petroncini petroncini tt 5

the TT 5 is built for sample roasting and small-batch specialty work where you need production-grade construction in a compact format. the 1 to 5 kg range handles everything from single-bag test roasts to small retail batches without the thermal instability you get from running a larger machine under capacity. cast iron flywheels and ferritic drum walls give you the same heat retention characteristics as the bigger Petroncini models, so profiles translate upward when you scale recipes to a 15 or 30 kg machine. the manual controls and profile logging let you document what you're doing without locking you into automated sequences. it's slower to operate than a fully automated roaster and requires more skill to drive consistently, but that's the point. this machine suits roasters who treat sample evaluation and small-batch development ascraft work rather than a procurement checkbox.
