9Barista is beautifully simple.
It has no electronics and only one moving part.
9Barista produces professional quality espresso by using a new, patented technology that sets it apart from all other espresso machines.
At its heart is a unique twin-boiler system. One boiler sets the brewing pressure, while the second regulates the brewing temperature.
The high-pressure boiler is heated on a stove top until it reaches 179ºC, increasing the pressure inside to 9 bar precisely.
At 9 bar pressure the spring-loaded valve opens, allowing water to flow from the high pressure boiler into the coil heat exchanger.
As the high pressure water from the first boiler passes through the coil, it is cooled from 179ºC to 100ºC, while remaining at 9 bar pressure. The water then passes through the fin heat exchanger where it is cooled further to 93ºC.
Now the water is at precisely the right pressure and temperature to pass through the ground coffee, producing a perfect crema-cloaked espresso in the cup at the top.
Simple, but at the same time, deliciously clever.
