Description

[Detailed description of the invention] This invention relates to a corrugator used as an extractor for drip coffee, tea strainer, black tea strainer, etc.

When extracting coffee, green tea, black tea, etc., it is best to use a hot water that is highly concentrated and does not contain impurities, and once the hot water has permeated the coffee powder, green tea leaves, or black tea leaves, it should be filtered as quickly and uniformly as possible. is known as the best method of said extraction.

The first purpose of this invention is to provide a system that allows anyone to uniformly extract coffee, green tea, black tea, etc., which are considered to be optimal, without requiring any special techniques.

A second object of the present invention is to provide a device that achieves the above-mentioned first object with a simple structure and at a low cost.

The present invention will be explained in more detail below with reference to an embodiment of the accompanying drawings.

1 is a main body with a wide opening at the top and a narrow opening at the bottom; in this example, an inverted conical funnel shape is shown, but the shape can be an inverted polygonal pyramid, an inverted open pyramid, etc. Although it is limited to this embodiment as long as it has a narrow opening at the bottom, it is not O.

Reference numeral 2 denotes a spacing strip 2 that projects radially upward from the narrow side portion of the inner surface of the main body 1, with the narrow side facing high and facing upward and low.In this embodiment, the spacing strip 2 is formed into a valley by the protruding strip. Although the one that forms the void portion is shown, in this proposal, the main body 1
It is sufficient that the distance between the main body 1 and the corrugated body 4 on the inner surface is large on the narrow side and can be kept low facing three directions. The strip 2 is not limited to the protrusion in this embodiment.

Reference numeral 3 denotes holes that communicate with the inside and outside of the main body 1 in the valley between the spacing strips 2, 2, and in this embodiment, the holes 3 with slanted angles are bored in the valleys between the spacing strips 2, 2, respectively. The first condition of the holes 3 is that the inside of the main body 1 can be ventilated with outside air whose temperature is lower than that of the inside of the main body 1 during use, but the number of holes 3 depends on the hanging extraction. Any number of containers can be selected depending on the relationship between the liquid storage container and the extraction raw material.
In addition, the structure of hole 3 is similar to that in the extract liquid storage container and main body 1 during extraction.
Any structure is sufficient as long as the steam staying in the gap between the spacing strips 2 and 2 between the corrugated body 4 and the corrugated body 4 can be discharged to the outside of the main body 1.
The present invention is not limited to the structure of this example.

In the figure, 5 is a projecting edge, 6 is a handle, 7 is a locking hole, and 8 is an extract storage container.

As mentioned above, the main body 1 has a wide opening a at the top and a narrow opening at the bottom, and radial spacing strips 2, 2, 2, etc. are formed in three directions from the narrow side of the inner surface of the body 1. The spacing strips 2 are formed with the narrower side facing higher and lower, and one or more holes 3 are bored in the main body 1, which forms the valley between the spacing strips 2, and communicating with the inside and outside of the main body 1. , and since the filter body 4 such as filter cloth or filter paper is attached to the inner surface of the main body 1, when using this wave guide, coffee powder, green tea leaves, or black tea leaves cannot be placed inside the filter body 4. The extraction raw materials into which the hot water has been poured are immersed in the hot water in the body 4, and then extracted together with the hot water as an extract liquid.

Then, the coffee, green tea, or black tea extraction raw material becomes the immersed and accumulated layer inside the corrugated body, and the hot water extracts and filters the immersed and accumulated layer and becomes an extract liquid. ... In other words, it hangs down toward the narrow mouth side, and is stored hanging inside the extract storage container 8, and during extraction, the inside of the extraction liquid storage container 8 and the spacer strips 2, The steam accumulated between the two is discharged through the hole 3 to the outside of the main body 1, which has a lower temperature than the inside of the main body 1.

In this case, the spacer strips 2, 2.2, . , it is possible to obtain an extract having a uniform concentration from the extraction raw material in the transfer body 4.

In other words, the larger the distance between the cross body 4 and the valley between the spacing strips 2, 2, the faster the filtration and extraction speed is, while the smaller the distance, the slower the filtration and extraction speed, and the thicker part of the immersed and retained layer of the extraction raw material is filtered. In view of the fact that the filtration efficiency is good in the thin or small portions where the efficiency is low, deep spaced grooves 2 are placed in the lower part of the passing body 4 where the immersion and retention layer of the extraction raw material is thick and the filtration efficiency is poor.
The spacing strips 2 are made shallower toward the top of the cross body 4, where the immersion and retention layer of the extraction raw material gradually decreases and the filtration efficiency improves, and the filtration speed from the cross body 4 is slowed. Even if the extraction raw materials are thickly accumulated and stacked below 4, it is possible to filter and extract an extract liquid with a uniform concentration.Moreover, in this case, the outer side of the main body 1, which is the valley between the spacing strips 2, Since one or more holes 3 leading to the
The steam inside the main body 1 generated from the extract liquid trapped in the valley between the extract storage container 8 and the spacing strips 2 during the extraction work of the extraction raw material does not come into close contact with the transfer body 4 because the outside air temperature is lower than the inside of the main body 1. Since the outside air is smoothly discharged out of the main body 1 through the hole 3 in the section, steam is trapped in the extract liquid storage container 8 and the valley between the spacing strips 2 and 2 during the extraction operation to obtain a uniform concentration, which prevents the extraction operation. It is possible to obtain an extract liquid with a uniform concentration without inhibiting the flow of the extract liquid due to resistance.

Furthermore, since the present invention has an extremely simple structure, it can be provided at a low cost, and anyone can reliably obtain an extract with a uniform concentration without requiring any special techniques for use. It is possible to provide something that anyone can easily use, regardless of whether or not they have it, and is extremely convenient in practice.
