 When manufacturing foods such as jams, soups, sauces, etc., for example, an oblique stirring device is used to heat and stir the raw materials. The oblique shaft stirring device is disclosed, for example, in Japanese Utility Model Laid-Open No. 1-43152. As shown in FIGS. 3 and 4, this apparatus has a cylindrical container 61 for containing the raw materials to be stirred, and a stirring shaft 62 inserted in an inclined state from the upper end opening of the container 61. ing. The stirring shaft 62 is rotatably driven by a motor 66, and the center portion of a stirring arm 63 curved in an arc shape along the inner surface of the container 61 is fixed to the tip portion thereof. There is. The stirring arm 63 is adapted to move along the bottom surface of the hemispherical container 61 by the rotation of the stirring shaft 62. The stirring arm 63 is provided with a plurality of stirring blades 64 so as to be in sliding contact with the bottom surface of the container 61. A cutter shaft 67 is inserted vertically from the upper end opening into the container 61 so that the stirring shaft 62 and the stirring arm 63 do not interfere with each other, and the lower end of the cutter shaft 67 is the lower end of the container 61. Reaching above the stirring arm 63 in the section. A horizontal cutter blade 68 is provided at the lower end of the cutter shaft 67.

In such an oblique shaft stirring device, the stirring shaft 62 is rotated in the direction of the arrow B, whereby the stirring arm 63 is circulated along the inner surface of the container 61, and the raw material in the container 61 is fed to the stirring arm 63. Stirred by 63. Further, the stirring operation of the stirring arm 63 is promoted by the sliding contact of the stirring blades 64 provided on the stirring arm 63 with the inner surface of the container 61. In addition, at a position above the stirring arm 63 at a position eccentric from the lower axial portion of the container 61, the raw material that is not sufficiently stirred by the stirring arm 63 and the stirring blades 64 is a horizontal cutter blade.

[0004]

[Problems to be solved by the device]

 In such an inclined shaft stirring device, the stirring arm 63 attached to the stirring shaft 62 has its center portion attached to the lower end portion of the inclined stirring shaft 62, and is rotated by the rotation of the stirring shaft 63. , Moves along the hemispherical bottom surface of the container 61. As a result, the raw material that is agitated as the agitating arm 63 moves in the orbit is biased to the downstream side in the moving direction of the agitating arm 63 in the container 61 (see the chain double-dashed line in FIG. 3). Such a deviation of the raw material is slightly eliminated by the cutter blade 68 in the horizontal state. However, the cutter blade 68 is horizontally attached to the lower end portion of the vertically inserted stirring shaft 67 so as not to interfere with the stirring arm 63 from the upper end opening of the container. The position of is limited within the container 61. Therefore, the deviation of the raw material in the container 61 cannot be sufficiently eliminated. When the raw materials become uneven in this way, the raw materials are not uniformly heated, uneven heating occurs, and the quality of the manufactured product is significantly deteriorated.

The present invention solves such a problem, and an object thereof is to sufficiently stir the raw material in the container to be heated without stagnating, and thus to uniformly heat the material. The object is to provide an oblique stirring device.

Be stirred. As a result, uneven heating of the raw material is suppressed.

[0008]

【Example】

 An embodiment of the present invention will be described below. As shown in FIG. 1, the oblique stirring apparatus of the present invention comprises a container 20 for containing and heating raw materials. This container 20 is formed in a cylindrical shape with an open upper end, and its bottom surface 21 is substantially hemispherical. A steam chamber 23 is formed outside the bottom surface 21, and the bottom surface 21 of the container 20 is heated by the heat of steam supplied to the steam chamber 23 to heat the raw material in the container 20. The container 20 is supported by the frame 24.

A rotation speed variable motor 32 with a speed reducer is fixed to the upper surface of the frame 24, and the rotation speed of the motor 32 is controlled by a control device 40. The stirring shaft 30 is connected to the output shaft 31 of the motor 32, and the stirring shaft 30 is inserted into the container 20 in an inclined state from the upper end opening of the container 20. The stirring shaft 30 intersects the axis of the container 20 at an angle of about 40 degrees and is rotated in the direction of arrow B by a motor 32. The lower end of the stirring shaft 30 is close to the position off the axis of the bottom surface 21 of the container 20, and an arc-shaped stirring arm 33 extending about 270 degrees in the circumferential direction is attached to the lower end of the stirring shaft 30. ing. The stirring arm 33 is attached to the lower end of the stirring shaft 30 at the center in the circumferential direction so as to face the entire bottom surface 21 of the container 20 with a slight gap. The stirring arm 33 has a plurality of stirring blades 34 slidably contacting the bottom surface 21 of the container 20. Therefore, when the stirring shaft 30 is rotated in a predetermined direction, the stirring arm 33 orbits along the bottom surface 21 of the container 20 to stir the raw material in the container 20. At this time, the respective stirring blades 34 attached to the stirring arm 33 promote the stirring by the stirring arm 33.

A frame 24 supporting the container 20 is provided with a speed-reducible auxiliary motor 11 with a speed reducer adjacent to the motor 32. The auxiliary motor 11 is also controlled by the control device 40 independently of the motor 32. The output shaft 12 of the auxiliary motor 11 is located near the axial center of the container 20, and the rotation shaft 10 is connected to the output shaft 12. The lower end of the rotating shaft 10 is located on the downstream side of the orbiting movement region of the stirring arm 33 in the container 20, and the rotating shaft 10 is opened from the upper end opening of the container 20 so as not to interfere with the stirring shaft 30 and the stirring arm 33. , Is inserted in the container 20 in an inclined state. A rotating body 14 is provided at the lower end of the rotating shaft 10. The rotating body 14 is in the form of a disc that is orthogonal to the rotating shaft 10 so as to be slightly inclined with respect to the horizontal, and the upper surface and the lower surface of the rotating body 14 are concentrically aligned. Blades are installed.

The rotating shaft 10 can change the inclination angle inserted into the container 20. Therefore, by changing the inclination angle of the rotary shaft 10, the position of the rotary body 14 provided at the lower end of the rotary shaft 10 in the container 20 is changed.

In the oblique shaft agitator having such a configuration, in a state where the raw material is put into the container 20, steam is allowed to flow through the steam chamber 23 to heat the container 20 and the motor 32 is driven. , Rotate the stirring shaft 30. As a result, the stirring arm 33 orbits along the bottom surface 21 of the container 20, and the heated raw material in the container 20 is stirred by the stirring arm 33. By the circular movement of the stirring arm 33, each stirring blade 34 attached to the stirring arm 33 promotes the stirring action of the raw material. The stirring arm 33 stirs the raw material in the container 20 so as to scoop it up, so that the raw material stays in the container 20 at the downstream side in the orbital movement region of the stirring arm 33 along the bottom surface 21 of the container 20. The rotating shaft 10 inserted in an inclined state is rotated, and the rotating body 14 attached to the lower end of the rotating shaft 10 rotates. As a result, the raw material staying in the container 20 is diffused, and the raw material in the container 20 is uniformly stirred without staying throughout. As a result, the raw material in the container 20 is uniformly heated without uneven heating.

Since the tilt angle of the rotary shaft 10 inserted into the container 20 is adjustable, the rotary body 14 can be positioned at a position where the raw material stays in the container 20, and therefore, The retention of the raw material in the container 20 can be prevented more reliably, and the raw material can be stirred more uniformly.

[0014]

[Effect of the device]

 In the inclined shaft stirring device of the present invention, since the rotating shaft is inserted in the container in an inclined state as described above, the lower end portion of the rotating shaft can be positioned at an arbitrary position where the source flow stays. Therefore, since the lower end of the rotating shaft is located at a position where the raw material can stay in the container and the rotary body attached to the lower end can prevent the source flow from staying, It can be stirred uniformly and sufficiently.
