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.

To make coffee, move the handle up to the horizontal position, the microswitch behind the handle is pressed (see picture below), and the pump starts. At this point, both the prepreg valve and the pressure relief valve are closed, while the intake valve is open (cam against the intake valve ejector, see section of E61 cooking head). When hot water is injected into the open pipes and cavities of the cooking head, the pressure rises. When the pressure exceeds 1.5 atmosphere, the prepreg valve (expansion valve) opens and hot water enters cavity 4. As a result, before the hot water is filled with 4, the coffee cake is pre-soaked at 1.5 atmospheric pressure. Once cavity 4 is filled, the hot water pressure begins to rise again until the required 8-10 atmospheric pressure

Automatic coffee machine, the stronger the coffee mill, the stronger the coffee mill.-Portable espresso machine
Is the fine coffee made by a fully automatic coffee machine stronger? the portable espresso machine requires a precise water temperature, that is, the water temperature should be 92 ~ 96 degrees. If the water temperature is too high, the coffee will be a cup of scorched bitter water, because the temperature above 96 degrees can destroy the oil in the coffee and taste bitter and astringent. 1 if you are using the Delong coffee machine in the company, it is recommended.

Extract coffee pot filter paper on top or bottom of coffee powder-what about coffee powder without filter paper
Whether the filter paper of the extraction coffee pot is placed on the coffee powder or under the coffee powder-how to increase the soaking time of the coffee powder without the filter paper; if you only use the original screen filter, there is not enough resistance, it is basically water dripping that is the extraction flow, there is not enough time to extract the essence of the coffee, and the coffee powder is often extracted unevenly, the coffee powder in the middle is over, and the coffee powder at the edge is often not extracted.
