Bác cho em tai liệu, xem high pressure do nồi áp suất đó lên bao nhiêu thì valve nó xả.
Em đang ấp ủ TML theo Ý này từ lâu rồi.
Cảm ơn bác
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.

179°c at 9 bar.
Như bom rồi ...huhu
Miễn là "nấu" cf ở 93 o C và không quá 1 pGhê quá anh Metro.

"our brewer should maintain a water temperature between 195 to 205 degrees Fahrenheit for optimal extraction. Colder water will result in flat, under-extracted coffee, while water that is too hot will also cause a loss of quality in the taste of the coffee. (However, cold brew does not need any heat.) ..

Yes bác. But, 179°c là nhiệt độ tại 1st boiler, 2nd boiler có nhiệm vụ điều nhiệt xuống 100°c và giảm dần 93°c khi chạm ground.Miễn là "nấu" cf ở 93 o C và không quá 1 p

Cái khoản 179°c với 9 bar tại 1st boiler ,thật là ái ngại... Hehehehe...như bom dồi còn dì.
Ok bạn cho mình sdt để liên hệ. Sdt của mình 0778010886Dzị giờ sao anh? Có mua hộ hem.
Thèm quá, được mình ké.Mình nghiện ngập quá rồi - cơ khí chánh xác... 295 euro. Có anh nào giúp mình kg dzậy!
