Abstract

PURPOSE:To provide a steaming function to an electronic oven by a method wherein an atomizing pipe formed with a nozzle part at its extreme end and a capillary tube are provided so as to constitute a closed container having water therein. CONSTITUTION:Upon applying a heating operation within an electronic oven, water W for steam within a closed container 1 is boiled, its inner pressure is increased, resulting in that hot water within the container is pushed up through a capillary tube 4. In turn, the steam generated within the container 1 is strongly injected through a nozzle 3 from an atomizing pipe 2. Then, the hot water pushed up from the capillary tube 4 with this steam is dispersed in a spray form to make stomized water. The humidified state is attained through this atomized water to prevent a food from being dried. A steam gener ating device is small in size the food is set in a food packaging container, the packaged container is heated within an electronic oven to humidified or the container is separately placed within the electronic oven away from the food and then the container is heated with a micro-wave to humidify within the oven and thus a humidifying of the food can be carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) 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 either in a commercially available package or after wrapping the food.

Sprinkling water is also used in some households to prevent dryness.

(Problem to be solved by the invention) However, in the conventional system described above, the former method dries the food due to microwave heating, and it is difficult to avoid a significant deterioration in taste compared to heating with a steamer etc. do not have. Furthermore, even the latter method cannot prevent complete drying, and although this method may be used on a small scale at home, it is not suitable at all for large scale industrial use.

In this way, conventional systems cannot combine the convenience of microwave heating with the ability to prevent deterioration of flavor, especially the ability to prevent dryness. There are no known examples of this being successful.

(Means for Solving the Problems) As described above, the present invention combines the convenience of microwave heating with the ability to prevent drying and improve taste, making microwave ovens more effective. In particular, it was developed for the purpose of developing a new system that industrially prevents drying caused by heating in a microwave oven with a simple and low cost of 1.

As a result of considering various aspects in order to achieve the above objective, we developed a steam generator with a specific structure as detailed below, and found new knowledge that the intended objective could be achieved by using this device. Obtained.

That is, the steam generator according to the present invention is mainly composed of a closed container equipped with a spray tube having a nozzle at its tip and a capillary tube, but the details will be explained below with reference to the drawings. Describe.

Although the steam generation equipment according to the present invention is removed from the closed container 1,
There is no particular limitation on the shape, and any shape such as a box, cylinder, sphere, cone, or pyramid can be used. The airtight container 1 may be formed integrally as shown in FIG. 1, or it may be divided into two or more parts as shown in FIG. 2 and later integrated by screwing or other methods. You can do it like this.

A spray tube 2 and a capillary tube 4 are housed and installed in this airtight container. A nozzle portion 3 is formed at the tip of the spray tube 2, and it is placed close to and above the capillary tube 4. put. A capillary tube 4 having an inner diameter large enough to suck up the steam water W in the closed vessel 1 is appropriately used. The lower end of the capillary tube 4 is preferably long enough to reach the bottom of the closed container L so that all the steam water W can be used without leaving it behind, and it should be extended further to the extent that it meanders at the bottom. You can.

On the other hand, the lower end of the spray pipe 2 is positioned above the level A of the steam water W. If necessary, these pipes may be attached to the lid of the container and their lengths may be freely adjustable.

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

That is, the hermetic container 1 is divided into a lid part 1a and a main body part 1b, and the two are hermetically coupled by a screw or other connection part 1c that maintains airtightness to form the hermetic container 1. In this 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 goes without saying that the configuration must be such that airtightness is maintained.

The action of this steam generation position '3A is as follows. That is, when this is heated in a microwave oven, the steam water W inside the closed container boils, thereby increasing the internal pressure, and as a result, the hot water inside the container is pushed upward through the capillary tube 4.

On the other hand, steam generated in the container 1 is vigorously jetted out from the spray pipe 2 through the nozzle 3. Then, due to this steam, the hot water pushed up from the capillary tube 4 is scattered in the form of a spray and diffused in the form of mist, humidifying the food and preventing it from drying out.

The steam generator according to the present invention can be made small and packaged together with food in a food packaging container, and can be heated in a microwave oven to humidify the food, or placed separately in a microwave oven. Microwave heating can also humidify the inside of the refrigerator and dry food. Further, a steam generating device may be installed in advance in the microwave oven in a detachable manner at the design stage.

Furthermore, if necessary, if the steam water W is repacked and sold separately, the steam generator can be used any number of times. On the other hand, it is also possible to manufacture extremely low-cost steam generators using inexpensive materials and through body molding and other rationalization, and then create disposable type equipment that can be disposed of after use. can.

The steam water used in this steam generator absorbs microwaves well and increases the temperature by adding electrolytes such as salt or potassium chloride to an extent that does not affect the food, or by using mineral water etc. hasten the
It can also generate steam quickly.

As mentioned above, the steam generator according to the present invention has no restrictions on its size or shape, and any material that can be used in a microwave oven can be used, such as the following: Examples include: pottery,
Ceramics such as porcelain and glass; polypropylene, polystyrene and other synthetic resins; paper, processed paper; composite materials laminated with these materials, etc.

As an example, a commercially available microwave oven steam generator was housed in a microwave oven along with a disposable type steam generator shown in FIG. 1 made of polypropylene and containing ordinary water.

When the switch was turned on, a powerful spray of steam was generated inside the refrigerator, and the shumai was steamed. After the heat treatment, a beautiful gloss was observed on the surface of the shumai, and when eaten, the texture and flavor were comparable to those steamed in a steamer.

Example 2 Gyoza was heated in a microwave oven using a two-part steam generator equipped with a lid as shown in FIG. 2 and containing mineral water inside.

As a result, the obtained dumplings were fresh and shiny, and when eaten, they had the flavor and texture of freshly made dumplings.

(Effects of the Invention) For the first time, the present invention has solved the problem of dryness in heating in a microwave oven, and has made it possible to provide the microwave oven with the function of, for example, a steamer. Therefore, for the first time, the present invention has succeeded in simultaneously satisfying the convenience of microwave heating and the delicious taste without drying, and has succeeded in further expanding the range of applications of microwave cooking.

Moreover, the steam generator according to the present invention not only succeeds in extremely simplifying the structure, but also does not require any special power source to drive it; simply installing it inside the microwave oven is sufficient. Therefore, rather than being an energy-saving type, it can be said to be something that does not require energy, and is extremely excellent. Furthermore, there is no need to worry about safety at all, making it suitable for use by housewives at home.
