petroncini

Petroncini has been building drum roasters in Ferrara, Italy since 1919. by the 1930s, roughly 80% of italian roasters were using their machines, which built a reputation around forged cast iron construction and consistent heat transfer. the company became part of IMA Group and still manufactures both small-batch specialty machines and large industrial roasters up to 120 kg. their drums use cast iron flywheels and ferritic steel walls, materials chosen for thermal stability rather than cost savings. the TT series focuses on manual control with profile logging, giving experienced roasters direct influence over convection and conduction balance through adjustable heat, airflow, and drum speed. the TMR line adds full automation for production roasting. Petroncini machines appeal to roasters who want heavy-duty construction and the ability to shape thermal curves without fighting the equipment. they're not entry-level machines, and the control philosophy assumes you already know what you're trying to do with a roast profile. expect these to show up in established specialty shops and mid-size production facilities where longevity and repeatability matter more than touchscreen interfaces.
