Dough Mixers: Spiral or Planetary Mixer? The Guide
Good dough is craftsmanship – but not a hand cramp. A dough mixer kneads in 10–15 minutes what muscles would need an hour for, delivering reproducible quality. This guide explains the difference between spiral and planetary mixers and how to choose the right bowl size.
Spiral Mixer or Planetary Mixer?
| Criterion | Spiral Mixer | Planetary Mixer |
|---|---|---|
| Operation | Spiral hook + rotating bowl | Tool rotates within fixed bowl |
| Strength | Heavy yeast doughs, kneaded gently & cool | Versatile: stirring, whipping, kneading |
| Ideal for | Pizzeria, bakery, bread and pizza dough | Confectionery, sponge cake, creams, light doughs |
For pizza and bread dough, the spiral mixer is first choice: It develops the gluten network optimally without warming the dough – important for long dough fermentation.
The Right Size: Dough Capacity, not Bowl Volume
The crucial factor is the dough amount per mix cycle in kilograms. Rule of thumb for the pizzeria: A dough ball weighs approx. 250–280 g – so a 12-kg mixer can produce around 45 pizzas per batch.
| Dough Capacity | Pizzas per Mix Cycle (approx.) | Suitable for |
|---|---|---|
| 12 kg | approx. 45 | Snack bar, small pizzeria |
| 18–25 kg | approx. 65–90 | Pizzeria with full evening service |
| 38–50 kg | approx. 140+ | Delivery service, bakery, mass production |
Important: Also observe the minimum quantity – a large mixer cannot knead 2 kg of dough properly.
What to Look for When Buying
- Removable bowl: significantly eases cleaning and dough removal
- Connection: smaller models run on 230 V, large mixers from approx. 38 kg often on 400 V – check power connection beforehand
- Wheels: mixers are heavy; a wheel kit makes the device movable for cleaning
- 2 Speeds: slow mixing, fast kneading – preserves motor and dough structure
- The oven: dough and oven belong together – see our pizza oven guide and the complete pizzeria equipment
Frequently Asked Questions
Why does my dough get warm in the kitchen machine?
Household and planetary machines knead with high friction. Spiral mixers work more gently – the dough stays cool, yet the gluten network is fully developed.
Is a 12-kg mixer enough for my pizzeria?
Usually yes for up to around 100 pizzas in the evening (two to three batches). Those producing more daily or kneading in advance for long fermentation choose 18 kg or more.
How do I best clean the bowl?
Immediately after kneading with a dough scraper and warm water – dried dough is the main enemy. Models with removable bowls clearly have the advantage here.
