IR-12
The IR-12 is the biggest machine in our IR-Series. Using our innovative infrared technology, it can handle everything from half a pound to 12 kilograms (26.4 pounds) with complete precision. Like all our roasters, the IR-12 can significantly save energy and reduce the amount of harmful gas exposure to your coffee.
With a full batch roast time of 13-16 minutes, you can roast up to 105 pounds per hour. We wouldn’t recommend drinking all of that in one sitting, though. For the most flexibility, from boutique batches to big orders, check out the IR-12.
