DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of heating food and a pot, and more particularly, to the heating of foodstuffs that need to be heated for a long time at a high temperature when onions or sauces are present. The purpose is to pursue techniques related to methods and pots.

[0002]

2. Description of the Related Art Conventionally, when heating food, steam, gas, or electricity has been used, but in each case, only one type of heat source has been used. Of course,
The pot was also made of iron, stainless steel, a multilayer of iron and stainless steel, or one of copper. Also, there was no idea of cooling food after heating it.

[0003]

However, such conventional food heating methods and pots have the following problems.

First, when one type of heat source is used, the heating temperature may be too high, the heating temperature may be low, or the heating temperature may be immediately lowered, so that temperature control is difficult. Was. Also, there were cases where desired temperature control could not be performed. In particular, high temperatures could not be maintained only by the heat source using steam. Furthermore, it took a long time to raise the temperature only by the heat source using gas.

[0005] Second, considering the heat transfer, the material of the pot is reduced to 1
Attempting to form a high-conductivity material using only one type of material tends to result in an expensive pot.
Further, when only one kind of material is considered, there are various problems such as a material that easily rusts and a material that easily corrodes.

Third, when waiting for the temperature to drop after heating the food, it took a very long time for the temperature to drop naturally. In particular, when stir-fried, when the inside of the heated side began to burn, sometimes it was necessary to lower only the temperature of the burnt side to prevent burning, but it was not possible with conventional pots . An object of the present invention is to solve such a problem.

FIG. 1 is a sectional view of a pot according to a first embodiment of the present invention, FIG. 2 is a sectional view of a pot according to a second embodiment of the present invention, and FIG. 3 is a third embodiment of the present invention. It is sectional drawing of the pot which concerns on a form.

(First Embodiment of the Present Invention) First, in FIG.
The pan according to the first embodiment of the present invention will be described. As is apparent from these figures, in FIG. 1, reference numeral 11 denotes a pan having a flat bottom surface, a cylindrical shape, a vertical rising portion, and a substantially U-shaped cross section at the center. I have. Also,
The pan 11 is formed of two kinds of materials, one lower body 11a and the other upper body 11b above the jacket 52, with the junction 11z at the upper part of the jacket 52 as a boundary.

In this case, as the two kinds of materials, iron, stainless steel, a multi-layer of iron and stainless steel, copper and the like can be considered.
When it is disposed on the side a, a material having high thermal conductivity comes into contact with all the heat sources 52, 72, 77, and the pot 11 is very easy to transmit heat.

Incidentally, as one example, one having a multi-layer of iron and stainless steel on the side of one main body 11a and having stainless steel inside and using the other main body 11b with stainless steel, As an example, one using copper on one main body 11a side and using stainless steel on the other main body 11b side can be considered. Naturally, the joint 11z
This is the welding line when one main body 11a and the other main body 11b are connected.

A nozzle 72, which is a heat source 72 by gas, is connected to a gas pipe 71 below the pot 11, and an outer nozzle 77, which is a heat source 77 by gas, is connected to a gas pipe 76.
Is connected to In this case, although not specifically shown, the gas pipe 71 and the gas pipe 76 are separately controlled, so that the gas flow rate (thermal power) can be changed separately.

On the other hand, in a vertically raised position on the side surface of the pot 11, a jacket 5 which is a heat source 52 by steam is provided.
2 are arranged. Here, the jacket 52 communicates with both the water pipe 51 and the steam pipe 61 via the junction pipe 55. In this case, when supplying water and steam,
One or both of the flow rate and pressure can be changed. Naturally, water and steam can be arbitrarily selected, and can be flowed at the same time. In some cases, it is possible to supply water and steam at desired temperatures.

The jacket 52 is provided with a drain pipe 91 for draining water accumulated inside.
Further, on the extension of the jacket 52, a heat source 7 by gas is provided.

Thereafter, the gas is supplied to the various nozzles 72 and 77 which are the heat sources 72 and 77 by the gas to ignite, and at the same time, the steam is supplied to the jacket 52 which is the heat source 52 by the vapor.

As described above, by using two heat sources, that is, the heat sources 72 and 77 by gas and the heat source 52 by steam at the same time, the temperature can be reduced to 100 ° C. in a very short time of 25 to 30% compared to when only the gas is used as the heat source. When the temperature rises, the water in the pot boils, and the temperature in the pot rises to 100 ° C. in a short time of 75 to 80% as compared with the case where only steam is used as a heat source.

Further, in addition to the effect of boiling in a short time, an effect of securing a high-temperature heat source by using gas can be obtained. In this case, the two-system heat sources 72 and 77 using gas and the heat source 52 using steam can be controlled to open and close separately or increase or decrease the flow rate.
The water accumulated in the jacket 52 can be drained by a drain pipe 91.

Here, the pot 11 is heated from the lower part by the heat sources 72 and 77 by gas with strong thermal power.
Since a material having high thermal conductivity is provided on one main body 11a on the lower surface of the device, a strong thermal power from the lower portion can be easily transmitted, and the heat can be used efficiently. Has become.

On the other hand, if the food is boiled to some extent and then the food is scorched from the upper side of the pot in order to boil it for a long time, water is supplied to the jacket 52 which is a heat source 52 by steam. It became possible to cool the part and boil it down while preventing burning.

(Second Embodiment of the Present Invention) Next, a pot according to a second embodiment of the present invention will be described with reference to FIG. As is clear from these figures, in FIG. 2, reference numeral 12 denotes a pan, the bottom of which is a part of a sphere, a cylindrical shape having a vertical rising portion, and a center section substantially U-shaped.

In this case, the two types of materials may be exactly the same as those of the first embodiment. However, if a material having a higher thermal conductivity is disposed on one side of the main body 11a, a heat source by gas The heat transfer to the heating from 72 is quick and effective. As one example of a specific material of the one main body 12a and the other main body 12b, the same material as that of the first embodiment can be considered. Naturally, the joint 12z serves as a welding line when the one main body 12a and the other main body 12b are connected.

The water in the pan boils, and the temperature in the pan rises to 100 ° C. in a much shorter time than when only steam is used as the heat source, and the water in the pan boils.

Further, in addition to the effect of boiling in a short time, an effect of securing a high-temperature heat source by using gas can be obtained. In this case, the heat source 72 by gas
The two heat sources 53 and 57 using steam can be individually controlled to open and close and increase or decrease the flow rate.
The water collected in the jackets 53 and 57 can be drained by drain pipes 91 and 96.

Here, the lower portion of the pot 12 is heated by a heat source 72 by gas with a strong thermal power, and a material having a high thermal conductivity is disposed on the one main body 12a side of the lower surface of the pot 12. Therefore, the strong thermal power from the lower part is easily transmitted, and the heat can be used efficiently.
