Description

  The present disclosure relates to a soup filtration device for filtering broth.

  Some soups, such as ramen, are made by boiling pork bones and chicken waste and filtering the boiled liquid, so-called broth, to remove impurities such as bone fragments and fibers.

  In this case, it is common to pour the broth into a soup strainer having a size similar to that of a one-handed pot, and then filter the broth through a filter having fine eyes. However, it is necessary to pour the broth little by little with the soup strainer, especially when making a high-viscosity soup, extruding with a spatula etc. so that the viscosity of the broth is high and clogging does not occur in the filter part Is also required, which takes time and effort.

  Therefore, a soup filtration device that automatically filters boiling broth has been proposed (see Patent Document 1). This soup filtration device produces a soup that removes impurities by filtering the broth while suppressing clogging of the filter portion by reciprocating circular movement of a container-like filter portion into which the broth is poured. Can be stored in

JP 2011-251273 A

  However, the above-described conventional soup filtration device merely shakes the filter portion by reciprocating circular motion, and does not filter the broth by applying pressure like an operation of pushing out with a spatula or the like. Therefore, the soup filtration device takes a long time to produce soup, and may remove many umami components that cannot be filtered as impurities.

  The present disclosure has been made in view of the above circumstances, and an object of the present disclosure is to provide a soup filtration device that can sufficiently remove umami components while reducing the time required for soup generation.

  In order to achieve the above-described object, the soup filtration device of the present disclosure has a base portion having a built-in drive unit, and is detachably attached to the base portion, and has a cylindrical shape in which an upper portion is opened and a bottom portion is closed. An outer cylindrical body having an outlet at the bottom, a cylindrical shape having an open top and a closed bottom for receiving boiling water, and a filter unit having fine meshes provided on a peripheral wall, and rotatable by the driving unit. And the inner cylinder housed in the outer cylinder, and fixed to the base portion and disposed inside the inner cylinder, and relatively rotated along the filter portion with the rotation of the inner cylinder. And a scraper for removing impurities deposited on the filter section.

  The soup filtration device of the present disclosure thus configured can sufficiently extract the umami component while shortening the time required for soup generation by filtering with centrifugal force due to the rotation of the inner cylinder.

  As shown in FIGS. 2, 4, 6, and 7, the inner cylindrical body 50 has a bottomed cylindrical shape in which an upper end (upper part) is opened and a lower end (bottom part) is closed. Is provided with a space around it. The inner cylindrical body 50 has a cylindrical body 51 and a net 52. The cylindrical body 51 has a cylindrical shape with an open upper end, and a peripheral wall 51 a is formed of a punching metal 53. The punching metal 53 is a plate member made of a metal or the like provided with a large number of holes formed by punching. In the first embodiment, holes having a diameter of about 3 mm are provided evenly in a predetermined manner in the metal plate. Have been.

  The main body 51 has an inner boss 54. The inner boss portion 54 is attached so as to penetrate a bottom portion 55 serving as a lower end of the small body portion 51 while being aligned with the center of the small body portion 51. As shown in FIG. 6, the inner boss portion 54 is formed by combining a support portion 56 located inside the small body main portion 51 and a connecting portion 57 located outside the small body main portion 51 with the bottom portion 55 interposed therebetween. Have been. The support portion 56 has a cylindrical shape that rises inward from the bottom portion 55, and has a support hole 58 having a circular cross-section that rotatably penetrates a support rod portion 74 of a scraper 70 described later at the center thereof. As shown in FIG. 7, the connecting portion 57 has a cylindrical shape projecting outward from the bottom 55, and the inside thereof has a square cross section that allows the fitting of the protruding end portion 34 having a square outer shape of the output shaft 32. Connection hole 59. The connecting portion 57 transmits the rotational force of the output shaft 32 to the cylindrical body 51 by fitting the protruding end portion 34 into the connecting hole 59 and connecting. The main body 51 is formed by connecting the protruding end 34 of the output shaft 32 to the connecting portion 57 inside the mounting tube 35 fitted in the outer boss 41 of the outer main body 40. It is provided concentrically with 40 and is rotatable inside. For this reason, the inner cylinder 50 and the outer cylinder 40 can be provided with good space efficiency.

  As shown in FIG. 4, the mesh portion 52 has a cylindrical shape that can be fitted over the entire inner peripheral surface of the peripheral wall 51 a of the cylindrical body 51, and a punching metal 53 (the hole thereof) that forms the peripheral wall 51 a. ) And finer eyes. In the first embodiment, the mesh portion 52 is formed of a metal mesh having a mesh indicating the number of holes per inch of 10 to 60. The mesh portion 52 may be formed into a cylindrical shape in advance, or may be formed into a cylindrical shape by rounding a band processed shape.

  The inner dimension body 50 is formed by fitting a net portion 52 over the entire circumference so as to cover the inner peripheral surface of the punching metal 53 (peripheral wall 51 a) of the dimension body main body portion 51. Relative rotation is prevented and it is integrally rotated. For this reason, the peripheral wall of the inner dimension body 50 is configured such that the mesh part 52 is fitted inside the punching metal 53, and functions as a filter part 61 for filtering the broth. The filter portion 61 can secure the fineness required for filtration with the mesh portion 52 while securing the strength when the broth is pressed by the punching metal 53, and can appropriately filter the broth with a simple configuration. it can. In addition, since the net portion 52 is merely fitted, the net portion 52 can be removed, so that cleaning and maintenance of the net portion 52 can be facilitated, and fineness can be adjusted according to the required filtering function. Can be changed. A scraper 70 is provided to prevent impurities from sticking and clogging the filter portion 61.

  As shown in FIGS. 4 and 6, the scraper 70 includes a main body 71 that is in contact with the net 52 of the filter 61, a fixing plate 72 to which it is exchangeably fixed, and an arm extending therefrom. 73 and a support bar 74 to which it is attached. In the first embodiment, the main body 71 is brought into contact with the net 52 with a frictional force smaller than the frictional force between the punched metal 53 (peripheral wall 51 a) and the net 52. In the scraper 70 according to the first embodiment, the main body 71 and the fixing plate 72 are provided in a pair on both sides of the support rod 74 by the arms 73 extending in the diametrical direction of the inner cylindrical body 50 (FIG. 4).

  The support bar 74 has a long bar shape and is provided along the center axis of the inner cylindrical body 50. In the first embodiment, the support rod portion 74 passes through the support hole 58 of the support portion 56 of the inner boss portion 54 of the inner body portion 51 of the inner body 50 and the connection rod 59 of the connection portion 57 of the inner boss portion 54. By passing through the through hole 33 of the fitted output shaft 32, the lower end protrudes below the drive unit 13 housed in the base 11. The support rod 74 can rotate with respect to the support hole 58 and the through hole 33. The lower end of the support rod 74 protruding downward from the drive unit 13 is attached to a rotation stop plate 75 fixed to the support plate 26 that supports the drive unit 13 inside the base unit 11. The rotation stop plate 75 prevents the support bar 74 from rotating together with the output shaft 32 even when the motor 31 is driven and the output shaft 32 rotates. The rotation stopper plate 75 allows the support rod portion 74 to be pulled out when necessary, and the support rod portion 74 is fixed, thereby preventing the rotation of the scraper 70 and preventing the scraper 70 from rotating. The scraper 70 can be pulled out. In the first embodiment, the rotation stop plate 75 is rotated by fitting the lower end of the support rod portion 74 having a cross-sectional shape that matches the long hole 75 a provided in the rotation stop plate 75. , And the support rod portion 74 can be pulled out.

  As shown in FIGS. 1, 2, and 4, an open end 40a of the outer cylindrical body 40 is provided with a cylindrical cover 80 covering the open end 40a. The small body lid 80 has a disk shape, and is configured by providing a wire netting portion 82 on an annular frame portion 81. The annular frame portion 81 has an annular shape that can be placed on the open end 40 a, and has an inner diameter approximately equal to the diameter of the inner cylindrical body 50. The wire netting 82 is a net member that can cover the inside of the annular frame 81 and has a large mesh. The wire mesh portion 82 may have an eye size enough to remove large bone fragments and the like in the broth, and basically does not have a filtering function from the viewpoint of producing soup. The small body lid 80 constitutes a liquid inlet for injecting the broth into the inner body 50 in the filtering mechanism 12. At this liquid inlet, since the inner diameter of the annular frame portion 81 of the inner cylinder 50 is substantially equal to the inner diameter of the inner cylinder 50, the inner side of the outer cylinder 40 can be moved inward without checking the position of the open end of the inner cylinder 50. Then, the broth can be poured into the inner cylinder 50.

  Here, in the soup filtration device 10, the inner cylindrical body 50 is fixed to the output shaft 32 of the drive unit 13 provided on the base 11 through the outer boss 41, and the scraper is fixed to the base 11 through the through hole 33 of the output shaft 32. 70 is fixed. For this reason, by collecting the structure for attaching the outer outer cylinder 40, the inner inner cylinder 50, and the scraper 70 to the base portion 11 at the bottom 45 of the outer outer cylinder 40, some upper end side of the outer outer cylinder 40 and the inner outer cylinder 50 is opened. The structure can not be located. This makes it possible to increase the liquid inlet for pouring the broth into the inner cylinder 50, and to easily add the broth to the inner cylinder 50 that is rotating and filtering inside the outer cylinder 40. it can.

  The operation unit 14 has a changeover switch 36 for performing an operation of switching between driving and stopping the drive unit 13, and a volume 37 for adjusting the rotation speed of the motor 31 by a rotation operation. The drive mechanism 13 is appropriately driven in accordance with the operation of the operation section 14, whereby the filtration mechanism section 12 is driven.

  Next, a method of using the soup filtration device 10 according to the first embodiment will be described. First, the changeover switch 36 of the operation unit 14 is operated to rotate the inner cylinder 50, and the broth is poured into the inner cylinder 50 from the wire netting 82 of the cylinder lid 80 serving as a liquid inlet. Then, as the inner cylinder 50 rotates, the broth is pressed by the centrifugal force against the net portion 52 of the filter portion 61 on the peripheral wall while being stirred, and filtered. That is, the broth is filtered under pressure and flows out to the outer cylinder 40 as a soup from which impurities have been removed. The soup that has flowed into the outer cylindrical body 40 is taken out from an outlet 43 provided at the lowermost side of the bottom part 45, and is received by an unillustrated cylindrical body or the like placed below the bottom. Here, by operating the volume 37 of the operation unit 14 to adjust the rotation speed of the inner cylindrical body 50, it is possible to adjust the degree of the filtration pressure of the broth and to appropriately filter various kinds of broth. .

  In this process, there is a possibility that impurities such as bone fragments and fibrous material in the broth may stick to the net portion 52 and cause clogging. However, in the soup filtration device 10, the tip portions 71 a of the pair of main body portions 71 of the scraper 70 fixed to the support plate portion 26 of the base portion 11 come into contact with the mesh portion 52 of the filter portion 61, and Accordingly, impurities sticking to the net portion 52 are peeled off. Thereby, the soup filtration device 10 can filter soup and produce soup while preventing the filter unit 61 (the net portion 52 thereof) from being clogged. At this time, since the scraper 70 is fixed and the impurities are peeled off from the filter portion 61, the broth that rotates in the inner cylindrical body 50 can be stirred, and the broth can be more appropriately filtered and the soup can be filtered. Can be generated. In addition, since the inner cylinder 50 is inclined with respect to the horizontal plane, the rotating broth (especially its impurities) can be caused to fall by gravity due to gravity, and the stirring action in the inner cylinder 50 can be performed. Can be promoted, and the broth can be more appropriately filtered to form a soup.

  Here, since the scraper 70 is brought into contact with the net portion 52 with a frictional force smaller than the frictional force between the net portion 52 and the punching metal 53, the scraper 70 and the net portion 52 are deformed, for example, such that the net portion 52 is deformed. In the event that a problem occurs in which the frictional force increases with respect to, the mesh portion 52 can be rotated with respect to the punching metal 53 (the peripheral wall 51a). For this reason, even when the above-mentioned trouble occurs, it is possible to prevent an excessive load from being applied to the scraper 70, the structure for fixing the same, and the structure for rotating the inner dimension body 50, and the influence of the trouble can be minimized. . This is because, for example, when the mesh portion 52 is fixed to the punching metal 53, the scraper 70 tries to rotate together with the inner cylindrical body 50 when the above-described problem occurs.

  Further, in the soup filtration device 10, cleaning and maintenance can be performed after soup is generated. This is described below. First, it is confirmed that the operation is stopped by the changeover switch 36 of the operation unit 14, and then the small body lid 80 is removed from the outer small body 40. Next, the fixing of the lower end of the support rod portion 74 of the scraper 70 to the rotation stop plate 75 is released, the support rod portion 74 is pulled out from the rotation stop plate 75, and the support of the through hole 33 of the output shaft 32 and the inner boss portion 54. Withdrawing the support rod portion 74 upward from the support hole 58 of the portion 56, the scraper 70 is taken out from the inside of the inner cylindrical body 50. Next, the inner boss part 54 of the inner part body 50 is pulled out from the output shaft 32 (its protruding end part 34), the inner part body 50 is taken out from the inside of the outer part body 40, and the mesh part 52 of the filter part 61 is attached to the part body part. Remove from 51. Finally, the outer boss 41 is extracted from the mounting cylinder 35, and the outer cylindrical body 40 is removed from the base 11. Thus, the scraper 70, the main body 51 and the net 52 of the inner cylindrical body 50, and the outer cylindrical body 40 can be easily cleaned and maintained. The soup filtration device 10 can be assembled by performing the above operations in the reverse order.

  As described above, the soup filtration device 10 according to the first embodiment of the soup filtration device according to the present disclosure presses the boiled juice injected into the inner cylindrical body 50 against the filter portion 61 by centrifugal force and applies pressure to the filter so as to filter the soup. The impurities sticking to 61 are peeled off with a scraper 70. For this reason, the filter device 10 for soup can obtain the effect that a soup can be produced in which the umami component is sufficiently extracted efficiently in a short time without any trouble.

  Next, a soup filtration device 10A of Example 2 which is an embodiment of the present disclosure will be described with reference to FIGS. The soup filtration device 10A is an example in which some configurations are different from the soup filtration device 10 of the first embodiment. The soup filtration device 10A has the same basic concept, configuration, and effect as the soup filtration device 10 of the first embodiment, and thus the same reference numerals are given to the same components, and detailed description thereof will be omitted. The configuration of the soup filtration device 10A similar to that of the soup filtration device 10 is indicated by adding a letter A to the reference numeral, and different configurations will be described below.

  In the soup filtration device 10A of the second embodiment, as shown in FIG. 8, each fixed leg 25 is not provided on the base portion 11, and the base portion 11 is moved and fixed only by the four movable legs 24 with stoppers. Is switchable. The fixed legs 25 may be provided together, or the fixed legs 25 may not be provided in the soup filtration device 10 of the first embodiment.

  Further, in the soup filtration device 10A, as shown in FIG. 9, the inner cylindrical body 50A is formed only of the cylindrical body 51A. The basic configuration of the cylindrical body 51A is the same as that of the cylindrical body 51 of the first embodiment, except that the diameter of the hole provided in the punching metal 53A forming the peripheral wall 51a is reduced. different. For this reason, in the filter device 10A for soup, the filter part 61A is comprised by the peripheral wall 51a formed of the punching metal 53A, and cleaning and maintenance are easy.

  Here, in the soup filtration device 10A, fine powder having a size slightly smaller than the diameter of the hole can be filtered without passing the fine powder. Therefore, in the soup filtration device 10A, the fine particles equivalent to those obtained by manual filtration using a soup filtering device having a net whose hole size is smaller than the diameter of the hole of the punching metal 53A are obtained. It was possible to obtain a soup that had been filtered to a powder. The soup filtration device 10A presses the boiled juice against the filter portion 61A with centrifugal force by the rotation of the inner cylindrical body 50A, and applies pressure to filter. Therefore, when extruding by hand, even small fine powder is extruded from the hole, but in the case of centrifugal force, extrusion of the fine powder is restricted, so that the above-described effect can be obtained.

  As shown in FIG. 10, the cylindrical body 51 </ b> A has a cylindrical rotary support so as to fill a gap between the support rod portion 74 of the scraper 70 </ b> A in the support hole 58 of the support portion 56 of the inner boss portion 54 of the inner cylindrical body 50 </ b> A. A member 62 is provided. In the second embodiment, the rotation support member 62 is formed of polyacetal, and prevents the rotation of the support rod 74, that is, the scraper 70A, while smoothing the relative rotation with the support rod 74 made of a metal material. In the second embodiment, the same rotation support member 62 is provided at the upper end and the lower end of the through hole 33 of the output shaft 32, and the support rod 74 is supported at three points by the three rotation support members 62, so that the inner side is formed. The shake of the scraper 70A with respect to the small body 50A is prevented.

  In the soup filtration device 10 of the first embodiment, the lower two rotation supporting members 62 are provided in the same manner as in the second embodiment. As in the case of 2, the movement of the scraper 70 with respect to the inner cylinder 50 can be prevented. This is because in the soup filtration device 10 of the first embodiment, since both body portions 71 of the scraper 70 are in contact with the filter portion 61, the support rod portion 74 is substantially supported at three points.

  In the soup filtration device 10A, as shown in FIGS. 9 and 10, the scraper 70A includes a main body 71A, an arm 73, a support rod 74, and a knob 76. The main body 71A has a plate shape made of a metal material, and is directly fixed to both sides of the arm 73. The knob 76 is provided at the upper end of the support rod 74, is formed of a resin material that does not easily conduct heat, and has a disk shape having an outer diameter larger than that of the support rod 74.

  As shown in FIG. 11, the scraper 70A has both body portions 71A (tip portions 71a thereof) provided along the filter portion 61A with a slight distance D from the filter portion 61A. In the scraper 70A, a support rod portion 74 is supported by a rotation support member 62 provided in a support hole 58 of a support portion 56 serving as an upper end portion of the inner boss portion 54. Accordingly, the distance D between the main body 71A and the filter 61A can be maintained regardless of the rotation of the inner cylindrical body 50A.

  In the scraper 70A, both body portions 71A are formed of a metal material. For this reason, it is possible to prevent warpage, deformation, and further abrasion of the two main body portions 71A, maintain the distance D between the two main body portions 71A and the filter portion 61A, and eliminate exchange due to abrasion.

  In the soup filtration device 10A, as shown in FIG. 8 to FIG. 10, the tip of the outlet 43A of the outer cylindrical body 40 is cut off obliquely to regulate the flow of the soup when flowing out from the outlet 43A.

  In the soup filtration device 10A, a small body lid 80A that covers the open end 40a of the outside small body 40 is provided. The small body lid 80A includes an annular frame 83 supported by the open end 40a of the outer body 40, a cylindrical tubular part 84 protruding downward from the inner edge of the annular frame 83, and a filter for closing the lower end of the tubular part 84. It has a bottom net portion 85 provided with an eye larger than the portion 61A, and a pair of handle portions 86 provided on the annular frame portion 83.

  The annular frame portion 83 is an annular flange that can be placed on the open end 40a. The bottom net 85 is integrally formed of a metal plate member together with the annular frame 83, is provided with a plurality of holes, and has the same large size as the small body lid 80 (the wire net 82 thereof) of the first embodiment. . The handles 86 are arranged in pairs in the diameter direction of the annular frame 83 and are fixed to the annular frame 83.

  As shown in FIG. 10, the small frame lid 80A has an annular frame portion 83 placed on the open end 40a in a state where the cylindrical portion 84 is inserted inside the inside small cylinder 50A. The small body lid 80A is provided with a means for appropriately preventing a positional deviation from the outside small body 40. The small body lid 80 </ b> A forms a liquid inlet with a cylindrical portion 84 and a bottom net portion 85 extending from the inner edge of the annular frame portion 83. At this liquid inlet, since the cylindrical portion 84 is inserted inside the inner cylindrical body 50A, if the broth is poured into the inner cylindrical body 50A, the boiled liquid does not spill out of the inner cylindrical body 50A. It is surely put into 50A.

  The method of using the soup filtration device 10A of the second embodiment is the same as that of the soup filtration device 10 of the first embodiment, except that the liquid inlet for charging the broth is the cylindrical portion 84 of the small body lid 80A. Can be obtained. In the process, impurities such as bone fragments and fibrous material in the broth adhere to and accumulate on the filter portion 61A, causing clogging. In the soup filtration device 10A, a pair of main bodies 71A (tip portions 71a) of the scraper 70A fixed to the support plate 26 of the base 11 are spaced apart from the filter 61A by a distance D along the filter 61A. Rotate. Then, the main body 71A collides with the impurities deposited on the filter 61A, and peels off the deposited impurities from the filter 61A. In addition, the two main bodies 71A relatively rotate with respect to the filter section 61A, thereby moving the broth in the inner cylindrical body 50A relatively in the rotational direction along the surface of the filter section 61A, and impurities are transferred to the filter section 61A. Prevent sedimentation.

  In each embodiment, the outer body 40 is placed on both the support plates 22 and both support protrusions 23 of the inclined base part 11, but the outer body 40 can be attached to the base part 11 by being inclined with respect to the horizontal plane. It is not limited to the configuration of each embodiment. In addition, the outlets 43 and 43A are provided at the lowest position of the bottom part 45 due to the inclination of the outer body 40, but the soup flowing into the outer body 40 is taken out without leaving the outlets 43 and 43A. If possible, the outer cylinder 40 may not be inclined, and a structure for guiding the outlets 43 and 43A may be provided at the bottom 45 regardless of the inclination of the outer cylinder 40. It is not limited to.

  In the first embodiment, the mesh portion 52 is fitted into the punching metal 53 of the cylindrical body 51 to form the filter portion 61. However, a filter having a single structure (eg, as an example, a single structure) can be used as long as it filters the broth. 2) may be used, and the configuration is not limited to the configuration of the first embodiment. Further, in the filter portion 61, the relative rotational movement is prevented by the friction between the punching metal 53 and the mesh portion 52. However, the mesh portion 52 and the punching metal 53 may be fixed. Is not limited to this configuration.
