Disclosed are a food sterilizing device and a food sterilizing method capable of evenly and uniformly steam sterilizing food materials inside a container. Specifically, a device (10) that steam sterilizes a rice filled container supported by a retainer (11) includes a nozzle unit (20) attached to an upper chamber (13). A steam guide (23) having a predetermined height and a predetermined closed shape formed on a nozzle base (21) forms a substantially closed steam chamber (25) between the nozzle base and the lower surface of the upper chamber. A nozzle holder (24) disposed below the nozzle base substantially closes the opening of the container when the upper and lower chambers are in close contact with each other. Steam nozzles (31) passing through the nozzle holder so as to allow the steam chamber and the inside of the container to communicate with each other protrude upward from the nozzle base and open at a predetermined height, and at the same time, the lower ends thereof protrude downward from the nozzle holder so as to extend close to the bottom of the container. With this, steam introduced into the steam chamber is gushed from the nozzles into the container. Hot water included in the steam is drained through an opening (26) in the vicinity of the bottom surface of a partition (22). |
