The present invention relates to a coffee extraction device.

In general, the coffee extraction device refers to a device for extracting the taste and flavor components from the coffee by grinding the ground coffee (grinding) roasted coffee beans.

Here, coffee extraction refers to extracting the coffee ingredients according to the characteristics of the roasted beans, the grains of the ground beans, the contact time between the water and the ground coffee, and the filtering device. When hot water penetrates the ground coffee particles and the soluble components dissolve, the dissolved components elute out of the coffee particles. Use the principle that the concentration of the soluble components remaining in the coffee particles and the soluble components in the hot water are the same.

Such coffee extraction can be divided into four ways as follows.

A decoction (for example, Turkish coffee) that puts water and coffee powder in the brewing container for a short period of time and then dries the coffee powder after it has settled down. Wait for it to dissolve and then mix in an infusion (for example, French press) to allow the coffee powder to sink and drink, and to pour coffee powder into the brew container and pour hot water over it Brewing (e.g. coffee makers, hand drips, water drips), and compressed extraction (e.g. Mokapot, espresso) are known.
