[0002]

At present, various types of packaged foods are sold at convenience stores and are widely used by consumers. Generally, bento boxes sold at convenience stores are manufactured in a batch at a factory and then delivered to each shop to reach a consumer. The packaged food delivered to each store is stored at a relatively low temperature until it reaches the consumers' hands, and at each store, the packaged food is heated in a microwave oven at the request of each consumer. We carry out service to do.

By the way, there are two types of foods, one that feels better when heated and the other that feels better when cooled. For example, in the case of pilaf and vegetable salad, the pilaf feels better when eaten in a warm state, and the vegetable salad feels better when eaten in a cold state. In some cases, you may want to sell it as a food packaged in a container. When selling such a packaged food, the heating service by the microwave oven as described above may be requested by the consumer. In such a case, if the container-packaged food is heated together with the container, the whole product becomes hot and the vegetable salad cannot be eaten deliciously. Therefore, the types of foods that can be stored at the same time may be limited.

In the summer, foods such as buckwheat that can be eaten with a good taste when chilled are popular. Therefore, packaged foods containing buckwheat and tsuyu in one container are also sold at convenience stores. There is. It is convenient for inventory management of merchandise if such a packaged food is stored in a frozen state at each store so that it can be sold.

When the frozen buckwheat and tsuyu are stored in a container and thawed at each store, the buckwheat is completely thawed and the product temperature rises to a certain temperature. If it can be thawed as described above, it is possible to supply consumers with a packaged food that can be eaten immediately after taking it home.

However, even in such a case, if the entire container is heated evenly in the microwave oven, the temperature rises to the boil if the heating is too strong, while if the heating is too weak, the buckwheat is heated. Will be frozen. Therefore, it is difficult to thaw buckwheat and tsuyu so that each has an appropriate temperature.

The present invention has been made in view of the above circumstances, and container-packaged foods in which two or more different types of foods are contained in one container are respectively selected according to the properties of the contained foods. It is an object of the present invention to provide a method for heating or thawing the food under appropriate conditions and supplying the stored food to consumers at the optimum product temperature.

Then, the selecting means 33 can selectively heat any of the regions 32a to 32f of the upper tray 31 of the microwave oven 30 on which the object to be heated is placed, as shown in FIG. 2B. The selection means 33 may be a mere changeover switch having a function of selecting an electromagnetic wave generation source to be activated, and the electromagnetic wave generation source to be activated is automatically detected by reading a bar code or the like attached to a product. It may be one that can be selected. By this selection means 33,
The microwave oven 30 can be adapted to other types of bento.

As shown in FIG. 2A, the areas 32a to 32f have a positional relationship as shown in FIG. 2B when the front end of the tray 31 is 31a and the rear end is 31b. It is located in. It should be noted that the electromagnetic wave generation source is each area 32
They are provided at substantially the center of a to 32f, that is, above the positions of the white circles 34a to 34f shown in FIG. By selecting one of the electromagnetic wave generating sources arranged in this way by the selecting means 33, the region located below the selected electromagnetic wave generating source becomes a region where the electromagnetic wave energy is high when the microwave oven 30 is operated. , The other regions are regions where the electromagnetic wave energy is low. In this way, the microwave oven 30 can freely adjust the electromagnetic wave energy distribution inside.

The microwave oven 30 is preferably the same one at each of the convenience stores. As a result, a unified manual can be prepared in each store, and the present invention can be easily implemented in each store. Further, in the present embodiment, the number of electromagnetic wave generation sources of the microwave oven 30 is set to 6, but the number is not limited to this.

Next, a method of cooking the zaru soba bento 5 will be described.

First, as shown in FIGS. 3 (a) and 3 (b), the buckwheat 1 is placed in the buckwheat accommodating area 11 of the container 10 in an amount of about 210 g. FIG. 3B shows B in FIG.
-B shows a cross section. As shown in FIG. 3 (b), when the buckwheat 1 is arranged, the buckwheat storage area 11 has a larger number of buckwheat 1 in the areas 11 a, 11 b, 11 e, and 11 f on both sides in the longitudinal direction. The buckwheat 1 in the regions 11c and 11d, which are the central portions in the direction, is arranged so as to be small. Regions 11a, 11 on both sides in the longitudinal direction
To add more buckwheat 1 b, 11e, 11f,
As will be described later, the container 10 is placed in the tray 31 of the microwave oven 30.
11a, 11b, 11e, 11 when placed on the
This is because it is selected so that the electromagnetic wave of the microwave oven 30 acts on f. Therefore, this arrangement method is determined by the relationship with the arrangement position of the electromagnetic wave generation source of the microwave oven 30.

The buckwheat 1 is thoroughly drained before being stored in the buckwheat storage area 11 so that it can be stably thawed in the later-described thawing step, and after the buckwheat is prevented from adhering to the buckwheat as much as possible, the buckwheat It is stored in the storage area 11.

Next, the sealed bag body 2 accommodating the confectionery 21 via the frame 12a is accommodated in the confectionery accommodation area 12 of the container 10, and the condiment 3 is accommodated in the condiment accommodation area 13. After that, the lid 14 is attached to the buckwheat storage area 11 and the seasoning storage area 13, and the lid 15 is attached to the tsuyu storage area 12, thereby completing the storage step.

Next, the container in which the buckwheat 1, the hermetically sealed bag 2 and the seasoning 3 are stored is cooled to -15 ° C, whereby the buckwheat 1 stored in the container 10 and the soup 21 are provided. Condiment 3 is frozen. The freezing process is performed in the factory, and the zaru soba bento is then delivered to each store by a refrigeration car and stored in the freezer provided in each store.

Although the buckwheat 1, the sealed bag body 2 and the seasoning 3 are stored in the container 10 and then frozen, the buckwheat 1, the sealed bag body 2 and the seasoning 3 are conversely described.
May be stored in the container 10 after being frozen. An example of this is shown below.

That is, first, the buckwheat 1 is sufficiently drained, and then a predetermined amount is put on a freezing tray 22 divided into six regions 22a to 22f by a partition plate as shown in FIG. Also in this case, the buckwheat 1 is the freezing tray 2
2 regions 22a, 22b, 22e, 22 on both sides in the longitudinal direction
The buckwheat f of f is increased, and the buckwheat 1 of the regions 22c and 22d at the central portion in the longitudinal direction of the freezing tray 22 is arranged to be small.

Next, the buckwheat 1 thus arranged on the freezing tray 22 is frozen together with the freezing tray 22.

When the freezing of the buckwheat 1 is completed, the freezing tray 22 on which the buckwheat 1 is placed is carried to above the buckwheat storage area 11 of the container 10, and then the bottom 22g of the freezing tray 22 of the freezing tray 22 is on top. Turned inside out.
As a result, the buckwheat 1 placed on the freezing tray 22 falls toward the buckwheat storage area 11 below and is stored in the buckwheat storage area 11. In this case, the area 2 of the freezing tray 22
The buckwheat 1 that has been placed on the 2a is stored in the area 11a of the buckwheat storage area 11, and similarly, in the area 2 of the freezing tray 22.
The buckwheat 1 arranged on 2b to 22f is stored in the areas 11b to 11f of the buckwheat storage area 11, respectively.
In this case, the buckwheat 1 is stored in the buckwheat storage area 11 as shown in FIG.

Next, after the hermetically sealed bag 2 and the condiment 3 containing the soup 21 are frozen, the soup storage area 12 of the container 10 is frozen.
And the condiment storage area 13, respectively.

After that, the lid 14 is mounted on the buckwheat storage area 11 and the seasoning storage area 13 and the lid 15 is mounted on the tsuyu storage area 12 to prepare the packaged food 5.

As described above, even when the packed food 5 is prepared by preliminarily freezing the stored foods and then storing the foods in the predetermined position of the container 10, the above-mentioned freezing and storing steps are performed in the factory. Thereafter, the packaged food 5 is delivered to each store by a freezing vehicle and stored in a freezer provided in each store.

At each store, customers make zaru soba lunch 5
When there is an offer to purchase, the zaru soba bento 5 is taken out of the freezer.

Next, the selection means 33 of the microwave oven 30 selects the electromagnetic wave generation source corresponding to the regions 32c and 32d to be heated intensively among the regions 32a to 32f of the tray 31.

Next, as shown in FIG.
2 and the condiment storage area 13 facing toward the back, the edge 10a on the side of the confectionery storage area 12 and the condiment storage area 13 is placed on the tray 3
1 zaru soba bento so that it coincides with the rear end 31b
Is placed on the tray 31 at a substantially central portion in the left-right direction. Thereby, the buckwheat storage area 1 in which the buckwheat 1 which is the first food is stored
1 is a region 32c of the tray 31 where the electromagnetic wave energy is high,
At the position corresponding to 32d, the syrup storage area 12 storing the syrup 21 that is the second food corresponds to a position corresponding to the low electromagnetic wave energy area 32b of the tray 31, and the condiment storage area 13 corresponds to the area 32a of the tray 31. Are arranged at the positions where

Since the temperature of the spice 3 after thawing does not matter, it may be placed at a site other than directly below the electromagnetic wave generation source. Condiment 3 is buckwheat 1 and tuna 21
This is because the amount is extremely smaller than that of the above, and when the mixture is added to the sou 21, the temperature of the sou 21 is immediately equalized.

Thus, either edge 10 of the container 10
a-10d to either end 31a-31 of the tray 31
Saru soba lunch 5
Can be easily positioned when it is placed on the tray 31 of the microwave oven 30. That is, the container 10
The shape and size and the method of arranging the food items 1, 2, and 3 to be stored in the container are determined in consideration of the installation position of the electromagnetic wave generation source of the microwave oven 30 in advance. Therefore, for other types of bento as well, it is possible to implement the present invention by determining the shape and size of the container and the method of arranging the food to be stored in the container in consideration of the installation position of the electromagnetic wave generation source. It is possible.

Next, the zaru soba lunch 5 is placed in the microwave oven 30.
The buckwheat 1, the sauce 21 and the condiment 3 stored in the container 10 are thawed. The heating of the zaru soba lunch 5 is performed by changing the electromagnetic wave output in three stages. For example, power 1 in the first heating stage
After heating at 450w for 36 seconds, it is heated at a power of 530w for 26 seconds in the second heating step, and is further heated at a power of 150w for 120 seconds in the third heating step. Especially in the third heating stage, buckwheat 1 and soup 21
In order to prevent the rapid temperature rise of No. 2 and to reduce the variation in the finish temperature of the buckwheat 1 and the soybean 21 after thawing, it is heated with a minute output for a long time.

After the thawing is completed, the zaru soba lunch 5 is supplied to the customer.

Table 1 shows an example of the temperature distribution of the buckwheat 1 in the buckwheat storage area 11 immediately after thawing. Here, buckwheat storage area 1
The temperature of the regions 11a, 11b, 11e, 11f at both ends of 1 tends to be slightly higher, but this is because the regions 11a, 11b, 11e, 11f at both ends are located directly under the electromagnetic wave generation source, respectively. Is. The temperature of the soup 21 immediately after thawing is between approximately 0 ° C and 5 ° C.

[0040]

[Table 1] In this way, the temperature distribution is slightly non-uniform immediately after thawing. Therefore, it is necessary to leave it for about 3 minutes until the temperature distribution becomes uniform. However, since this Saru soba bento 5 is supplied at a convenience store. An appropriate time period elapses while the customer takes it home, and the temperature distribution is just good by the time the customer eats the zaru soba lunch 5.

As described above, according to the present embodiment, the buckwheat 1
Since the soup 21 and the soup 21 can be used at a temperature suitable for each, it is possible to provide a delicious colander soba lunch 5. In addition, according to the present embodiment, since the zaru soba bento 5 can be stored in each store in a frozen state, it is possible to reduce the discard of the inventory due to the expiration of the expiration date.

As described above, in the above embodiment, the method of thawing the once-boiled buckwheat 1 and the soy sauce 21 to the temperature suitable for each is shown, but the present invention is not limited to this. That is, two or more types of food are stored in a container, and the packaged food stored at room temperature or in a refrigerator or freezer is heated to a temperature suitable for each customer according to the type of the stored food, and then the customer It can be applied to the supply method.

For example, when heating a packaged food containing pilaf and vegetable salad in one container and supplying it to the customer, only the pilaf storage area of the container is intensively heated to store the vegetable salad. By not heating the area, it is possible according to the present invention to provide the customer with the pilaf and the vegetable salad at the respective suitable product temperatures.

[0044]

According to the invention of claim 1, the first food is heated with high electromagnetic energy by the microwave oven capable of freely adjusting the electromagnetic wave energy distribution inside,
Since the food is heated with low electromagnetic energy, the temperature of the first food can be finished higher than the temperature of the second food after being heated by the microwave oven. Therefore, when a packaged food containing two or more different types of food is heated and provided to a customer, the food can be provided at a temperature at which a person feels delicious when eating each food.

According to the second aspect of the present invention, the first food and the second food that have been once frozen are heated with high electromagnetic energy by the microwave oven capable of freely adjusting the electromagnetic wave energy distribution inside. Since the second food is heated with low electromagnetic energy, the temperature of the first food can be thawed to a state higher than the temperature of the second food after being heated by the microwave oven. For this reason,
When a container-packaged food containing two or more different kinds of food is heated and provided to a customer, the food can be provided at a temperature at which a person feels delicious when eating each food. Further, since the bento can be stored in each store in a frozen state, it is possible to reduce the disposal of the inventory due to expiration of the expiration date.
