Description

  The present invention relates to an agitation processing apparatus suitable for agitation processing of hard materials and the like.

  As a conventional stirring processing apparatus of this type, there is a cooking stirring apparatus described in Patent Document 1, for example. This cooking stirrer includes a cooking pot having an upper wall portion on the upper side of a spherical bottom, a stirring shaft having an action portion inserted and disposed in the cooking pot, and a bottom portion attached to the stirring shaft by rotation of the stirring shaft. A support rod provided with a plurality of scraping blades that scrape and slide the inner surface, and a stirring motor that is disposed outside the cooking pot and rotates the stirring shaft. The stirring shaft is disposed obliquely with respect to the cooking kettle, one end of the stirring shaft is rotatably supported on the inner surface of the bottom portion by the first bearing means supported by the spherical surface, and the other side of the stirring shaft is the second bearing means. Thus, the upper wall portion is rotatably supported by the upper wall portion, and the upper wall portion is penetrated and interlocked with the stirring motor.

  Accordingly, since the stirring shaft is disposed obliquely and the stirring shaft is supported by the first and second bearing means, the stirring shaft is supported at both ends, which is suitable for stirring a hard material while being an oblique shaft. In addition, the second bearing means side can be prevented from being immersed in the part to be stirred, and even in the food stirring process, the object to be stirred can be made difficult to enter the second bearing means, which is also sanitary satisfactory. It was possible.

  However, in the conventional structure, since the bearing socket of the second bearing means is fixed to the upper wall portion by welding, the angle of the stirring shaft is likely to be shifted by welding, and the scraping function of the scraping blade may be impaired. was there.

  The motor frame 25 is fastened and fixed to the second coupling flange 79 of the bracket 27 by stud bolts 81 and nuts 83.

[Bearing alignment]
FIG. 10 is a cross-sectional view showing assembly of the stirring shaft.

  By aligning the first and second bearing portions 17 and 19, it is important to center the stirring shaft 11 with respect to the cooking pot 1. By this centering, the scraping blade 15 shown in FIG. 1 can be accurately aligned with the spherical surface of the bottom portion 3, and the bottom portion 3 can be effectively scraped and slid.

  In the present embodiment, the stirring shaft 11 is centered with reference to the first bearing portion 17. The bearing socket 45 of the second bearing portion 19 is welded to the mounting panel 43.

  First, the female bearing metal 29 of the stirring shaft 11 is abutted against the male bearing metal 31 of the first bearing portion 17 fixed to the bottom portion 3 and is spherically supported.

  The bearing socket 45 is disposed on the mounting panel 43, and the angle and the position are aligned with the stirring shaft 11 by using the jig 85. The mounting panel 43 can be moved relative to the mounting seat 47 within the range of the mounting hole 43a that is larger than the diameter of the fastening bolt at the time of this angle and positioning, and fine adjustment can be accommodated.

  When the positioning is completed, the mounting panel 43 is fastened and fixed to the mounting seat 47 with fastening bolts, and the bearing socket 45 is welded to the mounting panel 43 together.

  The positional shift of the bearing socket 45 due to the distortion caused by the current welding can be dealt with by finely adjusting the fastening position of the mounting panel 43 with respect to the mounting seat 47 again.

  Next, the seal 57 and the like are assembled, the movable flange 73 and the output flange 69 are coupled, and the motor frame 25 is assembled.

[Action]
The agitation cooking apparatus of the present embodiment can be applied to agitation cooking such as boiled sardines, various kneaded rice cakes, crushed rice cakes, custard cream, jam, jelly and the like.

  In such heat-stir cooking such as simmering and various kneaded rice cakes, when the ingredients are put into the cooking pot 1 and the stirring shaft 11 is rotated by driving the stirring motor 23, the scraping blades around the stirring shaft 11. 15 rotates, and the scraping blade 15 scrapes and slides on the inner surface of the bottom 3. Along with the rotation of the stirring shaft 11, steam is supplied to the steam jacket 7, and the ingredients in the cooking pot 1 are heated and stirred and cooked.

  At this time, the first bearing portion 17 is located in the foodstuff, but the second bearing portion 19 side is mainly located above the upper surface of the foodstuff. Thus, since the second bearing portion 19 is mainly located outside the food material, the seal 57 does not need to function substantially, and the food material does not enter and become clogged on the second bearing portion 19 side. However, in the unlikely event that foodstuff enters the second bearing portion 19 side, the seal 57 functions.

  And when foodstuffs are clogged in the 2nd bearing part 19 side, steam piping is appropriately connected to piping 63, and steam is pumped into steam hole 65 by pumping steam, and by steam of bearing metal 49 and seal 57 Cleaning can be performed easily.

  Further, on the first bearing portion 17 side, since the stirring shaft 11 is supported by the fitting of the male bearing metal 31 and the female bearing metal 29, a shaft seal portion or the like is not necessary, and the intrusion and clogging of foodstuffs are required. There is almost no confusion. In addition, since the male bearing metal 31 tends to be upward, the entering food tends to be naturally discharged between the male bearing metal 31 and the female bearing metal 29, and from this point, clogging can be suppressed. it can.

  When cleaning the first bearing portion 17 side, when the butterfly bolt 39 is screwed off and the bearing seat 35 is pulled out, the male bearing metal 31 is removed together and the female bearing metal 29 is exposed.

  Therefore, the male and female bearing metals 29 and 31 can be easily cleaned.

  For this reason, the number of times of cleaning can be greatly reduced as a whole, and the cleaning operation can be performed very easily, and maintenance for cleaning becomes extremely easy and can be simplified.

  In the cooking pot 1, when various kinds of koji, jelly, custard cream, boiled simmered food, etc. are heated and stirred, the inclination angle of the stirring shaft 11 is set to θ = 15 ° to 45 °, preferably 35 °. . The vertical stirring effect of the scraping blade 15 is not different from that of the horizontal axis. In addition, the slight tilting adds the left and right movements of the food material in the axial direction, resulting in a larger stirring effect. Therefore, the scraping blade 15 can be scraped off to obtain a hand-turning effect, and can be stirred and cooked without damaging delicate products such as highly viscous foods and granules. Furthermore, it can be used for hard foods and prepared foods that are particular about shape retention.

  When the stirring shaft 11 is thermally expanded during cooking and extends in the axial direction, the movable flange 73 moves against the urging force of the spring 75 toward the output flange 69 in the range of the interval S and can absorb the extension.

  Therefore, an excessive force does not act on the stirring shaft 11, and the scraping sliding by the scraping blade 15 can be accurately maintained.
