The MCR-20 Coffee Roaster is a fully featured high performance, high production specialty coffee roasting system. 

The MCR-20 is equipped with dedicated high pressure centrifugal blower roaster exhaust and cooling tray fans that allow for simultaneous roasting and cooling. It is fully RoastPATH Automation capable and offers the option of a  pneumatic coffee loader with integrated scale. This system allows a single operator to easily exceed over 1000 lbs of the highest quality finished coffee per day.

The all-digital control system integrates seamlessly with RoastPATH®, including the highly requested Roast Replay feature. During the roast, RoastPATH® 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.

Total control over your fuel, fan and drum speed allows you remarkable flexibility in your batch size. You can easily scale your batch size up or down without sacrificing quality to focus on a special green or small project.

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.

High capacity cooling trays and stirring arms are designed to hold 3 full batches for post-roast blending. High performance cooling fans cool 2nd crack roasts within 4 minutes.

For roastery cafes in California, the MCR-20 is available in an NSF certified configuration for immediate installation anywhere in the state.

PRODUCTIVE CAPACITY

THE MCR-20 CREATES $3379 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.

20kg Dream Machine!

Even though we haven’t taken delivery of our new 20kg Mill City Roaster yet, the experience so far has been absolutely stellar. Angie and the entire team have gone above and beyond to help us plan our space and ensure every detail is set up for success. They’ve been more like trusted partners than just a manufacturer—offering guidance on layout, answering endless questions, and helping us envision how our roastery will operate once everything’s in place.

We recently flew out to Minnesota for a class at Mill City, and Angie took the time to walk us through the roaster’s setup in person. Her step-by-step explanations and practical insights gave us the confidence we need as we look forward to our roaster’s arrival. We can’t wait to get this 20kg machine installed, seasoned, and turning out some amazing coffee for our customers. If you’re in the market for a commercial roaster, we couldn’t recommend Mill City enough!
