The present invention relates to a heating stir cooker of the method of scraping and rubbing while heating food ingredients and the like.

As a conventional scraping-type heating stirring pot, there is one provided with a stirring part freely supported by rotation in a heating vessel, for example. The scraping-type heating stirring pot can accommodate the agitated material such as food ingredients in the heating container, and heat-stirr the agitated material in the heating container by rotating the stirring part having the scraping blade at the tip while heating. The heating stirring is performed by scraping the agitated object heated by the rotating stirring portion from the inner circumferential surface of the heating vessel and mixing the agitated substance as a whole.

However, in the conventional scraping-type heating stirring pot, when the stirring object with high viscosity is heated and stirred, there is a possibility that the stirring object rotates together with the stirring section and the mixing efficiency is lowered.

In addition, although most of the agitated material is scraped off by a scraping wing, the agitated material remaining after a small amount of scraping adheres to the inner circumferential surface of the heating vessel. When the remaining agitated material rotates as described above, the new agitated material becomes difficult to move to the inner peripheral surface side of the heating vessel, and there is a problem that it is easy to burn and stick.

In addition, when scraping off, the agitated object adheres to the back side of the scraping blade of the stirring part in general. Scraping The back of the wing has less replacement of the agitator and stays at a high temperature. For this reason, there exists a possibility that the to-be-adhered thing which adhered and stayed may change into a solid thing etc. with the progress of heat stirring.

In addition, even when the fluid has a relatively good fluidity, it is rotated together with the shaft for transmitting the stirring part itself or the rotational driving force, and the stirring object adheres to the stirring part itself or the shaft. There is a problem in that mixing defects are likely to occur as a whole by the attached agitated object.

Prior Patent Document: Japanese Patent Laid-Open No. 2002-453

The problem to be solved by the present invention is that the conventional scraping-type heating stirring pot causes a decrease in the mixing efficiency of the highly viscous agitated material and is liable to burn, deteriorate or poor mixing.

The present invention can be heated to accommodate the agitated object in order to prevent a decrease in mixing efficiency, burning, deterioration or poor mixing even in a highly viscous agitated material, and scraping the heating vessel freely supported by rotation in the heating container. And a stirring means having a blade, and a driving means for rotating the stirring part to stir the agitated object in the heating vessel, wherein the driving means rotates the agitating part forwardly and half-turned by the half-rotation. The main feature is to apply the agitated material in the form of a film or a layer on the inner circumferential surface of the heating vessel.

The arm 37 is supported with respect to the rotation shaft 35 by the clamp portion 43 provided on the proximal end side. At the tip of the arm 37, a bracket portion 45 for attaching the scraping blade 39 is provided. The bracket portion 45 is set to have an angle of θ with respect to the shaft center of the rotation shaft 35. In this embodiment, as shown in Fig. 4, the setting angle θ is approximately 30 degrees. However, the setting angle θ is arbitrary.

The bracket portion 45 has a plate-shaped base 47. The vertical wall portion 49 extends along the axial direction of the arm 37 from the rotational front side end portion at the time of forward rotation of the stirring portion 5 at the base 47. The base 47 has a rod-shaped spring sheet 51 protruding along the axial direction of the arm adjacent to the vertical wall portion 49. Opposite walls 53 are provided on both sides in the width direction of the vertical wall portion 49 (both sides in the direction in which the paper goes straight) toward the rear side of the scraping blade 39 in the rotational direction. In the lower side of the opposing wall 53, the hole 55 which is biased and arrange | positioned to the back side of the rotation direction with respect to the said spring sheet 51 is formed through. Moreover, the stopper part 56 is provided in the opposing wall 53 at the edge part by the side of the vertical wall part 49. As shown in FIG. A stopper surface 62 made of an inclined surface is provided at the lower end of the stopper portion 56.

The scraping blade 39 is inclined so as to be inclined backward in the rotational direction rearward (arrow a direction) with respect to the inner circumferential surface 57 of the heating vessel 3. The scraping blade 39 is configured such that the wing portion 61 is supported by the engaging portion 59 coupled to the bracket portion 45 of the arm 37.

One end of the coupling portion 59 is disposed between the opposing walls 53 of the bracket portion 45. One end of the engaging portion 59 has a hole 63 formed therethrough corresponding to the hole 55 of the opposing wall 53 of the bracket portion 45, so that the hole 63 and the hole of the bracket portion 45 are formed. A coupling pin 65 is inserted between the 55. Therefore, the scraping blade 39 is rotatably coupled to the arm 37. In the engaging portion 59, a contact surface 64 is formed on a surface of the bracket portion 45 that faces the stopper portion 56. The contact surface 64 is provided with a projection 67 facing the spring sheet 51 of the bracket portion 45.

The other end side of the coupling portion 59 is coupled to the wing portion 61 by a bolt (69). The tip of the blade 61 is in contact with the inner circumferential surface 57 of the heating vessel 3 in the inclined state of the scraping blade 39.

The coil spring 41 is attached to the base 47 of the bracket portion 45 by a spring sheet 51. That is, the coil spring 41 is arrange | positioned around the spring sheet 51 of the bracket part 45, and the spring sheet 51 has penetrated the axial center part. A cylindrical cylinder 71 is provided between the coil spring 41 and the protrusion 67 of the scraping blade 39.

One end of the cylinder 71 is in contact with the coil spring 41 and the other end is in contact with the protrusion 67 of the scraping blade 39. Accordingly, the cylinder 71 is configured to transmit the elastic force of the coil spring 41 to the scraping blade 39 via the protrusion 67.

That is, as shown in Fig. 6 (a), the coil spring 41 presses the scraping blade 39 through the cylinder 71 at the time of forward rotation and stops toward the inner circumferential surface 57 of the heating vessel 3 to elastically compress it. It is supposed to. In addition, when the scraping vane 39 rotates halfway, the cylinder 71 is pushed up by the protrusion 67 of the scraping vane 39 as shown in Fig. 6 (b), and the elastic force of the coil spring 41 is increased. Resist move. Therefore, the scraping blade 39 is able to swing against the elastic force of the coil spring 41.

Then, the scraping blade 39 has a protrusion 67 in contact with the stopper portion 56 of the bracket portion 45 during the forward rotation of the stirring portion 5, with respect to the inner peripheral surface 57 of the heating vessel 3 The fluctuation is controlled within a certain range in the near direction. On the other hand, at the time of half rotation of the stirring section 5, the contact surface 64 is in contact with the stopper surface 62 of the stopper 56 of the bracket portion 45, so that the heating vessel 3 of the scraping blade 39 The fluctuation of the inner circumferential surface 57 is controlled within a predetermined range in the direction opposite thereto.

[The effect of heating stirring pot by scraping and rubbing]

Fig. 7 is a schematic cross sectional view showing a relationship between a heating container and an agitated object during heating stirring.

In this embodiment, a highly viscous adzuki bean-producing material containing water is used as agitated material. When heat-stirring a material, the partition cover 31 of the heating container 3 is removed previously, and the partition cover 31 is accommodated as the lid accommodation part 17. Then, the material is introduced from the upper opening of the opened heating container 3. At this time, the weight of the input material is detected by the weight sensor 23. In the case of weight detection, the divided cover 31 is also included in the detection, and after the mounting of the partition cover 31, it is not necessary to perform a calculation considering the detachment of the partition cover 31 during the weight detection control during heating stirring. The control software can be simplified. In addition, since the piping unit 12 is grounded independently with respect to the support frame 15 side by the flexible pipe 32, the influence of the weight of the piping unit 12 at the time of the weight detection by the weight sensor 23 is carried out. Is suppressed, and accurate detection can be performed.

After the material is introduced, the partition cover 31 is mounted on the upper opening of the heating vessel 3 again, and the drive motor 7 is driven to be controlled by the control box 9. By the related control, the stirring section 5 is rotated forward and half at predetermined intervals. For example, after three rotations of the forward rotation, three rotations of the half rotation are repeated until the material reaches the desired weight by water evaporation. However, the number of revolutions of the forward and half revolutions can be set arbitrarily according to the material, the state in which moisture has been lost by heating, and the mixing state. Do.

When the forward rotation and the half rotation are repeated for each predetermined period, the rotation of the material with the stirring section 5 can be suppressed or eliminated by the reverse rotational force, and the material can be flowed.

And at the time of forward rotation, the material can be scraped off by the scraping blade 39 of the stirring part 5. That is, since the scraping blade 39 is inclined backward toward the rearward direction of rotation, the angle for scraping action with respect to the inner circumferential surface 57 of the heating container 3 is slidably rotating at an acute angle. For this reason, the scraping blade 39 guides and flows material away from the inner peripheral surface 57 of the heating container 3. Thus, the material is heated at the inner circumferential surface 57 of the heating vessel 3 and the unheated portion thereof is mixed to perform heating stirring as a whole.

In addition, during the forward rotation, the scraping blade 39 is pressed against the inner circumferential surface 57 of the heating vessel 3 by the resistance of the material together with the elastic force of the coil spring 41, so that it can be reliably scraped off.

On the other hand, at the time of half rotation, the material can be rubbed by the scraping blade 39 of the stirring part 5. That is, since the scraping blade 39 is inclined to the rear side in the rotational direction at the time of forward rotation, the angle for the scraping action with respect to the inner circumferential surface 57 of the heating vessel 3 at the time of half rotation rotates while making an obtuse angle. For this reason, the scraping blade 39 guides the inner unheated material toward the inner circumferential surface 57 side of the heating vessel 3.

The flowed material is pressed in the rotational direction by the scraping vane 39 and enters between the tip of the scraping vane 39 and the inner circumferential surface 57 of the heating vessel 3 to the inner circumferential surface 57 of the heating vessel 3. Rubbed against. At this time, the scraping blade 39 swings and floats from the inner circumferential surface 57 of the heating vessel 3 to resist the elastic force of the coil spring 41, and the contact surface 64 is the arm 37 side. Contact with the stopper face 62. The reaction force due to this contact can be reliably applied as a rubbing force on the material. For this reason, the material is reliably applied to the inner circumferential surface 57 of the heating vessel 3 in the form of a film or a layer.

As shown in FIG. 7, the spread | dipped material 58 is spread | coated on the material 6 which remained at the time of scraping forward rotation. As a result, the residual material 60 undergoes water movement from the above-coated material 58, heat transfer to the above-coated material 58 occurs, and overheating is prevented. Therefore, the residual material 60 is prevented from being burned out by the water movement and the heat movement. The residual material 60 is in a swelled state by the movement of moisture, and is easily scratched at the next forward rotation.

At the time of the half rotation, since the backing of the scraping blade 39, which was not used at the time of the forward rotation, is performed to rub the material, the material moves to slide the back of the scraping blade 39 and moves to this part. The retention of adhesion of the material can be suppressed.

In addition, since the direction of movement is reversed at the time of half rotation by the forward rotation and the half rotation, the rotational force in the reverse direction is applied to the material, so that the material 37 rotates together with the arm 37, the rotation shaft 35 and the like of the stirring section 5. In addition, the adhered material can also be flowed to suppress the adherence.

As described above, in the present embodiment, the heated material on the inner circumferential surface 57 of the heating vessel 3 is moved to the scraping blade 39 by the inner circumferential surface 57 by the scraping blade 39 in the forward rotation. A small amount of material remains on the inner circumferential surface 57, but the stirring part 5 is rotated halfway before the residual material 60 is overheated (sticked). At this time, since the scraping blade 39 which pushes and rotates the material moves in the reverse direction, the material temporarily stops moving. As a result, the inertia of rotation can be destroyed, and the co-rotation between the scraping blade 39 and the material can be eliminated. Thereafter, the reverse side of the scraping blade 39 is operated to press the material.

The scraping blade 39 has an acute angle for the scraping action with respect to the inner circumferential surface 57 of the heating vessel 3, making it easy to move the material from the surface during scraping. When the scraping vane 39 is rotated halfway, the scraping vane 39 operates to rub the material in the rotational direction forward on the inner circumferential surface 57 of the heating vessel 3. The scraping blade 39 is movable and is pressed against the inner circumferential surface 57 of the heating vessel 3 by the coil spring 41 at the time of scraping forward rotation, but from the inner circumferential surface 57 at the time of half rotation rubbing. It comes to mind By this rise, the inner circumferential surface 57 can be rubbed with a material (agitated material) containing moisture that is not heated.

Therefore, the material 60 remaining on the inner circumferential surface 57 of the heating vessel 3 at the time of forward rotation is mixed with the rubbed material (stirred material) 58 to suppress heating by itself. That is, the residual material 60 is heated together with the material 58 rubbed on the inner circumferential surface of the heating vessel 3, and once again switched to forward rotation, it is scratched and united with the surrounding material.

As described above, by periodically switching between the forward rotation and the half rotation, overheating and sticking of the material (stirred material) on the inner circumferential surface 57 of the heating vessel 3 can be suppressed, and the heat transfer efficiency can be improved. In addition, it is possible to prevent a decrease in the mixing efficiency due to the co-rotation.

[Experiment result]

The experimental results for the case of performing only the forward rotation and the forward rotation and the half rotation during heating stirring will be described.

The first test result is the rotational speed of the stirring unit (5) at 15 rpm, the forward and half rotations respectively three rotation cycles, the material is 80 kg of red bean red bean, 44 Kg per granule, 12 Kg of egg yolk, water It is obtained from Hwangmi bean jam prepared with 5.3 Kg.

When only forward rotation was performed, the material rotated together with the scraping blade 39 to come into a state of sliding the inner circumferential surface 57 of the heating vessel 3. For this reason, material did not flow in the heating container 3, and stirring efficiency became remarkably low. Even in this sliding state, the material could be heated by the inner circumferential surface 57 of the heating vessel 3, but since the material only partially contacts the inner circumferential surface 57 of the heating vessel 3, the material and the heating vessel 3 Since an air layer exists between the inner circumferential surface 57 of), the heating efficiency of the material is also significantly lowered. As a result, the heating and stirring time became long for 2 hours 30 minutes.

In this case, a localized heat is generated in which only the material remaining on the inner circumferential surface 57 of the heating vessel 3 is heated at the time of scraping, and burned on the entire surface of the inner circumferential surface 57 of the heating vessel 3.

On the other hand, when the forward rotation was performed three times and the semi-rotation was performed three times, the rotation was half-turned at the rotational speed at which the co-rotation of the material occurred by the forward rotation, and the co-rotation of the material was eliminated, so that mixing and agitation could be performed smoothly. For this reason, the fall of mixing efficiency and heating efficiency can be prevented, and the heating stirring time was 1 hour and 20 minutes, and it could be set as short time about 53% of only a forward rotation. Moreover, it was possible to suppress the sticking and to make the quality sufficient.

The second test result is the rotational speed of the stirring unit (5) at 15 rpm, forward rotation and half rotation each of two rotation cycles, the material is bovine soybean paste red bean 82.8 Kg, granulated sugar 49.7 Kg, Sangbaek sugar (上 白糖) 6.6 Kg, Sangnam bun (上 南 粉) 2.65 Kg, commercial flour (上 用 粉) was obtained from Choonwoo bean paste prepared with 2.65 Kg.

This second test result was the same as the first test result.

[Effect of Embodiment]

In the present embodiment, the stirring object 5 having the highly viscous agitated object in the heating container 3 and the blade 39 scraping off the tip while heating is rotated by the driving motor 7, The stirring of the to-be- stirred object can be performed. At the time of heating and stirring, the drive motor 7 rotates the stirring part 5 forward and half to prevent the agitated object from rotating together with the stirring part 5, thereby suppressing a decrease in the mixing efficiency. Can be.

In addition, the heating stirring pot 1 of scraping and rubbing can apply the agitated object to the inner circumferential surface 57 of the heating vessel 3 in a film form or layer form by the half rotation. For this purpose, the non-heated agitated material with more moisture can be applied to and mixed with the agitated material remaining on the inner circumferential surface 57 of the heating vessel 3 when scraping forward rotation. Therefore, it is possible to reliably suppress the burning by the remaining agitated material.

In addition, in this embodiment, by performing forward rotation and half rotation, both the surface of the scraping blade 39 and the back of the scraping blade 39 can be restrained from adhering to the agitated object to the scraping blade 39 by heating and stirring. Can be. Therefore, it is possible to reliably suppress that the agitated substance remaining on the scraping blade 39 deteriorates due to the progress of heating stirring.

In addition, in this embodiment, since the rotational force in the reverse direction is applied in the forward rotation and the half rotation, the arm 37 of the stirring section 5, the rotational shaft 35, and the like can be suppressed from rotating together. Therefore, the mixing defect of agitated material can be suppressed. In addition, the agitated object attached to the arm 37, the rotating shaft 35, or the like can also be flowed in the forward rotation and the semi-rotation, so that the adherent flow can be suppressed. Therefore, it is possible to reliably suppress that the agitated substance adhering to the arm 37, the rotating shaft 35, or the like is insufficiently mixed or deteriorated (concentrated, dried, or the like) as the stirring is progressed.

In the present embodiment, since the scraping blade 39 is inclined so as to be inclined backward in the rotational direction rear at the time of forward rotation with respect to the inner circumferential surface 57 of the heating vessel 3, the inner circumferential surface of the heating vessel 3 at half rotation ( 57) It can flow reliably toward the side, and it can apply | coat a to-be-stirred object more reliably to the inner peripheral surface 57 of the heating container 3 in film form or layer shape.

In this embodiment, since the scraping blade 39 is supported to be able to swing in a predetermined range around the rotation direction, the scraping blade 39 swings so as to be separated from the heating container 3 during the half rotation, and the heating container 3 With respect to the inner circumferential surface 57 of), the agitated material can be applied more reliably in the form of a film or a layer.

In the present embodiment, the stirring part 5 is freely coupled to the tip of the arm 37 supported by the rotating shaft 35 driven by the drive motor 7 with a coupling pin, and the arm 37 and Between the scraping blades 39, the scraping blades 39 are rotated and elastically compressed to provide a coil spring 41 that is pressed toward the inner circumferential surface 57 side of the heating vessel 3. Therefore, the scraping blade 39 is reliably rocked to a certain range during the half rotation while the scraping blade 39 is firmly pressed against the inner circumferential surface 57 of the heating vessel 39 at the time of forward rotation, It is possible to alternately scrape and apply the material.

[Example 2]

Hereinafter, Embodiment 2 of the present invention will be described with reference to FIG. 8 is a cross-sectional view showing the scraping blade and its attachment portion used in the heating stirring pot of the scraping and rubbing method according to the present embodiment.

In the present embodiment, instead of the coil spring 41, as shown in Fig. 8, the scraping blade (scraping blade) provided by the restricting pin 75 and the engaging portion 77 provided on the arm 37A side and the scraping blade 39A side. 39A) enables a range of movements.

That is, the engaging pin 65 and the regulating pin 75 are provided in the front-end | tip of the arm 37A of the stirring part 5A at predetermined intervals. Scraping wing 39 is composed of a wing portion 61A is integrally provided to the coupling portion 59A supported between the coupling pin 65 and the regulation pin 75. The coupling portion 59A is provided with a coupling recess 79 having a curvature substantially the same as that of the coupling pin 65A at one end thereof. As the engaging recess 79 engages the engaging pin 65A, the scraping blade 39A is rotatable around the engaging pin 65A. The other end of the engaging portion 59A is provided with a loose fitting recess 81 as the engaging portion formed larger in the rotational direction of the scraping blade 39A than the regulating pin 75. The loose fitting recesses 81 are loosely fitted to the restricting pins 75 so that the scraping blade 39A is restricted to rotate over a predetermined range. That is, the scraping blade 39A is pressed against the inner circumferential surface 57 side of the heating vessel 3 by the resistance of the agitated object at the time of forward rotation, thereby increasing the scraping effect, and the resistance of the agitated object at the time of half rotation. As a result, the effect of rubbing the agitated object onto the inner circumferential surface 57 by moving in the direction away from the inner circumferential surface 57 can be improved. As shown by the double-dotted line, fluctuation in a certain range is possible.

Therefore, in this embodiment, in addition to being able to exhibit the same operational effects as in the above embodiment, the structure can be simplified compared with the case of using the coil spring 41.

[Modifications]

In this modification, as shown in Fig. 9, the regulating pins 83 and 85 are provided on both sides in the rotational direction of the scraping blade 39B, and as indicated by the double-dotted line, the predetermined range of the scraping blade 39B is fixed. Oscillation in is enabled. The scraping blade 39B is provided with an engaging recess 87 corresponding to the regulating pin 85 on one side. The engaging recess 87 is coupled to the regulating pin 85 even when the scraping blade 39B contacts the regulating pin 83 on the other side, so that the scraping blade 39B can be supported.

As mentioned above, although the Example of this invention was described, this invention is not limited to this, Various changes accompanying an element are possible. For example, in the above embodiment, the scraping blade can be swinged to a certain extent with respect to the arm, but it is sufficient to fix the arm unstable to the arm depending on the physical properties of the agitated object.

In addition, the scraping blade is a contact type in which the tip of the wing portion is scraped with the inner peripheral surface of the heating container in contact with the inner peripheral surface. . However, even in the case of non-contact type, a gap for the purpose of preventing wear of the scraping vane, for example, a gap of about 5 to 10 mm is provided between the scraping vane and the inner circumferential surface 57 of the heating vessel 3 and the contact type. You can get almost the same effect.

According to the present invention, the agitated part such as food material is accommodated in the heating container, and the stirring part is rotated by the driving means while heating to stir the agitated material in the heating container. At the time of rotation driving, the stirring part is rotated forward and half to prevent the agitated object from rotating together with the stirring part, and the anti-rotation of the stirring part is applied to the inner circumferential surface of the heating vessel in the form of a film or layer. It is possible.

Therefore, even in the case of a highly viscous agitated material, it is possible to prevent a decrease in the mixing efficiency and to mix and agitate the agitated material remaining on the inner circumferential surface of the heating vessel and the agitated material applied in the form of a film or layer on it. You can prevent it.

In addition, by performing forward and half rotation, both the surface of the scraping blade and the back surface can be used, and the adhesion retention of the agitated object to the scraping blade is suppressed, and the attachment retention of the agitator is suppressed by the scraping blade. This can suppress deterioration caused by long-term stay on the blades.

In addition, the rotational force in the reverse direction is applied by the forward rotation and the semi-rotation to suppress the co-rotation and adhesion of the agitated object to the stirring portion, thereby making it possible to reliably suppress poor mixing.
