Commercial spiral mixers develop dough by rotating both the bowl and a spiral hook, producing well-developed gluten with low temperature rise. They are the working bench mixer for pizzerias, bakeries and bread programs. Hospitality Connect stocks single- and two-speed spiral mixers from Hakka, Mecnosud and Brice, in 10kg through 50kg flour-capacity bowls.
Types of spiral mixers
- Single-speed: Entry models for mid-volume pizzerias; consistent kneading speed and reverse on bowl rotation.
- Two-speed: The standard for bakeries — first speed mixes, second speed develops. Better gluten formation, cleaner dough.
- Removable bowl: Lift the bowl on a trolley and walk it to a divider/rounder — speeds up changeovers in production bakeries.
- Self-tipping bowl: Tilt-out bowl design dumps dough to bench in seconds — best for high-volume pizza programs.
- Heavy-duty production: 50kg+ flour bowls with three-phase motors; for production lines running 200+ pizzas/day or large bread runs.
Sizing and dough capacity
Spiral mixers are rated by flour capacity, not dough capacity — total dough mass is roughly flour rating times 1.6 (60% hydration). A 10kg flour mixer produces ~16kg of pizza dough per batch (60–80 medium pizza balls). 25kg flour mixers produce 200+ pizza balls per batch. Don't underfill — bowls below 30% of rated capacity won't form dough properly. Match the mixer to your peak shift production with 20% headroom for surge.
Operating considerations
- Power: 10–15kg models run 10A 240V; 25kg+ moves to 15A or three-phase.
- Bowl seating: Removable-bowl models need a level floor and clear path for the trolley; consider this in bakery layout.
- Dough temperature: Spiral action keeps dough cooler than planetary mixing — most batches finish at 24–26°C without ice.
- Cleanout: Wipe the bowl and spiral hook between batches; weekly deep clean of the breaker arm and seal.
Spiral mixers reward correct sizing more than any other bakery machine. A 25kg unit running 8kg dough overworks the spiral against the bowl wall and tears gluten; a 10kg unit running 9kg won't reach proper development before the motor cuts out on overload. Match flour capacity to your standard batch and run the mixer at 60–80% of rated capacity for best dough development. Two-speed models give better control: first speed for hydration and ingredient incorporation, second for gluten development. Plan dough out-temperature with autolyse and ice — spiral action keeps dough cooler than planetary, but high ambient kitchens still need iced water in summer.
