Description

The present invention relates to a powder applying apparatus and a powder applying method for applying powder to food.

In a powder application device that applies powder such as wheat flour to the surface of the food while transporting the food such as meat by a conveyor, not only the food surface side exposed upward but also the food back surface side facing the conveyor. Various methods for applying powder are known.

Generally, the powder is first applied to the front side of the food facing upward, then the food is turned over to switch the directions of the front side and the back side, and the powder is applied to the back side of the food facing upward. The method of painting is widely known.

In addition, as a method of applying powder to the front side and the back side of the food without inverting the food, the food is conveyed by a net conveyor configured in a mesh shape, and the food on the net conveyor is transmitted from above and / or below the net conveyor. A method of flying powder toward the surface is known. According to this method, the powder from above the net conveyor adheres to the food surface side, and the powder from below the net conveyor passes through the opening of the net conveyor and adheres to the food back surface side. For example, Patent Document 1 discloses an apparatus for applying powder to the upper surface and the lower surface of a confectionery by spraying the powder onto the confectionery placed on the mesh belt from above and below. Further, in Patent Document 2, the powder is flipped up by a rotor with blades provided below the net conveyor, and the powder is blown upward toward the food against the force of gravity to spread the powder on the upper surface and the lower surface of the food. Disclose the device to which it adheres.

Further, Patent Document 3 discloses an apparatus for adhering powder to food by spraying powdered food on food using an air flow from a blower. Further, Patent Document 4 discloses an apparatus for scattering the powder toward the suspended noodles in order to attach the powder to the entire noodles.

However, the above-mentioned conventional device has the following problems.

For example, in the method of turning the food upside down during transportation and turning it upside down, there is a concern that the food may be damaged because the force is applied to the food when the food is turned over. If the food being transported is damaged, the yield may decrease, and a part of the damaged food may adhere to the conveyor. A part of the food adhering to the conveyor may come into contact with another food conveyed by the conveyor and cause further problems such as food damage. Further, in this method, it is possible to apply a sufficient amount of powder to the front surface side and the back surface side of the food, but the amount of the powder applied to the side surface side of the food is insufficient, and the surface of the food The amount of powder applied tends to be uneven between the back surface side and the side surface side.

Further, in the method of adhering the powder to the food by flying the powder toward a part of the food (for example, the upper surface of the food) as in the apparatus disclosed in Patent Documents 1 to 3, the powder is directly applied to the part. On the other hand, the powder is not directly applied to other parts. Therefore, in such a method, the powder may be excessively adhered to the portion of the food, and the thickness of the powder applied to the portion may be too large as compared with the other portion, and the powder may be applied to the entire food. It is difficult to apply the body evenly.

For example, in the apparatus of Patent Document 1, since the configuration in which the powder is directly sprayed on the food by air is adopted, the powder adheres excessively to the surface of the food on which the powder is sprayed. Especially when the surface of the food is moist, the powder may adhere to the food in the form of lumps (that is, the state of lumps), which may adversely affect the quality of the food.

Further, in the apparatus of Patent Document 2, since a configuration is adopted in which the powder is blown toward the food on the net conveyor by a rotor with blades provided below the net conveyor, the powder is applied to the lower surface of the food. It adheres excessively and it is difficult to spread the powder evenly throughout the food. Further, in the method using a rotating brush such as a rotor with blades, there is a risk that powder may stick to the rotating brush or the brushes such as the blades of the rotating brush may fall off. The powder that has once stuck to the rotating brush and then peeled off from the rotating brush and the brush that has fallen off from the rotating brush may adhere to food as foreign matter, so the method using the rotating brush is not always an appropriate powdering method. Absent.

Further, also in the apparatus of Patent Document 3, since the configuration in which the powdered food material is sprayed on the food by the air flow is operated, the powder is excessively adhered to the surface of the food on which the powder is sprayed, and the powder is spread over the entire food. It is difficult to apply the body evenly. In particular, in the apparatus of Patent Document 3, since the powder is sprayed on the food placed on the transport belt having no holes, it is not possible to apply an appropriate amount of powder to the bottom surface of the food in contact with the transport belt.

Further, since the apparatus of Patent Document 4 has a configuration in which powder dropped from above is sprayed onto food (that is, noodles) by an air flow flowing in one direction, the portion of the food to which the powder is sprayed is actually It is difficult to attach the powder to the whole food because the powder adheres only to the food. Further, since it is necessary to suspend the food with the device of Patent Document 4, the device of Patent Document 4 cannot be used when powder is applied to the food that is difficult to suspend.

As described above, it is difficult to uniformly apply the powder over the entire surface of the food with the device that directly blows the powder toward the food. To apply the powder evenly over the entire surface of the food, instead of flying the powder toward the food and attaching the powder directly to the food, the powder is blown up around the food. A method of adhering the soared powder to the entire surface of food is effective. In particular, in order for the powder to adhere uniformly over the entire surface of the food, a sufficient amount of powder is blown up around the food, and the airflow that lifts the powder is turbulent, and the powder is randomly spread around the food. It is effective to move it.

However, the devices disclosed in Patent Documents 1 to 4 described above cannot sufficiently cause the powder to fly up around the food. For example, in the apparatus of Patent Document 1, powder is sprayed toward the food from the powder outlets provided above and below the food, but the two powder outlets do not face each other and are not opposed to each other. The powder ejected from the powder outlet basically travels in only one direction. Further, in the apparatus of Patent Document 2, since the rotor with blades flips up the powder below the food, it is difficult to raise the powder in a sufficient state on the upper side of the food. Further, in the apparatus of Patent Document 3, the air flow for transporting the powder is ejected from the ejection pipes directed in a plurality of directions, but the ejection pipes do not face each other, and the air flow from each ejection pipe. Because they are offset from each other, it is not possible to create a turbulent air flow, and it is difficult to make the powder fly around the food in a random state. Further, in the apparatus of Patent Document 4, the fan is provided in only one place, and the air flow for transporting the powder basically flows in only one direction. Therefore, a sufficient amount of powder should be blown up around the food. Is difficult.

The present invention has been made in view of the above circumstances, and by adhering the powder blown up by the airflow to the food, it is possible to prevent the amount of the powder adhering to the food from being excessively biased according to the adhering location. It is an object of the present invention to provide a body-imparting device and a powder-imparting method.

[First Embodiment]
FIG. 1 is a perspective view showing the overall configuration of the powder applying apparatus 10 according to the first embodiment.

The powder applying device 10 includes an endless conveyor 14 on which food is placed, and a first housing 11 through which the food conveyed by the conveyor 14 passes. Further, the powder applying device 10 includes a second housing 12 arranged outside the first housing 11. Further, the powder application device 10 ejects a powder supply unit 25 that supplies powder to the inside of the first housing 11 and a blower gas for soaring and scattering the powder in the first housing 11. A blower port (first blower port) of the blower 21 and a blower port (second blower port) of the second blower 22 are provided.

FIG. 2 is a cross-sectional view simply showing the first housing 11 and the conveyor 14 according to the first embodiment.

The conveyor 14 is configured as a so-called net conveyor by an endless wire net in which a large number of openings 33 are formed. When the food H is conveyed by the conveyor 14, the food H is placed on the conveyor 14 so as to cover a part of the plurality of openings 33 of the conveyor 14. Therefore, in each food H conveyed by the conveyor 14, not only the upper surface and the side surface are exposed to the outside, but also the lower surface is exposed to the outside through the opening 33. The ratio of the opening area of the opening 33 in the conveyor 14 is not particularly limited, but from the viewpoint of evenly applying the powder to the entire food H, the ratio of the opening area of the opening 33 is preferably as large as possible, for example, 50. % Or more, more preferably 70% or more, still more preferably 90% or more.

Although the ratio of the opening area of the opening 33 of the conveyor 14 formed of the wire net and the degree of exposure of the surface (particularly the lower surface) of the food H are correlated with each other, they do not always match. .. That is, the degree of exposure of the lower surface of the food H varies depending on the contact area between the conveyor 14 and the food H. On the other hand, the contact area between the conveyor 14 and the food H is not necessarily uniquely determined from the ratio of the opening area of the opening 33 of the conveyor 14. For example, even if the width of the single wire constituting the conveyor 14 is 2 mm, when the cross-sectional shape of the wire is a circle or the like, the food H on the conveyor 14 comes into contact with the wire only in the vicinity of the top of the wire. .. In this case, the contact width of the food H with respect to the wire is smaller than 2 mm (for example, about 1 mm), and the exposed area of the lower surface of the food H is larger than the opening area of the opening 33. Further, the exposed area of the lower surface of the food H also fluctuates depending on the softness of the food H, and the softer the food H, the larger the contact area between the food H and the wires constituting the conveyor 14, and the lower surface of the food H. The exposed area becomes smaller. However, as the ratio of the opening area of the opening 33 of the conveyor 14 increases, the exposed area of the lower surface of the food H also tends to increase, and if the ratio of the opening area of the opening 33 of the conveyor 14 is 50% or more, It becomes possible to apply the powder over a wide range to the lower surface of the food H.

The conveyor 14 travels continuously, travels from the outside to the inside of the first housing 11 through the insertion port 31 of the first housing 11, and also goes through the discharge port 32 of the first housing 11 to the first housing. It proceeds from the inside of 11 to the outside.

In the powder applying device 10 shown in FIG. 1, conversion rollers rotatably supported by the support 15 are provided in each of the conveyor conversion portions A1 to A6, and the conveyor 14 is hung on these conversion rollers. Assuming that the side on which the food H is placed is the front side and the side on which the food H is not placed is the back side of the conveyor 14, the back side of the conveyor 14 in contact with the conversion rollers in the conveyor conversion portions A1, A2, A4 and A5. In the conveyor conversion portions A3 and A6, the surface side of the conveyor 14 is in contact with the conversion roller. The conveyor 14 is guided by the conveyor conversion units A1 to A6 and continuously travels while changing the traveling direction, and the food H placed on the conveyor 14 is conveyed from the conveyor conversion unit A1 to the conveyor conversion unit A2. .. Each food item H is passed onto the conveyor 14 from a device provided before the powder applying device 10 in the conveyor conversion unit A1, and is provided after the powder applying device 10 in the conveyor conversion unit A2. Is passed from the conveyor 14.

The conveyor conversion units A1 to A2 are provided at the same height position (that is, a vertical position), and the conveyor 14 runs horizontally between the conveyor conversion unit A1 and the conveyor conversion unit A2. On the other hand, the conveyor conversion portions A3 to A6 are provided at lower height positions than the conveyor conversion portions A1 to A2, and the conveyor 14 runs below the first housing 11 particularly between the conveyor conversion portions A4 and the conveyor conversion portion A5. To do. By continuously traveling the conveyor 14 while changing the traveling position of the conveyor 14 in the height direction in this way, it is not necessary to move the return path side of the conveyor 14 in and out of the first housing 11, so that the opening of the first housing 11 The portion can be limited to the insertion port 31 and the discharge port 32.

The first housing 11 is a member for partitioning a closed space for raising the powder, and is a part around a part of the conveyor 14 (in the example shown in FIG. 1, between the conveyor conversion portion A1 and the conveyor conversion portion A2). It is provided so as to surround (partly around). In the present embodiment, the openings provided in the first housing 11 that communicates the inside and the outside of the first housing 11 are only the insertion port 31 and the discharge port 32, and are between the inside and the outside of the first housing 11. The flow of gas (atmosphere) is possible only through the insertion port 31 or the discharge port 32. It is not preferable that the powder blown up inside the first housing 11 leaks to the outside of the first housing 11. Therefore, the opening areas of the insertion port 31 and the discharge port 32 are preferably as small as possible within a range that does not obstruct the passage of the food H on the conveyor 14.

On the other hand, the blower ports 37a and 37b of the first blower 21 and the second blower 22 provided inside the first housing 11 eject the blown gas toward the inside of the first housing 11. That is, the blown gas is sent from the first blower 21 to the first blower port 37a, and the blown gas is sent from the second blower 22 to the second blower port 37b. In the powder applying device 10 shown in FIG. 1, a part of the casings of the first blower 21 and the second blower 22 is exposed to the outside in a state of being in contact with the first housing 11 without a gap, and the inside of the first housing 11 is exposed. It constitutes a part of the wall part (particularly the side wall part and the bottom wall part) for isolating the space from the outside. In FIG. 2, the first blower 21 and the second blower 22 are shown to be arranged in the internal space of the first housing 11 for easy understanding, but the first blower 21 of the present embodiment is shown. And, as shown in FIG. 1, the second blower 22 constitutes a part of a wall portion for isolating the internal space of the first housing 11 from the outside. However, the arrangement state of the first blower 21 and the second blower 22 is not particularly limited, and the first blower 21 and the second blower 22 may be arranged in the internal space of the first housing 11 as shown in FIG.

The first blower port 37a of the first blower 21 and the second blower port 37b of the second blower 22 are provided below the conveyor 14 inside the first housing 11 and are arranged so as to face each other. .. Therefore, the blown gas blown from the first blower port 37a of the first blower 21 and the blower gas blown out from the second blower port 37b of the second blower 22 are the first blower port 37a and the second blower port 37b. In the intermediate area between and, they collide with each other to form a turbulent gas flow. The powder in the first housing 11 is randomly blown up by the gas flow in the turbulent flow state, and not only exists in a scattered state in the space below the conveyor 14, but also passes through each opening 33 of the conveyor 14. It also exists in a scattered state in the space above the conveyor 14.

Therefore, while the food H placed on the conveyor 14 passes through the inside of the first housing 11, the powder existing in the internal space of the first housing 11 in a scattered state randomly contacts the food H. As a result, the powder can be adhered substantially uniformly over the entire food H. In particular, according to the powder applying device 10 as described above, which attaches only the powder blown up by the gas flow to the food H, a relatively heavy lump (that is, a lump formed by agglomeration of powder). Can be effectively prevented from adhering to food H.

Each of the first blower 21 and the second blower 22 communicates with the suction ports 36a and 36b, and these suction ports 36a and 36b open inside the first housing 11. Therefore, each of the first blower 21 and the second blower 22 allows the gas inside the first housing 11 sucked through the suction ports 36a and 36b to pass through the first blower port 37a and the second blower port 37b. 1 It is ejected as a blown gas toward the inside of the housing 11. The first blower 21 and the second blower 22 perform gas suction and blow gas ejection in a state where the powder is blown up inside the first housing 11. Therefore, powder is mixed in the gas sucked by the suction ports 36a and 36b, and powder is also mixed in the blower gas ejected from the blower ports 37a and 37b.

The suction ports 36a and 36b of the first blower 21 and the second blower 22 are opened outside the first housing 11 to allow powder-free gas (that is, the atmosphere) to enter from the outside of the first housing 11. It may be sent as a blown gas toward. However, from the viewpoint of preventing the leakage of powder from the inside of the first housing 11 to the outside as much as possible, the gas inside the first housing 11 is introduced rather than the gas being introduced from the outside to the inside of the first housing 11. It is preferable to circulate, and it is preferable that the suction ports 36a and 36b of the first blower 21 and the second blower 22 are opened inside the first housing 11.

Each of the above-mentioned first blower 21 and second blower 22 can have an arbitrary configuration, and typically, a line flow fan or an axial fan is used to configure the first blower 21 and the second blower 22. can do. The line flow fan is also called a cross flow fan, and the suction direction of the gas through the suction ports 36a and 36b and the discharge direction of the blown gas through the blower ports 37a and 37b are different, for example, the suction direction of the gas. The direction in which the blown gas is discharged may be deviated by about 90 ° (see FIG. 2). On the other hand, in the axial fan, as shown by the signs "21a" and "22a" in FIG. 3, the suction direction of the gas through the suction ports 36a and 36b and the discharge direction of the blown gas through the blower ports 37a and 37b. Is basically the same. In the axial flow type first blower 21a and the second blower 22a, in order to suck a sufficient amount of gas through the suction ports 36a and 36b (that is, to discharge a sufficient amount of blown gas from the blower ports 37a and 37b). It is necessary to secure a space on the back side of the first blower 21a and the second blower 22a on which the suction ports 36a and 36b are formed.

Therefore, when the distance between the first blower port 37a of the first blower 21 and the second blower port 37b of the second blower 22 is widened, the first blower 21 and the second blower 22 may be configured by a line flow fan. preferable. The powder in the first housing 11 is efficiently blown up between the first blower port 37a of the first blower 21 and the second blower port 37b of the second blower 22, and adheres to the food H on the conveyor 14. Therefore, from the viewpoint of securing a wide range of powderable areas, it is preferable to configure the first blower 21 and the second blower 22 with a line flow fan. The first blower 21 and the second blower 22 of the present embodiment are composed of a line flow fan.

Each of the first blower port 37a of the first blower 21 and the second blower port 37b of the second blower 22 having the above configuration is not directed to the food H placed on the conveyor 14 inside the first housing 11. It is arranged like this. In the present embodiment, below the conveyor 14, the first blower port of the first blower 21 is in a direction parallel to the transport direction of the food H (that is, the moving direction of the conveyor 14 in the first housing 11) and facing each other. The second blower port 37b of the 37a and the second blower 22 is directed. As a result, the discharge direction of the blown gas from each of the first blower port 37a of the first blower 21 and the second blower port 37b of the second blower 22 becomes parallel to the transport direction of the food H, and the first blower 21 and the second blower 22 2 The blown gas from the blower 22 is not directly blown to the food H.

On the other hand, the powder supply unit 25 supplies powder to the inside of the first housing 11, especially between the first blower port 37a of the first blower 21 and the second blower port 37b of the second blower 22. In the powder application device 10 shown in FIG. 1, two powder supply units 25 are provided, and each of the one side wall side of the first housing 11 and the other side wall side facing the one side wall side. The powder supply unit 25 is arranged. The powder supplied by each powder supply unit 25 has a particle size smaller than the diameter of each opening 33 of the conveyor 14, and can freely move between the upper part and the lower part of the conveyor 14 through each opening 33. You can come and go to.

Each powder supply unit 25 shown in FIG. 1 has a pneumatic transport unit 42, a powder storage unit 43, and a powder outlet 41. An air guide pipe 47 and an air ejection pipe 48 are connected to the powder storage portion 43 for storing powder, and each of the air guide pipe 47 and the air ejection pipe 48 communicates with the inside of the powder storage portion 43. There is. The pneumatic transport unit 42 ejects the conveyed gas toward the powder stored in the powder storage unit 43 to cause the powder to fly up, thereby causing the powder to be blown out from the powder outlet 41. That is, the pneumatic transport unit 42 is connected to the air guide pipe 47, and the pneumatic transport unit 42 ejects the conveyed gas toward the powder in the powder storage unit 43 via the air guide pipe 47. The powder in the powder storage unit 43 to which the conveyed gas is sprayed is blown up, carried by the conveyed gas to the powder ejection port 41 via the air ejection pipe 48, and from the powder ejection port 41 into the first housing 11. It is blown out toward.

The powder ejection port 41 is installed inside the first housing 11, and is located between the first blower port 37a of the first blower 21 and the second blower port 37b of the second blower 22 with respect to the transport direction of the food H. It is provided in. Therefore, the powder blown out from the powder ejection port 41 is supplied between the first blower port 37a of the first blower 21 and the second blower port 37b of the second blower 22 inside the first housing 11. , It is blown up by the blown gas from the first blower 21 and the second blower 22. The height position of the powder ejection port 41 in the first housing 11 is not particularly limited, and the height positions of the first blower port 37a of the first blower 21 and the second blower port 37b of the second blower 22 (that is, vertical). It may be substantially the same, may be higher, or may be lower than the directional position).

The powder ejection port 41 is arranged inside the first housing 11 so as not to be directed toward the food H placed on the conveyor 14. In the powder applying device 10 shown in FIG. 1, a powder ejection port 41 is provided on the side wall surface of the first housing 11, and the powder ejection port 41 is directed in the horizontal direction perpendicular to the transport direction of the food H. ing. Therefore, the powder from the powder outlet 41 is blown out in a direction perpendicular to the discharge direction of the blown gas from the first blower port 37a and the second blower port 37b.

A powder hopper 44 is connected to the powder storage unit 43 via a screw conveyor 45. The screw conveyor 45 has a structure in which a rotating screw (not shown) is provided in the pipe. When the rotary screw is rotationally driven by the screw drive motor 46, the powder in the powder hopper 44 is gradually supplied into the powder storage section 43 via the screw conveyor 45.
