How to make it concentrated and fill it with powder? How do you make espresso? What are the skills?

Many coffee shops seem to learn the filling method from the same chef: "knock three times"! First gently press, knock three times, then press three times, then press again, and then put it on the outlet head.

Is the coffee powder pressed as tightly as possible?

No wonder someone goes to get a special filling machine.

This seems to be a deliberate attempt to make things difficult for the pump! The tighter you press, the shorter the pump life. Over the years, I have found that the pump damage rate of Taiwan's commercial espresso coffee machine seems to be particularly high. If you use it for half a year, it will make a strange noise. Is the life of the pump really that short?

When the pump breaks down, some manufacturers will replace the motor at a price ranging from 10 to 20, 000, but do you know that the models used in business are usually motor pump or pump (most small machines are integrated)? Even if it is the pumping motor at home, it is to add a pump outside the motor! The pump may be easy to break, but the motor is not! Do you think Italy's industrial technology will be lower than that of Taiwan? So Italian motors are easy to break? So it's usually the pump that breaks down, not the motor! And the pump is more expensive than the motor! But no matter how expensive it is, it will not be more expensive than changing the whole set of motors + Bang Pu.

Why is Pop easy to break? It has something to do with work stress.

The pump is actually a supercharger (turbo). In theory, the pressure after the pump is fixed. However, the compactness caused by the thickness, uniformity and filling strength of the powder will change the actual pressure. This is like the exhaust system of a turbo; turbocharging is the most efficient intake system, but if one end of the exhaust is not matched properly, it not only consumes fuel but also reduces efficiency.

The thickness of the powder and the filling method directly affect the quality of the coffee and the life of the pump!

Another cause of unstable pump pressure and thus affecting life is the water quality. The internal structure of the pump is precise, and poor water quality will cause wear and tear. This is why the filter is installed and soft water is used.
