Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a vertical kneading device suitable for kneading wheat flour (including udon powder), other powdery substances, viscous materials, semi-kneaded substances or other inorganic materials and liquids, and in some cases liquids and liquids. Regarding

[0002]

[Prior art]

 A vertical drive shaft is housed in the center of a cylindrical container, and an agitator equipped with an impeller on the drive shaft is used when a liquid with a relatively low viscosity or a powder or the like is mixed into the liquid. It is used.

[0003]

[Problems to be solved by the device]

 However, when trying to knead materials with relatively high viscosity (such as wheat flour and water) with a conventional vertical stirring device, the raw material rotates only in the part where the stirring plate is in contact, and sufficient kneading is performed. There was a problem that was not obtained. Of course, if the rotation speed is slowed, the raw materials will flow in the container, and thus it is theoretically possible to knead, but there is a problem that the efficiency is poor. Further, when the stirring blade is rotated, a centrifugal force inevitably acts on the rotating raw material and adheres to the inner wall of the container, so that there is a problem that the stirring effect is poor. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a vertical kneading device that has good stirring efficiency and that can stir and knead even those with a relatively high viscosity.

[0004]

[Means for Solving the Problems]

 The vertical kneading device according to claim 1 which is in accordance with the above object, has a vertical stirring member provided with a stirring blade, a kneading container in which the stirring member is disposed, and a rotation driving source of the stirring member. In the vertical kneading device, the stirring member is provided with two driving shafts juxtaposed in parallel with each other, and the stirring blades are attached to the respective driving shafts out of phase with each other and have a cutting surface inclined downward toward the front. In addition, the kneading container is configured such that the stirring member has a bicircular cross section slightly larger than the outer rotation locus, and the rotation drive source is configured by rotating the stirring member in the same direction. .

[0005]

[Action]

 In the vertical kneading device according to claim 1, two agitating members are arranged in parallel, and these agitating members respectively rotate in the same direction in a kneading container having a bicircular cross section with a peripheral gap and a small gap. Because of the arrangement, the raw materials rotate not in one direction but in a bi-circular shape. Further, since each stirring blade has a cross section that is inclined downward toward the front, the raw material rotates in a bi-circular shape as described above, and is pushed up by the stirring blade, so vertical flow also occurs. As a result, all the raw materials are mixed almost evenly. Therefore, the stirring of the raw material is only required to be rotated at a low speed, and the amount of heat generated by this is also small. As a result, the quality of the raw material is not changed by heat, and the flavor does not fly when the raw material is food.

【Example】

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. FIG. 1 is a sectional view of a vertical kneading device according to an embodiment of the present invention, FIG. 2 is a partial sectional plan view of the same, and FIG. 3 is a perspective view of a stirring blade used in the same vertical kneading device.

As shown in FIGS. 1 to 3, a vertical kneading apparatus 10 according to an embodiment of the present invention includes a vertical kneading container 11 and stirring members 12, 13 housed in the kneading container 11. And a drive source 14 for these. These will be described in detail below.

The kneading vessel 11 is made of a stainless steel material and has a bi-circular shape according to the outer locus of the stirring members 12 and 13 inside, as shown in FIG. A bottom plate 14a is provided in the lower portion of the kneading container 11, an upper portion serves as a discharge inlet 15, and a lid 16 is covered during kneading.

The stirring members 12 and 13 are entirely made of stainless steel, and have drive shafts 17 and 18 and stirring blades 19 and 20 attached to the drive shafts 17 and 18 at predetermined intervals. Is configured. As shown in FIG. 3, the stirring blade 19 (same as 20) has a cross-section that is inclined in the traveling direction (direction of arrow A), that is, in the forward direction, and scoops up the raw material to be kneaded. At the same time, an arc-shaped vertical plate 19a is provided at the end thereof so as to scrape off the raw material adhering to the side wall of the kneading container 11. In addition, 19b shows a boss. Then, four agitating blades 19 and 20 are symmetrically attached to the drive shafts 17 and 18 by 90 degrees in phase with each other, and an eccentric load is applied to the drive shafts 17 and 18. The stirring blades 19 and 20 adjacent to each other are attached so that the phases thereof are vertically shifted with the exception of the lowermost object.

The drive shafts 17 and 18 are rotatably supported by bearings 21 and 22 provided on the bottom plate 14 a and bearings 24 and 25 attached to a pedestal 23, respectively. The sprockets 26 and 27 and the chain 28 are connected so as to rotate in the same direction. A sprocket 29 is provided below the drive shaft 17, and is connected to a sprocket 30 attached to the output shaft of the reduction drive motor constituting the drive source 14 by a chain 31 to rotate the drive source 14. By doing so, the drive shafts 17 and 18 rotate in the same direction.

The kneading container 11 is fixed to the pedestal 23, but when discharging the kneaded raw material, the whole kneading container 11 is tilted about a shaft 32 at the bottom. The rotation speed of the drive shafts 17 and 18 is 30 rpm in this embodiment, but can be selected in the range of 20 to 60 rpm depending on the raw material.

Next, a method of using the vertical kneading device 10 according to the above-described embodiment and its operation will be described. When a predetermined amount of flour and water, which is an example of raw materials, are added and a switch of the driving source 14 is inserted, The stirring members 12 and 13 rotate in the same direction. As a result, the raw material is scooped up by the stirring blades 19 and 20 and rotates in a bi-circular shape, so that the whole flour and water are sufficiently stirred, and further, the raw material attached to the side wall of the kneading container 11 Also, it is scraped off by the vertical plate 19a and sufficiently kneaded. After performing the kneading work for an appropriate time, the kneading container 11 is tilted to carry out the product. In the above-mentioned embodiment, all materials are made of stainless steel, but it is also possible to further coat the inside thereof with a fluororesin or other synthetic resin, which further improves the peelability of the raw material. Become. In the above-mentioned embodiment, the case where wheat flour and water are used as the raw materials has been described, but the present invention is naturally applicable to other raw materials. Further, in the above-mentioned embodiment, the kneaded product is discharged by tilting the whole vertical kneading device 10. However, the discharge port having the lid for opening and closing the bottom plate or the side plate close to the bottom plate. It is also possible to provide a product, which allows the product to be discharged without tilting.

[Effect of device]

 The vertical kneading apparatus according to claim 1 is provided with two stirring members, which are arranged so as to rotate in the same direction in a kneading container having a bicircular cross section having a small gap with the outer peripheral locus. Therefore, the raw material is not simply rotated in one direction but is rotated in a bi-circular shape, and each stirring blade has a cross section inclined downward toward the front. Since it is pushed up, a vertical flow is also generated, which causes all the raw materials to be mixed almost uniformly and efficiently. Therefore, the agitation of the raw material is only required to rotate at a low speed, and the amount of heat generated by this is also small.As a result, the quality of the raw material is not changed by heat, the flavor does not fly when the raw material is food, and the power loss is further reduced. Also few.
