genio roasters

genio roasters launched in 2010 out of seoul and has carved out a reputation for double-wall drum designs aimed at convection-dominant heat transfer. founder neil maree, a design engineer, built the line from the ground up with a focus on heat distribution and flavor development rather than pure conduction from a hot drum shell. the company offers a range from 3 kg micro roasters up to 30 kg industrial models, all gas-fired with profile logging control. the aesthetic is cleaner and more colorful than most classic drum machines, which helps them fit into retail spaces. genio positions itself in the specialty market, appealing to roasters who want convection-forward profiles without jumping to full fluid bed or hybrid systems. the double-wall drum construction puts them in the same conversation as other modern drum builders prioritizing gentler bean contact and airflow over direct conductive heat. they're a solid option for small to mid-size roasters who value profile control and want a machine that won't scorch or tip as easily as single-wall designs.
