How a Brewery Increased Production Capacity 50% in 2 Weeks

Brewery Increases Capacity by 50% in 2 Weeks

Process automation system upgrade and integrated software help craft beer maker meet growing consumer demand, improve quality and avoid high capital costs.

Ten years ago, tourists looking for a taste of the local life in Southern Canada might have asked for one of the region’s best wines. Now, it’s all about craft beer.

From entrepreneurial newcomers to large-scale producers, brewers in Canada are cashing in on the thirst for craft beer. The number of microbreweries — producing less than 25,000 cases of 24 — has more than doubled in the last seven years.

The explosion in craft beer popularity had one company — Sleeman Breweries — bursting at its production seams. The third-largest brewer in Canada, Sleeman brews and distributes popular beers from lagers to pale ales. With a notorious past in bootlegging and a brewing history dating back to 1834, the company has re-emerged as a powerful presence in the craft beer market. Sleeman operates three brewing production facilities located in Ontario, Quebec and British Columbia.

Modernizing Craft Brewing

At its Okanagan Spring Brewery (OSB) in Vernon, British Columbia, Sleeman was struggling to meet market demand for its OSB beers. The management team was looking for ways to increase output beyond the maximum eight brews per day.

If unable to increase production capacity at OSB, the company would have to build a new facility at a high capital investment cost. At the time, Sleeman used third parties to produce enough to meet customer demand — not ideal for managing costs, maintaining consistent quality and flavor, and meeting delivery deadlines.

Not only was the facility limited in its ability to increase production, the existing infrastructure was based on an antiquated, semi-automated control system. Changes to the brewing process —including adding new recipes — were made manually, which increased the risk of human error or inconsistencies. Throughout the production process, operators needed to be at the right place at the right time. If the operator wasn’t on the line to move production forward, brewing stalled.

These constraints limited Sleeman’s ability to respond quickly to changes in consumer taste or trends in the industry. The manual approach also hampered access to accurate and timely production metrics needed to fully control the brewing process. Batch reporting was ad hoc and required operators to input numbers on paper, limiting real-time access to critical information such as pressure and flow rates.

Better Control Means Better Brews

The Sleeman team worked with McRae Integration, a Rockwell Automation Recognized System Integrator, to design and implement an integrated process automation system to increase capacity, reduce risk and provide access to real-time production data.

The Sleeman team was hoping to standardize on one solution across its facilities. A single platform would allow executives to view production metrics and operations data for all facilities from the corporate location. With one common platform, in-house mechanics and electricians also could more easily transition from one facility to another and keep parts storage streamlined.

“A single platform would give us insights across the line and between facilities, so we could build on successes and meet our goals for continuous improvement while continuing to make great beer,” said Stefan Tobler, brewmaster at OSB. “We had already standardized on Rockwell Automation equipment at our other facilities, and knew McRae could help us meet our goals with a single platform based on the Rockwell Automation technology.”

McRae implemented a phased approach based on the PlantPAx® distributed control system (DCS) from Rockwell Automation and McRae’s own Meridian BrewSoft and BrewSight software, now FactoryTalk® Brew™ from Rockwell Automation.

The system includes reporting and historian software that collects, tracks and records key process data to pinpoint brew cycle trends, allowing operators to proactively make changes to brews as needed. The Rockwell Automation library of process objects provides predefined controller code and faceplates; this helps Sleeman operators more quickly configure new batches and build recipes. McRae customized the solution for brewing applications with its software, providing operators with complete control of the process through easily operated web interfaces.

Allen-Bradley® PowerFlex® 525 and PowerFlex 755 drives from Rockwell Automation deliver flexible motor control in the brewing process and help communicate device diagnostics to the control system.

To complete the implementation, McRae worked with Sleeman’s IT team to install VMware virtualized servers. The Sleeman team had implemented redundant servers at its Vernon facility a few years earlier, but found the costs of the equipment and additional storage space difficult to maintain.

VMware virtualized servers provide automatic redundancy for production data with enhanced data recovery and expanded data storage. One virtualized server can replace up to four physical backup servers, which decreases equipment hardware costs. It also provides the Sleeman team with the ability to create copies of the virtualized servers to run simulations offline and test production changes before they are made.   

Ready for More Beer

Within two weeks of the implementation, Sleeman increased production by 50% at its Vernon facility going from 8 to 12 brews per day.

Sleeman now can complete all brews on-site without using third-party producers, and avoided the cost of a new facility or significant equipment upgrades or additions.

Additionally, operators have gained more control over the brewing process. With web browser-based recipes, operators can more easily build a new recipe, create a test batch, and store the recipe in the system for additional testing and production. Brewing managers can simply make process and recipe changes via a web browser interface, without additional personnel.

Management can check on any production issues with PlantPAx system’s trending capabilities and the BrewSight software’s reporting. With exception reporting, the system creates reports to track progress as the brews reach fermentation and emails management if any brew variables deviate. The brewing team can take any corrective action needed and reduce downtime, rather than reworking and blending off the brew in small amounts later.

“Craft brewing involves a lot of small changes in recipes — based on water, incoming malt and other variables — plus adding new recipes,” said Tobler. “The PlantPAx system with FactoryTalk Brew software allows us to maintain brew quality, while also providing the flexibility we need to quickly respond to changing consumer tastes and market trends.”

The software upgrades have kept the brew quality high while increasing production speed. The Vernon facility now has an industry-leading, two-hour brew cycle, with improved consistency in flavor and quality.

The Sleeman team plans to implement the PlantPAx platform throughout the rest of the Vernon facility, including the tank farm and packaging lines. As the standardization across all areas of the company’s facilities expands, corporate visibility will improve, allowing the company to more effectively make decisions to help grow their business.
