front and back seals from UHMW, and the sides seals are a polyurethane material. AMF Bakery Systems’ tilt and overtilt bowl mixers feature highquality sealing systems to keep the

dough in the bowl and the interior of cabinets clean, according to Bruce Campbell, executive product manager, dough processing technology, for the Richmond, VA-based equipment manufacturer.

MAJA ICE
The Bakery Ice
MAJA FLAKE ICE: Whether used with refrigerated mixing equipment or alone, ﬂake ice gives better front-end control resulting in consistent dough temperatures, higher product quality, and less waste. THE MACHINE: German-engineered and built to exacting speciﬁcation. Sanitary design, simple to operate, easy to maintain, and unbelievably durable. Pays for itself, whether you need a few pounds or several tons of ice each day.

Mr. Bartsch pointed out that openframe horizontal mixers inherently are easy to sanitize because there is less surface area and the supporting structures are much smaller. To improve sanitation on its mixers, Topos Mondial Corp. eliminated as many fasteners as possible because they can harbor bacteria and pathogens, according to Damian Morabito, president of the Pottstown, PA-based company.

Going to direct drives
Topos Mondial manufactures openframe horizontal mixers in singleand double-sigma styles as well as 3-roller-bar mixers with 800-lb capacities or less. However, Mr. Morabito said he’s not yet convinced that a direct-drive gearbox would hold up over time in a larger openframe roller-bar mixer. Mr. Bartsch noted Shaffer’s openframe design allows direct-drive technology to be used on horizontal mixers. “Direct drive has been a big factor for Shaffer and in what we have done over the past couple of years,” he said. Direct drives reduce maintenance by eliminating components such as pulleys, chains and idlers. “Your drive now is just your gearbox and motor,” Mr. Bartsch noted. “We eliminate the couplings between the motor and the gearbox and the overhung load from the output shaft of the gearbox.” All of Shaffer’s direct-drive mixers feature variable-frequency drives (VFDs). “VFDs made direct drive doable,” Mr. Bartsch said. “The startup torque on a 2-speed motor would cause the gearbox to chew itself up. With a VFD, we are able to do a soft start where you ramp up speeds, and it is a lot smoother on the gearbox.” AMF also developed a small line of direct-drive mixers that are simple and easy to clean, Mr. Campbell said. When redesigning its open-frame mixers, Shaffer wanted to drive out

FLAKE ICE lays ﬂat, eliminating the air pockets that cause ice to melt and stick together. Stays loose and light, making it easy to measure.

The SUPER-COOLED DRUM slowly rotates through the reservoir freezing water to its surface. Of all mid-sized ice makers, MAJA is the only one without an auger, grinder, bearings or other complex components that tend to wear out and break down.

CLEAN-IN-PLACE DESIGN with removable polymer reservoir ensures that purity is continuously maintained.
