genio roasters

the double-wall construction insulates the inner drum from direct flame contact, which reduces the amount of conductive heat transferred through the metal and into the beans. this shifts the roast toward convection, where hot air does more of the work. the result is more even heat distribution across the batch and less risk of scorching or tipping, especially in faster roast profiles. single-wall drums can deliver more body and traditional drum character, but they're harder to control in the hands of less experienced roasters. genio's design prioritizes forgiveness and repeatability, which matters if you're dialing in light roasts or training new staff.

genio machines fit roasters who want a modern drum roaster with convection emphasis but aren't ready to move to fluid bed or recirculating systems. the 6 kg model works well for small shops or sample roasting in larger operations. the 15 kg and 30 kg models scale into production roasting for regional roasters. if you're chasing bright, complex profiles and want a drum that won't fight you with excessive conduction, genio is worth a look. they're less common than probat or giesen, so parts and service networks outside of certain regions may be thinner. plan accordingly if you're remote.

genio machines come with profile logging software and gas control, which gives you the baseline tools to record and repeat roasts. the double-wall drum and convection-forward design mean airflow plays a bigger role than on traditional single-wall drums, so you'll need to pay attention to fan settings and exhaust damper position as much as gas input. response time to gas changes is typical for classic drum roasters, slower than direct-fire or hot-air machines but stable once dialed in. the control system is straightforward, not as feature-rich as some higher-end platforms, but functional for roasters who know what they're doing and don't need hand-holding.
