1: make a cup of good quality Espresso coffee machine, how much Bar is enough?2: how can you know the real pressure of coffee machine without providing information?3: many professional coffee machine pressure is more than 10Bar, but under normal circumstances only need 9Bar is enough, since it does not need so high pressure, please ask more out of what use?
The factors that determine a good cup of coffee include the variety of coffee beans, the size of the coffee powder, the pressure of the coffee machine, the temperature of the water, the tightness of the handle of the coffee powder, and then the technique. So 9BAR 15bai can, mainly to see the degree of mastery of techniques.
1. 19BAR2. is difficult to define. But if in the case of pressing powder, 7G, compaction, the machine out of coffee flowing, and coffee oil thick, then the machine pressure is more than 15 pa3. the pressure changes when the machine is working. The supplied pressure is not all high pressure. Like the power system of an automobile, the speed of the machine varies. Sometimes 2000 revolutions per minute. Speed up, it is necessary to increase the speed of the machine
1: make a cup of good quality Espresso coffee machine, how much Bar is enough?Answer: Italian coffee association standards -9bar.2: how can you know the real pressure of coffee machine without providing information?Answer: most commercial machines are indicated by pressure gauges.3: many professional coffee machine pressure is more than 10Bar, but under normal circumstances only need 9Bar is enough, since it does not need so high pressure, please ask more out of what use?Answer: even if 100bar can be achieved, is meaningless, because completely blocked it, how much pressure can not come out; the machine can provide 9BAR rotary vane pump start pressure, not to say, anyway, the pressure is 9, a coarse brown powder fast, fine out coffee, or the slow, in short, these two are difficult to drink, the right is under the pressure of 9BAR, 30ml concentration 15----30 seconds. For the commercial machines, the pressure of the electromagnetic pump for household machines is gradually increased, the safety pressure value set by 0-------, the higher the safety pressure value, the better the performance of the pump!
High pressure steam coffee machine is a kind of Italian coffee machine.Espresso machine and pump steam Italian Italian Italian steam, refers to the so-called high pressure steam pressure, but only 3 5BAR (1BAR = 1 ATM), only to make American drip coffee machine than some strong coffee, and no oil containing crema coffee, and Mocha about the pot.Pump pressure coffee machine, there is the pressure generated by the pump, the common is 15BAR pump pressure, such machines can make crema containing fat coffee, is the real espresso coffee.
As a rule, it takes 9 of pressure to make it thickNo data, basically not see the pressure, the general factory in the 9 PA or so, there are special pressure measuring powder bowl.The boiler needs a margin to prevent it from exploding
