Spiral Mixers - SFR40

The Prismafood SFR40 is a 40 litre tilt-head spiral mixer rated for 35 kg of dough from a maximum 21.5 kg of flour and 10.75 kg of water. Those two figures matter more than the bowl volume: they are the manufacturer's actual load limit, and overloading the machine or running it at the wrong speed will void the warranty. The bowl turns at 10 rpm against a spiral arm at 120 rpm, and it draws only 1.1 kW from a standard outlet.

Why operators choose the SFR40

• WARNING - overloading or wrong speed VOIDS the warranty — the manufacturer states this plainly and it is the most important line on the page. Stay within 21.5 kg flour / 10.75 kg water and use the correct speed for the dough
• 35 kg dough from 21.5 kg flour — the real capacity figure. A 40 litre bowl does not mean 40 kg of dough - work to the flour weight
• Tilt head — the head tilts back so the bowl can be emptied and the tools cleared without wrestling a 40 litre bowl. On a machine this size that is the feature you use every batch
• Bowl 10 rpm, spiral arm 120 rpm — the classic spiral geometry - a slowly rotating bowl bringing dough to a fast spiral. It develops gluten without the friction heat a planetary mixer generates
• Lift-up safety guard — the guard has to be down for the machine to run - non-negotiable on an exposed spiral
• Stainless bowl, hooks and shaft — the parts in contact with dough are all stainless
• Timer and simple controls — set it and walk away; the controls are deliberately minimal because staff turn over
• Castors — 114 kg on wheels - it moves for cleaning behind and underneath
• 1.1 kW on a standard 10 A outlet — a genuinely modest supply for a 40 litre mixer. No electrical work needed

Specifications

Venue suitability

The SFR40 suits pizzerias, bakeries, and restaurants making their own dough in batches of up to 35 kg. A spiral mixer is the right machine for bread and pizza dough specifically — a planetary mixer will do it but generates more friction heat, which affects the prove.

Installation & delivery

It runs from a standard 10 A power point, so no electrical work is required. At 1.1 kW it draws about 4.6 A, so the electrical side is genuinely simple for a machine this size. At 114 kg it is a multi-person placement — it arrives on castors, so plan a level route and check the 540 x 825 x 935 mm packed size against your doors. Allow clearance behind for the head to tilt back and above for loading. Brief your staff on the load limit: the manufacturer voids the warranty for overloading, so the flour weight needs to be part of your recipe card, not a guess.

Frequently asked questions

Q: What exactly voids the warranty?

The manufacturer states that overloading the machine and/or using the incorrect speed can cause damage and will void the warranty. In practice that means staying within 21.5 kg of flour and 10.75 kg of water per batch, and using the correct speed for the dough you are making. Put the flour weight on your recipe card - this is the single most common way a spiral mixer is damaged.

Q: How much dough will it actually make?

35 kg, from a maximum 21.5 kg of flour and 10.75 kg of water. Do not work from the 40 litre bowl volume - the flour weight is the limit. For reference the manufacturer notes most pizza dough runs around 60 to 65 per cent water depending on the flour and the maker's preference, plus roughly 2 per cent salt, 1 per cent sugar, 1 per cent yeast and 5 per cent oil.

Q: Why a spiral mixer rather than a planetary?

Dough. A spiral turns the bowl slowly against a fast spiral hook, developing gluten with less friction heat than a planetary mixer generates. Heat in dough shortens and complicates the prove. A planetary is the more versatile machine across a menu; a spiral is the better machine for bread and pizza specifically.

Q: What does the tilt head give me?

Access. The head tilts back so you can lift the dough out and clear the tools without working around a fixed head over a 40 litre bowl. On a machine this size you use it every batch.

Q: Does it need special wiring?

No. 1.1 kW at 240 V from a standard 10 A outlet - about 4.6 A of draw. That is unusually modest for a 40 litre mixer.

Q: What warranty does the SFR40 come with?

Covered for 2 years parts and labour. Terms vary by product — see our warranty information page for full details.
