Description

植物性素材ブロック形成方法に関する。The present invention relates to a method for forming a vegetable material block.

特許文献１には、飲料製造残渣である飲料原料有機質の２００μｍ以下の微細粒子を、原料粘土に対して乾燥質量換算で０．５～１３質量％となる割合で混合して成形した粘土成形体を焼成して粘土焼成品を製造する。茶殻やコーヒー殻の有機質の焼失により多孔性の粘土焼成品が得られ、吸水性、調湿性及び消臭性に優れている。 In Patent Document 1, fine particles of 200 μm or less of beverage raw material organic matter, which is a beverage manufacturing residue, are mixed with the raw material clay at a ratio of 0.5 to 13% by mass in terms of dry mass to form a clay molded body. is fired to produce a fired clay product. By burning off the organic matter of used tea leaves and coffee grounds, a porous baked clay product is obtained, which is excellent in water absorption, humidity control and deodorizing properties.

しかしながら、特許文献１の製造方法はコーヒー殻を原料粘土に混合する必要があり、この方法で製造された粘土焼成品はコーヒーの香りが低下する問題があった。本発明は、植物性素材に由来する香りを低下させることなく固化可能な植物性素材ブロック形成方法を提供することを目的とする。However, the production method of Patent Document 1 requires mixing coffee husks with raw clay, and the fired clay product produced by this method has a problem that the aroma of coffee is reduced. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for forming a plant material block that can be solidified without reducing the aroma derived from the plant material.

本願発明は、乾燥させたコーヒー抽出かすを所定形状に形成するコーヒーブロック形成方法であって、筒状に形成され、少なくとも一端側が開放されている金属製の筒状体に前記コーヒー抽出かすのみを充填し、前記筒状体に充填された前記コーヒー抽出かすを前記筒状体の一端側から圧縮し、前記コーヒー抽出かすを圧縮した状態で、前記筒状体の外周面をリグニンの熱軟化温度である１３４～２３５℃に加熱するコーヒーブロック形成方法を提供する。The present invention is a coffee block forming method for forming dried ground coffee grounds into a predetermined shape, wherein only the ground coffee grounds are placed in a cylindrical body made of metal having at least one end open. and compressing the coffee grounds filled in the cylindrical body from one end side of the cylindrical body, and in a state where the coffee grounds are compressed, the outer peripheral surface of the cylindrical body is thermally softened by lignin. A coffee block forming method is provided that heats to a temperature of 134-235°C .

本発明の実施形態に係るコーヒーブロック形成方法により形成されたコーヒーブロックは図１に示すように、コーヒー粉５が円柱形状や四角柱形状に形成されたものであり、これを所定長に切断等して使用される。図２～４を参照して本発明の実施形態に係るコーヒーブロック形成方法を説明する。本実施形態に係るコーヒーブロック形成方法は、コーヒー豆を粉砕したコーヒー粉５が所定形状に形成されたコーヒーブロック１を形成する。まず図２に示すように筒状に形成され、少なくとも一端側が開放されている金属製の筒状体１０にコーヒー粉５のみを充填する。次に図３に示すように、筒状体１０に充填されたコーヒー粉５を筒状体の一端側から万力２０により圧縮し、図４に示すようにコーヒー粉５を圧縮した状態で、筒状体１０の外周面にヒーター３０をセットし、筒状体１０を加熱する。また、加熱中に筒状体１０に充填されたコーヒー粉５を筒状体１０の一端側から再圧縮してもよい。The coffee block formed by the coffee block forming method according to the embodiment of the present invention is, as shown in FIG. used as A coffee block forming method according to an embodiment of the present invention will now be described with reference to FIGS. The coffee block forming method according to the present embodiment forms the coffee block 1 in which coffee powder 5 obtained by pulverizing coffee beans is formed into a predetermined shape. First, as shown in FIG. 2, only the coffee grounds 5 are filled into a metallic tubular body 10 which is formed in a tubular shape and is open at least at one end . Next, as shown in FIG. 3, the coffee grounds 5 filled in the tubular body 10 are compressed from one end side of the tubular body by a vise 20, and the coffee grounds 5 are compressed as shown in FIG. A heater 30 is set on the outer peripheral surface of the tubular body 10 to heat the tubular body 10 . Further, the coffee powder 5 filled in the cylindrical body 10 may be recompressed from one end side of the cylindrical body 10 during heating.

本実施形態によれば型にコーヒー粉をつめ圧縮・熱を加えることでリグニン（高等植物の木化に関する高分子のフェノール性化合物）の働きにより固形化するのでコーヒー豆を粉砕したコーヒー粉のみで固形化することができる。According to this embodiment, the mold is filled with coffee grounds, compressed, and heated to solidify by the action of lignin (a high-molecular phenolic compound related to lignification of higher plants). It can be solidified.

本実施形態ではコーヒー粉５をコーヒーの抽出かすを乾燥させたものを用いることができる。ここでコーヒーの抽出かすは、一般的に家庭用消臭剤に使われている活性炭とよく似た構造をしており、この多孔質な構造によりコーヒーの抽出かすの表面積が増え、いやな臭いをキャッチし、吸収する。
また、コーヒーの抽出かすは酸性のため、アルカリ性であるアンモニアを中和させアンモニア臭を抑えることができる。In this embodiment, coffee grounds 5 obtained by drying extracted coffee grounds can be used. The coffee grounds here have a structure very similar to that of activated carbon, which is commonly used in household deodorants. catch and absorb
In addition, since coffee grounds are acidic, ammonia, which is alkaline, can be neutralized and the smell of ammonia can be suppressed.

筒状体１０は、筒の直径３４ｍｍ、長さ６０ｍｍ、筒肉厚２ｍｍの寸法で形成されている。本実施形態のコーヒーブロック形成方法では、この筒状体１０をヒーター３０にて１１分間加熱する。（ヒーター３０に温度制御する機能がついていない場合には、温度の過剰上昇を防ぐため、こまめにヒーター３０のスイッチを入り切りするのが望ましい。）The cylindrical body 10 is formed with a diameter of 34 mm , a length of 60 mm, and a wall thickness of 2 mm. In the coffee block forming method of this embodiment, the cylindrical body 10 is heated by the heater 30 for 11 minutes. (If the heater 30 does not have a temperature control function, it is desirable to turn the heater 30 on and off frequently in order to prevent an excessive rise in temperature.)

再圧縮のタイミングは、加熱開始からのおおよそ６分後と１１分後が望ましい。The timing of recompression is preferably about 6 minutes and 11 minutes after the start of heating.

ヒーター３０による加熱温度はリグニンの軟化温度以上に熱することが望ましい。リグニンとはコーヒーの抽出かすに含まれる成分で、これに圧力を加えるとリグニンが溶け接着剤の役割をし、同じくコーヒーの抽出かすに含まれるセルロースとヘミセルロースが接着される事で成型できる。リグニン、ヘミセルロース及びセルロースの熱軟化温度は、例えば、乾燥状態では、それぞれ、１３４～２３５℃、１６７～２１７℃及び２３１～２５３℃であり、湿潤状態では、それぞれ、７７～１２８℃、５４～１４２℃及び２２２～２５０℃である。The heating temperature by the heater 30 is desirably higher than the softening temperature of lignin. Lignin is a component contained in coffee grounds, and when pressure is applied, lignin melts and acts as an adhesive, and cellulose and hemicellulose, which are also contained in coffee grounds, adhere to each other and can be molded. The heat softening temperatures of lignin, hemicellulose and cellulose are, for example, 134-235° C., 167-217° C. and 231-253° C. respectively in the dry state, and 77-128° C. and 54-142° C. respectively in the wet state. °C and 222-250 °C.

上記実施形態では、植物性素材の一例であるコーヒーを例に説明したが、本発明の植物性素材はコーヒーに限らず、茶葉、花、果実（果実の皮のみを含む）等であってもよい。この場合、上記実施形態に於いて、コーヒー粉５の代わりに上記の植物性素材を用いることで植物性素材ブロックを得ることができる。In the above embodiment, coffee, which is an example of a plant material, was described as an example, but the plant material of the present invention is not limited to coffee, and may be tea leaves, flowers, fruits (including only fruit skins), etc. good. In this case, in the above-described embodiment, the plant-based material block can be obtained by using the above-described plant-based material instead of the coffee grounds 5 .
