The stirring shaft 31, a stirring shaft driving device 41 for controlling and driving the stirring shaft 31 so that it can reversibly rotate, that is, can rotate forward and backward, and the device housing 11
And a steam generator 51 incorporated in the.

However, regarding the device housing 11,
The steam chamber 52 of the steam generator 51 including the outer peripheral surface of the body portion 21a is formed by interposing a required space between the steam chamber 52 and the cylindrical stirring cylinder 21. On the lower side, a water storage unit 5 that can appropriately supply water from the outside
2a and a heating device 53 by electric heating such as a required gas burner or sheath heater for heating the water stored in the water storage portion 52a to generate steam are arranged respectively.

Needless to say, it is possible to ensure the safety associated with.

Further, the upper side of the cylindrical stirring cylinder 21 is exposed above the apparatus housing 11 in order to supply the water-containing granular material to be treated which is the object of stirring and mixing and heating and drying. Supply port 23 with supply opening / closing lid 24 opened
And one end plate portion (in this case, the end plate portion on the left end side) 21b
And a discharge port 25 with a discharge opening / closing cover 26 for discharging the water-containing granular material to be treated, which has been stirred and mixed and heated and dried, to the outside, and the supply port 23 On one side (in this case, the back side), the exhaust port opened to the outside during drying, in other words, communicated with the inside of the cylindrical stirring cylinder 21 and opened to the outside An exhaust port portion 27 is formed.

In the paddles 32 arranged on the stirring shaft 31 in the cylindrical stirring drum 21, the tip end surface of the paddles 32 on the forward rotation direction side through the frame 32a of each paddle 32 is provided. , The paddle tip surface on the reverse rotation direction side through the frame portion 32a in each paddle 32 of the other portion is similarly set as the stirring surface 33a parallel to the rotation axis used for stirring and mixing the water-containing granular material to be treated. It is formed as an inclined discharge surface 33b used for transferring the water-containing particulates to the discharge port 25 side (see FIG. 3).

With respect to the paddle surface of each of these paddles 32, in this embodiment, a part of the paddle surface is a stirring surface 33a on the forward rotation side and the other is a discharge surface 33b on the reverse rotation side. However, regarding the paddle surface, for example, by using a member having a right-angled triangular cross section,
All of them are used as the stirring surface 33a (corresponding to the bottom surface of the right triangle) on the forward rotation direction side, and as the discharge surface 33b (also corresponding to the hypotenuse surface of the right triangle) on the reverse rotation direction side. This may be arbitrarily selected depending on, for example, the type and property of the granular material to be treated.

Further, as the stirring shaft driving device 41, for example, a reversible rotation motor 42 is used, and an output shaft 43 of the reversible rotation motor 42 can be similarly reversibly driven, for example, a deceleration interlocking mechanism, for example, a worm / worm wheel. Is connected to the stirring shaft 31 via a deceleration interlocking mechanism 44 such as by meshing with each other, and the reversible rotation motor 42 is normally rotated to drive the stirring shaft 31, and thus each paddle 32, to the positive rotation direction side, and By the reverse rotation, each paddle 32 can be rotationally driven in the reverse rotation direction side.

Therefore, in the apparatus of the above embodiment,
By holding the heating steam of the required temperature generated by the steam generator 51 in the steam chamber 52, the body portion 21a of the cylindrical stirring drum 21 is heated to a predetermined temperature from the outer peripheral surface side, and the stirring shaft drive device 41 is also provided. In this case, first, the reversible rotation motor 42 is rotated in the forward direction to rotate the stirring shaft 31 in the forward direction, that is, the paddles 32 are rotationally driven in the forward rotation direction side. A predetermined amount of the water-containing granular material to be treated is supplied from the portion 23 into the body portion 21a.

The water-containing granular material to be treated thus supplied is driven by the rotation of each paddle 32 in the forward rotation direction side. In the case of the rotation drive in the forward rotation direction side, each paddle 32 is driven. Since the paddle surface on the normal rotation direction side of is a stirring surface 33a parallel to the rotation axis, the water-containing granular material to be treated supplied here is the body portion 2 of the cylindrical stirring cylinder 21.
In addition to being stirred and mixed in 1a while being sufficiently rotated, the steam contained in the body portion 21a is used to dry and remove the water content of the water-containing particulate matter to be treated, and as a result, the water-containing matter to be treated as intended is obtained. The stirring and mixing process and the drying process can be performed on the granular material, and the water vaporized by the drying process is diffused to the outside from the exhaust port 27. In addition to the stirring and mixing action, the pulverizing action may be added to the water-containing granular material to be treated by the rotation of the paddle 32.

After the stirring and mixing treatment and the drying treatment of the water-containing granular material to be treated are completed as described above, the stirring shaft 31 is rotated in the reverse direction, that is, by the reverse rotation of the reversible rotation motor 42. By rotating and driving each paddle 32 in the reverse rotation direction side, in the case of rotationally driving in the reverse rotation direction side, the reverse rotation direction side paddle surface of each paddle 32 faces the discharge port 25 side. Since it is the discharge surface 33b, the water-containing granular material to be treated, which has been subjected to the stirring and mixing treatment and the drying treatment, is the cylindrical stirring cylinder 21.
While being stirred and mixed in the body portion 21a of the
It is transferred to the side, and as a result, it can be easily taken out from the discharge port 25.

In the structure of the above embodiment, the case where the drying treatment is performed together with the stirring and mixing treatment of the water-containing particulate matter to be treated has been described, but when the drying treatment is not required, that is, the treatment to be treated is carried out. In the case of performing only the stirring and mixing process on the granular material, it is sufficient to omit each component for the drying process here, or not to activate the drying process means. Even when performing only stirring and mixing processing for objects,
It can be easily applied.

In FIG. 4, in combination with an isosceles triangular paddle 32b, the frame portion 32a is provided in front of this (outlet side).
The paddle 32c in which one flat plate is attached by inclining to the outlet port 25 side by utilizing is shown. In this embodiment, one plate of the paddle 32c is inclined toward the discharge port portion 25 side, so that one surface becomes the discharge surface 33b and is inclined toward the discharge port portion 25 side, and the opposite surface is the stirring surface 33c. Then, the rear paddles 32b are inclined toward the stirring surface 33c side and face each other. As a result, when the stirring shaft 31 is rotated in the direction of the arrow a, the stirring surface 33 is rotated in the paddles 32b and 32c.
Since c is opposed to each other, a force that opposes the object to be processed acts on the object to be stirred well. on the other hand,
When the stirring shaft 31 is rotated in the direction of arrow b, the paddle 32
Since the discharge surface 33b of both b and 32c is inclined toward the discharge port 25 side, the water-containing particulate matter to be treated is sent to the discharge port 25 side. Although only one set of paddles 32b and 32c is shown in FIG.
A plurality of sets (rows) can be attached to the stirring shaft 31 depending on the size (length) of the.
