In the conventional manufacturing method using skewers, rice cakes stick to the skewers after baking the kiritanpo. In particular, the rice cake sticks hard to the part of the skewer to which the kiritanpo is not attached. Therefore, in order to reuse the skewers, it is necessary to soak the skewers in water for a long time and then wash them, which requires stock of the skewers. It is conceivable to soak the skewers with water or coat them with fluorine so that the cooked grains do not stick to the skewers, but in this case, it becomes difficult to wrap the cooked grains around the skewers.

When you bake a kiritanpo stuck on a skewer, the water inside evaporates and tries to get out of the kiritanpo, but when the surface is baked, the water inside is the part of the skewer to which the kiritanpo is not attached (kiritanpo) It is released to the outside only from the end of the Kiritanpo on the side of the skewer that extends to the outside of the. As a result, the internal pressure increases, the kiritanpo swells greatly, and the wall thickness of the kiritanpo becomes thin. When the thickness of the kiritanpo becomes thin, the kiritanpo tends to crumble when it is boiled in a pot.

In view of such problems, it is an object of the present invention to provide a kiritanpo manufacturing apparatus capable of efficiently manufacturing thick kiritanpo.

In order to solve the above problems, the present invention has a tubular portion and
A screw that conveys cooked rice while kneading it in the tubular part,
An outer cylinder fixed to the end of the tubular portion on the side where the cooked rice is transported with the central axis in common with the tubular portion.
A cylindrical mandrel extending from the inside of the outer cylinder to the outside of the outer cylinder on the opposite side of the screw, substantially parallel to the central axis of the tubular portion.
A cylindrical inner diameter adjusting die fitted to the mandrel inside the outer cylinder,
It has an annular outer diameter die fitted inside the end of the outer cylinder on the side opposite to the tubular portion in the direction of the central axis of the tubular portion.
The mandrel provides a kiritanpo manufacturing apparatus in which the length from the outer diameter die to the tip opposite to the screw is longer than the length of the kiritanpo to be manufactured.

According to the present invention, it is possible to provide a kiritanpo manufacturing apparatus capable of efficiently manufacturing a thick kiritanpo.

The tip R forming claw 33 has a recess on the mandrel 13 side in the central axis direction to form a hemispherical internal space convex toward the tip R forming chuck 32 side.

FIG. 4 is a partially enlarged cross-sectional view of the Kiritanpo manufacturing apparatus 100 according to the embodiment of the present application. The area around the mandrel 13 is enlarged and shown. FIG. 4A shows a state before cutting out the cooked rice 50. FIG. 4B shows a state when the cooked rice 50 is cut out and the tip is molded. Hereinafter, a method of manufacturing Kiritanpo by the Kiritanpo manufacturing apparatus 100 and control of the Kiritanpo manufacturing apparatus 100 will be described with reference to FIGS. 1 to 4.

When cooked rice is put in from the cooked rice hopper 10 and the start switch (not shown) of the Kiritanpo manufacturing apparatus 100 is turned on, the screw 9 is rotated about the central axis by the drive of the drive motor 8 shown in FIG. The screw 9 conveys the cooked rice to the mandrel 13 side in the direction of the central axis while kneading the cooked rice.

The cooked rice is squeezed by the outer diameter die 15 and the inner diameter adjusting die 14, and is pushed out of the outer cylinder 11. The cooked rice is continuously extruded by the subsequent cooked rice, guided by the mandrel 13, and while moving toward the tip side of the mandrel 13, is formed into a cylindrical shape centered on the mandrel 13. Since the surface of the mandrel 13 is coated with fluorine and has low frictional resistance, the cylindrical cooked rice can move smoothly. Further, the frictional resistance can be lowered by adjusting the temperature of the mandrel 13 by the rod-shaped heater with a thermocouple built in the mandrel 13.

When the tip of the cylindrical cooked rice reaches the bottom of the cooked rice arrival detection sensor 18, an electric signal is sent from the cooked rice arrival detection sensor 18 to the drive motor 8 and the drive motor 8 is stopped. At about the same time, an electric signal is sent from the cooked rice arrival detection sensor 18 to the Kiritanpo chuck cylinder 21 shown in FIG. 2, and the pair of Kiritanpo cutting claws 22 and 23 rotate so as to sandwich the mandrel 13. After that, the Kiritanpo cutting cylinder 24 shown in FIG. 3 moves the Kiritanpo chuck cylinder 21 toward the tip R forming machine 30 in the direction of the central axis to obtain the cylindrical cooked rice 50 shown in FIG. 4A. Cut out as shown in (b).

In the tip R molding machine 30, the tip R molding claw 33 is opposed to the tip of the cooked rice 50 by the molding front-rear cylinder 31. When the cooked rice 50 is cut out as shown in FIG. 4B, the concave portion of the tip R forming claw 33 is pressed against the tip of the cooked rice 50 by the tip R forming chuck 32. At this time, the pair of Kiritanpo cutting claws 22 and 23 that have been cut out maintain the position when the cooked rice 50 is cut out, so that the cooked rice 50 is pushed by the tip R forming claw 33 and is on the screw 9 side in the direction of the central axis. Prevent moving to. As a result, the end portion of the cooked rice 50 to which the tip R forming claw 33 is pressed is formed into a hemispherical shape, and the kiritanpo is completed.

According to the Kiritanpo manufacturing apparatus 100 described above, a thick Kiritanpo can be efficiently manufactured. Specifically, since the mandrel 13 extends from the outer cylinder 11 longer than the length of the kiritanpo to be manufactured, it is possible to easily cut out and mold the tip of the mandrel 13 in a state where cooked rice is wrapped around the mandrel 13. In addition, there is no need to use skewers, and there is no need to transport, prepare, or wash skewers, which is space efficient and leads to energy savings.

Further, since the kiritanpo manufactured by the above-mentioned kiritanpo manufacturing apparatus 100 has holes from the beginning, when the kiritanpo is baked, there are no problems in manufacturing such as expansion, cracking, and local bumps, so that the thick kiritanpo is thick. Can be done. In addition, the thermal power management when baking Kiritanpo is not as severe as before.

In addition, general Kiritanpo is a method of rolling while pressing it against a fixed plate as a method to make the outer circumference smooth, and since it is molded into a cylindrical shape while stretching rice, the internal stress is small and it is for tight Kiritanpo. It doesn't become. On the other hand, the Kiritanpo manufacturing apparatus 100 uses a screw 9 capable of generating a large pressure difference between the input side and the outlet side of cooked rice, so that the pressure of cooked rice at the time of discharge is several times higher than that of general Kiritanpo. And can increase the density inside the Kiritanpo. As a result, it becomes a kiritanpo that does not easily collapse.

In addition, the Kiritanpo manufacturing apparatus 100 can freely set the outer diameter of the Kiritanpo by changing the outer diameter die 15. Further, the inner diameter of the Kiritanpo can be freely set by adjusting the position of the inner diameter adjusting die 14 in the direction of the central axis. Further, by adjusting the position of the cooked rice arrival detection sensor 18, the length of the kiritanpo can be freely set.

The invention of the present application is not limited to the above embodiment, and various changes and improvements can be made. For example, the cooked rice arrival detection sensor 18, the cutting chuck 20, and the tip R forming machine 30 may not be provided. In this case, for example, the user may visually check the length of the cooked rice squeezed from the outer cylinder 11 and manually cut out the cooked rice to form the tip. Further, the mandrel 13 does not have to have a built-in rod-shaped heater with an electric connector.
