【発明の詳細な説明】
（産業上の利用分野）
本発明は遠赤寿線を効果的に発生する成型木炭を用いた
コーヒ豆等の焙煎方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of roasting coffee beans, etc. using shaped charcoal that effectively generates far-infrared longevity lines.
（従来の技術）
従来、所謂備長炭と称せられる硬度の極めて高く燃焼性
に優れた白炭があり、この木炭は、所謂炭焼焙煎コーヒ
ーの焙煎機の熱源として、珍重されている。(Prior Art) Conventionally, there is white charcoal called Bincho charcoal, which has extremely high hardness and excellent combustibility, and this charcoal is prized as a heat source for so-called charcoal-roasted coffee roasting machines.
これは、焙煎機の熱源として用いられるオイル、ガス、
電力、炭、薪などに比べ殊に味と香りの優れたコーヒー
を焙煎し得る熱源であるためで、備長炭は単にコーヒー
焙煎用に使用出来るばかりでなく、小麦、大麦、大豆等
穀類の焙煎にも同様に利用されるし、更には、焙煎以外
の用途として、古来ウナギの蒲焼用に欠くべからざる燃
料として良く知られるものである。This is the oil, gas, and
This is because Bincho charcoal is a heat source that can be used to roast coffee with a particularly superior taste and aroma compared to electricity, charcoal, and firewood.Bincho charcoal can be used not only for roasting coffee, but also for roasting grains such as wheat, barley, and soybeans. It is also used in the same way for roasting eel, and it is also well known as an indispensable fuel for grilling eel since ancient times.
所で、この備長炭は製造するに際し二つの重要な条件が
必要とされる。即ち、一つには耐火性の極めて高い岩石
及び粘土を使用して窯を築く必要のあること、二つには
炭材として必ずウバメガシを使用しなければならないこ
とである。このウバメガシは房州、紀州の南部、室戸、
足摺岬とか暖地の海岸・半軸に生育している。しかし、
ウバメガシの生育している所は地勢急峻な痩せ地が多く
、産出量も決して多くはない。By the way, two important conditions are required when producing Binchotan charcoal. That is, one reason is that the kiln must be constructed using rock and clay with extremely high fire resistance, and secondly, Ubamegashi must be used as the charcoal material. This Ubamegashi is found in Boshu, the southern part of Kishu, Muroto,
It grows on the coast and half-axis of warm regions such as Cape Ashizuri. but,
Most of the places where Ubamegashi grows are on steep, poor land, and the production is not large at all.
従ってこれより製造される備長炭については価格も高く
、これをコーヒーの焙煎に使用する場合、その燃料費の
全体に占める割合たるや極めて大きいものがあった。Therefore, the price of Bincho charcoal produced from this charcoal was high, and when it was used for roasting coffee, it accounted for an extremely large portion of the total fuel cost.
このため製紙工程で大量に排出される製紙スラッチを利
用して成型木炭を製造する方法が特公昭５８−２９３５
１号公報に記載されている。また、特公昭６５−３８４
００号公報にはゼオライトを混合した煉炭か開示されて
おり、かかる煉炭によれば、ゼオライトの吸着機能、イ
オン交換機能を用いて燃焼生成物の二硫化炭素などの悪
臭を吸着し環境悪化を防止することができる。For this reason, a method for producing molded charcoal using papermaking sludge, which is produced in large quantities during the papermaking process, was devised in 1988-2935.
It is described in Publication No. 1. In addition, the special public service 1984-384
Publication No. 00 discloses a briquette mixed with zeolite, and this briquette uses the adsorption function and ion exchange function of zeolite to adsorb bad odors such as carbon disulfide from combustion products, thereby preventing environmental deterioration. can do.
（発明が解決しようとする問題点）
しかしながら、前者の成型木炭では木炭の組織自身がゆ
るいため、燃焼速度が早く、かつ砕は易い。(Problems to be Solved by the Invention) However, in the former type of shaped charcoal, the charcoal structure itself is loose, so the burning rate is fast and it is easily crushed.
このため備長炭に匹敵する燃焼性は得られない。For this reason, combustibility comparable to Bincho charcoal cannot be obtained.
また、ゼオライトを混入した煉炭では、環境悪化防止効

きる焙煎方法を提供するものである。That is, the present invention provides a high-quality roasting method that has a quality comparable to that of a roasting method using Bincho charcoal, but is extremely low in cost. Another object of the present invention is that far-infrared rays are extremely efficiently radiated from the four ceramics contained in the shaped charcoal used for roasting: alumina, zirconia, and magnesia with a purity of 95% or more. For foods such as roasted grains such as soybeans or broiled eel, effective heating, that is, radiation of far-infrared rays directly to the internal structure of the material being heated, results in the heating of the material. To provide a roasting method that allows roasting with appropriate color, aroma, and shape without causing the surface to burn unnecessarily.

ｌ。A coffee bean roasting test was conducted using a total of four types of briquette charcoal, including the three types of molded charcoal produced in this way and the Ubamegashi Bincho charcoal as a comparative product. That is, first, the preheating auxiliary burner of a charcoal-fired hot air roaster (Unicafé 34-D type) with a mesh-shaped rotating drum was started, and the temperature was increased by 5°C, and then the green beans (BW Santos M/18) were added. . Subsequently, after 5 minutes, the preheating auxiliary burner was shut off, and instead the charcoal blower was started to start the charcoal fire and the heat was gradually increased. Next, start the other blower to further strengthen the charcoal fire and raise the flame height to 15-2.
Continue roasting with the temperature raised to Q cm, and gradually reduce the blower while visually checking the color of the roasted beans.
Finally, roasting was completed after comprehensively evaluating the sound, color, aroma, and shape. During the test period, all of the products had good ignitability, and there was no failure during the test. Table 1 summarizes the (1) time required, (2) amount of fuel, and (3) temperature inside the roasting machine required for all four types of coffee beans to be roasted to approximately the same degree in the four types of roasting experiments.

The amount of heat generated was measured by the method of 8814. The results for the calorific value are shown in Table 3. The calorific value of the two types of briquette charcoal, blank, 1%, 5%, and mixed, is higher than that of Ubamesh Bincho charcoal. Only the calorific value of the mixed charcoal <10% is slightly lower. showed that. It is natural that the calorific value of ceramic-mixed briquette coal decreases as the amount of the mixture increases, because although ceramic particles emit far-infrared rays, they do not themselves generate heat through combustion. In this measurement, the sample charcoal piece (
The container that absorbs the heat generated by the combustion of powder) is a steel container, and it is difficult to absorb far infrared rays, so radiant heat from far infrared rays hardly constitutes a part of the calorific value. However, this is only due to special circumstances in measuring calorific value, and there is no difference in the fact that coffee beans can be sufficiently exposed to the action of far infrared rays in the method of the present invention utilized. Although it does not contribute to heating, it has been proven that the charcoal production method of the present invention has produced briquette charcoal with a calorific value greater than that of Bincho charcoal.

The far-infrared radiation spectrum is measured using a radiation characteristic measuring device (JASCO Corporation (Model EM-101)), which extracts the emissivity of the sample piece relative to the black body in the form of a curve over a wavelength of 3 μm to 30 μm. As is clear from Fig. 1, both the bincho charcoal and the molten coal containing ceramics compared to the blank exhibited extremely high emissivity in the wavelength region of 10 μm or more.
