That is, the rice cooking pot 2 and the pot lid 4 are transferred from the heat buffering section 73 to the rice cooking pot temperature adjusting section 80 and conveyed to another conveyer. By using separate conveyors 3, it is possible to prevent heat from flowing from the washing section 72 to the rice cooker temperature adjusting section 80 via the washing conveyers 3a and 3b. Even if the rice cooking pot temperature adjusting section 80 is compactly arranged adjacent to the washing section 72, the influence of the heat from the washing section 72 is suppressed, and the temperature of the rice cooking pot 2 can be adjusted efficiently.

In the rice cooker washing device 70, a waterproof plate 75 is installed between the upper conveyors 3a, 3c and the lower conveyors 3b, 3d. The waterproof plate 75 is installed over the whole area from the washing part 72 to the rice cooking pot temperature adjusting part 80, and is configured so that the water washed in the upper rice cooking pot 2 does not splash on the lower pot lid 4. - 特許庁Further, strainers (not shown) are provided at a plurality of locations under the waterproof plate 75 so that the water flows down into the tank T below via the strainers, so that dirt washed off from the rice cooker can be collected.

The waterproof plate 75 of the present embodiment is installed over the entire area from the washing section 72 to the rice cooker temperature adjusting section 80, but it may be installed only in the washing section 72, for example. Further, the waterproof plate 75 may be configured to be gently inclined in one of the directions perpendicular to the conveying direction of the rice cooker 2 .

As described above, the rice cooking pot cleaning device 70 of the present embodiment is configured such that the space of the heat buffering section 73 prevents heat from flowing from the cleaning section 72 to the rice cooking pot temperature adjusting section 80, so that the temperature of the rice cooking pot cleaning section 72 and the temperature of the rice cooking pot are different. The rice cooking pot temperature adjustment unit 80, which is significantly different, can be integrally formed adjacent to the washing unit 72, so that the rice cooking pot washing device 70 can be made compact and the rice cooking system 1 can be installed in a space-saving manner.

Furthermore, in the rice cooking pot cleaning device 70 of the present embodiment, since the rice cooking pot temperature adjustment unit 80 and the cleaning unit 72 are integrally configured, the rice cooking pot 2 is cooled to about room temperature before the rice cooking pot cleaning device is operated. Since it is carried out from 70, it becomes possible to dispose the subsequent grain input unit 10 nearby, and the rice cooking system 1 can be installed in a space-saving manner.

Furthermore, according to the rice cooking system 1 of the present embodiment, since the temperature of the rice cooking pot 2 is adjusted in the rice cooking pot washing device 70, after being carried out from the rice cooking pot washing device 70, a predetermined amount of grains and a predetermined amount of water are added. Even if the rice is put in, the grains and water are not affected by the heat of the rice cooker 2, and the rice can be cooked in a stable temperature state. Since the temperature in the rice cooker 2 is stabilized, the quality of cooked rice can be stabilized.

In addition, in the first embodiment of FIG. 1, the rice cooking pot cleaning device 70 and the rice cooking pot temperature adjusting unit 80 are separated from each other so as to sandwich a space, and are formed as separate bodies via the conveyor 3. Each of the cleaning device 70 and the rice cooker temperature adjustment unit 80 has the above-described configuration. In this configuration, a large installation space is required from the rice cooking pot cleaning device 70 to the rice cooking pot temperature adjusting unit 80, but the inflow of heat from the rice cooking pot cleaning device 70 to the rice cooking pot temperature adjusting unit 80 is effectively prevented. (or completely shut off).

In the first and second embodiments, grains are immersed in water in advance in the immersion tank 35 before being put into the rice cooker 2. A grain soaking part may be provided, and the grains may be soaked in the rice cooker 2 after the grains are put in. For example, a three-dimensional immersion device (not shown) in which conveyors are formed in multiple stages is provided in the grain immersion section, and the rice cooker 2 filled with grains and water before being immersed is conveyed sequentially from the upper conveyor to the lower conveyor. By doing so, grains can be immersed in the rice cooking pot 2 while the rice cooking pot 2 is being transported.

In this case, since the rice cooking pot 2 is previously cooled to about room temperature by the rice cooking pot temperature adjusting unit 80, the grains can be cooked without being affected by heat, such as by immersing the grains while the rice cooking pot 2 is still hot. It can be immersed at an appropriate temperature while still at room temperature.

Furthermore, in the first embodiment and the second embodiment, grains are soaked at room temperature, but it is also possible to soak grains at a low temperature of 10 ° C. or less using water cooled to 10 ° C. or less (cold water). It is possible. For example, the immersion tank 35 may be cooled to about 4° C. by a cooling jacket or the like, and grains may be immersed in cold water in the immersion tank 35 .

Also, when grains are soaked in the three-dimensional soaking apparatus, the grains can be soaked at a low temperature. For example, by surrounding the three-dimensional immersion device with a cooling chamber and setting the inside of the cooling chamber to a low temperature (approximately 4°C), it is possible to immerse grains in cold water for a predetermined time while transporting the rice cooker 2 in the cooling chamber. . In this case, if cold water of about 4° C. is introduced as the immersion water, the immersion in the cold water can be performed more quickly. Soaking the grains at such a low temperature further improves the quality of the cooked rice.

When immersed in the cooling chamber, the rice cooking pot 2 is cooled to about room temperature by the rice cooking pot temperature adjustment unit 80, so the rice cooking pot 2 is not conveyed to the cooling chamber while still having heat, and is conveyed into the cooling chamber. Since the rice cooker 2 that has been heated also cools down to a low temperature in a relatively short time, the cooling load on the cooling chamber can be reduced and the grains can be immersed in cold water for a longer time.

In addition, if the temperature setting of the rice cooking pot temperature adjustment unit 80 is changed to a low temperature and the rice cooking pot 2 is cooled to a low temperature of 10° C. or less (for example, about 4° C.) in advance, the cooling load is further reduced, It becomes possible to soak the grains in cold water more effectively from the start of soaking.

In the first embodiment and the second embodiment, the water supply unit 20 is on the rear stage side of the grain input unit 10, but if it is the rear stage of the rice cooker temperature adjustment unit 80, the order of input is limited to this. Instead, it may be located on the front stage side of the grain charging unit 10 and water may be supplied before the grain is charged.

In the first embodiment and the second embodiment, the temperature of the rice cooking pot 2 after spraying the normal temperature water is not measured, but the temperature of the rice cooking pot 2 is reduced to the temperature of the normal temperature water in advance. The amount of injection of normal temperature water, the injection time, etc. are set. Of course, a temperature sensor for detecting the temperature of the rice cooker may be installed to check the temperature of the cooled rice cooker 2 .

It should be noted that the present invention is not limited to the above-described embodiments, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, numerical value, form, number, location, etc. of each component in the above-described embodiment are arbitrary and not limited as long as the present invention can be achieved.

INDUSTRIAL APPLICABILITY The rice cooking system according to the present invention can be applied to fields in which the temperature of the rice cooker can be adjusted and stable rice cooking quality is desired.
