How big is big? Within a blink of the eye — 11 months to be exact — Wind Point and the Hearthside executive team merged these three companies to quietly become the nation’s largest privately held contract manufacturer with annual revenues in excess of $700 million. More than 5,000 employees currently work at 12 plants in seven states, where the company produces an array of snacks, cereal and baked goods, including cookies, crackers, croutons, stuffing, pretzels, rye and bagel chips, popcorn, snack mixes, bread sticks, toaster pastries, muffins and more. Its select, small client base consists of a who’s who of multinational corporations that hold many of the household brands in the snack, baking, food and retail industries. Odds are, millions of consumers have bought a product made by Hearthside during the past month, but they just didn’t know it.
“We’re building an organization that has size and scale, but the ability to be fast and more flexible than our customers are with their internal plants,” explained Dwayne Hughes, vice-president, supply chain, for the Downers Grove, IL-based company. “Our vision is to align ourselves with the premier food companies with our fast and flexible operation.”
Hearthside’s facilities range from a 60,000-sq-ft breakfast, granola and snack bar plant in Grand Rapids to the nation’s second-largest bakery in McComb, housing cookie and cracker ovens that are among the largest in the world. In addition to its large scale of production, its operations include flexible downstream packaging lines, ranging from bulk packing and rigid containers to single-serving bags and resealable pouches.
To become increasingly nimble, the company also operates a fabrication plant in Ohio, where it can modify any piece of equipment to add production versatility and create custom-designed products. Additionally, much of its production and packaging equipment is modular in design and comes on wheels to allow quick line setup or to reconfigure an operation to produce a new product.
“We have a breadth and scale of businesses — particularly in baking — that you don’t find under one roof, and those capabilities presented to a branded partner are immense,” noted Brian McNamara, vice-president, sales and marketing. “We might not be fast as the one-plant, mom-and-pop operation, but we are a lot faster than companies approaching $1 billion in size.”
In many ways, Hearthside’s business model involves resetting expectations on how the confidential world of contract manufacturing operates, according to John Weller, vice-president, operations, Grand Rapids. “Contract manufacturing was always thought about on a project-by-project basis,” he said. “You get in and get out with low cost. It was temporary. There were no programs and no sustainability of business. What Hearthside brought to the table was a strategic focus to the co-manufacturing world. The whole idea is to have a plan and strategy behind business growth and leveraging with our partners to continue that growth. It’s not a quick in-and-out, five-and-dime approach to business.”
With a focus on lean management, the company operates like a typical entrepreneurial manufacturer that can make quick decisions despite the operation’s large size, according to Mr. Hughes. “We’re not either one, but a combination of the two,” he said. “We’re entrepreneurial, but we’re large enough with the capabilities to play with the big guys. We’re a hybrid of both.”
Instead of focusing on selling its services, Mr. McNamara noted, Hearthside emphasizes how it can align its capabilities and manage its production flow to fulfill inventory and meet the future product development needs of its customers. “Selling is not what it is all about,” he said. “It’s certainly identifying who you want to partner with and how you can become a value-adding element to their supply chain.”
NEXT COMES BEST.
After developing its scale by putting three companies together to serve its customers who are among the biggest and the best in the food industry, the company then began rolling out its Hearthside Performance System (HPS). That continuous improvement program relies on extensive training and incorporates into its facilities best practices from across the food industry and methods borrowed from other industries. For example, those best practices might come from Toyota’s 5-S program (sort, set, shine, standardize and systemize), which establishes how everything must be in the right place for a lean operation to function properly, Mr. Hughes observed.
“What we’re doing is taking the best techniques of lean manufacturing, the best successes from Six Sigma and the best practices from Total Process Management, and we’re melding them into our plants as a co-manufacturer for the nation’s premier food companies,” he explained.
Any world-class manufacturing company, he noted, must have four principles: a vision and mission, self-improvement systems, a continuing education program for its workforce and a focus on providing value for its customers. Specifically, Mr. Hughes explained, Hearthside’s mission and vision requires the company to be a lower-cost producer than the premier food companies it serves. HPS established key performance indicators (KPIs) based on the foundation of safety, quality, service, cost and culture, and it began measuring each production line’s performance with the ultimate goal of each plant being a zero-loss operation.
To roll out its HPS program, Hearthside brought in every plant manager and supervisor for a couple weeks of boot camp, where they learned HPS terminology from industrial consultants and the metrics for measuring a production line’s performance on an ongoing basis. Additionally, the company has a toolbox of about 50 operational techniques and programs for improving a plant’s performance. Plant managers then can select anywhere from 10 or 12 tools and tailor them to their operation. Additionally, the program allows line operators to develop their own techniques and add them to the toolbox to enhance production.
“We told everyone, ‘If you have ideas or see how to do something better from your previous company, bring it in, and we’ll take a look at it,’” Mr. Hughes said. “If consensus agrees it’s a better idea, we may replace something else in our toolbox. We’re not forcing a prescribed process from a consultant who said, ‘Here’s how I do it. Here’s my way.’ We’re fluid with our program, and that’s the strength of the Hearthside Performance System.”
LEARN, DO, TEACH.
After boot camp, the managers returned to their facilities to implement these metrics to standardize operations across the company. They were expected to provide the leadership for starting up HPS and the training on down through the organization as a part of the company’s broader continuous education program based on a sustainable improvement process. “The program all starts with our plant managers. They own it. They lead it,” Mr. Hughes said. “It’s all about learn, do, teach. The philosophy is that everyone learns something or improves something every day.”
Each facility now has leadership and performance boards that track everything from waste to downtime to loss-incident rates. Located on the walls leading to the entrances of plant floors, the leadership boards list those people who are responsible for each line and for ongoing training to improve that line’s efficiency.
The performance boards monitor the operation’s KPIs on a 24/7 basis along with a green or red placard for each KPI on each production line during each shift. With downtime, for example, a green sign indicates the line operated at 85% or greater efficiency. A red placard indicates that the bakery needs to file an incidence report that identifies the root cause of a problem. The performance boards allow everyone in the operation to visually monitor how the facility ranks according to HPS expectations, and they help each shift know how the previous shift performed.
“You don’t need to understand our metrics as far as what determines green or red, but you do see how well or badly the bakery is performing,” Mr. Hughes said. “It’s a form of education that everyone can see from our employees to our CEO when he walks through a plant. You don’t have to ask a plant manager how everything is performing. It’s right there in front of you.”
By looking at the boards, even Hearthside’s customers can get a snapshot of how a facility is performing against the company’s expectations. “We were a little apprehensive at first, but the reaction has been very positive because [the customers] see we are being very transparent with all of our metrics and how we perform,” Mr. Hughes said.
The foundation for Hearthside’s continuous improvement program rests on the premise that the pace of an organization’s growth is set by the speed of its leaders. As a result, not every plant will be best-in-class at the same time, according to Mr. Hughes. Rather, each facility has a baseline and a strategy for enhancing its current performance level.
As a result, each plant is ranked as a lead, a mirror or a shadow site. Lead sites, or those bakeries that are furthest along toward performing on a best-in-class level, receive the most resources because they have the potential for the greatest return on investment. After developing new tools for best practices, the lead sites then transfer these tools to teach those bakeries that are mirror sites. Shadow sites, often the smallest bakeries, focus on benchmarking their operations against how the leader plants are performing.
RAPIDLY RAMPING UP.
In metropolitan Grand Rapids, Hearthside operates four facilities. Its lead site, H-1, houses 12 production lines that produce everything from croutons to cold-form bars in a 260,000-sq-ft plant resting on 15 acres of land. Its H-2 plant is a mirror site in a 152,000-sq-ft facility that houses six lines, producing popcorn, caramel corn, pretzels, bagel chips, rye chips, bread sticks and other components for snack mixes. Additionally, the H-2 plant’s two snack blending lines feed two vertical form/fill/seal baggers that mix, make and package a variety of Cheddar and other flavored snack mixes. The H-3 facility is a 40,000-sq-ft warehouse and packaging plant, and the H-4 operation is a 60,000-sq-ft shadow site that houses a cold-formed bar line.
Cold-formed bars, which are not baked like some snack bars, follow a similar process on several lines the various facilities. In the H-4 plant, which is one of the company’s most modern facilities, liquid bulk ingredients including corn syrup and yogurt coatings are stored in 48,000-lb tanks in a “hot room” that’s kept at 120°F. Instead of jacketing the two tanks with insulation, the company decided storage in an enclosed, heated room would be a more affordable option, noted Rich Roscoe, site supervisor of the H-4 facility.
Production begins when 2,000- to 3,000-lb totes of dry cereal and other ingredients are dumped into one of a battery of K-Tron material transfer bins, which each can hold one ingredient and allow Hearthside to produce a wide variety of bars with multiple components in them. Upfront, the process resembles that of a line making boxed dry cereal, Mr. Adler noted.
From the K-Trons, cereal and other dry materials travel up a bucket elevator to an A&B processing system with a 2,000-lb mixer where the dry ingredients combine with soybean oil and a slurry of liquid ingredients for flavor. The versatile system has a Grote kettle for heating oil and other minor liquid ingredients as well as an ancillary kettle for heating or cooking other liquid ingredients. Although the line has an Allen-Bradley PLC recipe system, mixer operators also have paper backups for formulas as the company continues to adapt more automated controls, according to Mr. Roscoe.
The batch then transfers to the hopper of a Hosokawa Bepex slab former with three adjustable rollers to create the proper height, width and speed of the slab. After traveling through compression rollers to ensure the correct size and weight of the bars, the slab moves under a Woody Stringer to receive drizzle or zigzag decorative icings or coatings. Here, an optional Sollich Enromat can be rolled over and added to the line to coat the bars in chocolate or vanilla, if the formula calls for it. After traveling through a 100-ft, glycol-chilled cooling tunnel set at 40°F, the slab travels through a rotary cutter that slices the slab into 28 rows and then to a guillotine to create the bars before they enter a cooling conveyor.
Next, the bars pass through a Safeline metal detector and are directed, aligned, indexed and travel in single file through one of four Campbell horizontal flow wrappers. The packaging area also has a fifth wrapper that serves as a backup system or can be used for bulk products. The bars then feed into a Bradman Lake cartoner before the boxes are sealed and code dated. To ensure accuracy, the cartons travel over a Toledo checkweigher prior to manual case packing and into an automatic ABC case sealer. Case packing isn’t automated because the lines regularly produce numerous bar and packaging sizes, Mr. Roscoe said.
SNACKS TO THE MAX.
In the versatile H-2 snack facility, the bakery has four 100-ft ovens, three of which are 48 in. wide and another that’s 80 in. wide. Flour from three 210,000-lb MAC Equipment silo systems feed the lines, each of which is staffed with only eight to 10 operators because the systems are so efficient, according to Steve Slater, plant manager. After traveling through a Great Western sifter, flour enters one of three continuous mixing systems. One mixer feeds the first two lines that make breadsticks, swizzles and other components, while the second mixer feeds the pretzel line, and a third supplies the bagel and rye chip operation.
Pretzel production demonstrates how versatile and efficient Hearthside has become. Here, an Exact continuous mixer from Reading Baking Systems cranks out 4,000 lb of dough an hour. Flour is first combined with oil and water plus a salt slurry and yeast to create a premix that moves into the unit’s development barrel, which cycles out a 4-lb piece of dough about every 20 seconds.
According to Mr. Slater, the continuous mixing process reduces labor, eliminates formulation errors and quickly adjusts flour and yeast to provide greater dough consistency essential to making delicate, crisp products. “You can increase or decrease the dough flour on the fly, and you don’t have to wait until the next batch to do it,” he said. “With continuous mix, you get the operation running smooth, and you just have to make little adjustments downstream to fine-tune any production.”
The dough chunks then travel to an extruder feeding a unique double-row die cutter running 265 cuts per minute and capable of producing two differently shaped dough pieces simultaneously. “We’re just laying and running the line on maximum speed,” Mr. Slater said.
Traveling along a 100-ft proofer conveyor naturally ferments the yeast prior to the pieces entering a sodium hydroxide caustic bath that will eventually give the pretzels their brown shell after baking. The pliable pieces are hit with a dash of salt before baking in the 2-stage oven for about 12 minutes. First, the pretzels are baked on the 100-ft tunnel oven band to attain their color, and then they loop back underneath the band into a dryer section to eliminate excess moisture and attain their crispy texture. After a brief cooling period and metal detection, the pretzels travel down a tube conveyor, which gently drops them to a plastic-lined bulk container.
On the bagel and rye crisp line, which produces a multitude of components for snack mixes, 18-in. loaves bake on Reading’s signature 80-in.-wide oven line. To streamline operations, Hearthside invested in a Stewart Systems spiral cooler to eliminate labor- and space-intensive rack cooling of the loaves. The line now operates with cooler feeding an Urschel slicer ahead of a National dryer to produce the components. “We used to have a crew of 15 assigned to this line, and now, we run it with just two people,” Mr. Slater said. “We not only took the rack out of the process, we took out the labor. The old way was expensive for us, and moving all of those racks just elevated the risk for injuries and product breakage, so we made it a clean operation to make it more efficient.”
To improve its cost structure, Hearthside needed to understand its capacity needs and how to adjust production lines to establish their maximum throughput. The company relied on theoretical max studies, which start with the OEMs’ benchmarks on capacity and throughput. The studies then identified the choke points on the line to determine where to fix or invest in the operation to increase capacity. For example, a pretzel line that had been running at 4,500 lb an hour, based on an equipment manufacturer’s recommendations, actually might have a theoretical max of 5,200 lb an hour when all of the choke points are removed, according to Mr. Hughes.
Food safety also is a prominent component of its continuous improvement process. By the end of the year, Mr. Hughes said, all 12 of Hearthside’s production facilities will be rated SQF Level 3, the highest level available from the Safe Quality Food Institute as a part of the Global Food Safety Initiative.
Additionally, the company is rolling out SAP, an enterprise resource planning system, across all of its plants to better integrate scheduling and operations, to further lower its costs and to improve the customer service it provides its big-time customers. “SAP is an enabler tool, providing real-time data that will allow us to be more flexible on our feet,” Mr. Hughes said. “HPS is all about managing around data and relying on data to tell you where to focus your efforts and resources.”
For the 2-year-old company, he added, that focus remains on improving its quality and service in the way that puts the business into a class of its own.
“It’s a journey to be a world-class operation,” Mr. Hughes said. “It’s not a destination. That’s where our beliefs are, and we’re building our system around the ability to demonstrate continuous improvement year over year.”
