Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking apparatus for pottery, and more particularly to an apparatus for cooking foods such as seafood and vegetables using a large amount of radiant heat.

[0002]

2. Description of the Related Art In general, a yakitori shop eel shop burns charcoal as a fuel in a horizontally long cooking furnace having an open upper surface, and places a gold skewer or bamboo on a plurality of support rods arranged at the top of the cooking furnace. Place on the skewers meat such as poultry and pork, or skewers stabbed with vegetables such as green onions, peppers and eggplants, or separately, and heat them to produce yakitori, or similarly grill eel. Are doing.

[0003]

Charcoal is generally used in this kind of cooking furnace for pottery. Among them, Bincho charcoal is used as a hard and high-grade fuel. This hard charcoal has a strong firepower, a long burning time, and a good shape retention of the burning charcoal, so it has a good air supply, stable firepower, and burns at a high temperature for a relatively long time. It is excellent in that it is relatively easy. However, when using this cooking furnace, it is necessary to prepare a cooking furnace that can ignite the charcoal in advance before the customer enters the store and immediately cook at the same time as the customer enters the store. The most important point when using this cooking device is that while controlling the amount of high-temperature combustion gas rising from below the cooking furnace, a large amount of radiant heat radiated from red-hot charcoal can be It is the skill of the cooker how to supply the processed food product in an efficient and constant state.

If the whole food is heated while surrounding the food to be processed with high-temperature combustion gas and a large amount of radiant heat is further applied from below, the amount of heat received by the food to be processed becomes excessively large compared to the cooking speed. A large amount of meat juice oozes from inside while the surface is burnt. Excessive scraping of the surface in this way reduces the value of the baked goods and causes the meat to tighten and harden with the leaching of the gravy. Naturally, when the gravy oozes out, the nutrients of the meat are released in vain, and the taste drops with it. Further, as described above, while the meat is hardened as a whole, the size of the whole meat is reduced and the appearance is deteriorated.

As described above, when cooking yakitori or the like using charcoal as a heat source, it is necessary to remove the high-temperature combustion gas using a pouch or a fan so that the high-temperature combustion gas is not applied to the processed food as much as possible. There is. In order to heat the processed food uniformly, the skewers often need to be inverted depending on the degree of burning. In the case of charcoal using charcoal as described above, first, it is necessary to constantly control the heating and burning of charcoal.Secondly, in order to eliminate high-temperature combustion gas and use radiant heat effectively, always use a fan. It is necessary to prevent the food from being heated at high temperatures. Thirdly, the skewers must always be inverted so that the processed food is evenly cooked on both sides.

[0006] Such a series of complicated operations is something that a cook with long-term experience and excellent intuition can learn,
It is not a technology that can be achieved for cooks who have just started their work. Therefore, if you are a cook with abundant experience cooking at famous shops, the meat is relatively soft, the outer shape is less deformed, the amount of juice leaching is less, and the appearance is more appropriate It can be made to taste good, which is significantly different from baked goods cooked by inexperienced people.

There is another major problem with cooking charcoal using charcoal. That is, the cooking time is long in addition to the above-mentioned problems requiring advanced techniques such as heat control and roast control. In particular, it takes a long time for high-class dishes such as salted grilled sea bream or grilled eel, which makes it difficult to cook wares in a short time. As a heating means, there is a method using gas as fuel or a method using electric heat.However, in the method using gas, since the high-temperature combustion gas directly wraps the food to be processed, the surface is exposed to high temperature and burnt. In addition to the fact that it easily exudes a large amount of gravy in a short time, the taste is significantly impaired. Then, the meat shrinks greatly with the exudation of the broth, becomes hard and loses the texture together with the taste. For this reason, gas-fired cooking has only a limited range.

[0008] On the other hand, electric heat is often used particularly for home cooking devices, but generally has a small calorific value and cannot be cooked at all for large processed foods requiring a large amount of heat. In addition, since it is difficult to heat the workpiece to a high temperature by this electric heating method, it is difficult to produce a delicious grilled dish like a charcoal fire. SUMMARY OF THE INVENTION The present invention provides a cooking apparatus for grilling which can substantially eliminate the drawbacks of the conventional grilling dishes using charcoal, the grilling dishes using gas, and the grilling dishes using electricity.
