Traditional Enclosed Frame Double Sigma Arm Mixer

High-Efficiency Mixing with the Double Sigma Arm Mixer

The Double Sigma Arm Mixer combines power and precision to deliver a consistently high-quality mix. Its agitators work in a thorough, uniform motion supplying a center of the bowl mix while creating high shear and a back-and-forth product movement. This ensures consistent distribution of inclusions like chips, nuts, chocolate chips and fruit.

Mixing capacity ranges from 450 to 4,400 lbs (204 to 1,995 kg).
