Next, an example of the operation of the food cooking apparatus 100 will be described.
For example, cooked rice is stored in a cooked rice storage device (so-called rice hopper or the like), and the cooked rice is stored in a container 180 such as a bowl or a bowl from the cooked rice storage device by the operation of the cook 1 (operator or the like).
As shown in FIG. 1, the main body 100B of the food cooking apparatus 100 is arranged on the countertop 500.
The cook 1 moves the container 180 containing cooked rice to the cooking position of the food cooking apparatus 100 (below the spout where superheated steam is ejected) (see FIG. 10 and the like).

The food cooking apparatus 100 is provided with a protrusion 161 and a concave portion 160 at a position above the cooking position (position where the container 180 is arranged).
For example, when a cook (operator or the like) lifts a container 180 such as a bowl containing food f such as cooked rice upward, the detection member 120B moves upward. The upper limit position of the lower end of the detection member 120B is defined so that, for example, the food f such as cooked rice contained in the container 180 comes into contact with the lower surface or the lower end having a concave cross section of the concave portion 160 ( 11 and 12).
In the present embodiment, the upper limit position of the lower end of the detection member 120B is defined to be higher than the lower end of the detection member 120B by a predetermined length.
When the detection unit 120 detects that the plate-shaped member 120Bg is located at an upper position and the operation button BT is turned on, the control unit 150 ejects the ejection port 161h of the protrusion 161 and the ejection of the concave portion 160. Control is performed so that superheated steam is ejected from the outlet 160h, and the cooked rice is evenly heated by the superheated steam from the inside and the outside of the cooked rice (see FIG. 12A).

Further, the superheated steam ejected from the spout 161h of the protrusion 161 and the spout 160h of the concave portion 160 fills the container 180 such as a bowl, and the cooked rice can be heated evenly.

Specifically, when superheated steam comes into contact with cooked rice (food to be heated), it condenses and at the same time supplies moisture and latent heat to cooked rice, so that cooked rice can be heated rapidly.
In addition, the superheated steam whose temperature has dropped due to heating the cooked rice moves out of the container through the opening at the top of the container 180, and at the same time, a new high temperature is generated from the spouts provided at the protrusion 161 and the concave portion 160. Since the superheated steam is continuously ejected onto the cooked rice in the container 180, the cooked rice contained in the container 180 can be heated evenly in a short time.

The control unit 150 of the food cooking apparatus 100 controls to stop the ejection of superheated steam after heating the food f for a predetermined time (for example, 2 to 10 seconds).
Then, as shown in FIG. 12B, the container 180 is lowered by the cook 1 (operator or the like) so that the protrusion 161 of the food cooking apparatus 100 and the concave portion 160 are separated from each other by a predetermined distance or more. .. The cooked rice in the container 180 is in a state like freshly cooked.
The control unit 150 of the food cooking device 100 controls to stop the ejection of superheated steam when the detection unit 120 detects that the container 180 or the food is separated from the food cooking device 100 by a predetermined distance or more. do.
Specifically, for example, when the detection unit 120 detects that the detection member 120B is lower than the upper limit position, or when the detection member 120B detects that the detection member 120B is located at the lower limit position, the control unit 150 superheats steam. Control is performed so as to stop the eruption of water vapor.

As described above, the food cooking apparatus 100 according to the embodiment of the present invention performs food cooking using superheated steam. The food heating cooking apparatus 100 is provided with a superheated steam generating unit 110 that generates superheated steam and a spout 161h that is provided so as to be insertable into a food (rice or the like) to be heated and ejects superheated steam from the superheated steam generating unit 110. It has a protrusion 161 provided with a portion 161 and a concave portion 160 provided with a surface (lower surface or the like) capable of contacting the food f. The concave portion 160 has a spout 160h on a surface (lower surface or the like) that can come into contact with the food f to eject superheated steam from the superheated steam generating portion 110. In the above embodiment, the concave portion 160 has a protruding portion 161 protruding downward in the central portion.
Superheated steam is ejected from the spout 161h of the protrusion 161 inserted into the food f (rice or the like) to be heated and the spout 160h provided on the contact surface (lower surface) of the concave portion 160 to spout the food f. By simultaneously heating from the inside and the outside of the food f, it is possible to provide the food cooking apparatus 100 capable of evenly heating the food f in a short time with a simple structure. The food cooking apparatus 100 does not have a cooking room and has a simple structure.
