2. Description of the Related Art Pottery is placed on a wire net and baked by open flame or open flame. In particular, seafood and meat with relatively high water content are baked over high heat so as not to lose water and become hard. However, in this case, because it is open to the atmosphere,
Since the temperature of the atmosphere is low and the internal core temperature of the object to be heated is hard to rise, a long time is required for the ware. As described above, since it takes a relatively long time to make a pottery, there are problems such as, when there are a large number of food and beverages, serving as an order or having the food and beverages wait. However, even if the baked goods are prepared in advance, there is a problem that the cook is cut off for a long time during the baking.

[0003] Even if meat and seafood are baked continuously,
When baking meat and seafood, since the gravy drops, the heating device cannot be placed directly below the object to be heated, and only the upper side is a problem. Therefore, a heating device is provided above and below, so that meat or seafood is put in a metal or enamel container so that the gravy does not drip, the container containing the meat or seafood is blown with hot air or far infrared rays. There is proposed an apparatus formed so that meat or fish and shellfish in a container are continuously grilled by passing through a space irradiated with water.
An object of the present invention is to solve such a problem, particularly in a conventional grilled product for meat or seafood.
