DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to desserts which are thawed and used by an electromagnetic cooker, so-called microwave oven, and frozen foods such as staple foods and prepared dishes which are heated and cooked simultaneously with thawing.

[0002]

2. Description of the Related Art In general, frozen ingredients are also called frozen foods. In addition to staple food such as rice and noodles, food ingredients such as vegetables and fish meat are prepared raw or pre-cooked and seasoned. It is frozen and solidified, and packed into bags, boxes, paper cups, etc., as necessary, to produce products. At the time of use, they are taken out of a bag or a box, or put in a paper cup, put in an electronic cooker, thawed, heated and heated, and then served to a dining table.

[0003]

However, the electromagnetic cooker used in ordinary households has a small output of about 600 watts / hour, and it takes a long time to thaw and cook this kind of food. When preparing a large family meal,
This had to be cooked in several batches, and there was a problem that the one cooked earlier cooled when the one cooked later became warm. Such a problem also occurs when a large amount of commercial materials are cooked and served to customers.
In order to solve such a problem, the output of the electromagnetic cooker may be increased. However, in addition to the increase in power consumption, a large cooker requires a large installation space and causes a problem that the inside of the kitchen is further narrowed.

[0004]

SUMMARY OF THE INVENTION The above-mentioned object is attained by forming a nodule formed by a food material constituting a food material and passing through a central portion thereof and opening to an outer surface. In addition, the food material is frozen and solidified, and the food material is formed into a nodular shape and has a through hole that opens to the outside through the central portion, or is solidified, or the food material is formed along the inner surface of a substantially cylindrical food container. It is held in a nodular form, in which there is formed a through hole that passes through the center and opens to the outside. Further, in the lid for closing the opening on the upper surface of the cylindrical food container, an empty room formed by upper and lower lid plates is formed, and the empty room is passed through a communication hole formed in the lower lid plate. It is configured to communicate with a cylindrical food container and to support a water absorbing material inside the empty room.

[0005]

The food material is frozen into a predetermined size by a means of freezing or a means of being contained in a container, and is frozen to produce a frozen food material. The lines of magnetic force generated by the electromagnetic cooker act on the food material from both the circular outer surface of the food material and the inner surface of the through hole, and excite the moisture contained therein to generate heat. In other words, by forming the through holes, the apparent thickness of the food material forming the baby lump is reduced, the magnetic permeability is increased, and the water is more strongly vibrated. In addition, if the food material is made cylindrical, the outer surface will not be uneven and thin,
The thickness between the outer surface and the through hole becomes uniform, and the action of the magnetic force lines is performed uniformly over the whole. In addition, the electromagnetic force acts directly on the food material to generate heat, defrosting and heating, while heating the water contained in the water-absorbing material into steam, and the steam spouts into the container through the communication hole, where it is discharged. Certain food ingredients are heated indirectly via steam.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. In FIG. 1, reference numeral 10 denotes a frozen food for electromagnetic cooking according to the present invention. In this embodiment, as shown in FIG. 2, the frozen food 10 comprises a paper cup 20, which is a container for the frozen food 10, and a food 30 accommodated therein. Reference numeral 40 denotes a paper lid that closes an upper opening of the paper cup 20. Reference numeral 11 denotes a tray made of a non-magnetic material on which the paper cup 20 is placed, which is installed in an electromagnetic cooker 12, a so-called microwave oven. 13 is the electromagnetic cooker 12
It is a magnetron that is the main part of.

[0007] The paper cup 20 has a paper-made side wall 21 whose lower side is made thin and a paper bottom plate 2 which closes the narrow lower opening.
The food material 30 is put in the inside, and is frozen at about −20 ° C. In this embodiment, the food material 30 is instant noodles prepared by mixing and boiled ingredients.
Is formed. In this embodiment, the through-hole 31 is provided penetrating vertically, but this configuration is not essential and may have a bottom, but it is desirable that the thickness of the bottom is not larger than the hole diameter.

The lid 40 has an opening at the top and bottom of the cylindrical side wall 41 closed by an upper lid plate 42 and a lower lid plate 43 to form an empty space 44 therein. Thin paper is folded and stored as the water absorbing material 45. Reference numeral 46 denotes a communication hole which is formed at the center of the lower cover plate 43 and communicates between the front and back.

Next, the method of heating and cooking the frozen food 10 for electromagnetic cooking described in the above embodiment will be described. First, a predetermined amount of water is added to the water absorbing material 45, and the vacant space 44 formed in the lid 40 is formed.
Then, it is put on a paper cup 20, placed on a tray 11 installed in a microwave oven 12, and after closing a lid, the magnetron 13 is energized. When the magnetron 13 operates, the water contained in the food material 30 and the water absorbed by the water absorbing material 45 are excited. Therefore, the food material 30 is thawed and heated. At this time, the water absorbed by the water-absorbing material 45 is also heated to a high temperature and becomes steam, filling the empty space 44.
Through the paper cup 20.

[0010] When the food material 30 is excited by the magnetron 13, the food material 30 in the form of a rod has the through-holes 31 in the axial center portion. Electromagnetic action from both sides, and the action of moisture contained therein rapidly generates heat. The high-temperature water vapor blown into the paper cup 20 from the communication hole 46 also acts on the food material 30 from both the outer surface of the food material 30 and the inner surface of the through-hole 31, so that the temperature rises rapidly. In addition,
The presence of water vapor acts to prevent the surface from drying when the temperature rises.

In the above embodiment, the food material 30 is formed in a cylindrical shape, but this is not an essential requirement. The food material 30 may be an elliptical tube or a square tube. The efficiency is lower than the shape, and the time required for heating is slightly longer.

Further, in the above-described embodiment, an example is shown in which the cylindrical food material 30 is supported with its axis oriented vertically, but the supporting posture is not limited to this, and as shown in FIG. Even if the food material 30 is taken out of the paper cup 20 and the axis is supported in the horizontal direction, the effect of the heating is not changed, and the food material 30 and the tray 11 are in line contact, and the heat radiation area is reduced. In FIG. 3, reference numeral 32 denotes a hanger for the food material 30 being heated together with the food material 30.

Further, as shown in FIG.
4 does not change the function and effect of heating by the magnetron 13, and the bowl-shaped container 14 and the food material 30 are supported at two points, an upper part and a lower part. Thus, the heat radiation area is further reduced.

[0014]

According to the first aspect of the present invention, by forming a through hole in a food material, the wall thickness is reduced, and the electromagnetic force acting on the food material is efficiently transmitted from the front and back, so that thawing and cooking can be performed. Done quickly. In addition, there is no need to increase the size of the electromagnetic cooker itself, which reduces the installation space and is economically advantageous. According to the second aspect of the present invention, the foodstuff for freezing is formed into a lump without using a container, so that it is not necessary to remove the container when thawing or heating by the electromagnetic cooker, and the cooking time can be reduced. According to the invention of claim 3, the food material is heated while being supported by the relatively wide bottom surface in the vertical direction. However, the wide bottom surface is supported by the container having a small specific heat, so that heat loss is small and rapid. Is cooked. According to the invention of claim 4, the food material is heated by the action of both the electromagnetic force and the water vapor, and the food material is efficiently heated because a sufficient amount of water is supplied to the food material.
Cooked more rapidly. And so on.
