World of Coffee 2022: Precision Engineering and Automation Take Center Stage

Advancements in Grinder Maintenance

Fiorenzato showcased a significant leap in grinder usability with their 83mm flat burr pro model. The standout feature is a removable burr chamber that allows for daily cleaning without losing the grind setting. Traditionally, dismantling a grinder meant tedious recalibration. This system preserves the collar position, ensuring that the chocolatey and nutty profiles typical of large flat burrs remain consistent after maintenance. It also features a grind-by-weight system with a precision variance of only 0.1 grams.

The Shift Toward Fully Automated Roasting

Two major players, Aillio and Roest, are redefining the shop roasting experience through high-density sensing and automation. The Aillio IO utilizes a 2-kilo capacity and a patented infrared sensor with 192 sensing points to monitor drum dynamics in real-time. It handles the entire process—from pneumatic bean loading to automated cooling tray transfer—via cloud-based recipes.

Roest is pushing similar boundaries with their upcoming Roest P3000 prototype. By employing 18 different sensors, including four dedicated solely to averaging bean temperature, they have achieved a level of batch-to-batch consistency where curves overlap perfectly. Their focus on simplified maintenance—like cleaning a cyclone with a power drill attachment—suggests a future where high-end roasting is accessible to staff with minimal technical training.

Thermal Stability in Multi-Boiler Systems

XLVI is tackling thermal shock through complex multi-boiler architectures. Their flagship 55 Volante features six separate boilers for a three-group machine, allowing independent control over steam and group head temperatures. By heating water in three distinct stages—the main boiler, a spiral coil, and a 7.5kg group head boiler—they ensure the water hits the puck with absolute stability. This level of customization extends to electronic steam power control and automated milk temperature shut-off, proving that aesthetic design can coexist with extreme technical specs.
