2. Description of the Related Art A rolled sushi, for example, a rolled sushi roll with seaweed, is made by placing seaweed on a rice cake, and then putting rice cooked on it and rolling it thinly. Depending on the quantity, it is formed into a thick roll or a thin roll, and then cut into appropriate lengths. Therefore, although the seaweed is wound around the side surface, the seaweed is not wound on both end surfaces, and the tools put inside can be seen. Apart from eating with chopsticks, when sushi is rolled in this way, when picking it up by hand, hold the part wrapped with nori so that rice does not get in your hands, Or, sushi is eaten with sauce such as soy sauce on the edge.

[0003]

However, the conventional seaweed maki sushi made in this manner is easily prepared and eaten at home and in sushi restaurants and other restaurants because of its simple method of making. However, since seaweed is wrapped around the entire circumference, a belt-shaped wrapping tool is indispensable in place of a lacquerware in the case of mechanical production, and it is difficult to continuously mechanize it. Also, the conventional nori maki sushi made in this way has both ends exposed, so when eating with chopsticks, rabbits have horns, especially children with small hands have a nori part. However, there was a problem that the cooked rice on the end face of the hand was attached to the hand and the hand was easily stained. An object of the present invention is to solve the problems related to the conventional laver winding.

[0011] In the present invention, the sushi is a rice cooked product,
For example, the cooked rice is formed into a roughly cylindrical or hexahedral or other polyhedral shape, and one end face of the cooked rice product and a side face connected to the end face are coated with laver or kelp. In the case where the cooked rice product is formed into a cylindrical body in a rough shape, one of the opposed end surfaces of the cooked rice molded product formed in the cylindrical body and a pair of side surfaces that are continuous with the end surface and face each other It is manufactured by coating a part of the part with an elongated food film such as laver or kelp. In the present invention, also, an end surface of the cooked rice product formed in a cylindrical shape with a rough shape, which is not covered with the food material film, and a pair of side surfaces which are continuous with the end surface and are not covered with the food material film Can be manufactured by coating another part of the food film of another type or the same type of food film.

In the case where the cooked rice product is formed into a hexahedron or other polyhedral shape in a rough shape, one of two opposing end faces and one of the end faces and the side faces connected to the end face and facing each other are formed. It is manufactured by covering a part of each of a pair of sides with a long and thin food film such as laver or kelp. In any case, the food film adheres to the cooked rice product due to the adhesive force of the cooked rice. In the present invention, the end surface of the rice cooked product formed in a hexahedral shape with a rough shape that is not covered with the food film and a part of a pair of side surfaces that are connected to the end surface and are not covered with the food film. In addition, it can be manufactured by coating with another elongated different type of food film or the same type of food film.

In the present invention, the food film is, for example, a food film for sushi, and is an edible film formed into a film containing, for example, nori, kelp, bonito, wasabi, mentaiko, salmon, or shiso. However, a food film obtained by combining these food films into one food film and other edible films can be used. Therefore, in the present invention, the same or different food film can be coated twice on the same one end face and a set of opposed side faces of the cooked rice product to form a sushi. In this way, various sushi with different flavors can be formed by combining various foodstuff films. The same applies to the case where sushi is formed by covering the entire surface of the cooked rice product.

In the present invention, for example, in a schematic shape,
A part of one set of one of the opposed end faces and one of the side faces connected to the end face of the cooked rice product molded into a cylindrical body or hexahedron or other polyhedron shape is covered with an elongated food film such as laver or kelp. The sushi to be formed is such that the center of an elongated food film is applied to one end face of the cooked rice molded article having a shape having the side faces connected to the opposite end face and the two end faces, and then to the end face of the cooked rice food article. Push both sides of the applied elongated food film toward the corresponding side surface of the cooked rice product, and fold both sides of the food film onto the opposite side surface that is continuous with the end surface of the cooked rice product. By covering over the body, at least a part of each of the end face of the cooked rice molded body and a pair of side faces facing the end face and facing each other is covered with a food film such as laver or kelp. It can be produced.

Further, the sushi of the present invention is also characterized in that, for example, a cooked rice food product which is partially covered with the food material film produced in this way, for example, is formed into a cylindrical or hexahedral or other polyhedral shape. An end surface not covered with the food film and a pair of side surfaces facing each other are formed so that the cooked rice product partially covered with the food film is positioned so as to face the horizontal direction. Rotate about 90 ° to the center so that the end face not covered with the food film and a set of opposing sides are oriented horizontally, and the end face not covered with the food film is elongated. Apply the center of the food film, then push both sides of the elongated food film applied to the end face of the cooked rice product toward the left and right sides of the cooked rice product, and press both sides of the food film to form the cooked rice product. By folding over the side not covered with the food film and coating the cooked rice product, at least a part of each of the both end faces and all side surfaces of the cooked rice product is covered with a food film such as laver or kelp. It can also be manufactured.

In this way, for example, a cylindrical or hexahedral sushi in which the food film is bent and attached to one end face and a set of side faces of the cooked rice product is further provided on the lower side of the conveyor belt. The other side of the sushi is covered with the food film by coating the other side of the sushi with the food film on the end face and the set of side faces which are not covered with the food film by the simple food film supply device and the food film bending and coating device. Can be done.

As described above, the end surface and the side surface of the cooked rice product not covered with the food film are further covered with another food film, and the whole surface of the cooked rice product is covered with the food film, thereby making sushi. In the case of production, it is necessary that the end face of the sushi that is not coated with the food film and a set of opposing side faces face the side to be coated on the conveyor belt surface. Therefore, in the present invention, in order to direct the end face and one set of side faces not covered with the food film of sushi to the direction in which the food film is coated, a molded rice cooked product coated with one food film is used. The sushi is rotated by an angle of about 90 ° about a line connecting the centers of the opposing end faces with the axis as the center of rotation. By this rotation, the sushi of the cooked rice product having the food film coated on one end surface and a pair of opposing side surfaces, the side not coated with the food film, the side to be coated with the food film, that is, in the left and right direction Can turn. Further, in the present invention, two food film bending and covering apparatus,
When provided on the same side, in order to turn the end face not covered with the food film to the side to be coated with the food film, a sushi of a cooked rice product partly covered with the food film, Spin on conveyor belt at an angle of about 180 °. These rotations are performed by a rotating device. In the present invention, the rotation includes rotation in one direction and rotation in the forward and reverse directions, that is, rocking, and the rotating device includes a rotating device and a rocking device.
