Description

HAND DRIP COFFEE APPARATUS AND AUTOMATIC COFFEE DRIPPER}

The present invention relates to an automatic coffee drip machine, and more particularly, in order to provide an optimal drip coffee rich in coffee flavor and aroma, by dropping while rotating water in a spiral manner, so that the contact of the powdered coffee powder particles and water does not overlap. The active ingredient of coffee relates to a hand drip coffee device and an automatic coffee drip machine using the same, which can be properly extracted and prevent the extraction of harmful components.

Various techniques have been developed to extract coffee drinks having a rich taste and flavor, and coffee materials for preparing such coffee drinks include instant coffee and ground coffee.

Instant coffee has the advantage that it is easy to manufacture a coffee drink, but there is a problem that the unique taste and flavor of coffee is reduced. Coffee beans are more cumbersome to produce coffee beverages than instant coffees, but they are widely used because of their superior taste and flavor.

There are drip and espresso methods for the manufacture of coffee beans. The espresso method provides coffee raw materials in various ways such as pure coffee powder, coffee pads, and coffee capsules to facilitate coffee extraction. This espresso method has the advantage of producing caffeine with low caffeine while maintaining the taste and flavor of the coffee beverage, but since each raw material can be used only to enjoy different types of coffee, different types of espresso Purchase of a separate machine or complicated modifications are required.

On the other hand, the coffee beans extracted using the coffee beans in a coffee shop or home is manufactured using an automatic coffee drip machine (coffee maker) of the general drip method.

Coffee is extracted through the process of infiltration, dissolution and separation, where water penetrates into the ground coffee particles to dissolve soluble components in water, and the dissolved components diffuse through the coffee particles. Finally, the eluted components are extracted by extracting them with water.

This process is briefly described through a conventional automatic coffee drip machine as follows. First, a filter made of paper, a metal / polymer mesh, or the like is mounted on a hopper of an automatic coffee drip machine, and then ground coffee powder is put into the filter. Then, when water is poured into a tank that boils water and serves as a hopper, boiled water is provided to the coffee beans in the filter, and the coffee beans are stored in the coffee pot under the automatic coffee drip machine. The lower part of the coffee pot is provided with a heater that heats the coffee pot to keep the coffee beans accommodated in the coffee pot cool.

When using an automatic coffee drip machine, it is possible to extract the coffee beans simply by supplying the coffee powder and water, and there is an advantage that the coffee beans extracted by the warming function can be kept warm. However, if the coffee beans are extracted and retained in large quantities, the taste and aroma of the coffee beans are rapidly lowered as time passes, and in some cases, they are burnt. In particular, there is a problem that the contact between the beans powder and water is not constant so that the bitter taste of the coffee is excessively extracted to enjoy the natural taste and aroma of the coffee. In other words, the coffee beans are extracted while the water passes through the coffee powder for a long time. When the coffee beans are extracted, only the active ingredients contained in the coffee powder are extracted at the beginning of the coffee beans extraction, but the longer the coffee beans are extracted, the more harmful ingredients contained in the coffee powder, such as caffeine or bitter taste. This increase reduces the taste and aroma of the coffee beans. In addition, there is a problem that the coffee powder is extracted immediately without the time to deliver the taste and aroma to the water while the water is used to extract the coffee beans are extracted into the coffee powder without stopping during extraction.

The present invention is to solve the above problems, an object of the present invention is to drop while rotating the water in a spiral so that the constant contact between the coffee beans and the water does not overlap so that the effective ingredient of the coffee is properly extracted and harmful It is to provide a hand drip coffee device and an automatic coffee drip machine using the same to prevent the extraction of the ingredients to produce an optimal drip coffee rich in flavor and aroma of coffee.
