old, it didn’t have an integrated capper. The capper was downstream, so we had some problems with splash and inconsistent fill levels. With this new filler we gain not just speed but accuracy to within 1⁄32 of an inch.”

Supplied by Fogg Filler Co., the Twin F6 Filler has two six-foot-diameter bowls each feeding 36 valves. It’s capable of 280 bottles/min, but limitations on other machines on the line make 220 the top speed at Heaven Hill.

“We believe we’re the first to install one of these twin-bowl systems,” says Monroe. “Our specific requirements made this a perfect fit for us.”

The requirements to which he refers have a lot to do with desired speed, narrow bottle necks, and a lack of available real estate in the plant. Increasing filling speeds to the 220/min mark was essential as new fillers were explored. But getting there with a conventional single-bowl filler is problematic because many of the glass bottles being filled have a long neck and a narrow internal diameter. This limits the size of the valve that can be used, and regardless of how big the valve is the flow of liquid is always somewhat choked off.

Also a factor is that some of the Heaven Hill spirits have considerable sugar content, which means there’s some foaming that takes place. “With a twin bowl approach,” says Monroe, “once we do half or two-thirds of the fill on the first bowl, the bottles then pass through a series of star wheel exchanges before they reach the second bowl. During this time, the foam has a chance to settle.”
