Description

  The present invention relates to a food forming rolling roller and a food forming apparatus.

  There is known a food forming apparatus which takes up a plate-like food and forms it into a cylindrical food such as, for example, a seaweed roll sushi. In a food forming apparatus for forming a seaweed rolled sushi, the rice is formed into a plate in order to form the rice into a cylindrical shape.

  Generally, in a food forming apparatus, a food is rolled by a pair of rolling rollers provided so as to face each other to form the food in a plate shape.

  In addition, the technique regarding the food-forming apparatus which manufactures appropriately the appropriate amount of rolled sushi which was rolled by human hand is disclosed (for example, refer patent document 1).

JP 2007-104922 A

  In the conventional food forming apparatus, since a force (grip force) for scraping the rolled food is necessary, the groove is formed along the axial direction (longitudinal direction) or circumferential direction (short direction) of the side surface of the rolling roller. It was provided.

  However, in the conventional food forming apparatus in which the groove is provided along the axial direction or the circumferential direction of the side surface of the rolling roller, the surface of the food is crushed by the force when the rolling roller rolls, and the texture is improved. It led to badness. Further, in the conventional food forming apparatus, when the food is rolled thinly, the groove is formed in the food by the groove of the rolling roller. In addition, in the conventional food forming apparatus, the thickness of the plate-shaped food is uniform, so that the texture after being rolled up in a cylindrical shape becomes hard. Furthermore, in the conventional food forming apparatus, for example, when the plate-shaped food is cooked rice, the thickness of the cooked rice becomes uniform, so when the ingredients are wrapped in the cooked rice and formed into a seaweed rolled sushi, Ingredients wrapped in cooked rice are easily removed.

  In order to solve the problems in the conventional food forming rolling roller as described above, for example, it is conceivable to provide the shape of the protrusion provided on the side surface of the rolling roller in a discontinuous block shape instead of a groove shape.

  However, in the case of a rolling roller provided with block-like protrusions on the side, a part of the rice grains of rolled rice tends to adhere to the protrusions, and the rice is caught on the rolling roller and rolled up with the rolling roller There's a problem.

  An object of the present invention is to provide a food forming rolling roller capable of improving the forming state of a food.

  The present invention is a food forming rolling roller which rolls to rotate a food, and has a space between a side on which the food is rolled and another protrusion adjacent in the circumferential direction or spiral direction of the side. It is a substantially columnar body having a plurality of projecting portions, and the projecting portions are provided forward of the rolling roller in the direction of rotation of the rolling roller and inclined toward the side surface. And an inclined portion.

Configuration of Food Forming Apparatus As shown in FIG. 1 and FIG. 2, the food forming apparatus 1 according to the embodiment of the present invention accommodates cooked rice (hereinafter referred to as "cooked rice") containing vinegar which is an example of a food material. And a stirring unit 3 for stirring the cooked rice dropped from the hopper 2. The food forming apparatus 1 further includes a rolling unit 4 that rolls the stirred rice into a plate, and a transport unit 5 on which the rolled rice is placed. In the following description, the side on which the hopper 2 of the food forming apparatus 1 is provided is referred to as the upper side, and the side on which the conveying unit 5 is provided is referred to as the lower side. Further, in the following description, the left side in the drawing of FIG. 2 is referred to as the front side of the food forming apparatus 1 and the right side is referred to as the rear side.

  As shown in FIG. 2, the stirring unit 3 includes a first stirring blade 31 and a second stirring blade 32. Each of the first stirring blades 31 and the second stirring blades 32 has four plate-shaped blades whose longitudinal direction is the width direction of the food forming apparatus 1, that is, the direction in which the sheet passes through the sheet of FIG. The 1st stirring blade 31 and the 2nd stirring blade 32 rotate centering around the rotating shaft which the width direction becomes an axial direction. The first stirring blade 31 stirs the boiled rice in the hopper 2 below the bottom of the hopper 2. The second stirring blade 32 is provided obliquely below the first stirring blade 31. After being agitated by the first agitation blade 31, the second stirring blade 32 further stirs the cooked rice which falls obliquely downward by gravity. The second stirring blade 32 outputs the stirred rice to the rolling unit 4 from the output port 33. The cooked rice output from the output port 33 is guided to the rolling unit 4 by the inclined guide 34.

  The rolling unit 4 includes four rollers of a front lower first rolling roller 41, a rear lower second rolling roller 42, a front upper third rolling roller 43, and a rear upper fourth rolling roller 44. There is. The first rolling roller 41 is an embodiment of the food forming rolling roller according to the present invention. The lower first rolling roller 41 and the second rolling roller 42 are rotationally driven as a pair. The upper third rolling roller 43 and the fourth rolling roller 44 are rotationally driven as a pair.

  The 1st rolling roller 41, the 2nd rolling roller 42, the 3rd rolling roller 43, and the 4th rolling roller 44 are formed with resin with the favorable removability of rice. The outer diameters of the first rolling roller 41, the second rolling roller 42, the third rolling roller 43, and the fourth rolling roller 44 are almost the same because they are all formed of a base material of the same diameter. On the side surfaces of the second rolling roller 42, the third rolling roller 43, and the fourth rolling roller 44, convex and concave stripes having a semicircular cross section are alternately formed in parallel with the rotation center axis. The shape of the first rolling roller 41 will be described later.

  The lower pair of first rolling rollers 41 and the second rolling rollers 42, and the upper pair of the third rolling rollers 43 and the fourth rolling rollers 44 are disposed in parallel at predetermined intervals. A line connecting the centers of rotation of the lower first rolling roller 41 and the second rolling roller 42 and a line connecting the centers of rotation of the upper third rolling roller 43 and the fourth rolling roller 44 are inclined forward. The positions of the first rolling roller 41 and the second rolling roller 42 on the lower side are shifted forward with respect to the third rolling roller 43 and the fourth rolling roller 44 on the upper side. Send out.

  The upper third rolling roller 43 and the fourth rolling roller 44 feed cooked rice between the lower first rolling roller 41 and the second rolling roller 42. Therefore, the distance between the upper third rolling roller 43 and the fourth rolling roller 44 is wider than the distance between the lower first rolling roller 41 and the second rolling roller 42. The thickness of the cooked rice rolled into a plate shape by the rolling unit 4 is determined by the distance between the lower first rolling roller 41 and the second rolling roller 42.

  The lower pair of first rolling roller 41 and second rolling roller 42 and the upper pair of third rolling roller 43 and fourth rolling roller 44 are rotationally driven in opposite directions to each other to plate the cooked rice. Transport to the lower front while rolling into The cooked rice is rolled by the upper third rolling roller 43 and the fourth rolling roller 44 and further rolled into a plate by the lower first rolling roller 41 and the second rolling roller 42. The cooked rice rolled by the first rolling roller 41 and the second rolling roller 42 is cut in a plate-like cooked rice into an appropriate size by the cutter unit 45 moving in the front-rear direction with respect to the guide member 46 having the inclined surface. It is guided to the conveyance unit 5.

  The transport unit 5 includes a base 9 on which the cooked rice rolled by the rolling unit 4 is placed. In addition, you may replace the conveyance part 5 with the shaping | molding part which shape | molds the boiled rice conveyed from the rolling part 4 in a cylinder shape.

  The base 9 is slidably incorporated in a horizontal plane. The moving direction of the base 9 is the front-rear direction of the food forming apparatus 1. When the base 9 is retracted, and the appropriate operation for forming the cooked rice is performed, the rolling unit 4 rolls the cooked rice in synchronization with the advancing of the base 9. The cooked rice is supplied toward the base 9 while being formed to a predetermined thickness along the guide member 46 of the rolling unit 4. The cooked rice supplied to the rolling unit 4 is received by the mounting surface of the base 9 moving forward and formed into a plate.

Structure of First Rolling Roller As shown in FIG. 3, the first rolling roller 41 is paired with a second rolling roller 42 provided at a predetermined interval. The cooked rice R, which is a food, flows from the hopper 2 into the rolling unit 4. The boiled rice R which has flowed in is rolled by the upper third rolling roller 43 and the fourth rolling roller 44, and then flows into the lower first rolling roller 41 and the second rolling roller 42. The cooked rice R is formed into a plate shape by the rotating first rolling roller 41 and the second rolling roller 42.

  As described above, since the line connecting the rotation centers of the first rolling roller 41 and the second rolling roller 42 is inclined forward, the first rolling roller 41 is provided below the second rolling roller 42. . With such an arrangement, in the rolling unit 4, the second rolling roller 42 has a function of regulating the size of the cooked rice R as well as rolling the cooked rice R, and the cooked rice R when the first rolling roller 41 is formed into a plate shape Have the ability to shape the surface of

  As shown in FIG. 4, the first rolling roller 41 is, for example, a substantially columnar body such as a substantially octagonal prism. The shape of the 1st rolling roller 41 should just be a shape which can rotate in an axial direction with the 2nd rolling roller 42, and can roll rice. Therefore, as described above, the shape is not limited to the substantially octagonal prism, but may be substantially cylindrical or the like. The first rolling roller 41 has a side surface 411 for rolling cooked rice and shafts 413 provided on the bottom surfaces 412 at both ends of the side surface 411. The length L of the side surface 411 is appropriately determined depending on the type of the food to be formed, but in the case of the food forming apparatus 1 for forming sushi, it is, for example, about 180 mm.

  The side surface 411 has ridges 415 corresponding to the number of vertices on each side of the bottom surface 412. In the case where the first rolling roller 41 has a substantially cylindrical shape or the like, the ridge line 415 is not provided. The side surface 411 has a plurality of projections 414 provided to protrude from the surface.

  As shown in FIG. 5, the protrusions 414 are provided at intervals between adjacent other protrusions 414. More specifically, the protrusions 414 are provided at intervals between the other protrusions 414 adjacent in the circumferential direction or spiral direction of the side surface 411. In the present embodiment, the protrusion 414 has a rhombus shape when viewed from the side surface 411. The shape of the protrusion 414 is not limited to a substantially square in a front view as in the present embodiment, and may be, for example, a substantially elliptical shape or a substantially triangular shape. In addition, as for the magnitude | size of planar view of the projection part 414, about 20 mm x 20 mm is preferable.

  The protrusion 414 is provided at a position where one of the diagonal lines overlaps the ridge line 415. Also, another diagonal of the protrusion 414 is along the circumferential direction of the side surface 411. That is, in the protrusion 414, the first pointed end 4141 which is the apex of the rhombus points forward in the rotational direction of the first rolling roller 41. Further, in the protrusion 414, the second pointed end 4142 which is the apex of the rhombus faces the rear in the rotational direction of the first rolling roller 41.

  In the case where the shape of the protrusion 414 is a substantially polygonal shape, the apex may be a pointed end and may be disposed so as to face forward or backward in the rotational direction. Further, in the case where the shape of the protrusion 414 is a shape having no vertex (for example, an elliptical shape or the like), the position at which the direction of the ridge line of the shape represented by the inflection point changes is the tip. In this case, the pointed end may be disposed to face forward or backward in the rotational direction.

  As shown in FIG. 6, the protrusion 414 has a flat portion 4143 substantially parallel to the side surface 411 and an inclined portion 4144 provided forward in the rotational direction of the first rolling roller 41 and inclined toward the side surface 411. And That is, the inclined portion 4144 is provided on the side of the first pointed end 4141 provided on the front side in the rotational direction. In addition, the flat portion 4143 is provided on the side of the second pointed end portion 4142.

  In the first rolling roller 41, the first pointed end 4141 of the projection 414 faces the second pointed end 4142 of the other adjacent projection 414 in the rotational direction. By doing this, in the first rolling roller 41, the contact area between the protrusion 414 and the cooked rice gradually changes during rotation. For this reason, in the cooked rice, the rolling force from the first rolling roller 41 is gradually added. Similarly, the boiled rice is gradually released from the rolling force from the first rolling roller 41 also when the first rolling roller 41 leaves the boiled rice.

  That is, the cooked rice rolled by the first rolling roller 41 can realize a soft texture with the food contained air. Moreover, the 1st rolling roller 41 can eliminate the unnecessary force to the boiled rice at the time of rolling by making the thickness of the projection part 414 different before and behind a rotation direction. The first rolling roller 41 can prevent rolling-up due to the protrusion 414 biting into boiled rice by making the thickness of the protrusion 414 different before and after the rotational direction.

  In the present embodiment, the interval I1 between the rotation direction front ends (the rotation direction rear ends of the inclined portions 4144) of the flat portions 4143 of the protrusions 414 adjacent to each other in the rotation direction is, for example, 20 mm. The distance I2 between the rear end of the flat portion 4143 of the projection 414 in the rotational direction and the front end of the inclined portion 4144 of the other projection 414 adjacent in the rotational direction is 10 mm, for example. The sandwiching angle θ between the rear end of the flat surface 4143 of the projection 414 in the rotational direction and the front end of the inclined portion 4144 of the other projection 414 adjacent in the rotational direction is 45 °, for example. The height H1 from the side surface 411 of the flat portion 4143 is 4 mm, for example. Further, the height H2 from the side surface 411 of the inclined portion 4144 is, for example, 1 mm.

  As shown in the modified examples of FIGS. 7 and 8, the first rolling roller 41 may have a shape having no ridge line at the boundary between the flat portion 4143 of the protrusion 414 and the inclined portion 4144. As shown in FIG. 9, in the first rolling roller 41 of the modification, the surface of the flat portion 4143 of the protrusion 414 and the surface of the inclined portion 4144 are smoothly connected.

  In FIG. 10, the photograph which image | photographed the cooked rice shape | molded by the food forming apparatus 1 which has the 1st rolling roller 41 is shown. Moreover, in FIG. 11, the photograph which image | photographed the cooked rice shape | molded by the food-forming apparatus of the related art which does not have the 1st rolling roller 41 is shown. FIG. 10 and FIG. 11 show examples of thick-rolled thick rice, both of which are thick. The cooked rice formed by the food forming apparatus 1 having the first rolling roller 41 shown in FIG. 10 has a thickness and a distribution degree of rice grains from the appearance of the black nori seaweed N1 to N8 laid under the cooked rice. It can be seen that is uneven. On the other hand, the cooked rice formed by the food forming apparatus according to the related art without the first rolling roller 41 shown in FIG. 11 has a uniform thickness and distribution of rice grains from the appearance of nori N11 to N14. There is.

  In FIG. 12, another photograph which image | photographed the cooked rice shape | molded by the food-forming apparatus 1 which has the 1st rolling roller 41 is shown. Further, FIG. 13 shows another photograph of the cooked rice formed by the related-art food forming apparatus without the first rolling roller 41. FIG. 12 and FIG. 13 show examples of thinly-rolled thin-boiled cooked rice. It is understood that the cooked rice formed by the food forming apparatus 1 having the first rolling roller 41 shown in FIG. 12 has an uneven thickness and distribution degree of rice grains as in FIG. Moreover, compared with the cooked rice formed by the food forming apparatus of the related art, the cooked rice formed by the food forming apparatus 1 having the first rolling roller 41 has the streaks S11 to S13 of the roller appearing on the surface as shown in FIG. Hateful. For this reason, it can be seen that the cooked rice formed by the food forming apparatus 1 is softly formed.

  As described above, it is possible that the first rolling roller 41 has such uneven shapes as if the surface of the rolled food is pressed with a finger of the hand by the shapes of the protrusions 414 and the side surface 411 it can. Since the uneven uneven shape can be formed on the cooked rice R formed into a plate shape by the first rolling roller 41, the first rolling roller 41 can form an appropriate coarse and dense among the rice grains of the cooked rice R in which the cooked rice is rolled. . For this reason, the 1st rolling roller 41 can contain air in the space formed in rice R, and can improve the food texture of foodstuffs.

  Further, in the food forming apparatus 1, the first rolling roller 41 is disposed on the upper side, and the rolling process of the cooked rice forming apparatus is performed so that the second rolling roller 42 having the same shape as the conventional rolling roller is combined on the lower side to form a pair. By disposing on the downstream side in, it is possible to easily adjust the amount of cooked rice.

  In addition, since the uneven shape can be formed on the cooked rice R formed into a plate shape by the first rolling roller 41, when the cylindrical sushi roll is manufactured by wrapping the ingredients with the cooked rice R, the ingredients are well used for the cooked rice R Familiar, ingredients are hard to get out of the rice R. In addition, since rolled sushi using cooked rice R formed by the first rolling roller 41 uniformly enters ingredients into the cooked rice R, the appearance becomes better when the rolled sushi is cut.

  In addition, the first rolling roller 41 is an edge portion of the projecting portion 414 when the first rolling roller 41 rotates while rolling boiled rice by the inclined portion 4144 on the side of the first pointed end 4141 in the rotation direction of the projecting portion 414. It becomes difficult for rice to adhere to Further, by providing the inclined portion 4144 in the first rolling roller 41, it is possible to prevent so-called rolling up adhering to the first rolling roller 41 together with the plate-like cooked rice, particularly when thinly rolling the cooked rice.
