[0001] APPARATUS FOR EXTRACTING DUTCH COFFEE USING LOW TEMPERATURE [0002]

The present invention relates to a low temperature Dutch coffee extracting apparatus, and more particularly, to a low temperature Dutch coffee extracting apparatus capable of extracting aseptic state Dutch coffee through a closed and low temperature refrigeration and sterilizing function.

In general, Dutch coffee refers to coffee that has been extracted using cold water or normal temperature water. 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.

Recently, a water drip type of Dutch coffee has been widely used among coffee lovers for extracting and drinking coffee liquid from coffee powder for a long time by using cold water.

For the production of Dutch coffee, put the ground beans into a special appliance, and extract the coffee stock solution in cold water or room temperature for 3 to 4 hours for short time, 8 to 12 hours for long time. Depending on the extraction method, it is divided into the drop method and the leaching method.

The dripping method is to drop coffee from the container by a drop, which is why it is called 'coffee tears'.

The leaching method is a method in which ground beans and water are put into a vessel and aged at room temperature for about 10 to 12 hours, and then the residue is filtered by filtering the residue.

Because it is extracted over a long period of time, it is less bitter than ordinary coffee extracted in a short time with hot water, and it can feel a mild and soft 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.

Generally, it is common to drink milk or syrup or water to dilute or drink with ice depending on the taste rather than just drinking the raw coffee.

In the conventional Dutch coffee extracting apparatus, the water tank in which water is stored, the coffee tank storing the crushed coffee powder, and the coffee container containing the extracted Dutch coffee are each exposed, and there is a high possibility that foreign substances such as dust in the air are introduced, When the hot coffee is extracted at a relatively high temperature as in the summer, the flow rate is slowed down by the gravity. As a result, there is a risk of propagation of bacteria such as Escherichia coli by controlling the flow rate manually. Moreover, There was a problem that it was more difficult to give incense with bitter taste, sour taste, salty taste and the like.

In addition, the existing Dutch coffee extracting apparatuses are opened without a lid at room temperature, so that they are directly affected by the temperature change, and the microorganisms reproduce, and not only the fine dust but also the impurities are contained. The cochlea and the upper water bottle portion, So that it is difficult to clean.

In order to solve this problem, a technique for an extraction device capable of preventing the propagation of bacteria in the Dutch coffee during the extraction was sought.

An invention such as Korean Patent Laid-Open Publication No. 10-2016-0082301 (name of invention: Dutch coffee extracting apparatus) has been proposed as a conventional technique.
