Description

【0001】
【発明の属する技術分野】
本発明は、春巻の皮、クレープシート等の薄皮焼成食品の製造方法に関する。
【0002】
【従来の技術】
従来、この種の薄皮焼成食品は、ドラム外周面が内蔵ヒータにより所望の温度に加熱された焼成ドラムを低速回転させ、この焼成ドラムの外周面に対向して焼成ドラムの長軸方向に沿って開口するスリット状ノズルからペースト状生地を焼成ドラムの外周面に薄皮状に付着させて焼成することによって製造されていた。このような従来方法で充分な焼成を行うためには、焼成ドラムの外周面に長時間に亘りペースト状生地を付着させておく必要がある。そのために例えば直径2メートルの焼成ドラムを使用したり、焼成ドラムを極めてゆっくり回転させる等の必要があった。
【0003】
【発明が解決しようとする課題】
しかしながら、直径の大きい焼成ドラムを用いるために装置が大型化し、広い設置場所が必要となるばかりでなく、製品製造の切り替え時に焼成ドラム面に残留する半製品生地が多くなる欠点があった。また装置を小型化するために、焼成ドラムの直径を小さくしてゆっくり回転させた場合生産性が低下するばかりでなく、ペースト状生地を焼成ドラムの外周面に薄皮状に均一に付着させることができないという欠点があった。
そこで、本発明者等は、前記のような問題点に鑑み、小型の回転ドラム焼成装置によっても品質の安定した薄皮焼成食品を効率よく製造する方法について鋭意研究した結果本発明を完成するに至った。
【0004】
【課題を解決するための手段】
すなわち、本発明は、加熱された焼成ドラムの外周面に、ペースト状生地を薄皮状に付着させて焼成する薄皮焼成食品の製造法において、前記焼成ドラム外周面における薄皮状生地が、流動性を失う部位から焼き色が生ずる部位までの間で薄皮状生地表面に空気を吹付けることを特徴とする薄皮焼成食品の製造方法である。
【0005】
【発明の実施の形態】
次に本発明を図面を参照しながら説明するが、本発明は、以下の説明のみに限定されるものではない。
図1は、本発明の薄皮焼成食品を製造するための回転ドラム焼成装置の一例を示した概略的な側面図である。軸着されたヒータを内蔵する焼成ドラム1の外周面の下部に、ホッパ2からパイプ3を介して扇状に広がったスリット状ノズル4を設ける。スリット状ノズル4の吐出口5の幅員は、焼成ドラム1の長軸方向の幅員よりやや狭い幅員とすることが好ましい。
またスリット状ノズル4の吐出口5は、吐出するペースト状生地が焼成ドラム1の回転方向に向けて吐出するように設けることが好ましい。さらに他の態様として、図2に示すようにスリット状ノズル4を略水平に設ける場合は、吐出口5を斜めにカットして吐出口5の下部吐出縁より上部吐出縁を短くした形状とすることによって、吐出口5からのペースト状生地の垂れがなくなるので好ましい。
【0006】
焼成ドラム1の直径は0.3〜0.7メートル、特に0.4〜0.6メートルの範囲のものが好ましい。焼成ドラム1の周速は、焼成ドラム1の温度および焼成ドラム1の外周面に形成されたペースト状生地の厚さによっても異なるが、通常3〜5cm/secの範囲が好ましい。
【0007】
また回転ドラム焼成装置には、焼成ドラム1の外周面に対向し、かつ焼成ドラム1の長軸方向にスリット状に開口した空気吹付け装置6を設ける。この空気吹付け装置6を設ける位置は、焼成ドラム1の外周面に付着した薄皮状生地7が流動性を失う部位から薄皮状生地7に焼き色が生ずる間に設けることが好ましい。すなわち、この設置位置としては、焼成ドラム1の周速、ペースト状生地の水分含量および薄皮状生地の厚さによっも異なるが、一般的にはスリット状ノズル4の吐出部5の上部の近傍から、焼成ドラム1の軸を通る鉛直線と、上部外周面が交わる点Pまでの範囲が好ましい。
【0008】
また空気吹付け装置6から送風する空気は、20〜60℃の温度のものが好ましく、風速も0.5〜15.0m/secの範囲が好ましい。この風速が0.5m/secより弱いと薄皮状生地からの水分の除去が充分に行われず、一方15.0m/secより強くなると、薄皮状生地の厚みにむらができたり、焼成ドラム1の外周面から剥離するようになる。
【0009】
また焼成装置の焼成ドラム1には薄皮焼成食品を剥離するためのスクレーパ8が設けられている。焼成ドラム1からスクレーパ8によって剥離された薄皮焼成食品はコンベア9により、所望の形状にカットするための成形工程に搬送し、製品とする。
【0010】
【実施例】
次に本発明の薄皮焼成食品の製造例について説明する。
ホッパ2のペースト状生地を圧送ポンプ(図示せず)によってパイプ3を介してスリット状ノズル4から回転している焼成ドラム(直径0.5m,1.5r.p.m)の外周面に薄皮状に付着させる。焼成ドラム1は、内蔵しているヒータ(図示せず)によって加熱されているため、焼成ドラム1の外周面に付着した薄皮状生地7は水分が蒸散して除去されることによって流動性を失い、焼成ドラム1の外周面に密着した状態で焼成ドラム1と共に回動する。
【0011】
流動性を失った薄皮状生地7は、次に空気吹付け装置6から空気(60℃)を5.0m/secの風速で吹付け、薄皮状生地7から水分を蒸散させる。水分が少なくなった薄皮状生地7は、さらに焼成ドラム1と共に回動して加熱された後焼成ドラム1に設けられたスクレーパ8によって焼成ドラム1の外周面から剥離される。
剥離された薄皮状生地7は、ベルトコンベア9によって裁断(成形)工程に搬送され、ここで所望の形状に整えられて薄皮焼成食品が得られる。
【0012】
【発明の効果】
本発明方法によれば、春巻の皮、揚げ餃子の皮、洋菓子用のクレープ、おかき、ポテトチップ等の薄皮焼成食品を効率よく製造することができる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a method for producing a skin-baked food such as spring roll skin or crepe sheet.
[0002]
[Prior art]
Conventionally, this type of skin-baked food is produced by rotating a baking drum whose outer peripheral surface is heated to a desired temperature by a built-in heater at a low speed, and facing the outer peripheral surface of the baking drum along a longitudinal direction of the baking drum. It has been manufactured by attaching a paste-like dough to the outer peripheral surface of a baking drum in the form of a skin from a slit-shaped nozzle that opens, and baking it. In order to perform sufficient baking by such a conventional method, it is necessary to keep the paste-like dough adhered to the outer peripheral surface of the baking drum for a long time. For this purpose, for example, it was necessary to use a firing drum having a diameter of 2 meters or to rotate the firing drum extremely slowly.
[0003]
[Problems to be solved by the invention]
However, the use of a baking drum having a large diameter increases the size of the apparatus, requires a large installation space, and has the disadvantage that semi-finished dough that remains on the baking drum surface during switching of product production increases. In addition, if the diameter of the baking drum is reduced and rotated slowly in order to reduce the size of the apparatus, not only does the productivity decrease, but also the paste-like dough can be uniformly adhered in a thin skin shape on the outer peripheral surface of the baking drum. There was a disadvantage that it could not be done.
In view of the above problems, the present inventors have conducted intensive research on a method for efficiently producing thin-skin baked foods of stable quality even with a small rotary drum baking apparatus, and have completed the present invention. Was.
[0004]
[Means for Solving the Problems]
That is, the present invention relates to a method for producing a thin-skin baked food in which a paste-like dough is adhered in a thin-skin shape on the outer peripheral surface of a heated sintering drum, and baked. A method for producing a skin-baked food, characterized in that air is blown onto the surface of the skin-like dough from a part where the skin is lost to a part where the browning occurs.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, the present invention will be described with reference to the drawings, but the present invention is not limited only to the following description.
FIG. 1 is a schematic side view showing an example of a rotating drum baking apparatus for producing the thin-skin baking food of the present invention. At the lower part of the outer peripheral surface of the firing drum 1 having a built-in heater attached thereto, a slit-shaped nozzle 4 is fan-shapedly spread from a hopper 2 via a pipe 3. It is preferable that the width of the discharge port 5 of the slit nozzle 4 is slightly smaller than the width of the firing drum 1 in the long axis direction.
Further, the discharge port 5 of the slit nozzle 4 is preferably provided so that the paste-like material to be discharged is discharged in the rotation direction of the baking drum 1. As yet another embodiment, when the slit-shaped nozzle 4 is provided substantially horizontally as shown in FIG. 2, the discharge port 5 is cut obliquely so that the upper discharge edge is shorter than the lower discharge edge of the discharge port 5. This is preferable because the paste-like dough does not hang from the discharge port 5.
[0006]
The diameter of the firing drum 1 is preferably in the range of 0.3 to 0.7 meters, particularly 0.4 to 0.6 meters. The peripheral speed of the baking drum 1 varies depending on the temperature of the baking drum 1 and the thickness of the pasty dough formed on the outer peripheral surface of the baking drum 1, but is preferably in the range of usually 3 to 5 cm / sec.
[0007]
In addition, the rotary drum baking device is provided with an air blowing device 6 which faces the outer peripheral surface of the baking drum 1 and is opened in a slit shape in the longitudinal direction of the baking drum 1. It is preferable that the air blowing device 6 is provided while the thin-skin material 7 attached to the outer peripheral surface of the baking drum 1 loses its fluidity and the thin-skin material 7 is baked. That is, the installation position varies depending on the peripheral speed of the baking drum 1, the moisture content of the paste-like dough, and the thickness of the skin-like dough. To the point P where the vertical line passing through the axis of the firing drum 1 intersects the upper outer peripheral surface.
[0008]
The air blown from the air blowing device 6 preferably has a temperature of 20 to 60 ° C., and the wind speed is preferably in a range of 0.5 to 15.0 m / sec. If the wind speed is lower than 0.5 m / sec, moisture is not sufficiently removed from the skin-like dough. If the wind speed is higher than 15.0 m / sec, the thickness of the skin-like dough may be uneven or the baking drum 1 It comes off from the outer peripheral surface.
[0009]
The baking drum 1 of the baking device is provided with a scraper 8 for peeling the skin-baked food. The thin-skin baked food peeled off from the sintering drum 1 by the scraper 8 is conveyed by the conveyor 9 to a molding step for cutting into a desired shape, and is made into a product.
[0010]
【Example】
Next, a production example of the baked thin skin food of the present invention will be described.
The paste-like dough of the hopper 2 is thinned on the outer peripheral surface of a baking drum (diameter 0.5 m, 1.5 rpm) rotated from a slit nozzle 4 through a pipe 3 by a pressure pump (not shown). To adhere. Since the baking drum 1 is heated by a built-in heater (not shown), the skin-like dough 7 adhered to the outer peripheral surface of the baking drum 1 loses fluidity due to evaporation of water and removal. Then, it rotates together with the firing drum 1 in a state of being in close contact with the outer peripheral surface of the firing drum 1.
[0011]
The skin-like dough 7 that has lost fluidity is then blown with air (60 ° C.) at a wind speed of 5.0 m / sec from an air blowing device 6 to evaporate moisture from the skin-like dough 7. The skinned dough 7 having reduced moisture is further rotated and heated together with the baking drum 1 and then peeled off from the outer peripheral surface of the baking drum 1 by a scraper 8 provided in the baking drum 1.
The peeled skin-like dough 7 is conveyed to a cutting (molding) step by a belt conveyor 9, where it is adjusted to a desired shape to obtain a skin-baked food.
[0012]
【The invention's effect】
According to the method of the present invention, thin-shelled baked foods such as spring roll skin, fried dumpling skin, crepe for western confectionery, oysters, and potato chips can be efficiently produced.
