Univex SRM20+ 20 Qt Planetary Mixer, Countertop, 1/2 HP, 115V

The Univex SRM20+ is a 20-quart countertop planetary mixer driven by a 1/2 hp capacitor-start motor on a 115 V supply at 10.6 amps. It is the largest bowl Univex puts on a counter, and its speed range is markedly wider than the 12-quart machine’s — 135 rpm at the bottom, 528 at the top.

A wider spread than the smaller mixer, and why that is the point

Univex marks this beater shaft at 135, 260, 435 and 528 rpm. Compare the SRM12+, which runs 152 to 406: this machine goes both slower at the bottom and considerably faster at the top. The slow end is where a 20-quart batch of bread dough wants to be started, and the fast end is where egg whites and cream come up quickest. Having both in one mixer is what lets a 20-quart bowl cover a whole day’s production rather than one job in it.

As on every SRM, the four marked positions are reference points rather than stops. Torque-sensing variable-speed pulleys working through hardened alloy gearing hold any speed across the range, and the speed is adjustable while the machine runs — so a dough can be brought up gradually as the flour hydrates instead of being jolted a gear at a time.

The power take-off runs slow on this model, deliberately

If the optional #12 hub is specified, its speeds are 62, 133, 198 and 238 rpm — substantially slower than the 117 to 316 rpm of the 12-quart machine, even though the mixer itself is faster. That is not a contradiction: grinding and shredding attachments work best at low shaft speeds, where they cut rather than smear, and a slower hub on a stronger motor is the better arrangement for meat. Order the hub with the machine; it is a build option rather than a later addition.

Why Operators Choose It

• The biggest bowl on a counter. 20 qt. (18.9 L) stainless steel, supplied as standard equipment.
• 135 to 528 rpm. A wider spread than the SRM12+ at both ends — slower for dough, faster for aeration.
• Change speed under load. Variable-speed pulleys and hardened alloy gearing, adjustable while running.
• Still a 115 V machine. 10.6 A on a NEMA 5-15P plug with a 6 ft attached cord; 208–240 V available at 4.8–5.3 A.
• Twice interlocked. The machine stops if the guard is opened or the bowl is lowered.
• Two-year on-site warranty. Univex’s term across the planetary range.

Controls

Momentary-contact start and stop through a contactor, with a self-locking hand crank raising and lowering the bowl. The 15-minute timer is listed as an option.

Ideal For

Bakeries and pizzerias mixing their own dough, pastry kitchens, restaurant and hotel kitchens, delis and sandwich shops making fillings in quantity, and operations that need 20 quarts without giving up floor space.

Specifications

Why the dimensions look wrong

They look wrong because they are a crate, not a mixer. Univex gives 41" × 33" × 22" with the pallet included, and prints the same three numbers for the smaller SRM12+ — which cannot both be the machine. No machine-only dimension is published for either. Plan a bench or a doorway from a figure we get confirmed for you, not from the crate.

Dough capacity

Univex publishes no dough-capacity figure for this model on its specification sheet. A capacity chart does exist in the company’s brochure and in the operator manuals, with conditions attached — flour moisture, water temperature, absorption ratio and in some cases a speed restriction — but the tables do not extract cleanly enough for us to be certain which figure belongs to which model. We would rather tell you that than print a pounds-of-dough number that might be the next model’s. Tell us the dough and we will get the figure confirmed by Univex before you order.

Certification

Be precise about this one, because it is easy to overstate. Univex’s NSF wording attaches to the finish: the sheet describes a durable NSF-approved hybrid epoxy / polyester powder coat. It is not a statement that the machine is NSF listed, and Univex publishes no cETLus, UL or ETL mark for any SRM planetary mixer. The "CSA and UL approved" note in the operator manuals refers to the wire insulation in the harness, not to a listing of the mixer. We have quoted the finish claim and left the rest alone.

Bowl size, page against sheet

Univex’s web page for this mixer offers a 22 qt. stainless bowl where the specification sheet rates the machine at 20 qt., and the page prints 120/60/1 against the sheet’s 115 V. Both figures above come from the sheet. A bowl bigger than the rated capacity is not extra capacity and we do not list it as such.

What’s Included

• 20 qt. stainless steel bowl
• Two-piece stainless steel safety guard
• Self-locking hand crank bowl lift

Factory Options and Accessories (Additional Cost)

• ALMFC12 meat and food grinder for the #12 hub
• VS9 vegetable slicer with adjustable knife
• VS9H vegetable shredder with plate holder and 3/16" plate, with further plate sizes, grater plates and a julienne plate available
• #12 power take-off hub, where not already fitted
• 15 minute timer

Warranty

Two years, on-site parts and labor. Univex states the term in each model’s operator manual — the mixer "carries a two-Year, on-site, parts and labor warranty against any defects in materials or workmanship" — and in its Planetary Mixer Selection Guide, which applies it to every planetary mixer the company builds. Warranty work is scheduled 8:00 am to 5:00 pm local time, Monday to Friday, and claims go to the Univex Warranty Service Department before any repair. Overloading the mixer beyond the published capacity voids it.
