Description

  The present invention relates to a stirring device for mixing various ingredients such as paste, cream, jam, curry roux, sauce, soup, boiled food, and stir-fried food in the kettle, and in particular, in the process of stirring the ingredients in the kettle. When food materials adhere to the upper part of the inner side surface, the adhered food materials can be scraped mechanically and efficiently.

  Conventionally, as this kind of stirring device, for example, a stirrer described in Patent Document 1 is known. The stirrer of this document has a structure in which an inclined driven shaft (22) revolves around the main driving shaft (18) while rotating in association with the rotation of the main driving shaft (18).

  A stirring rod (not shown) is connected to the tip of the driven shaft (22) via a joint (25), and the stirring rod revolves around the driven shaft (18) integrally with the driven shaft (22). By rotating, the ingredients in the pot (20) are agitated.

  However, according to the conventional stirrer as disclosed in Patent Document 1, the food in the pot (20) is stirred with the stirring rod that revolves and rotates as described above. For this reason, for example, ingredients containing water (powdered koji, sugar and moisture in the case of kneaded koji) are put into the kettle (20) and heated with the heat of the kettle (20). In the case of stirring with a stirring rod, the introduced food material is pushed out and adhered to the upper side of the inner surface of the pot (20) by the rotation and revolution of the stirring bar, and the water in the attached food material evaporates. Since the food material is dried and sticks near the upper part of the inner side surface of (20), the operator must frequently perform the troublesome work of scraping it off with a spatula or the like, which is inconvenient.

  If the operator does not scrape the spatula with the spatula as described above, the dry and stuck food is burnt by the heat of the pot (20), and the burned food is heated by the revolving and rotation of the stirring rod (20 ) May be peeled off due to slight vibrations and mixed into the ingredients being stirred. In this case, the flavor and texture of the final product manufactured with the ingredients after stirring are changed by the burnt ingredients. It is easy for defective products to occur in the final product.

  In the above description, reference numerals in parentheses are those used in Patent Document 1.

  In the present invention, five blades may be provided radially at equal intervals around the contactor.

  In the present invention, when the main shaft starts to rotate, the driven shaft and the stirring rod rotate while revolving around the main shaft. At this time, the rotation of the driven shaft is a simple rotational motion that only rotates around its axis, but the rotation of the stirring rod is a conical motion inclined with respect to the vertical direction (a cone with a vertex on the driven shaft). The movement of the stirring rod and the abutment at the tip of the agitator moves up and down the inner surface of the hook while rotating and revolving. At this time, the blades on the outer periphery of the abutting element also move up and down integrally with the abutting element. This raising / lowering operation is periodically performed based on the period of revolution and rotation of the stirring rod. For this reason, the food material adhering to the vicinity of the turning point of the raising / lowering of the abutment, that is, the vicinity of the upper part of the inner side surface of the hook, is effectively scraped off by the blade as the blade rising to that vicinity functions as a spatula. For example, even if it cannot be scraped off at the nth raising / lowering cycle, it is scraped off at the subsequent raising / lowering cycle such as n + 1 or n + 2, etc. A troublesome conventional work of scraping can be omitted, and a stirring device capable of mechanically and efficiently scraping food adhering to the vicinity of the upper part of the inner side surface of the pot can be provided.

  Further, in the present invention, as described above, since the food adhering to the vicinity of the upper part of the inner side surface of the pot can be efficiently scraped, the food adhering to the burner is burnt or burnt by the heat of the pot. Spills off and mixes in the ingredients being stirred, and the flavor and texture of the final product manufactured with the ingredients after stirring is reduced due to burnt ingredients. Generation can be effectively prevented.

  Further, according to the present invention, the scraping operation by the blade is performed by the revolution and rotation of the stirring rod, and is performed in parallel with the stirring and kneading operation of the food by the revolution and rotation of the stirring rod. Therefore, it is not necessary to stop the revolution and rotation of the stirring rod during the scraping operation with the blade, so that the operating efficiency of the stirring device can be improved.

<Simple explanation of the pot>
As shown in FIG. 1, the stirring rod 7 is inserted into the pot 6 and food (not shown) is charged. The hook 6 has a double iron plate structure composed of two iron plates 6A and 6B, and steam from the steam supply pipe 19 is supplied to the gap between the iron plates 6A and 6B. It is comprised so that a foodstuff can be heated in the inside.

<Other configuration>
The stirring device M in FIG. 1 has a rotation direction changing means (not shown) in a control box CB provided with various operation buttons such as a device activation button. This rotation direction changing means switches the main shaft 9 from forward rotation (for example, clockwise) to reverse rotation (for example, counterclockwise) or from reverse rotation to forward rotation, thereby rotating and revolving the driven shaft 10 and the stirring rod 7. Can be changed from forward rotation to reverse rotation.

  In particular, in the agitator M of FIG. 1, as described above, the motor 8 is employed as the rotational drive source of the main drive shaft 9, and therefore the rotation direction changing means in the control box CB described above is the rotation of the motor 8. By changing the direction electrically, switching the rotation direction of the main drive shaft 9 from normal rotation to reverse rotation or reverse rotation to normal rotation, and thereby changing the rotation direction of the driven shaft 10 and the stirring rod 7 (forward Rotation to reverse rotation or reverse rotation to forward rotation).

  In the control box CB, in addition to the rotation direction changing means described above, the number of rotations of the main shaft 9 is set, the main shaft 9 is rotated at the set number of rotations, and the main shaft 9 is controlled by sequence control. Various control means relating to the rotation of the main drive shaft 9 are provided such that the forward rotation and the reverse rotation are repeatedly performed at predetermined intervals.

《Explanation of operation of stirring device》
Next, the operation of the stirring device M of FIG. 1 configured as described above will be described with reference to FIGS.

  In the case of producing a kneaded rice cake as an example of the foodstuff with the stirring device M of FIG. 1, the kettle 6 is heated with steam from the steam supply pipe 19, and powdery koji, sugar and moisture are put into the heated kettle 6. . Then, by operating the touch panel or the like of the control box CB, the motor 8 is activated and the main drive shaft 9 is rotated.

  When the main drive shaft 9 begins to rotate as described above, the driven shaft 10 and the stirring rod 7 (7A, 7B, 7C) rotate while revolving around the main drive shaft 9. At this time, the rotation of the driven shaft 10 is a simple rotational motion that only rotates around its axis, but the rotation of the stirring rod 7 becomes a conical motion inclined with respect to the vertical direction as described above. The stirring rod 7 and the contact 73 at the tip of the stirring rod 7 ascend and descend on the inner surface of the hook 6 as shown in FIG. 3 while rotating and revolving.

  As the stirring rod 7 moves up and down as described above, the distance from the tip of the stirring rod 7 to the inner bottom surface and the inner surface of the shuttle 6 changes according to the rotation angle of the stirring rod 7. Since this change in distance is absorbed by the expansion and contraction of the stirring rod 7, the contact 73 at the tip of the stirring rod 7 does not move away from the inner bottom surface or the inner side surface of the hook 6.

  By the way, also in the stirring apparatus M of FIG. 1, a part of the ingredients (a mixture of koji, sugar and moisture in this operation description) put into the pot 6 is partly caused by rotation and revolution of the stirring rods 7B and 7C. There is a possibility that the food P will dry and stick to the vicinity of the upper part of the inner side surface of the pot 6 by being pushed out and adhering in the upper direction and the moisture in the adhering food is evaporated. However, the food P adhering to the vicinity of the upper part of the inner side surface of the hook 6 is as follows by the blade 74 on the outer periphery of the contact 73 before the water evaporates (or even after the water evaporates). It is mechanically efficient and quickly scraped.

  As described above, when the stirring rod 7 and the contact 73 at the tip thereof rotate and revolve, the blade 74 on the outer periphery of the contact 73 is also integrated with the contact 73. Go up and down. This raising / lowering operation is periodically performed based on the period of revolution and rotation of the stirring rod 7. Therefore, the contact 73 is attached in the vicinity of the folding point RE of the lift (specifically, the point where the contact 73 has risen to the maximum inner surface of the hook 6), that is, in the vicinity of the upper portion of the inner surface of the hook 6. The food P is scraped off effectively by the blade 74 when the blade 74 that has risen to the vicinity functions as a spatula. In addition, even if the food P adhered in such a manner cannot be scraped off at the nth raising / lowering cycle, for example, it will be scraped off at the subsequent raising / lowering cycle such as n + 1 or n + 2, etc. According to the apparatus M, it is possible to mechanically and efficiently scrape the food P adhering to the vicinity of the upper part of the inner surface of the hook 6, and there is no possibility that the food stuck to the upper part of the inner surface of the pot 6 will remain. It is not necessary for the operator to scrape such food with a spatula or the like.

  Further, according to the stirring device M of FIG. 1, the blade 74 on the outer periphery of the contactor 73 as described above descends to the vicinity of the inner bottom surface of the hook 6 together with the contactor 73, so There is also an effect of stirring with the blade 74, and there is an advantage that the stirring effect of the food is improved.

  In the stirring device M of FIG. 1, as described above, the joint J that can adjust the inclination angle of each stirring bar 7 is employed. Therefore, in the joint J, for example, by adjusting the inclination angle of only the stirring bar 7A, Only the contact 73 at the tip of the stirring rod 7A can set the raising / lowering turning point RE high or low (adjustment of the turning point RE height).

  The present invention is not limited to the embodiments described above, and many modifications can be made by those having ordinary knowledge in the art within the technical idea of the present invention.

  For example, in the stirring device M of FIG. 1, as described above, among the three stirring rods 7 (7A, 7B, 7C), five blades 74 are attached to the contactor 73 at the tip of one stirring rod 7A. Although provided, the number of the stirring rods 7 can be increased or decreased as needed. The number of blades 7 may also be five or one, and the number can be appropriately increased or decreased as necessary. Furthermore, it is possible to provide the blade 74 not only with respect to one but also with a plurality of contact members at the tip of the stirring bar. In this case, the blades provided in the contact members approach each other. Design so as not to interfere too much.
