Spiralmac Mixer, SV12 Royal Queen, Bianca

Spiralmac 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 12 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 12 operates at 110-310 RPM.
PROFESSIONAL DESIGN & QUALITY
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 84 lbs. Epoxy powder coating over a steel cabinet protects the handsome appearance of your Spiralmac mixer.

FIXED HEAD & REMOVABLE BOWL
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.
HIGH HYDRATION OR HEAVY DOUGHS
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 12. 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 12 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.
SUPER CAPACITY RANGE
The Royal Queen 12 mixes and kneads up to 26.4 lbs. (12kg) of dough at 60% hydration (or more at higher hydration), but also handles batches as small as 7 lbs (3.2kg) at 60% hydration equally as well. In terms of flour capacity, this is 17.6 lbs. (8 kg) down to as little as 4.2 lbs. (2 kg). Capacity of the stainless steel bowl is 16 quarts (17L). To mix and knead dough below 60% hydration, like challah or bagel dough, Spiralmac recommends filling the bowl to only half capacity.

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.

Permanently Lubricated Reduction Gearbox
The SpiralMac mixer is equipped with a permanently-lubricated gearbox with tempered steel helical screw. The primary drive unit is the heart of the mixer’s power transmission system, and this sealed, helical gearbox provides the ultimate in strength, efficiency and long life, maintenance-free operation.
Featuring bronze alloy bearings and a case-hardened helical screw constantly bathed in high performance synthetic oil, this speed-reduction gearbox is the gold standard of power transmission for dough mixers.
FORWARD AND REVERSE MIXING
There are two buttons on the Spiralmac mixer for controlling the direction of both the dough hook and bowl. The down arrow button moves the spiral hook in a downward motion, and the up arrow button moves the hook in an upward motion. The down arrow button can be referred to as the “forward” direction while the up arrow button can be referred to as the “reverse” direction.
Some users incorporate ingredients with the spiral hook turning in an upward motion, to reduce the amount of oxygen incorporated into the ingredients, and then switch to a downward motion to knead the dough. Others users prefer to mix with the hook turning in a downward motion from start to finish.
COLORS
The Spiralmac Royal Queen 12 is available in Bianca White, Rossa Red, and Vintage Silver.
Caster Wheels
The 12kg Spiralmac mixer comes with four non-locking caster wheels. The wheels are easy to install upon delivery, or remove in the future, if desired.

I absolutely love this machine! It has taken my time in the kitchen from hours to an hour! I still get just as much product out, at a fraction of the time! It's such a quiet machine, I am in awe! The bread comes out at a beautiful consistency. I can make big and small batches, and do a bulk fermentation on my sourdough, then stretch and flip, bulk fermentation, stretch and flip, easily, 2-4 times! Love It!!! Definitely recommend!
Overall a great mixer. I made a YouTube video review of it for anyone like me who couldn't find much on this mixer but overall I think this thing should work well for some time to come. Made an amazing dough.
I love this mixer!! I can fill my RackMaster with sourdough in one batch and wash the bowl in the sink all WITHOUT a dedicated outlet!! And it is red:) So cute!
I had never used a spiral mixer before so I can't compare to other spiral mixers but I will never make bread again in my Ankarsrum or KitchenAid. Never had better texture! It makes my large batches and my two loaf batches. I took a chance and am very happy with this machine.
I do not run a micro bakery. I just make a lot of bread for friends and random strangers:) So this is the perfect size for me. This only downside is a quiet high pitch sound that my old ears can hardly hear but my 14 year old really does and finds annoying.
