Coffee Roasting Tech in 2021: Efficiency in Heating and Smoke Mitigation

Roasted Coffee

As the projections associated with climate change become increasingly dire, 2021 saw numerous coffee roasting equipment makers put forth new systems for more efficiently delivering heat to the beans inside a roaster, or for mitigating the smoke that results.

On a separate sustainability front, electric roaster-maker Bellwether partnered with Sustainable Harvest and Heifer International for a “verified living income” model for green coffee prices.

Yet talking strictly machinery and tech-related news in 2021, there were near-infrared, microwave, and horizontal-oriented fluid-bed systems all claimed to break new ground. A new wet-scrubber and a cold plasma injector blazed trails for clearing the air at the exhaust end, with fuel savings and lower emissions claimed in all cases.

There were other exciting developments, as well, including new systems integrations for green coffee management and for roast profiling, as well as a couple new entries into the United States roasting machine market. Below is a look back at the new developments in coffee roasting tech we covered in 2021.

The steel machines feature hydraulic lifts at the base that raise and tilt the entire unit forward to hasten discharge into the cooling tray. This combines with the drum geometry, drum rotation speeds and airflow management to shorten the cooling process, with the broader goal of target temperature precision in finished roasts.
