Mình nghiện ngập quá rồi - cơ khí chánh xác... 295 euro.
Mình đang nghiên cứu có mua trực tiếp về được hay không vì bọn này ship bằng DHL express. Credit card thì ai cũng có rồi thêm mấy chục đồng tiền ship nữa thôi. Cái lăn tăn là còn thuế má các kiểu làm khó làm dễ gì không?

Có một anh đã ngỏ ý giúp nhưng ảnh tuốt ngoài HN nên mình hơi thiếu tự tin.

Mua máy pha cafe, anh nào có mối ship đồ uk không nhỉ?

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.

Ghê quá anh Metro.

179°c at 9 bar.

Như bom rồi ...huhu

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.

Cái khoản 179°c với 9 bar tại 1st boiler ,thật là ái ngại... Hehehehe...như bom dồi còn dì.
