AI Technical Summary
Technical Problem
Espresso machines face challenges in controlling the temperature of brew water effectively due to slow heating mechanisms like thermoblocks, which result in uneven temperature profiles and detract from espresso extraction quality.
Method used
A group head with a resistive thick film heater and flow diffuser is integrated into the espresso machine, allowing for rapid and uniform heating of brew water to a user-selected temperature between 89°C and 96°C, using a corrosion-resistant material with high specific heat capacity and feedback control.
Benefits of technology
This solution enables rapid heating of brew water to the optimal temperature range within 10 seconds, ensuring consistent espresso extraction quality and reducing temperature inconsistencies.
