Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a Dutch coffee mass-

The present invention relates to a Dutch coffee making apparatus for extracting Dutch coffee using cold water and a coffee extractor used therein.

In general, Dutch coffee refers to coffee that has been used for a long time by using cold water or normal-temperature water instead of hot water. Dutch coffee is a Japanese name for Dutch coffee, and English for "cold water" is called cold brew.

The origins of Dutch coffee are that sailors who transported coffee to Europe from the Dutch colonies were looking to drink coffee during long-term voyages. Today, it has unique flavor and aroma, making a separate Dutch coffee making device to extract the hot coffee.

Depending on the method of extraction, it is divided into a dropping method and a leaching method. Dripping is a way to make a cup of coffee drip from a container, which is why it is called "coffee tears". The leaching method is a method in which the ground beans and water are added to the container and aged at room temperature for about 10 to 12 hours, and then the residue is filtered to remove the undiluted solution.

Among them, the apparatus for producing a pointed Dutch coffee includes a cold water passage for providing cold water, a coffee extract passage provided thereunder at intervals therebetween, and a stock solution reservoir for collecting the coffee stock solution provided therebetween at intervals. Therefore, if the coffee beans are ground in the coffee extractor and the cold water or the room temperature water is dropped by the coffee extractor in the cold water container, the coffee is extracted from the coffee extract container for 3 to 4 hours for a short time and 8 to 12 hours for a long time. The concerned coffee stock solution is extracted into the stock solution reservoir.

Because it is extracted for such a long time, it is less bitter than ordinary coffee extracted in a short time with hot water, and it can feel soft and smooth flavor. The degree of grinding of bean, taste of water and extraction time are important. The extracted coffee liquid is stored in a sealed refrigerator. If it is matured for a day or two at a low temperature, the flavor will survive more. It is common to drink milk or syrup or water to dilute or drink with ice depending on the taste

However, the conventional pointed type Dutch coffee making apparatus has a problem that it is difficult to mass-produce since it is only possible to produce a small amount of about 1 to 2 liters, and the apparatus and its structure used in such small- There are many problems in production and it is difficult to apply them simply.

However, the conventional large capacity low temperature permeable liquid coffee extractor has the following problems.

The coffee powder stored in one large capacity coffee extracting bin 10 called "large capacity extracting machine " is rapidly inflated by the supply of cold water, and the large capacity coffee extracting bin 10 may explode.

In addition, in a place where a water road is formed in the horizontal direction in the coffee powder stored in the large-capacity coffee extracting bin 10 due to the cold water sprayed from the side injector 220 and the coffee is not uniformly disturbed, There is a problem that it is extracted.
