    Description

    The Kaleido M10 is a 1.2kg-class electric drum coffee roaster built for roasters who've outgrown small-batch machines and want production capacity without commercial-premises electrics. It's the CE-certified M10 variant, independently verified for legal sale in the UK and EU - worth checking for, since not every M10 sold under that name necessarily is.

    It's the largest roaster in Kaleido's range, and the reason it has a devoted following among small roasting businesses is simple: it delivers drum-roaster batch sizes, full curve control and Artisan integration at a price point well below anything comparable — while running off the same socket as your kettle.

    In simple terms: if you're roasting for a market stall, a subscription round, or a farm-shop account, the M10 takes you from "several evenings of roasting" to "done in one afternoon".

    Built for Real Production Use

    Back-to-back roasting, no cool-down breaks
    Owners report multi-hour production sessions, roast after roast, without overheating or drop-off — the single biggest day-to-day difference from Skywalker-class and fluid-bed machines.

    Responsive by design
    The infrared heating reacts almost instantly to adjustments. Experienced owners describe it as "sportscar-like": small changes produce visible results on the curve within seconds.

    A workhorse build
    85% stainless steel construction, 22.5kg on the bench, with a doubled-thickness front panel and airtight three-layer drum design in the current revision.

    Which version do I need?

    • Standard – Roasts entirely from the attached 7" touchscreen running Kaleido's own software. No computer needed. No Artisan connectivity.
    • Pro – No touchscreen. Driven by Artisan on your Windows or Mac laptop via USB , Wifi or Bluetooth. Kaleido's official Artisan sponsorship means it's properly supported, not an unofficial config file someone's shared online. The cheapest way in if you already know you want full control.
    • Dual – Both: touchscreen roasting straight out of the box, and Bluetooth Artisan when you want to go deeper. A nice way to hedge if you're not sure yet how far into profiling you want to go.

    Can't be run from an iPad or iPhone - Artisan needs Windows or Mac, and the Kaleido system lives on the machine's own touchscreen (Standard/Dual only).

    CE Certification: What It Means and Why It Matters

    Is CE marking actually required, or just a nice-to-have?

    It's a legal requirement. Under EU Directive 2014/30/EU (the EMC Directive), electrical equipment sold in the UK and EU must carry CE marking backed by a Declaration of Conformity. It isn't optional, and it isn't something a manufacturer can apply retroactively to a machine that wasn't tested - it's tied to the specific production batch that was actually submitted for testing.

    Does every roaster with the same model name carry it?

    Not necessarily. A machine can be sold under the same model name - M1, M2, M6, M10 - with or without having gone through certification testing, depending on which batch and which seller. The model name alone tells you nothing about compliance status.

    What's actually certified here?

    The different models we sell has been independently tested and verified by SGS-CSTC Standards Technical Services, confirmed compliant with EN IEC 55014-1:2021, EN IEC 55014-2:2021, EN IEC 61000-3-2:2019, and EN 61000-3-3:2013. We can provide the full verification document on request.

    Why does this matter to you as the buyer?

    Selling or importing non-compliant electrical equipment is a legal issue for the seller, not something that falls on you as the customer after the fact - but it's still worth confirming before you buy, especially when comparing prices across retailers. Ask any seller directly for their certification documentation for the specific unit they're shipping, not just the model name.

    Who is the Kaleido M10 best suited for?

    Home roasting businesses: 40–100 bags a month for markets, subscriptions or local shops - the M10's capacity and back-to-back stamina are built for exactly this.

    Upgraders from Skywalker-class and fluid-bed machines: more even development at full batch sizes, no overheating between roasts, and a build-quality jump you feel immediately.

    Cafés roasting for their own bar: enough weekly throughput for a single site, without three-phase power or extraction-system-scale ventilation.

    Sample and development work: down to ~250g batches with full curve logging.

    Choosing your 1kg roaster: Kaleido M10 vs Aillio Bullet range

    Both are outstanding machines - we stock both because they suit different roasters.

    • Choose the Kaleido M10 if: you want maximum batch capacity per pound spent, you're happy driving roasts from a touchscreen or Artisan, and your priority is production throughput. Roughly the R1 V2's price bracket with 1.2kg capacity and included probes and bean deflector.
    • Choose an Aillio Bullet if: you want induction heating, the IBTS infrared bean sensor, the RoasTime/Roast.World ecosystem, onboard physical controls, a 2-year warranty and the strongest resale value in the class. The R2 Pro adds FlowSense, barometric compensation and enhanced cooling for the most demanding profile work.
    • Warranty difference stated plainly: Kaleido carries a 12-month warranty; Aillio Bullets carry 2 years. Our 60-day money-back guarantee applies to both.

      Matthew, Kaleido M10 Pro owner

      I've had this roaster for approaching 3 years of pretty regular use, originally roasting for about 12kg a week and going as heavy as 25kg a week... You can get professional grade roasts out of this highly compact and easy to use machine. It's very safe by comparison to using any gas based roaster and it's pretty energy efficient for what it is, too. Overall, I'm pretty happy with the roaster and I can see it as a very good value way into roasting great coffee.

      Brad - Scorgo Coffee & Roastery

      It's a great piece of machinery... there's not much that I'd change with the roaster if I'm being honest. As long as you have a basic understanding of creating roast profiles and the roasting stages, you can't really mess a roast up.

      Tom Gatehouse, M10 owner

      Honestly I'm pretty pleased with it. I was concerned that moving from gas to electric would mean moving to an unresponsive roaster, but I've been impressed with how quickly it responds to temperature and airflow changes... Chaff collection is really good, and was partly what sold it to me over the Bullet, which sounded a bit of a pain to clean, particularly when back to back roasting. Back to back roasting is good and the machine handles it well and can achieve a good consistency.

    Frequent Questions

    How much coffee can the Kaleido M10 roast at one time?

    The Kaleido M10 roasts between 300g and 1200g of green coffee per batch, with the most consistent production results at 800g–1000g. It also handles sample roasts down to around 250g, making it suitable for everything from cupping-table samples to small-batch commercial production.

    What power supply does the Kaleido M10 need? Does it need a dedicated circuit?

    The 230V Kaleido M10 runs on a standard UK 13A plug socket — no dedicated circuit, electrician, or gas line required. Its 2400W heating system draws around 10.4A at 230V, well within a normal domestic socket. The dedicated 20-amp circuit warnings you may have read on American roasting forums apply only to 110V US units.

    What do I need to operate the Kaleido M10?

    The Kaleido M10 Standard and Dual roast entirely from the machine's attached 7-inch touchscreen - no computer, laptop, or tablet needed. The M10 Pro is controlled by the free Artisan roasting software on a Windows or Mac computer, connected via USB or Bluetooth. No version of the M10 can be controlled from an iPad or iPhone.

    What is the difference between the Kaleido M10 Standard, Pro and Dual?

    The M10 Standard roasts from its built-in 7-inch touchscreen only. The M10 Pro has no touchscreen and is driven entirely by Artisan software on a computer. The M10 Dual offers both: standalone touchscreen roasting plus Artisan connectivity via Bluetooth. All three share the same drum, heating system, and 1.2kg capacity.

    Is the Kaleido M10 compatible with Artisan roasting software?

    Yes —-the Kaleido M10 Pro and Dual both work with Artisan, and Kaleido is an official sponsor of the Artisan project, so support is built in natively rather than through unofficial configuration files. The Standard version does not connect to Artisan.

    Can the Kaleido M10 roast automatically?

    Yes. On the Standard and Dual versions, you can save a roast profile to the built-in SD card and replay it in automatic mode from the touchscreen, reproducing the same curve batch after batch. Artisan (Pro and Dual) provides manual-first control with full curve logging and rate-of-rise data.

    Can the Kaleido M10 roast back-to-back batches?

    Yes - the Kaleido M10 is built for consecutive roasting, and owners report multi-hour production sessions without overheating or performance drop-off. Automatic overheat protection is built in, and the cooling box brings each batch down in 3–5 minutes ready for the next charge.

    Does the Kaleido M10 need ventilation or smoke extraction?

    For regular use, we recommend ducting the M10's 45mm exhaust outlet to a window or through-wall vent using 50mm flexible pipe and a hose clamp. Smoke output is lower than most smaller roasters thanks to the pressurised exhaust design, but any drum roaster at 1kg batch sizes produces meaningful smoke past first crack. Our Smoke Management & Ventilation collection covers everything you need.

    Do I need to do seasoning roasts on a new Kaleido M10?

    Yes - like all new drum roasters, the M10 needs around three seasoning roasts of approximately 600g of inexpensive green coffee, which should be discarded. This burns off manufacturing residues and coats the drum before you roast coffee to drink or sell.

    Kaleido M10 vs Aillio Bullet — which should I buy?

    Choose the Kaleido M10 for maximum batch capacity per pound spent: 1.2kg drum roasting with Artisan support from a standard UK socket. Choose an Aillio Bullet for induction heating, the IBTS infrared bean sensor, the RoasTime and Roast.World ecosystem, onboard physical controls, and a 2-year warranty. We stock both ranges and are happy to talk your decision through - arrange a call.

    Is the Kaleido M10 good for a small coffee roasting business?

    Yes — the Kaleido M10 is one of the most popular roasters for home-based coffee businesses roasting 40–100 bags a month for markets, subscriptions, and local shops. Its 1.2kg capacity, back-to-back stamina, and repeatable automatic profiles cover a week's production in a single afternoon.

    What warranty does the Kaleido M10 come with?

    The Kaleido M10 comes with a 12-month warranty, backed by our 60-day money-back guarantee: if you're not happy, we'll arrange collection and a full refund.

    Is the Kaleido M10 CE certified?

    Yes - every M10 we sell is the CE-certified M10-C variant, verified by SGS-CSTC Standards Technical Services (Verification No. GZEM2407004105HSV, 29 January 2026), confirmed compliant with EN IEC 55014-1:2021, EN IEC 55014-2:2021, EN IEC 61000-3-2:2019+A1:2021+A2:2024, and EN 61000-3-3:2013+A1:2019+A2:2021 under EU Directive 2014/30/EU. We don't stock or sell an uncertified unit of any Kaleido model.

    Why does CE certification matter when comparing roasters?

    It's a legal requirement for electrical equipment sold in the UK and EU, not a marketing add-on. Certification applies to specific manufacturer batches, so it's not something you can assume is present just because two listings use the same model name. If price is the main thing you're comparing, ask the seller directly for their certification documentation before you buy.
