diedrich roasters diedrich ir-1
the IR-1 serves as diedrich's entry point, designed for sample roasting and small batch work rather than production. with a 0.25kg to 1kg batch range and manual controls, it's suited to roasters who need to evaluate multiple coffees daily or run a very small operation. the infrared burner gives you the same heat delivery character as larger diedrich machines, which helps if you're using it to develop profiles for a bigger IR model. build quality matches the rest of the line, with heavy construction that should last decades. the manual-only controls mean you're learning to roast by feel and observation rather than following software profiles. for sample roasting in a larger operation or as a dedicated quality control tool, it makes sense. as your only production roaster, the 1kg maximum gets limiting quickly unless you're selling exclusively at a single farmers market or doing mail subscriptions for a tiny customer base.
what it does well
- same infrared burner technology as production models helps with profile translation
- heavy construction built to last decades in daily sample roasting use
- 0.25kg minimum allows proper evaluation of small sample lots
- holds value well on used market compared to entry-level competitors
where it stops short
- manual controls only with no data logging capability
- 1kg maximum too small for most retail or wholesale production needs
- infrared system has learning curve if this is your first roaster
- price point high compared to other 1kg sample roasters
