  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. For convenience of explanation, in each drawing, the right side in the drawing is the upstream side (rear) in the transfer direction, and the left side in the drawing is the downstream side (front) in the transfer direction.

  As shown in FIG. 1, the food powdering apparatus 10 according to the present invention includes a transfer unit 11, a powder input unit 41, and a powdering unit 51.

  The transfer unit 11 includes a conveyor 12, a powder removing unit 20 connected to the downstream side of the conveyor 12, and a return conveyor 23 disposed below the conveyor 12 and the powder removing unit 20.

  The conveyor 12 is for transferring a plurality of powdered articles W ... W, which are raw foods such as fried foods, and a powdery substance P such as bread crumbs from the upstream side in the transfer direction to the downstream side in the transfer direction. The high-speed conveyor 13 arrange | positioned at the side and the low-speed conveyor 17 connected to the downstream of the high-speed conveyor 13 are provided.

  As shown in FIG. 1, the high-speed conveyor 13 is arranged on the upstream side in the transfer direction, and places and transfers a plurality of powdered articles W... W with a gap D1 in the transfer direction. It fills and transfers the powdery material P to S1 between the thing W and the to-be-polished object W, and consists of an endless belt conveyor. A plurality of powdered articles W... W and a powdery substance P are placed on the upper surface of the belt 14 forming the placement surface of the high-speed conveyor 13, and the plurality of powdered articles W. W and powder P are sequentially transferred from the upstream side to the downstream side. In addition, an upper input portion 45 described later is provided above the upstream side of the high-speed conveyor 13.

  As shown in FIGS. 1 and 2, the low-speed conveyor 17 is connected to the downstream side of the high-speed conveyor 13, and is powdered with a plurality of powdered articles W... W that are transferred downstream by the high-speed conveyor 13. The article P is transported to the low-speed conveyor 17 and is transferred to the downstream side. The endless net conveyor having the same width as the high-speed conveyor 13 and the belt 18 forming the mounting surface of the net conveyor It consists of a receiving plate 19 provided below. Similar to the high-speed conveyor 13, a plurality of powdered articles W... W and a powdery substance P are placed on the upper surface of the belt 18 that forms a placement surface, and the belt 18 circulates and moves. W... W and powdery substance P are sequentially transferred from the upstream side to the downstream side. When the plurality of powdered articles W... W and the powdery material P transferred to the downstream side by the high speed conveyor 13 are transferred to the low speed conveyor 17 to be transferred, at least a plurality of the objects to be placed and transferred on the high speed conveyor 13 are transferred. Of the powdered articles W... W, the powdered article W placed on the front end side of the high-speed conveyor 13 and the plurality of powdered articles W. A state in which S1 (a position indicated by an arrow P in FIG. 2) is filled with the powdery object P between the powdery object W placed on the rear end side thereof. Further, between the front end of the high-speed conveyor 13 and the rear end of the low-speed conveyor, there is provided a transfer plate 27 made of a plate-like member having the same width as that of the high-speed conveyor 13 and having an inverted triangular cross section. The transfer plate 27 smoothly transfers the plurality of powdered articles W... W and the powdery material P transferred to the downstream side by the high-speed conveyor 13 to the low-speed conveyor 17, and at the time of the transfer, This is to prevent the powdered material from dropping from between the rear ends of the low-speed conveyor 17.

  The transfer speed of at least one of the high speed conveyor 13 and the low speed conveyor 17 can be adjusted, and the transfer speed of the low speed conveyor 17 is set to be lower than the transfer speed of the high speed conveyor 13. Thus, by setting the transfer speed of the low-speed conveyor 17 and operating the low-speed conveyor 17 at a lower speed than the high-speed conveyor 13, as shown in FIG. 2, it is placed on the low-speed conveyor 17 and transferred downstream. The distance between the front end Wf of the object to be powdered W to be transferred and the rear end Wb of the object to be powdered W transferred immediately before, that is, the low speed conveyor 17 The space | interval D2 between the some to-be-powdered articles W mounted is clogged. Therefore, compared with the interval D1 between the plurality of powdered articles W placed on the high-speed conveyor 13, the interval D2 between the plurality of powdered articles W placed on the low-speed conveyor 17 that has been transferred is set. Get smaller. In addition, the powdered material P placed in the space S2 between the plurality of powdered articles W is reduced by the distance D2 between the plurality of powdered articles W being reduced. It not only escapes into the space above the low-speed conveyor 17 and is piled up bulky, but is also pressed against the front ends Wf... Wf and the rear ends Wb. In some cases, when the powdery material P is pressed, the gaps between the individual powdery materials P and the gap between the front end Wf and rear end Wb of the material to be powdered W and the powdery material P are clogged. The density of the powdery substance P placed in the space S2 between the plurality of powdered articles W in 17 is the powdery substance P placed in the space S1 between the plurality of powdered articles W in the high-speed conveyor 13. It becomes large compared with the density. Therefore, the front end of the powdered article W is obtained by pressing the powdery substance P filled in S2 between the powdered article W and the powdered article W against the front end Wf and the rear end Wb of the powdered article W. The powdery substance P can be forcibly adhered to Wf and the rear end Wb. The performance of the high-speed conveyor 13 and the low-speed conveyor 17, in particular, the transfer speed adjustment area may be selected and used. For example, it is not necessary that the region for adjusting the transfer speed of the high speed conveyor 13 be a region that is faster than the region for adjusting the transfer speed of the low speed conveyor 17. The regulatory regions may overlap in whole or in part.

  The transfer speed of the low-speed conveyor 17 only needs to be slower than the transfer speed of the high-speed conveyor 13 and can be changed as appropriate. The transfer speed of the low-speed conveyor 17 is preferably set in the range of 50 to 99% of the transfer speed of the high-speed conveyor 13, and more preferably in the range of 70 to 95% of the transfer speed of the high-speed conveyor 13. When the transfer speed of the low-speed conveyor 17 is set to less than 50% of the transfer speed of the high-speed conveyor 13, the interval D2 between the plurality of powdered articles W placed and transferred on the low-speed conveyor 17 becomes unnecessarily small. As shown in FIG. 3, the object to be powdered W to be transferred from the high speed conveyor 13 to the low speed conveyor 17 rides on the object to be powdered W which has been transferred to the low speed conveyor 17 one time before, or the speed to the low speed conveyor is immediately before. There is a possibility that the shape of the object to be powdered W is deformed by colliding with the object to be powdered W which has been changed to 17. Moreover, when the transfer speed of the low speed conveyor 17 is set to be equal to or higher than that of the high speed conveyor 13, the interval D2 between the plurality of powdered articles W is widened, and the front and rear ends Wf and Wb of the powdered articles are excellently powdered. The effect cannot be obtained.

  Further, the interval D2 between the plurality of powdered articles W placed on the low speed conveyor 17 and transferred downstream is between the plurality of powdered articles W placed on the high speed conveyor 13 and transferred downstream. By becoming smaller than the interval D1, the powdery object P filled in the space S2 between the plurality of objects to be powdered W from the front ends Wf... Wf and the rear ends Wb. On the other hand, it is a distance to which a force is applied and may be a distance that takes productivity into consideration, and can be implemented with appropriate changes. The distance D1 between the plurality of objects to be powdered W placed on the high speed conveyor 13 and transferred downstream, more specifically, the front end Wf of the object to be powdered W to be transferred and the powdering to be transferred immediately before. The distance from the rear end Wb of the object W is desirably in the range of 10 to 100 mm, and more desirably in the range of 30 to 50 mm. By setting the interval D1 between the plurality of objects to be powdered W placed on the high speed conveyor 13 and transferred downstream to the above range, and operating the low speed conveyor 17 at a lower speed than the high speed conveyor 13, the low speed conveyor 17 The distance D1 between the plurality of powdered articles W that are carried out, changed, and transferred to the downstream side, and between the plurality of powdered articles W placed on the high-speed conveyor 13 and transferred downstream. More preferably, it should be reduced by about 5 to 20 mm, and more preferably about 7 to 15 mm. In this way, the transfer speed of the low-speed conveyor 17 with respect to the high-speed conveyor 13 and the intervals D1 and D2 between the plurality of powdered articles W placed on the high-speed conveyor 13 and the low-speed conveyor 17 and transferred downstream are adjusted. As a result, the powdery material P filled in the space S2 between the plurality of powdered articles W is pressed against the front ends Wf ... Wf and the rear ends Wb ... Wb of the plurality of powdered articles W ... W The powdery material P can be forcibly adhered to the front end Wf and the rear end Wb of the attachment W. In addition, each space of S1 between the powdered article W and the powdered article W in the high-speed conveyor 13 and S2 between the powdered article W and the powdered article W in the low-speed conveyor 17 is at least powdered. When a force is applied from the front end Wf and the rear end Wb of the attachment W to the powdery material P filled in the spaces S1 and S2, the space is directly related to the transmission of the force.

  The powder removing unit 20 further transfers the plurality of powdered articles W... W transferred from the low-speed conveyor 17 to the downstream side, and also describes an extra powdery material P that has not adhered to the powdered article W. It is for dropping onto the belt 24 of the return conveyor 23. In the present embodiment, a plurality of cylindrical rollers 21... 21 are arranged side by side so as to be rotatable in the transfer direction with a predetermined interval (hereinafter referred to as a gap) 22, and each is rotated by a rotating means (not shown). By rotating the cylindrical rollers 21... 21, the object to be powdered W is transferred to the downstream side, and the excess powdery material P that has not adhered to the object to be powdered W is belted on the return conveyor 23 described later. Drop onto 24. The gap 22 between the cylindrical roller 21 and the roller 21 can be arbitrarily set in consideration of clogging caused by the powdery material P or the like. Moreover, the structure of the powder removal part 20 is not restricted to the above-mentioned thing, You may implement it changing suitably.

  As shown in FIG. 1, the return conveyor 23 receives and places the powdery material P dropped from the powder removing unit 20 and transfers it to the upstream side of the high-speed conveyor 13. It consists of an endless belt conveyor of the same width. The return conveyor 23 has one end (the left side in the figure) disposed below the powder removing unit 20 and the other end (the right side in the figure) disposed below the upstream side of the high-speed conveyor 13. Is inclined such that the end portion (right side in the drawing) on the high speed conveyor 13 side is higher than the end portion (left side in the drawing) on the powder removal unit 20 side.

Specifically, the belt 24 of the return conveyor 23 is wound around the return wheel 25 and is pressed against the outer periphery of the guide wheel 16 provided on the winding wheel 15 around which the belt 14 of the high-speed conveyor 13 is wound from the lower side to the upper side. It is wound in the state. In this manner, the belt 24 of the return conveyor 23 is wound around the guide wheel 16 while being pressed against the guide wheel 16, so that a predetermined interval is provided between the belt 24 of the return conveyor 23 and the belt 14 of the high-speed conveyor 13. A guide portion 26 is formed, and the belt 24 of the return conveyor 23 moves together with the belt 14 of the high speed conveyor 13 as the guide wheel 16 of the high speed conveyor 13 rotates. The interval between the guide portions 26 formed between the belt 24 of the return conveyor 23 and the belt 14 of the high-speed conveyor 13 is not particularly limited, and may be set arbitrarily. As described above, the return conveyor 23 receives and places the powdery material P dropped from the powder removing unit 20, transfers the powdery material P to the lower side on the upstream side of the high-speed conveyor 13, and transfers it to the guide unit 26. The powder P sent to the guide 26 is fed to the high speed conveyor 13 so as to be held between the belt 24 of the return conveyor 23 and the belt 14 of the high speed conveyor 13. Thereby, the powdery substance P can be reliably circulated between the transfer parts 11. On the other hand, a part of the powdery material P transferred by the return conveyor 23 is dropped and placed on a powder supply conveyor 42 described later. Further, in the food powdering method and the food powdering device 10 according to the present invention, the food may be powdered without the return conveyor 23.

For example, the side pressing portion 55 includes a plurality of left and right side pressing pieces (not shown) formed in a plate shape described in Patent Document 1, and a plurality of support members (not shown) that support the left and right side pressing pieces. And a plurality of objects to be powdered W... W and a powdery material P are a plurality of left and right side pressing pieces and a belt on which the high speed conveyor 13 is placed. 14, while being transferred to the downstream side, the powdery material P is pressed against the object to be powder W from the left and right sides by a plurality of left and right side pressing pieces. You may comprise so that the powdery material P may adhere to the left and right side surfaces. Further, the side pressing portion 55 is composed of a pair of left and right rollers (not shown), and is arranged above the high-speed conveyor 13 and on the left and right sides at predetermined intervals, and a plurality of powdered articles W. And the powdery material P pass through between the plurality of left and right paired rollers and the belt 14 which is the mounting surface of the high-speed conveyor 13 and are transferred to the downstream side. Alternatively, the powdery material P may be pressed from the left and right sides so that the powdery material P adheres to the left and right side surfaces of the object to be powdered W.

  Next, about the powdering method of the foodstuff which attaches the powdery thing P to the powdery thing W using the powdering apparatus 10 of foodstuff, the powdery thing W immersed in the batter liquid is used as the powdery substance P. The case where it adheres to bread crumbs will be described. First, the bread crumbs P are placed on the belts 14 and 18 of the high speed conveyor 13 and the low speed conveyor 17 and circulated between the transfer units 11. In this circulation, the bread crumbs P placed on the high speed conveyor 13 and the low speed conveyor 17 fall on the return conveyor 23, and the bread crumbs P placed and transferred on the belt 24 of the return conveyor 23 are connected to the belt 24 of the return conveyor 23. In a guide path 26 formed between the belt 14 of the high-speed conveyor 13 and the belt 14 and 24 of both the return conveyor 23 and the high-speed conveyor 24, it is fed from the return conveyor 23 to the high-speed conveyor 13. As a result, the bread crumb P automatically and continuously circulates between the transfer units 11. Further, a part of the excess bread crumbs P dropped and placed on the belt 24 of the return conveyor 23 and transferred upward from below is dropped and placed on the powder supply conveyor 42 and supplied to the upper input unit 45. The powder supply conveyor 42 can also place a new powdered material P accommodated in a hopper (not shown) and transfer it to the upper input unit 45.

  Next, a plurality of powdered articles W... W whose entire surface is covered with batter liquid are placed on the upstream side of the high-speed conveyor 13 on which the bread crumbs P are placed on the belt 14 forming the placement surface. At that time, a plurality of objects to be powdered W... W are placed at intervals D1 in the transfer direction. In this embodiment, it shall be mounted in the position of the upstream of the high-speed conveyor 13 shown by the arrow of FIG. Placement of the object to be powdered W may be performed manually. For example, a net conveyor (not shown) that forms part of a batter liquid immersion device (not shown) for the object to be powdered W on the rear end side of the high-speed conveyor 13. (Not shown) may be connected, and the object to be powdered W placed on the net conveyor may be continuously transferred from the net conveyor to the rear end side of the high-speed conveyor 13.

  In addition, the powdered article W placed on the high-speed conveyor 13 and transferred from the upper input portion 45 provided on the upstream side of the high-speed conveyor 13 is covered with the powdery substance P, and the powdered article W The bread crumbs P are dropped so that the space between the powder and the object to be powdered W is filled with the powdery material P, and the entire surface of the object to be powdered W placed on the rear end side of the high-speed conveyor 13 is the bread crumb P. While being covered, it is transferred in a state in which the powdered material P is filled in S1 between the material to be powdered W and the material W to be powdered.

  The object to be powdered W and the bread crumb P, which are placed and transferred on the high-speed conveyor 13, are transferred from the upstream side to the downstream side in the transfer direction. As it passes between the first to third pressing rollers 53, 53, 53 and the belt 14, it is pressed from above by the respective pressing rollers 53, 53, 53, and is applied to the upper and lower surfaces of the powdered article W. Bread crumb P is pressed. Further, when the object to be powdered W and the powdery object P which are placed and transferred on the high-speed conveyor 13 pass between the side pressing part 55 and the belt 14, the side pressing part 55 causes the object to be powdered. Since the width through which W and the powdery substance P can pass gradually decreases, the left and right side pressing portions 55 are moved as the bread crumb P placed and transferred on the high-speed conveyor 13 is transferred downstream. By the center. In that case, since the 3rd press roller 53 is arrange | positioned above the side pressing part 55, there is no escape place of bread crumb P, As a result, bread crumb P presses on the upper surface and lower surface of the to-be-powdered article W. At the same time, the left and right side pressing portions 55 are pressed against the left and right side surfaces of the object to be powdered W. Therefore, when the material to be powdered W passes the side pressing portion 55, the bread crumbs P are reliably attached to the upper and lower surfaces and the left and right side surfaces of the material to be powdered W.

  Next, as shown in FIGS. 1 and 2, a plurality of powdered articles W and bread crumbs P that have been transferred to the downstream side by the high-speed conveyor 13 are transferred to the low-speed conveyor 17 and transferred to the downstream side. To do. At that time, at least the powdered object W placed on the front end side of the plurality of powdered articles W... W in the high speed conveyor 13 and the rear end of the powdered articles W. It shall transfer in the state which filled with the powdery material P between S1 (position marked with the arrow P in FIG. 2) between the to-be-polished objects W mounted in the side. The transfer speed of the low-speed conveyor 17 is set to be lower than the transfer speed of the high-speed conveyor 13, and the low-speed conveyor 17 is operated at a lower speed than the high-speed conveyor 13. Compared with the distance D1 between the powdered articles W, the distance D2 between the plurality of powdered articles W placed and transferred on the low-speed conveyor 17 transferred and transferred is reduced, and the plurality of powdered objects The bread crumb P placed in the space S2 between the attachments W not only escapes into the space above the low-speed conveyor 17 due to the decrease in the interval D2, but is piled up bulky, and a plurality of the attachments W ... W is pressed against the front ends Wf... Wf and the rear ends Wb. As a result, the bread crumbs P can be forcibly adhered to the front end Wf and the rear end Wb of the object to be powdered W. By the above method, bread crumbs P can be reliably adhered to the entire surface of the object to be powdered W.

  Next, the object to be powdered W and the bread crumb P transferred to the front end of the low speed conveyor 17 are continuously transferred to the powder removing unit 20. As the plurality of cylindrical rollers 21... 21 rotate, the powder removing unit 20 transfers only the powdered article W to which the bread crumb P is firmly attached to the downstream side and does not adhere to the powdered article W. The excess bread crumbs P are dropped downward from the gap 22 formed between the cylindrical rollers 21 and 21. Excess bread crumbs P dropped downward are received by the return conveyor 23 as described above, and sent to the high-speed conveyor 13 again. As described above, the powdered material P can be uniformly and reliably attached to the entire surface of the object to be powdered W, particularly to the front and rear ends Wf and Wb of the object to be powdered W. When the powdered material P is powdered onto the material to be powdered W using a conventional powdering device, the powder material P partially peels off the material to be powdered W or the powder adhered to the material to be powdered W. The product defect due to the variation in the thickness of the powder P or the like occurred 2 to 3%, but when the powdered material P was powdered to the powder to be powder W using the food powdering apparatus 10 according to the present invention. The defect rate could be suppressed to almost 0%.

  In the present embodiment, endless belt conveyors are used for the high-speed conveyor 13, the return conveyor 23, and the powder supply conveyor 42. However, instead of a net conveyor or a plate conveyor that uses a net having a mesh shape formed on each belt. May be implemented. Moreover, although the endless net conveyor was used for the low speed conveyor 17, it may replace with an endless belt conveyor, a plate conveyor, etc. and may implement. Each configuration of the high-speed conveyor 13, the low-speed conveyor 17, the return conveyor 23, and the powder supply conveyor 42 deviates from the object of the present invention as long as a plurality of powdered articles W. It may be implemented with appropriate changes within the range not to be performed.

  In this embodiment, the case where bread crumb P is applied to the object to be powder W soaked in batter liquid is illustrated, but not limited to this form, such as powdering of meriken powder such as fried or tempura, fried powder, etc. Applicable when powdering with powder seasoning, powdering to ingredients soaked in seasoning liquid such as fried Tatsuta, powdering peanuts and other nuts, etc. It can be used in the case where various powders P are adhered to the material to be powdered W which is a raw material food.
