2. Description of the Related Art Conventionally, foods are roughly classified into two types, foods of soups and other foods. For example, noodles are also classified into soup noodles such as ramen, udon and soba and noodles other than soup such as yakisoba and fried udon. However, these two types of noodles cannot be cooked at the same time because the cooking method and the heating amount required for cooking are different. For the same reason, it was also difficult to thaw and heat the menu of frozen soup noodles and frozen cooked rice in a microwave oven at the same time to bring them into proper cooking states.

On the other hand, in recent years, people's tastes have diversified, and the tendency has become noticeable in meal menus. For example, in Japanese restaurants, set menus are popular, and set menus that combine udon or soba with chirashi sushi, tori-meshi, curry rice, tempura bowl, tonkatsu, etc. are becoming popular. However, because frozen noodles and frozen cooked rice have different thaw heating times, they cannot be thawed at the same time and must be thawed separately. There was a problem.

In addition, when one person wants to eat two types of soup noodles and cooked rice in one meal, the ingredients have to be purchased separately and cooked, which is time and economically feasible. It is disadvantageous, and it would be economical and convenient if one could prepare one of these two types of ingredients in advance and cook it in one operation.

However, it is preferable to appropriately select, for example, several fine holes of about 0.1 to 2 mm are provided.

Examples of the noodles used in the present invention include Chinese noodles such as ramen, buckwheat noodles such as kake soba, and udon noodles. The method for freezing these noodles is not particularly limited, but it is preferable to spray a lecithin solution or a gelatin solution and freeze it when the boiled noodles are subjected to the rough heat to be frozen. According to such a method, the sticking of the noodles after the rough heat is prevented is prevented, and the frozen portion in the frozen noodles can be reduced, so that the heating time at the time of thawing can be shortened and the noodles with elasticity can be obtained. be able to.

[0011] For example, in the case of Chinese noodles, it is obtained by blowing air to a boiled Chinese noodles with a fan or the like to remove rough heat, and then spraying a lecithin solution of 1 to 4% by weight for rapid freezing. . In the case of buckwheat noodles and udon noodles, boiled noodles are soaked in cold water once to cool, and then the water content on the noodle surface is evaporated,
It is obtained by spraying 1 to 4% by weight lecithin solution and 2 to 4% by weight gelatin solution for quick freezing.

[0012] Examples of the cooked rice used in the present invention include white rice, fried rice, gomekowa, chirashizushi, curry rice, tempura bowl, pork cutlet and the like, which are preliminarily cooked and then rapidly frozen by a known method. . The frozen food-containing thaw container of the present invention, for example, after storing cooked noodles and frozen cooked rice in the container body and the lid, respectively,
It is preferable to perform rapid freezing in nitrogen gas at, for example, −60 ° C. and integrally package. By rapidly freezing in nitrogen gas, it is possible to suppress the growth of bacteria and so on. Therefore, even when the frozen food defrosting container is stored in a chilled state (0 to 5 ° C), the increase of bacteria in noodles and cooked rice can be prevented. It can be suppressed for a long time (one month or more). Therefore, during shipping from the manufacturer to the customer, such items should be stored frozen,
