Petroncini TT 15

the verdict

the TT 15 sits in the range where many specialty roasters need both flexibility and enough capacity to supply a retail program or small wholesale account. the 3 to 15 kg batch window handles everything from dialing in a new single origin to running weekend cafe inventory without constant back-to-back roasting. the cast iron flywheels and ferritic drum give you stable conduction, while separate controls for burner, airflow, and drum speed let you push convection when you want faster development or pull it back for longer, more conductive roasts. profile logging means you can document successful roasts and train new operators from recorded data rather than verbal notes. independent suction for roasting and cooling lets you drop a batch and start preheating the next immediately, which matters when you're trying to finish 60 kg before lunch. expect a learning curve if you're used to more automated machines, this roaster assumes you know how to read a roast and adjust on the fly.
