Open-frame sigma mixers
Single sigma arm open-frame mixers from Shaffer-Bundy provide easy access for sanitation and routine maintenance. They are designed for mixing rotary-moulded cookies, crackers, biscuits, corn tortillas, muffins, sweet goods, granola bars and stiff fillings. Direct drives eliminate belts and chains and reduce maintenance as well as transmission noise and vibration. The agitator drive motor is either dual speed or variable-frequency drive.
