The rice is sectioned, the lower shutter is opened, and the rice is dropped into two lunch boxes located below, thereby simultaneously supplying and serving the rice.

[0003]

[Problems to be Solved by the Invention] However, in the conventional cooked rice laying device, the cooked rice loosened in the loosening hopper is supplied into the weighing hopper by natural fall. Bias occurs,
It is difficult to divide the cooked rice equally, and it is also affected by the softness of the cooked rice, so that there is a problem that it is very difficult to equalize the serving amount of each lunch box.

Accordingly, the present invention is to provide a rice cooking apparatus that can equip a plurality of lunch boxes and the like located below by a branched weighing hopper with a uniform amount of cooked rice.

[0005]

In order to achieve the above object, a measuring hopper is provided below an outlet of a loosening hopper,
The measuring hopper is branched according to the number of containers such as a lunch box to be supplied at the same time, and an upper shutter and a lower shutter for opening and closing the inside of the measuring hopper are provided at intervals below in the lower part of the measuring hopper. A distribution damper capable of opening and closing each passage is provided in the middle.

Further, it is preferable to provide a rice sensor capable of detecting the rice supplied to each of the branched paths of the weighing hopper due to the effects described later.

Further, the metering hopper may be bifurcated to form a guide portion, and a distribution damper may be installed substantially at the center of the lower portion of the loosening hopper so that each passage can be opened and closed.

[0008]

As described above, according to the rice laying apparatus of the present invention, the rice is supplied from the rice cooker into the loosening hopper to loosen the rice inside, and the branch passage in the measuring hopper is provided by the distribution damper provided in the middle. By supplying the cooked rice in a state where only the supply passage is opened and the other passages are closed, the cooked rice can be sequentially supplied to the branched passages in the weighing hopper in a uniform state.
Then, with the lower shutter closed, the upper shutter is opened and closed, so that a certain amount of cooked rice is held between the upper shutter and the lower shutter. A fixed amount of cooked rice can be simultaneously supplied and served in a container such as a lunch box.

In the case where a sensor provided with a cooked rice sensor capable of detecting cooked rice supplied to each of the branched paths of the weighing hopper is used, each of the lunch boxes is detected by detecting the cooked rice by the cooked rice sensor. The amount of cooked rice supplied into each of the branched passages in the weighing hopper that supplies the containers such as the above can be made constant.

Next, when the measuring hopper is bifurcated to form a guide portion, and a distributing damper is installed at substantially the center of the lower portion of the loosening hopper to open and close each passage. By rotating the distribution damper located in the lower part of the unraveling hopper, it is possible to alternately supply cooked rice by closing one guide part and opening the other guide part of the weighing hopper.
