A drying device for drying the coated material solution to form a coating on the surface of the rice grains to be coated, the coating device comprising a cylindrical stirring chamber forming member in a sideways posture, and an inside of the stirring chamber forming member Agitating / conveying means for conveying the rice grains to be coated received from the rice grain receiving port into the stirring chamber forming member in the longitudinal direction of the stirring chamber forming member and discharging the rice grains from the rice grain outlet; The present invention relates to a washing-free rice production facility comprising a coating material solution supply means for supplying the coating material solution into a member.

  The washing-free rice production facility having the above-described structure produces the washing-free rice by forming a coating covering the surface of the rice grain by attaching the coating material solution to the coated rice grain from which all or most of the paste layer has been removed and drying it. Is for. And in such a no-wash rice manufacturing equipment, there existed what was comprised as follows conventionally.

  That is, the coating apparatus includes a rotating stirring conveyance body inside a cylindrical stirring chamber forming member in a sideways posture, and the rice grains to be coated received from one end side of the stirring chamber forming member are stored in the stirring chamber forming member. It is configured to stir while transporting toward the other end side, so that the coating material solution is adhered while transporting the rice grains, and dropped and discharged downward from the other end side of the stirring chamber forming member.

JP-A-9-181

  In the above conventional configuration, the adhered rice grains dropped and discharged from the rice grain discharge port of the coating apparatus are directly supplied into the horizontal cylinder of the drying apparatus, so that the adhered rice grains can be fed as quickly as possible, for example, by a screw conveyor. In addition, the transport distance can be shortened and supplied to the drying apparatus without performing transport by mechanical transport means such as a scraping type conveyor. In other words, the attached rice grains are in a state in which the rice grains to which the coating material solution is adhered tend to become clumped due to the adhesive force of the coating material solution, so that the drying treatment is not performed. When a long time elapses, there is a risk of sticking firmly in a lump. Moreover, even if the coating material can be applied substantially uniformly to the surface of the rice grains in the coating device, the coating material solution is peeled off and then the coating becomes non-uniform when the coating material is subsequently transported by a transport device such as a screw conveyor. There is a fear. Therefore, as described above, the adhered rice grains can be supplied to the drying device as soon as possible and with a shorter transfer distance without being transported by the transport device.

  By the way, in the equipment as described above, since the coating material solution is transported while being adhered to the rice grains to be coated inside the stirring chamber forming member of the coating apparatus, such a coating material attaching operation is executed. After that, a part of the coating material solution is attached to the inner surface of the stirring chamber forming member and the outer surface of the stirring and conveying means. If left as it is, for example, mold may be generated or germs may grow, which is not preferable for food hygiene. Therefore, at the end of the operation, the inner surface of the stirring chamber forming member, the stirring and conveying means, etc. in the coating apparatus are cleaned. There is a need.

  However, in the above conventional configuration, the coating device is provided in a fixed position above the drying device so as to overlap with the drying device in a state along the longitudinal direction of the horizontal cylinder of the drying device. When cleaning the inner surface of the agitating chamber forming member, the agitating / conveying means, and the like in the apparatus, when the parts are removed or disassembled for cleaning, it becomes difficult for the drying apparatus to interfere with the work. Further, not only such cleaning work, but also when performing work such as inspection and repair replacement of members, it is difficult to perform similarly.

  The present invention has been made paying attention to such a point, and the purpose thereof is as soon as possible, without carrying the adhered rice grains to which the coating material solution has been adhered, by mechanical conveying means. A washing-free rice production facility capable of facilitating maintenance work such as cleaning work and repair inspection work in the coating apparatus as described above, while allowing the transporting distance to be reduced and supplied to the drying apparatus. The point is to provide.

A first characteristic configuration of the present invention is a coating apparatus that generates a coated rice grain by attaching a coating material solution to a rice grain to be coated from which all or most of the paste powder layer has been removed, and the adhesion supplied from the coating apparatus.

It is installed as a working position in a state of projecting laterally outward of the drying device, and
By turning around a turning fulcrum located on the laterally outer side of the drying device, the working position and a maintenance position for allowing the entire stirring chamber forming member to protrude laterally outward of the drying device can be switched. It is in the point.

  According to the first characteristic configuration, the coating apparatus is in a state in which, in the working position, the one end portion in the longitudinal direction where the rice grain discharge port of the stirring chamber forming member is positioned overlaps the drying apparatus in plan view. The structure is such that the adhered rice grains dropped and discharged from the rice grain outlet of the coating apparatus are directly supplied to the inside of the drying apparatus, so that the adhered rice grains to which the coating material solution is adhered can be mechanically quickly and mechanically. It is possible to supply the drying apparatus with a shorter transport distance without performing transport by the transport means.

  Further, in the working position, the other end portion in the longitudinal direction where the rice grain receiving port is located in the stirring chamber forming member is in a state of projecting outward to the lateral side of the drying device, Since it is configured to be switchable between the working position and a maintenance position in which the entire stirring chamber forming member protrudes laterally outward of the drying device by turning around the turning support point, When carrying out maintenance work such as cleaning work and repair inspection work, switching to the maintenance position allows the coating device to be separated from the drying device, so that the work can be performed without disturbing the drying device. It can be easy to do.

  By the way, as a configuration for facilitating the maintenance work as described above, the coating apparatus is configured to slide the stirring chamber forming member at the work position along the longitudinal direction and switch to the maintenance position. Although it is conceivable, in the configuration in which the sliding movement is performed along the longitudinal direction in this way, there is a disadvantage that the configuration for supporting the stirring chamber forming member in a movable manner is complicated.

  On the other hand, according to the first characteristic configuration, the stirring chamber forming member can be moved freely because it is configured to switch between the work position and the maintenance position by turning around the turning fulcrum located on the laterally outer side of the drying device. The support structure can be simpler than the slide structure, and the moving operation can be easily performed as compared with the slide operation over a long distance.

When the door member is switched to the closed state in order to close the opening formed in the side wall portion of the drying device, the stirring chamber forming member is held at the working position by the door member in the closed state. When the stirring chamber forming member is switched to the maintenance position for maintenance work, if the door member is switched from the closed state to the open state, the holding of the stirring chamber forming member by the door member is released. The stirring chamber forming member can be swung around the turning fulcrum and switched to the maintenance position.

  Therefore, when performing maintenance work, it is only necessary to switch the door member to the open state and swing the stirring chamber forming member as it is. When the maintenance work is finished and switched to the working position, the stirring chamber forming member is swung. Since the door member only needs to be switched to the closed state after switching to the work position, the operation for holding the stirring chamber forming member and the operation for releasing it are unnecessary, and the maintenance work can be easily performed. In addition, there is no need for a dedicated holding means for holding the stirring chamber forming member in position, and the configuration can be made simpler than that provided with them.

  In addition to the first feature configuration or the second feature configuration, the third feature configuration of the present invention is characterized in that the work passage along the direction intersecting the longitudinal direction of the stirring chamber forming member at the work position is the swivel fulcrum position.
