Description

The present invention relates to a method and apparatus for removing powder dispersed on the surface of food. In detail, by contacting the rotating elastic plate with the upper surface of the belt-like food dough that is continuously conveyed, the powder spread on the upper surface of the food dough is paid and leveled and adhered to the entire surface. It relates to the device.

An apparatus for attaching powder to the entire surface of food is conventionally known. For example, Patent Document 1 discloses a technique in which food is deposited in a powder deposited on a conveyance path so that the powder adheres to the food surface. The apparatus of Patent Document 1 includes a plurality of rocking members that trace a top surface of the food material to attach a predetermined granular material to the food material top surface and remove excess powder.

Patent Document 2 discloses a technique for thinly attaching a powder to a food surface by rotating a rotary drum provided with a powder medium tape. In the apparatus of Patent Document 2, the powder adhering to the roller is included in contact with the powder medium tape, and the powder medium tape adheres to the food by touching the food.

Patent Document 3 discloses a technique for sweeping powder from the surface of food dough with a rotating brush roll. In the apparatus of Patent Document 3, a brush roll that is rotatable so as to be in sliding contact with the upper surface of the food dough is provided. This brush roll has a structure in which nylon bristles are planted on a roll shaft. In addition, the powder that has been spread on the upper surface of the strip-shaped food dough in advance by the powder supply mechanism adheres to the entire surface of the food dough by being swept away by the movement of the rotating brush bent and returned.

Registered Utility Model No. 3090548 Japanese Patent Laid-Open No. 62-259536 Japanese Utility Model Publication No. 51-34599

In the apparatus disclosed in Patent Document 1, since the food is hidden while the powder is preliminarily deposited, the food may stay in the powder and the conveyance may be delayed. In addition, foreign substances such as dough are easily mixed in the deposited powder, and the mixed foreign substances are difficult to find. In addition, during production, it is necessary to always deposit a powder enough to envelop the whole food, so that more powder than the amount actually attached to the food is required, which is not preferable from the viewpoint of economic efficiency.

Although the apparatus disclosed in Patent Document 2 partially solves the problem of foreign matter contamination and economy as described above, problems still remain. In the apparatus of Patent Document 2, the amount of powder adhering to food is affected by the amount of powder held on the powder medium tape, but the powder medium tape is rotating, so the powder is held constant. Therefore, it is difficult to adjust the amount of powder attached to food. In addition, the powder media tape is attached to the rotating drum with a stainless steel wire, but since the powder is supplied from above the attachment portion, the powder accumulates in the attachment portion, becomes a lump, and drops onto the food. There is a possibility of causing a food product defect.

The apparatus disclosed in Patent Document 3 discloses a technique in which a necessary amount of powder is spread on a food dough in advance and the powder is swept using a rotating brush. Although this technique solves the problem of the amount of powder adhering to the food dough, it requires much time for hygiene management and maintenance inspection. This is because the powder accumulated in the gap between the rotating brushes, the dough, or the hair of the brush falling off the rotating brush itself can cause contamination. Moreover, the apparatus of patent document 3 has the subject that it is difficult to respond to the change of the height and thickness of food dough. This is because, in particular, the tip of the rotating brush needs to be in contact with the powder in order for the powder to adhere to the entire surface of the food dough. When the height and thickness of the food dough are increased, the rotating brush comes into contact with the dough at a portion closer to the root, not at the tip (the outer peripheral portion of the rotating brush). The closer to the root of the brush, the less the bending of the brush, and it becomes impossible to effectively sweep the powder, and the powder tends to accumulate in the gaps between the hairs.

The present invention aims to solve the above-mentioned problems. The present invention relates to a dusting method for removing powder adhering to the surface of a food dough conveyed in the conveying direction by a conveying means, and an outer end of an elastic plate that moves relative to the food dough being conveyed A plurality of spatula-like portions formed by providing a plurality of slits on the edge are curved and brought into contact with the surface of the food dough by elastic deformation, whereby powder on the surface of the food dough is removed.

Embodiments of a dusting device according to the present invention will be described below with reference to the drawings. In addition, this invention is not limited by these Examples.

A first embodiment of the present invention will be described with reference to FIGS. The powder wiping device 1 is a device that adheres the powder 11 to the food dough 10. Examples of the food dough 10 in the present invention include, but are not limited to, bread dough, pastry dough, cookie dough, mashed potato dough, and the like that are extended into a sheet and continuously conveyed. Examples of the powder 11 include wheat flour, sugar, bread crumbs, almond poodles, corn grits, and the like. The powder 11 is appropriately used depending on the product to be produced.

The powder wiping device 1 includes a conveying means 2 that conveys the food dough 10 in the conveying direction A, a powder spreading device 3 provided above the conveying means 2, and a powder spreading device 3 above the conveying means 2. And a dusting mechanism 4 that is rotatably provided downstream in the conveyance direction and rotates in the rotation direction R. In this embodiment, the conveying means 2 is a belt conveyor using an endless belt, and since a known device is used, details are omitted. The powder spraying device 3 may be any device, and since a known device is used in this embodiment, the details are omitted. For example, the powder 11 is stored in the hopper and provided at the bottom of the hopper. An example is one in which the powder 11 is dropped and supplied from the mesh-shaped opening.

The food dough 10 is supplied from the right hand in FIG. 2 to the conveying means 2 of the dusting device 1 by an arbitrary means (not shown). The supplied food dough 10 is transported in the transport direction A, and the above-described powder spraying device 3 sprays the powder 11 on the upper surface of the food dough 10. The powder sprayed from the mesh-shaped opening can be spotted on the dough, or in places where it is not sprayed. The food dough 10 on which the powder 11 has been sprayed is further conveyed below the powder wiping mechanism 4.

The dusting mechanism 4 is horizontally provided with a rotation shaft 41 in a direction intersecting the conveyance direction A of the conveyance means 2, and the rotation shaft 41 has a plate clamping portion 42 in the circumferential direction thereof. In the present embodiment, five plate clamping portions 42 are provided at equal intervals in the circumferential direction, but this number may be determined as appropriate, and the present invention is not limited by this embodiment. Each of the plate holding portions 42 holds the elastic plate 43 in the width direction. In this embodiment, the length of the elastic plate 43 in the width direction is 210 mm, and the length in the height direction perpendicular to the width direction is 90 mm. In addition, a polyurethane food belt material made of polyurethane having a thickness of 0.7 mm is used as the material of the elastic plate 43, but this material may be selected as appropriate, for example, other chemically synthesized elastic material. Materials and canvas can also be used.

The elastic plate 43 has the spatula-like portion 45 by providing a plurality of slits 44 at the outer peripheral edge of the elastic plate. In this embodiment, the depth of the slit 44, that is, the length in the radial direction is set to 20 mm to 50 mm, and the interval between the slits 44 is set to 4 mm to 12 mm. When the material of the elastic plate 43 in the present embodiment is used, the elasticity of the spatula 45 is optimized by determining the length and interval of the slit 44 within the range of this dimension, so that the food dough 10 You can pay the powder without damaging it. However, the dimensions of the spatula portion 45 should be adjusted as appropriate according to the elasticity of the material of the elastic plate 42. In addition, by using a belt material having fine irregularities on the surface as the material of the elastic plate 43, it is possible to improve the powder holding force of the spatula portion 45.

The dust removal mechanism 4 controls the rotation shaft 41 linked to a control motor (not shown) so that the elastic plate 43 faces the conveying direction A on the contact surface with the food dough 10. (See arrow R in FIGS. 1 and 2). Accordingly, the spatula-shaped portion 44 of the elastic plate 43 contacts the food dough 10 from obliquely above on the downstream side in the transport direction, and moves to the upstream side in the transport direction while keeping the contact as it is. It moves away diagonally upward on the upstream side in the transport direction. In this embodiment, the rotation speed of the rotating shaft 41 is set between 13 rpm and 20 rpm. This is because if the lower limit value of the speed is not reached, the powder 11 can be dispensed to the food dough 10, and if the upper limit value is exceeded, the powder 11 is scattered by the spatula portion 44 and the working environment is deteriorated. Further, by adjusting the rotation speed of the rotary shaft 41, the plurality of elastic plates 43 can pass through the same location on the food dough 10, so that the amount of the powder 11 attached on the food dough 10 Can be adjusted. However, these speed ranges depend on the conveyance speed of the food dough 10, and should be set as appropriate.

The spatula-like portion 45 pays off the powder 11 dispersed on the upper surface of the food dough 10 so as to be adhered to the entire surface of the food dough 10. That is, when the spatula-shaped portion 45 comes into contact with the food dough 10, it spreads a portion that is a waste of the powder 11, and the portion on the dough 10 where the powder 11 is not spread. Powder 11 is adhered. At this time, the spatula-shaped portion 45 is bent by the resistance of the food dough 10, and the powder 11 is dammed by the bent portion, and the powder 11 is leveled with respect to the food dough 10 in the width direction.

Since the spatula-like portion 45 is provided with slits 44 in the elastic plate 43, the spatula-like portion 45 is not missing from the elastic plate 43, and the powder 13 is leveled like a conventional rotary brush. It is possible to reduce the possibility of contamination by foreign matter derived from the member itself. In addition, the dough and powder are relatively less likely to stick, and the possibility of foreign matter contamination can be reduced. Further, since the spatula-like portion 45 dissipates the powder 11 by sliding relative to the food dough 10, the height position of the curved portion of the spatula-like portion 45 due to a change in the thickness of the dough 10 is affected. It is possible to obtain a certain effect without receiving it. In addition, by providing a plurality of spatula-like portions 45, it is possible to cope with changes in the unevenness of the surface of the food dough 10. In addition, as described above, the spatula-shaped portion 45 disperses the powder while smoothing the curved portion thereof, so that even with a relatively small amount of the powder 11, the powder 11 is efficiently attached to the food dough 10 over the entire surface. It is possible to make it.

The description of the conveying apparatus according to the first embodiment of the present invention is generally as described above. However, the present invention is not limited to this, and various modifications can be made within the scope of the claims. For example, in the present embodiment, the dusting mechanism 4 includes five elastic plates 43, but it is also possible to provide a larger number. In this case, when the food dough 10 passes under the powdering mechanism 4, it is possible to level the same portion a plurality of times, which is effective when it is necessary to level a relatively large amount of powder 11. . Further, the rotary shaft 41 may be a shaft having a polygonal cross section, and the elastic plate 43 may be fixed to each side of the shaft with a screw or the like. In this case, since the configuration is simpler, maintenance inspection and the like are easier.

Further, the spatula portions 45 of the elastic plates 43 may be configured not to overlap each other. For example, the elastic plate having a length in the width direction of 210 mm and slits 44 provided at intervals of 5 mm from the side end, and a length in the width direction of 205 mm from the side end. Two types of elastic plates having slits 44 provided at intervals of 5 mm are prepared, and are sandwiched alternately between the plate sandwiching portions 42. In this configuration, even when the powder 11 leaks from the gap between the spatula portions 45 of an elastic plate and becomes linear on the food dough 10, the spatula portion 45 of the next elastic plate It is possible to pay off.

Further, when the sheet-shaped dough food 10 is continuously supplied, when the leading end of the sheet of the dough food 10 passes below the powder removal mechanism 4, the rotation direction of the powder removal mechanism 4 is set, and the elastic plate 43 is the food. You may provide so that it may move to the same direction as the conveyance direction of the said food dough 10 in a contact surface with the dough 10 (clockwise in FIG. 1). In this case, it can prevent that the front-end | tip part of the sheet | seat of the dough food 10 rolls up by the powder removal mechanism 4. FIG. After the front end portion of the sheet passes below the powdering mechanism 4, the rotation direction of the powdering mechanism 4 is changed to the reverse direction (counterclockwise in FIG. 1).

Next, a second embodiment of the present invention will be described with reference to FIG. The 2nd Example in this invention is the structure which changed the track | orbit of the elastic body plate 43 of the powder wiping apparatus 1 with respect to the 1st Example. Constituent elements similar to those of the rounding forming apparatus 1 of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

The powder wiping device 1 includes a conveying means 2 that conveys the food dough 10 in the conveying direction A, a powder spreading device 3 provided above the conveying means 2, and a powder spreading device 3 above the conveying means 2. Is provided with a dusting mechanism 5 downstream in the conveying direction. The food dough 10 is supplied from the right hand in FIG. 2 to the conveying means 2 of the dusting device 1 by an arbitrary means (not shown). The supplied food dough 10 is transported in the transport direction A, and the above-described powder spraying device 3 sprays the powder 11 on the upper surface of the food dough 10. The powder 11 sprayed from the mesh-shaped opening can be spotted in places where the powder is lumped or not sprayed. The food dough 10 on which the powder 11 has been sprayed is further conveyed below the powder wiping mechanism 5.

The powdering device 1 in the second embodiment has a configuration in which the powdering mechanism 4 is changed to a powdering machine 5. The dusting mechanism 5 is horizontally provided with rotating shafts 51A and 51B in a direction intersecting the conveying direction A of the conveying means 2, and an endless member 52 is wrapped around the rotating shafts 51A and 51B. The endless member 52 is provided with a plate clamping portion 53. In this embodiment, the endless member 52 uses a belt-like endless belt, and the plate clamping portion 53 is fixed to the endless belt with a fixing tool such as a screw. Furthermore, each of the plate clamping portions 53 clamps the elastic plate 54 in the width direction. In this embodiment, a polyurethane food belt material is used as the material of the elastic plate 54. The elastic plate 54 is provided with the spatula-like portion 56 by providing a plurality of slits 55 at the radial outer edge thereof.

The dust removal mechanism 5 rotates the endless member 52 by rotation of a rotating shaft 51A driven by a control motor (not shown). At this time, the movement trajectory of the elastic plate 54 has a transport direction component L that relatively moves in parallel with the transport direction by the transport means. The elastic body plate 54 is close to the conveying means 2 from above, is in contact with the food dough 10, and is kept in contact with the food dough 10 while being in the conveying direction A along the conveying direction component L. Translate a certain distance in the opposite direction and then move away from the food dough 10.

The spatula-like portion 56 of the elastic plate 54 disposes the powder 11 sprayed on the upper surface of the food dough 10 so that it is completely attached on the food dough 10. That is, when the spatula-shaped portion 56 comes into contact with the food dough 10, it spreads out the portions that are the lumps of the powder 11, and the portions on the dough 10 where the powder 11 is not spread. Powder 11 is adhered. At this time, the spatula-shaped portion 45 is bent by the resistance of the food dough 10, and the powder 11 is dammed by the bent portion, and the powder 11 is leveled with respect to the food dough 10 in the width direction.

In the second embodiment of the present invention, an effect equivalent to that of the first embodiment can be expected. That is, there is an advantage that it is easy to cope with a reduction in the possibility of foreign matter contamination, a change in the thickness of the food dough, and surface irregularities. In addition, since the spatula-like portion 56 has a longer relative sliding distance to the food dough 10 than the first embodiment, the above-described powder 11 is spread and damped to the food dough 10. It has a relatively high leveling effect on the entire surface. Since the food dough 10 is not easily damaged by increasing the rotational speed of the powder removal mechanism 5 depending on the relationship with the dough conveyance speed, adjustment of how many times the leveling operation is provided for the same portion of the surface of the food dough 10 is adjusted. Is wide.

The description of the transport apparatus according to the second embodiment of the present invention is generally as described above. However, the present invention is not limited to this, and various modifications can be made within the scope of the claims. For example, in this embodiment, six plate sandwiching portions 53 are provided at equal intervals in the circumferential direction, but this number may be determined as appropriate, and the present invention is not limited by this embodiment. The material of the elastic plate 53, the length of the slit 54, and the like are appropriately adjusted according to the food dough 10. In the present embodiment, the dusting mechanism 5 has a structure in which a belt member is wound around the rotating shafts 51A and 51B as the endless member 52. However, the number of rotating shafts, the material of the endless member 52, and the like are appropriately adjusted. It is.

Next, a third embodiment of the present invention will be described with reference to FIGS. 3rd Example in this invention changes the track | orbit of the elastic body plate of the powdering mechanism in the powdering apparatus 1 90 degree | times with respect to a conveyance direction with respect to 2nd Example, and is set as the upper powdering mechanism 6, It is the structure which provided the lower powder removal mechanism 7 below. Constituent elements similar to those of the powdering device 1 of the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

In this embodiment, the powder 11 is also adhered to the lower surface of the food dough 10 by previously spreading the powder 11 on the transport surface of the transport means 2. At this time, a relatively large amount of powder 11 is dispersed on the conveying means 2 and adheres to the lower surface of the food dough 10 so that the conveying means 2 and the food dough 10 do not stick. The food dough 10 on which the powder 11 has been dispersed is further conveyed below the upper powdering mechanism 6.

The upper powdering mechanism 6 is horizontally provided with rotating shafts 61A and 61B in the same direction as the conveying direction A of the conveying means 2, and an endless member 62 is wound around the rotating shafts 61A and 61B so as to be able to go around, The endless member 62 is provided with a plate clamping portion 63. In the present embodiment, the endless member 62 uses an endless belt, and plate clamping portions 63 are fixed to the endless belt at six locations at equal intervals by screws.

The plate clamping part 63 clamps a plurality of elastic plates as a set. In this embodiment, the plate clamping part 63 clamps the elastic plates 64A, 64B and 64C as a set in the width direction. The elastic plates 64A, 64B, and 64C have different height dimensions, and are provided higher on the rear side than on the front side with respect to the rotation direction of the endless member 62. According to FIG. 5, the elastic plate 64B is higher than the elastic plate 64A, and the elastic plate 64C is higher than the elastic plate 64B. A slight gap is provided between the elastic plates 64A, 64B and 64C.

The elastic plates 64A, 64B, and 64C have spatula-like portions 66A, 66B, and 66C by providing a plurality of slits 65A, 65B, and 65C at the radial outer edges, respectively. Further, the slits of the pair of elastic plates 64A, 64B and 64C do not overlap each other. In the present embodiment, the elastic plates 64A and 65C are 210 mm in length in the width direction, and slits 65A and 65C are provided at intervals of 5 mm from the side end. The elastic plate 64B is 205 mm in length in the width direction, and slits 65C are provided at intervals of 5 mm from the side end. The plate clamping portion 63 is clamped so that the centers in the width direction of the pair of elastic plates coincide. Therefore, when viewed from the front with respect to the traveling direction of the pair of elastic plates, the elastic slits 65A and 65C and the slits 65B are provided alternately.

The upper powdering mechanism 6 rotates the endless member 62 by the rotation of rotating shafts 61A and 61B that are interlocked and connected to a control motor (not shown). At this time, the movement trajectory of the elastic body plate 64 has a width direction component W that relatively moves in a direction intersecting the conveyance direction by the conveyance means 2. The elastic body plate 64 is close to the conveying means 2 from above, is in contact with the food dough 10, and is kept in contact with the food dough 10 while being in the conveying direction A along the width direction component W. After moving a certain distance in the crossing direction, the food dough 10 is separated. When the elastic plate 64 moves in sliding contact with the food dough 10, the spatula-like portions 65A, 65B, and 65C level the powder 11 respectively.

In this embodiment, a lower powdering mechanism 7 is provided below the upper powdering mechanism 6. The lower powdering mechanism 7 is horizontally provided with a rotating shaft 71 in a direction intersecting with the conveying direction A of the conveying means 2. The rotary shaft 71 is a shaft having a hexagonal cross section, and the elastic plate 72 is fixed to each side of the shaft with a screw or the like, but the present invention is not limited to this embodiment. For example, a configuration similar to that of the first embodiment of the present invention may be used. The elastic plate 73 includes the spatula-shaped portion 75 by providing a plurality of slits 74 at the outer peripheral edge of the elastic plate 73.

The part where the lower powdering mechanism 7 is provided in the conveying means 2 in the third embodiment has a configuration in which a plurality of endless round belts 8 are wound around a rotating shaft at intervals. Details are omitted because they are used. The trajectory of the tip of the spatula 75 passes above the conveying surface of the round belt 8, and the spatula 75 contacts the lower surface of the food dough 10 through the gap between the round belts 8, The powder 11 more than necessary attached to the lower surface of the food dough 10 is removed. The present invention is not limited to this configuration, and may be provided so that the spatula portion 75 of the lower powdering mechanism 7 can come into contact with the lower surface of the food dough 10.

In the top powdering mechanism 6 of the third embodiment of the present invention, the same effects as those of the first and second embodiments can be expected. That is, there is an advantage that it is easy to cope with a reduction in the possibility of foreign matter contamination, a change in the thickness of the food dough, and surface irregularities. In addition, at this time, since the three spatula portions 65A, 65B and 65C are overlapped as described above, the dusting effect can be kept relatively high. Further, since the slits of the elastic plates 64A, 64B, and 64C do not overlap each other, it is possible to prevent the leakage from the slits. For example, even if the slit 65A is opened and the powder 11 is leaked, the subsequent spatula-like portion 66B can remove the powder, so that the powder 11 may remain linearly on the food dough 10. Absent. Moreover, since each height dimension is provided differently, it can respond to the unevenness | corrugation of the food dough 10 surface, and can reduce the possibility of omission. Moreover, since the lower powder removing mechanism 7 for removing the powder on the lower surface of the food dough 10 is provided, it contributes to the production of a higher quality product that can remove the unnecessary powder 11 from the surface of the food dough 10. To do.

The description of the conveying apparatus according to the third embodiment of the present invention is generally as described above, but the present invention is not limited to this. For example, an abutting member on which the spatula-shaped portion 65 can abut may be provided in front of the position where the spatula-shaped portion 65 of the upper powdering device 6 contacts the upper surface of the food dough 10. Thereby, the impact when the spatula-shaped part 75 contacts the side edge part of the food dough 10 can be relieved, and problems such as turning up the side edge part of the food dough 10 can be prevented. In this embodiment, the elastic plates 64A, 64B and 64C are different in height, or the present invention is not limited to this. The heights of the elastic plates 64A, 64B and 64C are not limited thereto. The dimensions may be the same.

Although the main embodiments of the present invention have been described above, various modifications can be made within the scope of the claims. For example, the present technology can be used with the food dough 10 as a hemispherical dough piece such as a bun.
