According to the present invention, a group of rice grains received in the inside of the stirring chamber forming member from the receiving port is conveyed in the longitudinal direction of the stirring chamber forming member into the cylindrical stirring chamber forming member in a sideways posture. A spiral rotating body for discharging,
The present invention relates to a rice grain coating apparatus provided with a coating material supply means for supplying a rice grain coating material to a rice grain group located inside the stirring chamber forming member from a location on the lower side of the rice grain conveyance direction than the receiving port.

Such a rice grain coating apparatus conveys a group of rice grains received from the receiving port to the inside of the stirring chamber forming member in the longitudinal direction of the stirring chamber forming member by means of a spiral rotating body, and the coating material supply means provides a coating for rice grain coating. By supplying the material to the rice grain group located inside the stirring chamber forming member, the coating material is attached to the surface of the rice grain and discharged from the discharge port.
Such a rice grain coating apparatus is, for example, a water-soluble dietary fiber (for example, indigestible dextrin) capable of improving health functions such as a function of lowering blood sugar levels as a coating material, such as health and nutrition. By attaching a coating material capable of improving the function to the surface of the rice grain, it is used for manufacturing processed rice for manufacturing processed rice that is improved in functions such as health and nutrition.
That is, the coating material is usually supplied in a solution form to the rice grains located inside the stirring chamber forming member, and such a coating material solution is adhered and discharged from the outlet of the stirring chamber forming member. The rice grain group to be processed is supplied to a drying device, and the coating material solution on the surface of the rice grain is dried by the drying device to produce processed rice.

JP-A-5-137521

By the way, processed rice is usually manufactured by stacking and attaching a plurality of types of coating materials in the form of a layer or the like on the surface of rice grains.
For example, when a nutritional function is added to rice grains, a plurality of types of coating materials containing different nutrients may be stacked and adhered to the surface of the rice grains.

However, in the above-described conventional technology, as described below, there is a problem in that the production efficiency is low when the processed rice is produced by stacking and attaching a plurality of types of coating materials on the surface of the rice grain.
That is, as in the prior art, in the configuration in which the coating material supply means supplies one type of coating material into the stirring chamber forming member from one place on the lower side of the rice grain transport direction than the receiving port, for example, the rice grain group is formed in the stirring chamber Repeating the coating process of passing through the member and drying the rice grain group discharged from the discharge port of the stirring chamber forming member with a drying device over a plurality of times while changing the coating material supplied by the coating material supply means. As a result, a plurality of types of coating materials are stacked and adhered to the surface of the rice grain, and thus the production efficiency is low.

  In addition, in the configuration in which the rice grain group is conveyed while being pushed and moved by the screw blade as the shaft rotates, the function of conveying the rice grain group along the longitudinal direction of the stirring chamber forming member is sufficient. Although it can be exerted, since the function of stirring the rice grain group is not sufficient, the covering material could not be uniformly attached over the entire surface of the rice grain.

  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 rice grain group tends to be pushed and moved in the axial direction as it is by the screw blades. Therefore, the rice grain group is almost in a state where the relative positional relationship between adjacent ones hardly changes. It was often transported in the same posture, and the function of stirring the rice grains was not sufficient.

  The present invention has been made in view of such circumstances, and its purpose is to improve the production efficiency of processed rice in which a plurality of types of coating materials are deposited on the surface, and moreover, a plurality of types of coating materials. It is an object of the present invention to provide a rice grain coating apparatus capable of evenly depositing each over the entire surface of the rice grain.

The rice grain coating apparatus according to the present invention conveys the rice grain group received from the receiving port to the inside of the stirring chamber forming member in the longitudinal direction of the stirring chamber forming member into the cylindrical stirring chamber forming member in a sideways posture. A spiral rotating body that is discharged from the discharge port,
A covering material supply means for supplying a covering material for covering rice grains to a rice grain group located inside the stirring chamber forming member from a location on the lower side of the rice grain conveying direction than the receiving port is provided,
In the first characteristic configuration, the spiral rotator is formed with a hollow inside of the spiral conveying action unit,
The coating material supply means is configured by dispersing and arranging a plurality of coating material supply portions having different types of coating materials to be supplied at different locations in the rice grain conveying direction of the stirring chamber forming member. .

  That is, the rice grains are moved in and out of the agitating chamber forming member in the radial direction of the inside of the agitating chamber acting member by the spiral rotating body having a spiral conveying action portion having a hollow inside. Different types of coating materials are supplied into the stirring chamber forming member from a plurality of coating material supply sections that are transported in the longitudinal direction and dispersedly arranged at different locations in the rice grain transport direction of the stirring chamber forming member. By simply passing the rice grain group through the stirring chamber forming member once, a plurality of types of coating materials are adhered to the surface of the rice grain in a state in which each coating material is evenly adhered over the entire surface of the rice grain. Can be made.

  Incidentally, the plurality of coating material supply units can include a coating material that is supplied in the form of a solution, a coating material that is supplied in the form of a powder, and the like. Then, coating the surface of the rice grain by attaching the coating material to the surface of the rice grain means that the coating material in the form of a solution or powder covers the whole surface of the rice grain or the entire surface of the rice grain. It includes a form that is attached to the surface of the rice grain in the state of being.

  That is, the spiral rotating body in which the inside of the spiral conveying action portion is hollow has an internal space continuous in the longitudinal direction of the stirring chamber forming member on the radially inner side thereof, and between the spiral conveying action portions. Is formed in an open state so as to communicate with the internal space, and the spiral conveying action portion of the spiral rotating body is communicated with the internal space between the spiral conveying action portions. Since the rice grains are opened, the rice grains are pushed and moved along the longitudinal direction of the stirring chamber forming member by the spiral conveying action part while moving in and out of the radial direction of the helical conveying action part. The rice grains can be transported satisfactorily along the longitudinal direction of the stirring chamber forming member while being sufficiently stirred by the movement of the spiral transporting action portion in and out of the radial direction.

Then, the rice grains are mixed with the covering material supplied from the covering material supply unit on the upper side in the rice grain conveying direction, and the covering material covers the entire surface of the rice grains or is dispersed over the entire surface of the rice grains. After being attached to the surface, a coating material is supplied from the coating material supply unit on the lower side in the rice grain conveyance direction, and different types of coating materials are supplied from the plurality of coating material supply units into the stirring chamber forming member. By doing so, a plurality of types of coating materials can be deposited on the surface of the rice grain in a state where the respective coating materials are evenly adhered over the entire surface of the rice grain.
Therefore, a rice grain coating apparatus that can improve the manufacturing efficiency of processed rice in which a plurality of types of coating materials are stacked and adhered to the surface, and that can uniformly apply each of the plurality of types of coating materials over the entire surface of the rice grain. Can now be offered.

In addition to the first feature configuration, the second feature configuration is
The stirring chamber forming member includes a plurality of cylindrical stirring chamber forming bodies in a sideways posture, aligned in the rice grain conveying direction, and from the terminal portion of the stirring chamber forming body on the upper transport side in the adjacent stirring chamber forming bodies. Constructed to deliver rice grains to the starting end of the stirring chamber forming body on the lower conveyance side,
The helical rotating body is provided inside each of the plurality of stirring chamber forming bodies.

  That is, in a state where the rice grains are transported in the longitudinal direction in each stirring chamber forming body by a spiral rotating body, the end of the stirring chamber forming body on the upper transport side is moved to the start end of the stirring chamber forming body on the lower transport side. A plurality of coating material supply units distributed and arranged at different locations in the rice grain conveyance direction with respect to the rice grain group conveyed over the plurality of stirring chamber forming bodies arranged in the rice grain conveyance direction while being delivered Therefore, different types of coating materials are supplied into the stirring chamber forming body.

In other words, by providing a plurality of stirring chamber forming bodies as described above and configuring the stirring chamber forming member, it is possible to lengthen the transport path for transporting the rice grain group through the stirring chamber forming member. Since it becomes possible to lengthen the length of the section for conveying the rice grain group while stirring with the coating material supplied from the material supply unit, it is possible to adhere each coating material more evenly over the entire surface of the rice grain. It becomes possible.
In addition, since it becomes possible to disperse and dispose more coating material supply units at different locations in the rice grain conveyance direction of the stirring chamber forming member, in a state where each coating material is evenly attached over the entire surface of the rice grain, Many kinds of coating materials can be deposited on the surface of the rice grain.

Then, a plurality of stirring chamber forming bodies that are adjacent to each other in the rice grain conveying direction are arranged in parallel in a state where the start end portions are opposite to each other, or in a V shape having a crossing angle smaller than 90 ° in plan view. In such a configuration, a plurality of stirring chamber forming bodies are disposed by being disposed so as to be delivered from the terminal end portion of the stirring chamber forming body on the upper transport side to the starting end portion of the stirring chamber forming body on the lower transport side. It becomes possible to arrange | position, enabling reduction of size.
Accordingly, more types of coating materials can be deposited on the surface of the rice grain while being able to reduce the installation space of the apparatus and in a state where each coating material is evenly adhered to the entire surface of the rice grain. It became so.

In addition to the first or second feature configuration, the third feature configuration is
The helical rotator is provided with a stirring rotator that rotates around an axis along the longitudinal direction of the spiral rotator to stir the rice grains.

  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 rice grains are gathered to the bottom side in the stirring chamber forming member by the spiral conveying action part of the spiral rotator. Good by being agitated by the agitating rotator rotating inside the spiral rotator while being conveyed along the longitudinal direction of the agitating chamber forming member while moving inward and outward in the radial direction of the conveying action portion While being agitated, it is well conveyed along the longitudinal direction of the stirring chamber forming member.

That is, as the spiral rotating body rotates, the rice grain group moves inward and outward in the radial direction of the spiral conveying action portion as described above, and the length of the stirring chamber forming member is increased by the spiral conveying action portion. Since the rice grains are pushed and moved along the direction, the rice grains are pushed and moved along the longitudinal direction of the stirring chamber forming member while being sufficiently stirred by the movement of the spiral conveying action portion inside and outside in the radial direction. However, the rice grain group tends to flow in a layered state in a relatively gathered state on the bottom side of the stirring chamber forming member only by rotating the spiral rotating body in such a manner.
Therefore, by rotating the stirring rotator inside the spiral conveying action portion, by lifting and rotating a part of the rice grains that are flowing in layers on the bottom side of the stirring chamber forming member, etc. It is possible to positively disturb the rice grains that are flowing rapidly, and to further promote stirring of the rice grains.

Therefore, it becomes possible to adhere each coating | covering material more uniformly over the whole surface of a rice grain.
Further, when the coating material is supplied in the form of a solution, even if it is in a state where the coating material solution having a high concentration and a high viscosity is supplied and the rice particles are easily adhered to each other by the coating material solution, Since the inside of the stirring chamber forming member can be conveyed while stirring in a state in which the adhesion between each other is sufficiently suppressed, it becomes possible to evenly attach a high concentration coating material solution to the surface of each rice grain, Even when the surface of the grain of rice is coated with a relatively thick coating film to produce processed rice, the processed rice can be efficiently produced.

In addition to the third feature configuration, the fourth 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, the rice grains collected on the bottom side of the stirring chamber forming member are moved in the longitudinal direction of the stirring chamber forming member by the stirring rotating body extending in a rod shape from a position away from the rotational axis of the spiral rotating body. It is possible to efficiently lift and stir over a wide range, and to further promote stirring of the rice grains.

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 rice grains are different, it is possible to suppress the rice grains from being stressed by being sandwiched between the spiral rotator and the stirring rotator, so that damage to the rice grains can be suppressed. It becomes.
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, it is possible to more uniformly coat the entire surface of the rice grain while reducing the cost, and to suppress damage to the rice grain.

The fifth feature configuration is in addition to the first feature configuration,
The upper end of the spiral rotating body in the rice grain conveying direction is configured to be supported by the drive rotating unit,
The stirring rotator is formed in a U shape that is inverted on the lower side in the rice grain conveyance direction, and is provided in a cantilever state in which the upper end on the rice grain conveyance direction is supported by the drive rotation unit. It is characterized by.

  That is, the drive rotation part is provided on the upper side in the rice grain conveyance direction with respect to the stirring chamber forming member, and both the spiral rotator and the U-shaped agitation rotation body in the drive rotation part are superior in the rice grain conveyance direction. Since the side end portions are supported and provided in a cantilevered state, it is possible to simplify the configuration for driving and rotating the spiral 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 rice grain group can be stirred, stirring of the rice grain group can be further promoted.
Accordingly, the coating material can be more evenly deposited over the entire surface of the rice grain while further reducing the cost.

In addition to any of the first to fifth feature configurations described above, the sixth feature configuration is
A coating material supply unit for supplying a function-adding coating material that supplies a function-adding coating material that adds a function to rice grains as the coating material to the plurality of coating material supply units, and a function-adding coating material supply unit For mold release, which is located on the lower side of the rice grain conveying direction than the coating material supply unit and supplies as the coating material a release coating material that suppresses adhesion between the rice grains coated with the function-adding coating material It is characterized in that a coating material supply section for supplying a coating material is included.

  That is, a function-adding coating material for adding a function to rice grains is supplied from the coating material supply unit for supplying a function-adding coating material into the stirring chamber forming member, and the coating material supply unit for supplying the function-adding coating material The release coating material that suppresses adhesion between the rice grains coated with the function-adding coating material from the coating material supply section for supplying the release coating material at a position closer to the lower side of the rice grain transport direction than Since it is supplied into the stirring chamber forming member, it is possible to produce processed rice in which the release coating material is attached to the surface of the coating film of the function addition coating material.

That is, some function-adding coating materials are viscous and are caused by temperature change or moisture absorption after being attached to the surface of rice grains in a solution and dried.
Therefore, by attaching a functional coating material to the surface of the rice grain, and then attaching a release coating material, the adhesion between the rice grains is suppressed, and the processed rice in which the rice grain group is difficult to agglomerate is manufactured. Can do.
By the way, as a coating material for function addition, it can improve functions such as health and nutrition and improve health functions by having materials suitable for food, for example, suppressing increase in blood sugar level, lowering cholesterol, etc. Water-soluble dietary fiber that can be used (for example, indigestible dextrin) is used.
As the release coating material, a material having a release action and suitable for food, for example, sodium carboxymethyl cellulose is used.
Accordingly, it has become possible to efficiently produce processed rice which has functions such as nutrition and health, and which does not easily become massive.
