Planetary vs. Spiral Mixers: Which One You Actually Need
A spiral mixer is a bread specialist. A planetary does everything. And in a gluten-free kitchen, the spiral is a hard pass — here's why.
One of the most common questions I get: spiral mixer or planetary mixer — which one should I buy? People assume the bigger, more specialized-looking machine is the serious choice. It's not that simple.
These two machines are built for different jobs. Pick the wrong one and you've spent a lot of money on something that only does a sliver of what you actually need.
What a Spiral Mixer Is Actually For
Spiral mixers aren't bad. They're just specialists. A spiral mixer is built to do one thing extremely well: develop an intense gluten network in bread dough.
The spiral hook and rotating bowl work the dough gently and keep the friction heat low, so you can push a stiff, low-hydration dough hard without cooking it. If you're making rustic wheat loaves, bagels, pizza dough — real gluten breads, in volume — a spiral is genuinely great.
But read that back. It's great at developing gluten, in bread. That's a specific job. Outside of it, a spiral mixer can't do much for you.
Why the Planetary Does It All
A planetary mixer — your KitchenAid, your Hobart — is called an all-purpose mixer for a reason. The head stays put and the attachment travels around the bowl in a planetary path (hence the name), reaching everything.
Swap the attachment and it changes jobs:
- Whip — aeration: whipping cream, meringue, anything you need to build with air.
- Paddle — creaming butter and sugar, emulsions, batters, bringing a dough together.
- Hook — and yes, it makes bread too, with the right attachment.
Aeration, creaming, emulsion, batters, hydration, and bread. One machine covers almost everything a bakery does in a day. That's the whole pitch.
Gluten-Free Flips the Whole Question
Here's where it really lands for my kitchen. In a gluten-free facility, we're not trying to develop a gluten network — there's no gluten to develop. So the one thing a spiral mixer is built for is a thing we never do.
Gluten-free structure comes from two other places entirely:
- Hydrocolloids — xanthan gum and psyllium husk, which form the gel that mimics what gluten would have done.
- Starch gelatinization — the starches setting in the heat of the bake to lock the crumb.
Neither of those needs a spiral mixer. So in a gluten-free kitchen, a spiral is a hard pass. It's a specialist tool for a technique we don't use.
What to Buy When You're Starting Out
If you're a beginner, or you're just starting up your business: get a planetary mixer. It does the widest range of work, it'll grow with you, and you won't outgrow it the first time you make something that isn't bread.
I like KitchenAid or Hobart. Hobart in particular was made to last — I've had one since 1985, with barely any maintenance, and it's still kicking. Buy the machine that's still running in forty years, not the one that matches a specialty you may never need.
