Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automated Mitsuto type sushi ball forming apparatus for forming a sushi ball having a predetermined shape, size and hardness as a pre-process, for example, when gripping nigiri sushi. .

[0002]

2. Description of the Related Art Nigiri sushi, conventionally called Edo-mae, is used by a sushi chef who puts wasabi and fresh seafood on a sushi ball holding a sushi rice in a bite size, and uses the palms and fingertips of the hand again. And tightened from all sides to form a predetermined shape.

[0003] However, as described above, if the production of nigiri sushi relies on the skills of a sushi chef, the production cost increases. Therefore, in response to recent shortages of craftsmen and demands for lower manufacturing costs, a so-called sushi robot that automatically manufactures sushi balls by a machine has been developed and is currently used in sushi restaurants and restaurants. .

[0004] However, customers still do not want mechanization, and this is a major factor that hinders the further spread of sushi robots.

As a countermeasure, a large number of sushi balls are manufactured using a sushi robot in a place invisible to the customer, and the sushi balls are put into stockers or the like and brought to a sushi shop or the like.

[0006]

However, when using the above-mentioned method, it takes too much time from the production of sushi balls to the making of nigiri sushi, so that not only the taste is lowered but also the quality is deteriorated. There's a problem. Furthermore, there is a problem that it is easily formed into a hard sushi ball due to compression by a machine.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has a built-in sushi ball forming machine inside a casserole-shaped container so that the sushi ball forming machine can be reduced in size and moved. It is easy to transport, can be used in a narrow place, and can be quickly molded out of soft sushi balls at the same time as it can be taken out from the upper take-out part of the container. It is an object of the present invention to provide a sushi ball forming apparatus that can take out a sushi ball with the same operation as that performed by a craftsman.

[0008]

According to the present invention, in order to achieve the above object, according to the present invention, a sushi ball forming machine is built in a mortar-shaped container so that sushi balls can be taken out from the upper part of the container. The sushi ball forming machine, sushi rice,
A sushi rice compression / conveying mechanism that pushes up and compresses from the bottom to the top, a sushi rice that is pushed up and pressed by the compression / conveying mechanism, a compression molding mechanism that compression-molds the sushi rice into a predetermined shape through a molding hole, and a sushi rice that is pushed up from the molding hole. And a cutting mechanism for cutting into a predetermined length to form a sushi ball.

According to a second aspect of the present invention, the compression / conveying mechanism is formed by vertically supporting a screw conveyor that rotates so as to push up sushi rice from a lower portion to an upper portion, and extends above an upper end of a conveyor shaft of the screw conveyor. A space is formed at the lower center of the compression-molded sushi rice.

[0010]

The sushi rice put into the hopper is compressed and transferred from the lower part to the upper part by the screw conveyor of the sushi ball forming machine, and is cut and formed into sushi balls of a predetermined size and shape in the upper part of the container. . At this time, since a space is formed inside the sushi ball, a soft sushi ball is obtained. Since the sushi ball forming machine is built in the Obin type container, if the sushi ball shaped as above is taken out from the upper part of the Obin type container, the sushi chef will take out the sushi rice from the Obisu in appearance It looks like the same operation as above, and it is possible to eliminate the customer's resistance to the mechanization of sushi ball molding.
