A square planar heater 37 is also attached to the innermost side 17a 'of the open / close lid 17a (see FIG. 13A). And the said heat insulating material 38 is similarly affixed on the outer side surface where these planar heaters 37 were affixed (refer FIG. 2, FIG. 3).

  In this manner, the sheet heater 37 is attached to the entire (entire surface) (the hatched portion in FIGS. 11 and 12) of the food material heat retaining casing 19 to form a heat insulating material 38 and a side switch structure. By maintaining the temperature of 80 ° C. to 85 ° C., for example, the inside of the food hopper 12 and the inside of the food conveying unit 2 can be maintained at a substantially uniform temperature (for example, 70 ° C.) at any position. Can be kept warm evenly. As described above, since the interior of the food material heat retaining casing 18 can be maintained at a substantially uniform temperature regardless of the position, dew condensation due to uneven temperature does not occur in the casing as in the prior art.

Since the present invention is configured as described above, its operation will be described below.
First, the heater switch on the operation panel 13 is turned on. Next, the lid 11b of the housing 11 is opened, the cooked rice (rice) is put into the food hopper 12, and the lid 11b is closed. It is assumed that the rice is charged up to the vicinity of the upper edge of the hopper 12 (position X in FIG. 2). At this time, the rice falls from the lower end portion 12 c of the hopper 12 onto the fixed disk 23 below and is placed on the fixed disk 23.

  In this state, when the sheet heater 37 is energized, the temperature inside the food insulation case 19 is maintained at approximately 70 ° C., so that the cooked rice can be kept warm. it can.

  Next, the food container 3 is placed on the container mounting portion 14 and a switch for a predetermined food weight on the operation panel 13 is turned on.

  Then, by driving the drive motors M1 and M2, the food feed blade 20 starts to rotate in the direction of arrow A, and at the same time, the rotating cylinder 8 starts to rotate in the direction opposite to the food feed blade 20 (arrow B direction). . Further, when the driving motors M3 and M4 are driven, the unrolling rollers 1a and 1b start to rotate in the opposite direction, and the shutter 15 is slid by the driving cylinder and opened below the rollers 1a and 1b.

  When the food feed blade 20 rotates in the direction of arrow A, the rice placed on the fixed disk 23 is pushed in the direction of arrow A by the curved surface 20a of the food feed blade 20 and is gradually moved by the curved surface 20a. It is transferred in the direction of the outer peripheral edge of the fixed disk 23, and is dropped and supplied into the food chambers 10 of the rotating cylindrical body 8 on the fixed bottom plate 18a through the annular space S from substantially the entire outer peripheral edge of the fixed disk 23. .

  Since the rotating cylinder 8 rotates in the direction opposite to the food feed blade 20, the food chambers 10 also move (rotate) in the direction of arrow B, and the rice is the outer peripheral edge of the fixed disk 23. Are continuously dropped into the rotating food room 10. Therefore, the rice dropped into the food compartment 10 is conveyed on the fixed bottom plate 18a by the partition plates 9 in the direction opposite to the direction of rotation of the food feed blades 20 (arrow B direction). When crossing over the opening 6, it is successively dropped from the opening 6 between the lower unrolling rollers 1 a and 1 b. Therefore, even if it is a food that tends to form a lump such as cooked rice, it is possible to receive the food falling from the outer peripheral edge of the fixed disk 23 in the food chamber 10 of the rotating cylinder 8 that rotates in the opposite direction. It is possible to receive a substantially fixed amount of food in each food room 10 and transport it to the opening 6.

  In this way, the rice supplied from the food hopper 12 to the food conveying unit 2 is dropped and supplied onto the fixed disk 23 below the hopper 12 and is fed radially from the central axis P on the fixed surface plate 23. The blades 20 are uniformly transferred in a radial direction from the central axis P toward the outer peripheral edge by the blades 20, and continuously from the entire peripheral position of the outer peripheral edge of the fixed bottom board 23 into the lower food chamber 10. Can be supplied to. Therefore, unlike the conventional apparatus, the rice is not transferred to one side in the horizontal direction, so that the rice does not remain at a position opposite to the conveying direction of the rice, and all the rice can be sent out without waste. Further, the rice is transferred radially from the central axis P by the rotating food feed blade 20, and the rice dropped in the food chamber 10 is transferred in the rotating direction by the partition plate 9, so that the transfer distance of the rice is also short. It does not put extra stress on the rice.

  Furthermore, the rice dropped and supplied to the food chamber 10 is transferred in the rotation direction by the partition plate 9 of the rotating cylindrical body 8 and reliably transferred to the opening 6 provided in the fixed bottom plate 18a. The supplied food can also be unwound and supplied to the rollers 1a and 1b without waste. In this way, the food material chamber 10 sequentially arrives at the opening 6, so that rice is sequentially supplied from the opening 6.

  The rice falling downward from the opening 6 is supplied by dropping between the unrolling rollers 1a and 1b (center portion centered on the center line K '). At this time, since the unrolling rollers 1a and 1b rotate in the opposing direction (arrows C and C ′ directions), the dropped rice is supplied to the protrusions 34 and 35 and the cylindrical surface of the unrolling rollers 1a and 1b. In this way, the rice is caught in a plurality of small spaces S1, S2 and S3 formed by the above, and the rice is broken up finely and supplied to the food container 3 below.

  Further, in the rice unwinding operation, the shape of the protrusion 34 of the unrolling roller 1a and the protrusion 35 of the unrolling roller 1b are different, so that the rice is unraveled more effectively in the spaces S1, S2, and S3. Is called. That is, the projection 35 of the other unrolling roller 1b is provided with an annular plate portion 35b on the outer periphery of the cylinder of the roller and the projection 35 is provided on the outer peripheral edge thereof. By being positioned so as to enter between the protrusion rows 34 ′ and 34 ′ of the unrolling roller 1 a, a closed space S 4 (between the opposed annular plates 35 ″ and 35 ″ and the cylindrical outer peripheral surface of the unrolling roller 1 b ( In the above embodiment, the protrusions 34 of the protrusion row 34 ′ of the unrolling roller 1 a sequentially enter into the central portion (three places in the central portion and two places in the front and rear end portions). In S3, the rice is sufficiently unwound.

  When rice is dropped and supplied into the food container 3, the weight of the rice is measured by the measuring device 16, and when it is detected by a detector (not shown) that the predetermined food weight has been reached, Driving of the driving motors M1, M2 and the driving motors M3, M4 is stopped, the rotation of the rotating cylinder 8 and the food feed blade 20 is stopped, and the rotation of the unrolling rollers 1a, 1b is also stopped. The cylinder is driven to contract and the shutter 15 is closed. Thereby, a predetermined amount of rice can be arranged in the food container 3.

  The shape and number of the protrusions 34 and 35 of the unrolling rollers 1a and 1b are not limited to the above embodiment, and various shapes are conceivable. Further, the rotational speeds of the drive motors M1 and M2 are changed, that is, the rotational speeds of the unrolling roller 1a and the unrolling roller 1b are changed independently, or both rollers 1a and 1b are rotated at different speeds. By changing the rotation speed in accordance with the amount of rice to be fed, it is possible to adjust the degree of unwinding of the rice or the amount supplied to the food container 3.

  In this way, each time the switch is pressed, a predetermined amount of rice can be sequentially supplied to the food container 3. During that time, the planar heater 37 is energized, and the position inside the food heat insulation case 19 is determined. In this case, the temperature is maintained at a substantially constant temperature (about 70 ° C.), so that no dew condensation occurs in the casing 19, and warm delicious rice can always be supplied to the food container 3.

  As described above, according to the present invention, the food (rice) supplied onto the fixed disk 23 is transferred in the radial direction toward the outer peripheral edge of the fixed disk 23 by the rotation of the food feed blade 20, and the lower rotating cylinder. Since it is dropped and supplied to the food room 10 of the body 8 and is transferred in the circumferential direction by the partition plate 9 of the food room 10, the food material does not remain in the food material transport unit 2, and extra stress is applied to the food material. It can be smoothly conveyed to the unrolling rollers 1a and 1b without any problems.

  Further, when the food feed blade 20 is rotated, the food material can be smoothly conveyed in the direction of the outer peripheral edge of the fixed disk 23 smoothly by the arc surface 20a.

  Moreover, even if it is a food in which a lump is easy to be formed, such as freshly cooked rice, the food falling from the outer peripheral edge of the fixed disk 23 can be received in the food chamber 10 of the rotating cylinder 8 rotating in the opposite direction. It is possible to receive a substantially fixed amount of food in each food room 10 and transport it to the opening 6.

  Further, since the tip portion 20a of the food feed blade 20 is located in the vicinity of the outer peripheral edge of the fixed disk 23, the food material falling on the fixed disk 23 is not dropped and supplied to the food chamber 10 from the outer peripheral edge of the fixed disk 23. be able to.

  In addition, the food supplied to the hopper 12 can be reliably supplied onto the fixed disk 23.

  2 and 10, 6 ′ is an opening provided in the casing of the internal machine casing 11 a and the rice breaking rollers 1 a and 1 b, and is provided at the same position as the opening 6.

  According to the present invention, since the food can be transported to the unrolling roller without causing the food to remain in the food transport unit and without applying extra stress to the food, the food is served on the bowl. It can be widely used as a food conveying mechanism of the apparatus.
