How to Add Pressure to a Mocha Pot-How to Cook Oil in a Mocha Pot

How to add pressure to the mocha pot-how the mocha pot boils oil

We should feel lucky when we see the small hole breathing. Because it shows that the mocha pot in front of you is a mocha pot of high quality. The small hole that will steam we generally call the pressure relief valve is a safety device, it can steam means that its function is normal, it can discharge too much pressure from the pot for you, so as to avoid the danger of explosion of the mocha kettle. Generally speaking, the pressure relief valve can be regarded as a standby role, but it may occur in the following two situations.

Situation 1:

Coffee powder grinding is too fine and excessive filling when filling the powder trough, these two actions appear at the same time in the use of mocha pot is more inappropriate. Because it is not a heat exchanger with enough pressure or a household pump, the water vapor pressure generated by the mocha kettle is not enough to penetrate the compact powder layer you have filled, and continuous heating will cause a continuous increase in water vapor. but if too much vapor pressure cannot be eliminated, the mocha pot will easily explode.

Of course, the pressure on the lower seat has been increasing all the time, just like blowing a balloon to blow up a mocha pot and exploding, at this time, the pressure relief valve set up for safety will play a role in draining the excessive pressure and mixing it with the water vapor to improve the method is very simple, do not grind so fine, as long as it is a little finer than the siphon pot; do not over-fill, tap the powder trough to make the coffee powder dense.

Case 2:

No grinding too fine, there is no filling pressure, but it will still exhaust steam from the pressure relief valve. Normal use, but why is there still water vapor discharge? How long have you been using your mocha pot? Perhaps because of your years of use, the rubber o-ring inside the pressure relief valve has lost its elasticity, so although you use it normally, it does not produce too much pressure. However, as the pressure relief valve's ability to accumulate pressure has been reduced due to the aging of the parts, it has been drained out before the pressure can push the water through the powder layer to the upper seat.
