Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, powders (powder such as wheat flour and rice flour, seasonings, spices, cracker flour, bread crumbs, etc. are added to foods that are lump-shaped, cut into lump shapes, or formed into lump shapes. This is a so-called mixed powder, and in the present specification, these are collectively referred to as “powder”).
[0002]
[Prior art and technical issues to be solved]
For example, when making deep-fried chicken, batter liquid is applied as necessary around the chicken cut into an appropriate size, and then appropriate powders are sprayed and fried in oil. As a device for spraying powders on foods, a device is known in which foods are buried in powders on a conveyor, and powders are powdered by applying pressure from multiple directions. (See Kaihei 7-163, JP-A-10-257876, etc.).
[0003]
However, in a device that transports food while filling it with powder, the batter liquid moves from the pressed surface to the weak surface or binds when large pressure is applied. The meat may break, and it is difficult to fully spray the powder around the food. In order to improve the adhesion between the food and the batter liquid, powder is directly applied to the surface of the food. In the case of so-called dusting, it is not a problem even if it is insufficiently sprayed. This is a big problem when it is intended to sprinkle the powder and present a clothing with a good texture. For this reason, it is still the case that such a thing is still performed manually.
[0004]
A drum-type device is known as an apparatus that can evenly apply powders to a lump-like food. As an example, an apparatus as shown in FIGS. 11 and 12 has been proposed (see Japanese Patent Laid-Open No. 61-85181). In this apparatus, food and flour are sent to the covering section 62 by the conveyor 61. The covering part 62 includes a rotatable drum 63 having a plurality of radially extending stirring rods 63a therein, a sieving part 64 integrally attached to the downstream side thereof, and a return located on the upstream side of the drum 63. And a drum 65, which is rotatably mounted on the machine base 66. A return conveyor 67 is disposed between the sieving portion 64 and the return drum 65.
[0005]
In this apparatus, the food and flour put into the drum 63 move downstream while being stirred together by the rotation of the drum 63 and the action of the stirring rod 63a. In the meantime, the whole surface of the food is sprinkled with flour. Food covered with flour and excess flour are transferred from the drum 63 to the sieving unit 64, food is transferred from the chute 68 to the discharge conveyor 69, and excess flour is returned from between the bars 70 of the sieving unit 64. It falls on the conveyor 67. The flour falling on the return conveyor 67 is thrown into the return drum 65 by the movement of the conveyor 67, scooped up by the return fin 71 rotating in the return drum 65, dropped to the conveyor 61 from the upper part, and again the drum 63. Supplied in.
[0006]
According to this apparatus, it is possible to continuously and automatically apply powders such as wheat flour to foods such as lump meat, and to obtain highly efficient foods with high efficiency. . However, the food is lifted and dropped by the stirring rod 63a along with the rotation of the drum 63, and the powder coated by the impact when dropped falls off from the food or the food is broken. There was a problem that it was not possible to achieve high quality powdering (spraying).
[0007]
In addition, since the inner peripheral surface of the drum 63 is a flat surface, the food that has not been lifted by the stirring rod 63a may slip without rotating on the flour. Furthermore, since the flour is hardly lifted by the stirring rods 63a extending radially, the flour tends to stay near the bottom of the drum 63. Thereby, depending on the food, sufficient powdering becomes difficult, and the food may be discharged from the chute 68 with an insufficient glare.
[0008]
Protruding bodies such as baffle plates and feed blades are formed in the rotating drum, and powder and coating material are put into it, and the mixture of both is improved by the action of the baffle plate to obtain a suitable coating. Such devices are known (see JP-A-11-113549, JP-A-7-328408, etc.). However, all of them try to improve the surface coating by stirring a large number of small objects together in a state of friction with each other. Thus, it cannot use for the apparatus which needs to sprinkle powders, avoiding foods colliding.
The present invention has been made in view of the circumstances as described above, and allows powders to be sprinkled in a stable state from above while giving a gentle rotational motion to the food in the glare part. This allows powders to be sprayed onto foods that can sufficiently apply powders to the entire peripheral surface of the food, and reduce the impact received by the foods as much as possible so that the foods are not broken. An object of the present invention is to provide a drum and a powder dusting device including the drum.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the drum for dusting foods according to the present invention is applied to foods in which the foods and powders are sprinkled on the foods by rotating the foods and powders inside. It is a drum for dusting powder, and the inner peripheral surface of the drum is secured with a gap of a size that allows food that has been put into the drum to partially enter without contacting the inner peripheral surface of the drum. In this way, a large number of raised bodies are formed, so that when powder is applied to food, there is always a space where the powder can enter between the food and the drum inner peripheral surface. It is characterized by being secured.
[0010]
In the above drum, when food and powders are put in the drum and rotated, the individual foods that are put in are in a position where a part of the food enters a gap formed between adjacent ridges. The held posture is maintained, the posture is maintained, and the drum is gradually lifted in the rotational direction from the vicinity of the bottom of the drum as the drum rotates. When the balance is lost, the drum falls downward while gently rotating.
[0011]
On the other hand, the powders stay in the vicinity of the bottom of the drum so as to fill the gaps between the adjacent raised bodies, and are gradually lifted upward in the rotational direction as the drum rotates. And even if the food has fallen away from the gap between the ridges, some of the powders are carried further up in the gap between the adjacent ridges and then dropped. The food is not broken by the fact that the food falls with a gentle rotation, and then the powders are sprinkled on the food so that it does not break, and everything around the food The powders are stably and sufficiently coated.
[0012]
In the present invention, the plurality of raised bodies may be a plurality of protrusions extending in the axial direction of the drum, or may be a plurality of independent protrusions. In any case, the adjacent raised bodies are arranged so as to secure a gap of a size that allows food that has been put into the drum to partially enter without contacting the drum inner circumferential surface. The It is a preferable aspect that the entire bulges or at least the vicinity of the tops thereof are made of a flexible and elastic material, so that breakage of food can be more reliably avoided. For example, the entire raised body may be made of a material such as a foamed resin material or rubber, and at least the vicinity of the top of the metallic raised body may be covered with a similar material. Further, preferably, the surface of the plurality of raised bodies is a curved surface that smoothly changes. Thereby, it is possible to further alleviate the impact when falling out of balance from a state where a part has entered the gap between the raised bodies.
[0013]
Preferably, the drum further includes a spiral feeding means configured to feed a food product coated with powders from the inlet side toward the outlet side as the drum rotates. By providing such a feeding means, it is possible to feed foods toward the outlet in a state of being separated from each other without colliding with each other, and there is no breakage of the food, and high quality powdered and sprinkled foods are obtained. It is done.
[0014]
The present invention further discloses a powder dusting device for food, comprising at least the above-mentioned drum and a driving means for giving a rotational motion to the drum. In a more preferred embodiment, the powder dusting device further includes vibration generating means for applying at least intentional vibration to the drum.
[0015]
Depending on the type and amount of the powders, or due to the behavior of the powders and foods, the powders may enter the gaps between the adjacent ridges and cannot easily fall. In such cases, insufficient powdering may occur. The vibration generating means is for avoiding such a situation, and applies vibration to at least the rotating drum when necessary or periodically. As a result, the powders held in the gaps between the ridges fall easily and reliably, and regular and regular powders continue to fall. In addition, the powder can be made to dance moderately in the drum by vibration, and the powder can be uniformly applied to the food.
[0016]
In a preferred embodiment, the powder dusting device according to the present invention includes a first cylindrical body having substantially no opening except for a supply port formed at one end and a discharge port formed at the other end, and one end. A powder dusting portion comprising: a second cylindrical body disposed in the first cylindrical body with the other end facing the supply port and the other end facing the discharge port; Comprising a machine base that supports the powder dusting portion so that the second cylindrical body can rotate, and a drive means for imparting rotational motion to at least the second cylindrical powder; The food and powder charged from the supply port enter the second cylindrical body, and the second cylindrical body is constituted by the above-described drum for dusting powder to food. Many permeation holes on the peripheral surface that allow the passage of the upstream area and powders but do not allow the passage of food Further downstream, and in the vicinity of the upstream end of the first cylindrical body, the powder for feeding the powder staying there into the second cylindrical body It is provided with a similar recirculation means.
[0017]
In this powder dusting device, the food and the powder charged in the dusting part are mixed with each other when the second cylindrical body rotates, and the above-mentioned food that is the upstream region of the second cylindrical body. The powder is sprayed on the food at the portion of the drum for dusting the powder. The foods and the surplus powders on which the powders are sprinkled move to the downstream region of the second cylindrical body, where the surplus powders and the powders that are sprinkled on the food more than necessary The kind passes through a large number of transmission holes and falls onto the inner peripheral surface of the first cylindrical body.
[0018]
The first cylindrical body has a shape that does not substantially have an open portion except for a supply port formed at one end and a discharge port formed at the other end, and the powders that fall on the inner peripheral surface are in the outside air Will not scatter. Therefore, in this powder dusting device, the working environment in the vicinity is always kept good. Further, the dropped excess powder moves along the inner surface of the first cylindrical body to the vicinity of the upstream end thereof, and from there, the powder is automatically recirculated into the second cylindrical body. Therefore, all of the charged powders can be used as a dusting material, and no waste occurs.
[0019]
In addition, when a spiral structure is attached to the inner surface of the second cylindrical body as a feeding means, by supplying food one by one according to the spiral pitch, food having a fragile surface can be obtained. The powders can be continuously sprayed while being separated from each other. The helical structure is preferable because the elastic material can reliably prevent the food from being broken like a resin hose or a foamed resin.
The powder dusting device may further include vibration generating means for applying intentional vibration to at least the upstream region of the second cylindrical body.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a drum for spraying powder on foods and an apparatus for spraying powder with the drum according to the present invention will be described with reference to the drawings. FIG. 1 is a side view showing the entirety of a powder dusting device A provided with a drum B for dusting foods according to the present invention, and FIG. 2 is a front view of the device A shown in FIG. is there. FIG. 3 is a perspective view of the powder dusting drum B, and FIG. 4 is an enlarged view of a part thereof.
[0021]
In the illustrated powder spraying device A for foods, the powder spray drum B includes a cylindrical body 21A having both ends open, and has an elastic surface as a convex raised body 23A on its inner peripheral surface. A large number of long members obtained by cutting a material such as a hose or a cylindrical synthetic resin foam into a semicircular cross section or an arc shape are fixed in the axial direction of the cylindrical body 21A. As can be seen with reference to FIG. 2, the ridges 23 </ b> A that run in parallel have the food P to be sprayed with the powders put into the drum B being the drum B (cylindrical body 21 </ b> A). ) Is not in contact with the inner peripheral surface, but a part of the inner peripheral surface is arranged so as to ensure a clearance S of a size capable of entering. Thereby, a space is always ensured between the food P that is partially inserted into the gap between the adjacent raised bodies 23A and 23A and the inner peripheral surface of the cylindrical body 21A.
[0022]
In the powder dusting drum B, although not essential, the linear member 25A made of a soft material such as a resin material over the entire length is moved along the locus of the linear member 25A by the rotation of the drum. The food P and the powders are spirally wound and fixed so as to be transferred to the outlet side (see FIG. 3).
[0023]
As shown in FIGS. 1 and 2, the above-described powder dusting drum B is rotatably supported on free wheels 52 arranged at four corners of the machine base 50 and attached to the machine base 50. The rotational force of the motor 53 is transmitted to the cylindrical body 21A via a belt 55A interposed between the rotating shaft of the motor 53 and the pulley 16A attached to the outer periphery of the cylindrical body 21A, and a powder dusting drum B rotates on the machine base 50.
[0024]
In this example, although not essential, vibration generating means 80 is disposed on the machine base 50 in order to intentionally apply vibration to the drum B. In this example, the vibration generating means 80 is an air hammer, and two sets of air hammers 80 composed of a striking head 81 and an actuator portion 82 are attached. The actuator section 82 is regularly supplied with compressed air via a control mechanism (not shown), and the striking head 81 is moved toward the cylindrical body 21A to intentionally vibrate the powder dusting drum B. . You may make it give a vibration at arbitrary times, not regularly. Instead of the air hammer 80, various vibrators can be used as the vibration generating means.
[0025]
The operation of the powder dusting device A will be described. The motor 53 is driven to rotate the powder dusting drum B. In this state or prior to rotation, food such as chicken cut into an appropriate size and optionally attached with batter liquid and powder are introduced into the supply port side of the cylindrical body 21A.
[0026]
The charged powder enters the gap between the adjacent raised bodies 23A in the vicinity of the bottom of the cylindrical body 21A and fills the gap. However, the food P is supported in a state where only a part of the food P enters the gap S formed between the adjacent raised bodies 23A. FIG. 5a shows this state. When the cylindrical body 21A rotates in this state, the food P is gradually lifted in the rotating direction along with the rotation of the drum 21A, and when the balance is lost, as shown in FIG. To do. In the process, powders existing near the bottom of the cylindrical body 21A are sprayed around the food.
[0027]
On the other hand, the powders filling the space formed between the food P that partially enters the gap between the adjacent raised bodies 23A and 23A and the inner peripheral surface of the cylindrical body 21A are drums. Along with the rotation of 21A, the food P is lifted further upward than the position where it falls, and then falls. As a result, the powder falls so as to be sprinkled on the food P (see FIG. 4).
[0028]
Since the food P falls with a gentle rotation, and the powders are then sprinkled on the food P, the powder dusting device A is used. Thus, the food P is not broken, and a sufficient amount of powder can be dusted stably around the food P. Further, since the raised body 23A is made of a flexible and elastic material and the surface is a curved surface that smoothly changes, the food P is not broken by dropping or rotating.
[0029]
In FIG. 5a, the raised body 23A has an oval cross section instead of a semicircular shape. In this case, as compared with the case of the raised body 23A having the cross-sectional shape shown in FIGS. 2 to 3, the food P and the tubular body that are partially included in the gap between the adjacent raised bodies 23A and 23A. The space area formed between the inner peripheral surface of 21A can be widened, and a larger amount of powders can be accommodated. As a result, the amount of the powder falling as if it is sprinkled from above increases, and the powder P is more sufficiently applied to the food P.
[0030]
FIG. 5b shows a case where the gap between the raised bodies 23A and 23A is set wider as a comparative example. The food P that has entered the gap between the raised bodies 23A and 23A is pulled up to a higher position by the rotation of the drum 21A and then falls, so that the food is easily broken by impact. Although not shown, when the gap between the raised bodies 23A and 23A is very narrow and the food P is placed on top of three or more raised bodies 23A, the food is Slip occurs between P and the top of the raised body 23A, and the food P cannot be rotated as necessary. If the rotation of the food P is insufficient, it is impossible to sufficiently spray the entire surface, which is also not preferable.
[0031]
In the illustrated embodiment, the cylindrical body 21A is provided with a spiral feeding means (linear member 25A) on the inner surface, and the food P coated with powders is stably delivered to the outlet. Sent to. By feeding the food P at intervals, the food P can be sent out toward the outlet in a separated state without colliding with each other, and a high-quality powder-sprinkled food can be obtained.
[0032]
Depending on the working environment, it may happen that the powders that have entered the gap (or the space) between the adjacent raised bodies 23A do not fall. However, in the powder dusting device described above, the powders held in the gaps between the ridges by operating the air hammer 80 to vibrate the cylindrical body 21A when necessary or periodically. Can be reliably dropped. As a result, regular and regular powders continue to fall, and the powders can be made to move moderately in the drum by vibration, so the powder is evenly applied to the food. To do.
[0033]
FIG. 6 shows another embodiment of a drum B for dusting powder onto food. Here, as shown in FIGS. 1 to 5, the raised body is not a large number of ridges (ridges 23 </ b> A) extending in the axial direction of the drum, but a large number on the inner peripheral surface of the cylindrical body 21 </ b> A. The formed protrusions 23B are individually independent. Here too, the adjacent protrusions 23B are arranged in such a way that a gap S of a size that allows the food P put into the drum 21A to partially enter without contacting the drum inner peripheral surface is secured. It is installed. It is not necessary to explain that the powder dusting drum B of this embodiment has the same effects as those shown in FIGS.
[0034]
FIG. 7 to FIG. 10 show another embodiment of the apparatus for spraying powder to food provided with the drum B for spraying powder to food. 7 to 10, reference numeral 10 denotes an outer cylinder made of a stainless steel plate or the like, and constitutes a first cylindrical body that is a part of the powder dusting portion C. In the outer cylinder 10, a cylindrical portion 11, an upstream side plate 12, and a downstream side plate 13 are integrally formed, and a supply port 14 and a discharge port 15 are formed in the upstream side plate 12 and the downstream side plate 13, respectively. Reference numeral 20 denotes an inner cylinder, which constitutes a second cylindrical body that is a part of the powder dust part C. The inner cylinder 20 has a cylindrical shape as a whole, and the outer cylinder 10 has a posture in which one end (upstream end) side faces the supply port 14 and the other end (downstream end) side faces the discharge port 15. It is installed inside.
[0035]
The inner cylinder 20 is composed of an upstream region portion 21 having a closed peripheral surface and a downstream region portion 22 having a large number of permeation holes on the peripheral surface that allow passage of powders but not food. (Refer to FIG. 9) The above-mentioned upstream region portion 21 uses the above-described drum B for spraying powders on food according to the present invention. In the illustrated example, the upstream region portion 21 is configured by assembling a hose 23 made of a resin material having a small diameter into a cylindrical shape in a dense state. However, as shown in FIGS. A structure in which a large number of protrusions (bumps 23A) are attached to the inner peripheral surface of the cylindrical body 21A, or as shown in FIG. 6, a large number are formed independently on the inner peripheral surface of the cylindrical body 21A. It will be understood that a large number of protrusions 23B may be formed. Of course, also in the embodiment shown in FIGS. 6 to 9, the widest portion between the adjacent hoses 23, that is, the gap S between the adjacent hoses 23 is the upstream region. A gap large enough to allow partial entry without contact with the contact portion (corresponding to the drum inner peripheral surface) between adjacent hoses 23 assembled in a dense state with the food introduced into the portion 21 It is said that.
[0036]
The downstream area portion 22 is about 3/5 the length of the upstream area portion 21 and is entirely constituted by a wire mesh 24 having a small stitch. Instead of a metal mesh, a punching metal or a cylindrical resin product in a mesh shape may be used. The outer diameter of the downstream region portion 22 is substantially the same as the diameter of the discharge port 15 of the outer cylinder 10.
[0037]
On the inner surface of the inner cylinder 20, a linear member 25 made of a soft material such as a resin material is provided over the entire length of the inner cylinder 20, and food and powders are moved along the trajectory of the linear member 25 by the rotation of the inner cylinder 20. It is spirally wound and fixed so as to be transferred from the supply port 14 side to the discharge port 15 side. The linear member 25 corresponds to the linear member 25A in the form shown in FIGS.
[0038]
Further, the linear member 18 is also transferred to the inner peripheral surface of the outer cylinder 10, and the powder is transferred from the discharge port 15 side to the supply port 14 side along the locus of the linear member 18 by the rotation of the outer tube 10. As shown in FIG. These helical structures are not limited to the linear members as shown in the figure, and in particular, the linear member 18 is of a screw type formed by continuously winding a long plate member in a spiral shape. Also good. Further, instead of the linear member 18, a long plate member is continuously wound in a spiral shape with a leading edge contacting the inner peripheral surface of the outer cylinder 10 on the outer surface side of the inner cylinder 20. It can also be a structure.
[0039]
In the vicinity of the upstream side end portion of the outer cylinder 10, as shown in FIG. The plate members 19 are fixed in a radial direction at a predetermined interval, and the upper side position reaches the inner peripheral edge position of the supply port 14 formed in the upstream side plate 12. A powder recirculation means 40 having an annular member 41 capable of covering a virtual circumferential portion formed by the upper side position of the plate member 19 is fitted to the supply port 14 with a non-rotating body. Has been.
[0040]
The powder recirculation means 40 includes the annular member 41 having a width substantially equal to the length of the upper side of the plate member 19 and a flange 42 extending outward from one end of the annular member 41. An opening 43 is formed in a portion of the annular member 41 which is the upper position in a posture fitted to the supply port 14, and a guide is provided on the side edge on the flange 42 side of the opening 43 obliquely downward and forward. A tongue piece 44 is attached. An attachment rod 45 is fixed to the front surface of the flange 42. As shown in FIG. 7, by fixing the other end of the attachment rod 45 to the machine base 50, the powder recirculation means 40 is not rotated. The moving body is fitted into the supply port 14 of the outer cylinder 10 (that is, even when the powder dust cover part C rotates, it does not rotate together). In this state, the leading end portion of the guide tongue piece 44 is made to enter the upstream region portion 21 of the inner cylinder 20, and preferably, the downstream side of the annular member 41 and the upstream side of the inner cylinder 20 are separated from each other. It can be in the form of a heavy cylinder.
[0041]
Reference numeral 50 denotes a machine base. In this example, the upper surface 51 is inclined. The outer cylinder 10 is rotatably mounted on the inclined surface via free wheels 52 arranged at four corners. The direction of the inclination is an upward slope in the drawing, that is, a direction in which the supply port 14 side of the outer cylinder 10 is lower and the discharge port 15 side is higher. A motor 53 is attached to the machine base 50, and a belt 55 is interposed between a pulley 54 attached to the rotating shaft and a pulley 16 attached to the outer periphery of the outer cylinder 10. Therefore, when the motor 53 is driven, the rotation is transmitted to the outer cylinder 10 via the belt 55, and the outer cylinder 10 is positioned on the machine base 50 such that the discharge port 15 side is positioned higher than the supply port 14 side. And rotates together with the inner cylinder 20. An unloading conveyor 60 is disposed near the lower side of the discharge port 15 of the machine base 50.
[0042]
Also in this embodiment, although not indispensable, vibration generating means 80 is disposed on the machine base 50 in order to intentionally apply vibrations to the powder dust cover part C. Also in this example, the vibration generating means 80 is an air hammer, and two sets of air hammers 80 composed of a striking head 81 and an actuator portion 82 are attached. Air pressure is periodically sent to the actuator unit 82 via a control mechanism (not shown), and the striking head 81 is moved toward the outer cylinder 10 to intentionally vibrate the powder dusting part C. As a result, vibration is transmitted to the powder dusting drum B. Note that vibration may be applied at any time, not periodically.
[0043]
The operation of the powder dusting device A will be described. The motor 53 is driven to rotate the powder dusting part C. In this state or prior to rotation, powders and food are fed from the supply port 14 into the upstream region portion 21 of the inner cylinder 20 using a feeding means such as a conveyor (not shown). The charged powder and food are mixed with each other by the action of the linear member 25 attached to the inner surface of the inner cylinder 20 (second cylindrical body) while rotating the powder dusting portion C, and the upstream region portion thereof. It moves from 21 toward the downstream area portion 22. In the meantime, the spraying of the powder on the food proceeds. The mode at the time of sprinkling is as described in detail in the description of the embodiment shown in FIGS. 1 to 5 including the operation of the vibration generating means 80, and is omitted here. As shown in the figure, in the impact from the outer cylinder by the air hammer attached to the machine casing 50, the required vibration is applied to the powder dusting drum B, that is, the upstream area portion 21 of the second cylindrical body. If this is not possible, it is effective to assemble a device such as an appropriate known vibrator.
[0044]
The foods and the surplus powders on which the powders are sprinkled are moved to the downstream area 22 as they are, and the surplus powders and the powders that are sprinkled on the food more than necessary are moved to the downstream area 22. The light passes through a large number of through holes 24 formed on the outer cylinder 10 and falls onto the inner peripheral surface of the outer cylinder 10 (first cylindrical body). The outer cylinder 10 has a shape that does not substantially have an open portion except for the supply port 14 and the discharge port 15, and powders that have fallen on the inner peripheral surface are confined in the outer cylinder 10 and scattered in the outside air. There is no.
[0045]
Further, since the powder dusting portion C is mounted on the machine base 50 in an inclined posture so that the discharge port 15 is positioned higher than the supply port 14, excess powder that has fallen is removed from the outer cylinder 10. It moves along the inner surface to the vicinity of its upstream end. Since the helical linear member 18 is attached to the inner surface of the outer cylinder 10, the movement of the powders proceeds quickly and reliably.
[0046]
The powders that have moved to the vicinity of the upstream end of the outer cylinder 10 are scooped upward along with the rotation of the outer cylinder 10 by the plate member 19 attached to the upstream end of the outer cylinder 10. Since the virtual circumferential portion formed on the upper side of the plate member 19 is closed by the annular member 41 of the powder recirculation means 40, the powder does not fall during scooping. As the outer cylinder 10 rotates, the powders scooped up by the plate member 19 sequentially reach the position of the opening 43 formed in the annular member 41. The powders that have reached the opening 43 fall from there, are guided by the guide tongue 44, and are returned to the upstream region portion 21 of the inner cylinder 20. As a result, all the charged powders are used as the dusting material, and no waste occurs.
[0047]
In this embodiment, since the powder dusting part C is mounted on the machine base 50 in an inclined posture so that the discharge port 15 is higher than the supply port 14, the powder particles C in the inner cylinder 20. And the food does not inadvertently fall to the downstream (discharge port 15) side due to its own weight, and the spiral linear member 25 is always attached by the action of the spiral linear member 25 attached to the inner surface of the inner cylinder 20. The movement restricted to 25 is performed. For this reason, the distribution of food and powders is also made uniform, and in the upstream region 21 of the inner cylinder 20, the process of dusting foods and powders proceeds as expected. As a result, it is possible to always obtain a food product in which powders are sprinkled as desired, and to prevent the food from being unexpectedly broken.
[0048]
【The invention's effect】
According to the drum for dusting powder onto food according to the present invention and the powder dusting device provided with the drum according to the present invention, the food is gradually lifted in the rotating direction as the drum rotates, and the balance is lost. Sometimes it falls down with gentle rotation. On the other hand, even if the food is falling, the powders are further conveyed upward along with the rotation of the drum, and then fall. The food is not broken by the falling of the food with gentle rotation, and then the powders are sprinkled on the food as well, and all the surroundings of the food It is possible to stably apply a sufficient amount of powders. Thereby, a high-commercial-powder powdered food is obtained.
