Description

TECHNICAL FIELD The present invention relates to a drying apparatus, and more particularly to a drying apparatus used for drying powders and granules such as pharmaceuticals.

For example, in manufacturing in the fields of pharmaceuticals and fine chemicals, batch-type production, which controls each process such as washing, concentration, crystallization, filtration, and drying, has been the basis.
Such batch production has the following problems.
- Not only is the amount that can be processed each time is limited, but the work is complicated because it has to be processed once for each predetermined amount.
・In the case of batch production, products are processed and produced all at once, but it is difficult to adjust the production volume and respond flexibly to the production plan according to demand fluctuations, so the cost required for inventory stock is high. This is also an issue in terms of energy consumption.
・Because it is necessary for workers to be involved in each process, there is a risk of human error as well as a large amount of time loss.
・The product had to be moved to the next process after each process, and there was a risk that foreign matter such as dust and dirt would be mixed in during this process.
・As for the processing capacity, it may be possible to solve it by installing multiple units, but there were also issues such as securing the installation place.

In particular, pharmaceutical manufacturing requires strict manufacturing and quality control to ensure that products are manufactured safely and that a certain level of quality is maintained.・It is preferable to comply with quality control standards), and in order to achieve GMP, it is preferable to use continuous production in which processes such as washing, concentration, crystallization, filtration, and drying are performed continuously instead of conventional batch production. .
Therefore, the inventors of the present application worked on developing a drying apparatus suitable for this type of continuous production.

In Patent Document 1, a hollow disk-shaped drying plate portion fixedly arranged in multiple stages at predetermined intervals in the vertical direction in a casing, a rotary main shaft provided so as to pass through the center of the drying plate portion, and a rotating four scraping units that are synchronously mounted on the main shaft and slide on the upper surface of each drying plate unit arranged in multiple stages; means for supplying a heating medium to the hollow interior of the drying plate unit; and an inlet through which the powder (object to be dried) is sequentially introduced onto the uppermost drying plate portion by the supply mechanism, and the powder introduced onto the drying plate portion heated by the heating medium is fed to the drying plate portion. , scraping movement of the scraping portion in the central direction or the outer peripheral direction of the drying plate portion, and then sequentially dropping onto the lower drying plate portion. A vertical multi-stage drying apparatus is disclosed that performs continuous drying processing of powder by repeatedly and continuously performing the drying and scraping operations in the vertical direction.

According to such a continuous drying apparatus, it is possible to continuously dry powder in a wet state, so that the processing capacity is improved, there is no time loss, and contamination can be effectively prevented. can.

In the conventional continuous drying device, powder is supplied as a lump to one place on the uppermost drying plate from one powder supply mechanism, and heated while being scraped by the scraping unit. It moves on the drying plate part where it is. Then, it moves in the inner diameter direction or the outer diameter direction of the drying plate portion and falls from the inner diameter end edge or the outer diameter end edge onto the lower drying plate portion. Then, this process is repeated for the number of drying plate portions arranged in multiple stages to complete the drying process.

However, the lumpy powder, which is always dropped and supplied to the same place of the drying plate portion, is scraped off by the scraping portion and dropped onto the lower drying plate portion, but the dispersion effect is not so good. Therefore, it takes a long time to diffuse uniformly, which may result in insufficient drying or uneven drying.
In addition, if multiple powder supply mechanisms are installed, the powder can be supplied to multiple locations on the uppermost drying plate, and a slight dispersion effect may be expected, but the powder supply mechanism is expensive. Therefore, it will lead to a rise in costs. Even if a plurality of units are to be installed, two units are the limit in terms of cost and space. Therefore, even if the number of powder supply mechanisms is increased to two units, a great dispersion effect cannot be expected.
Furthermore, in the continuous drying device disclosed in Patent Document 1, since the powder supply mechanism is arranged vertically above the rotating main shaft, the powder fed from the powder supply mechanism is not applied to the scraping part. It may fall on the scraping part and adhere to the scraping part. There was a possibility of causing deterioration and a decrease in yield.

That is, the annular plate portion upper surface region 25 located between the wall portion 23 on the inner diameter side and the wall portion 24 on the outer diameter side is an input region for the drying medium, and the drying medium is guided by the respective dispersion guide portions 27. area.

The rotary plate portion 20 is dropped in a predetermined area on the inner diameter side, for example, in this embodiment, a predetermined length (rotational direction length) and a predetermined width (radial direction width of the rotary plate portion 20) at intervals of 90 degrees. Four holes 26 are formed. In the drawing, an arrow R1 indicates the rotation direction of the rotary plate portion 20, and an arrow W1 indicates the radial width of the rotary plate portion 20. As shown in FIG.

The drop hole portions 26 are formed on the inner diameter side of the rotating plate portion 20 at predetermined intervals. A region between the portion 22 is bored with a predetermined length.
Note that the drop hole portion 26 of the present embodiment will be described as having a configuration in which the wall portion 23 on the inner diameter side is left open, but the wall portion 23 is cut away to form a so-called notched hole portion. are also well within the scope of the present invention.

Further, in the rotating plate portion 20, each drop hole portion 26 is located at each scraping guide portion 18 (first scraping guide portion 18a) constituting the uppermost drying portion 10 (first drying portion 10a). It is attached and fixed to the main shaft 8 (for example, 4).

Since the rotating plate portion 20 and the scraping guide portion 18 are attached and fixed to the same main shaft 8 so as to rotate in synchronism, the drop hole portion 26 and the scraping guide portion 18 are always in contact with each other. It is preferably designed to avoid coming into overlapping positions.
When the drop hole portion 26 and the scraping guide portion 18 are arranged at a position where the drop hole portion 26 and the scraping guide portion 18 overlap, the dry medium dropping from the drop hole portion 26 falls onto the scrape guide portion 18 and is placed on the scrape guide portion 18 . It is conceivable that it will remain untouched. In this way, even if there is a medium on the scraping guide section 18 that is not dried, if the medium falls after a certain period of time, it passes over the heating plate as usual and is dried. If it stays on the top for a long time, there may be risks such as deterioration over time, poor drying due to clumping, and deterioration of traceability due to impaired plug flowability.
Therefore, a configuration like this embodiment is adopted.

In the present embodiment, the number of drop holes 26 provided is the same as the number of dispersion guide portions 27 provided, but the number of each provided is arbitrary, and the number of drop holes 26 is set on the rotating plate portion 20. When the dried medium is finely dispersed and dropped onto the drying plate portion 11 below, it is possible to increase the number of the drop holes 26 and the number of the dispersion guide portions 27 within the scope of the present invention. be.

In the present embodiment, the dispersed guide portions 27 are provided with four dispersed guide portions 27 from a first dispersed guide portion 27a to a fourth dispersed guide portion 27d at predetermined intervals. Further, the respective dispersion guide portions 27 have different lengths in the radial direction of the rotary plate portion 20 .
In the present embodiment, the first dispersion guiding portion 27 a to the fourth dispersion guiding portion 27 d are arranged within the passage locus range of the drying medium supplied onto the rotating plate 20 from the drying medium receiving portion 33 . The first dispersion guide portion 27a to the fourth dispersion guide portion 27d are formed in an elongated shape in which the other end side extends in the outer diameter direction of the rotary plate portion 20 from the dispersion guide portion on the upstream side in order.

The dispersion guiding portion 27 includes a first portion (curving portion) 28 formed in a substantially U-shape in plan view in the vertical direction, and one end portion of the first portion (curving portion) 28 extending along the outer diameter of the rotating plate portion 20 . It is composed of a second part (induction blade part) 29 elongated in the direction, and is formed in the shape of a metal blade having a predetermined height from the lower surface to the upper surface. Also, the first portion (curving portion) 28 is arranged so as to be positioned above the drop hole portion 26 that has been moved by the rotating motion of the rotating plate portion 20 (see FIG. 4, for example).
In the present embodiment, the dispersion guide portions 27 guide the drying medium on the drying plate portion 11 toward the inner diameter direction. ) on the upper surface of the rotating plate portion 20 located upstream in the rotational direction from the second portion (guiding blade portion) 29 of the second portion (guiding blade portion) 29, and the guiding surface portion of each second portion (guiding blade portion) 29. are arranged in an inclined manner so that each angle formed by intersecting with is an acute angle (see, for example, FIG. 4).

The lower surface of the dispersion guiding portion 27 facing the plate portion upper surface region 25 of the rotating plate portion 20 forms a very small gap with the plate portion upper surface region 25 of the rotating plate portion 20, and is suspended and supported by the blade holding portion 30. It is The lower end side of the blade holding portion 30 is integrally connected and fixed across the upper surface of the free end of the first portion (curving portion) 28 and the upper surface of the second portion (guiding blade portion) 29 in the dispersion guiding portion 27. .

The first dispersion guide portion 27 a closest to the dry medium receiving portion 33 is provided in the dry medium passage area of the dry medium receiving portion 33 positioned closer to the inner diameter of the rotary plate portion 20 so that at least the second portion (guiding blade portion) 29 is free. The end side 29a is configured to be located (see, eg, FIGS. 4, 6 and 7).

The second dispersion guide portion 27b arranged on the downstream side of the first dispersion guide portion 27a has a substantially U-shaped first portion 28 in plan view and a first portion It is composed of a second portion (guiding blade portion) 29 formed by extending one end of a (curving portion) 28 in a long shape, and the length of the second portion (guiding blade portion) 29 is The second portion (guiding blade portion) 29 of the first dispersion guiding portion 27a is formed in an elongated shape positioned (extending) in the outer diameter direction of the rotary plate portion 20 (for example, FIG. 4, FIG. 6 and Figure 7).
In this manner, the other end side (free end side of the second portion 29) 29a of the dispersion guide portion 27 on the upstream side is positioned (extended) in the outer diameter direction of the rotary plate portion 20, and is elongated. In this embodiment, the fourth dispersion guide portion 27d is formed in the longest shape, and the other end side (free end side of the second portion 29) 29a is located on the outer diameter side of the rotary plate portion 20. It is positioned (extended) to the vicinity of the provided wall portion 24 (for example, see FIGS. 4, 6 and 7).

The drying medium input part 32 is configured in a cylindrical shape suspended inside the casing 2 from the outside of the top plate part 4 of the casing 2, and is integrally configured at its lower end so as to surround the periphery of the lower end. It includes a dry medium receiving portion 33 that receives the dry medium input from the input portion 32 and guides it onto the rotating plate portion 20 (see, for example, FIG. 5).
In the present embodiment, the dry medium receiving section 33 is formed separately from the dry medium input section 32, and is integrally attached and fixed to the lower end of the dry medium input section 32. It may optionally be molded integrally with the lower end of the portion 32 .

The dry medium receiving portion 33 constitutes a scattering prevention portion 34 that inhibits scattering of the introduced drying medium and a part of the scattering prevention portion 34, and has a predetermined height between the rotary plate portion 20 and the drying medium through which the drying medium can pass. and a vertically movable leveling gate portion 35 capable of forming a narrow passage area 36 (see, for example, FIG. 5).

The scattering prevention portion 34 has a peripheral wall portion configured to surround the lower end inlet of the drying medium inlet portion 32, and the leveling gate portion 35 is provided on the downstream side of the rotary plate portion 20 in the rotation direction. constitutes a part of the scattering prevention unit 34 .
By providing the scattering prevention unit 34 as in the present embodiment, it is possible to prevent the drying medium from scattering (dropping) out of the apparatus, so useful effects such as improvement of yield and reduction of labor for cleaning the work area can be achieved. can be effective.

The leveling gate portion 35 is configured to be vertically movable.
For example, in the present embodiment, a shaft 35b is provided together with the drying medium input unit 32, and is rotated by the rotation of the operation handle 35a. A vertically moving body 35c, a connecting operation portion 35d vertically installed by integrally connecting an upper end side to the vertically moving body 35c, and a lower end side of the connecting operation portion 35d are integrally connected to rotate the rotating plate portion 20 in the rotation direction R1. and a gate plate portion 35e which is positioned downstream of and constitutes a part of the scattering prevention portion 34 (see, for example, FIG. 5).

With such a configuration, by rotating the operation handle 35a, the gate plate portion 35e is moved vertically, and the gap between the lower end of the gate plate portion 35e and the upper surface of the rotating plate portion 20 is closed. That is, the width of the drying medium passage area 36 is adjusted. The drying medium passing area 36 can be changed in design so as to be an optimum passing area within the scope of the present invention depending on the processing speed, the type of drying medium to be processed, the wet state, and the like. For example, if the processing speed is high, it is conceivable that the drying medium will stagnate in the drying medium input section 32, so the drying medium passage area 36 should be widened.

"Explanation of operation of this device"
First, a predetermined amount of dry medium is introduced from the dry medium introduction section 32 onto the rotating plate section 20 of the dry medium distribution section 19 . Since the drying medium is once put into the drying medium receiving section 33, scattering of the drying medium to the outside is prevented (see, for example, FIG. 6A).
FIG. 8 shows the drying medium supply range A3 on the rotating plate portion 20 by hatching. That is, in the case of the present embodiment, for example, it is assumed that the drying medium supply timing is within the range (region) indicated by hatching A3.

The drying medium introduced into the plate portion upper surface region 25 of the rotary plate portion 20 by the rotating operation of the rotary plate portion 20 is passed through the dry medium passing region 36 adjusted by the vertical movement operation of the gate plate portion 35e of the leveling gate portion 35. , and move in the direction of rotation R1 sequentially in a state of being flattened to a predetermined height (see, for example, FIG. 6A).

A portion of the drying medium moving in the rotational direction R1 first hits the plate surface of the second portion (guiding blade portion) 29 of the first dispersion guiding portion 27a. As the rotary plate portion 20 continues to rotate, the dry medium that hits the second portion (guiding blade portion) 29 moves along the plate surface of the second portion (guiding blade portion) 29 toward the inner diameter of the rotary plate portion 20. and is induced.
Then, the drying medium guided in the inner diameter direction passes through the drop hole portion 26 that has been moved by the movement of the rotary plate portion 20 from the substantially U-shaped first portion (curved portion) 28, and passes through the uppermost first drying portion. It falls while being dispersed sequentially onto the first drying plate portion 11a (on the heat transfer surface) in 10a (see, for example, FIGS. 6(b) and 7(a)).

Furthermore, the drying medium that does not get caught on the second portion (guiding blade portion) 29 of the first dispersion guiding portion 27a and moves in the rotational direction R1 by the rotating operation of the rotary plate portion 20 is disposed next to the second Part of it hits the plate surface of the second part (guiding blade part) 29 of the dispersion guiding part 27b, and the rotating plate part 20 continues to rotate, so that the drying that hits the second part (guiding blade part) 29 The medium is guided in the inner diameter direction of the rotating plate portion 20 along the plate surface of the second portion (guiding blade portion) 29 .
Then, the drying medium guided in the inner diameter direction passes through the drop hole portion 26 that has been moved by the movement of the rotary plate portion 20 from the substantially U-shaped first portion (curved portion) 28, and passes through the uppermost first drying portion. It falls while being dispersed sequentially onto the first drying plate portion 11a (on the heat transfer surface) in 10a (see, for example, FIGS. 6(c), 6(d) and 7(b)).

Furthermore, the dry medium that does not get caught on the second portion (guiding blade portion) 29 of the second dispersion guiding portion 27b and moves in the rotational direction due to the rotation of the rotary plate portion 20 is transferred to the third A portion of the dry medium collides with the plate surface of the second portion (guiding blade portion) 29 of the dispersion guiding portion 27c, and the rotary plate portion 20 continues to rotate and hits the second portion (guiding blade portion) 29. is guided along the plate surface of the second portion (guiding blade portion) 29 in the radial direction of the rotating plate portion 20 .
Then, the drying medium guided in the inner diameter direction passes through the drop hole portion 26 that has been moved by the movement of the rotary plate portion 20 from the substantially U-shaped first portion (curved portion) 28, and passes through the uppermost first drying portion. It falls while being dispersed sequentially onto the first drying plate portion 11a (on the heat transfer surface) in 10a (see, for example, FIGS. 6(e), 6(f) and 7(c)).

Finally, the remaining dry medium that has moved in the rotational direction due to the rotation of the rotary plate portion 20 without being caught by the second portion (guiding blade portion) 29 of the third dispersion guiding portion 27c is disposed next. The second portion (guiding blade portion) 29 of the fourth dispersion guiding portion 27d that is in contact with the surface of the second portion (guiding blade portion) 29, and the rotating plate portion 20 continues to rotate, so that the dry medium that hits the second portion 29 It is guided in the radial direction of the rotary plate portion 20 along the plate surface of the (guiding blade portion) 29 .
Then, the drying medium guided in the inner diameter direction passes through the drop hole portion 26 that has been moved by the movement of the rotary plate portion 20 from the substantially U-shaped first portion (curved portion) 28, and passes through the uppermost first drying portion. It falls while being dispersed sequentially onto the first drying plate portion 11a (on the heat transfer surface) in 10a (see, for example, FIGS. 6(g), 6(h) and 7(d)).
Therefore, the drying medium that has fallen onto the drying plate portion 11 does not form a single large mass and falls in one place as in the conventional technology, but can be dispersed at different dropping positions. When the drying process is performed on the drying plate portion 11 which is heated by the heat medium flowing into the portion 12, there is no variation in the drying state and the occurrence of poor drying is reduced.

The drying medium dispersed and dropped on the drying plate portion 11 of the first drying portion 10a is dried on the drying plate portion 11 (on the heat transfer surface) heated to a predetermined temperature, and synchronized with the rotating plate portion 20. The blades 181 of the first scraping guiding portions 18a, 18a, 18a, and 18a are guided in the outer diameter direction of the drying plate portion 11, and from the outer diameter side of the drying plate portion 11, , onto the drying plate portion 11 of the second drying portion 10b located below.
The drying medium dropped onto the drying plate portion 11 of the second drying portion 10b is then moved in the radial direction of the drying plate portion 11 by the blade portions 181 of the second scraping guide portions 18b, 18b, 18b, and 18b. Guided and guided, it drops onto the drying plate portion 11 (on the heat transfer surface) of the third drying portion 10c located below through the drying medium drop hole portion 110 on the inner diameter side of the drying plate portion 11 .
Such an operation is repeated in the third drying section 10c, the fourth drying section 10d, and the fifth drying section 10e, and from the outer diameter side of the fifth drying plate section 11e of the fifth drying section 10e, the The drying medium dropped onto the sixth drying plate portion 11f (on the heat transfer surface) of the sixth drying portion 10f is guided in the inner diameter direction of the sixth drying plate portion 11f by the sixth scraping guide portion 18f. The drying medium is guided and discharged outward through the discharging portion 6 of the bottom plate portion 5 from the chute 17 which is vertically provided continuously to the drying medium drop hole portion 110 of the inner diameter of the sixth drying plate portion 11f.
A series of schematic flows of these drying media are indicated by arrows in FIG.
Specifically, the drying medium on the drying plate portion 11 rotates in the circumferential direction and also moves in a spiral shape in the circumferential direction, so that an arrow shown in FIG. fall in the direction of

In this embodiment, the drying medium is distributed and dropped from the inner diameter side of the rotating plate portion 20 onto the uppermost drying plate portion 11 (the first drying plate portion 11a in this embodiment) located below it. However, the drying medium is scattered and dropped onto the uppermost drying plate portion 11 (the first drying plate portion 11a in this embodiment) positioned below from the outer diameter side of the rotating plate portion 20. is also possible and within the scope of the present invention. In this case, each dispersion guiding portion 27 is arranged at an obtuse angle with respect to the circumferential virtual line V1 on the upper surface of the rotating plate portion 20 in order to guide the dry medium on the rotating plate portion 20 toward the outer diameter direction. do.

Figures 9 and 10 show an embodiment incorporating the blade portion 181 of another embodiment.

The blade portion 181 in the embodiment shown in FIGS. 9 and 10 is assumed to consist of a plurality of short (strip-shaped) blades 181a. In this embodiment, a plurality of strip-shaped blade portions 181a are arranged on the arm portion 180 at predetermined intervals and at a predetermined inclination angle. The strip-shaped blade portion 181 a is formed in a rectangular flat plate shape and arranged on the drying plate portion 11 .
Further, in this embodiment, the strip-shaped blade portion 181a is detachable from the arm portion 180, and the arrangement inclination angle is also adjustable.

For example, each of the strip-shaped blades 181a of the first scraping guide portion 18a, the third scraping guide portion 18c, and the fifth scraping guide portion 18e has one end attached to the arm portion 180 and the other end thereof. are disposed so as to be inclined toward the outer diameter direction of the drying plate portion 10a.
Specifically, the arm portions 180 of the first scraping guide portion 18a, the third scraping guide portion 18c, and the fifth scraping guide portion 18e, and the scraping of the strip-shaped blade portions 181a It is arranged in an inclined manner so that the angle a1 formed by intersecting with the surface 181b is an acute angle (see FIG. 11(a)). An arrow R2 in the drawing indicates the rotation direction of each strip-shaped blade 181a of the first scraping guide portion 18a, the third scraping guide portion 18c, and the fifth scraping guide portion 18e.

Further, for example, each of the strip-shaped blades 181a of the second scraping guide portion 18b, the fourth scraping guide portion 18d, and the sixth scraping guide portion 18f has one end side attached to the arm portion 180 and the other scraping guide portion 181a. The end side is arranged so as to be slanted toward the inner diameter direction of the drying plate portion 10a.
Specifically, the arm portions 180 of the second scraping guide portion 18b, the fourth scraping guide portion 18d, and the sixth scraping guide portion 18f, and the scraping of the strip-shaped blade portions 181a It is arranged in an inclined manner so that the angle a2 formed by intersecting with the surface 181b is an acute angle (see FIG. 11(b)). An arrow R2 in the drawing indicates the rotation direction of each strip-shaped blade 181a of the second scraping guide portion 18b, the fourth scraping guide portion 18d, and the sixth scraping guide portion 18f.

The operation in this other embodiment is the same as in the above embodiment. The scraping surfaces 181b of the strip-shaped blades 181a of the first scraping guide portions 18a, 18a, 18a, and 18a are being dried (on the heat transfer surface) and rotating in synchronization with the rotary plate portion 20. are sequentially guided in the outer diameter direction of the drying plate portion 11, and fall from the outer diameter side of the drying plate portion 11 onto the drying plate portion 11 of the second drying portion 10b located below (Fig. 9 , see FIGS. 10 and 11(a)).
Then, the drying medium dropped onto the drying plate portion 11 of the second drying portion 10b is transferred to the scraping surfaces 181b of the strip-shaped blade portions 181a of the second scraping guide portions 18b, 18b, 18b, and 18b. along the inner diameter direction of the drying plate portion 11, and the drying of the third drying portion 10c located below via the drying medium drop hole portion 110 (see FIG. 9) on the inner diameter side of the drying plate portion 11. It drops onto the plate portion 11 (see FIGS. 9, 10 and 11(b)). This operation is alternately repeated from the third drying section 10c to the sixth drying section 10f, and the dry medium that has been dried is discharged from the drying medium drop hole section 110 of the sixth drying section 10f through the shooter 17 and the discharge section 6. It is guided to the outside of the device (see FIG. 9).
The shape of the strip-shaped blade portion 181a, the number of strip-shaped blades 181a, the arrangement interval, the inclination angle, etc. can be changed within the scope of the present invention according to the specifications.
"Second embodiment"

FIG. 12 is a schematic diagram showing the essential parts of the second embodiment of the present invention, in which the dry medium dispersing section 19 has a configuration different from that of the first embodiment. Since other configurations and effects are the same as those of the first embodiment, only the main part of the present embodiment will be described in detail below, and the description of the other configurations and effects will refer to the first embodiment.

The dry medium dispersion section 19 differs from the first embodiment in the configuration of the rotating plate section 20 . The form of the dispersion guide portion 27 and the inclined arrangement state with respect to the rotary plate portion 20 are the same as those of the first embodiment.

Unlike the first embodiment, the rotating plate portion 20 of the present embodiment does not have the wall portion 23 on the inner diameter side, and the drop hole portion 26 is not provided.
In the present embodiment, the inner diameter of the rotating plate portion 20 is widened in the outer diameter direction by the radial width of the drop hole portion 26 of the first embodiment. For example, in the present embodiment, the inner diameter of the rotary plate portion 20 is widened to such an extent that the surface portion of the dry medium receiving portion 33 near the inner diameter of the rotary plate portion 20 is positioned substantially on the same level as the inner diameter end of the rotary plate portion 20 in the vertical direction. (larger diameter).
In this embodiment, the first portion (curved portion) 28 of the dispersion guiding portion 27 is arranged to protrude from the inner diameter of the rotating plate portion 20 above the area of the central through-hole portion 21 .
That is, the drying medium moved by the rotation of the rotary plate portion 20 is caught by the second portion (guiding blade portion) 29 and guided along the second portion 29 toward the first portion (curving portion) 28. When it comes down, it falls through the central through-hole portion 21 provided on the inner diameter side of the rotating plate portion 20 onto the first drying plate portion 11a of the first drying portion 10a below. The degree of projection of the dispersion guiding portion 27 into the area of the central through-hole portion 21 is not particularly limited.

In the case of the configuration of this embodiment, a control mechanism (phase detection mechanism) 90 is provided to detect the rotation phase of the main shaft 8 and control the drying medium to be intermittently supplied at predetermined intervals. preferable. Specifically, for example, a phase detection mechanism 90 comprising a proximity switch target 91 provided on the spindle 8 and a proximity switch 93 provided at a predetermined position facing each other is employed (see FIGS. 3 and 9). ).
That is, in the case of the present embodiment, when the drying medium is continuously supplied, the drying medium is deposited on the upper surfaces of the first scraping guide portions 18a, 18a, 18a, and 18a of the first drying section 10a and the upper surfaces of the connecting portions 22. is likely to fall. Therefore, the rotation phase of the main shaft 8 to which the first scraping guide portions 18a, 18a, 18a, 18a of the first drying section 10a and the connecting portions 22 are connected is detected via the phase detection mechanism 90. Control is performed so that the drying medium is intermittently supplied from the drying medium input section 3 .
Since the main shaft 8, the rotating plate portion 20, the first scraping guide portion 18a, and the connecting portion 22 are synchronized, the rotation speed of the main shaft 8 is taken into consideration, and the first scraping guide portion 18a and the connecting portion 22 It is preferable to intermittently control the supply interval of the drying medium so that the drying medium can be dropped from the space area between them.
The phase detection mechanism 90 is not particularly limited. means to intermittently supply the drying medium from the drying medium feeding unit 3 at predetermined intervals.
FIG. 13 shows the drying medium supply range A3 on the rotating plate portion 20 by hatching. Assuming that the drying medium supply range A3 is hatched in this manner, the rotating plate portion 20, the first scraping guide portion 18a, and the connecting portion 22 rotate and move synchronously, so that the drying medium falls on them. , does not occur. That is, in the case of the present embodiment, for example, it is assumed that the drying medium supply timing is within the range (region) indicated by hatching A3.
"Third Embodiment"

FIG. 14 is a schematic diagram showing the essential parts of the third embodiment of the present invention, in which the dry medium dispersing section 19 has a configuration different from that of the first and second embodiments. Other configurations and effects are the same as those of the first embodiment and the second embodiment. Embodiments are incorporated.

The dry medium dispersing section 19 is the same as that of the second embodiment in terms of the configuration of the rotary plate section 20, but the form of the dispersion guiding section 27 is different.

Unlike the first embodiment and the second embodiment, the dispersion guide part 27 of the present embodiment does not have the substantially U-shaped first part (curved part) 28 in plan view, and has a predetermined length. It is formed in the shape of a straight flat plate. The inclined arrangement state with respect to the rotary plate portion 20 is the same as in the first embodiment and the second embodiment.
In the present embodiment, one end 28 a of the linear plate-like dispersion guide portion 27 is arranged to protrude slightly from the inner diameter of the rotary plate portion 20 above the central through-hole portion 21 area. That is, when the dry medium moving on the rotary plate portion 20 is caught by the other end 29b of the straight plate-like dispersion guide portion 27 and guided in the inner diameter direction of the rotary plate portion 20, the rotary plate portion 20 It is configured to drop onto the first drying plate portion 11a of the first drying portion 10a below via the central through-hole portion 21 from the inner diameter side. The degree of projection of the dispersion guiding portion 27 into the area of the central through-hole portion 21 is not particularly limited.
In addition, in this embodiment, it is also possible to adopt the form of the rotating plate portion 20 in which the drop hole portion 26 is provided on the inner diameter side adopted in the first embodiment, and this is within the scope of the present invention.

Also in this embodiment, as in the second embodiment, a control mechanism (phase detection mechanism) that detects the rotation phase of the main shaft 8 and controls the drying medium to be intermittently supplied at predetermined intervals (phase detection mechanism). mechanism) 90 is preferably provided.
"Fourth Embodiment"

FIG. 15 is a schematic diagram showing a main part of a fourth embodiment of the present invention, and has a configuration different from that of the first to third embodiments in the dry medium dispersing section 19. As shown in FIG. Since the other configurations and effects are the same as those of the first to third embodiments, only the essential parts of this embodiment will be described in detail below, and the other configurations will be described in the first to third embodiments. Embodiments are incorporated.

The dry medium dispersing section 19 is the same as those of the second embodiment and the third embodiment in terms of the configuration of the rotary plate section 20, but the form of the dispersion guiding section 27 is different.

The dispersion guiding portion 27 of this embodiment is formed in the shape of a continuous single spiral blade whose diameter is gradually reduced. The vertical height of the blades is uniform in this embodiment. Specifically, the one end side 37 is connected to a position near the outer diameter of the dry medium passage area 36 in the dry medium receiving portion 33, and the width direction distance from the inner diameter of the rotary plate portion 20 is gradually reduced while the other end side is connected. 38 is connected to a position closer to the inner diameter of the dry medium passage area 36 in the dry medium receiver 33 .

When the drying medium that has moved on the rotating plate portion 20 is guided in the direction of the inner diameter of the rotating plate portion 20 along the spiral dispersion guiding portion 27, the inner diameters of the dispersion guiding portion 27 and the rotating plate portion 20 are guided. Since the width direction distance between the It is configured such that all the drying medium drops gradually and reaches the other end side 38 of the dispersion guide portion 27 . That is, while the rotating plate portion 20 makes one turn, the particles can be dispersed and dropped little by little in the circumferential direction on the first drying plate portion 11a, so that the dispersion efficiency is high.

In addition, in the case of this embodiment, there is also a possibility that the drying medium may fall onto the first scraping guide portions 18a, 18a, 18a, 18a and the connecting portions 22 of the first drying portion 10a. Therefore, it is preferable to employ a configuration in which the drying medium dropped onto the first scraping guide portions 18 a , 18 a , 18 a , 18 a and each connecting portion 22 is guided onto the drying plate portion 11 . For example, the arms 180 of the first scraping guide parts 18a, 18a, 18a, 18a and the connecting parts 22 are subjected to a surface treatment with excellent slipperiness, so that the drying medium that has fallen can be removed. It is possible to employ a configuration in which the ink slides onto the drying plate 11 without being fixed. Further, the upper surface of each arm portion 180 of the first scraping guide portions 18a, 18a, 18a, 18a is tapered downward, and the drying medium that has fallen is directed onto the drying plate portion 11 via the inclined surface. A configuration such as guidance can also be adopted.
