Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for automatically manufacturing nigiri sushi in a continuous and consistent working process.

Devices that automatically produce nigiri sushi have not yet been put to practical use, so a fixed amount of cooked rice is supplied to a mold and pressed using conventional nigiri rice manufacturing equipment such as a pressing roller or die. be done.

However, compared to sushi made by hand, the sushi made using the rice ball making apparatus is different from the sushi made by hand in that it crumbles easily and has a poor texture when eaten. The reason why hand-made sushi does not fall apart easily and has an excellent texture is because the rice and sushi ingredients of the sushi are repeatedly squeezed and squeezed together, resulting in a better texture. However, when using conventional rice ball manufacturing equipment, for example, if you increase the pressing force when forming sushi or lengthen the pressing time when forming sushi, in order to prevent the sushi from falling easily. Although the finished sushi will be difficult to fall apart,
The drawback was that it felt hard. However, if you reduce the pressing force when forming sushi or shorten the pressing time when forming sushi, you can avoid the hardness of the sushi, but the finished sushi will be more likely to break down, and the optimal conditions must be met. It was not easy to ask for it, and it was a problem.

The present invention aims to improve the ease of crumbling and poor texture of sushi made using such conventional rice ball manufacturing equipment. The present invention provides an automatic sushi manufacturing device that enables automation by press-molding the sushi after it has been left for a certain period of time.

The present invention provides a rice and rice supply station that is equipped with a constant amount of rice supply device, a wasabi supply and press molding station that is equipped with a wasabi supply device and an upper die press device, and a sushi seed supply that is equipped with a sushi seed supply device. A station, a press molding station provided with an upper die pressing device, and a nigiri sushi take-out station, and a nigiri sushi manufacturing work station provided in this order;
In a nigiri sushi manufacturing apparatus equipped with a lower mold transfer device in which a lower mold transfer path is formed, a stepped portion is provided in the lower mold transfer path below each press molding station, and a push-up plate connected to a reciprocating member is provided on the lower step. The sushi making device is characterized by forming a lower die receiving surface and being arranged so as to be reciprocally movable.

In the present invention, the lower die transfer path and the nigiri sushi manufacturing station may be formed in a straight line, but if they are provided in the form of a turntable, they will be more compact.
This is preferable because it does not take up much space.

A conventional device can be used as the device for feeding a fixed amount of cooked rice provided at the rice feeding station.

The wasabi feeding device and the device for pressing cooked rice installed in the wasabi feeding/press molding station include a pressing device in which a wasabi injection hole is bored in the upper mold for pressing, and a wasabi feeding pipe is connected to the other end of the hole. It is preferable to use this method because it is possible to supply wasabi and press-form the cooked rice.
However, it is also possible to perform wasabi feeding and pressing with the upper mold in separate steps, although at the same station.

In this press molding, a push-up plate is provided at the lower stage of the cam that initially falls in a stepped manner, and the lower die push-up plate moves the cam upward, thereby making it possible to reduce the stroke of movement of the upper die. In addition, by applying not only the pressing force of the upper mold but also the pressing force of the lower mold, it becomes easier to equalize the pressing force applied to the rice, which is excellent in forming sushi. There is.

In order to carry out such cooperative pressing of the upper mold and the lower mold in one station, it is preferable to carry out the pressing from the same drive shaft via a link, since the pressing operation can be easily carried out in synchronization.

The sushi seed supply station can be a conventional sushi seed supply device having a humidifier, a hopper, and an air cylinder.

The press molding mechanism of the wasabi supply and press molding station is applied to the press molding device of the press molding station. In this way, when the shaped rice is left for a certain period of time, the elasticity of the rice makes the shaped rice slightly swollen compared to after it was formed, so by press-molding it again, it has just the right amount of softness. This allows you to make sushi that doesn't fall apart easily.

The station for taking out the extruded sushi rolls is not limited to one location, but can be provided at a plurality of positions.
