Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for baking food in the field of food processing. Especially when baking food, in a short time,
The present invention relates to a device for baking food that evenly penetrates into the interior of the food and fully brings out the original umami of the food without completely losing the color inherent in the food.

[0002]

2. Description of the Related Art Conventionally, when baking foods such as fish, sweet potatoes, and bread, baking is performed by using a device for directly heating with gas or an electric heater, that is, an oven, a microwave oven, a toaster, a stove, or the like. However, although the surface of the food was well cooked, and the inside of the food was not yet well-burned in many cases, although it was burnt. In particular, foods with a small surface area and a large volume require a long time to cook through the fire to the inside, during which many of the scents of foods, juices with more water and umami than necessary evaporate, It was very difficult to bake while keeping the original umami of food by separating it from food. In order to cook without losing these scents and umami, food is also wrapped in aluminum foil or the like and baked, but this is different from the device of the present invention in the field of boiling or steaming with the moisture of the food. To do.

[0003] Further, as is seen in general stone-baking potato-baking equipment and wire-nets with ceramics for baking fish, stones and ceramics plates are heated and baked without directly heating food. (For example, JP-A-1-12101
8, JP-A-1-55851, JP-A-3-41631). This is devised on the device for the purpose of uniformly heating the inside of the food, but in these cases, it takes a long time to completely cook because the food is heated from only one direction. It takes time and is still insufficient to bring out the full umami as shown above. In addition, when fish is baked, it is difficult to remove it due to the smell attached to the container and its surroundings.
There was a problem with the smell of the food to be cooked next.

[0004]

DISCLOSURE OF INVENTION Problems to be Solved by the Invention As a result of intensive studies aimed at eliminating these problems, the present invention encloses a layer of stones containing at least 30% of bakuhanishi from at least two directions of food, and heats it from the outside. It has arrived at a food baking device characterized by: This device can even bake food from the outside to the inside in a short time, so that it has a small surface area and a large volume, such as sweet potatoes, roasted chicken, lumps of meat, and fish. It can be baked uniformly and in a short period of time without any hardening or carbonization. Therefore, it has the feature that it retains the unique color of food and can be cooked without impairing the umami of food. In addition, it is also a great feature that the function of adsorbing and removing the malodor inherent in bakuhanishi leaves almost no odor in the container after baking the food.

[0005]

[Means for Solving the Problems] The present invention is characterized in that instead of directly heating food, a layer of stone containing 30% or more of barley stone is heated and the food is baked by heat emitted from the layer of stone or far infrared rays. It is what The food cooked in the present invention may be any food that is generally baked and cooked, and is not particularly limited. Specifically, this includes fish such as horse mackerel and swordfish, dried fish that has been dried or dried overnight, potatoes such as sweet potato, bread, bread, and other rice cakes and fruits, especially chestnuts and apples.

The barley stone used in the present invention is an igneous rock that is mined mainly in Liaoning and Jilin provinces of China, and is part of Gifu prefecture in Japan, and is a kind of quartz stone. The component is an ore mainly composed of anhydrous silicic acid, but it contains many components such as iron, sodium, potassium, magnesium, calcium, etc., and when it is immersed in water, various minerals beneficial to the human body are eluted, so it has been old in China. It has been used as a medicinal stone. Also, this barley stone is a porous substance, a harmful substance in water,
For example, it also has a function of adsorbing harmful metal ions such as mercury and arsenic, malodor, chlorine and other harmful organic substances, and has been used as a purifier for tap water, a purifier for bath water, and an apparatus for producing mineral water. There are also reports that feed it to cattle to keep it healthy, or put it in farmland to activate the soil. However, there is no report that the device is used for baking foods through the barley stone as in the present invention.

When food is baked through this barley stone, the inside of the food can be cooked uniformly and in a short time because of other ordinary stones, ceramics, and ceramics that are said to emit far infrared rays. The reason for this is not clear, but it is considered that boiled stone receives heat from the outside and has a mechanism that heats food by converting it to far infrared rays, and the conversion efficiency from this heat to far infrared rays is very large. It is estimated to be. It is necessary that the stone layer composed of this barley stone contains at least 30% or more of barley stone. It is particularly preferably 50% or more, further preferably 70% or more. If it is less than 30%, the characteristic of the present invention that baking is performed uniformly and in a short time is lost, which is not preferable. What can be blended other than barley stone,
Any mineral may be used as long as it is a mineral such as general crushed stone, sand, alumina, other ceramics, and ceramics that emit far infrared rays. The shape of the stone containing 30% or more of bakuhanite is not particularly limited, but the average particle size is
Containers of various shapes such as plates and various shapes obtained by heating powders of 50 μm to several centimeters to sand, pebble solids, or bakehanishi powders with a clay-based binder that can be thermally caking. Or a plate can be used. The thickness of these layers is not particularly limited as long as the heat from the outside does not directly reach the food, but is usually 1 mm to 10 c.
m, preferably 0.5 mm to 5 cm.

It is necessary that the stone layer composed of the barley stone surrounds the food from at least two directions. The two or more directions include all directions other than the case where only one direction such as top, bottom, and side is installed. Specifically, it may enclose the horizontal two directions, the upper and lower two directions, and the lateral perimeter of the cylindrical container, or may enclose the vertical, left and right three directions, or all four sides of the food. Also, in special cases, to make it easier to take out food, it is not placed vertically or laterally in parallel, but at an angle, or in two or more directions on the wall surface of irregularly shaped containers such as circles, ellipses, and cylinders. It can also be installed at. When heating from only one direction, the above effects of the present invention cannot be sufficiently exhibited, which is not preferable.

As a method for heating bakuhanishi from the outside, an electric heater or gas is usually used. This heating part does not have to be in two or more directions in particular, and one heating part only needs to sufficiently heat the layer made of barley stone in two or more directions.
Further, as a method for heating the layer made of barley stone, a method of heating with a heater, a method of heating by winding an electric heater around the layer made of barley stone, a method of spraying with a gas burner from the outside of the layer of barley stone, etc. Various methods are taken. When using a small apparatus, heating with an electric heater is preferable.

The food baking apparatus of the present invention includes a layer composed of barley stone from at least two directions of the food,
Any device may be used as long as it is a device that heats from the outside. Although the present invention is not limited to the device described below, for example, it is surrounded by a layer made of barley stone from above and below or from the left and right, and a device for grilling fish by heating with a gas burner or an electric heater from the outside, a diameter of 6 to 8 cm Make a 20 cm deep cylindrical hole with a layer of 1 to 2 cm thick boiled stone around it and wind the outside with an electric heater, put food such as sweet potato in the hole and use an electric heater with a timer A device for heating for a certain period of time, as shown in FIG. 1, two holes for baking this food are installed, the holes are arranged in parallel, and a space between them is 2c
It is connected by a groove of m, and a grid-shaped frame having a width of 2 cm is formed around the groove, and filled with barley stone adjusted to have a diameter of 0.5 to 2 cm. A 1 kW electric heater is wound on the outside of this layer and connected to a timer. The bottom of this hole was a stainless steel plate that was pulled down when food was put in, like a toaster for baking bread, and was set so that it automatically rose with a spring when a predetermined time came. This outside is a device for baking small baked potatoes and bread, which is surrounded by a metal box whose entire surface except the upper side is covered with a heat insulating material.

It was connected by a groove of m. A grid-like frame (1) having a width of 2 cm was formed around the side of the frame, and the barley stone (2) adjusted to have a diameter of 0.5 to 2 cm was filled therein. An electric heater (3) of 1 kW was wound on the outside of this layer of boiled stone and connected to a timer (4). The bottom of this hole was a stainless steel plate, which was pulled down when food was added like a toaster for baking bread, and was set so that it was lifted by a spring when a predetermined time came (5). This outside was covered with a heat insulating material except the upper side and surrounded by a metal box. Prepare two sweet potatoes with a length of 18 cm and a diameter of 5 cm, and use the two cylindrical holes (6) of the above device.
And heated for 20 minutes. The surface of the burnt sweet potato was a little scorched, and the inside was well cooked while leaving the reddish color of the sweet potato.

COMPARATIVE EXAMPLE 1 The apparatus for directly heating the food in the inside with the outside heater was used without filling the frame in which the barley stone of Example 1 was filled. Sweet potatoes of the same size as in Example 1 were heated for 20 minutes as in Example 1. The surface of the obtained roasted potatoes was charred and fully baked, but the central portion was still boiled. Three
Even if it was heated for 0 minutes, the outside was severely burnt, but the center was not yet sufficiently burnt.

Comparative Example 2 With Example 1 except that the apparatus of Example 1 was filled with quartz rock adjusted to a size of 0.5 to 2 cm instead of barley stone in the frame containing the barley stone. A similar device was created. Example 1
Put sweet potatoes of the same size used in
Heated for minutes. The burnt sweet potato was burnt on the outside as in Example 1, but the central portion of the potato was not cooked sufficiently. In addition, when the heating time was set to 30 minutes, it was burned to the center, but the outside was scorched or terrible, and the water content of the potatoes was considerably evaporated and the taste was considerably deteriorated.

Example 2 60 parts of bakuhanishi crushed to a size of 100 μm to 1 mm, 40 parts of clay as a caking binder and an appropriate amount of water were sufficiently kneaded, molded and dried, and then heated at 1200 ° C. It was put in a furnace and baked for 12 hours to obtain a plate having a thickness of 7 mm and containing barley stone. Put the plate containing the above boiled rice stones above and below the electric oven,
An electric heater was installed from the outside so that the electric heater did not directly hit the food. A horse mackerel having a length of 20 cm was placed in the middle of the oven and heated from above and below through a board of boiled stone. The salted roasted mackerel obtained in 20 minutes of baking time had a slightly scorched surface, and the inside was well cooked, which was delicious. The oven after baking was good, with almost no fish odor.

Comparative Example 3 A conventional oven in which food was directly baked with an electric heater was put in the apparatus of Example 2 without the plate containing barley stone. A horse mackerel of the same size as that of Example 2 was put in this, baked for 20 minutes, and then taken out. However, although the surface was considerably charred, the inside was not sufficiently cooked. Also, the oven after baking had the smell of fish and could not be separated.

Example 3 The porcelain plate obtained in Example 2 was 20 cm long and 1 to 3 cm wide.
Cut into pieces, put in a frame filled with barley stone of the apparatus of Example 1 so that there is no gap instead of barley stone, and baked sweet potatoes in the same manner as in Example 1 It was cooked and delicious.
