Description

  The present invention relates to a food container for heating directly under which food such as dumplings can be baked satisfactorily.

  2. Description of the Related Art Conventionally, it has been widely practiced to prepare cooked or uncooked food in a heatable container to form a food package. Such a food package can be heated by a consumer at home or the like. Thus, the food and drink can be made available.

  Techniques relating to such food packaging bodies have been widely proposed. For example, as a method of solidifying soup stock or soup and placing udon and ingredients on top of the solid soup, a “method for producing pot-baked udon” (Patent Document 1) Reference), “packaged food” (see Patent Document 2), “food with frozen soup” (see Patent Document 3), “instant food in a heating container” (see Patent Document 4), and the like have been proposed. In addition, as a cooked food in which a concentrated seasoning liquid gelled on a main ingredient is placed on top and water is added when heated immediately below, “cooked food stored in a directly heated container” (see Patent Document 5) ) Etc. have been proposed.

  In addition, as a food and oil aggregate solid and a food in a baking container, a method for producing popcorn (see Patent Documents 6 and 7) and a “frozen food in a baking container and its manufacturing method” (see Patent Document 8) are proposed. Has been.

Japanese Patent Laid-Open No. 51-112540 Japanese Patent Laid-Open No. 2-60579 Japanese Utility Model Publication No. 5-31592 Japanese Patent Laid-Open No. 9-47266 JP-A-6-46804 Japanese Examined Patent Publication No. 37-1656 Japanese Utility Model Publication No. 49-42696 JP 61-132170 A

  However, in the conventional technology described above, dumplings and the like could not be fired well.

  That is, the techniques proposed in Patent Documents 1 to 5 are mixed with udon, ingredients, or main ingredients by heating or liquefying soup or soup that has been solidified or solidified, and is heated by direct heating. Since it is a method of warming food, the food cannot be baked, and the main ingredients and components also flow into liquids such as soup and soup.

  The techniques proposed in Patent Documents 6 to 8 are methods for heating and baking foods by mixing dried foods with a low water content and fresh foods with high water content but small fats with oils and fats, putting them in containers, and heating them directly. As a result, unheated parts are generated for foods with a high moisture content such as cooked foods, and the contact surface with the tray may be burnt if sufficient heating is performed. It was.

  In addition, it is possible to bake after steaming by mixing food and liquid in a container consisting of an aluminum tray, etc., and then heating directly under the lid. Will fall. In addition, in the baking process after the components of the food flow out into the liquid and the liquid evaporates, the outflow adheres to the surface of the tray and burns, resulting in a burnt smell. In addition, the tray is not preferable because it looks black.

  The present invention solves the above-described problems, and allows the food to be sufficiently baked without burning even when subjected to a direct fire such as a grill or heated by electromagnetic induction (IH). An object is to provide a food container for heating.

  The inventors of the present invention diligently studied to achieve the above-described object, and provided a storage unit storing water or the like and a storage unit storing food to be baked in a horizontal direction by partitioning in a vertical direction, The present invention has been completed by finding that heating and water together with food can prevent uneven heating of the food container and adjust the baking time of the food container.

  That is, the inventors first made an iron frying pan (melting point: 1530 ° C., thermal conductivity: 99, thickness: 1 mm) and an aluminum tray (melting point: 660 ° C., thermal conductivity: 241; thickness: 70 μm). We examined the difference in heat transmission. An iron frying pan and an aluminum tray were lit directly without any heat, and the heat distribution was examined by thermography. FIG. 10 shows a thermography of an iron frying pan, and FIG. 11 shows a thermography of an aluminum tray.

  As a result, it was found that the aluminum tray was heated more unevenly than the iron frying pan and was heated locally. Despite the better thermal conductivity of the aluminum tray, the cause of uneven heating is that the aluminum tray has a low melting point and is thin. It is thought that is taken away by. In fact, the aluminum tray was melting.

  Next, the heat distribution when the aluminum tray was filled with water was examined. The aluminum tray filled with water was directly lit and the heat distribution was examined by thermography. FIG. 12 shows the thermography of the aluminum tray in which water remains, and FIG. 13 shows the thermography of the aluminum tray after the water has evaporated.

  As a result, it was found that while the water remained, it was heated evenly at 100 ° C. or less, but at the same time, local heating started. Therefore, it has been devised that the presence of water can prevent the aluminum tray from being locally heated and melted, and the heating time can be adjusted by the amount of water (that is, the time until the water evaporates).

  Furthermore, the heat distribution when oil was applied to the aluminum tray was examined. Oil was applied to half of the aluminum tray and lit directly, and thermography examined how the oil affected the heat distribution. FIG. 14 shows a thermography immediately after being lit.

  As a result, it was found that the temperature of the half with oil applied increased uniformly and rapidly. Therefore, it was confirmed that the food can be heated uniformly and in a short time at a high temperature by heating the food after drawing the oil. However, overheating occurred in a short time, and ignition or burning of the tray occurred.

  The food container for direct heating according to the present invention has been completed based on the knowledge obtained as a result of the above examination, and is provided adjacent to the food container in which the solid food is stored and the food container in the horizontal direction. A liquid storage portion for storing the liquid, the food storage portion and the liquid storage portion are formed of a material that can be heated directly below, and a lid that covers the food storage portion and the liquid storage portion is provided. It is configured as a feature.

  In the food container for direct heating according to the present invention, the liquid container and the food container are heated at the same time so that there is a lid, so that the food on the container contact surface of the food container is baked and steamed by the steam of the liquid container. Heating can be performed at the same time, and as a result, food can be baked and heated well in a short time.

  The food container for heating directly under the present invention has a food container for storing solid food, and a liquid container for storing liquid provided adjacent to the food container in the horizontal direction, The heating of the food storage unit can be adjusted by the liquid stored in the liquid storage unit, and the size of the liquid storage unit is appropriately changed according to the size of the food, the heating temperature, etc. About twice is preferable. Moreover, in a general household gas range, it is preferable to provide a liquid container around the food container. By providing the liquid container around the food container, the temperature rise of the food container can be adjusted more uniformly. However, this is not the case depending on how the direct fire hits.

  The food container and the liquid container are formed of a material that can be heated directly below, and the material that can be heated directly below is not particularly limited, but an aluminum sheet is preferable because of its good thermal conductivity and low cost. Moreover, it is preferable to apply | coat the food containing 10% or more of oil or oil to the bottom face of a food accommodating part, and it can heat uniformly and rapidly by apply | coating the food containing 10% or more of oil or oil.

  Moreover, steaming and baking of food can be performed simultaneously by providing a lid that covers the food storage and the liquid storage.

  The food to be heated in the food container for direct heating according to the present invention can be applied to foods to be steamed, such as fried eggs, steamed chicken, steamed fish, baked goods, etc. Fees can also be used. Moreover, while storing frozen food in a food storage part beforehand, it can be used also as a food packaging body by storing ice, frozen soup, etc. in a liquid storage part.
