Description

  The present invention relates to a program relating to an automatic rice cooking method.

  With the diversification and sophistication of tastes, consumer needs for cooked rice with better taste have become stronger, and microcomputer-controlled rice cooking devices have become widespread.

  Here, the configuration and operation of such a conventional rice cooker will be described.

  First, as a preparatory preparation, pre-cooking is performed to allow rice to absorb water by immersing it at a certain temperature. Next, it heats until it boils at full power, and cooks to maintain boiling with a heating output according to the amount of rice to be cooked. Then, heating is performed at a temperature that does not cause scorching at the bottom of the pan, and additional cooking is performed to gelatinize the rice.

  In addition, washing rice for separating rice bran from rice prior to cooking (Kenmai) greatly affects the taste of cooked rice and is a laborious operation. They are mainly sold.

  Here, the configuration and operation of such a conventional rice washing apparatus will be described.

  First, (a) in water-washed rice using water, the water and rice are stirred with a propeller, and (b) in anhydrous washed rice that does not use water, the surface of the rice is rubbed with a brush or the like. Separate the rice cake from the rice. Thereafter, the rice cake causing the generation of rice cake odor after cooking rice is removed as much as possible by suction or the like.

  Note that an automatic rice cooker in which such a rice cooker and a rice washing apparatus are integrated is being commercialized and sold for both commercial use and home use.

  However, when the conventional rice cooker, the rice-washing apparatus, or the automatic rice cooker was utilized, there existed a subject that the boiled-up of the expected rice could not be obtained.

  The conventional rice cooker as described above controls the heating temperature and the heating time in a series of rice cooking processes uniformly regardless of the state of the rice to be cooked. Further, the conventional rice washing apparatus as described above uniformly controls the washing time and the like in the washing process regardless of the state of the rice to be washed.

  The present inventor has come to realize that the reason why the above-described expected cooking cannot be obtained is that the state of rice such as water content is not taken into consideration in a series of rice cooking and rice washing processes.

  Moreover, the conventional automatic rice cooker as described above is merely an integration of the conventional rice cooker and the rice washing device, and the control of the heating temperature and heating time in a series of rice cooking processes and the rice washing time in the rice washing process. Etc. are completely unrelated to the control.

  The present inventor has come to realize that the reason why the cooked rice that meets the above-mentioned expectation cannot be obtained is that washed rice and cooked rice are not associated with each other.

(See FIGS. 2 and 4).

  The rice-washing plate 1223 (see FIGS. 2 and 4) is made of a stainless steel plate that conforms to food hygiene standards, and has an open top and bottom cylindrical shape. A number of punching holes (not shown) having a diameter of about 1.6 mm through which particles can pass are formed (in order to prevent fine particles from adhering to the wall surface, an appropriate electric field may be set). .

  This is the end of the detailed description of the configurations of the rice washing drum 1210 and the outer peripheral plate 1220.

  The discharge unit 1300 (see FIGS. 1 and 2) is made of a stainless steel plate that conforms to food hygiene standards, has a substantially conical shape with a slope angle of about 30 ° to prevent residual rice removal during rice removal, This means is mounted on the rotating shaft 1610 (see FIG. 2) and can move up and down. More specifically, the discharging unit 1300 (1) moves the rice at high speed along arrows Y1 to Y3 (see FIG. 2) (it is pushed to the lower part of the rice washing drum 1210 by centrifugal force due to rotation and loses its place). The rice is raised in the direction of arrow Y1 against gravity). At the time of rice washing, it is brought into close contact with the elastic sealing portion 1310 to seal the lower surface of the rice washing plate 1223 (see FIGS. 2 and 4).

  The control unit 1500 (see FIG. 1) (1) “moderate”, “normal”, “normal” according to the mode selected by the user among the three modes of “new rice mode”, “normal mode”, and “old rice mode”. The rice washing conditions of either “Solid” are automatically set, and the drive unit 1600 (see FIG. 1) is driven accordingly to cause the rice washing unit 1200 (see FIG. 1) to perform anhydrous washing, and (2) the rice cooking unit 1400 ( It is a means for making the rice cooking according to the mode selected by FIG. That is, it can be said that the control part 1500 (refer FIG. 1) has the central control part which controls both rice washing and rice cooking.

  Here, FIG. 6 which is explanatory drawing of the rice washing table for performing the rice washing in Embodiment 1 concerning the program of this invention, and description of the rice cooking table for performing rice cooking in Embodiment 1 concerning the program of this invention. The configuration of the control unit 1500 (see FIG. 1) will be described in detail with reference to FIG.

  (1) The control unit 1500 (see FIG. 1) looks at the rice washing table (see FIG. 6), sets rice washing conditions according to the mode selected by the user among the three modes described above, and the driving unit 1600 ( This is means for determining the rotation speed and rotation time of a motor (not shown) of FIG.

  In the “new rice mode”, the rice washing conditions, the rotation speed, and the rotation time are “moderate”, “slow”, and “short” in order in comparison with the standard values in the “standard mode”. Since fresh rice has a high water content, it is likely to be crushed by washing rice, and since the elapsed time after milling is short, there are few oxidized parts of the surface structure to be removed by washing rice.

  In the “old rice mode”, the washing condition, the rotation speed, and the rotation time are “steady”, “slow”, and “long” in order. Since old rice has a low water content, it is likely to be crushed by washing rice, and since the elapsed time after milling is long, there are many oxidized parts of the surface structure to be removed by washing rice, so the contents of the rice washing table as described above can be said to be appropriate.

  In this embodiment, since the vertical rotation shaft 1610 (see FIGS. 2 and 3) in the vertical direction is used, the total moving distance of rice is adjusted by adjusting the rotation speed and rotation time of a motor (not shown). It is possible to easily change the washing condition (the degree of washing) by adjusting (the number of laps of the cycle along the arrows Y1 to Y3 (see FIG. 2)).

  However, the arrow Y1 in the case where the upper inclination angle of the drum-shaped rice draining portion 1211 (see FIGS. 2 and 3) provided on the inner peripheral surface of the rice washing drum 1210 is 14 to 26 ° with respect to the vertical line. The present inventor has experimentally confirmed that the rotational speed of a motor (not shown) in which rice circulates in a cycle along Y3 (see FIG. 2) is about 600 to 2000 r / min (indicated by arrow Y2). In order for the rice to fall freely along, it is desirable that the above-mentioned inclination angle is somewhat large).

  (2) The control unit 1500 (see FIG. 1) looks at the rice cooking table (see FIG. 7), adjusts the water, pre-cooking temperature, pre-cooking time, boiling maintenance power, boiling maintenance time, additional cooking time, additional cooking power. The rice cooking unit 1400 (see FIG. 1) performs rice cooking according to the selected mode.

  The water level, pre-cooking temperature, pre-cooking time, boiling maintenance power, boiling maintenance time, additional cooking power, and additional cooking time in the “new rice mode” are “smaller” in comparison with the standard values in the “standard mode”. , “Low”, “short”, “large”, “long”, “large”, “long”. Since the new rice has a high water content, it is easy to absorb water, and the starch structure is easily swollen and gelatinized. Therefore, it can be said that the contents of the rice cooking table as described above are appropriate.

  In "old rice mode", water level, pre-cooking temperature, pre-cooking time, boiling maintenance power, boiling maintenance time, additional cooking power, additional cooking time are "large", "high", "long", "small" in order. , “Long”, “large”, “long”. Old rice has a low moisture content, so it is difficult to absorb water and the starch structure is difficult to swell and gelatinize. Therefore, the contents of the above-mentioned rice washing table are appropriate (additional cooking power, additional cooking time are “large”, “long” in order) This is because the so-called scent of old rice is reduced by adding fragrance).

  This is the end of the detailed description of the configuration of the control unit 1500.

  The rice cooking unit 1400 adjusts the water level, pre-cooking temperature, pre-cooking time, boiling maintenance power, boiling maintenance time, additional cooking power, additional cooking time according to control from the control unit 1500, and performs rice cooking. Means. Moreover, since the rice cooking part 1400 is provided in the lower part of the rice washing part 1200, it can cook rice so that the heat | fever and water vapor | steam which generate | occur | produce at the time of rice cooking may not have a bad influence on the rice storage part 1100 (refer FIG. 1). A pressure cooker (not shown) is used.

Next, the operation of the automatic rice cooker of the present embodiment will be described with reference mainly to FIG. 1 (hereinafter, a case where the “new rice mode” is selected by the user will be described).

  The control unit 1500 causes the rice storage unit 1100 to measure a predetermined amount of rice designated by the user. Then, under the control of the control unit 1500, the rice storage unit 1100 measures a predetermined amount of rice with a measuring instrument, and uses the opening 1221 (see FIGS. 2 and 4) to measure the measured amount of rice using the arrow X1 (see FIG. 2). 2), the rice is fed into the rice-washing unit 1200 in a downward direction (note that the amount of rice supplied at one time is recognized in advance by the control unit 1500, and such intermittent rice supply over a plurality of times is controlled by the control unit 2500. Receive).

  On the other hand, the control unit 1500 recognizes that the mode selected by the user among the three modes is the “new rice mode”, and looks at the rice washing table (see FIG. 6) to set the corresponding rice washing condition to “moderate”. The rotation speed and the rotation time of the motor (not shown) of the drive unit 1600 are determined to be “slow” and “short” in order. The drive unit 1600 drives a motor (not shown) according to the rotation speed “slow” and the rotation time “short” determined under the control of the control unit 1500.

  The rice-washing unit 1200 rotates a cylindrical brush 1212 (see FIGS. 2 and 3) attached to the longitudinal rotation shaft 1610 (see FIG. 2) using a driven motor, and moves the predetermined amount of rice fed into the arrow. The rice is washed by rotating the cycle along Y1 to Y3 (see FIG. 2).

  In addition, the rice which was pushed to the lower part of the rice-washing drum 1210 (see FIGS. 2 and 3) by the centrifugal force due to the rotation of the cylindrical brush 1212 (see FIGS. 2 and 3) is lost in the direction of the arrow Y1 against gravity. To the upper part of the rice-washing drum 1210 (see FIGS. 2 and 3) and fall in the directions of the arrows Y2 and Y3 to circulate the above cycle. Further, the rice bran passes through the rice washing plate 1223 (see FIGS. 2 and 4) provided on the inner peripheral surface of the outer peripheral plate 1220 (see FIGS. 2 and 4) and falls out into the closed space 1224 (see FIGS. 2 and 4). Then, it passes through the exhaust tube 1222 (see FIGS. 2 and 4) and is discharged into a tub paper pack (not shown).

  The discharging unit 1300 opens the lower surface of the rice-washing plate 1223 (see FIG. 5) when the vertical rotation shaft 1610 (see FIG. 5) is pushed down, and the rice that has been washed in the rice-cooking unit 1400 provided in the lower portion is indicated by an arrow X2. It is discharged by dropping from the direction of ~ X3 (see FIG. 5). As is clear from the above, the rice is simply dropped freely.

  On the other hand, the control unit 1500 recognizes that the mode selected by the user among the three modes is the “new rice mode”, and looks at the rice cooking table (see FIG. 7). Pre-cooking time, boiling maintenance power, boiling maintenance time, additional cooking time, additional cooking power in order of “less”, “low”, “short”, “large”, “long”, “large”, “long” It determines and performs control to that effect with respect to the rice cooking part 1400. FIG.

  The rice cooking unit 1400 is adjusted according to the control from the control unit 1500 "less", pre-cooking temperature "low", pre-cooking time "short", boiling maintenance power "large", boiling maintenance time "long", The cooked rice is cooked according to the additional cooking power “large” and the additional cooking time “long”. In addition, although the timing which inject | pours water can be considered variously, in order to avoid the uneven distribution of the rice in the pan bottom part which causes uneven cooking, it is better to put water beforehand.
