Description

TECHNICAL FIELD [0001] The present invention relates to a drip coffee extracting apparatus and a drip coffee extracting method using the same,

The present invention relates to a coffee extracting apparatus and a method for extracting coffee by extracting coffee by pouring hot water into ground coffee beans, and it is an object of the present invention to provide a coffee extracting apparatus and extracting method for extracting coffee, So that the coffee taste is good but the taste can be guaranteed.

Drip coffee is a method of extracting coffee only after pouring water into a finely pulverized coffee bean (coffee ground powder) and extracting only coffee. In order to extract the original flavor and aroma to the maximum, a simple tool and filter And it can be used in coffee shops as well as at home because it can best express taste according to coffee production or roasting degree.

There are various kinds of drip apparatuses for extracting drip coffee according to the drip method. The most typical method is to put the paper filter in the de-pipper and put the dripper in the server (the apparatus for extracting the coffee) I put coffee in a dripper, pour hot water and drop coffee, and the coffee goes down to the server at the bottom of the dripper as the water passes through the beaker and the filter in the dripper.

In other words, when hot water is poured into the coffee powder, the coffee pressure is lowered as the coffee bean in the beverage melts in the water as the water pressure acts on the bean.

However, the problem of dripping with such hot water is that the extraction of coffee is very careful because the amount of water to be dropped must be adjusted appropriately while the amount of hot water of the coffee is kept constant. In order to improve the taste of coffee, I need a lot.

In other words, when you pour hot water, when you pour in only one point, you will pour out the coffee powder evenly, because the coffee is not extracted evenly. When you pour hot water, check the amount of water from the dripper, It is very troublesome to use it because it needs to pour the coffee in the divided ratio.

In addition, the drip mechanism has a sub, a dripper, and a paper filter, and many exercises are required to use each of them well. Particularly, a user who is not skilled in water draining has a problem that coffee powder is not completely filtered, , A coffee filter, and a paper filter, so that the practice can be performed to extract the original taste of the coffee as it is.

Therefore, recently, a cupping type (typically a clever type) has been proposed so as to eliminate the hassle of such coffee extraction and to make it easier to use.

It is made easy to use by most people who are not proficient in water drainage. It is filled with coffee powder in a dripper and filled with water for the amount of coffee to be eaten. Stir for a certain time (about 3 to 4 minutes) , And when the steamer is completed, the dripper is placed on the server and the valve of the dripper is opened to extract the coffee contained in the dripper at a time, so that it is close to dripping into the water.

However, such a fall-off type has a merit that it is convenient to use but has a disadvantage that coffee is very weak. That is, since the coffee powder contained in the coffee powder is not easily extracted because the water pressure does not act on the coffee powder during the extraction of the coffee, the coffee taste is deteriorated and the coffee powder must be used more for the deep taste of the coffee.

In other words, although it is convenient to use the falling-out method, there is a problem that the taste and coffee efficiency of the coffee are lower than the drip method in which coffee is extracted by the flow of water.

In addition, both of the above-mentioned methods for lowering the drip coffee have a method in which a paper filter is put in a dripper. In the paper filter, since the oil component of coffee is adsorbed on paper during the extraction of coffee, In addition, paper filters that are subjected to external influences such as exposure during distribution may suck moisture in the air and smell.

Therefore, it is cumbersome to maintain it in a sealed container so as to avoid foreign matter.

Since the raw material of the paper filter is pulp, it may be harmful to the human body, and the filter used for disposable use is costly and has a bad influence on the environment.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the present invention includes an extractor body 10, an upper filter 20 and a lower filter 30 mounted on the extractor body 10, and coffee contained in the extractor body 10 And a mounting portion 50 for mounting the extractor main body 10 on the server 100. [

The extractor main body 10 is for extracting coffee components of coffee grounds by containing coffee grounds and hot water and is formed with an inner space 12 opened on the upper side to contain coffee powder and hot water, A discharge port 14 is formed on the bottom surface for discharging the extracted coffee.

The extractor main body 10 is preferably made of a transparent material such as glass and has a handle 16 formed at one end of the extractor main body 10 and an inner space 12 It is preferable to install the lid 18 so that the lid 18 can be blocked or blocked.

The filter inserted into the inner space 12 of the extractor body 10 is divided into a lower filter 30 mounted close to the bottom surface of the extractor body 10 and a lower filter 30 And an upper filter 20.

The upper filter 20 is disposed at an upper portion of the coffee powder so that the coffee powder contained in the extractor body 10 is separated from water while allowing the water to permeate into the coffee powder in its separated state.

The lower filter 30 is mounted close to the bottom surface of the extractor body 10 in order to discharge only the extracted coffee without scrambling off coffee powder when dripping coffee.

The upper filter 20 and the lower filter 30 may be formed in the form of a porous net. The upper filter 20 and the lower filter 30 are preferably made of a metallic material such as stainless steel, which is semi-permanently usable, rust-proof and harmless to the human body.

The upper filter 20 and the lower filter 30 may further include a fitting 60 for fitting the upper filter 20 and the lower filter 30 apart from each other.

The fitting structure of the fitting 60, the upper filter 20 and the lower filter 30 is such that the tongues 22 and 32 are formed at the center of the upper filter 20 and the lower filter 30, Can be formed in the shape of a rod and fixed to the tread.

At this time, the outer circumferential surfaces of the upper filter 20 and the lower filter 30 are mounted in close contact with the inner wall of the inner space 12 of the extractor body 10, and the inner circumferential surfaces of the treads 22, And sealing elements 24 and 34 so as to be in close contact with the outer circumferential surface of the housing.

The sealing elements 24 and 34 are used to prevent coffee powder from leaking out in a state where coffee powder and water are contained in the extractor body 10. The sealing elements 24 and 34 are made of a silicone material which is harmless to the human body, 30 to be sealed so as to be sealed.

Therefore, only the minimum amount of water for invoking the coffee powder is permeated by the double-layered filter built in the extractor body 10, and water pressure acts on the coffee powder Can be extracted.

At this time, when the stopper 62 for preventing the lower filter 30 from being detached is formed at the lower end of the fitting hole 60, the lower filter 30 is prevented from being arbitrarily separated from the state where it is assembled to the fitting hole 60 The separation distance between the lower filter 30 and the bottom surface of the extractor body 10 can be adjusted by changing the height of the seating surface 62a of the stopper 62 on which the lower filter 30 is seated. It is preferable that the lower filter 30 is mounted at a predetermined distance so as to secure a discharge flow passage of coffee filtered through the lower filter 30 without being completely in contact with the bottom surface.

The fitting hole 60 is formed to be relatively protruded from the height at which the upper filter 20 is mounted, so that it is used as a handle for pulling out the upper filter 20 and the lower filter 30 after the coffee extraction is completed .

The valve 40 is provided to allow coffee to be discharged through the outlet 14 after the extractor body 10 is filled with coffee powder and hot water to complete the steam boiling operation. And a valve body 44 for blocking or opening the flow path of the valve body 14 is incorporated.

The outlet 14 formed in the extractor body 10 is vertically and vertically formed so that the valve body 44 vertically penetrates the outlet 14 horizontally and is attached to the valve body It is preferable that the blocking wall 44a of the blocking wall 44a is opened and closed by rotating the blocking wall 44a so that the blocking wall 44a is rotated by the operation of the lever 44b drawn out to the outside, So that the opening / closing operation can be performed simply from the outside of the main body 10.

The method for extracting coffee using the drip coffee extracting apparatus includes a step (S100) of inserting a lower filter into an extractor main body having an inner space formed therein, and a step of filling the inner space of the extractor main body into which the lower filter is inserted (S300) of setting an upper filter and a lower filter on the upper and lower sides of the coffee powder by inserting an upper filter into the extractor main body, a step S300 of placing the hot water in the inner space of the extractor main body, A step S500 of waiting for a certain time to allow the water contained in the inner space of the extractor body to permeate through the upper filter and impregnating the coffee powder into the coffee flour (S500), and a step (S500) And opening the valve formed at the outlet of the main body to extract coffee (S600).

This coffee extraction method will be described in more detail as follows.

First, the extractor body 10 is prepared, and the lower filter 30 is inserted into the extractor body 10 so as to be close to the bottom surface of the extractor body 10 before putting coffee powder and hot water into the prepared extractor body 10. At this time, it is preferable that the lower filter 30 be inserted into the fitting hole 60 so that the upper filter 20 can be inserted into the upper side of the lower filter 30.

In the state where the lower filter 30 is inserted, coffee powder ground coffee beans is filled into the extractor body 10, and the upper filter 20 is put on the upper part filled with the coffee powder, so that the coffee powder is mounted on the upper and lower sides respectively Is isolated by the upper filter (20) and the lower filter (30).

Then, the extractor body 10 is filled with heated water at a suitable temperature before and after 90 占 폚, which can maximize the taste of hot water, and most preferably coffee.

Then, the water contained in the inner space 12 of the extractor body 10 is permeated through the upper filter 20, soaking in the coffee powder for a certain period of time. At this time, the time for putting the moxibustion varies depending on the taste of the coffee, but it is suitable for about 3 to 4 minutes.

After the hot water is absorbed in the coffee powder and steamed, the valve 40 is opened while the extractor body 10 is placed on the server 100, and the coffee is extracted and dripped.

Therefore, the water content of the coffee powder is extracted by the water pressure of the coffee powder in the state where the coffee powder is called by the hot water, and the yield of the coffee can be improved.

At this time, in order to allow the hot water to penetrate into the coffee powder in a state where coffee powder and hot water are contained in the extractor body 10, a valve for blocking the flow path of the discharge port 14 in forming the structure of the valve 40 It is possible to allow the water to be absorbed by the coffee powder to be improved by allowing the body 44 to communicate with the inner space 12 of the extractor body 10 even when the valve body 40 is shut off.

That is, the inner space 12 of the extractor body 10 and the outside air outside the discharge port 14 are ventilated with each other, so that the pressure does not rise inside and the water flowability is improved to be well impregnated into the coffee powder. When the lid 18 is closed on the upper part of the extractor body 10, the inflow pressure is generated in the state where hot water is contained in the extractor body 10, and the water is discharged toward the discharge port 14 to further induce the flow of water. The hot water is evenly absorbed throughout the coffee powder, which can make the steamer more effective.

On the other hand, after the coffee is dripped, the coffee is extracted between the upper filter 20 and the lower filter 30, and the remnants, that is, the coffee grounds remain. As shown in FIG. 8, The lower filter 30 is attached to the stopper 62 on which the lower filter 30 is placed so that the coffee grounds are kept completely between the upper filter 20 and the lower filter 30 The coffee beans can be easily separated because the coffee grounds are not left in the inner space of the extractor body 10 in spite of the fact that the coffee beans are extracted by pressing the coffee beans.
