Description

  The present invention relates to an improvement of a container (susceptor mount) using a sheet for cooking food by heating or scorching food with microwaves in a microwave oven.

  By using a heating element (susceptor) that generates heat from microwaves generated from a microwave oven, the food is baked to produce baked eyes and a crispy texture that are difficult with microwave heating. The technology is known and has been used for pizza, fried potatoes, deep-fried chicken, grilled fish and fillets to date (Japanese Utility Model Laid-Open No. 1-82829, Japanese Patent Application Laid-Open No. 2006-75617, Japanese Patent Application Laid-Open No. 2008-62990). Issue gazette).

However, the above configuration has the following problems.
(1) Ingredients after heating, especially fish fillets, tend to adhere to the heating element on the bottom side of the mount, and when the fish is lifted from the heating element on the bottom side, the body tends to collapse. This is especially noticeable when the fish is Saikyo pickled or pickled.
(2) Since the drip from the food material such as the fillet remains on the heating element and solidifies by heating, the adhesion between the food material and the heating element is promoted and the flavor is deteriorated.
(3) The heating element on the bottom side mount is in contact with the bottom surface of the microwave oven, and in the case of a turntable type microwave oven, microwaves are irradiated from above, so that sufficient microwaves are applied to the heating element on the bottom side. Does not hit and does not generate heat easily.
(4) Depending on the fillet, the thickness in the height direction and the width in the horizontal direction when placed on the tray are different, and depending on the part, the paste of fat is also different. For this reason, unevenness occurs in the baking due to the difference in volume of the fillet portion to be heated and the difference in the content of fat.
(5) As a lock mechanism that restrains the container assembly shape by the mount, a U-shaped notch is formed at the center of the outer edge of one mount, and a pair of cut lines are inserted at locations corresponding to the notches at the outer edge of the other mount Since the hook piece is formed in the notch and is hooked at one central position, in the case of fish that warps particularly strongly by heating, the end of the heating body is lifted by the warp, and the heating effect is increased. drop down. Moreover, the appearance of the fish after heating is also deteriorated.
(6) The microwave irradiation direction and the point of concentration differ depending on the type of microwave oven, and strength is generated at the portion of the heating element, so a difference occurs in the grille depending on the difference in the microwave oven and the place where the container is placed.
Therefore, the present applicant applies microwaves to the heating element on the bottom side of the container containing the foodstuff, discharges the drip dripping from the foodstuff to the outside of the container, and removes unnecessary steam in the container. Japanese Patent Application No. 2010-273071 was proposed in order to provide a microwave heating container that can be discharged.
Further, as a result of earnest research, the present applicant has come up with an invention of a microwave oven heating container that can optimally heat the temperature inside the container.
