The best for today and beyond
by Dan Malovany, Baking & Snack
When Papa Pita Bakery reached capacity three years ago, Farzad Mohebbi knew the company hit a critical crossroads that would determine the direction of the business for years to come. Option No. 1? He could play it safe and expand the 50,000-sq-ft facility located on four acres just a stone’s throw from Salt Lake City’s airport.
That was certainly a tempting alternative. “We had no debt and a thriving business at that time, and I was living a comfortable life,” said Mr. Mohebbi, president and CEO, who owns Papa Pita with his wife, Yolanda. “I could have taken the easy road out.”
Option No. 2? He could place a huge bet and put it all on the line. “The gambler in me said, ‘Let’s do it the right way,’ ” he recalled. “We didn’t need to do it. It was a matter of wanting to do it and believing we can do something spectacular.”
Two personal factors motivated him to take the leap. First, Mr. Mohebbi wanted to build something special for his family, specifically for his daughter, Maya, and son, Kiyan. “I was rejuvenated by my two young children back then. The old saying ‘children keep you young’ had a whole new meaning for me having a 7- and 8-year-old who are just incredible,” he said.
Second, Mr. Mohebbi felt he owed his employees who had worked with him and stood by his side during the ups and downs over the years. “I get goose bumps when I talk about my children and my team,” he observed. “I have some very loyal people who have been with me for years. They shared in our vision, and they felt there was nothing that we couldn’t do together. I wanted this for them as much or more than for myself.”
Today, that vision has become reality. The new 200,000-sq-ft facility in West Jordon, UT, produces flatbreads, tortillas, bagels, buns and premium sandwich breads, and it has the capacity and versatility to meet anything the market can envision for years to come.
That is no exaggeration, according to Mr. Mohebbi. Relying on his engineering background and decades of experience, he personally oversaw — no teams of engineers or consultants at his side — the design of the new bakery that will eventually house five makeup systems feeding three tunnel ovens.
By using multiple makeup lines to feed two of the three ovens, the bakery can adjust its schedules, move its existing makeup lines or adapt its production lines to ensure the bakery’s ovens are kept full as customer demand for one product increases or wanes.
“One thing that was big on my mind when I designed this bakery was to have the flexibility not only to make our products today but also to make the products of tomorrow,” he said. “Most companies put themselves in a box with a budget and tie their lines to specific products. My knowing the spectrum of the product line and envisioning a production line that can do any and all of those products in an efficient manner was key to designing these lines. It’s not just a flatbread line.”
Additionally, he noted, when investing in the ballpark of $50 million, a family-owned bakery needs to keep every potentially foreseeable — and unforeseeable — option open and demand attention to every detail. In dealing with suppliers, Mr. Mohebbi vetted, negotiated and even haggled to make sure that he got the biggest bang for the buck. Although he calls himself a gambler, he did everything in his power to minimize his risks.
“Instead of telling them what I wanted built, I got a list of everything they could build or have built in a system,” he said. “I went to each manufacturer and said, ‘I want you to build me the very best and don’t stop there. I also want to add this, this and this.’ I negotiated everything up front.”
In some cases, Mr. Mohebbi went against vendor recommendations. In the end, however, he felt he got the best they could offer. “Two years later, several manufacturers came out and said this is the best line they ever built,” he said. “They will incorporate many of the things they’ve done here into their standard design because they see how much better it performs and how it improves the product. We didn’t want to be just another bakery. We want to be a great bakery.”
Take the bakery’s Rademaker 48-in.-wide flatbread line installed last year; it can crank out 100,000 round thins per hour. The capacity is so large that the line has a dedicated proofer and Babb tunnel oven and needs two spiral coolers just to handle the volume.
Moreover, Mr. Mohebbi noted, the versatile line can create almost any form of pita, lavash, pizza crust, naan, thin bagel or any other specialty thin bread that becomes the next big thing in the market. How? Of special note, it employs rotary cutters and scrap recycling systems that come both before and after the proofer.
Why’s that? “Some products may change shape during the proofing process, and they need to be cut and made up after proofing to obtain the strict consistency our customers want,” he said. “And we never know what products we’ll need to produce five years from now.”
Its bagel line, which features a BakeTek makeup system, started up this May and turns out 30,000 to 40,000 pieces per hour, depending on their size, and it doesn’t matter if the customer wants them boiled, steamed or anywhere in between. “We have the ability to completely submerge and boil bagels or just apply a waterfall or even bypass the system and steam them,” Mr. Mohebbi said. “Or we can do a combination of any of these.”
In the near future, Papa Pita plans to add artisan roll makeup equipment to create a combination line. The move will maximize throughput of the Capway proofer and Babb stone-hearth tunnel oven and allow the bakery to expand its product portfolio for both the retail market, which makes up 75% of its business, and the foodservice channel.
Feeding the third Babb oven is the Gemini Bakery Equipment variety bread line, which began production this spring and features a double-pressure board system that can make a full range of high-end specialty breads from 60 to 120 loaves a minute. During Baking & Snack’s exclusive visit in June, Papa Pita just began installing an AMF conventional bun line that makes 600 pieces a minute and shares oven space with the bread line.
Speed, capacity and versatility are just part of the bells and whistles built into this bakery. Mr. Mohebbi also invested in sanitary designs and in reducing maintenance, eliminating downtime, increasing food security and adding process controls that will continue to pay benefits in the long run.
Those important little things
In 2008, Mr. Mohebbi told Baking & Snack that success for Papa Pita comes down to monitoring, controlling, fixing or improving the little things. As they say, the devil is in the details. (For a history of the company, see Baking & Snack of December 2008, available in digital edition at www.bakingbusiness.com.)
Some of those little things are just common sense. Managers, for instance, are located near their areas of responsibility. Corporate offices are in the front, operations in the middle of the bakery and sales in the back near the warehouse and distribution center.
Then again, some of those little things are not that small. Take the bakery’s straight-line production flow. “It’s almost a dream to have a bakery with wide aisles between lines and totally straight,” Mr. Mohebbi said.
Many companies talk the talk about sanitary design. Mr. Mohebbi walks the walk, and that’s not a little thing in today’s world. “The majority of our lines are, back to front, all stainless and all washdown, and everywhere possible, we used servo motors to avoid chains that can break down,” he noted. To minimize spare parts inventory, Papa Pita worked with only a handful of vendors that Mr. Mohebbi personally vetted. He insisted all PLCs, HMIs and electronic controls come from Allen-Bradley. “If I have to change one HMI, I don’t want to have 50 different types on the shelf,” he explained.
His attention to detail can be seen with even something as prosaic as a proofer. Mr. Mohebbi wanted a proofer that was much bigger and much brighter so that when maintenance personnel needed to make a repair, they could replace or maintain everything as quickly as possible. In the long haul, he said, downtime costs bakeries much more than initial investments. Often, he added, downtime is never considered as a variable when calculating ROI on a major project.
“When your proof box goes down and you have to change something — or if you can’t wash it daily or fix it easily — chances are that it will not be washed properly and will not be maintained properly,” he said. “Your breakdowns, your downtime and the cost of repairs are many, many, many times more than that incremental cost of running it.
“One of my requests is that I want to walk into my proofers with my sunglasses on and be able to see everything because it’s so bright,” he said. “Everybody makes their box like it’s a dark hole. You go in there, and you can hardly see because the people who designed it never have worked in that box. I wanted to get in, see what’s wrong, fix it and get out because it’s hot in there.”
Inside a brand new bakery
With the opening of the West Jordan, UT, bakery, Papa Pita now employs 200, more than triple the 60 it had two years ago. Production at the bakery runs five days a week with extensive sanitation and preventive maintenance on down days. Spending $50 on replacing a bearing today can save thousands of dollars in labor and wasted product if the line goes down.
Flour is stored in three silos with 170,000 lb of capacity each and delivered through a Great Western Manufacturing sifter. Papa Pita worked with Horizon Systems to automatically deliver flours and 14 other essential ingredients — ranging from bulk oil and sugar to salt and other minors — that are found in most of the bakery’s products, directly to the mixers.
To provide front-end control and eliminate human error, the bakery relies on a Northwind recipe system that monitors all ingredients, provides automatic lot tracking and protects proprietary formulas. There’s no under- or over-scaling here. Only yeast and a few other minor ingredients are added manually. If a supervisor or operator attempts to adjust or change a formula out of spec, an email alert is sent to Will Durrant, plant manager, and Bryan Malkin, operations manager. At the end of the day, the software turns out a report to assist in ingredient costing, purchasing and inventory.
Two Shaffer 2,000-lb open-frame dough mixers can interchangeably supply the flatbread and bagel lines, depending on production flow. Mr. Mohebbi selected the mixers because of their energy efficiency and sanitary design. “They look like Transformers on four big legs that make them easy to wash,” he said.
On the Rademaker flatbread line, dough travels out of the mixer and up an inclined conveyor to an extruder and several multiroller reduction stations, a cross roller and gauging stations. After passing through the first rotary cutting station, dough pieces ride along a variable-height bridge that feeds the Rademaker cascading proofer, which automatically adjusts the dough’s path of travel according to the required proof times.
For longer proofs, the bridge feeds dough pieces to the top of the proofer. For shorter proofs, the bridge lowers to the middle level or to the bottom for little or no proof. The line can even run a dough sheet through the proofer, and a second set of rotary cutters creates the dough pieces.
Each level of the cascading proofer comes with its own servo motor to adjust its speed. This added feature may seem redundant or over-engineered at first because many proofers operate with only a few single-drive motors. However, Mr. Mohebbi said he insisted that Rademaker include this feature because it not only provides further control of proofing times but also allows better control of the product’s shape during transfer from one layer to another.
The Babb 96-ft, direct-fired oven can reach 1,000°F. The expandable modular oven features a steam chamber, if items need steaming, and an inspection system to monitor color and the size of products.
All of the bakery’s IJ White spiral coolers come with clean-in-place systems and belt sanitizers to minimize cross-contamination. A sloped floor beneath the coolers allows foam and water to drain, dramatically reducing cleaning time. “It used to take us 30 to 40 hours to clean them,” he said. “Now it’s done in 20 minutes.”
Flexibility and reliability
The combination bagel and roll makeup line features a five-pocket piston divider that feeds five bagel formers with the pieces dropped via a reciprocating conveyor onto 32-by-48-in. peel boards. An ABB robot with a gantry storage system loads and unloads peel boards.
Once again, the proofer is integral to the line’s flexibility. When the peel boards enter the Capway CapStep proofer, they rise upward then transfer to a downward system. According to Mr. Mohebbi, the space-saving system can handle products ranging in height from 1 to 7 in., thus accommodating everything from bagels to bread bowls for soup. Proofing times are also adjustable. “Most companies proof dough within 45 minutes to an hour. Our proofing times are much, much longer,” he noted. “Some of them are 50% longer than normal.”
After proofing, the bagels enter the water bath and waterfall system, or they can bypass it to create softer steamed bagels. The Babb 100-ft oven features the same options as the one on the flatbread line, except it has stone hearth side walls and a maximum temperature of 700°F.
The variety bread line also provides extensive versatility. Sponges are created in a Shaffer 1,300-lb mixer then receive up to a 4.5-hour ferment in a conventional first-in, first-out fermentation room before entering a third Shaffer 2,000-lb dough mixer.
“One of the things that is important to us is to stay true to our process and not be tempted to cut steps for efficiency and speed,” Mr. Mohebbi explained. “Although we run at the highest rates, our process still manages to keep a long natural fermentation that creates good flavor.”
The Gemini Bakery Equipment makeup line features a WP Haton single-pocket divider and WP nonstick cone rounder that uses light warm air to round doughs without flour or with a slight dusting of flour or a dab of oil. Dough pieces then travel under two pressure boards that can be combined to produce a wide variety of textured products. A topper between the boards allows seeds and grains to be rolled into the dough pieces as they travel under the second pressure board and are then panned.
After traveling through the CapStep proofer, similar to the bagel line, the pans pass under a Burford seeder and into a Babb 100-ft air-impingement oven. The washdown oven can reduce bake times by up to 30% while lowering energy usage by 35%. The bakery can control not only bake times and temperatures but also convection velocities and the heat above and below the hearth.
Of special note, Mr. Mohebbi said, is the oven’s ability to raise or lower temperature by 150 F° in two minutes, which streamlines changeovers. “We can bake one pan or an oven full of pans without heat flashing,” he said. “Every loaf is the same color. This is a huge advantage on a combination [bread and AMF bun line] and reduces waste tremendously.”
The empty pans travel on a Capway conveyor through a 50-ft tunnel that cools them from 375°F to about 95°F. Specifically, ambient air blows through the tunnel to remove the heat from the pans. This system provides the necessary cooling as the pans recycle back to the front of the line so as not to shock the dough pieces prior to entering the proofer. Meanwhile, the warm loaves travel along an IJ White spiral cooler and on to packaging.
At this year’s International Baking Industry Exposition, to be held Oct. 6-9 in Las Vegas, Papa Pita will look for additional ways to streamline its packaging operations. Currently, the packaging department features a battery of UBE baggers and slicers and Kwik Lok closure systems. All systems can be washed down, but most of the tray loading and basket stacking remains manual. The bakery also casepacks products for foodservice accounts and stores them in a 160-pallet freezer.
In addition to continuous investment, Papa Pita plans to focus on continuous improvement, noted Mr. Malkin, a start-up specialist and expert in lean manufacturing who’s worked at multinational corporations throughout his career.
Ramping up the flatbread line, he acknowledged, involved a pretty large learning curve since the old bakery had a lot of rack ovens and was much more manually operated. The bagel and bread lines, however, came online much faster. The next step will involve ongoing training to lower costs further and improve the operations’ efficiencies. “We’re driving down the idea that every second of operation uptime counts,” Mr. Malkin said.
Mr. Mohebbi said he couldn’t have completed the project without his key suppliers. “I had one thing in common with all these vendors: They are owned by an individual like me, and their personal relationship commitment to excellence and promise to me was the key factor in choosing them to build my new bakery, and I sense that they are just as proud of the end result as I am,” he said.
And, of course, he thanked his management team. “I could not have done this without their tremendous hard work, countless hours of stress and sleepless nights and the dedication and passion they have poured into this two-year project,” he said.
