公知である。As the beverage extractor described above, a cylinder and a filter block are combined vertically, and after pouring the raw material and hot water into the cylinder, the interior of the cylinder is pressurized and the mixed liquid of the raw material and hot water permeates the filter block to form a beverage. Those which are adapted to be extracted are known.

ルタである。FIG. 2 shows a conventional structure of such a beverage extracting device. In the figure, 1 is a cylinder having a lifting valve mechanism 2 built therein, and 1a and 1b are raw material charging shooters opened toward the inside of the cylinder 1 and hot water. A supply pipe, 3 is a vertically movable filter block combined with the lower part of the cylinder, 3a is a fixed filter made of punching metal mounted on the upper surface of the filter block 3, 4 is an air pump for blowing pressurized air into the body of the cylinder 1, Reference numeral 5 is a disposable paper filter fed from a roll.

シリンダ１の外に搬出して滓容器に回収する。The beverage extraction operation with the above configuration is performed as follows. First, the valve mechanism 2 is made to stand by at the raised position, and the raw material and hot water are poured into the cylinder 1 with the filter block 3 being in close contact with the lower surface of the cylinder 1. Then, the air pump 4 is started to blow pressurized air into the body of the cylinder 1 to stir the raw material and the hot water. When this agitation is completed, the valve mechanism 2 is lowered while blowing pressurized air to close the upper surface of the cylinder 1 and pressurize the inside of the cylinder. As a result, the beverage is extracted through the paper filter 5 and the fixed filter 3a, and is discharged from the filter block 3 to a beverage cup (not shown) and supplied. Also,
When all the beverage is extracted, the valve mechanism 2 is raised and returned, the filter block 3 is lowered, the paper filter 5 is sent out, and the raw material slag 6 remaining on the paper filter is carried out of the cylinder 1. Collect in a slag container.
なお上記の加圧エアに換えてピストン加圧により抽出
する方式のものもある。There is also a system in which extraction is performed by pressurizing a piston instead of the above pressurized air.
ところで、前記した従来の飲料抽出装置で飲料抽出後
に原料滓の一部がシリンダの壁面に付着残留し、この残
り滓が次回の飲料抽出動作の際に新たに投入した原料と
混ざり合って飲料の風味を損なうと言った問題点があっ
た。By the way, a part of the raw material slag remains on the wall surface of the cylinder after the beverage is extracted by the conventional beverage extraction device described above, and the residual slag is mixed with the newly added raw material at the time of the next beverage extraction operation to make the beverage. There was a problem saying that the flavor was spoiled.
すなわち、飲料抽出の最終工程でシリンダ１の内部に
残った原料滓６の大半は紙フィルタ５と一緒にシリンダ
１より排出されるが、湿潤状態にある原料滓６の一部は
シリンダ１の内壁面に付着したまま排出されずに残留す
る。That is, most of the raw material slag 6 remaining inside the cylinder 1 in the final step of beverage extraction is discharged from the cylinder 1 together with the paper filter 5, but a part of the raw material slag 6 in the wet state is stored in the cylinder 1. It remains on the wall without being discharged.
このように原料滓がシリンダの壁面に付着残留する原
因は次記の点にあることが考察により明らかになった。
すなわち、シリンダ１は樹脂成形加工等によって一般に
内壁全面が平滑になっている。このために湿潤状態の原
料滓６がシリンダ１の壁面に付着残留し易くなる。It was clarified from the following points that the reason why the raw material slag adheres to and remains on the wall surface of the cylinder is as follows.
That is, the cylinder 1 generally has a smooth inner surface due to resin molding or the like. For this reason, the raw material slag 6 in a wet state easily adheres to and remains on the wall surface of the cylinder 1.
本発明は上記の点にかんがみなされたものであり、シ
リンダの壁面に原料滓が付着残留するのを巧みに回避し
て常に良質な飲料を抽出できるようにした飲料抽出装置
を提供することを目的とする。The present invention has been made in view of the above points, and an object of the present invention is to provide a beverage extraction device capable of always extracting a high-quality beverage by skillfully avoiding the residue of the raw material adhered and remaining on the wall surface of the cylinder. And
上記課題を解決するために、本発明の飲料抽出装置に
おいては、飲料抽出工程終了時にシリンダ内に残った原
料滓と触れ合うシリンダの下部内壁面を粗面となして構
成するものとする。In order to solve the above problems, in the beverage extraction apparatus of the present invention, the lower inner wall surface of the cylinder that comes into contact with the raw material slag remaining in the cylinder at the end of the beverage extraction process is configured to be a rough surface.
上記のようにシリンダの下部内壁面に細かな凹凸を形
成して梨地状の粗面とすることにより、該粗面に触れ合
う原料滓は面接触とならずに点接触となり、壁面が平滑

の壁面から容易に離脱してシリンダ外に排出される。し
たがって次回の飲料抽出時に前回の原料滓が混ざり合っ
て飲料の風味を損なうことがなくなり、常に良質な飲料
を製造できる。By forming fine irregularities on the inner wall surface of the lower part of the cylinder to form a matte rough surface as described above, the raw material slag that comes into contact with the rough surface becomes point contact instead of surface contact, and the wall surface is smooth. The contact area is smaller than in some cases. As a result, when the filter block is lowered after the beverage is extracted, the raw material slag that has been in contact with the inner wall surface of the cylinder is easily separated from the wall surface of the cylinder and is discharged to the outside of the cylinder. Therefore, the next time the beverage is extracted, the previous raw material mixture will not be mixed and the flavor of the beverage will not be impaired, and a good beverage can always be produced.

ダが樹脂成形品である場合には成形時に梨地面とするこ
とで形成できる。また壁面の粗面化により得られる原料
滓の離脱効果については、実機テストの結果からも十分
に確認されている。It should be noted that the rough surface of the cylinder wall surface can be formed by brazing, or when the cylinder is a resin molded product, it can be formed into a matte surface at the time of molding. In addition, the desorption effect of the raw material slag obtained by roughening the wall surface has been sufficiently confirmed from the results of the actual machine test.

ンダ１の内壁面下部領域、つまり第２図で述べたように
飲料が抽出された後にシリンダ内の底部に残った原料滓
６と触れ合う面域が凹凸な梨地状を呈する粗面1cとして
形成されている。FIG. 1 shows the structure of the embodiment of the present invention, in which the lower part of the inner wall surface of the cylinder 1, that is, the raw material slag 6 remaining at the bottom of the cylinder after the beverage is extracted as described in FIG. The contacting surface area is formed as a rough surface 1c having an uneven matte surface.

リンダ１の壁面に原料滓が付着残留することが無くな
る。With this configuration, the filter block 3 is provided after the beverage is extracted.
When the lowering operation (see FIG. 2) is performed, the raw material slag that has been left on the bottom of the cylinder and is in contact with the rough surface 1c is easily separated from the rough surface 1c and discharged to the outside of the cylinder 1. The raw material slag will not adhere to and remain on the wall surface of.
本発明の飲料抽出装置は、以上説明したように構成さ
れているので、次記の効果を奏する。Since the beverage extraction device of the present invention is configured as described above, it has the following effects.
すなわち、飲料抽出工程終了時にシリンダ内に残った

できる。That is, by making the lower inner wall surface of the cylinder that comes into contact with the raw material slag remaining in the cylinder at the end of the beverage extraction process to be a rough surface, when the filter block is lowered and separated from the cylinder after beverage extraction, The raw material slag remaining inside is securely separated from the inner wall surface of the cylinder and is almost completely discharged from the cylinder. Therefore, at the time of extracting the next beverage, the raw material slag of the previous time is not mixed and the flavor of the beverage is not impaired, and a high-quality beverage can always be produced.
