[Stirring cooking]
With the rotation of the agitation drive shaft 9 and the revolution of the agitation drive shaft 9 and the outer peripheral revolution shaft 31, ingredients such as fried noodles can be heated and stirred in the flat pot 3. Yakisoba is an example, and other ingredients can also be cooked with heating and stirring.

  The inner surface of the bottom 3b of the flat hook 3 is subjected to a scraping motion by a scraping blade 11 that rotates and revolves. The corners and side surfaces of the inner surface of the bottom 3b are scraped by the revolving side blades 33. By these two blades, the entire bottom portion 3b is scraped, and the food is prevented from being burnt.

  When the food on the bottom 3b is scraped by the scraping blade, it receives a scooping force in such a direction as to ride on the inclination of the outer blade 21 and the inner blade 23 of the scraping blade 11.

  The noodles that move so as to ride on the inclination of the scraping blade 11 can smoothly move over the arcuate surface portions 19a and 19b of the mounting plate 19 on the stirring drive shaft 9 side.

  Since the scraping blade 11 and the side blade 33 rotate relative to each other between the agitation drive shaft 9 and the outer periphery revolution shaft 31 (side blades 33) rotating and revolving, the stirring drive shaft 9 (scraping blade 11) and the outer periphery revolution shaft 31 ( The noodles present between the side blades 33) are scraped off and rearranged over the entire bottom 3b. While applying the external force to the lump on the hard surface, it can be heated from the surface of the pan that is in contact with the blade for a certain period of time until it comes into contact with the blade again, and the noodle is gradually heated and unburned. You can go.

  Most of the noodles on the pan move with the blades in contact with the scraping blades 21 or 23 at the bottom of the stirring blade that rotates and revolves. The noodles accumulated in the movement direction of the blades move in the outer circumferential direction, the inner direction, and the direction over the blades, and are distributed almost uniformly over the entire pan surface. The noodles on the pan surface remain in that position until they again come into contact with the scraping blade and are heated from the pan surface. In this way, the noodles are effectively heated for a certain period of time from the entire pan surface, so that the noodles can be effectively heated without being burnt, and the breakage of the noodles can be accelerated as the temperature increases.

  By adding the seasoning liquid, it is possible to cook noodles at a high temperature (over 80 ° C) with a sense of fried food.

[Function when fried noodles]
Next, fried noodle cooking using the heating and stirring apparatus 1 will be described. In addition, the cooking method of yakisoba is an example, and is not specifically limited.

  Noodles are usually refrigerated and stored in a certain quantity as a lump. When cooking in a flat kettle 3 that is a heating and stirring pot, the noodles are stirred as a large lump while the temperature is low, and heat transfer is performed at the bottom 3b and the like. Occurs only at the point of contact with the surface. As the temperature rises, the noodles become flexible and the noodles break up and can be mixed.

  The cooking procedure of noodles performed in the reference example of the present invention is as follows.

  (1) Ignite the gas heating device.

  (2) Add oil when the wall surface of the kettle reaches 150 ° C.

  (3) When the wall surface of the flat kettle reaches 200 ° C., the noodles are charged, the stirring drive shaft 9 is rotationally driven at 27 r / min, and the heating and stirring is continued for 2 minutes and 30 seconds.

  (4) Next, the fire is extinguished, and the stirring drive shaft 9 is rotationally driven at 27 r / min, and stirring is continued for 2 minutes and 30 seconds.

  (5) The stirring drive shaft 9 is rotationally driven at 35 r / min, and the seasoning liquid is charged into the flat kettle (split by hand) for about 1 minute.

  (6) The rotational speed of the stirring drive shaft 9 is reduced to 27 r / min, and the rotational drive is continued for about 1 minute.

(7) The stirring drive shaft 9 is continuously rotated at 27 r / min, cooling mist is sprayed for 30 seconds, and the kettle is cooled from the bottom. (The wall temperature of the kettle is lowered to a temperature at which scorching does not occur even when scraping stirring is stopped.)
(8) Bounce the stirring blade and drop the noodle on the blade.

(9) End the mist and tilt the hook. (In (7), the cooling of the pot by mist spray is started and the rotation of the blade is stopped after 30 seconds, but the mist cooling of the hook is continued and the cooling is stopped at this point.)
(10) Remove the noodles finished by tilting the pot.

  (11) Wash the kettle (with hot water).

  That is, the flat pot 3 is first heated, and oil is added when the wall temperature reaches 150 ° C. From the viewpoint of suppressing scorching, the wall temperature of the kettle when fried noodles is 130-230 ° C, preferably 150-210 ° C.

  Continue heating and when the wall temperature reaches 200 ° C, add all the noodles (40kg in a 1200φ pan). Stir the noodles with heat. As the noodles are mixed in large blocks, they come into contact with the hot pot wall and gradually become softer and gradually unravel. Although the gas heating is stopped, the heating of the noodles is continued by the heat accumulation in the flat pot 3.

  As described above, the noodles are loosened and mixed in such a manner that the noodles do not circulate with the blades but spread over the entire pan surface.

  More detailed description is as follows.

  The noodles of low temperature (about 10 ° C.) thrown into the flat pot 3 come into contact with the front surfaces of the outer blade 21 and the inner blade 23 of the scraping blade 11 that rotates and revolves. Then, while being heated at the bottom 3b of the flat hook 3, the inner face of the hook slides and moves with the scraping blades 11 and the like.

  Initially, the noodles are low in temperature and poor in flexibility, and receive an external force at a portion in contact with the flat pot 3 or a portion in contact with the scraping blades 11 and the like, and behave as one lump while slightly deforming. In this way, noodle chunks accumulate on the front surfaces of the outer blade 21 and the inner blade 23 of the scraping blade 11.

  The noodles accumulated on the rotating front surface of the outer blade 21 and the inner blade 23 of the scraping blade 11 that rotates and revolves in three directions: the outer peripheral side direction of the flat pot 3, the center side direction, and the direction over the scraping blade 11. Move to. The noodles that have moved over the outer blade 21 and the inner blade 23 of the scraping blade 11 come into contact with the auxiliary blades 25 and 27, and the noodles are pulled in the direction of rotation by the relative movement between the hook surface and the auxiliary blades 25 and 27. It becomes straight and mixing of the noodles proceeds.

  The noodles that have moved from the front surface of the outer blade 21 and the inner blade 23 of the scraping blade 11 that rotates and revolves toward the outer peripheral side of the flat hook 3 have the scraping blade 11 having a rotation speed faster than the revolution speed of the side blade 33. Rotation precedes 3 and the noodles in this part are dragged, and the loosening of the lump is promoted.

  In the case of hypocycloids, the rotation direction of the scraping blade 11 is opposite to the revolution direction of the side blades 33, so the mixing force is strong, and depending on the conditions such as noodles, the epicycloid and hypocycloid rotation type can be changed. Will choose.

  The noodles that have moved to the center side of the flat hook 3 are captured by the scraping blades 11 that rotate and revolve, and gather again on the front surfaces of the outer blades 21 and the inner blades 23 of the scraping blades 11.

  By repeating such movement, the noodle mass is heated and gradually unraveled.

  Most of the noodles on the pan move with the blades in contact with the scraping blades 21 or 23 at the bottom of the stirring blade that rotates and revolves. The noodles accumulated in the movement direction of the blades move in the outer circumferential direction, the inner direction, and the direction over the blades, and are distributed almost uniformly over the entire pan surface. The noodles on the pan surface remain in that position until they again come into contact with the scraping blade and are heated from the pan surface. In this way, the noodles are effectively heated for a certain time from the whole pan surface, and the pan surface is scraped completely and periodically, so that the noodles are effectively heated without scorching, and the noodles are released as the temperature rises. Can be accelerated.

  When the noodles are released to a certain extent and the noodles have a fried feeling, the next time the seasoning liquid is added, the seasoning liquid comes into contact with the hot pot 3 and boils. The generated steam comes into contact with the noodles and condenses. In this way, the temperature of the noodle is further increased and the surface is moistened, so that the fluidity of the noodle is improved, the mixing is rapidly improved and the temperature of the noodle is increased.

  Furthermore, in order to accelerate mixing, the stirring speed is increased. Since the noodles are slippery, the noodles never break.

  Reduce the rotation and continue cooking for about 1 minute.

  Mist is sprayed on the bottom 3b of the flat pot 3 to cool it, and the temperature of the flat pot 3 is lowered to around 100 ° C.

  When seasoning liquid is added, it becomes easy to burn, and when stirring / scraping is stopped at a pot temperature of 110 ° C. or higher, burning occurs.

The cooking is finished, the stirring drive is stopped, and the drive box 17 is raised. At this time, the noodles attached to the blades are collected in a pan. (Manual work)
Finish the mist cooling, tilt the pan and take out the cooked food (noodle). A noodle with a fried feeling was obtained at an average temperature of 86 ° C.

  In this way, there are also effects such as prevention of scorching on the pan surface and wall surface, prevention of entanglement on the stirring shaft, efficient heating by uniform distribution of ingredients on the pan surface, by selecting heating conditions and cooking conditions It can be made into noodles with a fried feeling of 80 ° C. or higher. In addition, the food is not limited to long ones such as noodles, and other general foods can be used with the scraping blades 11 while cooking and heating the food with the scraping blades 11 so that the food is sufficiently distributed between the outer peripheral revolving unit 13. Stir and mix.

    That is, mixing of ingredients is good. Ingredients can be distributed almost uniformly on the inner surface of the flat pot 3, and can be heated more efficiently (in a shorter time) than when the material is unevenly distributed. By scraping the body 3a and the outer bottom 3b by the revolution scraping blade 11, a double-stage multi-stage biasing mechanism is used to complete the scraping of the rotation and revolution scraping blade 11 with a large number of rotations. In addition, the entire inner surface of the flat pot 3 can be scraped sufficiently. There are almost no poorly dispersed (overly small) portions of the food, and overheating can be prevented there, and the occurrence of scorching can be prevented.

  The rotating and revolving type scraper can prevent scorching by scraping, but if the hook has a large distortion, scoring becomes insufficient and scoring occurs. In addition, the ingredients are moved by the blades with the blades, but the ingredients cannot be evenly dispersed on the surface of the hook, and there are portions of the pot surface with less ingredients, and heating is not performed effectively. Therefore, in the first embodiment, a so-called two-stage joint spring mechanism is employed.

  The heating and stirring apparatus 1 according to the first embodiment schematically shown in FIGS. 9 and 10 includes only a two-stage joint spring mechanism. The two-stage joint spring mechanism includes a first joint portion 57 between the revolution shaft intermediate portion 31b and the revolution shaft tip portion 31c, and a second joint portion 59 between the revolution shaft tip portion 31c and the side blade mounting plate 55. The second joint portions 57 and 59 are provided with first and second coil springs 61 and 63, respectively, as first and second elastic bodies. The revolution shaft tip portion 31c is orthogonal to the revolution shaft intermediate portion 31b and extends toward the bottom portion 3b along the trunk portion 3a.

  Therefore, the first joint portion 57 elastically urges and moves the revolution shaft tip portion 31c side toward the inner wall surface of the body portion 3a with respect to the bearing tube portion 47 by the urging of the first coil spring 61. The side blade 33 side is pressed against the body 3a. By this pressing, the blade edge of the side blade 33 is brought into elastic contact with the inner wall surface of the flat portion 3 on the trunk portion 3a side. The second joint portion 59 elastically presses the side blade 33 side against the revolution shaft intermediate portion 31 b against the bottom portion 3 b by the bias of the second coil spring 63. By this pressing, the scraping edge portion of the side blade 33 is brought into elastic contact with the bottom portion 3b.

  As shown in FIGS. 11 and 12, the first joint portion 57 between the revolution shaft intermediate portion 31 b and the revolution shaft tip portion 31 c includes a first bracket portion 65. The first bracket portion 65 includes a base portion 67. The base 67 is fixed to the end of the revolution shaft intermediate portion 31b without any step on the outer surface by in-row formation. The base 67 is provided with a hole 69, and a first rotation support part 71 is provided in front of the hole 69. The axial center C1 of the hole 69 is set parallel to the axial center C2 of the revolution shaft intermediate part 31b.

The rotation center C3 of the first rotation part 75 with respect to the first rotation support part 71 is arranged with the axis C2 of the revolution shaft intermediate part 31b sandwiched with the axis C1 of the hole 69. The rotation center C3 of the first rotation part 75 is orthogonal to the axis C1 of the hole 69 and the axis C2 of the revolution shaft intermediate part 31b.

  The shaft 77 includes a lock portion 77a that can be rotated and fixed at the distal end, and a head portion 77b at the proximal end. The shaft 77 is attached by extending the lock portion 77a straight in the direction of the shaft 77. A shaft 77 obtained by extending the lock portion 77a straight is passed through the center hole of the first rotation support portion 71 and the first rotation portion 75 from the lock portion 77a side, and the head portion 77b is one outer surface of the first rotation support portion 71. The lock portion 77a is bent by rotation in a state where the lock portion 77 is engaged. By bending the lock portion 77a, the lock portion 77a is engaged with the other outer surface of the first rotation support portion 71 as shown in FIG. 12, and the shaft 77 is prevented from coming off. The lock position of the lock portion 77a is fixed by an appropriate means such as a frictional force or a split pin. By preventing the shaft 77 from coming off by the lock portion 77a, the first rotation portion 75 is rotatably supported by the first rotation support portion 71 with one touch.

  An elastic contact engaging portion 75 a is projected from the first rotating portion 75, and the first bullet 73 is elastically contacted with the elastic contact engaging portion 75 a by the bias of the first coil spring 61. The first rotating portion 75 is formed integrally with the revolution shaft tip portion 31c.

  In the revolution shaft tip 31c, the upper portion 79 and the lower portion 81 are integrally formed at a right angle, and when the shaft center of the upper portion 79 coincides with the shaft center C2 of the revolution shaft intermediate portion 31b, the shaft center of the lower portion 81 is flat. It forms along the inner wall surface of the barrel portion 3a of the hook 3 and is arranged so as to incline downward in the scraping movement direction of the rotating circle around the stirring drive shaft 9.

  As shown in FIG. 13, the second joint portion 59 between the revolution shaft tip portion 31 c and the side blade attachment plate 55 has the same configuration as the first joint portion 57.

The second bracket part 65 includes a base part 67, a hole part 69, and a second rotation support part 71. The second coil spring 63 and the second burette 73 are inserted into the hole 69.

  If the axis C4 of the hole 69 in the second joint 59, the axis C5 of the lower part 81 of the revolution shaft tip 31c, and the rotation center C6 of the rotation part 75, the axis C4 of the second joint 59 is the first. The axial center C1 of the joint portion 57, the coaxial core C5 corresponds to the coaxial core C2, and the rotational center C3 corresponds to the rotational center C6.

  As shown in FIG. 11, the rotation center C6 of the second joint portion 59 is inclined from the trunk portion 3a side to the inner diameter side of the bottom portion 3b so that the inner side is located slightly rearward in the rotation direction when viewed from above the flat hook 3. Has been.

  The shape of FIG. 13 is simple, and it is good in production, use and hygiene. Since the rotation center C6 and the like are inclined as described above, when the side blades 33 are adjusted in the direction of the bottom 3b, displacement occurs in the axial direction. Since this displacement is absorbed by the first joint portion 57, as a result, the same performance as when the rotation center C6 is placed horizontally on the bottom portion 3b of the flat hook 3 is obtained.

  The second rotating portion 75 is integrally provided on the side blade attachment plate 55 side, and the side blade 33 is attached to the side blade attachment plate 55.

  The blade edges of the side blades 33 are formed in accordance with the shape of the inner wall of the flat hook 3, and in this embodiment, the barrel 3a and the bottom at the corners having a rounded corner between the barrel 3a and the bottom 3b of the flat hook 3. It is in close contact over 3b and scrapes and slides.

  When the side blades 33 are scraped and slid, the first joint portion 57 is elastically contacted by the first coil spring 61 with the first burette 73 elastically contacting the elastic contact portion 75a. Rotate around the rotation center C3. By this rotation of the first rotating portion 75, the revolution shaft tip portion 31c moves relative to the revolution shaft intermediate portion 31b, and the side blade 33 is urged and moved outward in the radial direction of the flat hook 3. It is pressed to the part 3a side.

  At the same time, in the second joint part 59, the second burette 73 is elastically contacted with the elastic contact engaging part 75a by the urging of the second coil spring 63 to rotate the second rotating part 75 around the rotation center C6. By this rotation of the second rotating portion 75, the side blade attachment plate 55 rotates relative to the revolution shaft tip portion 31c, and the side blade 33 is urged and moved downward in the axial direction of the stirring drive shaft 9. It is pressed against the bottom 3b side.

  The side blades 33 are pressed against both the trunk portion 3a and the bottom portion 3b by the cooperation of the first and second joint portions 57 and 59, and the side blades 33 are reliably moved from the trunk portion 3a to the bottom portion 3b. The scraping and sliding can be performed.

  In particular, the flat hook 3 is basically molded with high accuracy, but the accuracy is also limited, and the roundness of the inner peripheral surface of the body portion 3a of the flat hook 3 is shifted with respect to the rotation of the side blades 33. Deviation with respect to the stirring main drive shaft 5 may be caused. Further, such a deviation may occur as an assembling error even if the accuracy of the flat hook 3 is high.

  Even if such a shift occurs, the blade edge of the side blade 33 is accurately brought into contact with the body portion 3a and the bottom portion 3b by self-aligning by the urging rotation by the cooperation of the first and second joint portions 57 and 59 as described above. Therefore, the inner wall surface of the flat hook 3 can be scraped off accurately by the side blades 33 of the outer periphery revolving part 13.

  The configuration in which the blade edge of the side blade 33 is brought into precise contact with the body portion 3a and the bottom portion 3b by self-aligning by the urging rotation by the cooperation of the first and second joint portions 57 and 59 is as follows. The present invention can be applied not only to the form of revolving in the hook 3 but also to the form of rotating.
