petroncini petroncini tt 15
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.
what it does well
- 3 to 15 kg range covers sample refinement and small production without needing two machines
- independent roasting and cooling suction systems let you run batches back-to-back without thermal compromise
- manual control over heat, air, and drum speed gives experienced roasters direct influence over roast development
- cast iron and ferritic construction delivers thermal consistency across long roasting days
where it stops short
- profile logging captures data but doesn't automate execution, so every batch still needs active operator input
- heavier construction and manual controls make this slower to operate than comparable automated 15 kg machines
- 15 kg maximum becomes a throughput limit if your program grows past 150 kg per week
