1. Water level: use warm water and the water level is 0.5 cm below the safety valve. The safety valve will automatically relieve pressure when the lower pot pressure is too high, in order to prevent safety accidents. If the water level is higher than the safety valve, the function of the safety valve can not play normally.
2. Coffee powder: coffee powder is medium-fine-grained and filled with powder trough. when filling the powder, vibrate the powder trough properly so that the coffee powder is evenly distributed. after filling it, gently press the surface with your fingers to make the powder denser.
Process analysis:
1. Initial heat: after the kettle is heated, the air part expands by heat, resulting in pressure, and the water reaches the powder trough through the aqueduct. After soaking in water, the coffee powder expands rapidly to form pressed powder. At this time, the water in the lower pot is resisted by pressed powder, and the closed pressure in the lower pot continues to increase. The purpose of the first heat is to raise the water level to the position of the powder trough and let the coffee powder form cakes, so there is no need for high pressure and high temperature, as long as the heat is low. If you open the lid of the upper pot to observe, a small amount of coffee will flow out, and then the coffee will no longer flow out.
2. Pressurization: after the coffee cakes in the powder trough, the pressure in the lower pot begins to increase, turn the fire to medium heat, and let the pressure continue to increase.
3. Extraction: fire. The pressure of the lower pot is increased to balance with the resistance of the coffee pressed powder, turn on the fire, and let the pressure exceed the critical point of this balance. Under the action of the continuous fire, let the water quickly pass through the coffee pressed powder to get the coffee liquid with complete extraction and balanced taste.
1. It is recommended that you try to brew the coffee several times before tasting the coffee.
2. In order to avoid the coffee pot being burned empty when brewing coffee, it is normal to leave a small amount of water in the pot after brewing coffee.
3. Please do not burn the mocha pot empty to avoid damage and danger.
4. Do not directly touch the body of the mocha kettle after heating to avoid the danger of scalding.
5. If the coffee cannot reach the upper pot, the rubber washer in the middle may be elastic and tired and can be used normally just by updating.

Mazzer quantitative mill how to adjust the grinding degree of espresso coffee in Italy and other coffee areas where coffee is more popular, it is customary to grind more powder to improve the accuracy of each powder in the pulverizer, but the effect is not obvious when the coffee bean enters the grinder, the blade in the grinder will crush the coffee bean into powder. The smaller the distance between the blade and the blade, the smaller the coffee beans will be ground.
