In addition, although the case where the two unrolling members 2c and 2d are installed in the cooked rice supply cylinder 2b has been described here, the present invention is not limited to this, and for example, only one member may be provided.

  The fixed blade 2e is in a state in which the fixed blade 2e is separated from the rotating shaft 2da of the unlocking member 2d in the cooked rice supply cylinder 2b so as to be positioned between the adjacent unwinding blades 2db of the unlocking member 2d. A plurality are arranged along the axial direction. Each fixed blade 2e is formed so as to become gradually thinner from the lower end toward the upper end, and is erected so as to be vertical with the lower end fixed to the inner wall surface on the back side in the cooked rice supply cylinder 2b. .

  The above-described cooked rice measuring and dividing unit 3 is a mechanism unit that measures and divides the cooked rice lump conveyed from the cooked rice unraveling unit 2 so as to have a predetermined size, shape, and weight. As shown, a measuring unit 3a and a dividing mechanism unit (dividing means) 3b (see FIGS. 2 and 3) installed at the lowermost portion of the cooked rice lump transport outlet are provided.

  The measuring part 3a is installed in the lower part of the above-mentioned cooked rice supply cylinder 2b. The transfer entrance portion of the cooked rice lump at the upper part of the measuring unit 3a coincides with the lower part of the opening 2ba of the cooked rice supply cylinder 2b and is connected in a communicating state.

  In the measuring unit 3a, a pair of rollers 3aa, 3ab, 3ac arranged in such a manner as to face each other across the conveying space for the cooked rice lump is installed in order along the conveying direction (downward) of the cooked rice lump. Here, a case where a pair of three rollers 3aa, 3ab, 3ac having a large diameter, a medium diameter, and a small diameter is arranged from the top to the bottom is illustrated, but the number of stages of the pair of rollers is as follows. For example, two or four stages may be used.

  Each of the pair of rollers 3aa, 3ab, 3ac is pivotally supported on the inner wall surface on the back side of the measuring portion 3a while being rotatable in the opposite direction (inward) as shown by the arrows in FIG. It arrange | positions so that the opposing space | interval (conveyance space of cooked rice lump) of each pair may become narrow along the conveyance direction of cooked rice lump. Thereby, the cooked rice lump sent to the weighing unit 3a is configured to be sent downward while being sequentially compressed by the pair of rollers 3aa, 3ab, 3ac while the density of the rice grains is kept constant.

  On the outer periphery of the uppermost pair of rollers 3aa, 3aa, a plurality of protrusions Pf for scraping the cooked rice lump downward are formed at predetermined intervals so as to form irregularities along the circumferential direction. Yes. Also, a plurality of protrusions Ps, Pt for scraping the cooked rice lump downward on the outer periphery of each of the middle and lower pair of rollers 3ab, 3ac are determined in advance so as to form irregularities along the circumferential direction. It is formed at intervals. Further, the outer circumferences of the pair of rollers 3ab and 3ac at the middle and lower stages are formed so as to have a substantially elongated arc shape when viewed from above. When the outer circumferences of the pair of rollers 3ab and 3ac are combined, a substantially flat ellipse is formed. A shaped conveyance space is formed.

  The above-described dividing mechanism portion 3b includes a fixed blade 3ba and a movable blade 3bb (see FIG. 2). The fixed blade 3ba and the movable blade 3bb are installed with their blade edges facing each other toward the transfer outlet of the cooked rice lump.

  The fixed blade 3ba is formed of, for example, a thin plate having a substantially rectangular plane, and is fixed to the lower portion of the measuring unit 3a. The movable blade 3bb is formed of, for example, a thin plate having a substantially rectangular shape that is narrower than the fixed blade 3ba, and is movably installed toward the fixed blade 3ba.

  The cooked rice lump sent from the measuring unit 3a is divided by the sliding motion of the movable blade 3bb at a preset size, shape and weight, and is formed in the forming hole of the turntable 4 (see FIGS. 2 and 3). (Not shown).

  Next, FIGS. 4 and 5 are exploded perspective views of the cooked rice forming apparatus, FIG. 6 is an overall perspective view showing the turntable of FIGS. 4 and 5 extracted, and FIG. 7 is the cooked rice forming apparatus of FIGS. FIG. 8 is a perspective view of the molded lower mold of FIG. 7, and FIG. 9 is a perspective view showing the pressing surface (lower surface) of the molded upper mold of FIGS. FIG. 10 and FIG. 10 are sectional views showing the upper mold of FIG. 9 cut along the longitudinal direction. 4 and 5, the cooked rice weighing division 3 shown in FIG. 1 and the like is removed.

  The turntable 4 shown in FIGS. 4 to 6 is formed of, for example, a planar circular plate and can be intermittently rotated counterclockwise by a drive source (not shown) built in the gantry 5. It is pivotally supported on the gantry 5.

  In the vicinity of the outer periphery of the turntable 4, a plurality of forming holes MH are formed that penetrate the upper and lower surfaces of the turntable 4 at predetermined intervals along the outer peripheral direction. The molding hole MH is a hole that accommodates the mass of cooked rice and has a planar shape, for example, a rounded rectangular shape. However, the shape of the forming hole MH is not limited to this, and may be, for example, a rounded triangular shape, a circular shape, or an elliptical shape.

  Further, on the outer periphery of the turntable 4, a molding device (molding unit) 6 that molds the cooked rice cake after measurement division into a product shape (final shape) is installed. As shown in FIG. 7, the molding apparatus 6 includes a molding lower mold 6L and a molding upper mold 6U.

  The molding lower die 6L is accommodated in each molding hole MH of the turntable 4 shown in FIGS. As shown in FIGS. 7 and 8, the upper surface of the molded lower mold 6L is formed flat, for example. Further, on the lower surface side of the molding lower mold 6L, as shown in FIG. 8, the rotating roller 6La is in a rotatable state so that the molding lower mold 6L smoothly moves following the intermittent rotation operation of the turntable 4. It is installed at.

  On the other hand, as shown in FIGS. 4 and 5, the upper molding die 6U is joined to the support column 6P via the support member 6S on the outer periphery of the turntable 4 and upstream of the conveyance outlet of the measuring unit 3a. Supported in a vertically movable state.

  As shown in FIG. 9, the pressing surface (lower surface) of the upper molding die 6U is formed in a curved shape that is recessed toward the center in the longitudinal direction, for example. An air injection port 6Ui is bored at substantially the center in the longitudinal direction and the width direction of the pressing surface of the molding upper die 6U. Here, the air inlet 6Ui is formed in, for example, a planar circular shape, and the number thereof is, for example, one. The air inlet 6Ui is connected to an air tube 7t of an air injection device (air injection means) 7 shown in FIGS.

  At the time of molding, the molding hole MH, in which the mass of cooked rice is accommodated in the turntable 4, is positioned directly below the pressing surface (lower surface) of the molding upper die 6U, and the upper surface of the molding lower die 6L and the molding upper die 6U are pressed. After making the surface (lower surface) face each other, the cooked rice lump is molded by pressing the cooked rice lump in the molding hole MH with the molded upper mold 6U by lowering the molded upper mold 6U.

  The air injection device 7 shown in FIGS. 4 and 5 is a device that injects air into the cooked rice lump after the measurement division, and includes an air supply source 7g and an air tube 7t.

  The air supply source 7g is a device that generates air, and for example, an air compressor is used. The air tube 7t is a member that guides air (compressed air) generated by the air supply source 7g to the air inlet 6Ui (see FIG. 9) of the pressing surface (lower surface) of the upper molding die 6U. The air tube 7t is formed of, for example, flexible rubber so that it can follow the vertical movement of the molding upper die 6U and can withstand the operation. The injection of air (compressed air) into the cooked rice lump is performed, for example, using the start of lowering of the forming upper die 6U as a trigger.

  In the present embodiment, as shown in FIG. 10, in the process of forming the cooked rice mass RM accommodated in the molding hole MH of the turntable 4 by the molding device 6 after the measurement division, the molded upper die 6U descends and the cooked rice mass. Immediately before coming into contact with the RM, the air (compressed air) A sent through the air tube 7t to the air inlet 6Ui on the pressing surface of the upper mold 6U is injected into the cooked rice RM. Note that the air A may be injected once in a single air injection process or may be discontinuous and multiple times.

  Thus, by injecting air into the cooked rice lump RM, air can be included in the cooked rice lump RM while maintaining an appropriate amount of the formed cooked rice lump RM. For this reason, as a final product, the outside is firm, and the inside is soft and the whole can be formed into a cooked rice lump RM such as a sushi-shari ball that can be immediately released when put into the mouth with a moderate hardness. And even after the cooked rice lump has been cooled or refrigerated for storage, the texture can be prevented from being lost.

  Moreover, since the cooked rice lump RM can be expanded by the capacity of the molding hole MH by injecting air into the cooked rice lump RM, the force for pressing the cooked rice lump RM with the molding upper die 6U can be reduced accordingly. For this reason, since the pressure added to the cooked rice lump RM can be reduced, the soft feeling inside the cooked rice lump RM can be maintained.

  Moreover, the injection time of the air A to the cooked rice lump RM is, for example, about 0.2 seconds. For this reason, the cooked rice lump RM is not dried due to the injection of air A. Therefore, the texture of the cooked rice lump RM does not drop just because air is injected.

  Furthermore, since the members are shared by the molding device 6 and the air injection device 7, the cooked rice molding device 1 can be made smaller than when the molding device 6 and the air injection device 7 are provided independently. Moreover, since a member can be reduced, the cost of the cooked rice molding apparatus 1 can be reduced.

  However, the number and shape of the air inlets 6Ui described above are not limited to those described above, and can be variously changed. FIG. 11 is a perspective view showing the pressing surface (lower surface) of another forming upper mold, and FIG. 12 is a cross-sectional view showing the forming upper mold of FIG. 11 cut along the longitudinal direction.

  Here, for example, two air inlets 6Ui are perforated. Each air inlet 6Ui is arranged along the longitudinal direction at the center in the longitudinal direction and the width direction of the pressing surface of the molding upper die 6U. The planar shape of each air inlet 6Ui is formed in a circular shape, for example, and has the same diameter. Since the air injection port 6Ui is arranged in this way, the air injection range can be expanded in the longitudinal direction of the cooked rice lump RM, so that the air is uniform throughout the cooked rice lump according to the shape of the cooked rice lump. Can be injected.

  However, three or more air inlets 6Ui may be arranged. When a plurality of air inlets 6Ui are arranged, the planar shape and size (diameter) of the air inlet 6Ui may be changed for each arranged position. In that case, the air pressure and flow rate may be changed according to the air injection position by changing the planar shape and size of the air injection port 6Ui.

  FIG. 13 is a perspective view showing the pressing surface (lower surface) of another example of the molding upper mold, and FIG. 14 is a cross-sectional view of the molding upper mold of FIG. 13 cut along the longitudinal direction.

  Here, a protrusion 6Up that protrudes in a direction intersecting (for example, orthogonal to) the pressing surface is formed at the center in the longitudinal direction and the width direction of the pressing surface of the molding upper die 6U. An air inlet 6Ui is drilled in the distal end surface.

  If the injection of air into the cooked rice chunk is at an early stage before pressing, air cannot be injected into the cooked rice chunk. Moreover, after molding, it is difficult to uniformly inject air into the whole cooked rice mass. On the other hand, when the molding upper die 6U of FIG. 13 is used, as shown in FIG. 14, the tip of the protrusion 6Up is placed inside the cooked rice RM immediately before the pressing surface of the molding upper die 6U contacts the cooked rice RM. It is possible to inject air into the cooked rice lump RM in a state where it is inserted into the bowl. For this reason, air can be inject | poured so that it may become uniform in the whole cooked rice RM.

  However, in this case as well, a plurality of protrusions 6Up may be provided, and the air inlet 6Ui may be formed in each protrusion 6Up.

  Further, FIG. 15 is a perspective view showing the pressing surface (lower surface) of the molding upper mold of another example.

  Here, the planar shape of the air inlet 6Ui is formed in, for example, a rounded rectangular shape extending along the longitudinal direction of the pressing surface of the upper molding die 6U. The air inlet 6Ui is disposed at the center in the longitudinal direction and the width direction of the pressing surface of the molding upper die 6U. Also in this case, since the air injection range can be expanded in the longitudinal direction of the cooked rice lump RM, air can be injected so as to be uniform throughout the cooked rice lump according to the shape of the cooked rice lump.

  Next, the formation process of the cooked rice lump by the cooked rice molding apparatus 1 of this Embodiment is demonstrated with reference to FIGS.

  First, when cooked rice is put into the cooked rice molding apparatus 1 through the opening 2aa of the hopper 2a of the cooked rice molding apparatus 1, the cooked rice is being unwound by the rotational action of the two-stage unrolling members 2c and 2d in the cooked rice supply cylinder 2b. It falls along the inner wall surface in the supply cylinder 2 b and is sent into the weighing unit 3 a of the cooked rice weighing division unit 3.

  Subsequently, the mass of cooked rice sent into the weighing unit 3a is sent downward while being compressed by the inward rotation of the three pairs of rollers 3aa, 3ab, 3ac, and has a preset size, shape and It is divided by the sliding motion of the movable blade 3bb at the timing of the weight and is accommodated in the forming hole MH of the turntable 4.

  Subsequently, the cooked rice lump in the molding hole MH is sent directly under the upper molding die 6U of the molding apparatus 6 by intermittent rotation of the turntable 4 in the counterclockwise direction. Then, when the upper mold 6U is lowered, the cooked rice lump in the molding hole MH is pressed by the upper mold 6U and formed into a final shape.

  In this molding process, the switch of the air injection device 7 is turned on by the start of the lowering of the molding upper die 6U, and the pressing of the molding upper die 6U immediately before the pressing surface of the molding upper die 6U comes into contact with the cooked rice lump in the molding hole MH. Air (compressed air) is injected into the cooked rice lump from the air inlet 6Ui on the surface.

  As a result, air can be moderately contained in the formed cooked rice lump, so that as the final molded product, the outside is firm, and the inside is soft and the whole is soft enough to be released as soon as it is put into the mouth. Rice lumps such as sushi shari balls can be formed. And even after the cooked rice lump has been cooled or refrigerated for storage, the texture can be prevented from being lost.

Since the other configuration is the same as that of the first embodiment, the description thereof is omitted.

  By providing such a partition plate 15A, the cooked rice lump conveyed in the measuring unit 3a can be formed in a hollow shape, so that the cooked rice lump is maintained while maintaining an appropriate amount of the formed cooked rice lump. Air can be contained inside. In particular, in the present embodiment, the state of the rice grains inside the cooked rice lump after the measurement division is coarser than the state of the external rice grains, so the air injection device 7 injects air into the cooked rice lump. It can be made easier. For this reason, air can be inject | poured so that it may become uniform in the whole cooked rice lump. Therefore, as the final molded product, the outside is firm, and the inside is soft and the whole can be formed into a mass of cooked rice such as a sushi shabu ball that can be immediately released when put in the mouth with a moderate hardness. And even after the cooked rice lump has been cooled or refrigerated for storage, the texture can be prevented from being lost.

  The partition plate 15A is formed of, for example, a fluorine-based resin. As shown in FIGS. 3 to 5, the first partition portion 15Af extending substantially linearly in the vertical direction and the upper portion of the first portion 15Af are formed. It has 2nd part 15As and 3rd part 15At extended in two directions spaced apart from each other.

  Further, as shown in FIGS. 16 and 18 to 20, in the middle partition plate 15 </ b> A, between the first portion 15 </ b> Af and the third portion 15 </ b> At, an oblique direction toward the center in the width direction of the middle partition plate 15 </ b> A. A recess DT extending in the direction is formed. This hollow part DT is hollowed so as not to block the detection light of the sensor that detects the mass of cooked rice.

  Further, as shown in FIGS. 16, 19, and 20, a plurality of rice balls extending in the thickness direction of the partition plate 15A extend along the direction of transporting the cooked rice mass (longitudinal direction of the partition plate 15A). The groove GV is formed with a predetermined interval and width along the width direction of the partition plate 15A.

  Since the groove GV is formed, the contact area between the partition plate 15A and the cooked rice lump can be reduced, and the cooked rice lump can be guided downward along the groove GV. The cooked rice lump can be moved smoothly inside.

  The cross-sectional shape between the groove GV and the adjacent groove GV may be a rectangular wave shape, or may be a sawtooth wave shape. Thereby, since the contact area of the partition plate 15A and the cooked rice chunk can be further reduced, the cooked rice chunk can be moved more smoothly in the measuring unit 3a.

  Further, the width of the groove GV may be smaller than the width of rice. Thereby, rice can also be prevented from entering the groove GV. Furthermore, you may shift in the width direction so that the position of the groove | channel GV of both surfaces which cross | intersects the thickness direction of 15 A of partition plates may not correspond. Thereby, the mechanical strength of the partition plate 15A can be improved.

  Furthermore, instead of the groove GV, a plurality of protrusions may be provided on the surface of the partition plate 15A to form irregularities. The planar shape of the protrusion is, for example, a circular shape, an elliptical shape, a rectangular shape, a triangular shape, or a combination thereof. Further, the protrusion is formed by, for example, embossing.

  By providing a plurality of protrusions (unevenness) on the surface of the partition plate 15A in this way, the contact area between the partition plate 15A and the cooked rice lump can be reduced, so that the cooked rice lump is smoothly moved downward. be able to. Moreover, it is preferable to arrange the plurality of protrusions (unevenness) on the surface of the partition plate 15A so as to guide the cooked rice lump downward. Thereby, a cooked rice lump can be moved further smoothly below.

  As shown in FIGS. 16 to 18, such a partition plate 15 </ b> A has a rice-rice forming apparatus in a state where both surfaces intersecting the thickness direction are set up along the side surfaces of the rice-supply cylinder 2 b and the measuring unit 3 a. It is installed in the conveyance space of 1 cooked rice lump.

  Here, the partition plate 15A has a pair of rollers 3aa, 3ab of the weighing unit 3a from within the cooked rice supply tube 2b so that the width direction of the conveying space of the cooked rice lump of the cooked rice supply tube 2b and the weighing unit 3a is divided into two. It passes through between 3ac facing (conveying space) and extends to the facing (conveying path) between the pair of rollers 3ac at the bottom of the measuring unit 3a and is terminated in the rice lump conveying space.

  As shown in FIG. 17, the first portion 15Af of the intermediate partition plate 15A divides the space between the pair of rollers 3aa, 3ab, 3ac (conveying space) into left and right parts, and in the thickness direction of the intermediate partition plate 15A. It arrange | positions in the center between each pair of roller 3aa, 3ab, 3ac so that the conveyance space of a rice lump may be formed in both sides.

  Further, as shown in FIG. 18, the first portion 15Af of the intermediate partition plate 15A is a pair of rice so that a conveying space for the rice mass is formed on both sides in the width direction of the first portion 15Af of the intermediate partition plate 15A. The rollers 3aa, 3ab, 3ac are arranged at the center in the thickness direction.

  The tip of the second portion 15As of the middle partition plate 15A is fitted into a hole in the inner wall surface on the near side of the cooked rice supply cylinder 2b. On the other hand, the third portion 15At of the partition plate 15A is fixed so as to be caught on the inner wall surface on the back side of the cooked rice supply cylinder 2b. In this way, by fixing the partition plate 15A at the two locations of the upper second portion 15As and the third portion 15At, the first portion 15Af of the partition plate 15A is floated in a hollow state. It can be fixed stably.

  Further, the upper part (second portion 15As and third portion 15At) of the partition plate 15A is disposed between adjacent unraveling blades 2db so as not to contact the unraveling blades 2db on the outer periphery of the unraveling member 2d. In this state, it is arranged in the cooked rice supply cylinder 2b above the measuring unit 3a.

  The reason why the upper part of the partition plate 15A is arranged in the cooked rice supply cylinder 2b above the weighing unit 3a is the first time that the inventors have made experiments by changing the shape and installation position of the partition plate 15A. It is a structure for solving a found problem. The reason will be described below.

  21 is an exploded perspective view of the measuring unit 3a on which the experimental partition plate 50A is mounted, FIG. 22 is an overall perspective view of the experimental partition plate 50A of FIG. 21, and FIG. 23 (a) is the partition of FIG. FIG. 23B is a cross-sectional view of the cooked rice forming apparatus 51 of FIG.

  The middle partition plate 50A is formed, for example, in a plane T shape, and the upper part is the upper part of the inner wall surface on the near side and the far side of the weighing unit 3a (below the boundary between the cooked rice supply cylinder 2b and the weighing unit 3a). Connected and fixed at. As shown in FIGS. 23 (a) and 23 (b), when the upper part of the partition plate 50A is located below the cooked rice supply cylinder 2b, as shown in FIG. 23 (b), the partition plate 50A. The cooked rice mass RM was piled on the upper part of the rice cake, and the cooked rice cake RM could not be fed into the measuring part 3a and could not be weighed.

  FIG. 24 is an exploded perspective view of the measuring unit 3a on which another experimental partition plate 50B is mounted, and FIG. 25 is an overall perspective view of the experimental partition plate 50B in FIG.

  The middle partition plate 50B is formed, for example, in a Y shape in plan view, and the portions extending in two directions from the upper portion thereof are the upper part of the inner wall surface on the near side and the rear side of the weighing unit 3a (measuring with the rice supply cylinder 2b). It is connected and fixed (below the boundary with the part 3a). In this case, the cooked rice chunk that was compressed to some extent was caught on the Y-shaped part of the partition plate 50B, and the cooked rice chunk could not be sent downward.

  FIG. 26 is a perspective view of the measuring unit 3a on which another partition plate 50C to be tested is mounted, and FIG. 27 is a front view of the measuring unit 3a of FIG.

  Here, the case where the fixing position of the middle partition plate 50C was changed by 90 degrees with respect to the middle partition plates 50A and 50B shown in FIGS. 23 and 24 was evaluated. A slit SL is formed at the center in the thickness direction of the uppermost pair of rollers 3aa, 3aa, and the bridge portion 50Ca is placed over the slit SL of the pair of rollers 3aa, 3aa so that the pair of rollers 3aa, 3aa are opposed to each other. An intermediate partition plate 50C was disposed in the middle.

  In this case, the cooked rice lump was piled on the bridge portion 50Ca of the intermediate partition plate 50C (the portion surrounded by the broken line in FIG. 27), and the cooked rice lump could not be sent downward. Moreover, even when the partition plate 50C itself was removed, the state did not change.

  On the other hand, Fig.28 (a) has shown the longitudinal cross-sectional view of the cooked rice forming apparatus 1 of this Embodiment, and the same figure (b) has shown the cross-sectional view of the same figure (a).

  In the case of the present embodiment, as shown in FIGS. 28A and 28B, by positioning the upper part of the partition plate 15A in the cooked rice supply cylinder 2b, as shown in FIG. Since the cooked rice lump RM did not accumulate on the upper part of the partition plate 15A, the cooked rice lump RM could be smoothly moved into the measuring portion 3a without clogging.

  Moreover, according to examination of inventors, it turned out that it is difficult to divide | segment and send a cooked rice lump while the compression force is applied to the cooked rice lump in the measurement part 3a. On the other hand, according to the present embodiment, by arranging the upper part of the partition plate 15A in the cooked rice supply cylinder 2b, the dropped cooked rice lump can be divided at the stage of unraveling the cooked rice lump. Therefore, the cooked rice lump can be satisfactorily formed into a hollow shape in the measuring portion 3a.

  Next, the formation process of the cooked rice lump by the cooked rice molding apparatus 1 of this Embodiment is demonstrated with reference to FIGS.

  First, when cooked rice is put into the cooked rice molding apparatus 1 through the opening 2aa of the hopper 2a of the cooked rice molding apparatus 1, the cooked rice is being unwound by the rotational action of the two-stage unrolling members 2c and 2d in the cooked rice supply cylinder 2b. It is sent to the lower part along the inner wall surface in the supply cylinder 2b.

  Subsequently, the cooked rice lump sent to the lower part in the cooked rice supply cylinder 2b falls in a state of being divided by the partition plate 15A at the stage of unraveling in the cooked rice supply cylinder 2b, and is measured by the cooked rice weighing division unit 3 Sent to the part 3a.

  Subsequently, the cooked rice lump sent into the measuring unit 3a is sent downward while being compressed by the inward rotation of the three pairs of rollers 3aa, 3ab, 3ac. At this time, the cooked rice lump is formed in a hollow shape by the partition plate 15A. Thereby, air can be included in the cooked rice chunk while maintaining an appropriate amount value of the cooked cooked rice chunk.

  Thereafter, the cooked rice lump formed in a hollow shape in the measuring unit 3a is divided by a sliding operation of the movable blade 3bb at a preset size, shape and weight, and is formed in a forming hole (not shown) of the turntable 4. ) Is dropped in. The cooked rice lump inserted into the molding hole of the turntable 4 is pressed from above and below by the molding upper die 6U and the molding lower die 6L (see FIGS. 4, 5 and 7), and cooked rice such as sushi-shari balls. It is formed into a lump.

  In the present embodiment, in the molding step, as in the first embodiment, the pressing surface of the molding upper die 6U immediately before the pressing surface of the molding upper die 6U contacts the cooked rice lump in the molding hole MH. Air is injected into the cooked rice lump from the air inlet 6Ui.

  At this time, the cooked rice lump formed in the hollow shape in the measuring unit 3a has a coarser state of the rice grains inside than the state of the outside rice grains. Injection can be facilitated. For this reason, air can be inject | poured so that it may become uniform in the whole cooked rice lump. Therefore, air can be uniformly and moderately contained in the entire cooked rice lump, so that the final molded product is solid on the outside, and the inside is soft and soft as a whole. Rice lumps such as sushi shari balls can be formed. And even after the cooked rice lump has been cooled or refrigerated for storage, the texture can be prevented from being lost.

  (Third embodiment)

  FIG. 29 is an overall perspective view of a partition plate 15B, which is another example of a member for forming a cooked rice lump conveyed in the cooked rice forming apparatus of the present embodiment in a hollow shape.

  In the same way as the partition plate 15A of the first embodiment, the partition plate 15B used in the present embodiment has a first portion 15Bf extending linearly in the vertical direction and two directions separated from each other from the upper portion. And a third portion 15Bt.

  In this partition plate 15B, the lower portion of the third portion 15Bt is partially removed so that the hollow portion DT of the partition plate 15A of FIG. 20 is widened, and resistance to movement of the cooked rice lump is reduced. In this way, the inclination angle of the inclined portion SP of the first portion 15Bf is formed to be small. The arrangement of the partition plates 15B in the cooked rice forming apparatus 1 is the same as the layout of the partition plates 15A shown in FIGS. In addition, it may replace with the groove | channel GV and may provide the above-mentioned several protrusion (unevenness | corrugation) on the surface of the partition plate 15B.

  When such a partition plate 15B is used, the same effect as in the first embodiment can be obtained, and the contact area with the cooked rice lump can be further reduced, so that the cooked rice lump can be moved more smoothly. I was able to.

  (Fourth embodiment)

  30 is an exploded perspective view of the weighing unit of the cooked rice forming apparatus of the present embodiment, FIG. 31 is an exploded perspective view of the weighing unit of FIG. 30 viewed from the side, and FIG. 32 is the uppermost stage of the weighing unit of FIG. It is a disassembled perspective view of a roller.

  In the present embodiment, as shown in FIGS. 30 and 31, the upper part of the partition plate 15C is connected to the upper part of the inner wall surface on the back side of the measuring part 3a. However, the upper part of the partition plate 15C may be connected to the upper part of the inner wall surface on the near side of the measuring part 3a.

  As shown in FIGS. 30 and 31, the middle partition plate 15C is inclined so as to gradually move away from the inner wall surface on the back side along the conveying direction of the cooked rice lump (downward in FIG. 31) from the upper connection position. A first portion 15Cf extending up to the upper portion of the roller 3ab, and bent downward so as to cross the first portion 15Cf continuously from the first portion 15Cf and extend along the inner wall surface on the far side. And a second portion 15Cs extending to the lower part of the lower roller 3ac. The second portion 15Cs of the middle partition plate 15C is located around the center in the thickness direction of the middle and lowermost rollers 3ab and 3ac.

  By attaching such a partition plate 15C, it was possible to dramatically improve the movement of the cooked rice lump into the measuring unit 3a as compared with the case described with reference to FIGS. Note that a groove GV and a plurality of protrusions (unevenness) may be provided on the surface of the partition plate 15C in the same manner as described in the first and second embodiments.

  In the present embodiment, as shown in FIGS. 30 to 32, a star-shaped flange portion SF is installed at the center in the thickness direction of the uppermost roller 3aa. For this reason, on the outer periphery of the roller 3aa, in addition to the plurality of projections Pf, a star-shaped flange portion SF that is different in shape from the projection Pf and is higher than the projection Pf at the center in the thickness direction of the roller 3aa. The plurality of projecting portions SFP are projected. A plurality of protrusions Pf and SFP are provided so as to form irregularities along the outer periphery of each of the pair of rollers 3aa. However, the star-shaped flange portion SF may be provided in the middle rollers 3ab and 3ab and the lower rollers 3ac and 3ac.

  By providing such a star-shaped flange portion SF, when the mass of cooked rice is likely to be clogged at the uppermost pair of rollers 3aa, 3aa, the force to feed the cooked rice mass by the star-shaped flange portion SF is increased. Therefore, the cooked rice lump can be sent well into the measuring unit 3a.

  The uppermost roller 3aa is a disassembly type, and the star-shaped flange portion SF can be attached and detached. Thereby, according to the shaping | molding process of a cooked rice lump, the flange part SF can be attached or removed. In addition, since the roller 3aa and the star-shaped flange portion SF can be easily cleaned, the roller 3aa can always be kept clean.

  FIG. 33 is an overall perspective view of the cooked rice lump formed using the cooked rice forming apparatus 1 of FIG. When the middle partition plate 15C was attached as described above, the rice density RMG of the final molded product was lower than the front portion RB in the portion RA on the back side, which was below the middle partition plate 15C. In FIG. 33, air is not injected into the cooked rice lump by the air injection device 7.

  (Fifth embodiment)

  In the present embodiment, as shown in FIG. 34 and FIG. 35, the upper part of the partition plate 15D is the lower part of the uppermost pair of rollers 3aa, 3aa of the measuring part 3a (the rice cracker 2 and the cooked rice division). It is detachably connected to the inner wall surface on the back side at a position (below the boundary with the portion 3).

  As shown in FIG. 35, the middle partition plate 15D is inclined so as to gradually move away from the inner wall surface on the back side along the conveying direction of the cooked rice lump (downward in FIG. 35) from the upper connection position. A first portion 15Df extending to the upper part of 3ac and a lowermost step so as to follow the inner wall surface on the back side by bending downward so as to intersect the first portion 15Df continuously from the first portion 15Df. And a second portion 15Ds extending to the center of the roller 3ac.

  Even when such a partition plate 15D was attached, the cooked rice lump in the measuring portion 3a could be formed in a hollow shape. Moreover, the cooked rice lump could be sent well into the measuring unit 3a. Note that a groove GV and a plurality of protrusions (unevenness) may be provided on the surface of the partition plate 15D in the same manner as described in the first and second embodiments.

  FIG. 36 is a perspective view of the measuring unit showing another example of the partition plate 15D. In FIG. 36, the lower part of the second part 15Ds of the partition plate 15D extends to the lower part of the lowermost roller 3ac, and the length of the second part 15Ds is longer than that in FIG.

  According to the study by the present inventors, it has been found that changing the length of the partition plate 15D can change the degree of the hollow state of the cooked rice lump in the measuring portion 3a. For example, when the partition plate 15D is lengthened, the hollow portion of the cooked rice lump is formed in a clear state, and when the partition plate 15D is shortened, the hollow portion of the cooked rice lump is formed in an unclear state.

  Therefore, in the present embodiment, the partition plate 15D is provided in a detachable state so that the type (length) of the partition plate 15D can be changed. The type (length) of the partition plate 15D is changed according to the final molded product. Thereby, the hardness etc. of the cooked rice lump of the final molded product can be changed.
