Description

Description: TECHNICAL FIELD The present invention relates to a steam generator particularly suitable for use in a microwave oven, and a humidifying method for a microwave oven using the same.

(Prior Art) Conventionally, when heating food using a microwave oven, microwave heating is performed as it is in a commercially available package or after wrapping the food.

In addition, a method of sprinkling water is also used at home for the purpose of preventing dryness.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional system, the former method causes the food to be dried by microwave heating, and avoids a significant deterioration in taste as compared with the case of heating with a steamer or the like. Absent.

Also, the latter method cannot prevent complete drying, and this method is completely unsuitable for large-scale industrial use, whether it is performed on a small scale at home.

As described above, in the conventional system, it is not possible to combine the convenience of microwave heating with the prevention of deterioration of taste, especially the prevention of drying, and conventionally, in the microwave oven, the industrial system for preventing drying is perfect. There are no known successful cases.

(Means for Solving the Problems) As described above, the present invention makes the microwave oven more effective by satisfying both the simple point of heating by the microwave oven and the point of improving the taste by preventing drying. It is intended for use, and in particular, for the purpose of developing a new system for industrially preventing drying by heating in a microwave oven at a simple and low cost.

As a result of studies from various fields to achieve the above purpose, we developed a steam generator with a specific structure as described in detail below, and obtained new knowledge that the intended purpose can be achieved by using this device. It was

That is, the steam generator according to the present invention is mainly
It is composed of a closed container having a spray tube having a nozzle formed at its tip and a capillary tube, which will be described in detail below with reference to the drawings.

The steam generator according to the present invention comprises the closed container 1, but the shape thereof is not particularly limited, and any shape such as a box shape, a cylindrical shape, a spherical shape, a conical shape, a pyramid shape can be used. is there. The closed container 1 may be integrally formed as shown in FIG. 1, or may be divided into two or more parts as shown in FIG. 2 and integrated later by screwing or another method. You may do it.

Inside this closed container 1, a spray tube 2 and a capillary tube 4 are provided.
The nozzle portion 3 is formed in the tip portion of the spray tube 2 and is exposed in the vicinity of and above the capillary tube 4. As the capillary tube 4, one having an inner diameter enough to suck up the steam water W in the closed container 1 is appropriately used. The lower end of the capillary tube 4 is preferably of a length that reaches the bottom of the closed container 1 so that the steam water W can be used entirely without leaving it, and it is further extended so as to meander at the bottom. May be. On the other hand, the lower end of the spray pipe 2 is positioned above the level A of the steam water W. If needed, these pipes
It may be attached to the lid of the container and its length may be freely adjusted.

FIG. 2 illustrates another embodiment of the steam generator according to the present invention, showing a device of a type in which a lid portion and a main body portion are divided.

That is, the closed container 1 is divided into a lid portion 1a and a main body portion 1b, and the both are screwed together or other connecting portion 1c for maintaining airtightness.
The airtight connection is made by the above to form the closed container 1. In the present embodiment, the capillary tube 4 and the spray tube 2 are fixedly attached to the lid portion 1a, but it is of course possible to attach them detachably. However, in the latter case, it is natural that the structure must be kept airtight.

 The operation of this steam generator is as follows.

That is, when it is heated in the microwave oven, the steam water W in the closed container 1 boils, which increases the internal pressure, and as a result, the hot water in the container is pushed upward through the capillary tube 4.

On the other hand, the steam generated in the container 1 is vigorously ejected from the spray pipe 2 through the nozzle 3. Then, the steam causes the hot water pushed up from the capillary tube 4 to be scattered in a spray form and diffused in a mist form to humidify and prevent the food from being dried.

The steam generator according to the present invention is miniaturized and packaged together with food in a food packaging container, and the packaging container is heated in a microwave to humidify the food, or placed separately from the food in a microwave oven. It is also possible to humidify the inside of the refrigerator by heating with microwaves to dry the food. Further, the steam generator may be detachably incorporated in the microwave oven in advance at the design stage.

Also, if necessary, the steam generator W can be used repeatedly as many times as needed if the steam water W is separately packaged and sold as a refill. And conversely, using an inexpensive material, integrated molding and other rationalization have been made to manufacture a very low cost steam generator,
It may be a disposable type device that can be discarded after use.

Water for steam used in this steam generator absorbs microwaves well and increases temperature by adding electrolytes such as salt and potassium chloride to the extent that foods are not affected, or by using mineral water. The steam can be generated earlier.

The steam generator according to the present invention has no limitation on the size or shape thereof as described above, and as for the material thereof, any material can be used as long as it can be used in the microwave oven, for example, the following. Examples thereof include ceramics such as pottery, porcelain and glass; polypropylene, polystyrene and other synthetic resins; paper, processed paper; composite materials obtained by laminating these.

Example 1 A commercially available microwave oven for shimmy was housed in a microwave oven together with a steam generator shown in FIG. 1 of a disposable type which was made of polypropylene and contained ordinary water.

When the switch was turned on, a violent steam spray was generated in the chamber, and the steaming heat treatment of shimai was performed. The shimumai after heat treatment had a beautiful gloss on the surface, and when it was eaten, the texture and flavor were confirmed to be comparable to those steamed in a steamer.

Example 2 A two-part steam generator provided with a lid as shown in FIG. 2 was used, and mineral water was housed in the steam generator, and the heat treatment of gyosa was performed in a microwave oven.

As a result, the obtained gyoza is shiny and shiny,
When this was eaten, a fresh flavored texture was obtained.

(Effects of the Invention) The present invention solves the problem of drying in microwave heating for the first time, and the function of a steamer can be added to the microwave.

Therefore, for the first time, the present invention succeeded in satisfying the convenience of microwave heating and the deliciousness without drying at the same time, and succeeded in further expanding the range of application of microwave cooking.

Moreover, the steam generator according to the present invention has not only succeeded in the ultimate simplification of the structure, but also does not require any special power source to drive it, and it is sufficient if it is installed in the microwave oven. Therefore, rather than being an energy-saving type, it can be said that it does not require energy, which is very excellent. Further, there is no worry in terms of safety, and it is suitable for a housewife to use at home.
