Brullen i91 Pro Soft Serve Machine Gravity Feed Non-Pasteurise I91PRO_NP-GF

The Brullen i91 Pro is a single-flavour countertop soft serve machine with a 12 litre mix tank, rated at 250 to 500 serves per hour. This is the gravity-feed build, running 15% to 45% overrun for a denser, gelato-style product. It runs from a 15 A dedicated circuit — note dedicated: it should not share with other equipment.

Why operators choose the I91PRO_NP-GF

• A 15 A dedicated circuit — the word that matters is dedicated. A soft serve machine cycles its compressor hard and continuously; sharing a circuit with other kitchen equipment is how you get nuisance tripping during service
• Countertop at 115 kg — it sits on a bench rather than the floor, but 115 kg is a serious weight for a counter - check what the bench is rated to carry before ordering
• Gravity feed: 15% to 45% overrun — overrun is how much air is whipped into the mix, and it is the number that decides both texture and yield. A gravity-feed machine relies on the mix falling into the cylinder, which limits how much air goes in - so you get a denser, more gelato-like product and fewer serves per litre
• Soft-touch operator menu — the controls a staff member actually uses, on a sealed panel that survives a sticky bench
• POM plastic scraper blades — the blades scrape the frozen layer off the cylinder wall. Plastic rather than steel means they wear instead of the cylinder
• R404a refrigerant, air-cooled condenser — no plumbing for the condenser - but it does need airflow around it

Specifications

Venue suitability

The i91 Pro suits cafes, dessert bars and takeaway venues adding soft serve to an existing counter. Single flavour and 250-500 serves an hour is a genuine working machine rather than a novelty, and the gravity-feed build gives the denser product if that is the style you want.

Installation & delivery

A 15 A dedicated circuit is required. Dedicated is the operative word — the compressor cycles hard and sharing the circuit invites nuisance tripping mid-service. Dimensions are recorded width x depth x height: 400 x 750 x 840 mm, weighing 115 kg (130 kg crated). That is heavy for a countertop machine, so confirm the bench is rated for it. The air-cooled condenser needs clear airflow — do not push it back against a wall or into a recess.

Frequently asked questions

Q: What is overrun, and why does it matter more than anything else here?

Overrun is the percentage of air whipped into the mix. It sets both the texture and your yield. A gravity-feed machine runs 15-45% overrun and gives a denser, gelato-like product; an air-pump machine runs 40-80% and gives classic light soft serve. The commercial consequence is the yield: at 80% overrun one litre of mix becomes roughly 1.8 litres of finished product, where at 20% it becomes 1.2. If you are comparing a gravity-feed and an air-pump version of the same machine, that is the difference you are actually choosing between.

Q: What electrical supply does it need?

A 15 amp dedicated circuit. The 'dedicated' part matters more than the amperage: a soft serve machine's compressor cycles continuously through service, and sharing the circuit with other equipment is how you get a breaker tripping in the middle of a rush.

Q: How does the Pro differ from the standard i91?

Capacity and size. The i91 Pro does 250-500 serves an hour and weighs 115 kg in a 400 x 750 x 840 mm cabinet; the standard i91 does 210-425 serves an hour, weighs 105 kg and is narrower at 324 mm but slightly deeper and taller. Both are single-flavour countertop machines with a 12 litre tank and the same 15 A dedicated circuit.

Q: Is 115 kg really a countertop machine?

It is designed to sit on a bench rather than the floor, but 115 kg concentrated on a small footprint is a lot. Check what your counter is rated to carry, and plan how it gets up there - this is not a two-person lift onto a bench without equipment.

Q: Does it need plumbing or extra ventilation?

The condenser is air-cooled, so there is no water connection for cooling - but it does need clear airflow around it, and boxing it into a tight cabinet will cost you capacity on a hot day. Our data does not record a ventilation clearance figure for this model, so check the equipment manual or ask us before you build it into joinery.

Q: What is the scraper blade made of and why does that matter?

POM plastic. The blades scrape the frozen layer off the inside of the freezing cylinder thousands of times a day, and the choice of material decides what wears out. Plastic blades wear instead of the cylinder, so the consumable is a cheap replaceable part rather than the machine itself.
