Description

  According to the present invention, a group of powder particles received from the receiving port into the stirring chamber forming member is transported in the longitudinal direction of the stirring chamber forming member into the cylindrical stirring chamber forming member in a sideways posture. The present invention relates to an agitating and conveying apparatus provided with a spiral rotating body that is discharged from an outlet.

  Such an agitating / conveying device is provided with a spiral rotating body inside a cylindrical stirring chamber forming member in a sideways posture, and a group of powder particles received from the receiving port into the stirring chamber forming member is spiral rotating body. Thus, the agitating chamber forming member is conveyed in the longitudinal direction and discharged from the discharge port.

  In such a stirring and conveying apparatus, conventionally, the spiral rotating body is formed by bending a plate body in a spiral shape on the outer peripheral portion of a shaft body provided along the longitudinal direction of the stirring chamber forming member. The configuration is such that the screw blades are fixed in a state where the longitudinal direction thereof is along the axial direction of the shaft body, and the powder blade group is conveyed while being pushed and moved by the screw blades as the shaft body rotates. (For example, see Patent Document 1)

JP-A-5-137521

  In the above-described prior art, since the powder particles are conveyed while being pushed and moved by the screw blades as the shaft rotates, the powder particles are moved in the longitudinal direction of the stirring chamber forming member. However, there is a disadvantage that the function of stirring the granular material group is not sufficient.

  If the explanation is added, according to the above configuration, the screw blade is in a plate shape from the connecting portion with the shaft body, that is, from the radially inner end to the radially outer end, The screw blade is closed from the radially inner end to the radially outer end. Therefore, when the shaft body is rotated, the powder group tends to be pushed and moved as it is in the axial direction by the screw blades, and the relative positional relationship between the adjacent powder bodies hardly changes. In many cases, it is transported in almost the same posture in the state, and the function of stirring the granular material group is not sufficient.

  The present invention has been made in view of such circumstances, and the purpose thereof is to allow the granular material group received in the stirring chamber forming member to be favorably conveyed along the longitudinal direction of the stirring chamber forming member. An object of the present invention is to provide an agitating and conveying apparatus capable of improving the function of agitating a powder body group.

The stirring / conveying device of the present invention has a granular material group received in the inside of the stirring chamber forming member from a receiving port in the longitudinal direction of the stirring chamber forming member inside the cylindrical stirring chamber forming member in a sideways posture. It is provided with a spiral rotating body that is transported and discharged from the discharge port,
In the first characteristic configuration, the spiral rotator is formed with a hollow inside of the spiral conveying action unit,
A feature of the present invention is that a stirring rotator is provided inside the spiral rotator to rotate around an axis along the longitudinal direction of the spiral rotator to stir the powder particle group.

  That is, the spiral rotating body having a hollow inside of the spiral conveying action portion is rotated around the axis along the longitudinal direction of the stirring chamber forming member, and the stirring rotation is performed inside the spiral rotating body. Since the body is rotated around the axial center along the longitudinal direction of the spiral rotator, the granular material group exists on the bottom side in the stirring chamber forming member by the spiral conveying action part of the spiral rotator. And being stirred by a stirring rotating body that rotates inside the spiral rotating body while being transported along the longitudinal direction of the stirring chamber forming member while moving inward and outward in the radial direction of the spiral transporting action portion. Thus, the sheet is satisfactorily conveyed along the longitudinal direction of the stirring chamber forming member while being well stirred.

In other words, the spiral rotating body in which the inside of the spiral conveying action portion is hollow is provided with an internal space continuous in the longitudinal direction of the stirring chamber forming member on the radially inner side, and the helical conveying action portion It is formed in a state where the gap is opened so as to communicate with the internal space.
Then, as the helical rotating body is driven to rotate, the granular material group is pushed and moved along the longitudinal direction of the stirring chamber forming member by the helical conveying action unit. In addition, since the spiral conveying action part in the spiral rotating body extends spirally along the longitudinal direction of the stirring chamber forming member, the function of pushing and moving the granular material group along the longitudinal direction of the stirring chamber forming member It is possible to smoothly push and move the granular material group by the spiral conveying action part while fully exhibiting the above, and the granular material group is in a state where the stagnation of its fluid state is sufficiently suppressed, It can be satisfactorily conveyed along the longitudinal direction of the stirring chamber forming member in a state of being present on the bottom side of the stirring chamber forming member.

  In addition, since the spiral conveying action portion of the spiral rotating body is opened so that the space between the spiral conveying action portions communicates with the internal space, the granular material group is formed at the bottom of the stirring chamber forming member. In the state of being present on the side, while being pushed and moved in the longitudinal direction of the stirring chamber forming member by the helical conveying action part, it moves inward and outward in the radial direction of the helical conveying action part, and further, the helical conveying action The granular material group that has entered the internal space of the section is agitated by the agitating rotating body rotating in the internal space, and the granular material group can be sufficiently agitated.

  In other words, simply by rotating the spiral rotating body, the powder body group flows in a layered state in a state where the layer state is not disturbed so much that it is accumulated on the bottom side of the stirring chamber forming member. Although it is difficult to sufficiently stir the body group, the powder flowing in layers on the bottom side of the stirring chamber forming member by rotating the stirring rotating body inside the spiral conveying action portion By lifting up a part of the body group and turning it, it becomes possible to actively disturb the powder body group flowing in a layered manner, and it becomes possible to effectively promote the stirring of the powder body group. It is.

  Therefore, a stirring and conveying device capable of improving the function of stirring the granular material group while being able to favorably convey the granular material group received in the stirring chamber forming member along the longitudinal direction of the stirring chamber forming member. Can now be offered.

In addition to the first feature configuration, the second feature configuration is
The stirring rotator is formed in a rod shape extending along the longitudinal direction of the spiral rotator at a position away from the rotational axis of the spiral rotator, and rotates integrally with the spiral rotator. It is characterized by being provided.

  That is, the stirring rotator is formed in a rod shape extending along the longitudinal direction of the spiral rotator at a position away from the rotational axis of the spiral rotator, and is provided so as to rotate integrally with the spiral rotator. Therefore, by the stirring rotating body extending in a rod shape from a position away from the rotational axis of the spiral rotating body, the granular material group accumulated on the bottom side of the stirring chamber forming member is removed by the length of the stirring chamber forming member. It is possible to efficiently lift and stir over a wide range in the direction, and further promote the stirring of the granular material group.

Further, since the stirring rotator rotates integrally with the spiral rotator and the stirring rotator and the spiral rotator rotate at the same rotational speed, the rotational speeds of the stirring rotator and the spiral rotator are the same. Compared to the case where the particle group is different, it is possible to suppress the powder group from being stressed by being sandwiched between the spiral rotating body and the stirring rotating body. Damage can be suppressed.
In addition, by configuring the stirring rotator to rotate integrally with the spiral rotator, the configuration can be simplified as compared with the case where the stirring rotator is configured to rotate separately from the spiral rotator. Therefore, it is possible to reduce the cost.
Accordingly, while reducing the cost, the function of stirring the powder particles can be further improved, and damage to the powder particles associated with the stirring can be suppressed.

The third feature configuration is in addition to the second feature configuration,
The upper end of the spiral rotating body in the particle group transport direction is configured to be supported by the drive rotating section,
The stirring rotating body is formed in a U-shape that is reversed on the lower side in the powder group transport direction, and the upper end of the powder group transport direction is supported by the drive rotation unit in a cantilever state. It is characterized by being provided in

  That is, the drive rotating part is provided on the upper side in the conveying direction of the granular material group with respect to the stirring chamber forming member, and both the spiral rotating body and the U-shaped stirring rotating body are provided on the drive rotating part. Since the upper end portion in the conveying direction of the particle group is supported and provided in a cantilever state, it is possible to simplify the configuration for driving and rotating the helical rotating body and the stirring rotating body.

In addition, while a rod-like stirring rotator extending along the longitudinal direction of the spiral rotator at a position away from the rotational axis of the spiral rotator is supported by the drive rotation unit in a cantilever state, By forming the stirring rotator in a U-shape, the U-shaped stirring rotator is prevented from shaking with rotation, while the two rod-shaped portions of the U-shaped stirring rotator are used. Since the powder body group can be stirred, the stirring of the powder body group can be further promoted.
Accordingly, it is possible to further improve the function of stirring the granular material group while further reducing the cost.

In addition to any of the first to third feature configurations described above, the fourth feature configuration is
The powder is a rice grain, and is provided with a coating material solution supplying means for supplying a coating material solution for coating rice grains to a rice grain group located inside the stirring chamber forming member through a coating material solution supply port. Features.

  That is, since the coating material solution is supplied by the coating material solution supply means through the coating material solution supply port to the rice grain group that is conveyed while being stirred in the stirring chamber forming member by the spiral rotator and the stirring rotator, The rice grain group is conveyed while being stirred with the coating material solution, and the surface of the rice grain is coated with the coating material solution.

  That is, such a stirring and conveying device is, for example, a so-called non-washed rice in which the surface of rice grains from which all or almost all of the paste powder layer has been removed is coated with a coating solution such as a starch solution to form a film on the surface of the rice grains. May be used for washing-free rice production.

Then, as described above, the spiral rotator is formed with the inside of the spiral conveying action portion in a hollow state, and around the axis along the longitudinal direction of the spiral rotator within the spiral rotator. By providing a stirring rotator that rotates and stirs the granular material group, the spiral rotating body and the stirring rotator exert a stirring action in the same manner as described for the first characteristic configuration. The rice grains and the coating material solution can be sufficiently stirred, so that each rice grain can be properly coated with the coating material solution over the entire surface or almost the entire surface. It becomes.
Therefore, it has become possible to provide an agitating and conveying apparatus capable of appropriately covering the surface of rice grains with the coating material solution.

In addition to the fourth feature configuration, the fifth feature configuration includes:
The covering material solution supplying means supplies the covering material solution ejected from the covering material solution ejecting portion in an atomized state by mixing the air ejected from the air ejecting portion, and diffuses in the conveying direction of the rice grains. It is characterized by being configured to be supplied in a state where

  That is, the air ejected from the air ejection part and the coating material solution ejected from the coating material solution ejection part are mixed to atomize the coating material solution, and the atomized coating material solution forms a stirring chamber. It is supplied in a state of diffusing in the conveying direction of the rice grain group with respect to the rice grain group being conveyed in the member.

That is, since the coating material solution is supplied to the rice grains in a state of being atomized in this way, for example, even when a small amount of the coating material solution is supplied, the coating material solution is atomized. The rice grains are sprayed evenly as much as possible while diffusing over a wide range.
Moreover, since the atomized coating material solution is sprayed in a state of diffusing in the conveying direction of the rice grain group with respect to the rice grain group being conveyed in the stirring chamber forming member, the atomized state of the atomized state over the rice grain is as long as possible. Since the coating material solution can be sprayed, it is possible to coat each rice grain with the coating material solution in a state where the variation in the coated state is further suppressed.

  Therefore, even when the supply amount of the coating solution supplied to the rice grains conveyed through the stirring chamber forming member per unit time is small, the coating of the surface of the rice grains with the coating solution is more appropriate. Can now be done.

In addition to the fourth or fifth feature configuration, the sixth feature configuration is
The covering material solution supply means is directed to a position located on the lower side in the rotational direction of the helical rotating body with respect to the bottom of the stirring chamber forming member as viewed in the longitudinal direction of the stirring chamber forming member. The coating material solution is supplied.

  That is, by the coating material solution supply means, the coating material solution is positioned on the lower side in the rotational direction of the spiral rotator with respect to the bottom in the stirring chamber forming member as viewed in the longitudinal direction of the stirring chamber forming member. Since the coating material solution is supplied toward the location, the coating material solution is conveyed to the stirring chamber forming member while suppressing the supply of the coating material solution to the location where the rice grain group is not present in the stirring chamber forming member. It is possible to ensure that the rice grains are accurately supplied.

That is, the rice grain group is transported in the longitudinal direction of the stirring chamber forming member by the spiral rotating body in a state of being unevenly distributed on the lower side in the rotational direction of the spiral transporting body at the bottom of the stirring chamber forming member.
Therefore, the coating material solution is supplied toward a position located on the lower side in the rotational direction of the helical rotating body from the bottom in the stirring chamber forming member as viewed in the longitudinal direction of the stirring chamber forming member. This makes it possible to accurately supply the coating material solution to the rice grain group being conveyed while being stirred in the stirring chamber forming member, thereby further suppressing variation in the covering state of each rice grain. It becomes possible to coat | cover with a coating material solution in a state.
Therefore, the surface of the rice grain can be coated more appropriately with the coating material solution.

By being agitated, it is conveyed well along the longitudinal direction of the agitating chamber forming member 50 while being well agitated, and the coating material solution is supplied from the coating material solution supply port 56 to the rice grains that are agitated and conveyed in this way. The rice grain group and the coating material solution are stirred to coat the surface of the rice grain with the coating material solution, and the rice grain group whose surface is coated with the coating material solution is discharged from the rice grain discharge port 57. The

When the rice grain conveying device 3 is activated, the controller C causes the rice grain supply shutter 62 of the rice grain supply unit 60 to close after a set waiting time (for example, about 0.4 to 0.7 seconds) has elapsed. It is controlled to be switched to the open state.
That is, since the rice grain supply shutter 62 is opened after the rice grains are collected in the rice grain supply hopper 61, the rice grains are supplied into the stirring chamber forming member 50 in a state in which variation in the supply amount is suppressed from the time of activation. Therefore, it becomes possible to suppress the variation in the covering state of the rice grains.
Incidentally, when the rice grain transport device 3 is activated with the rice grain supply shutter 62 opened, the supply state of the rice grains into the stirring chamber forming member 50 at the time of activation becomes unstable. Before the coating material solution is supplied into the stirring chamber forming member 50, the rice grains reach the coating material solution supply position, and rice grains not covered with the coating material solution are generated, or the rice grains reach the coating material solution supply position. There is a possibility that rice grains with too much coating amount will be generated.

  The spiral rotating body 91 includes an internal space 91a that is continuous in the longitudinal direction of the stirring chamber forming member 50 on the radially inner side thereof, and the space between the spiral conveying action portions 91b communicates with the internal space 91a. 7, the rice grain group R is present on the bottom side in the stirring chamber forming member 50, and the stirring chamber is formed by the spiral conveying action portion 91b as shown in FIG. While being pushed and moved in the longitudinal direction of the member 50, the rice grain group R that has moved into and out of the radial direction of the helical conveying action portion 91b and entered the internal space 91a of the helical conveying action portion 91b is Stirring is performed in substantially the entire longitudinal direction of the stirring chamber forming member 50 by the rod-shaped stirring action portion 92a of the U-shaped stirring rotor 92 rotating in the internal space 91a. With enough material solution It is possible to 拌.

  That is, simply rotating the spiral rotor 91 causes the rice grain group R to flow in a layered state in a state where it is accumulated on the bottom side of the stirring chamber forming member 50 and the layer state is not disturbed so much. Although it is difficult to sufficiently stir the group R, as shown in FIG. 7, the U-shaped stirring rotator 92 is rotated inside the spiral conveying action portion 91 b of the spiral rotator 91. Thus, a part of the rice grain group R accumulated on the bottom side of the stirring chamber forming member 50 is lifted and turned by the rod-shaped stirring action portion 92a of the U-shaped stirring rotor 92, and flows in a layered manner. The rice grain group R that is present can be actively disturbed, and stirring of the rice grain group R is effectively promoted.

  Further, as shown in FIG. 4, the air sprayed from the spraying air ejection hole 81a of the coating material solution spray nozzle 81 and the coating material solution ejected from the coating material solution ejection hole 81b are mixed to form the coating material solution. Since the atomized coating material solution is supplied in a state of diffusing in the conveying direction of the rice grain group with respect to the rice grain group being conveyed in the stirring chamber forming member 50, for example, a small amount Even in the case of supplying the coating material solution, the coating material solution is sprayed on the rice grains as uniformly as possible in a state where the coating material solution is atomized and diffused over a wide range, and the atomized coating material solution Can be sprayed over a long time as much as possible to the rice grain group conveyed in the stirring chamber forming member 50.

  Further, as shown in FIG. 7, the coating material solution supply means 80 causes the coating material solution in the atomized state to be the bottom in the stirring chamber forming member 50 as viewed in the longitudinal direction of the stirring chamber forming member 50. Since it is supplied toward the position located on the lower side in the rotational direction of the spiral rotator 91, the supply of the coating material solution to the absence of the rice grain group R in the stirring chamber forming member 50 is suppressed. Then, it is accurately supplied to the rice grain group R being conveyed in the stirring chamber forming member 50.

  That is, the rice grains are transported in the longitudinal direction of the stirring chamber forming member 50 by the spiral rotating body 91 in a state of being unevenly distributed on the lower side in the rotational direction of the spiral transporting body 50 at the bottom of the stirring chamber forming member 50. The coating material solution is supplied toward a position located on the lower side in the rotational direction of the spiral rotator 91 with respect to the bottom of the stirring chamber forming member 50 as viewed in the longitudinal direction of the stirring chamber forming member 50. Thus, the coating material solution can be accurately supplied to the rice grain group being conveyed while being stirred in the stirring chamber forming member 50.

  And with respect to the rice grain group conveyed in the stirring chamber forming member 50, the coating material solution is brought into an atomized state while suppressing the supply of the coating solution to the non-existing location of the rice grain group in the stirring chamber forming member 50. It is possible to spray in a state that spreads over a wide range and for a long time as much as possible, so that each rice grain is coated with a coating solution in a state in which the variation in the coating state is further suppressed. It becomes possible to do.
