On the premise of a food dough mixer having a spiral stirrer 3 that rotates in the same direction as the ball 2, the stirrer 3 in a vertical state is supported on the upper case 1a of the mixer body 1 so as to be able to rotate. In addition, it is characterized in that it is provided with an inclination raising / lowering means 4 for inclining and raising the stirring bar 3 at an angle θ inclined upward toward the rotation center line O of the ball 2.

  The inclination raising / lowering means 4 will be described in detail. The inclination raising / lowering means 4 includes, as shown in FIGS. 2 and 3, an inclination raising / lowering part 5 that supports the stirrer 3 so as to be capable of rotating, and a later description of the inclination raising / lowering part 5. An operating shaft portion 6 that is connected to the installation piece 9 that reciprocates with the inclination angle θ, and an operation handle 7 that is an operation portion that reciprocates the operating shaft portion 6. A screw surface 6a is provided at the tip.

  The inclined raising / lowering section 5 has a pair of guide shafts 8 extending with the inclination angle θ, and an erection piece 9 installed on the upper end of each guide shaft 8, and as shown in FIG. A connecting hole 11 is formed in the center of the shaft so that the operating shaft 6 is rotatably connected by a known annular bearing 10.

  Further, an upper fixing piece 12A facing the installation piece 9 below the installation piece 9 and a lower fixing piece 12B arranged at a distance below the upper fixation piece 12A on the mixer body 1 side are provided with a pair of fixing walls 13. Is provided.

  A pair of guide holes 14A for loosely inserting the guide shafts 8 are formed in the upper fixed piece 12A, and a slow insertion hole 15 for loosely inserting the tip screw surface 6a of the operating shaft portion 6 between the guide holes 14A. And a screw hole 17 is formed in the lower opening edge of the loose insertion hole 15 via a nut member 16. In the present invention, the nut member 16 is not provided on the upper fixing piece 12A, and a screw groove is directly formed in the loose insertion hole 15 to form the screw hole 17, depending on the implementation.

  The lower fixed piece 12B is formed with a pair of guide holes 14B for loosely inserting the guide shafts 8 at positions corresponding to the pair of guide holes 14A.

  Accordingly, the tip screw surface 6a of the operating shaft portion 6 rotatably connected to the inclined lifting portion 5 is screwed into the screw hole 17 of the upper fixing piece 12A, and each guide shaft of the inclined lifting portion 5 is also engaged. 8 is loosely inserted into the corresponding guide holes 14 </ b> A and 14 </ b> B, and the operating shaft 6 is rotated forward or counterclockwise with the operation handle 7, so that the operating shaft 6 is moved with respect to the screw hole 17. By reciprocating, the inclined lifting unit 5 can be moved up and down steplessly via the guide shafts 8.

  Further, only the inclined raising / lowering portion 5 supports the stirring bar 3 so as to be capable of rotating, so that the mixer body 1 is complicated and enlarged while allowing the stirring bar 3 to be tilted up and down. There is no fear.

  As shown in FIG. 5, the thread of the thread surface 6a of the operating shaft portion 6 is trapezoidal in cross section, so that the tip thread surface 6a of the operating shaft portion 6 and the screw hole 17 of the upper fixing piece 12A are connected. It is firmly screwed in and the operating shaft portion 6 does not inadvertently reciprocate.

  In the present invention, the operation handle 7 serving as the operation unit only needs to be able to rotate the operation shaft unit 6, and does not exclude the use of a known manual or automatic rotating device as the operation unit.

  Here, the rotation mechanism of the stirrer 3 will be described in detail. As shown in FIG. 1, the rotation of the motor 18 is transmitted to the transmission shaft 20 having the universal joint 19 via the pulley P1, the timing belt B1, and the pulley P2. This is transmitted from the transmission shaft 20 to the rotation drive shaft 21 via the pulley P3, the timing belt B2 and the pulley P4, and the agitator 3 is rotated (spinned) by the rotation drive shaft 21.

  Therefore, the inclined lifting / lowering unit 5 that supports the stirrer 3 so as to rotate is coupled to the transmission shaft 20 and the rotary drive shaft 21 so as to be rotatable using a known annular bearing 10, as shown in FIG. Become.

  In the rotating mechanism of the stirrer 3 described above, when the inclined lifting / lowering part 5 moves up and down, the movement in the direction of the rotation center line O (movement in the X direction in FIG. 1) related to the inclined lifting and lowering is an upper part. Allowed by the long holes 22 and 23 drilled in the case 1a and the universal joint 19 and moved upward (moved in the Y direction in FIG. 1), the open space 1b of the upper case 1a and the universal joint 19 Allowed by.

  As for the rotation mechanism of the ball 2, the rotation of the motor 18 transmitted to the pulley P2 is transmitted to the rotation drive shaft 24 through a known rotation mechanism, and the ball 2 is rotated (autorotated) by the rotation drive shaft 24. It is a mechanism to do.

  When producing food dough using such a food dough mixer of the present invention, first, raw materials are charged into the ball 2, then the ball 2 is rotated by the motor 18 and the stirrer 3 is moved to the ball 2. Rotate in the same direction as above, stir and mix the above-mentioned raw materials.

  The stirring and kneading of the raw materials described above is performed in cooperation with the inner side surface 2a and inner bottom surface 2b of the rotating ball 2 and the side portion 3a and bottom portion 3b of the rotating stirring member 3.

  In other words, the inner surface 2a of the ball 2 and the side portion 3a of the stirrer 3 are each rotated through a certain clearance (side clearance) C1, whereby the raw material is stirred and the flour in the raw material is The raw material that is viscous by the stirring is pressed against the inner side surface 2a of the ball 2 by the side portion 3a of the stirrer 3 to perform kneading. Similarly, the inner bottom surface 2b of the ball 2 and the bottom portion 3b of the stirrer 3 are each rotated through a certain clearance (bottom clearance) C2, whereby the raw material is stirred and the flour or the like in the raw material is stirred. Hydration is promoted, and the raw material that is viscous by the stirring is pressed against the inner bottom surface 2b of the ball by the bottom 3b of the stirrer 3 to perform kneading.

  Accordingly, the width of the side clearance C1 and the bottom clearance C2 affects the time to hydration of raw materials and the chaotic force, and thus greatly affects the dough production time and dough viscosity. It becomes necessary to adjust the clearance C1 and the bottom clearance C2 at the same time. If the chaos force is too strong, not only the dough but also the ball 2 and the stirrer 3 are affected. In the worst case, the ball 2 and the stirrer 3 are damaged. It is necessary to adjust the part clearance C1 and the bottom clearance C2 at the same time.

  When a solid material such as a chocolate chip or a small piece of fruit or cereal is added as a secondary raw material, it is necessary to adjust both the clearances C1 and C2 at the same time according to the size of the solid solid material. Occurs.

  Accordingly, in the present invention, as shown in FIG. 6, the side clearance C1 and the bottom clearance C2 are simultaneously adjusted by the inclined lifting means 4.

  That is, the operating shaft portion 6 is rotated forward or counterclockwise by the operation handle 7 of the tilt raising / lowering means 4 and reciprocated with respect to the screw hole 17 formed in the upper fixing piece 12A on the mixer body 1 side. The tilting lift 5 connected to the operating shaft 6 is tilted up and down with a tilt angle θ through the guide shafts 8 and is supported by the tilt lift 5 so as to be rotatable. As a result of the above-described stirrer 3 also being tilted up and down, the side clearance C1 and the bottom clearance C2 can be adjusted at the same time, and the desired dough production time, dough viscosity, and the like can be easily obtained.

  In addition, the ball 2 and the stirrer 3 can be effectively prevented from being damaged, and the clearances C1 and C2 can be adjusted according to the size of the solid material of the secondary raw material. Can be prevented.

  The side clearance C1 can be widened up to a width indicated by C1 'in the drawing, and can be adjusted within this range. Similarly, the bottom clearance C2 can be widened up to a width indicated by C2 'in the drawing, and can be adjusted within this range.

  Simultaneous adjustment of the side clearance C1 and the bottom clearance C2 is performed by moving the stirrer 3 in the X direction and the Y direction in FIG. The angle θ of the tilting up and down movement is set based on the optimum adjustment ratio of the side clearance C1 and the bottom clearance C2, and when the angle θ is changed, the guide shaft 8 and the installation related thereto are installed. The arrangement of the piece 9, the fixed wall 13 and the upper fixed piece 12A and the lower fixed piece 12B related thereto can be adjusted and changed.

  When adjusting the clearance described above, the inclined elevating part 5 can be easily moved up and down by simply rotating the operating shaft part 6, and the inclined up and down movement is loosely inserted into the guide holes 14A and 14B. By using the shaft 8, stable tilting and raising / lowering motion without shaking can be ensured.

  Further, the tilting lift 5 can be lifted and lowered steplessly by the reciprocating motion of the operating shaft 6, and the clearance adjustment can be finely performed.

  As described above, in the food dough mixer according to the present invention, the stirrer 3 is tilted up and down by the tilting lifting and lowering means 4 including the tilting lifting and lowering portion 5, the operating shaft portion 6 and the operation handle (operating portion) 7. Thus, both of the side clearance C1 between the inner side surface 2a of the rotating ball 2 and the side portion 3a of the rotating stirrer 3 and the bottom clearance C2 between the inner bottom surface 2b of the ball 2 and the bottom portion 3b of the same stirring bar 3 are obtained. While adjusting simultaneously, raw materials can be stirred and kneaded to produce food dough, and the desired dough production time and dough viscosity can be easily obtained.

  When the produced dough is taken out or when the balls 2 and the stirrer 3 are cleaned, if the stirrer 3 is moved to the top by the inclined raising / lowering means 4, Cleaning work is easy and convenient.

  In the present invention, a known reciprocating device for a shaft-like member such as an air cylinder or a worm gear is adopted as the tilting raising / lowering means 4 and the device is disposed with a tilting angle θ. Further, the movement of the stirrer 3 in the direction toward the rotation center line O (X direction in FIGS. 1 and 6) and the upward movement (Y direction in FIGS. 1 and 6) are urged separately. Thus, the case where the stirrer 3 is moved up and down in an inclined manner is not excluded.
