Hearthware has discontinued the original I-Roast model Coffee Roaster, please see the new and improved I-Roast 2!
As seen in
Hearthware went to painstaking measures to ensure this unit was ready for the home roasting market. The I-Roast has many built-in features that have been sought after by home roasting novices & enthusiasts alike. Read further to know about some of these features.
The units come equipped with two factory programmed presets, allowing slightly varying roast curves giving you the choice of which you prefer. In addition to the pre-slect roasting curves, the I-Roast also allows complete 3-stage programming in which you have the flexibility to control temperature, and time in all three stages of roast. Find a bean that you like a roasted a certain way? Program the curve, and use that curve again, and again for consitent roast batches. No other home coffee roaster has ever packed this much umph into a home coffee roasting unit!
The heavy-duty motor has two RPM speeds, which it automatically oscillates between during its cycle. The pattern of the airflow, which is a patented design, gives the flow of beans a "fountain" action when the unit kicks in to its higher RPM 2nd speed. This serves both to displace the hotter beans that are floating in the "roast column", so the cooler beans that are floating outside of the "roast column" can enter and have their chance to roast a bit hotter, and to help maintain a consistent chamber temperature. Based on internal temperatures, the unit "shifts" gears to the higher RPM, and maintains the higher RPM until the units senses the units internal temperature is getting to low, then once again, shifts into low RPM stage & starts the heat process all over, throughout the duration of the roast cycle..IRoast manufacturer preset roast cycles: Stage 1Stage 2Stage 3Preset 1:385° 3 minutes425 4 minutes455 2 minutesPreset 2:455 6 minutes400 4 minutes435 1:30 minutesOn these new units, the roast profile and characteristics has been modified slighlty from the 1st production I-Roast units. Now, instead of the machine regulating the high & low motor speeds based upon time, the units motor shifting is based upon internal temperature of the unit. Controlling the roast in this manner allows for a much more even internal temperature, and also allows the temperature read out to be closer to actual programmed temperatures. Upper and lower tolerances in the internal roast temperature are also much tighter. Also, on the newer units, the nusance of the unit not powering on properly in colder temperatures - due to an errant self-check phase has also been eliminated, allowing for consistent operation.Roasting you own coffee is both enjoyable, and provides you with the freshest cup of coffee you can get... you really will be astounded by the difference it makes in the quality of your cup!
