In order to clarify the positioning of the present invention, a conventional rice cooking method will be described below using a process flow including a stage of supplying rice from a rice grain manufacturer. First, as method A, there is a general method adopted in the small-scale restaurant industry and the like. This consists of seven steps: processing of rice, packing of a measuring bag for one pot, delivery, washing, dipping in a dipping container, replacing with a rice cooker, and cooking rice.
Next, as method B, the automatic weighing rice cooker for business use and the method used in general households are: rice processing → delivery → weighing for one pot → rice washing → dipping in a rice pot →
It consists of 6 steps: cooking rice. The C method that follows is the method used in large-scale rice cooking plants, which includes rice milling → delivery → washing → dipping → weighing one pot →
It consists of 7 steps of replacing the rice in the rice cooker → cooking rice. The D method is a method in the food service industry that uses non-washed rice that has been debranched in advance so that a rice washing step is not required.
It consists of 7 steps: delivery → soaking → replacing with rice cooker → cooking rice. Finally, as the E method, when the above-mentioned unwashed rice is used at home, rice polishing processing → unwashed processing → delivery → weighing one pot → lightly washing rice in a pot → dipping →
It requires 6 steps of cooking rice (because there is an unsanitary feeling to rice bins, etc., even though the rice is not washed).

There are four types, D, and each has various problems in terms of variations in rice cooking. That is, the hardness of cooked rice is always required to be constant in the food service industry, etc., but in reality, it sometimes becomes softer for some reason.
On the contrary, it gets harder, and customers make complaints each time. Therefore, in the food service industry and the like, how to cook rice with a certain hardness is difficult. However, no matter how much the ratio of rice and water is constant, the hardness becomes uneven, and the cause is unknown.

まうという問題点が有った。Then, when the present inventor investigated the cause that rice having a certain hardness could not be cooked even when the ratio of rice and water was constant, the following facts were discovered. In the past, it was found that even though the rice and water were intended to be cooked at a fixed rate, they were not. This measures a pot of rice before going through the washing and dipping steps,
It has been found that the cause is that the number increases and decreases each time the steps and the steps between steps are changed, and the rate of increase and decrease is not constant. That is, if the rice is washed and soaked after being weighed, (a) the amount of rice washed away with the goat juice (there is a difference of 1% to 5%) and The difference between the residual amount of this time and the residual amount of this time, and (c) the difference between the amount that was previously adhered to the immersion container and the residual amount of this time during dipping are This is because the amount is adjusted. That is, the amount of spillage during rice washing is indefinite depending on the time, and the workers are busy, so there is no possibility that the rice adhering to the water will be completely recovered when replacing the rice at each process, and no one is I think it's a slight amount, and I'm not aware that it affects the state of cooked rice. In the case of the method C, the amount of water present between the rice grains changes depending on how much water is drained, and the amount of water intervening between the rice grains changes depending on the degree of draining, and the actual amount of rice changes compared to other methods. As described above, in the conventional rice-cooking method, although the substantial amount of rice changes depending on the condition of the rice or the rice-washing machine, the mood of the worker, the condition of the dipping container, the condition of the drainage, etc. There was a problem in that the rice after the rice was cooked had hard and soft variations when the rice was cooked by adding the water.

すると、しゃもじによる移し替えが不要となる。In the commercial rice cooking method of the present invention, one pot of non-washed rice and water for cooking is put into the rice cooker to start cooking. Therefore, once the non-washed rice and water for cooking are metered into the rice cooker. After that, you can start cooking rice without replacing them. Further, since the non-washed rice and the water for cooking rice are respectively metered directly into the rice cooker to start the rice cooking, the rice cooking is immediately started without the dipping step using a special container as in the conventional case after the metering. It will be. Therefore, in any case, the non-washed rice and the water for cooking rice are not added or reduced after weighing, and a constant ratio is always maintained. In the rice cooker used for this rice cooking method, a rice water supply means provided near the outlet of the rice storage tank and a single or multi-stage rice cooker storage drawer shelf provided below the rice storage tank. In addition to the above-mentioned configuration, a rice cooker housed in the rice cooker storage drawer is provided, and when the rice cooker storage drawer is in a substantially half-opened state, the dispensing opening of the weighing dispensing means and the water supply means Positioning the water supply port directly above the rice cooker allows the once-measured raw rice and water for cooking to be directly charged into the rice cooker as it is when the drawer shelf is in a substantially half-opened state. Further, a rice storage tank having a metering and dispensing means, a water supply means provided near the dispensing opening of the rice storage tank, a multi-tiered rice cooker storage drawer provided below the rice storage tank, and the rice cooker storage A rice cooker comprising a rice cooker housed in a drawer shelf, wherein a rice and water drop passage is provided in communication with the rice cooker housing drawer shelf in the up-down direction, and a rice dispensing port from the weighing and dispensing means and The characteristic configuration in which the water supply port from the water supply means is arranged in a positional relationship facing the opening of the drop passage makes it possible to directly put a measured amount of one pot of raw rice and cooking water into the rice cooker. Especially, when a drop passage for rice and water is provided together with a plurality of drawers for storing rice cookers, it is easy to meter raw rice and cooking water into the rice cookers located in the lower shelf. In addition, an operation panel that can be electrically connected to the control unit of the rice cooker stored in the rice cooker storage drawer is provided, and a timer function is provided on the operation panel to receive a heating end signal from the rice cooker, By providing an alarm function for emitting a steaming completion notification sound after the elapse of the set time of the timer, it is possible to automatically notify the worker of the end of the rice cooking process. Holding the rice storage tank via the load cell and storing it in the tank cover member can contribute to protecting the raw rice in the tank from the high temperature of the surroundings, and also has both the functions of storing rice and weighing. I will let you. When the rice cooker storage drawer is fully closed, if a cover member with heat insulating material is provided around the ceiling and in the space above the center of the height of the stored rice cooker, heat loss from the cooker will be lost. In addition to drastically reducing fuel consumption, heat dissipation of the lid of the pot can be prevented, so that water drops will not drop due to dew condensation on the inside of the lid, and the steaming process can be performed at high temperature to cook delicious rice. It will be possible. Further, the heating power of the pilot fire can be applied to the rice cooker to provide a heat-retaining jar function. If a heat-retaining jar is additionally provided and the inner pot of the rice cooker and the inner container of the heat-retaining jar are common parts, transfer by scooping is unnecessary.

Rice can be cooked without the dipping step by lengthening the length of the rice, or turning off the heating 5 to 7 minutes after starting the rice cooking, leaving it for 5 to 7 minutes and then reheating. When using a multi-stage rice cooker having a plurality of shelves, the rice cook order is displayed. As a result, a large amount of rice can be cooked in a small space, and the rice cooking order does not get complicated. In addition, the heat-insulating function is imparted to the rice cooker by the cover provided with the heat insulating material, and the cooked rice is kept warm while being taken out to the plate. Alternatively, it is possible to wait in the storage shelf until the attached heat retaining jar is empty. In that case, the inner pot of the rice cooker is also used as the inner container of the heat retaining jar, and the inner pot of the steamed rice cooker is held by hand and placed in the heat retaining jar. Therefore, the work of transferring rice with rice scoop is unnecessary. When the rice is consumed and the inner pot and the inner container of the heat insulation jar are emptied, the rice is boiled in the rice cooker. As a result, the adhering matter is peeled off, and the effect of washing the pot is produced by simply removing the adhering matter, and the next rice can be cooked. Also, this washing pot only needs to be done once, and the time for filling water is not necessary.

良い。Next, the details of the present invention will be described based on specific examples. The rice cooking method of the present invention is to start rice cooking by suddenly metering raw rice and rice cooking water that have been debranched beforehand without the need for washing with water into a rice cooker. That is, the amount of rice for one kettle and the corresponding amount of water for cooking rice are put into the rice cooker after being measured by a measuring device or a flow meter, respectively, and the amount once measured by the measuring device is put into the rice cooker. There is a method and a method of stopping the discharge when a predetermined amount is reached while discharging into the rice cooker through the flow meter. And in any case,
Add the amount of rice and water for cooking rice to the rice cooker as they are without changing the measured amount. This is because the conventional rice washing process and the dipping process in a dipping tank can be omitted, and so-called "non-washed rice" that can be cooked without the need for washing rice is used. This non-washed rice means, for example, dry washed rice described in Japanese Patent Application Laid-Open No. 2-242647 according to the present invention, refined rice that has been previously milled and debraned as in Japanese Patent Application No. 5-188702, etc. Rice that has been debranched with water or other means and does not need to be washed before cooking.
The term "cooking water" refers to the amount of water consumed for cooking rice as it is. Then, when the raw rice and the cooking water are metered into the rice cooker and the rice cooking is started without passing through the dipping process,
The total cooking time can be shortened. To do this, use a non-washed rice by slightly reducing the heating power and lengthening the cooking time by 5 to 10 minutes, or by turning off the heating 5 to 7 minutes after starting the cooking and leaving it for 5 to 7 minutes and then reheating it. However, rice can be cooked without the dipping process.
If it is necessary to soak it here, it can be done in a rice cooker.

容器と兼用になっているからである。The rice cooking method of the present invention using such a rice cooking device is roughly as follows. First, the canopy 33 is removed, and the non-washed rice that the present inventor has already proposed is put in. Since the rice storage tank 5 containing unwashed rice is supported by the load cell 37, the weight of the rice is displayed on the operation panel 31 electrically connected to the load cell 37. , A notification sound is emitted. Next, when one of the upper stage and the lower stage, for example, the lower stage handle 25 is pulled and opened halfway, the rice cooker 11 that has been stored reveals its face. Therefore, when the lid 53 of the rice cooker 11 is removed and the button 77 of the operation panel 31 is pressed, the solenoid 41 and the water amount controller 61 are energized, and a preset amount of raw rice is discharged from the dispensing port 19. Discharge down. at the same time,
Alternatively, if necessary, the amount of rice cooking water suitable for the amount of raw rice (1.3 to 1.5 times the amount of rice water) may be discharged from the water supply port 21 either before or after the operation. Is the inner pot 49
It is thrown in. However, in this case, the supply mode of raw rice and cooking water is slightly different between the upper case and the lower case. That is, in the case of the upper stage, the raw rice and the water for cooking rice fall in the open state, whereas in the case of the lower stage, the raw rice and the rice cooking water dropping from the water supply port 21 and the water supply port 21 both fall in the upper stage. It is thrown into the inner pot 49 at the lower stage through the drop passages 15 and 17 provided between the outer plate 73 and the inner plate 75 of the drawer shelf 9a. Further, since the rice grains are sandwiched when the shutter 43 is closed, a gravity type closing device (not shown) is provided at the payout opening 19 in order to prevent the rice grains from falling down. further,
To prevent operation mistakes when discharging raw rice or cooking water, an electrical interlock is provided so that one of the drawer shelves is not drained except when it is in the half-opened state. In this way, when the inner pot 49 is filled with raw rice and cooking water, the lid 53
After that, the drawer shelves 9a and 9b are completely pushed down to be fully closed, and then the heating switch 63 is pushed. At this time, if necessary, the heating switch 63 may be pressed after a temporary dipping process. Then, 25 to 40 minutes after pressing the heating switch 63, the sensor of the rice cooker 11 is activated to automatically turn off the heating switch 63, and the heating process is completed. There are the following three types of this heating process depending on the setting method on the operation panel 31 in advance. Method (1): Moderate weak heating by switch ON → Automatic extinguishing after about 30 minutes Method (2): Normal heating by switch ON → Automatic extinguishing after about 6 minutes → Automatic heating about 6 minutes after automatic extinguishing →
Automatic fire extinguishing after automatic heating for about 13 minutes (3): Timer energization (immersion) by turning on the switch → Automatic normal heating after about 20 minutes → About 20 after starting heating
Automatic fire extinguishing in minutes (soaking time may be short because it is warm depending on the pilot fire) In any of the above cases, the timer will start at the same time as the automatic fire extinguishing is completed, and 15 minutes depending on the pilot fire and the residual heat
After entering the steaming process for 20 minutes, when the steaming process is completed, a notification sound of rice cooking completion is emitted. Then, the operator who hears the notification sound pulls the handle 25 of the lower drawer shelf 9b to fully open it, then opens the lid 53 and loosens the rice in the inner pot 49 with a scoop or the like. After that, it can be placed on a plate as it is, or the handle 55 of the inner pot 49 can be lifted and placed in a separately prepared heat-retaining jar. This is because the inner pot 49 of the rice cooker 11 also serves as the inner container of the heat retaining jar, as shown in the following figures.

可能としたものである。The structure of the heat retaining jar 79 is shown in FIG. In the example shown in the figure, a hot plate type heat retention heater 91 is provided at the bottom of the outer peripheral box body 87 accommodating the heat insulating material 85 between the inner body 81 and the outer body 83 via a holding spring 89.
Further, a lid heater 95 is provided inside the outer lid 93, and the inner pot 49 of the rice cooker can be housed as an inner container.

のである。If the lid 53 is placed on the inner pot 49 and the drawer shelves 9a and 9b are fully closed again without being housed in the heat retaining jar 79, the heat source of the originally ignited pilot fire and the rice cooker 1
The function of the heat-retaining jar 79 also occurs due to the heat-retaining effect of being covered by the cover member 45 provided with the heat-insulating material provided in the upper half part of 1. The cover member 45 not only produces the same effect as the heat retaining jar 79, but also reduces the heat radiation loss of the rice cooker 11 during rice cooking and prevents the heat radiation of the lid 53. The dripping due to dew condensation from the inside disappears and the rice is cooked deliciously.

When 3 is taken and the heating switch is turned on in the rice cooker 11 to perform empty heating, heating is automatically stopped after about 2 minutes. As a result, the cooked rice residue in the pot is solidified and dried, and can be easily taken out and removed with a rice scoop or the like. Therefore, the next rice can be cooked without washing with water or hot water.

１７が位置するようにしておけば良い。As a second embodiment, FIG. 7 shows a case where the present invention is applied to large-scale rice cooking. In the example shown in the figure, a plurality of rice cookers are accommodated and connected by a chain-shaped rice cooker accommodating means. In this figure, the non-washed rice is stored in the rice storage tank 101, and when the empty rice cooker 105 is located below the supply pipe 107 by the weighing and discharging means 103 provided therebelow, one rice cooker 105 The amount of rice is dispensed to the rice cooker 105 through the supply pipe 107. At the same time, the water supply means 113 configured by the water pipe 109, the water meter connected to the water pipe 109, and the solenoid valve 111 measures the water for cooking one pot of rice and dispenses it to the rice cooker 105. In this way, appropriate amounts of rice and water are sequentially charged into the rice cooker 105. On the other hand, as described above, the rice cooker 105 is formed by connecting a plurality of cookers having the same shape in a chain, and moves from the right to the left in the drawing. Then, the rice cooker 105 into which the raw rice and the water for cooking rice have been charged is sequentially moved to the left, and the lid 115 is put on automatically or manually and the dipping process is started. After the dipping step, the heating means 117 by gas fire is reached and the heating step starts. After the heating step, although not shown in the drawing, the steam returns to the original position through a steaming step, a rice removing step, or a washing step. In this way, each rice cooker 105
Repeats the same process in sequence and cooks a large amount of rice. Reference numeral 119 denotes a chain-shaped rice cooker accommodating means, and its shape is not limited to this example as long as it can accommodate and connect a plurality of rice cookers 105. Further, in the present embodiment, the dipping process is described, but the dipping process may be omitted as in the first embodiment. In that case, the heating means 1 immediately after being put into the rice cooker 105.

えて機構が単純化でき、炊飯装置の低廉化が図れる。As described above, according to the present invention, the following excellent effects can be obtained. First of all, in the restaurant industry where workers are replaced, rice with a uniform hardness is always cooked regardless of who cooks it. Secondly, the whole rice cooking process is simplified, and the worker only has to open and close the drawer shelf and press the operation button, which is extremely efficient and can significantly reduce the labor cost. Third, there is no need for a rice washing machine, a soaking space, or a storage space for rice that is usually placed on the floor,
Further, since a plurality of rice cookers can be installed in the vertical direction, the space required for cooking rice can be significantly reduced, such as saving space compared to the conventional parallel arrangement. This is very advantageous in restaurants near the city because the land price is high and we want to take up a little seating space. Fourthly, water drops in the lid do not drip during steaming, and since steaming at high temperature is possible, delicious rice can be provided. Fifth, there is no need to transfer cooked rice to a heat-retaining jar or a washing pot, which can greatly contribute to labor saving and energy saving. Sixth, even when a plurality of rice cookers are connected in a chain, rice having a uniform hardness is always cooked regardless of who cooks it. In addition, a rice washing machine and a soaking space are not required, and in addition, the mechanism can be simplified and the rice cooker can be made inexpensive.
