【発明の属する技術分野】
本発明は、熱した小石の上でサツマイモを焼いて食する石焼芋装置の改良に関する。
【０００２】
【従来の技術】
従来の石焼芋装置では、釜内に置いた小石を下から熱して、その小石上にサツマイモを置いて焼いている。
【０００３】
【発明が解決しようとする課題】
従来の石焼芋装置では、釜内に置いた小石を下から熱して、その上にサツマイモを置いて焼いているだけであり、サツマイモ全体を十分に焼き上げるまでには皮の部分が乾燥して固くなり、また時間と共に皮が焦げて食する部分が少なくなるという問題があった。また、従来の石焼芋装置では釜内の温度や湿度の調節が困難であり、焼け具合を調節する必要のある他の食材を焼くには適していなかった。
【０００４】
本発明は、サツマイモの皮を焦がさずにおいしく焼き上げると共に、その他の野菜、魚、肉等を含むがそれに限らないその他の食材も焼くことができる装置を得ることを目的としている。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明の石焼調理装置においては、従来の石焼芋装置と同様にサツマイモ等の食材を焼くための小石を底面に任意の深さで敷くように収容した釜の下部で燃料を燃やして小石を加熱するが、同時に当該小石を熱するための熱を利用してボイラーでお湯を沸かし、発生した蒸気を熱した小石の下にパイプで適量導き、当該小石で覆われたパイプ部分に任意の間隔で開けた孔から噴出させ、噴出した水蒸気が熱した小石に触れて更に加熱膨張して小石の上に置いた食材を囲繞し、当該食材を蒸し焼き状態にできるようにする。
【０００６】装置をコンパクトにするためにボイラーは溶接等により竈の壁面又は小石を入れる釜と一体化することもできる。
【０００７】食材は釜の中に敷いた小石の上に直接に置いて焼くこともでき、また、支柱を有する台を小石の上に置き、当該台上に食材を置いて焼くこともできる。
【０００８】蒸気パイプの一端はボイラー上部空間の蒸気溜部分に接続し、蒸気パイプの他端は釜の縁を越えて釜の中に敷いた小石の中に埋設するように伸ばし、当該他端の末端は閉塞しておき、小石に埋まったパイプ部分の側面に任意の間隔で小孔を開けて蒸気を小石の間から噴出させるとよい。また、当該蒸気パイプは、小石の下に埋設する部分で任意に枝分かれ又は曲折させ、小石の敷かれた全面にわたって蒸気を噴出させることもできる。
【０００９】蒸気を釡に導く蒸気パイプの途中に調節バルブを設けて、蒸気量を調節又は停止できるようにするとよい。蒸気を停止して、従来の石焼芋装置と同じ状態にして、サツマイモ等の高温で焼くことで香ばしさをだす必要がある食材を高熱の小石の上に直接置いて焼くことができる。蒸気を供給すれば、小石の上に置かれた食材は蒸し焼き状態になり皮まで柔らかく仕上げることができる。調理時間や仕上がりの柔らかさは、供給蒸気量を調節バルブで調節することにより変えることができる。
【００１０】高温の小石の上に直接置いて焼くのに適していない食材を焼くために、支柱により小石から離間させた台、網又はバーベキュー用焼き串を支える横桟等を釜に固定して設置し又は暫定的に小石の上に置いて、当該台、網又は桟上に食材を置いて焼くこともできる。このように食材を小石から離すことで、主として小石等からの輻射熱により蒸気雰囲気中で蒸し焼きすることになり、比較的低温での調理に適する食材も焼くことができる。
【００１１】ボイラーの上部空間の蒸気溜部分に蒸気パイプとは別にベント用パイプを接続し、当該ベント用パイプに調節バルブを設けて釜に供給する蒸気量及び蒸気圧を調節できるようにするとよい。
【００１２】顧客の注目を引く目的で、蒸気圧調節のために設けたベント用パイプの先端等に蒸気で吹鳴できる笛等を設け、蒸気圧調節用のバルブ操作で吹鳴の強弱又は長短等を制御してもよい。
【００１３】給水パイプの一端は、ボイラーの底面近くでボイラーに接続し、給水パイプの他端に設けた給水口の高さは、ボイラー内に適量の蒸気溜部分の空間を残すように設定した上限水面の高さに合わせ、ボイラー内の水面が当該上限水面より高くなったら当該給水口から水があふれるようにして、ボイラー内の水の膨張又は蒸気圧等で水面上昇して蒸気パイプを通って釜に水が噴出するのを防ぐようにするとよい。
【００１４】装置は、水及び燃料を一緒に持参することで自動車、リヤカー等に搭載し、又は自動車、リヤカー等で牽引して移動することができる。
【００１５】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement in a potato apparatus for burning sweet potatoes on heated pebbles and eating them.
[0002]
[Prior art]
In the conventional stone-baked potato apparatus, pebbles placed in a pot are heated from below, and sweet potatoes are placed on the pebbles and baked.
[0003]
[Problems to be solved by the invention]
In the conventional stone potato apparatus, the pebble placed in the pot is heated from the bottom, the sweet potato is placed on it and baked, and the skin part is dried until the whole sweet potato is fully baked There has been a problem that the skin becomes hard and the part that burns with time decreases. Further, it is difficult to adjust the temperature and humidity in the pot with the conventional stone-baked potato apparatus, and it is not suitable for baking other foods that need to be adjusted in the degree of burning.
[0004]
An object of the present invention is to provide an apparatus capable of baking sweet potato skin deliciously without burning, and baking other ingredients including but not limited to other vegetables, fish, meat and the like.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, in the stone-roasting cooking device of the present invention, as in the conventional stone-roasting potato device, a pot in which pebbles for baking ingredients such as sweet potatoes are accommodated so as to be laid at an arbitrary depth on the bottom surface. At the bottom of the boil, the fuel is burnt to heat the pebbles, but at the same time, using the heat to heat the pebbles, the water is boiled in a boiler, and the generated steam is guided by a pipe under the heated pebbles, and Sprayed from a hole opened at an arbitrary interval in the covered pipe part, the spouted steam touches the heated pebbles, further heats and expands, surrounds the food placed on the pebbles, and the food can be steamed To do.
[0006] In order to make the apparatus compact, the boiler can be integrated with the wall of the kiln or the pot for storing pebbles by welding or the like.
[0007] Food materials can be placed directly on a pebble laid in a kettle and baked. Alternatively, a table having columns can be placed on the pebble, and the food material can be placed on the pedestal and baked.
[0008] One end of the steam pipe is connected to the steam reservoir in the upper space of the boiler, and the other end of the steam pipe is extended beyond the edge of the kettle so as to be buried in a pebble laid in the kettle. The end of the pipe may be closed, and a small hole may be opened at an arbitrary interval on the side surface of the pipe portion buried in the pebbles, and steam may be ejected from between the pebbles. Further, the steam pipe may be arbitrarily branched or bent at a portion buried under the pebble, and the steam may be blown out over the entire surface on which the pebble is laid.
[0009] An adjusting valve may be provided in the middle of a steam pipe for guiding steam to the kama so that the amount of steam can be adjusted or stopped. The steam is stopped, and the same state as that of the conventional stone-baked potato apparatus is used, and foods that need to be fragrant by baking at a high temperature, such as sweet potatoes, can be directly placed on high-heated pebbles for baking. When steam is supplied, the ingredients placed on the pebbles are steamed and can be softened to the skin. The cooking time and the softness of the finish can be changed by adjusting the amount of supplied steam with a control valve.
[0010] In order to bake foods that are not suitable for baking by directly placing them on hot pebbles, a stand separated from the pebbles by columns, a net or a horizontal bar supporting a barbecue skewer is fixed to the kettle. It can also be placed or tentatively placed on pebbles, and the foodstuffs placed on the table, net or pier and baked. By separating the foodstuff from the pebbles in this manner, the foodstuff is steamed in a steam atmosphere mainly by radiant heat from the pebbles and the like, and the foodstuff suitable for cooking at a relatively low temperature can also be baked.
A vent pipe may be connected to the steam reservoir in the upper space of the boiler separately from the steam pipe, and an adjusting valve may be provided on the vent pipe so that the amount and pressure of steam supplied to the kettle can be adjusted. .
For the purpose of attracting the attention of customers, a whistle or the like capable of blowing sound with steam is provided at the end of a vent pipe provided for adjusting steam pressure, and the strength or length of the sound is controlled by operating a valve for adjusting steam pressure. It may be controlled.
One end of the water supply pipe is connected to the boiler near the bottom of the boiler, and the height of the water supply port provided at the other end of the water supply pipe is set so as to leave an appropriate amount of space for the steam reservoir in the boiler. When the water level in the boiler is higher than the upper limit water level, water is allowed to overflow from the water inlet, and the water level in the boiler rises due to expansion or steam pressure in the boiler and passes through the steam pipe. It is recommended to prevent water from squirting into the kettle.
The apparatus can be mounted on a car, a rear car, or the like by bringing water and fuel together, or can be moved by towing the car, the rear car, or the like.
