Spiralmac Royal Queen 5 Spiral Dough Mixer

Challah breadSpiralmac spiral dough mixers are built in Italy by a family-run company that’s made quality food preparation equipment since 1964. The Spiralmac Royal Queen 5 mixer is a dough expert, designed expressly to mix and knead doughs, from low to high hydration, quickly yet gently. The key feature that makes this possible is the spiral dough hook, working in combination with the dough breaker bar.

The Spiralmac’s bowl itself rotates, bringing the dough to the spinning spiral dough hook with each revolution. This action is exceptionally thorough and uniform. An integrated offset breaker bar ensures ideal metering of the dough into the spiral hook. This three-way kneading process is exceptionally thorough and fast, yet the low impact and widely distributed dough contact of the spiral hook completely avoids overworking and overheating of the dough. Wide-range, infinitely variable speed adjustment lets you dial in precisely the action you want. The spiral dough hook on the Spiralmac Royal Queen 5 operates at 110-310 RPM.


Spiralmac mixers feature heavy duty chain overhead drive for the dough hook. The lower (bowl) drive is driven by a sealed, speed reduction gearbox and heavy duty chain. Sealed industrial ball bearings are used for exceptionally long life. Construction is robust throughout, with a weight of 59 lbs. Epoxy powder coating over a steel cabinet protects the handsome appearance of your Spiralmac mixer.

Variety of breads


The Spiralmac mixer features a clever design that provides a removable bowl while avoiding the complexity involved with a tilting head. Both the breaker bar and the dough hook are removable, coming off in just twenty seconds, without tools, simply by loosening two large knurled knobs. This simple and ingenious design features fewer moving parts in the drive train for low maintenance and quiet, trouble-free operation. It also allows you to take the dough hook and breaker bar to the sink for quick, easy cleanup. The bowl can be lifted out with dough—or, to divide the weight, the dough ball can be removed first, followed by the empty bowl.


Thanks to the spiral hook’s action, mixtures that overtax other designs—such as pizza or bagel dough—are handled easily, quickly and efficiently in the Spiralmac Royal Queen 5. Doughs of all kinds, from heavy to high-hydration artisan doughs, come out smooth, silky and perfectly developed. With its wide speed range, the Royal Queen 5 handles the full range of dough densities. Read more about which speeds to run the mixer at based on hydration level in the "Speed Based on Hydration" paragraph below. Click here for the approximate RPM at each speed. 


The Royal Queen 5 mixes and kneads up to 11 lbs. (5kg) of dough at 60% hydration (or more at higher hydration), but also handles batches as small as 1.1 lbs (0.5 kg) at 60% hydration equally as well. In terms of flour capacity, this is 4.4 lbs (2 kg) down to 0.44 lb (0.2 kg). Capacity of the stainless steel bowl is 7.4 quarts (7L). To mix and knead dough below 60% hydration, like challah or bagel dough, Spiralmac recommends filling the bowl to only half capacity. 

  1. Heavier doughs can be mixed when the hydration level is higher than the 60% hydration formulas listed above.
  2. The flour used for these capacity tests was 00 durum wheat flour.

Speed Based on Hydration

The Spiralmac is a variable speed mixer that has a speed dial marked from 0-10. The table below shows the maximum speed Spiralmac recommends for mixing dough at different hydration levels. These are general guidelines, as dough characteristics vary. If mixing dough that's less than 60% hydration, Spiralmac recommends only filling the bowl to 50% capacity, and mixing for only 10 minutes at a time; judgment must be exercised in any case, to avoid kneading dough so dry it’s outside of normal baking parameters, regardless of the hydration numbers. With dough over 60% hydration, dough can be mixed for up to 20-25 minutes before the mixer should be turned off for about 40 minutes.
