Description

  The present invention relates to a food baking device, and more particularly to a food baking device that can bake food well in a short time regardless of the skill of the cook.

  Conventionally, grilled skewers such as yakitori are baked over charcoal. However, in this charcoal grill, it was difficult for an amateur to bake deliciously and nicely because of the large temperature variation. In addition, ignition, extinguishing of charcoal, storage after extinguishing, and the like are complicated. Furthermore, in the case of using cheap saw charcoal obtained by hardening sawdust with tar instead of expensive bincho charcoal, a tar odor is attached to the food.

Therefore, in order to solve the above problem, as a conventional food baking device, a wire net 18 on which a far-infrared radiation material 20 is placed is disposed above the heat source 14, and the skewered food material 12 is baked by the radiation of far-infrared radiation. Is known (see, for example, Patent Document 1).
However, in Patent Document 1, the flame of the heat source 14 passes through the gap between the wire mesh 18 and the far-infrared radiation material 20, and the flame may ignite the oil of the food material and burn the surface of the food material 12. is there. On the other hand, if the heating power of the heat source 14 is weakened to prevent the food from being burnt, the baking time of the food becomes longer.

According to the food baking apparatus of the present invention, the flame from the combustion means is blocked from flowing toward the food by the flame shielding means. On the other hand, the hot air from the combustion means flows through the hot air flow passage through the lower slit of the flame shield means and flows from the upper slit to the food side. And while the hot air heats a foodstuff through the clearance gap between far-infrared ray generation members, a far-infrared ray generation member is heated with the hot air, and a far infrared ray is generated. As a result, in addition to heating the food by hot air, the food can be baked well in a short time by the far infrared rays from the far infrared ray generating member.

1. Food baking apparatus The food baking apparatus according to the present embodiment includes combustion means, flame shielding means, storage means, and placement means described below. This food baking machine can further include, for example, a support frame described later.
The type of the “food” is not particularly limited, but is preferably a skewered food prepared by skewing meat, seafood, vegetables and the like.

The “combustion means” is not particularly limited in its structure, combustion mode and the like as long as fuel is combusted.
Examples of the combustion means include a burner, a stove, a heater, and charcoal fire. Of these, a burner (particularly, a gas burner) is preferable from the viewpoint that it can be configured more simply and inexpensively.

  As long as the “flame shielding means” is provided above the combustion means and blocks the flame from the combustion means, its structure, flame shielding form, etc. are not particularly limited. This flame shield means has a hot air flow passage and upper and lower slits described below.

The “hot air passage” is not particularly limited in structure, shape, installation form, or the like as long as it is a passage for circulating hot air from the combustion means.
Examples of the hot air flow passage include (1) a plurality of parallel main passages and a plurality of communication passages that connect adjacent main passages, and (2) a plurality of concentric main passages. , A form consisting of a plurality of communication passages that connect adjacent main passages, (3) a form consisting of a bellows-like main passage and a communication passage that connects adjacent parts of the main passage, etc. Can be mentioned. Among these, from the viewpoint that hot air can be circulated more evenly over the entire plane of the flame shield means, the form (1) is preferred.

The “upper and lower slits” are not particularly limited in structure, shape, installation form, or the like as long as they are connected to the hot air flow passage and open in the horizontal direction.
For example, a plurality of the upper and lower slits may be provided at predetermined intervals along the longitudinal direction of the main passage.

Here, the flame shield means has, for example, upper and lower plates that are overlapped with each other, and these upper and lower plates have upper and lower flow passage forming portions that form the hot air flow passages in the superposed state. The upper and lower slits can be formed in the upper and lower flow passage forming portions.
In the case described above, the upper and lower slits can be formed at the base of the upper and lower flow passage forming portions, for example. Thereby, while being able to suppress a flame | frame invasion to a lower slit more reliably, hot air can be more smoothly passed through an upper and lower slit.
Although the cross-sectional shape of the said hot air flow path is not specifically limited, It can be made into a hexagon, a triangle, or a rectangle. In particular, in the case of this triangle, since it can be produced using an L-shaped angle, the blocking means can be configured more simply and inexpensively.

As long as the “accommodating means” is provided above the flame shield means and accommodates the far-infrared ray generating member, its structure, accommodation form, etc. are not particularly limited.
The accommodating means can have, for example, a bottom wall portion and a peripheral wall portion that rises from the periphery of the bottom wall portion. This bottom wall part can be comprised by the said flame-shielding means, for example.

As long as the “far-infrared ray generating member” generates far-infrared rays by heating, its shape, material, amount of use, etc. are not particularly limited.
Examples of the far infrared ray generating member include ceramics, stone, alumina, titania and the like.

The far infrared ray generating member can be, for example, a ceramic chip made of carbide. This ceramic chip can be obtained, for example, by mixing a binder (clay or the like) with the powdered carbonite and sintering the mixture.
In the case described above, the ceramic chip preferably has a cylindrical shape with a diameter of 8 to 12 mm. This is because if the diameter is less than 8 mm, the gap between the ceramic chips becomes small and the air permeability becomes low, and if the diameter exceeds 12 mm, the gap between the ceramic chips becomes large and the flame may pass through.

As long as the “placement means” is provided above the accommodation means and the food is placed, the structure, the form of placement, etc. are not particularly limited.
Examples of the placing means include a placing table, a wire mesh, a frame member, and a holed iron plate.
The above-mentioned placing means can be detachably provided on the upper part of the housing means, for example.

As long as the “support frame” supports the combustion means, the flame shield means, the housing means, and the placement means, the structure, the support form, etc. are not particularly limited.
For example, the receiving means can be detachably provided on the support frame.
The support frame may have, for example, a skirt that surrounds the lower periphery of the flame shield means. Thereby, the hot air from the said combustion means can be efficiently distribute | circulated to the hot air flow path of a flame shield means. Therefore, the high temperature (about 500 to 550 ° C.) that is the life of the skewer is obtained.
