Abstract: An electric rice oven which can prevent rice from scorching and producing a fluffy, tasty and delicious rice comprising an electrical heater arranged in the lower part of an oven body, exhaust outlets in the upper part of said oven body, and a vent hole 25 adjacent said heater for decreasing residual heat on the inside of the oven body.

Abstract: An apparatus for blending boiled rice and vinegar including a rotatable agitating vessel which is mounted so as to be positioned to face both upwards and sideways. A blower is provided to blow air into the vessel when it is facing sideways to further aid in blending the ingredients.

Abstract: A method of making maki-zushi comprising a preparation process in which a sheet is placed on a sheet frame and said sheet mounts a shari (sushi rice, namely, vinegared rice), gu (ingredients) such as kampyo (dried gourd shavings), cucumber, tuna or the like, and nori (laver), and a maki-zushi (a vinegared rice rolled in laver) materials are disposed with a [play] to roll up the maki-zushi by rolling in the shari, gu, and nori; a rolling in and rolling up process provided with a rolling in and rolling up mechanism in which part of the sheet is rotated in a half turn by utilizing the part of the [play] of the sheet and it is formed into a cylindrical shape for rolling in the shari and is shifted in a direction where the part of the sheet is rolled in and the laver is caused to wrap the shari with the nori to make the maki-zushi; a pressure molding process provided with a pressure molding mechanism in which a pressure mold and a receiving mode are installed on a chain conveyor by providing a so called interval a

Abstract: The wrapping film is composed of an external film and a pair of separating films disposed on an inner surface of the external film, and the pair of the separating films form an accommodating portion for accommodating a laver between the external film and the pair of the separating films by superposing mutual edges thereof in almost the center portion of the external film in free condition, and the laver is accommodated between the external film and the pair of the separating films, and rice is placed on the separating films to be wrapped in with the laver being wrapped in the separated condition from the rice, and a cut line is provided at a position along the superposed edges of the separating films, and when the external film is cut in the center portion and is separated in right and left directions, the rice is spontaneously wrapped in the laver.

Abstract: Rollers each having a plurality of radially extending vanes are arranged in pairs to define a downwardly extending path therebetween which progressively reduces in width from the top to the bottom, so that a material of a foodstuff is compressed while being fed downwardly by the roller pairs through the path. A horizontal conveyor belt lies below the path and is indexed to transfer a predetermined cut length of the material to a shaping station where the material is pushed up into a shaped cavity of a flexible cup member. The flexible cup member is embraced by presser members to shape the material under a preselected adjustable table pressure. The resulting block of material attains hardness and shape which would be provided by hand-shaping.

Abstract: A pair of endless belts define a downwardly extending path therebetween which progressively reduces in width from the top to the bottom, so that a material of a foodstuff is compressed while being fed downwardly by the belts through the path. A horizontal conveyor belt lies below the path and is indexed to transfer a predetermined cut length of the material to a shaping station where the material is pushed up into a shaped cavity of a flexible cup member. The flexible cup member is embraced by presser members to shape the material under a preselected adjustable pressure. The resulting block of material attains hardness and shape which would be provided by hand-shaping. Regardless of the hardness of the material in the downward path between the belts, the material can always be cut by each predetermined amount by adjusting the width of the path and, therefore, the degree of compression of the material.
