Next, the operation of the large-sized gas-type continuous automatic rice cooker constructed as described above will be described.

When the operation is started, the rice cooker 7 containing a predetermined amount of rice washing and water is transferred one after another through the endless conveyor 1 into the rice cooker heating traveling path 1a, that is, into the heating chamber 3.

In the rice cooker 7 transferred to the heating chamber 3, a gas flame is continuously sprayed on substantially the entire bottom surface of the rice cooker 7 from the starting end of the heating chamber 3 to the vicinity of the terminal end. During the transfer time, the cooked rice cooked in the same manner as the stationary cooked rice is performed.

During the time when the rice cooker 7 passes through the terminal end of the heating chamber 3, the gas flame is discontinuously jetted onto substantially the entire bottom surface of the rice cooker 7, so that the heating amount gradually decreases. The cooked rice in the rice cooker 7 is subjected to the action of high-temperature steaming.

Thereafter, the rice cooker 7 is lifted on its lower bottom surface by the transfer device 5 so that the handle 9 can be moved to the chain conveyor 1 on the rice cooker heating path 1a.
It is lifted from 2a and transported to the exit conveyor 40 at a higher speed than the conveyor 12a.

The transfer of the rice cooker 7 to the outlet conveyor 40 is restricted by a stopper 38, and the handle 9 of the rice cooker 7 waits at the position of the movement locus of the rice cooker holding hook 26 of the steaming chain conveyor 25.

At this time, the rice-cooking holding hook 26, which rises up the vertical portion at the start end of the high-temperature steaming travel path 15 as the steaming chain conveyer 25 runs, scoops up the handle 9 of the rice cooker 7 and rises. And the middle frame 23 of the heating chamber 3

Rice in rice pot 7 for transporting the said depending on hot air or preheating the middle frame 23 to rise through the subject to the action of high temperature steaming, condensation caused by rapid cooling of the cooking pot 7
Prevention Does not cause stickiness of cooked rice due to condensed water.

The action of the high-temperature steaming is achieved by adjusting the opening of the through-hole 46 by the damper 45 and thereby controlling the heating chamber 3.
It is adjusted by increasing or decreasing the amount of hot air inside.

Each rice cooker 7 having returned to the start end in the middle frame 23 is circulated to the start end of the upper frame 20 and thereafter transferred to the end side along the horizontal direction above the outside of the heating chamber 3. At the terminal end side, the stopper 3
8, since the holding hook 26 placed on the rotating outlet conveyor 40 at the rear and descends away from the handle 9, the rice cooker 7 is thereafter discharged outward. Then, the holding hook 26 turns around the first sprocket 19 and moves to the high-temperature steam traveling path 15 again.

The rice cooker 7, which is transferred horizontally above the outside of the heating chamber 3, is subjected to room temperature steaming by the outside air.

As described above, when the rice cooker 7 containing the rice washing and water is sent to the heating chamber 3, the rice is cooked, steamed at a high temperature, and steamed at room temperature, and discharged one after another.

At this time, if a trouble occurs in the steaming travel path 2, the stopper 38 is moved to the bracket 4.
Pull out from one. At this time, the cooked rice heating runway 1a is communicated straight outward through the transfer device 5 and the outlet conveyor 40, and the limit switch 42 is turned off to run the steaming runway 2. The running chain conveyor 25 stops its operation. Therefore, the rice cooker 7 passing through the heating chamber 3 by the rice cooker heating traveling path 1a is discharged straight out from the transfer device 5 and the outlet conveyor 40 to avoid burning.
