Quick looks at craft brewers

From introducing a next-gen ring carrier to pleading a case in the Illinois State Senate to improving the depalletizing process--it’s all in a day’s work for these craft brewers.

Fat Bottom Brewery uses its cartoning machine for both 12- and 16-oz cans.

Among the breweries that will be included in the group tours conducted each year during the Craft Brewers Conference convened by the Brewers Association is Nashville’s Fat Bottom Brewery. With a brand new 33,000 sq ft facility to show off, it’s easy to see why Fat Bottom was selected for this honor.

Central to the new plant is a new canning line for 12- and 16-oz cans. Comac supplied the overhead depalletizer, twist rinser, and Monoblock 8-1 filler (an eight-station rotary filler blocked with a single-station seamer). A Markem Imaje ink-jet coder puts date codes on can bottoms, and then cans are fed into a multi-lane conveyor that leads to a Spartan cartoner from Econocorp.

“As we thought about the new line we definitely wanted to be faster than the 25 cans/min that we were at before,” says Brewmaster Drew Yeager. “We’re now comfortably capable of 60/min on 16-oz and 75/min on 12-oz. The cartoner is fully capable of running at twice the speed we’re now at, which was one of the reasons we liked it so much. If growth continues and we need to add capacity, we can add a second monoblock filler/seamer and not worry about taxing the cartoner.”

Sterling Packaging Inc. provides the paperboard cartons fed into the Spartan cartoner. Routinely produced on the Econocorp system are 16-oz cans in either four- or 24-count formats and 12-oz cans in either six- or 24-count formats. “Regardless of which format,” says Yeager, “the cartoner picks blanks from the magazine, glues and tucks the flaps so they don’t get in the way, collates the cans into the right pattern, loads the cans with a pusher mechanism, glues the flaps closed, and discharges the finished cartons. It’s designed so that changeover from one format to another is easy, though I must admit doing it the first few times was a little intimidating. Now we have it down to about 30 min, and that includes operational tests.”

There’s a certain element of closing the loop in having Fat Bottom included on the Craft Brewers Conference tour April 30, because it was at CBC Portland in 2015 that Yeager and colleagues started seriously kicking the tires in terms of what gear they wanted to include in their new canning line. “We focused first on the cartoning system and sized most everything else accordingly,” says Yeager. “Because if the end of an automated line is not capable of keeping pace with what’s upstream, you have a serious problem. We looked at a number of cartoning options, and from the perspective of speed, price point, reliability, and willingness to communicate and support, Econocorp just stood out.”

Mobile canning
Now entering its sixth year in business, Chicago-based Begyle Brewing has been sending kegs to bars and restaurants almost from the beginning. Other packages the firm has used include 22-oz glass bombers and 12-oz glass bottles. But for the last year or so it’s 12- and 16-oz cans that have occupied much of the brewery’s attention.

Four “core beers,” as Begyle co-founder Kevin Cary calls them, are filled by copacker Great Central Brewing Co. But for special or seasonal beers, Begyle relies on Michigan Mobile Canning.

“They bring the cans, the equipment, and two people to run the equipment,” says Cary. “We just don’t have the space to keep a canning line here as a fixture. We’ve been bringing Michigan Mobile in about once a month for the past year or so, but now we’re looking to have them in twice a month. They run a batch, roll the equipment back into their trailer, and exit the premises. All we have to do is warehouse the cans and see to distribution.”

The line we viewed at Begyle (see video above) consisted of a depalletizer/single filler, an ink-jet coder for can bottoms, a twist rinser, a four-nozzle CO2 rinse station, a four-nozzle filler, a lid dropper, and a one-head seamer. A pressure-sensitive labeller owned by Begyle takes care of can decoration. Ring carriers are snapped on by hand and the four-packs are placed in corrugated trays that are palletized manually.

Production runs executed by Michigan Mobile, says Cary, range from 200 to 400 cases. Usually, he adds, it’s 16-oz cans. But later this year a sizeable run of 12-oz cans will be produced when Begyle brews a custom beer to celebrate the one-year anniversary of a Whole Foods store a few miles south of Begyle’s rehabbed 1930s-era factory near the Irving Park El stop on the CTA Brown Line.

Nex-gen ring carrier
Based in Boynton Beach, FL, and celebrating its sixth year in business in May of this year, Due South Brewing Co. recently switched to a new ring carrier for its six- and four-count cans of 12- and 16-oz beers. Rather than apply carriers manually as in the past, the firm installed a WaveGrip G1 carrier applicator. Especially suitable for applications where speeds are under 100 cans/min, the semi-automatic G1 is tailor-made for craft brewers. Making it all the more attractive to craft brewers--where floor space is at a premium and capital expenditure budgets are less than gaudy--is that it has a footprint measuring just 55 x 31.5 in. and it only costs about $18,000.

In view of all this, it’s little wonder that WaveGrip, part of the UK-based RPC Group, will be showcasing the G1 at the booth of Palmer Canning Systems at this year’s Craft Brewers Conference in Nashville, TN. Palmer is an authorized WaveGrip OEM that is producing the G1 and G2 WaveGrip applicators for the U.S. marketplace.

As with all WaveGrip applications, Due South feeds carrier material onto its cans by way of a large reel holding enough carriers for 3,000 six-packs. Cans exit a Cask five-head inline filler/seamer and are single-filed into a pneumatically powered device that, every time it strokes forward, pushes two cans at a right angle into the infeed conveyor of the WaveGrip applicator. As the force of each stroke pushes the two lead cans on this conveyor into the applicator wheel, the tops of the two lead cans are inserted into the WaveGrip carrier material. Exiting the applicator, an electronic blade cuts the packs into either four- or six-packs depending on the operator’s choice of settings.

According to Due South Brand Marketing Manager Doug Fairall, the switch to WaveGrip brought at least three benefits. First, applying ring carriers by machine requires fewer operators than the hand-applied approach used in the past. Second, the WaveGrip carrier costs considerably less than other options, including the hand-applied option the brewery used previously. And third, he says that consumers find it easy to remove a can from the WaveGrip carrier.

Which brings us to the makeup of the carrier itself. WaveGrip is part of British Polythene Industries PLC, which became part of RPC Group in 2016. The WaveGrip material is made at a BPI plant in the UK. Step one is a blown-film coextrusion of various grades of low-density polyethylene. Up to seven layers can be involved. According to WaveGrip’s Aaron McIvor, greater strength is imparted to the finished product by coextruding various grades of LDPE rather than producing a monolayer LDPE blown extrusion. Rollstock is then fed into a second operation that cuts out the holes for the cans, slits the rollstock into strips, and then winds the strips onto reels suitable for mounting on application equipment.
