A heat exchanger allows a coffee machine to brew espresso and steam milk at the same time, without waiting for temperature adjustments. It works by transferring heat from the boiler to cold water flowing through a metal tube, instantly heating it to the perfect brewing temperature. This design ensures:
- Speed: No downtime between brewing and steaming.
- Efficiency: One boiler serves two functions.
- Consistency: Stable brewing temperatures for perfect espresso.
How Does It Work?
- The boiler holds hot water and steam.
- A metal tube (heat exchanger) runs through the boiler.
- Cold water flows through the tube, absorbing heat from the boiler.
- The result: hot water for espresso and steam for milk frothing — simultaneously.
