    Commercial coffee roasters: used, refurbished, and trade-ins.

    Posted on July 25, 2022 at 8:07 am by / 0
    ​​Most of you know that, beyond the occasional swapped out demo machine, we do not normally deal in used or refurbished coffee roasters. Our machines are proven to hold their value. For us however, reselling used coffee roasting machines sight unseen and then arranging local crating and transportation require steeply discounted prices to cover these… Read More

    Why does the weigh/fill machine need compressed air?

    Posted on June 27, 2022 at 2:27 pm by / 0
    I received a very good question from a prospective weigh/fill customer today about why our weigh/fill machine needs an air connection and others do not. This was my response: Strictly speaking, an air connection is not mandatory. If you have one though, you’ll fill bags about 30% faster. Roasting coffee isn’t necessarily all about speed,… Read More

    The “Perfect” Roaster?

    Posted on June 24, 2022 at 3:44 pm by / 0
    A funny thing happened the other day on Facebook Coffee Roasters Forum. Another numbskull posted that his company was engaged in the exercise of building the “perfect” roaster and asked people to chime in about what they thought their “dream roaster” would look like. I have several problems with this entire exercise. First, if your commercial… Read More

    Best Commercial Coffee Roaster: the myth of the “perfect” roaster.

    Posted on April 26, 2022 at 1:40 pm by / 0
    I’ve been hanging around commercial coffee for awhile and I don’t normally search the internet for the “best commercial coffee roaster”. Recently though. I’ve been inundated with spam and internet ads and breathless paid placement new product release articles and a proliferation of weaponized click bait sites. I can only imagine that the marketing departments… Read More

    BTU per pound? Scaling from a small to a large production coffee roaster?

    Posted on March 9, 2022 at 3:43 pm by / 0
    I received an email from a customer this morning with a good question about BTUs:   “I am seeking a roaster that can do somewhere in the range of 20-25 pound batches at 12 or so minutes. we are on an 8 pound roaster now and we can get 8pounds to FC at between 8-9min… Read More

    “Why is there a cover over the cooling tray?”

    Posted on February 4, 2022 at 9:56 am by / 0
    That’s a good question. We incorporate cooling tray covers because our cooling trays are very much higher performance than industry standard. They are designed to cool a full batch of coffee from second crack within 4 minutes and they are designed to accommodate 3 full batch sizes for blending roasted coffee. That means we use… Read More

    MCR 30kg vs Diedrich DR25 coffee roaster?

    Posted on January 19, 2022 at 5:08 pm by / 0
    I received an email today from a customer asking how our MCR 30kg compares to Diedrich DR25. Although I have a great deal of familiarity with the Diedrich’s IR and CR series roasters, I was unfamiliar enough with the DR model that I was forced to review Diedrich’s website and study the specs. This is… Read More

For years, Mill City Roasters pioneered and championed the use of Artisan and Cropster for several years even going so far as to contribute to the Artisan build library and provided Phidget… Read More

    Is Mill City Roasters a Chinese brand?

    Posted on May 4, 2020 at 2:17 pm by / 0
    Comment from What’s the Best Coffee Roaster? on Youtube: holly1 day ago Thanks for your input, it is still an opinon from a chinese brand whose competitive advantage was price. But you got a few points clear, there’s market paranoia and some brands are cutting corners somewhere and pressing with bulls** arguments. I’m shure this… Read More

    How do our large roasters compare?

    Posted on September 10, 2017 at 7:28 am by / 0
    Ridiculous. Our machines are constructed as solid plate steel weldments. They are heavier and quieter than almost everything on the market, and just happen to be robust and powerful enough to profile roast full batch sizes for as long as you care to stand there. The only people talking about continuous use or vibration problems… Read More
