BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frying device such as a tempura or a fry.

<Prior Art> A commercial fryer for frying tempura, fries, etc. is provided in Japanese Utility Model Publication No. 53-25036. This fryer has a structure in which a plurality of electric heaters arranged in parallel are horizontally provided on the bottom surface of an oil tank, and a wire net or a perforated metal plate is fixedly provided on the heater.

[0003]

[Problems to be Solved by the Invention] The above-mentioned conventional electric fryer is a heater that uses a metal plate fixed on the heater.
Even if the watt density of
The amount of heat is small and the oil near the heater surface is exposed to high temperatures.
It does not deteriorate, prevents carbonization of fried chips, and prevents oil pollution.
It is to prevent this.

In the deep-fried frying such as tempura and fried food, the quality of the product is determined by the oil temperature around the material when it is charged. In the case of mass production, when the deep-fried food is put into an oil tank, the temperature around materials such as tempura and fries sharply drops. Especially in the case of deep-fried foods with a high water content, the amount of heat taken is large, so it is necessary to raise the oil temperature.

In such a case, in the above-mentioned conventional electric fryer, it is necessary to raise the metal surface temperature to raise the oil temperature, but in order to raise the metal plate surface temperature, the watt density of the heater is made larger than usual. There is a need to.

When the surface temperature of the metal plate is increased in this way, the temperature of the oil in the oil tank rises. However, the temperature of the oil on the surface of the metal plate that has risen is absorbed by the deep-fried food and held at an appropriate temperature, but the oil on the heater side of the bottom surface of the metal plate becomes overheated.
This causes the oil to oxidize and the carbonization of the fried waste that settles on the lower surface of the metal plate is unavoidable, and the oil stain has not been eliminated.

An object of the present invention is to provide a frying device for tempura, frying, etc., which solves the above-mentioned problems of the prior art.

[0008]

Means for Solving the Problems The gist of the present invention for achieving the above object is to provide an oil tank in which oil having a required temperature suitable for frying is stored, and an area larger than the peripheral side surfaces on the front and back surfaces.
A block-shaped heating element with a rectangular flat part
Heating of high temperature fluid passages or electric heaters embedded in the body
The heating source heats the heating element above the oil temperature in the oil tank.
The heating means and the back surface of the heating body or the back surface and the peripheral side surface are applied.
This heating element is made of a heat insulating material
Below the oil level in the oil tank at the location where the deep-fried food is charged.
It is installed parallel to the oil surface .

[0009]

With the above construction, the surface of the rectangular flat surface of the heating element is placed in the oil tank containing the oil of the required temperature suitable for frying.
In a dish that is deep-fried by direct contact with tempura, fried food, etc., the oil temperature drop when the fried food such as tempura, fried food, etc. is added is compensated by heating above the oil temperature by a heating element and heated. The lower surface of the body is insulated from heat by a heat insulating material to prevent the oil on the lower surface side of the heating body from overheating.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is an oil tank. The oil tank 1 contains oil whose temperature is set to a predetermined temperature (for example, 150 to 180 ° C.) suitable for frying by a heating device (not shown).

2 has an area larger than the area of the peripheral side surface on the front and back surfaces.
It is a block-shaped heating body having a rectangular flat portion, and the surface of the block is below the oil level in the oil tank 1 at the portion where the deep-fried food is put .
It is installed parallel to the oil surface with the rectangular flat surface facing the upper surface . The heating source of the heating element 2 is a high-temperature fluid, an electric heater, or the like, and is heated to the oil temperature in the oil tank 1 or higher.

FIG. 1 shows an embodiment in which a high temperature fluid is used as a heating source, and 3 is a circulation pump, and a supply pipe 4 for supplying a heating liquid from the pump 3 to a heating body 2 via a heater 6.
And a return pipe 5 for returning the liquid heat-exchanged by the heating element 2 to the pump 3.

2 to 4 show the structure of the heating body 2 which uses the heating liquid as a heat source. A passage 7 through which the heating liquid flows is provided in the heating body 2, and a lower surface of the heating body 2 is provided. Is provided with a heat insulating material 8.

FIGS. 5 to 7 show the structure of the heating body 2 using an electric heater as a heat source. An electric heater 9 is embedded in the heating body 2, and a heat insulating material 8 is applied to the lower surface of the heating body 2. Has been done. The heat insulating material 8 may be applied to the lower surface and side surfaces of the heating element 2.

Since the present invention has the structure as described above, the heating element 2 installed in the oil tank 1 containing the oil set at a predetermined temperature (for example, 150 to 180 ° C.) suitable for frying.
Is heated by a hot fluid or electric heater 9.

The heating of the heating body 2 is performed by heating the fried food to the heating body 2.
It is done when throwing above. That is, when the deep-fried food is charged above the heating body 2, the oil in the oil tank 1 is lowered to the predetermined temperature (for example, 150 to 180 ° C.) or lower. The heating element 2 compensates for the decrease in oil temperature and keeps the oil in the oil tank 1 at the predetermined temperature.

When the oil is heated by the heating element 2, it is heated at a temperature higher than the oil temperature, and its heat radiation surface is the upper surface side of the heating element 2 into which the deep-fried food is put, and the lower surface of the heating element 2. Since the heat is shielded by the heat insulating material 8, overheating of the oil temperature on the lower surface of the heating body 2 is prevented. Therefore, the oil on the lower surface of the heating element 2 is not exposed to a high temperature, the oil is prevented from being oxidized, and the frying chips that settle at the bottom of the oil tank 1 are prevented from being carbonized to prevent the oil from being soiled.

Rui consists of a back surface and heat insulating material on the peripheral side.
The part where the deep-fried food is thrown with the heat body facing the upper surface.
Since it is installed below the oil level in the oil tank in parallel with the oil level , tempura, fried food, etc. are placed on the surface of the rectangular flat surface of the heating element
When the oil is deep-fed by direct contact with the
Compensation for the decrease in oil temperature caused by heating the heating element
By this, a fried product with good quality can be obtained by maintaining a predetermined temperature suitable for frying.

Further, since the oil on the lower surface of the heating body is not overheated, it has the effect of preventing oil oxidation and carbonization of the frying waste that has settled at the bottom of the oil tank to prevent oil stains. .
