Leading legacy IMA COFFEE PETRONCINI ON HOW THE ROASTER MANUFACTURER HAS STAYED AHEAD OF THE CURVE FOR MORE THAN A CENTURY.
Petroncini has been a leading force in coffee roaster manufacturing for more than a century.

ince Ruggero Petroncini founded the company in 1919, Petroncini has become globally renowned for its quality manufacturing of roasters, using a cast iron material that has become synonymous with the Italian manufacturer. The company grew to offer complete coffee plant solutions, encompassing green bean coffee intake, fully automatic roasting, storage and degassing systems, and joining with IMA Coffee in 2018 extended the reach of Petroncini even further. “We continue to innovate in our field and are always developing our roaster engineering and design to reach the highest productive efficiency,” says Maurizio Mazzoni, IMA Coffee Petroncini R&D Manager. Research and development have been a core pillar of Petroncini since its founding. Mazzoni says the company’s many milestones have kept the choice of materials used and its improved product engineering front and centre. This is evident in the roaster’s TT Traditional Roasters range. “The innovation applied to these machines over the years has in no way affected the quality of the materials and the robustness of the original product, but instead has set out to put the master roaster at the centre of the process.” Thanks to heat control, roasting air volume and the drum rotation speed, Petroncini TT Model allows the operator to vary their method of transferring heat to the bean, achieving a perfect balance between convection and conduction. “We are always saying that creativity in personalising the product is in the hands of the roaster, and we want to provide all the tools capable of turning that creativity into reality,” Mazzoni says.

“We can thus succeed in achieving countless sensory profiles, developing the coffee’s deepest aromas, from light roasting to the very darkest.” The TT Specialty Roasters can roast up to 80 kilograms per hour and are suitable for specialty coffee roasteries, coffee shops, or pilot plant machines. For more medium-sized businesses, Mazzoni recommends the larger TTA models. “Ranging from 240 up to 1600 kilograms per hour capacity, TTA Roasters allow the roaster to meet a wide range of customer requirements,” he says. “TTA Roasters facilitate coffee with a dense and rich aroma. The air convection technology allows a perfect coffee roasting control, optimising the thermal efficiency and the flavour development.” The TTA roasting chamber is designed to provide a homogenous heat supply to the coffee beans, through both the modulation of the air flow volume and contact with the insulated surface of the drum. A recent development to the TTA series is the introduction of the new Opera30 roasting control, which Mazzoni calls the ideal partner to have the full control of the roasting process. “Opera30 allows you to customise recipes and process parameters in a flexible and quick way, managing the curve either by temperature or by time variables, obtaining the desired sensory profiles with the guarantee of perfect repeatability of product quality over time,” he says. The roasting data and profiles are saved within the system and available at any time. They can be organised thanks to the Roasting Manager, another new application integrated into Opera30. The system shows a preview of stored roasting curves, comparing them with the actual rate-of-rise of the product in progress. Any profile modification during the process can be manually adapted by changing the product temperature and process parameters, to adjust
