A high temperature food heating device, comprising:
- a heating tank comprising three tanks, which are a main tank for storing water at a temperature higher than 100° C. and a front reserve tank and a rear reserve tank respectively storing water, wherein each of the front reserve tank and the rear reserve tank has a first storage part having an opening at an upper part and a second storage part communicating with the first storage part at a lower part of the first storage part and having an opening at an upper part;
- a front reserve tank heating section for heating the water in the front reserve tank to a predetermined temperature from 90° C. to 98° C. from a vicinity of the bottom surface of the front reserve tank;
- a main tank heating section for heating the water in the main tank to a predetermined temperature from 105° C. to 120° C. from a vicinity of the bottom surface of the main tank;
- a rear reserve tank cooling section for cooling the water in the rear reserve tank to a predetermined temperature of 10° C. to 40° C. from a vicinity of the bottom surface of the rear reserve tank;
- a communication chamber for storing a pressurized gas or a pressurized liquid which acts as a heat insulating layer inside the communication chamber and communicating between a water surface of each of the second storage parts of the front reserve tank and the rear reserve tank and a water surface of the main tank through the heat insulating layer;
- a pressurized fluid supply section for supplying the pressurized gas or the pressurized liquid which acts as the heat insulating layer into the communication chamber directly to maintain a volume of the heat insulating layer, wherein the pressurized fluid supply section is connected to the communication chamber;
- a front side communication chamber communicating between the water surface of the second storage part of the front reserve tank and the water surface of the main tank and a rear side communication chamber communicating between the water surface of the second storage part of the rear reserve tank and the water surface of the main tank to serve as the communication chamber;
- and
- a container conveying section for conveying a container accommodating noodles as an object to be heated to pass through, in order, the water of the front reserve tank, inside of the front side communication chamber, the water of the main tank, inside of the rear side communication chamber, and the water of the rear reserve tank, wherein the container conveying section keeps the container in the water of the main tank between the front side communication chamber and the rear side communication chamber;
- the three tanks being provided side by side in a lateral direction,
- the front side communication chamber comprising an upper part facing downward toward at least a portion of each bottom surface of the main tank and the front reserve tank, and a frame-shaped sidewall part extending downward from the upper part, and
- the rear side communication chamber comprising an upper part facing downward toward at least a portion of each bottom surface of the main tank and the rear reserve tank, and a frame-shaped sidewall part extending downward from the upper part.
