What's the difference between modern coffee machine extraction head and E61?

E61 another function praised by the world is the automatic prepreg function. The hot water pressure of making espresso is equivalent to 8: 10 atmospheric pressure, and if the water under such high pressure is applied to the surface of the coffee cake at once, it is not very beneficial for coffee extraction, so engineers who design and make coffee machines should try to avoid it. On E61, an expansion cavity (cavity 4) is designed to slow down the pressure establishment process. In addition, hot water from the boiler through the inlet to cavity 1, cavity 2, cavity 3 and then to the water distribution network, it has to go through tortuous and narrow pipes, which play a good role in limiting current. Therefore, for the E61 head, the hot water pressure is slowly established, and this pressure establishment process is called preleaching.

In addition, because it is imported by the whole machine, his Sheung Shui mouth is a three-point port instead of a four-point port commonly used in China. if you need to connect the water, you need to buy an interface adapter ring separately, and in order to protect the machine, it is highly recommended that you connect a separate water filter in front of the water supply.

Some E61 users responded that the steam was not easy to control when milking, because I basically only drank strong, and occasionally I felt that the effect and operation were all right, and it was a little more difficult to make cappuccino. It should be more a matter of habit.

The water diversion net has been removed. It's time to wipe the water distribution plate. Look up at the cooking head and you will find a large slotted screw. This is the disperser. The water separator is made of copper, so it should be cleaned with a copper wire brush. Coffee stains can be easily removed by adding a coffee maker cleaner to the brush. Make sure that all coffee residues on the surface are wiped off before reloading the parts.

Now it's time to assemble the water distribution net and the rubber ring. As mentioned earlier, the water distribution network of the head is fixed by a rubber ring. Take out the new rubber ring and pay attention to placing the bevel up and squeeze the water diversion net into the rubber ring. Put the two assembled parts on top of the handle without a filter bowl and buckle the handle to the brewing head as usual to make coffee, so that the rubber ring will be put into the ditch.
