(A) shows the state before the foodstuff is put into the oil, (b) shows the state in which the food is put in, and (c) shows the state in which the oil is drained. The state which takes out a fried foodstuff from a deep-fried basket is shown. (A) shows an example of a continuous manufacturing apparatus, (b) shows a cross-sectional view taken along line AA, and (c) shows a cross-sectional view taken along line BB. 2 shows a structural example of a superheated steam generator.

An example of the structure of the apparatus for producing fried food according to the present invention will be described below with reference to the drawings.
FIG. 1 schematically shows the structure, and the flow of fried cooking is shown in FIGS.
The example shown in FIG. 1 shows an example of a fryer cooker type, and has an oil tank 13 for storing cooking oil 15.
The heating means 13 is for heating the cooking oil (hereinafter simply referred to as oil) 15 to a cooking temperature of 160 to 220 ° C., and may be of the electric heater type shown in FIG. Gas heating or heat transfer heating.

At the upper part of the oil tank 11, an enclosure 12 covered with a cover member is formed.
The enclosure is made of stainless steel or the like, and has a structure in which the foodstuff 30 can be put in and out of the deep-fried basket 14 for deep-fried cooking.
In the present embodiment, an example in which the openable and closable lid portion 12a is provided on the upper portion is provided, but the openable and closable portion and the openable and closable structure are not limited.
As shown in FIG. 2 (c), the surrounding portion 12 is large enough to form an oil drainage space so that the frying basket 14 can be drained.
A superheated steam generator 20 for spraying and supplying the superheated steam V to the inside of the enclosure 12 is provided.
Although not shown in FIG. 1, a control unit such as a temperature controller and a timer is provided.

Since a prototype was manufactured and the fried chicken was cooked and evaluated, the flow of cooking will be described based on FIG.
The fried basket 14 has a mesh-shaped cage portion 14a made of stainless steel, and a handle portion 14b which stands upright from the cage portion 14a and has an upper end bent into an L-shape.
The oil 15 was heated to about 200 ° C., and the dry steam V superheated to a temperature of 250 to 400 ° C. by the superheated steam generating means 20 was sprayed and supplied into the enclosure 12.
When the temperature inside the enclosure was measured, it was about 150 ° C.
It is in a dry state, so-called steam is not generated at all, and only a very small amount of superheated steam needs to be supplied.
As shown in FIG. 2 (a), the lid 12a was opened, the deep-fried basket 14 containing the ingredients 30 was put into the oil, and the cooking with the oil was performed.
The superheated steam suppresses the volatilized oil from becoming hot, and also prevents contact with oxygen in the air.
In addition, the moisture generated from the food is also expelled to the outside by the superheated steam, and the dissolved oxygen is reduced to a minimum.
Next, as shown in FIG. 2C, while the lid 12a was closed, the frying basket 14 was lifted above the oil level 15a, and was left for a while in the oil draining space provided inside the enclosure 12.
Even in this state, since the inside of the enclosure 12 is filled with the superheated steam, the oxidation of oil during oil drainage is suppressed.
Thereafter, as shown in FIG. 3, the lid 12a was opened, the fried basket 14 was taken out, and the foodstuff 30 was taken out.

In the deep-fried chicken cooking, the taste was compared by changing the time of putting in oil and the time of draining oil.
A comparison was made between 4 minutes into the oil and drained for 2 minutes, and 2 minutes into the oil and drained for 4 minutes. The one was more juicy.
It was found that this not only suppresses the oxidation of oil in a reducing atmosphere at normal pressure due to superheated steam, but also affects the taste.
For example, foodstuffs may be pre-treated with superheated steam prior to pouring into oil.
In addition, although such cooking was repeated, the inside of the enclosure 12 was not stained and remained clean, and almost no change in the color of the oil was observed.
When the fish was fried, the smell peculiar to the fish had disappeared.

FIG. 4 shows an example of a continuous manufacturing apparatus.
This embodiment is of a tunnel type in which openings 12b and 12c are provided on both sides of the enclosure 12.
As shown in FIGS. 4B and 4C, superheated steam is supplied into the inside, so that the inside has a reducing atmosphere in which the oxygen concentration is kept low while the openings 12b and 12c are provided on both sides. .
When the food material 30 is placed on the mesh-shaped conveyor 16, the food material 30 is put into the oil tank 11, then continuously passes through the oil draining unit 17, and is carried out to the outside, so that the fried food can be continuously cooked.
The method of transporting the foodstuffs 30 is not limited to a conveyer method, such as a method in which a basket containing foodstuffs is fed into oil while being transported by a chain.
FIG. 4 shows an example in which an oil drain 17 is provided separately from the oil tank 11, but this part may be integrated with the oil tank 11.

FIG. 5 shows a structural example of the superheated steam generating means 20 used in the present embodiment.
The superheat generator used for the superheated steam generation means 20 is not limited to this, but the present embodiment is compact.
The inside has an L-shaped structure, stores water on the lower side, and serves as a steam generating section 22 for generating steam by a heater 22a. The steam generated from this portion is heated by an overheating heater 23a on the upper side. , An overheating portion 23 which overheats to a temperature exceeding 100 ° C.
The superheated steam is sprayed from the supply port 21 to the inside of the enclosure.
Although the amount of water decreases due to the generation of superheated steam, the water is supplied little by little from the supply unit 24, and when the water reaches a predetermined water level, the water flows out from the overflow port 26 of the sub tank 25.
This eliminates the need for an ON-OFF operation valve and a supply pump for supplying water, and also allows a necessary amount of water to be continuously supplied, so that a change in water temperature unlike the ON-OFF control does not occur. Superheated steam can be obtained stably.
