Kaleido M6/M6S Coffee Roaster

Product Overview & Selection

Summary

KALEIDO M6/M6S Sniper Coffee RoasterDesigned for experienced home roasters, small coffee studios and cafés working in small batches. The recommended batch size is 200–600g, with a maximum capacity of 700g. Carbon-fibre infrared heating works with recirculating hot air, while dual temperature probes, a perforated drum, side-mounted trier, quartz viewing window, automatic chaff collection, built-in smoke exhaust and a separate cooling system support the roasting workflow.

Choose the Smart, Artisan or Dual version to suit your workflow. During a roast you can monitor bean temperature, environmental temperature and ROR, mark key events, and adjust heat, airflow and drum speed to build, compare and repeat roast profiles for different coffees.

Product Information

，

The M6/M6S sits between the M2 and M10, offering more than a larger maximum batch of 700g. It retains roast-profile monitoring, physical sampling and control over key parameters for users who need greater capacity. Suitable uses include sample and cupping roasts, specialty-coffee trials, roasting classes, recipe development and small-batch in-house roasting for cafés.

The manufacturer's hardware manual gives a reference throughput of up to approximately 2.5kg of green coffee per hour. Actual output depends on preheating, batch size, roast level, profile length, cooling and cleaning between batches, so this figure is not a guaranteed production rate.

KALEIDO M6／M6S coffee roaster KALEIDO M6 M6S

• Recommended batch size: 200–600gSuitable for experienced home roasters, studios, roasting classes, sample evaluation and small-batch café use; maximum capacity 700g.
• Carbon-fibre infrared heating with recirculating hot air:Infrared heating provides a responsive electric heat source, while recirculating hot air helps transfer heat to the coffee and manage exhaust.
• 304 stainless-steel perforated drum:The perforations expose the coffee to infrared heat and circulating hot air while allowing loosened chaff to fall into the collector below.
• Heat, airflow and drum-speed control:Adjust the main parameters for the coffee variety, processing method, batch size and target roast profile.
• Adjustable dual temperature probes:Monitors bean temperature and environmental temperature. Probe depth can be adjusted, and the selected control system displays ROR and profile changes.
• Charging hopper and rotary gate:Once preheating is complete, open the gate to charge the green coffee.
• Side-mounted trier and viewing window:Draw a small sample during roasting, then use the sample light and quartz viewing window to assess colour and roast development.
• Automatic chaff collection:Chaff collects in a drawer for straightforward inspection and cleaning after each roast.
• Independent dual fan cooling:The cooling tray draws heat away from several directions to slow further roast development after discharge. Public information for different versions gives an approximate reference cooling time of 2–5 minutes.
• Built-in smoke exhaust structure:An internal fan and exhaust path direct smoke towards the outlet. Coffee roasting still produces smoke and odour, so adequate ventilation and a suitable exhaust arrangement are required.

Save the completed roast profile and batch notes. On a later roast, load the saved profile as a visual reference for manual tracking or use the applicable automatic mode for temperature or heat tracking.

Product Details

In the applicable automatic modes, the roaster can still adjust heat, damper and drum/agitation settings to respond to the coffee and conditions while using the saved profile as a reference.

Product Details

1. Pre-use checks:Check the power supply, plugs, ventilation and exhaust, and ensure that the chaff drawers, cooling plate and sampler are installed correctly.
2. Preheat:Start the drum and airflow, set the preheat temperature and begin heating.
3. Charge the beans:When the target preheat temperature is reached, mark the charge event in the control interface, then open the charging gate.
4. Manage the roast profile:Adjust the heat, airflow and drum speed according to the bean temperature, ambient temperature and ROR.
5. Observe and mark events:Use the trier, viewing window and event markers to record turning point, first crack, second crack and other important stages.
6. Discharge and cool:At the target development point, discharge the coffee, stop heating and start the separate cooling system.
7. Save the record:Save the completed profile and batch notes for later comparison, adjustment or repetition.
8. Clean:Inspect and clean the chaff drawers after each batch; further cleaning should be done only after the machine has cooled.

Who It Suits

• Experienced home roasters:Users upgrading from a smaller roaster to a maximum capacity of 700g.
• Coffee studios and roasting classes:Users who need to record profiles, compare settings and run repeat trials.
• Small coffee shops:Small-batch roasting, limited coffees, recipe testing or cupping preparation.
• Artisan users:Choose the appropriate version to record and analyse roast data in Artisan.

M1、M2、M6 choose？ M1 M2 M6

For more practice batches from a smaller amount of green coffee, M1 or M2 offers greater flexibility. If you regularly roast around half a kilogram or want fewer repeat batches of the same recipe, the capacity of M6/M6S is likely the better fit.

Frequently Asked Questions

KALEIDO M6／M6S suitable for？ KALEIDO M6 M6S

The Smart version's integrated touchscreen makes it easier to establish a roasting workflow. The M6/M6S still handles larger batches and offers several adjustable parameters, so users should first understand basic roast stages, ventilation, exhaust and safe operation.

YesCoffee Beans？

The recommended batch size is 200–600g, with a maximum capacity of 700g. Green-coffee density and moisture, ambient conditions and the target profile all affect performance; for consistent batches, do not treat the maximum capacity as the default daily batch size.

Yes？

The manufacturer's hardware manual lists a reference maximum of approximately 2.5kg of green coffee per hour; this is not a fixed production rate. Actual throughput depends on batch size, preheating, roast level, profile length, cooling, exhaust and cleaning between batches.

Yes？

The applicable Kaleido system displays bean temperature, environmental temperature and ROR; marks charge, turning point, first crack, second crack and discharge; and saves or loads earlier profiles. Depending on version, automatic profile mode can track temperature or heat while still allowing manual adjustment of key parameters.

Supported Artisan ？ Artisan

The Artisan version (Pro) and the dual-system version (Dual) provide Artisan workflow; the smart version mainly uses the Kaleido system. Connection methods, compatible devices and software requirements will vary with control board version and should be checked before purchase.

Pro Dual ？ Pro Dual

Pro is centred on an Artisan workflow. Dual retains both the Kaleido touchscreen system and Artisan support. Choose Pro if you only need Artisan; consider Dual if you want touchscreen operation and both workflows.

？

No. The built-in exhaust helps direct smoke to one outlet, but roasting still produces smoke, odour and chaff. Use the roaster in a well-ventilated location with extraction appropriate to the batch size and installation.

Coffee Beans？

Public information for different M6/M6S versions gives reference cooling times of approximately 2–5 minutes. Actual cooling depends on batch size, room temperature, tray airflow and cleanliness.

？

Public reference figures for different versions are approximately 4–15 minutes. Coffee, batch size, preheating, target roast level and profile design all affect the time, so doneness should not be judged by minutes alone.

Yes？

Because cooling operates separately, you can prepare the roaster for the next batch while discharged coffee cools. Follow the manual and account for electrical supply, exhaust, machine temperature and cleaning between batches.

？

Check and clean the chaff drawer after every batch. Once the machine has fully cooled and is disconnected from power, remove fine chaff, dust, flat beans and fragments from the drum. Do not open the machine while it is powered or hot.

Yes？

Installation and assembly can vary by region, shipping method and production batch; some versions may require heater installation or controller connection. Before first use, inspect, install and verify the power supply according to the manual supplied with the unit. Do not rely on installation videos for a different version.

？

Controllers, connection cables, exhaust accessories, plugs and other included items may vary by Smart, Pro or Dual configuration, control board and production batch. Refer to the packing list for the selected SKU; accessory sets shown for other regions are not guaranteed to match.

Home use is possible where there is sufficient space, ventilation, suitable extraction and an appropriate electrical supply. Before purchase and installation, check voltage, power, plug and circuit load against the machine's rating plate. If unsure, consult a licensed electrician.

Product Details

• Before use, read the manual for the version supplied and check the rating plate, voltage, power and plug.
• Operate in a well-ventilated area away from flammable materials. Do not block the exhaust outlet or assume that the built-in exhaust makes roasting smoke-free.
• Do not leave the roaster unattended. The hardware manual says not to set bean temperature above 230°C; this is a safety limit, not a recommended roast endpoint.
• Continue cooling after discharge. The hardware manual says to keep the relevant system running until the coffee falls below 50°C; follow the instructions for the version supplied.
• Inspect and clean the chaff collector after every roast. Do not touch or disassemble the machine while it is hot.
• The body, drum and exhaust outlet become hot during use. Leave the safety clearances specified in the manual for the installation.
