Press the extraction button, after pressing, about 3-4 seconds before the coffee will flow out, during this period take two coffee cups on the extraction mouth. The extraction time is about 25 seconds and the extraction amount is also in 25ML.

To skillfully grasp the time of this process, the reason is that after the coffee beans are ground into coffee powder, the freshness can be maintained for up to 15 minutes, otherwise the taste will not be too good. This is why it is necessary to grind and do it.

Espresso will have a layer of oil on its surface, giving it a unique flavor. It is the base of all fancy coffee. Knock the coffee powder out of your hand and wipe it with a towel to make it cleaner. Grind the coffee, gently flatten the coffee powder with your fingers, use a filler to fill the coffee powder, about 10 kilograms of strength, gently rotate, and repeat 2 times to become coffee cakes.

Espresso tends to use finer particles, with a fineness between salt and flour. The amount of powder used is about 18g.

The surface of the powder bowl should be cleaned to make the sealing ring more sealed. Finally, put the hand on the brewing head for extraction.

In the Italian coffee machine, the temperature value is mainly affected by the size of the boiler or heating block, as well as good heat conduction materials, there is an obvious difference between the toy machine and the professional Italian coffee machine. In general, many standard toy machines are equipped with small boilers (below 200ml) or small heating blocks, so it is difficult to achieve a stable temperature, and the temperature fluctuates greatly in the process of coffee extraction. The machines of many small household appliance brands are like this (such as Cankun, Delong, Electrolux, etc.). After all, these brands are not professional coffee makers. Another thing to consider is a good heat conduction material, a good machine has a better circuit and pipeline design, using copper or stainless steel as the main material of the coffee machine, they have good thermal conductivity (to ensure uniform and stable temperature). Otherwise, it is still more than 90 degrees from the boiler to 70 or 80 degrees from the coffee machine, which will be more obvious in the low temperature environment.
