From whole grain breads to gluten-free cakes, today’s mixers must handle it all without hurting the bottom line.
While mixers historically have had a fairly straightforward role in bakeries, operators are asking more of them than ever before in response to ongoing consumer demand for high-quality and specialized baked products. Manufacturers have their work cut out for them in delivering affordable, easy-to-maintain equipment that satifies production demands.
“Specialty items made from superior-quality dough such as artisan breads and scratch-baked foods continue to gain in popularity among customers in foodservice and grocery operations,” says Brian Kadel, general manager of mixing for ITW Food Machines (Hobart), Glenview, Ill. The popularity of specialized products with varied moisture contents ranging from gluten-free to high gluten to whole grain continue to present a unique challenge for mixer manufacturers. Still, operators’ top concerns remain straightforward: durable, reliable and easy-to-operate equipment that delivers high-quality mix consistency and offers safe and secure access for cleaning, he adds.
“Certainly on the industrial side, there is more movement toward multigrain or whole wheat,” says Jim Souza, vice president and director of industrial sales for Kemper Bakery Systems, North American subsidiary of WP Bakery Group, Shelton, Conn. He notes that this is not a new trend–going back at least a decade–and says that Kemper is well suited to meet these demands as a European-based equipment manufacturer. “The whole grain and rye breads have long been the staple in Europe. We’ve always had the equipment and it’s our standard, which can now accommodate the American markets, including those looking for increasing volume.”
However, Souza adds, “I think for the United States market, it is still going to be as it has been, which is the bigger, faster machines always win out. And depending on who the end customer is, for some markets it is just a question of the bottom line. What does the bowl cost? How do I get more dough out to produce faster with less labor?”
Steve Knauth, marketing manager of Munson Machinery, Utica, N.Y., says a common issue among high-volume operators is they purchase agitated blenders instead of rotary mixers, which can cause them headaches later on.
“While low-cost, all-purpose agitated mixers may be a good choice for some smaller baking operations, they generally are not when free-flowing bulk ingredients are being mixed in high volumes,” Knauth says. “Rotary mixers are more effective when handling free-flowing materials such as flour, whole grains, sugar and leavening agents in terms of complete discharge, gentleness, low maintenance, low energy consumption, rapid blending and sanitizing, uniform blending and uniform liquid additions.” He adds that agitated mixers tend to reclaim the initial savings through higher operating expenses on maintenance, labor and energy.
Also, operators face mounting energy costs amid a slew of new legislation pertaining to energy efficiency.
Kadel says that this factored heavily into the recently launched Hobart Legacy Series. “The Legacy mixer product line encompasses new drive technology that uses less energy and provides the performance that customers expect,” he says. “Testing of the new Legacy Series versus the classic Hobart mixer demonstrated energy saving up to 30 percent due to the new drive technology.”
Souza says that the sheer simplicity of mixing equipment helps control energy output and keeps cost down. “Mixers are kind of basic machines with only one or two motors, so we implemented high-efficiency motors,” he says, adding that a little attention on the part of operators helps, too. “Electronic controls allow you to control the speed of the motors’ mixing to an end result so you can dial in an optimum.”
