1 Kilogram Coffee Roaster, MCR-1
The MCR-1 is designed as a high-quality production system for small coffee roasteries worldwide. Featuring the same monolithic weldment plate steel chassis and drum construction as our largest production roasters, this 1 kilogram capacity coffee roaster is a great solution to the aspiring professional roaster looking for a solid foundation from which to launch a coffee roasting business.
This model is RoastPATH® connectable with an integrated USB port that passes BT, ET, and DT thermocouple readings along with input changes in fan speed and resultant digital drum pressure. The roaster is equipped with variable drum speed for optimal roasting from batch sizes from 200 to 1200+ grams. Control on this machine is via hand adjustments of the gas input and power input for the fan and drum speed.
The MCR-1 features a thermally isolated cooling tray and high output cooling tray fan that cools coffee from 2nd crack in as little as 4 minutes.
The MCR-1 is available in an NSF certified configuration.

PRODUCTIVE CAPACITY
THE MCR-1 CREATES $169 PER HOUR
Roasting 4 full batches an hour on an MCR-1 creates over 7 pounds of roasted coffee every hour. This yield is enough roasted coffee to fill more than 9 12-ounce bags. With a retail value of $18 per 12-ounce bag, you can create $169 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.
- 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.
- High precision CV needle valves.
- Precision analog gas gauge.
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.
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.
Install & Maintain
- Integrated chaff collector.
- Removable hoppers on all models.
- Quick-Connect Kits available to quickly connect components and arrange exhaust for routing to termination outdoors.

Planning & Installation
Gas
Operates on LP gas or natural gas. Requires commercial gas pressure via 1/2" NPT connection. See installation manual for detailed pressure requirements.
Burners arrive configured for LP gas but can be converted for natural gas using our easy, on-site conversion kit.
We can also help sourcing the correct gas regulator for your installation and talk your installer through any questions they have regarding gas pressure.
Electricity
Requires a dedicated single phase circuit, 220-230V, 15A, 50-60Hz.
Unit arrives with a power cord measuring 3 feet (1 meters) terminated with a NEMA 6-15 plug.
Venting
Requires dedicated Category III, Positive Pressure exhaust line(s) to carry exhaust from roaster drum & cooling tray to termination outdoors.
See installation manual for maximum runs, minimum heat ratings and clearance-to-combustible requirements. Our Design Team offers free consult to help you make a plan for your building.
