Spiral mixers are named after their spiral-shaped dough agitator. The bowl revolves during mixing while the agitator stays in place. It terms of dough capacity spiral mixers can handle a much larger volume as compared to their planetary cousins. Commissaries and bakeries most often use spiral mixers, but medium to large volume pizza operations can also find a spiral mixer useful. We often have these available for customer in reconditioned units. Please call or email for sizing and pricing.
