2 Kilogram Coffee Roaster, MCR-2D
The MCR-2D roaster is a high-performance studio and lab roaster designed for ultimate thermal stability and precision roast control. As the smallest model with our Digital Roasting System on board, this 2 kilogram capacity roaster is a fully-featured, professional production system in a compact, bench-top model.
The all-digital control system integrates seamlessly with RoastPATH®, including the highly requested Roast Replay feature. During the roast, RoatsPATH® automatically logs BT, ET, IT and DT temperature readings, as well as fuel setting changes, and fan, fuel and drum speed adjustments. Direct drum pressure is also logged as a feedback loop for operator controlled roast airflow changes.
This model includes the Operator Assist System which automatically recovers to production charge temperature settings, starts timers, and triggers the cooling tray fan and stirring arms off/on at discharge from the drum or cooling tray. This system also incorporates position sensors that make it nearly impossible to accidentally discharge green coffee from the drum into a cooling tray filled with roasted coffee.
The MCR-2D is optionally available with UL Sanitation certification necessary to meet NSF requirements for installation in retail food service locations in California.

PRODUCTIVE CAPACITY
THE MCR-2D CREATES $338 PER HOUR
Roasting 4 full batches an hour on an MCR-2D creates over 14 pounds of roasted coffee every hour. This yield is enough roasted coffee to fill more than 18 12-ounce bags. With a retail value of $18 per 12-ounce bag, you can create $338 of retail coffee per hour.

Features
Chassis
- Monolithic, low carbon steel weldment – the heaviest constructed roasters in their class.
- Fully gusseted for dimensional strength and stability.
- Fully coated to prevent corrosion.
- Integrated double-walled roast compartment is heavily insulated which further converts the chassis into a thermal battery – storing heat, rather than wasting it.
- Materials in both the chassis and the roast compartment absorb heat more efficiently and release heat more consistently for increased stability of temperatures during profiling.
- Trapping heat = trapping noise. Ambient drum noise is limited to a whisper quiet 60 decibels making it easier to hear those early outliers before first crack.
Drum
- Double-wall, stainless steel drums standard on every model. The heaviest, most-efficient drum design in the industry.
- Custom Made-in-Minneapolis Ferrous steel drum optional
- Construction accuracy is machine trued to within +/- .025”.
- 3mm air gap between inner and outer drum diffuses heat more evenly throughout inner drum.
- Diffused heat at inner wall eliminates conductive roast defect, even at higher inlet temperatures.
- Dramatically increased thermal efficiency by storing & using heat, rather than quickly releasing.
- “Bomb proof” construction prevents warping due to operator error.
- Every model equipped with quick response, variable drum speed allowing the operator to achieve ideal bean loft and conductive vs. convective ratio. Result is the flexibility to profile batches from 20%-120% of listed drum capacity on most models.
- Advanced drum gap adjustment mechanism is standard on all models two kilogram capacity or greater, making adjustments easier and more precise.
Fuel
- Custom-designed, CSA® Design Certified low loss gas train designed by Mill City Roasters and used exclusively in our roaster line-up.
- Custom burners designed specifically for coffee roasting.
- Burner layout is specific to each model to achieve optimal burner-to-drum relationship.
- Easy access, external shut-off valves on every roaster.
- Built-in temperature limiters to allow for safe operation.
- Built-in safety shut-off on pilot valve.
- Easy on-site conversion from LP to natural gas.
- Digital electronic modulating valve offering greater control for your most challenging profiles in variable batch sizes.
- Fuel adjustments at the push of a button.
Air & Exhaust
- Power-vented dual exhaust system standard on every model with fan placement designed to allow for easy cleaning and maintenance.
- Roaster exhaust fan is high pressure, high output 3-phase VFD speed controlled with linear response curve for more predictable and more precise airflow control and roast profiles repeatability.
- Cooling tray exhaust fan is a dedicated, high-pressure fan providing rapid cooling to stop roast progression once batch is dropped in cooling tray. Dual exhaust system allow for simultaneous roasting and cooling, reducing back-to-back batch times and increasing production to 4+ batches per hour.
- All machines include face-mounted digital drum pressure gauge.
- All models equipped with dedicated, off-board chaff filtering collectors with easy access doors to aid in frequent clearing of chaff and completion of safety checks.
- Optional quick-release venting kits available for every model.
- Fully specified requirements for venting to termination including layout and cap recommendations.
- Fan adjustments at the push of a button.
Safety
- CSA® Design Certified CSA 1.8 for US and Canada, IEC, CE, ROHS.
- CSA/UL certified Honeywell automatic ignition controller
- All UL/CSA certified Delta PLCs and VFDs.
- CSA/UL certified motors, relays, switches, and wiring.
- Optional UL® NSF Certification available on every model.
- Entire contact path of roaster (hopper, loading chute, faceplate, trier, drum, discharge gate, discharge chute, cooling tray cover, cooling tray floor, stirring/mixing arms, cooling tray gate, cooling tray latch, cooling tray gate) all custom fabricated with certified food grade stainless.
- Teflon cooling tray wipers.
- Heavy duty 5mm x 44mm Borosilicate sight glass.
- Food service safe LED light.
- Food safe resin-impregnated trier handle.
- Stirring arms automatically stop when the cooling tray cover is opened.
