Description

  The present invention relates to a powder ring apparatus and a powder ring method for applying and attaching a powder material to the surface of a food material.

  For example, cooked foods such as deep-fried chicken and tempura are uniformly coated with powdered material such as starch and wheat flour on the surface of food ingredients such as meat, seafood and vegetables that have been cut into chunks of appropriate size. Is fried in hot oil. For this reason, in the food cooking process that mass-produces cooked foods such as fried foods, there is a processing process for applying and adhering the powder material to the surface of a large amount of food ingredients, and this processing process is performed manually by a cooking worker. It is done by mechanical processing with a powder ring device.

By the way, various research and development have been made on such a powder ring device. For example, a device described in Patent Document 1 described below has already been proposed. In the device described in Patent Document 1, a plurality of raised bodies are fixed to the inner peripheral surface of the drum, and the powder material enters the gaps between these raised bodies, and the powder material is sprinkled on the food that rolls in the drum. By doing so, the powder material is applied to the food.
JP 2001-299315 A

  However, when the food material with the powder material applied to the surface is discharged out of the drum and collected, the powder material not attached to the food material is discharged out of the drum together with the food material. If this is the case, unnecessary powdery material may be unevenly deposited on the surface of the collected food material, resulting in a problem that the quality of the cooked food is degraded.

  In addition, in such a case, there is another problem that it is necessary to separately remove unnecessary powder from the surface of the food material, and the cooking operation becomes complicated. Further, when unadhered powder material is discharged together with the food raw material to the outside of the drum, there is a problem that the unnecessary powder material is discarded and the powder material is wasted due to such disposal.

  The present invention has been made to solve the above-described problems, and while the food material in the powdered drum is reliably transferred from the drum supply port side to the drum discharge port side, it is attached to the food material. Provided is a powder ring device and a powder ring method capable of collecting only the food material to which the powder material is uniformly and sufficiently applied and adhered to the entire surface by retaining the powder material that is not in the powdered drum. The purpose is that.

  In order to solve this problem, a powder ring device according to claim 1 is for applying a powder material to the surface of a food material, and a powdered drum having a central axis formed in a substantially cylindrical shape with a substantially horizontal orientation. A drum supply port that opens at one end in the central axis direction of the powdered drum and feeds food raw materials and powder into the powdered drum, and the other end in the central axis direction of the powdered drum with respect to the drum supply port A drum discharge opening for discharging food raw material from the powdered drum formed in the opening, and a drum drive for rotating the powdered drum about its central axis to transfer the food raw material toward the drum discharge opening side A plurality of means and a rotationally driven inner peripheral surface of the powdered drum, and the powdered drum is rotationally driven in the forward direction so that the inner peripheral surface of the powdered drum is located at the uppermost position from the lowest point. When rotating toward the point Consists serial drum supply port side in the posture that is inclined downward toward the drum outlet side, and, and a transfer blade which rod-like protrusions of the plurality of the are shaped by Retsuritsu in a comb shape.

  The powder ring device according to a second aspect is the powder ring device according to the first aspect, wherein the plurality of transfer blades are substantially equally spaced in a circumferential direction of the powdered drum when the powdered drum is viewed in the axial direction. In each of the arrangement locations in the circumferential direction of the dusting drum, they are arranged in a constant width, and are arranged in series at substantially equal intervals and in parallel with the central axis direction of the dusting drum.

  The powder ring device according to claim 3 is the powder ring device according to claim 1 or 2, wherein the transfer blade is smaller than the size of the food material and between the plurality of rod-shaped protrusions forming the transfer blade and the size of the powder material A larger gap is provided.

  The powder ring device according to claim 4 is the powder ring device according to any one of claims 1 to 3, wherein the transfer blade has the plurality of rod-shaped protrusions arranged in a comb-teeth shape and separated from the powder drum. A base member that is formed and is detachably fixed to the inner periphery of the powdered drum is provided. Therefore, by removing the base member from the inner peripheral surface of the powdered drum, the plurality of rod-shaped protrusions arranged on the base member can be removed together.

  A powder ring method according to claim 5 is a method of applying and adhering a powder material to a food material using the powder ring device according to any one of claims 1 to 4, wherein the drum driving means attaches the powdered drum. A drum rotating step for rotating, a raw material supplying step for supplying food raw material from the drum supply port into the powdered drum rotated by the drum rotating step, and a powder material from the drum supply port separately from the raw material supplying step Is provided intermittently at predetermined time intervals, and a recovery step of recovering the food material discharged from the drum discharge port to the outside of the powdered drum is provided.

  The powder ring method according to claim 6 is the powder ring method according to claim 5, wherein at least one of the drum supply port and the drum discharge port sucks air around the drum supply port and the drum discharge port to float in the air. A suction recovery step of recovering the powder material to be performed.

  According to these powder ring apparatus or powder ring method, the food raw material and the powder material are supplied into the powdered drum from the drum supply port, while the powdered drum is rotated in the forward direction around the central axis by the drum driving means. Driven. When the powdered drum is rotated in the forward direction in this way, the inner peripheral surface of the powdered drum is rotated and fed from the lowest point to the highest point, so the food material in the powdered drum Is lifted to the upper side in the rotational direction following the rotation of the dusting drum while remaining on the inner circumferential surface of the dusting drum, and becomes unstable and becomes the bottom of the inner circumferential surface of the dusting drum. Roll around as if falling to the part.

  By rolling around the inside of the powdered drum in this way, the powder material is attached to the surface of the food material, and the food material is coated with the powder material. Further, when the food material rolls around in the powdered drum, it is made to collide with any of the transfer blades that are swung in the powdered drum. Here, when the dusting drum is rotated in the forward direction and the inner peripheral surface of the dusting drum is rotated from the lowest point to the highest point, each transfer blade is connected from the drum supply port side to the drum discharge port side. Therefore, the food material that collides with one of the transfer blades rolls along the transfer blade and is sent to the drum discharge port side. As a result, the food ingredients are gradually transferred from the drum supply port side to the drum discharge port side by the transfer blade while rolling around the powder drum, and finally discharged from the drum discharge port to the outside of the powder drum. Is done.

  On the other hand, the powder material supplied to the inner peripheral portion of the powdered drum is allowed to pass between the rod-shaped projections because a plurality of rod-shaped projections forming the transfer blade are arranged in a comb-teeth shape. For this reason, the powder material not adhered to the food material is prevented from being transferred together with the food material to the drum discharge port side by the transfer blade, and the powder material is retained in the powdered drum. As a result, only the food material coated with the powder material is separated from the powder material remaining without adhering to the food material and recovered from the drum outlet.

  According to the powder ring device of the first aspect, the plurality of transfer blades are rotationally driven in such a manner that the powder drum is rotated in the forward direction and the inner peripheral surface of the powder drum is rotated from the lowest point to the highest point. In this case, the posture is inclined downward from the drum supply port side toward the drum discharge port side. Therefore, for example, even if the center axis of the powdered drum is not inclined so as to be inclined downward from the drum supply port side to the drum discharge port side, the food raw material is rolled along the transfer blades one after another from the drum supply port side. There is an effect that it can be reliably transferred to the drum outlet side, and the powder material can be applied to the food material during the transfer.

  In addition, since the plurality of transfer blades are formed by arranging a plurality of rod-shaped protrusions in a comb-like shape, the powder material that has not been adhered to the food material while being fed into the powdered drum is referred to as the food material. There is an effect that it can be retained in the powdered drum without being discharged out of the powdered drum together. Therefore, the powder material that has not adhered to the food material and the food material are prevented from being discharged together with the powdered drum, and the unnecessary powder material is unevenly adhered to the recovered food material. There is an effect that it can be prevented. In addition, there is no need to remove unnecessary powder material from the collected food material, and there is an effect that it is not necessary to waste the powder material.

  According to the powder ring device of claim 2, in addition to the effect of the powder ring device of claim 1, when the powdered drum is viewed in the axial direction, the plurality of transfer blades are substantially equidistant in the circumferential direction of the powdered drum. Therefore, for example, a very small number of rod-shaped protrusions are formed on the inside of the powdered drum as compared with the case of forming a blade having a spiral shape from the drum supply port side to the drum discharge port side. There is an effect that a structure for transferring the food material in the powdered drum can be configured only by arranging the peripheral surfaces in a comb-like shape.

  In addition, the plurality of transfer blades are arranged at respective locations in the circumferential direction of the dusting drum, and are arranged in series at substantially equal intervals and in parallel with the central axis direction of the dusting drum. In other words, since a plurality of transfer blades are arranged in multiple stages at regular intervals in the central axis direction of the powdered drum, the food raw material that rolls around in the powdered drum is transferred to the next stage from the drum supply port side by the transfer blade of each stage. There is an effect that it is sent to the blade one after another and can be transferred to the drum outlet side.

  Therefore, it is not necessary to incline the center axis of the drum with powder greatly downward from the drum supply port side toward the drum discharge port side and to roll the food material to the drum discharge port side by the inclination. For this reason, it is possible to prevent the food raw material from rolling down and passing through the powdered drum from the drum supply port side to the drum discharge port side, ensuring sufficient time for the food raw material to stay in the powdered drum. Thus, the powder material can be uniformly and sufficiently adhered to the food material.

  In addition, since the food material can be transferred from the drum supply port side to the drum discharge port side even when the center axis of the powdered drum is kept substantially horizontal or close to the horizontal position, the powder material is powdered by the inclination of the powdered drum. The effect of allowing powder material to stay almost uniformly in the entire central axis direction of the powdered drum without slipping down inside the drum toward the drum discharge port side and staying in a large amount on the drum discharge side. There is.

  According to the powder ring device of claim 3, in addition to the effect of the powder ring device of claim 1 or 2, the gap between the rod-like projections in the transfer blade is smaller than the size of the food material and larger than the size of the powder material. Since it is large, it is possible to reliably feed the food material to the drum outlet side along the descending slope of the transfer blade while preventing the food material from passing through or pinching between the rod-shaped protrusions, and By passing the powder material between the rod-shaped projections of the transfer blade, it is possible to prevent the powder material from being sent to the drum discharge port side along the transfer blade, and to reliably retain the powder material in the drum with powder. There is an effect.

  According to the powder ring device of the fourth aspect, in addition to the effect exhibited by the powder ring device according to any one of the first to third aspects, each transfer blade has a plurality of bar-shaped protrusions integrally arranged on the base member. Therefore, by removing the base member from the inner peripheral surface of the powdered drum, the plurality of rod-shaped protrusions can be removed together for each transfer blade. For this reason, each of the transfer blades removed from the dusting drum can be individually and carefully cleaned and sterilized, and the hygienic management of the dusting drum can be easily performed.

  According to the powder ring method of claim 5, in addition to the same effect as the powder ring device of any one of claims 1 to 4 described above, by using such a powder ring device, it adheres to the food material Since powder material that has not been collected can be retained in the powdered drum, it is necessary to replenish the necessary and sufficient amount of powdered material only by supplying new powdered material intermittently to the powdered drum at regular intervals. Can do. Therefore, there is no need to continuously supply the powder material continuously, and as a result, it is possible to avoid wasteful supply of the powder material into the powdered drum.

  According to the powder ring method of claim 6, in addition to the effect of the powder ring method of claim 5, at least one of the drum supply port and the drum discharge port sucks the powder material floating in the surrounding air. Since it is sucked and collected by the apparatus, it is possible to collect the powder material that is going to fly out of the powdered drum, and to prevent the working environment from being deteriorated due to the floating diffusion of the powder material in the air. Moreover, there is an effect that the powder material scattered in the air can be collected and re-supplied into the powdered drum.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a side view of a powder ring device 1 according to an embodiment of the present invention, and a one-dot chain line in the drawing indicates a rotation axis (center axis) line of the powdered drum 2.

  The powdered drum 2 has a rotational axis arranged in a substantially horizontal posture, for example, a substantially horizontal posture, and the shape thereof is formed in a substantially cylindrical shape. A drum supply port 11 is formed at one end (right side in FIG. 1) of the powdered drum 2 in the rotation axis direction. The drum supply port 11 is an open part for supplying the food material G and the powder material K into the powdered drum 2. Further, a drum discharge port 12 is formed at the end opposite to the drum supply port 11, that is, at the other end (left side in FIG. 1) of the powdered drum 2 in the rotation axis direction. The drum discharge port 12 is an open portion for discharging the food material G from the powdered drum 2.

  The machine base frame 3 is a pedestal that supports the powdered drum 2 so as to be rotatable around a rotation axis, and on both sides of the upper width direction (perpendicular to the paper surface of FIG. 1, left and right direction of FIG. 3) One roller shaft 13 that supports the attached drum 2 in a state of being rotatable around the rotation axis is provided (see FIG. 3). Each roller shaft 13 is rotatably supported on the machine frame 3 by a bearing, and mainly has a shaft body 13a that is parallel to the dust drum 2 and an interval in the axial direction of the shaft body 13a. And a plurality of rollers 13b that are fixed by being opened.

  Each roller shaft 13 is circumscribed on both sides of each roller 13b in the direction intersecting the rotation axis of the dusting drum 2 (perpendicular to the paper surface in FIG. 1, left-right direction in FIG. 3) (see FIG. 3). A sprocket 14 is fixed to one roller shaft 13 coaxially with the plurality of rollers 13b. The sprocket 14 is connected to the rotary shaft 4 a of the drive motor 4 fixedly installed at the lower part of the machine base frame 3 via the chain belt 15.

  For this reason, the rotational force of the drive motor 4 is transmitted to one of the roller shafts 13 via the chain belt 15 to rotate the roller shaft 13. Then, the rotation of the roller shaft 13 is transmitted to the powdered drum 2 via the plurality of rollers 13b, and the machine base remains in a state where the powdered drum 2 is mounted between the two roller shafts 13 and 13. It is rotated on the frame 3.

  The food material supply conveyor 5 is a belt conveyor that continuously supplies a large number of food materials G from the drum supply port 11 into the powdered drum 2 one after another. The powder material supply device 6 is a device for supplying the powder material K from the drum supply port 11 into the powdered drum 2. Furthermore, the powdered drum 2 is connected to one end of different suction pipes 16 and 17 in communication with each other above both ends in the rotational axis direction. The suction pipes 16 and 17 are connected to the center of the powdered drum 2 in the rotational axis direction. They are joined together and connected to the suction device 7.

  The suction device 7 is fixedly installed at the lower part of the machine base frame 3, sucks air around both the drum supply port 11 and the drum discharge port 12 through the suction pipes 16 and 17, and the drum. The powder material K floating in the air around the supply port 11 and the drum discharge port 12 is collected in the powder material collection container 8.

  FIG. 2 is a development view of the inner peripheral surface of the powdered drum 2. The right side of the diagram in FIG. 2 corresponds to the drum supply port 11 side, the left side of the diagram in FIG. 2 corresponds to the drum discharge port 12 side, and the arrow X in FIG. The arrow Y in the figure is the circumferential direction of the powdered drum 2 and the rotation of the powdered drum 2 when the food material G is transferred from the drum supply port 11 side to the drum discharge port 12 side The direction (forward direction) is shown.

  As shown in FIG. 2, a plurality of transfer blades 20 are arranged in a substantially staggered arrangement on the inner peripheral surface of the developed drum 2 with powder, and the drum supply port 11 is arranged by the plurality of transfer blades 20. A substantially step-like structure that is inclined as a whole from the side toward the drum discharge port 12 is formed. Further, the transfer blades 20, 20 having substantially the same position in the rotation axis direction (arrow X direction) of the dusting drum 2 are substantially equidistant (powdered drum) in the circumferential direction (arrow Y direction) of the dusting drum 2. 2) and are arranged in series in a substantially parallel posture.

  Further, the powdered drums 20, 20, 20 having substantially the same position in the circumferential direction (arrow Y direction) of the powdered drum 2 are arranged at substantially equal intervals in the rotation axis direction (arrow X direction) of the powdered drum 2. In addition, they are arranged in series in a substantially parallel posture. Further, all the transfer blades 20 are rotationally fed so that the inner peripheral surface of the dusting drum 2 is moved from the lowest point to the highest point when the dusting drum 2 is rotationally driven in the forward direction (arrow Y direction). In such a case, the posture is inclined downward from the drum supply port 11 side toward the drum discharge port 12 side.

  Specifically, each transfer blade 20 has an inclination angle θ with respect to a reference line L substantially parallel to the rotation axis direction (arrow X direction) of the dusting drum 2 in a state where the inner peripheral surface of the dusting drum 2 is developed. The maximum range of values of the inclination angle θ is 0 ° <θ <90 °. Note that the value of the inclination angle θ of the transfer blade 20 is practically considered to be approximately in the range of approximately 10 ° to approximately 60 °. In FIG. Depicted as °.

  FIG. 3 is a longitudinal sectional view (figure) of the dusting drum 2 when the dusting drum 2 is projected (viewed in the axial direction) from the drum discharge port 12 side (left side of FIG. 2), and an arrow Y in the figure is The rotation direction of the drum 2 with powder is shown.

  As shown in FIG. 3, each of the transfer blades 20 described above is formed by arranging a plurality of rod-shaped protrusions 21 in a comb-like shape, and the powdered drum 2 is projected from the drum discharge port 12 side. In such a case, the powdered drum 2 is arranged at substantially equal intervals in the circumferential direction at substantially equal intervals. Each of the rod-like protrusions 21 in each of the transfer blades 20 is formed in the same shape, and is formed in a round bar shape.

  Further, each rod-like protrusion 21 is fixed by welding or screwing the base end portion thereof directly to the inner peripheral surface of the powdered drum 2, and the tip end portion thereof is formed into a substantially hemispherical dome-shaped curved surface. Has been. Furthermore, the transfer blade 20 is provided with a gap smaller than the size of the food material G and larger than the size of the powder material K between the plurality of rod-shaped protrusions 21 forming the transfer blade 20.

  In addition, the shape of each rod-shaped protrusion 21 is not necessarily limited to a round bar shape having a substantially circular cross section, and is a rectangular bar having a substantially polygonal cross section, or a strip shape having a substantially rectangular or substantially elliptical cross section. It may be a bar material.

  Next, a method of applying and attaching the powder material K to the food material G using the powder ring apparatus 1 configured as described above will be described. The food raw material G is a lump obtained by processing food materials such as meat, seafood, and vegetables into an appropriate size, for example, bite size.

  The powdered drum 2 is rotationally driven around the rotation axis of the powdered drum 2 via the drive motor 4 (drum rotating step). While the rotation of the powdered drum 2 is continued, the food raw material G is continuously supplied one after another from the drum supply port 11 into the powdered drum 2 by the food raw material supply conveyor 5 (raw material supply step). On the other hand, apart from the supply process of the food material G, the powder material supply device 6 intermittently supplies the powder material K from the drum supply port 11 at a predetermined time interval (powder material supply process).

  Then, in the rotating powdered drum 2, the rotation of the powdered drum 2 follows the rotation of the powdered drum 2 while the food material G remains on the inner peripheral surface of the powdered drum 2. Although it is lifted upward in the direction, it becomes unstable and turns around so that it falls on the inner peripheral surface of the powdered drum 2 toward the bottom portion by the weight of the food material G itself. And the powder material K which stays in the bottom part of the internal peripheral surface of the powdered drum 2 by adhering to the inside of the powdered drum 2 in this way, or adheres to the transfer blade 20, and is retained is a food material. It is made to adhere to the surface of G, and the powder material K is applied to the food raw material G.

  In addition, when the food material G rolls around in the powdered drum 2, the food raw material G is caused to collide with any of the transfer blades 20 swung in the powdered drum 2 by the rotation of the powdered drum 2. The food material G that collides with any of the transfer blades 20 rolls along the transfer blade 20 and is sent to the drum outlet 12 side. As a result, the food raw material G is gradually transferred from the drum supply port 11 side to the drum discharge port 12 side by the transfer blade 20 while rolling around the powdered drum 2, and finally the powder from the drum discharge port 12. It is discharged out of the attached drum 2 and collected (collection process).

  On the other hand, the powder material K supplied to the inner peripheral part of the powdered drum 2 is not transferred to the drum outlet 12 side along the transfer blade 20 like the food raw material G, but between the plurality of rod-shaped protrusions 21. Many of them are collected and retained at the bottom portion of the inner peripheral surface of the powdered drum 2.

  Therefore, the powder material K not adhered to the food material G is not transferred to the drum outlet 12 side by the transfer blade 20 together with the food material G, and the powder material K not adhered to the food material G is powdered. In the attached drum 2, it is separated from the food material and retained. As a result, the food material G coated with the powder material K is separated from the powder material K remaining without adhering to the food material G and recovered from the drum discharge port 12.

  In both the drum supply port 11 and the drum discharge port 12, the air around the drum supply port 11 and the drum discharge port 12 is sucked by the suction device 7, and this suction floats in the air around the drum supply port 11 and the drum discharge port 12. The powder material K to be recovered is recovered in the recovery container 8 (suction recovery process).

  Next, with reference to FIG.4 and FIG.5, the powder ring apparatus of 2nd Example which is a modification of the said Example is demonstrated. In the powder ring device of the second embodiment, the transfer blade is changed to be removable from the powdered drum with respect to the powder ring device 1 of the first embodiment.

  In addition, the number of the rod-shaped protrusions 21 for one unit of the transfer blade 20 is not necessarily limited to nine, and if the other conditions described in the first and second embodiments are satisfied, for example, It may be an odd number such as 5, 7, 11 or the like.

  The threaded shaft portion 21b of the rod-shaped protrusion 21 has a male screw threaded on the outer peripheral surface thereof, and is screwed and welded to a substantially central portion of the base plate 31 in the longitudinal direction (specifically, the arc direction). Further, the screw shaft portion 21 b penetrates the base plate 31 and protrudes to the back surface side of the base plate 31. In addition, a fitting pin 21c having a smaller diameter than the outer diameter of the main body portion 21a of the rod-shaped protrusion 21 is coaxially formed at the base end portion of each rod-shaped protrusion 21 on both sides of the rod-shaped protrusion 21 having the screw shaft portion 21b. It is integrally formed.

  All the fitting pins 21 c of the rod-like protrusions 21 are inserted and fitted into fitting holes provided in the base plate 31, and are welded to the base plate 31. Here, of at least one of the four bar-shaped protrusions 21 on both sides of the bar-shaped protrusion 21 having the screw shaft portion 21 b, the fitting pin 21 c penetrates the base plate 31 and passes through the base plate 31. It protrudes on the back side.

  Further, at least two fitting pins (hereinafter, these two fitting pins are referred to as “positioning pins”) 21 c protruding from the back surface of the base plate 31 are formed with a protruding amount smaller than that of the screw shaft portion 21 b. Yes. The remaining six fitting pins 21c are substantially flush with the back surface of the base plate 31.

As shown in FIG. 5, in the transfer blade 20, the protruding back surface of the base plate 31 is in contact with the inner peripheral surface of the dusting drum 2, and the two positioning pins 21 c are the inner periphery of the dusting drum 2. Respectively inserted into positioning holes 32 penetrating from the surface to the outer peripheral surface. Thus, by inserting the two positioning pins 21c into the positioning holes 32, the unitized transfer blade 20 is positioned at a predetermined position of the powdered drum 2 in an appropriate posture.

  Further, the screw shaft portion 21b of the transfer blade 20 is detachably inserted into the through hole 33 penetrating from the inner peripheral surface of the powdered drum 2 to the outer peripheral surface, and protrudes from the outer peripheral surface of the powdered drum 2. Yes. A knob 34 having a female screw that can be screwed with the screw shaft portion 21b is screwed onto the screw shaft portion 21b, and the transfer blade 20 is fastened to the inner peripheral surface of the powdered drum 2 by the knob 34. The transfer blade 20 is configured to be fixed to the inner peripheral surface of the powdered drum 2.
