Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Applications> The present invention relates to a rice ball manufacturing apparatus that automatically manufactures sandwich-like rice balls in which ingredients are sandwiched between upper and lower layers of cooked rice.

<Conventional technology and its problems> The conventional rice ball manufacturing device manufactures rice balls 9 in which the ingredients are located approximately in the center of the rice ball, and a triangular cavity is formed in a rotating turntable. As the turntable rotates, cooked rice is put into the cavity and pressed, and then the press-formed product is punched and the ingredients are poured into it. Therefore, since the ingredients are located in the center of the rice ball in the rice balls obtained by this manufacturing apparatus, it is necessary to eat only the cooked rice until the ingredients are reached, resulting in a bland rice ball.

An object of the present invention is to solve this problem and provide an apparatus for producing sandwich-like rice balls that allow you to enjoy the ingredients no matter where you eat them.

<[Means for solving the illumination point] In order to achieve the above object, the present invention provides a turntable in which a plurality of cavities of a predetermined shape are formed and rotates intermittently, and a turntable arranged above the rotational track of the turntable and located below. Upstream and downstream hoppers for feeding cooked rice into the cavity, and upstream and downstream press plates for pressing the cooked rice that has descended into the cavity. It is characterized in that a stepped projection for forming a recess for ingredients is formed on the lower surface of the press plate on the upstream side.

Function: The hopper on the upstream side feeds cooked rice, which forms the lower cooked rice layer, into the cavity. The press plate on the upstream side presses the cooked rice to form the lower cooked rice layer into a predetermined shape, and at the same time forms recesses for ingredients in the lower cooked rice layer using its stepped protrusions.

The hopper on the upstream side feeds rice into the cavity to sandwich the ingredients.

The press plate on the downstream side presses this cooked rice to form an upper cooked rice layer, and at the same time binds the upper cooked rice layer and the lower cooked rice layer to form a sandwich-like rice ball with ingredients sandwiched in between.

<Examples> The present invention will be specifically described below with reference to illustrative examples.

The drawings show an embodiment of the present invention; FIG. 1 is a plan view thereof, FIG. 2 is a side view, FIG. 3 is a front view, FIG. 4 is a plan view of the turntable, and FIG. ) to (g) are cross-sectional views showing the manufacturing process. A turntable 11 is mounted on a base 10 that is movable on the body surface. The turntable 11 is connected to the output shaft of a motor (not shown) mounted within the base 10, and is intermittently rotated by the drive of the motor. On the upper surface of this turntable 11, rectangular cavities 1 to 8 are formed at equal intervals on the same circumference. Further, above the turntable 11, hoppers 12 and 13 are provided which are filled with cooked rice. Shoes 1-14 and 15 hanging down above the turntable 11 are connected to each hopper 12 and 13, respectively, with the chute 14 facing above the cavity 1 of the turntable 11, and the chute 15 facing above the cavity 5. There is. Each chute 14.15 is for feeding cooked rice from the hopper 12.13 into the cavity of the turntable 11.
As described later, the cooked rice from chute 14 is the lower cooked rice R3.

becomes. Sliding shutters 16 and 17 are respectively provided at the lower end exits of the chutes 14 and 15, and when the shutters 16 and 17 move out of the exits, rice is introduced, and when the shutters 16 and 17 move toward the exits, the rice input is blocked. It is now possible to do so. In addition, shoot 14.1
As shown in FIG. 3, 5 has a structure in which the cross-sectional area gradually decreases as it goes downward, and is connected to a vibrating arm 18 that provides vibration in the vertical and horizontal directions. In such a structure, the chute 14, 15 vibrates to accelerate the fall of the cooked rice and prevent the cooked rice from bridging each other. Therefore, the cooked rice descends smoothly inside the chutes 14 and 15, but since the cross-sectional area decreases toward the bottom, the density averages out during the descent, allowing it to be fed into the cavity in good condition. It has become. Furthermore, cavity 2
As shown in FIG. 5(b), there is an upstream press plate 19 above the
is provided so as to be movable up and down, and a Cζ downstream press plate 20 is provided above the cavity 6 so as to be movable up and down, as shown in FIG. A stepped projection 19a is formed on the entire central portion of the upstream press plate 19 excluding the peripheral portion, and a recess 33 for ingredients is formed in the lower cooked rice layer 31 by the stepped projection 19a. On the other hand, the downstream press plate 20 has a flat bottom surface, and presses the cooked rice uniformly to form the upper cooked rice layer 32 and integrate the upper and lower cooked rice layers 31 and 32. Note that a receiving plate 22 supported by a cylinder rod 21 is inserted into each of the cavities 1 to 8, so that the cavities 1 to 8 are used with the lower portions closed and the upper portions open. Further, although not shown, an ingredient filler for dropping ingredients is provided above the cavity 4.

In FIGS. 1 and 3, 23 is a conveyor for transporting the formed rice balls 9 to the cutting process.

Next, the operation of the above device will be explained with reference to FIGS. 4 and 5. Before making onigiri, adjust the rice and ingredients. Cooked rice can be prepared in a conventional manner using a rice cooker, etc., and the ingredients can be adjusted in the same way.

Ingredients include umeboshi meat, seasoned bonito flakes,
I-fu, ham, hamburger steak, sausage, wild or boiled vegetables, nozawana, etc. are selected according to the consumer's taste. Also, dry weight of minced meat cutlets, croquettes, tamagoyaki, fried fish and meat.

In addition, ingredients used in sandwiches such as salads can be selected as appropriate, and two or three of these types can also be used in combination. The cooked rice obtained by cooking is cooled to a predetermined temperature and then transferred to hoppers 12 and 13.
is filled with. During operation, the turntable 11
It rotates intermittently in the direction of the arrow in the figure, one-eighth rotation at a time, and its position gradually moves. Therefore, in the following explanation, cavity 1 of the plurality will be explained, but the other cavities 2 to 8 are operated in the same way as cavity 1 at each stop position. When the cavity 1 is located at the position A in Fig. 4, a predetermined amount of cooked rice is filled from the hopper 12 (Fig. 5 (a)).
. Next, when the turntable 11 rotates one-eighth, the cavity 1 moves to the position shown in FIG. 4B. At point B, the upstream press plate 19 descends to press the cooked rice (FIG. 5(b)). This pu.

The lower cooked rice layer 31 is formed into a rectangular shape by the filling process, but
A step-like projection 19a projects downward from the lower surface of the upstream press plate 19, and thereby four parts 33 for ingredients are formed on the inner part of the upper surface of the lower cooked rice H31 excluding the peripheral part. When the turntable 11 further turns one-eighth and the cavity 1 moves to C in FIG. 4, the cylinder is driven and the receiving plate 2 is moved.
2 rises, and the lower cooked rice layer 31 is lifted up to near the upper end of the cavity 1 (FIG. 5(C)), and in this state moves to the fourth diagram. An ingredient filling Wl (not shown) is provided at point D, and the ingredient recess 33 is filled with the ingredient light m.
The ingredients 34 are filled inside. This filling is performed so that the ingredients 34 fill all of the recesses 33, resulting in a two-layered structure in which the ingredients 34 are stacked on the lower cooked rice Ji 131.

In this case, since the lower cooked rice 1131 is lifted up to the upper end of the cavity 1 by the raising of the receiving plate 22, the ingredients 34 can be reliably and easily filled into the recess 33. Thereafter, the cavity 1 moves to the position E in FIG. 4 due to the intermittent rotation of the turntable 11, but prior to this movement, the receiving plate 2
2 is lowered, and a space is formed above the cavity l. A hopper 13 is provided at point E, and a predetermined amount of cooked rice is dropped from the chute 15 into the upper space of the cavity 1 (FIG. 5(e)). Then, the cavity 1 moves to FIG. 4F, and the downstream press plate 20 descends (the fifth
Figure (f)).

As the downstream press plate 20 descends, the additional cooked rice added to the cavity 1 is pressed to form the lower cooked rice layer 32, but at the same time as this forming, the cooked rice around the upper and lower cooked rice layers 31, 32 is bound together. The rice balls 30 are then combined to form a sandwich-like rice ball 30 with ingredients 34 sandwiched in the middle.

Then, when the turntable 11 rotates one-eighth, the cavity 1 reaches the position G in FIG. 4, the receiving plate 22 rises, and the formed rice ball 30 is taken out onto the cavity 1 (
Figure 5(g)). In this state, an arm (not shown) rotates and carries the rice balls 30 onto the conveyor 23, where they are supplied to the next cutting process. With such intermittent rotation of the turntable 11, similar operations are performed in the other cavities 2 to 8 at points A to G, thereby continuously producing rice balls. A cutter (not shown) is provided downstream of the conveyor 23, and the rice balls 30 are divided into two in a diagonal direction.

FIG. 6 is a perspective view of the rice ball 30 obtained by the above method, and since the ingredients 34 sandwiched between the cooked rice J131 and 32 are exposed from the cut surface, the type of the ingredients 34 can be determined. In addition, the toppings 34 are sandwiched over almost the entire surface of the cooked rice layers 31 and 32, creating a highly interesting shape, and the toppings 34 can be eaten from anywhere.
Since you can taste 3, you can make onigiri with deep taste and good palatability. After such molding, the rice ball 33 can be appropriately wrapped in seaweed and then enclosed in a transparent plastic sheet or the like and served.

In this case, it is preferable to wrap the seaweed around the outer surface excluding the cut surface.

In the above embodiment, the cavity 1 is formed into a rectangular shape, but it may be formed into a triangular shape, a hexagonal shape, or any other shape, thereby making it possible to mold a rice ball with a different shape.

<Effects of the Invention> As described above, the present invention improves productivity because rice balls can be manufactured continuously, and also because the manufactured rice balls are in the form of a three-layer sandwich 1. You can enjoy the ingredients no matter where you eat it. It can be used and is effective.
