In fact, the working principle of automatic freshly ground coffee machine is more complicated than that of instant coffee machine, which is to put it bluntly, the artificial brewing of coffee powder is fully automated. The working principle of the coffee grinder is much more than that, including grinding beans, filtration and extraction, pressing powder.
1. Grinding
The heart of the freshly ground coffee machine is the grinder, but the function of the grinder is not only the grinding of coffee beans, grinding is the first step of the coffee machine, and the fine and rough grinding can also be used as one of the standards to judge the quality of a coffee machine. If the company's freshly ground coffee machine grinds the beans with very small particles, and the grinding speed is super fast, it is second to none in the market.
2. Strain cooking and extraction
The ground coffee will be introduced into a place similar to the "micro boiler" for boiling. After a certain amount of coffee powder is collected, the "micro boiler" will automatically become a fully closed structure and rapidly filter the coffee powder. The process is similar to that of brewing tea leaves. Extract the essential coffee liquids and oils and distribute them to the final outlet of the coffee machine.
In principle, this vessel can be called a part of "grinder". The extraction process is another standard to test the quality of the coffee machine. A good coffee machine can achieve thorough extraction, completely separate impurities from pure coffee, and fully retain the oil and foam with coffee fragrance. Therefore, the two steps of the grinder control the key part of the work flow of the fully automatic freshly ground coffee machine.
3. Press powder
The so-called "micro-boiler" in the previous step will extract the remaining coffee impurities in the furnace, and through automatic shrinkage and internal pressure, the impurities will be quickly pressed into a standard flat cake, commonly known as "powder cake", and finally through a fixed channel, the powder into the built-in garbage utensil, which needs to be cleaned regularly by the user, coffee impurities cake has the function of eliminating odor. So for the newly decorated room or can do the last "in addition to the smell" of the force.
The above is the working principle and process of automatic freshly ground coffee machine. The working principle of most freshly ground coffee machines on the market is roughly the same, but whether each step can be complete, thorough, stable and rapid is an important internal standard for judging quality.
