  The casing 24 is formed by connecting a cylindrical portion 24b to a truncated cone-shaped portion 24a having a large diameter at the upper end and a lower end having a small diameter. The upper end is sealed with a lid 25. The lid 25 has a loading port 26, and this loading port 26 is connected to a dropping port 15 provided in the transfer means 3. The lower end of the housing 24 is open and constitutes a discharge port 23.

  The scattering means 21 includes a scattering blade 27 and a second driving unit 28 that is a driving unit that applies a rotational force to the scattering blade 27. The scattering blade 27 includes a disk 29 and ridges 30 provided radially on the surface of the disk 29. The disk 29 is integrally connected to the distal end of the shaft 31 at the center of the back surface not having the ridges 30, and the shaft 31 is connected to the second drive unit 28 at the proximal end. The scattering means 21 is disposed such that the surface of the scattering blade 27 faces the drop opening 15 and is fixed to the inner surface of the housing 24 by the fixing means 32 below.

The spray port 37a is installed in a direction facing the disk 29. In this manner, the nozzle 37 sprays the amount of water adjusted by the water amount adjusting means 36 in the form of a mist in the housing 24.

  Next, the operation of the above configuration will be described. The raw material stored in the hopper 2 reaches one end of the raw material supply pipe 11 through the connecting portion 6. In this state, the first drive unit 13 and the second drive unit 28 are driven. The connecting part 16 is rotated by the first driving part 13. When the connecting portion 16 rotates, the screw conveyor 12 rotates. When the screw conveyor 12 rotates, the raw material at one end of the raw material supply pipe 11 is sent out by the screw 12a and reaches the dropping port 15 at the other end. The raw material that has reached the dropping port 15 of the raw material supply pipe 11 is dropped by its own weight from the charging port 26 connected to the dropping port 15 into the water adding device 1. The dropped raw material falls on the surface of the scattering blade 27 rotated by the second drive unit 28. The raw material 41 that has fallen on the surface of the scattering blade 27 is given a centrifugal force by the ridges 30 and is scattered to the upper part of the housing 24. At the same time, the adjusted amount of water is sprayed from the nozzle 37. When water is sprayed, water adheres to the scattered raw material 41. The raw material 41a to which water is attached falls downward due to its own weight as the weight increases. The dropped raw material 41a is discharged from the discharge port 23 in a watered state. The moisture added to the raw material 41 is adjusted by the rotational speed of the first drive unit 13, that is, the supply amount of the raw material and the amount of water sprayed from the nozzle 37. It is necessary to change the amount of water added to the raw material according to the raw material and the type of product produced from the raw material, and the amount of water added to the raw material is adjusted by the supply amount of the raw material and the amount of water.

  As described above, this embodiment corresponds to claim 1 and is provided with a hopper 2 for supplying a raw material such as rice flour, a transfer means 3 for transferring the raw material from the hopper 2, and a lower part of the transfer means 3. The hydration means 4 is hydrated to the raw material dropped from the transfer means 3, and the hydration means 4 includes the scattering means 21 for scattering the raw material and the spraying means 22 for hydrating the scattered raw material. Since the raw material is supplied, the supplied raw material is dropped into the hydration means 4 by the transfer means 3, and the dropped raw material is hydrated, so that hydration of the raw material can be continuously performed.

  Corresponding to claim 2, the hydrating means 4 is provided with the scattering means 21 and the spraying means 22 on the upper side and has an outlet 23 for discharging the hydrated raw material 41a on the lower side. Since the raw material 41a is discharged from the discharge port 23 provided below, the watered raw material 41a can be taken out without stopping the water addition apparatus 1.

  Corresponding to claim 3, the transfer means 3 comprises a raw material supply pipe 11 connecting the hopper 2 and the hydration means 4, and a screw conveyor 12 installed in the raw material supply pipe 11. From the above, since the supply amount of the raw material dropped on the hydration means 4 can be adjusted by the screw conveyor 12, the amount of the raw material to be hydrotreated can be appropriately changed, and the amount of water added to the raw material can be selectively changed.

  Further, corresponding to claim 4, the scattering means 21 includes a scattering blade 27 and a drive unit 28 that applies a rotational force to the scattering blade 27, so that the raw material dropped by the rotating scattering blade 27 is scattered. Since the hydrated raw material is dropped and discharged by its own weight, it can be continuously processed and can be hydrated into the raw material in a short time, thereby improving the efficiency.

  Corresponding to claim 5, the spray means 22 sprays the water amount adjusting means 36 for adjusting the water added to the raw material to a predetermined amount, and the predetermined amount of water adjusted by the water amount adjusting means 36. Since it consists of the nozzle 37, water is sprayed and adhered to the scattered raw material in a mist form, so that it can be added to the whole raw material without any unevenness and the processing time can be shortened. Depending on the type of product, the amount of water added to the raw material can be selectively changed and can be used for many purposes.
