Specialty Roasters Roasting
Machine overview
High technology for your Specialty Roastery
Available in three models, TT5/10, TT15/20 and TTG60 the Petroncini Specialty Roasters are the perfect choice to achieve countless sensory profiles, developing the coffee’s deepest aromas, from light roasting to the very darkest, obtaining excellent final results in terms of repeatability, consistency and uniformity.
The thermal energy cycle adopted by the Specialty Roasters allows for the gentle drying and caramelisation of the coffee sugars, putting the source of heat not in direct contact with the roasting chamber. The Specialty Roasters thus offer a soft roasting profile which allows for even heat distribution to the beans, taking care of the raw materials so as to achieve high quality aromatic profiles.
These machines are equipped with high-performance and modulating technological components, which allow for full control of the roasting process.
Thanks to heat, roasting air volume and the drum rotation speed controls, Specialty Roasters can let you vary the method of transferring heat to the bean, achieving the perfect balance between convection and conduction, according to the desired end product.

TT5/10
The TT5/10 Specialty Roaster is a compact, high‑precision roasting solution designed for small specialty roasteries, training centres, and coffee labs. Engineered to roast from 3 to 10 kg per batch, it enables roast masters to explore countless sensory profiles, from delicate light roasts to deep, dark ones, with excellent repeatability and uniformity.
TT15/20
The TT15/20 Specialty Roaster builds on the strengths of the TT5/10, offering greater batch capacity while preserving the same level of sensory control and flexibility. With a roasting range of 10 to 20 kg per batch, it is tailored for specialty roasteries looking to increase output without compromising quality and aroma consistency.
TTG60
Its hourly capacity of about 240 kg and the manual management of the working phases make TTG 60 ideal for small-scale industrial roasters who don’t want to give up the pleasure of artisan roasting of their own coffee. TTG 60 is an easy-to-use, reliable and cost-effective machine that combines the complete freedom of manually roasting, combined with the guarantee of the highest manufacturing quality and long-life operation of devices installed.
The equipment is easily set up so that time-to-commissioning and maintenance operations are definitely reduced, ensuring high profitability standards.
