A mixer is one of those pieces of equipment that either sits unused in the corner or runs all day. For other essential equipment, see our guides on commercial ovens and commercial ranges. The difference is buying the right size and type for what you actually make. Too many restaurants buy a 60-quart mixer because "we might need it someday" and then use it twice a week to mix pancake batter. That's a $5,000 paperweight.
I've seen bakeries buy a 20-quart planetary mixer when they opened. Within 6 months, they were making 200 pounds of bread dough per day. The 20-quart couldn't handle it. The motor overheated. The dough hook struggled. They upgraded to a 40-quart spiral mixer. Mixing time dropped from 12 minutes to 6 minutes. Dough quality improved because the spiral action developed gluten better. The 20-quart was the right mixer for the restaurant they thought they'd be. The 40-quart spiral was the right mixer for the bakery they became.

Planetary Mixers
The most common type. The mixing attachment rotates around the bowl while the bowl remains stationary. Named for the planetary motion of the attachment. Versatile. Can mix, whip, and knead with different attachments.
Best for: general-purpose mixing (batters, sauces, fillings), whipping (cream, egg whites, meringue), light dough (cookie dough, cake batter, pastry), mashed potatoes, compound butter.
Not ideal for: heavy bread dough (the planetary motion doesn't develop gluten as efficiently as a spiral mixer), high-volume dough production.
Spiral Mixers
The bowl rotates while a spiral-shaped hook remains stationary. This motion mimics hand-kneading and develops gluten more efficiently. Produces better bread dough with less heat buildup.
Best for: bread dough, pizza dough, bagel dough, any high-gluten dough, high-volume dough production.
Not ideal for: whipping, general mixing, anything that doesn't require dough development. Spiral mixers only have one attachment (the spiral hook). They can't whip cream or mix cake batter.
Vertical Cutter Mixers (VCM)
A high-speed mixing bowl with blades at the bottom. Can chop, mix, puree, and emulsify. Not a traditional mixer. More like a giant food processor.
Best for: large-batch chopping (vegetables, nuts, herbs), pureeing (soups, sauces, baby food), emulsifying (mayonnaise, vinaigrettes), mixing (meatballs, meatloaf, fillings).

Spiral Mixer Sizes

20-30 pound: Small bakeries, pizza restaurants making dough daily. Price: $3,000-6,000. 50-80 pound: Medium bakeries, high-volume pizza. Price: $6,000-12,000. 100-150 pound: Large bakeries. Price: $12,000-25,000. 200+ pound: Industrial. Price: $25,000-50,000.
Attachments
Planetary Mixer Attachments
Flat beater: for general mixing (cake batter, cookie dough, mashed potatoes, compound butter). Wire whip: for whipping (cream, egg whites, meringue, light batters). Dough hook: for kneading (bread dough, pizza dough, pasta dough). Pastry knife: for cutting butter into flour (pie dough, biscuits, scones). Splash cover: prevents ingredients from flying out of the bowl.
Most mixers come with the flat beater, wire whip, and dough hook. The pastry knife and splash cover are usually sold separately.
Spiral Mixer Attachments
Spiral mixers typically only have the spiral hook. Some models offer a removable breaker bar that assists with dough development. No whip or flat beater options.
Top Brands
Hobart
The industry standard. Made in the USA (legacy models) or China (newer models). The N50 (5-quart) and HL120 (12-quart) are legendary for reliability. The Legacy series (20-80 quart) is the gold standard. Parts are available everywhere. Every repair technician knows Hobart. Price: premium. A 20-quart Hobart is $3,000-4,000.
Globe
Strong competitor to Hobart. Slightly less expensive. Good reliability. The SP series (spiral mixers) is excellent. Good parts availability. Price: 15-20% less than Hobart.
Vollrath
Mid-range option. Good value. The Vollrath Company manufactures in the USA. Decent reliability. Parts are available but less ubiquitous than Hobart. Price: 20-30% less than Hobart.
Univex
Budget-friendly. Italian-made. Good for low-to-medium volume. Parts can be harder to find. Price: 30-40% less than Hobart.
KitchenAid Commercial
The familiar KitchenAid design in a commercial-grade package. 8-quart capacity. Good for very small operations. Not suitable for daily heavy use. Price: $500-800.
New vs Used
When to Buy New
You need warranty coverage. You need NSF certification (required in most jurisdictions). You want the latest safety features (bowl guards, thermal overload protection). You have the budget.
When to Buy Used
Hobart mixers from the 1960s-1980s are legendary. They were built to last 50 years. Many are still running. A used Hobart from this era, in good condition, is often better than a new budget mixer. Price: $800-2,000 for a 20-quart.
What to check when buying used: listen for grinding or whining noises (transmission problems), check that all speeds work, check that the bowl lift mechanism is smooth, check the power cord for damage, check for oil leaks under the mixer, check that the attachment hub turns freely.
Where to Buy Used
Restaurant auctions, restaurant supply stores (refurbished), Craigslist and Facebook Marketplace, bakery closures (contact a restaurant equipment broker).
FAQ
Do I need a spiral mixer or can I use a planetary mixer for bread dough? For occasional bread dough (once or twice a week), a planetary mixer with a dough hook is fine. For daily bread or pizza dough production, a spiral mixer is worth the investment. It mixes faster, develops gluten better, and puts less strain on the motor.
What size mixer do I need for a typical independent restaurant? 20-quart planetary mixer. It handles 90% of restaurant mixing tasks: whipped cream, mashed potatoes, cookie dough, cake batter, compound butter, sauces. If you make pizza or bread dough daily, add a 30-50 pound spiral mixer.
Can I use a 20-quart mixer for small batches? Yes, but there's a minimum. A 20-quart mixer needs at least 2-3 quarts of product to mix properly. Less than that and the attachment doesn't reach the ingredients. For very small batches, keep a 5-quart KitchenAid on hand.
How long does a commercial mixer last? Hobart: 30-50 years with proper maintenance. Globe: 20-30 years. Vollrath: 15-25 years. Univex: 10-20 years. KitchenAid Commercial: 5-10 years with heavy use. The transmission is the most expensive repair ($800-1,500). If the transmission fails on a budget mixer, replace the mixer.
