Coffee extraction principle

Coffee extraction principle

There are a variety of coffee-making equipment and different methods, but the core extraction principles are all the same.

The core process of coffee extraction principle:

1 crushing coffee beans to increase the surface area of coffee in contact with water

2 the coffee powder is fully soaked in the aqueous solution, and the coffee essence is hydrophilically dissolved.

(3) separate coffee solution and coffee grounds.

All modern coffee extraction is the two core processes of soaking and filtration, which belongs to the category of physics, and there is basically no chemical change in the process. The differences in the thickness of coffee powder, the length of soaking time, the method of separation and filtration, and so on, have created a wealth of coffee making utensils and techniques.

At present, some of the more primitive coffee extraction methods, such as direct brewing coffee and Turkish coffee, are not filtered by some coffee producing villages in Ethiopia, but most modern people prefer a pure taste rather than a mouthful of coffee grounds.
