Description

  TECHNICAL FIELD The present invention relates to an apparatus for heating and cooking stir-fried foods such as baked rice and stir-fried vegetables, and more specifically, when a food material containing cooked rice is stirred with a stirring blade, the cooked rice can be stirred without excessively pressing the cooked rice. And a stirring blade used in the apparatus.

  An apparatus has been proposed in which ingredients such as cooked rice, ingredients, seasoning liquid, and water are introduced into a kettle equipped with stirring blades, and the ingredients are heated and stirred in the kettle to produce a fried food (Japanese Patent No. 2783955). No., Patent Document 1).

  However, when producing stir-fried foods such as grilled rice, if the ingredients are stirred with a spatula blade such as a spatula, the rice is sticky because it is pressed with a spatula, producing a sticky texture of cooked rice There is.

  Therefore, for example, in Japanese Patent Application Laid-Open No. 2011-110356 (Patent Document 2), a rotary shaft provided with a plurality of stirring blades is arranged in a rotary cylindrical drum, and the ingredients to be put into the drum are drums. A cooking apparatus is disclosed that is stirred by rotating and stirring blades. However, in this apparatus, since the rotating shaft is provided with a plurality of stirring blades, the cleaning operation is not easy, and once the inner surface of the drum is burnt, it is very difficult to remove the burn. Furthermore, when such a rotary drum is used, it is necessary to supply oil to the entire inner surface of the drum, so there is a disadvantage that a large amount of oil is required, and while the lower surface of the drum is heated. Since the drum is rotated, the heating area is small, so that the drum temperature rise rate is slow. Furthermore, such a cooking device is expensive.

  The applicant of the present application has proposed a stir-fried cooking apparatus using stirring blades having a relatively simple configuration in Japanese Utility Model Laid-Open No. 48-20983 (Patent Document 3). However, even with this apparatus, the agitation of the cooked rice is insufficient, and the cooked rice may be hardened.

The driving means 26 includes a case 30 provided with a motor, a power transmission mechanism (for example, a driving sprocket, a driven sprocket fixed to the upper end of the rotating shaft 34, and a driving sprocket) connected to the rotating shaft of the motor. And a chain or gear for connecting the driven sprockets 32) and a drive shaft 33.

  As shown in FIGS. 3 to 9, the stirring blade 4 includes a rotary shaft 34 attached to the drive shaft 33 of the fried food manufacturing device 1, a horizontal member 36 fixed to the lower end of the rotary shaft 34, and the horizontal member 36, a first blade member 50 fixed to one end of 36, and a second blade member 60 fixed to the other end of the transverse member 36.

  The horizontal member 36 can be composed of a plate material, a round bar, or the like, and is attached to the lower end of the rotating shaft 34 in a substantially horizontal direction. At the center position in the longitudinal direction of the transverse member 36, the transverse member 36 is fixed to the lower end of the rotating shaft 34 by screws, welding or the like.

  The first and second blade members 50, 60 are formed by bending a metal bar having a substantially circular cross section, such as stainless steel.

  The first and second blade members 50, 60 are respectively extended from the end of the horizontal member 36 toward the peripheral end of the heating pot 2, and suspended downward from the horizontal member 38. The vertical member 40 and a stirring horizontal member 42 extending in the central direction of the heating pot 2 through the bottom surface 10 of the heating pot 2 and a gap are provided at the lower end of the vertical member 40.

  The vertical member 40 is formed along the side wall surface 12 of the heating hook 2, and when the rotary shaft 34 rotates and revolves and moves to the wall side of the heating hook 2, the vertical member 40 is separated from the side wall surface 12 and the small gap. (For example, about 3 to 7 mm).

  A first projecting portion 54 projecting in a direction away from the bottom surface 10 of the heating pot 2 and a first horizontal portion close to the bottom surface 10 of the heating pot 2 are formed on the stirring lateral member 42 of the first blade member 50. 51 and a base 59 are formed.

If this interval is too small, the food material containing cooked rice may be crushed between the first horizontal portion 51 and the bottom surface 10 of the pot, and if this interval is too large, the lump of food material is the first mass. In some cases, the food material may be hardened because it passes between the horizontal portion 51 and the bottom surface 10 of the heating pot 2.

  Further, the interval L2 between the upper portion 58 and the bottom surface 10 of the heating pot 2 is set to be larger than the above-described interval L1, and is adjusted to a predetermined interval according to the size of the heating pot 2, the amount of food, the ingredients, etc. be able to. If this interval L2 is too small, the food material containing the cooked rice may not be sufficiently stirred. If this interval is too large, the lump of food material may cause the first horizontal portion 51 and the bottom surface 10 of the heating pot 2 to In some cases, the ingredients may be clumped to pass between the two.

  The configuration of the stirring lateral member 42 of the second blade member 60 is also configured in the same manner as the stirring lateral member 42 of the first blade member 50 described above.

  That is, the second projecting portion 64 projecting in the direction away from the bottom surface 10 of the heating pot 2 and the second projecting portion 64 proximate to the bottom surface 10 of the heating pot 2 are formed on the stirring lateral member 42 of the second blade member 60. A horizontal portion 61 and a tip portion 62 are formed.

  The second projecting portion 64 includes a second horizontal portion 61 and two rising portions 65 rising from the tip portion 62 and an upper portion 66 extending from the rising portion 65 in the horizontal direction. The distance between the horizontal portion 61 or the upper portion 66 and the bottom surface 10 of the heating hook 2 is configured in the same manner as in the case of the stirring lateral member 42 of the first blade member 50.

  When the rotary shaft 34 rotates once, the rotation locus of the first bent portion 54 moves relatively outside the heating pot 2 (substantially ring-like movement locus), and the second bent portion. The rotational trajectory 64 moves relatively inside the heating pot 2 (substantially ring-shaped rotational movement).

  The rotation locus of the first bent portion 54 and the rotation locus of the second bent portion 64 do not coincide with each other. Similarly, the rotation locus of the first horizontal portion 51 and the rotation locus of the second horizontal portion 61 do not match. Here, the fact that the rotation trajectories do not match means that the rotation trajectories of the two curved portions or the rotation trajectories of the two horizontal portions do not completely coincide, and when the rotation trajectories partially overlap (for example, 20 in terms of area). % Overlap) is included in the present invention.

  The distal end portion of the agitating lateral member 42 of the first blade member 50 is separated from the distal end portion of the agitating lateral member 42 of the second blade member 60, and a gap portion 68 is formed between both distal end portions.

  The distance of the gap 68 can be appropriately set according to the diameter of the heating pot 2, the revolution distance of the rotating shaft 34, and the like.

  In the above, an example in which the blade members 50 and 60 are fixed so as to face both end portions of the lateral member 36 is shown, but two pairs of blade members 50 and 60 may be fixed to the lateral member 36 or three pairs. You may fix above.

  2 to 9 show an example in which two pairs of blade members are fixed to both end portions of the lateral member 36.

  That is, the stirring blade further includes a third blade member 70 fixed to one end portion of the horizontal member 36 and a fourth blade member 71 fixed to the other end portion of the horizontal member 36.

  Similarly to the first and second blade members 50 and 60, the third and fourth blade members 70 and 71 are horizontally extended from the end of the lateral member 36 toward the circumferential end of the heating pot 2, respectively. A member 38, a vertical member 40 suspended downward from the horizontal member 38, and a lower end portion of the vertical member 40 are extended toward the center of the heating pot 2 through a bottom surface 10 of the heating pot 2 and a gap. And a stirring cross member 42 provided.

  Then, a third projecting portion projecting in a direction away from the bottom surface 10 of the heating pot 2 and a third horizontal portion adjacent to the bottom surface 10 of the heating pot 2 are formed on the stirring lateral member 42 of the third blade member 70. Are formed on the agitating cross member 42 of the fourth blade member 71, and are proximate to the bottom surface 10 of the heating pot 2 and the fourth protruding part that curves away from the bottom surface 10 of the heating pot 2. A fourth horizontal portion is formed. The rotation locus of the first bent portion 54 does not match the rotation locus of the third bent portion, and the rotation locus of the second bent portion 64 and the rotation locus of the fourth bent portion match. It is something that does not.

  Since the configuration of the third and fourth blade members 71 is the same as the configuration of the first and second blade members 50 and 60, description thereof is omitted.

  Furthermore, an upper reinforcing member 72 and a lower reinforcing member 73 that connect adjacent blade members are provided.

  Next, the operation of the fried food manufacturing apparatus of the present invention will be described.

  The stirring blade 4 having the above configuration is arranged in the heating pot 2 and fixed to the drive shaft 33, and the stirring blade 4 is rotated by the rotational drive of the drive shaft 33.

  The vertical member 40 rotates and rotates (rotates and revolves) along the wall surface of the heating kettle 2, and the stirring horizontal member 42 is placed in the heating kettle 2 with a predetermined interval along the bottom surface 10 of the heating kettle 2. Move the rotation. Ingredients including the cooked rice put into the heating pot 2 are loosened by hitting the curved portion of the stirring horizontal member 42, and the ingredients near the bottom surface 10 of the heating pot are stirred by the horizontal portion of the stirring horizontal member 42.

  Here, since the rotation trajectory of the first bent portion 54 and the rotation trajectory of the second bent portion 64 do not coincide with each other, the first blade member 50 of the first blade member 50 is arranged on the peripheral end side of the heating pot 2. After the upper portion of the food material is stirred by the projecting portion 54, the lower portion of the food material can be stirred by the second horizontal portion 61 of the second blade member 60. On the central side of the heating pot 2, the lower portion of the food material is stirred by the first horizontal of the first blade member 50, and then the upper portion of the food material is stirred by the second projecting portion 64 of the second blade member 60. can do.

  As a result, these blade members 50, 60, 70, 71 can effectively stir the food material containing cooked rice put in the heating pot 2.

  In addition, although the rotating shaft 34 usually rotates and revolves, only rotation may be sufficient.

  The manufacturing apparatus of the fried food containing ingredients, such as baked rice, and the stirring blade used for the apparatus can be provided.
