Description

A manufacturing apparatus for Dutch coffee

The present invention relates to a Dutch coffee making apparatus, and more particularly, to a Dutch coffee making apparatus capable of extracting a coffee liquid while extracting a large amount of Dutch coffee in a short period of time while maintaining the taste and aroma of the coffee as much as possible will be.

In recent years, water-dripped Dutch coffee has been popular among coffee aficionados for extracting and drinking coffee liquid from coffee powder for a long time by using cold water.

Typical coffee is drip coffee or espresso coffee, which is a method of putting coffee powder into a filter and pouring hot water. However, it is characterized by the fact that coffee is extracted for a long time by dropping hot water or cold water at a drop of cold water.

In this way, since cold water or cold water is used, the coffee aroma and flavor that can be blown away when hot water is used is extracted as it is. In other words, you can feel the subtle taste that you can not feel in hot coffee such as deep taste of coffee, rich aroma and bitter, sour, sweet.

In addition, Dutch coffee is less caffeine and can be stored for long periods. In other words, coffee caffeine occurs when it is mixed with water above 80 ℃, and because it uses cold water or cold water at room temperature, caffeine is less than coffee extracted with warm water.

However, in the process of dropping water in the coffee ground powder, it is difficult to absorb water in the whole of the coffee ground since the water concentrates only in the center of the whole container of the coffee grounds, It has been difficult to extract coffee.

In order to solve such a problem, a technique disclosed in Korean Registered Utility Model No. 20-0469626 as shown in FIGS. 1 and 2 has been proposed. The technical feature thereof is that a coffee storage unit 110 in which ground coffee is stored; A water storage part 120 for storing water to be supplied to the coffee storage part 110; An extraction stock solution storage part 130 located below the coffee storage part 110 and storing the coffee stock solution extracted from the coffee storage part 110; And a water supply unit (140) for supplying water from the water storage unit (120) to the coffee storage unit (110), wherein the water supply unit (140) A spray nozzle 141 located above the water storage part 120 for uniformly spraying water supplied from the water storage part 120 into the coffee storage part 110; A water supply pump 142 for pumping water stored in the water storage unit 120 and supplying the water to the spray nozzle; And a water supply hose connected to the water storage part (120), the water supply pump (142) and the spray nozzle (141) so that water pumped by the water supply pump (142) (143).

However, although the technique described in Korean Utility Model No. 20-0469626 has an advantage of constantly supplying water at a constant temperature, not only does it take much time to manufacture the Dutch coffee, but also water is uniformly distributed throughout the whole coffee powder There is a problem that it is difficult to stably extract the coffee liquid from all the coffee grounds.
