DUTCH COFFEE MATER AND DUTCH COFFEE MAKING METHOD [0001]

The present invention relates to a Dutch coffee maker and a method for producing Dutch coffee. More particularly, the present invention can extract a large amount of Dutch coffee in a relatively short time and maintain a constant temperature, It is possible to surely prevent the Dutch coffee that can be automatically extracted and automatically extracted and stored from overflowing from the receiver and to extract and store the Dutch coffee in the same space so that the Dutch coffee maker capable of storing hygienically and stably To a method for producing Dutch coffee.

Generally, Dutch coffee refers to coffee made by pouring water into finely pulverized coffee such as drip coffee.

Drip coffee is divided into several types depending on the type of filter used, but it is common that hot water is poured into finely ground coffee beans. Dutch coffee, unlike drip coffee, is coffee that is extracted by pouring cold water instead of hot water.

How to make a Dutch coffee is called "water drip" and it is a kind of drip coffee. The water drip method is called Dutch coffee because it is a method developed in the Netherlands.

Caffeine, one of the greatest features of coffee, is extracted from a temperature of about 70 ° C, so it is hardly extracted from caffeine in Dutch coffee extracted with cold water, but the bitterness of coffee is extracted very much.

In recent years, the popularity of Dutch coffee has been increasing in recent years because the apparatus of the Dutch coffee stimulates a lot of curiosity to the consumers, and the extracting apparatus is decorative and has a taste to be enjoyed by the eyes.

However, because hot coffee uses cold water compared to general extraction methods using hot water, it takes a long time for cold water to pass through the ground coffee in order to get enough flavor, and a drop of water in the coffee powder It is difficult to absorb water in the whole of the coffee powder since the water is concentrated only in the center portion from the entire container containing the coffee powder.

In addition, Dutch coffee provides water at normal temperature when it supplies water to ground coffee beans. Since the temperature at room temperature may change according to the season or indoor air-cooling temperature, it is not always possible to supply water at a constant temperature. There was a difficulty in extracting coffee with taste and flavor.

In addition, there is a problem that the storage tank for storing the raw water for producing the Dutch coffee is very difficult and troublesome to clean frequently.
