Automatic coffee machine to adjust the degree of grinding? change the grinder roast degree of coffee beans flavor description
Introduction to the description of the flavor of coffee beans with automatic coffee machine to adjust the degree of grinding.
Adjust the amount of coffee powder: all automatic coffee machines have the function of adjusting the amount of coffee powder. The adjustment of the amount of powder does not necessarily adjust the concentration of coffee. If you increase the amount of coffee powder within a certain range, the concentration of coffee will increase. If you go beyond this range, the concentration of coffee will not rise, just like we have two cups of the same amount of water. We added one spoonful of sugar and two spoonfuls of sugar respectively to the two cups of water. If the water is saturated with one spoonful of sugar, then adding two spoonfuls of sugar cannot improve the sweetness of the water.
The same is true for adding and reducing powder. Usually a fully automatic coffee machine with electronic temperature control technology can ensure that the coffee produced is kept at an ideal constant temperature. If the coffee machine had two boilers, it would be better to control the temperature
From the point of view of the coffee machine, making Espresso requires brewing a cup of 30ml espresso at 9 atmospheric pressure, 90 degrees water and 30 seconds. Therefore, according to the requirements of the pump, it is necessary that it be able to produce a continuous and stable pressure. Usually, the pump pressure 15bar can be used as a reference value.
The grinder's knife structure (flat knife / knife), speed, knife balance, knife concentricity, and other factors will lead to differences in the uniformity and shape (smooth / angular) of the ground coffee powder, and the extraction effect is different.
In addition, even with the same semi-automatic coffee machine and bean grinder, the operation of different coffee bars will lead to a great difference in the effect of extraction. Every cup of coffee in Shaoxiu is delicious coffee, which is not the taste of full automatic energy. However, when it comes to 2B coffee bar, every cup is dead coffee, which is not the taste of full automatic energy.
