2 Kilogram Coffee Roaster, MCR-2D

$14,000.00 USD Sale Save

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.

  • Optional ferrous steel drum made in-house at the MCR manufacturing facility in Minneapolis
  • Choose from three optional layouts using our Quick-Connect kits to arrange components and exhuast -or- request a custom layout
  • Optional UL® NSF (National Food Safety) package.
  • Optional zero emmision electrically heated Reicatio 100 scent elimination

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

Automated Coffee Roasting

An entirely new approach to automation that keeps craft at the center of what you do. Available on all Digital Roasting System coffee roasters via a RoastPATH® software subscription.

Operator Assist Sensor Package

Standard on all roasters with our Digital Roasting System, the Operator Assist features are designed to lower the cognitive load of the operator. Once you have it, you'll never want to be without it.

Advanced Data Logging

Data is key to a modern coffee roasting practice. Knowing what happening inside your drum is at the heart of your internal QC program but also serves to help troubleshoot maintenance issues, evaluate workflow, and better understand your roasting process.

Precision Variable Control

Mill City Roasters was the first in the industry to offer as a standard feature variable fuel, fan, and drum control (we couldn't believe it either) but we've taken it a step further by refining that control for the operator.

Rapid Return Between Batch Protocol

Consistency in your roasting can only be achieved with stability in your roasting machinery. Automatic between batch protocol is standard on all MCR coffee roasters from the MCR-1 and up.

Certifications

Certified machinery is more easily insurable, installable and our coffee roasters are backed by an experienced team to help advocate on your behalf with installers, contractors and permitting officials.

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.


Install & Maintain

  • Designed for benchtop installation.
  • Detachable chaff collector and cooling tray fan for moving components through standard size door openings. Removable hoppers on all models.
  • Quick-Connect Kits available to arrange exhaust for routing to termination outdoors.
  • Removable access doors on both sides for easy access to interior components.
  • Warranty
