Description

  The present invention relates to a rotary processing apparatus that performs a predetermined process on a workpiece while rotating.

  Conventionally, there is a pulverizing and pulverizing apparatus in which a beater member having a plurality of blades extending radially and a rolling shaft extending in the longitudinal direction (rotational axis direction) of the cylindrical body are arranged in a rotatable cylindrical body ( For example, see Patent Document 1). In this crushing and pulverizing and sizing apparatus, while rotating the beater member according to the rotation of the cylindrical body, and moving the rolling shaft within the cylindrical body, with respect to the object to be processed such as solid matter and fluidity, A crushing process, a crushing process, and a sizing process are performed. This will be specifically described below.

  The beater member is arranged separately from the cylindrical body, and each blade piece of the beater member collides with the inner wall of the cylindrical body according to the rotation of the cylindrical body. As a result, the beater member rotates within the cylindrical body. Then, due to the impact when each blade piece collides with the inner wall of the cylindrical body, the inner wall of the cylindrical body and the beater member vibrate to prevent the object to be treated from adhering to both surfaces, and further, the processed object Is distributed.

In addition, the rolling shaft disposed between the two blade pieces also rolls due to the rotation of the beater member, and the workpiece is pulverized and sized by the rolling shaft.
Japanese Unexamined Patent Publication No. 2000-42437 (paragraph numbers 0015-0020, etc.)

  However, the configuration described in Patent Document 1 causes the following problems.

  In the apparatus described in Patent Document 1, the beater member (a plurality of blade pieces) extends in the longitudinal direction (rotational axis direction) of the cylindrical body, and the rolling shaft also extends in the longitudinal direction of the cylindrical body. For this reason, the rolling shaft can be moved only in a plane orthogonal to the longitudinal direction of the cylindrical body (hereinafter referred to as a longitudinal orthogonal plane).

  In such a configuration, when the rolling shaft moves to the rotating shaft side of the beater member (in other words, the base end side of the blade piece), the workpiece is compressed between the two blade pieces and the rolling shaft. Then, there is a possibility that the object to be processed adheres to the beater member. In particular, when the object to be processed contains a lot of moisture, the adhesion of the object to be processed to the beater member increases.

  Further, since the moving direction of the rolling shaft is limited to the longitudinally orthogonal plane (two-dimensional plane) of the cylindrical body, there is a limit to the processing efficiency of pulverization / sizing of the object to be processed accompanying the movement of the rolling shaft. . In other words, it is impossible to efficiently perform the particle size adjusting process of the object to be processed, and it is difficult to control the particle size distribution (desired particle diameter) of the object to be processed with this apparatus.

  In order to solve the above-described problems, an object of the present invention is to provide a rotary processing apparatus capable of efficiently performing a sizing process on a workpiece.

  The rotary processing apparatus according to the present invention is rotatable, and includes a cylindrical body that discharges an object to be processed supplied from one end side from the other end side, and a plurality of pieces that can come into contact with the inner wall of the cylindrical body at the distal end portion. A blade unit having a blade portion and capable of rotating in the cylinder according to the rotation of the cylinder; and a dispersion medium disposed in the cylinder and movable in a space including the longitudinal direction of the cylinder. The unit is characterized by having a stopper having an opening that prevents the dispersion medium from passing to the other end side and allows the workpiece to pass to the other end side.

  Here, the distance between the outer periphery of the stopper and the inner wall of the cylinder is made smaller than that of the dispersion medium, thereby preventing the dispersion medium from slipping out between the outer periphery of the stopper and the inner wall of the cylinder. can do.

  Further, if the dispersion medium is arranged in a space formed by two blade portions adjacent to each other in the rotation direction of the blade unit and the inner wall of the cylindrical body, the processing object can be efficiently crushed and crushed in this space. Can be done well.

  Furthermore, if stoppers are provided at both ends in the rotation axis direction of the blade unit, and a dispersion medium is disposed between these stoppers, in the space where the blade unit is disposed in the space inside the cylinder, Crushing and the like can be performed efficiently.

  On the other hand, the blade unit can be arranged in at least a partial region in the cylinder. In addition, the blade unit described above and a plurality of blade portions that can be brought into contact with the inner wall of the cylinder body at the tip portion, and other blade units (having stoppers) that can rotate within the cylinder body according to the rotation of the cylinder body. Blade unit) can be arranged in the cylinder. Furthermore, a sphere or a polyhedron can be used as the dispersion medium.

  If a heating means for heating the object to be processed in the cylinder is provided, heat treatment such as drying or baking of the object to be processed can be performed in the cylinder. Further, if gas supply means for supplying gas is provided in the cylinder and water vapor is used as the gas, the object to be processed can be granulated by the water contained in the water vapor. If superheated steam is used as the gas, the object to be treated can be sterilized by the heat of condensation generated when the superheated steam contacts the object to be treated.

  According to the rotary processing apparatus of the present invention, the blade unit is rotated according to the rotation of the cylindrical body, and the dispersion medium is freely moved in the space in the cylindrical body, thereby efficiently pulverizing the workpiece. It can be carried out. In other words, by efficiently using the space in the cylinder as a moving space for the dispersion medium, it is possible to improve the crushing / sizing / dispersing efficiency of the object to be processed, and to easily process the object having a desired particle diameter. Can get to.

  In addition, by providing the blade unit with a stopper having an opening that prevents the dispersion medium from passing and allows the object to be processed to pass therethrough, the dispersion medium and the object to be processed are separated at the stopper, thereby the cylindrical body. Only the object to be processed can be discharged from the other end of the plate.

  Examples of the present invention will be described below.

  A rotary processing apparatus that is Embodiment 1 of the present invention will be described with reference to FIGS. Here, FIG. 1 is a schematic diagram showing the configuration of the rotary processing apparatus. 2 is a cross-sectional view in the longitudinal orthogonal direction of the rotary processing apparatus, and is a cross-sectional view taken along line LL in FIG. FIG. 3 is a front view (A) and a side view (B) of the blade unit arranged in the rotary processing apparatus.

  In the rotary processing apparatus 1 shown in FIG. 1, a supply-side casing 2 is disposed on one end side of the processing unit 3, and a discharge-side casing 4 is disposed on the other end side of the processing unit 3.

  The supply-side casing 2 is provided with a hopper 22 for supplying an object to be processed (for example, wheat flour and starch) into the processing unit 3. The hopper 22 is provided with a supply path 23 extending into the processing unit 3 through the supply-side casing body 25, and a screw-type feeder (not shown) is disposed in the supply path 23. ing.

  When the feeder in the supply path 23 is driven, the object to be processed supplied into the hopper 22 is pushed out toward the processing unit 3, and the object to be processed is supplied to the processing unit 3.

  The supply-side casing 2 is supported on the base 5 via the moving unit 21, and the supply-side casing 2 is moved to one end (covered portion) of the processing unit 3 by moving the moving unit 21 in the direction of arrow X in FIG. It can be moved with respect to the end portion located on the supply side of the processed material. Thereby, the inspection work inside the processing unit 3 can be easily performed.

  A lid unit 26 is provided at the lower part of the supply-side casing 2. By opening the lid unit 26, an object to be processed or the like that erroneously enters the supply-side casing body 25 from the supply-side casing body 25. It can be taken out.

  Further, as will be described later, a gas (for example, an inert gas or water vapor) supplied into the processing unit 3 from the other end side (a discharge side casing 4 side described later) of the processing unit 3 is disposed at the upper part of the supply side casing 2. Etc.) is provided to the outside of the rotary processing apparatus. Here, if a suction mechanism (not shown) for sucking the gas is connected to the gas discharge port 24, the gas can be discharged efficiently.

  On the other hand, a gas supply unit (not shown) is connected to the discharge side casing 4, and the gas supplied from this gas supply unit is discharged into the discharge side casing main body 45 via the gas supply path 43 in the discharge side casing 4. Led to. Here, in the gas supply machine, for example, high-temperature superheated steam gas can be generated from steam by using high-frequency heating or a gas burner.

  The gas guided into the discharge-side casing body 45 passes through the processing unit 3 and moves toward the supply-side casing 2 side. That is, in the rotary processing apparatus 1 of the present embodiment, the object to be processed is supplied from one end side of the processing unit 3 and the gas is supplied from the other end side of the processing unit 3. The workpiece and the gas will react.

  The discharge-side casing 4 is supported by the table 5 via a moving unit 41 that can move in the direction of the arrow X ′ with respect to the table 5. Then, by moving the moving unit 41 in the direction of the arrow X ′, the position (connection position) of the discharge-side casing 4 with respect to the other end portion of the processing unit 3 can be adjusted.

  Further, a viewing window 42 is provided in the discharge-side casing 4, and this viewing window 42 is used for observing the discharge state of the object to be processed from the processing unit 3 and the state in the discharge-side casing body 45. It is done.

  An object to be processed that has passed through the processing unit 3 (an object to be processed after heat treatment or the like) is discharged into the discharge-side casing body 45. A rotary valve 44 is connected to the lower part of the discharge-side casing main body 45, and the object to be processed in the discharge-side casing main body 45 is continuously moved out of the discharge-side casing main body 45 by the rotating operation of the rotary valve 44. It is supposed to be discharged.

  Next, a specific configuration of the processing unit 3 will be described. As will be described below, the processing unit 3 according to the present embodiment performs pulverization, sizing, and dispersion processing of the object to be processed while performing heat treatment on the object to be processed supplied from the hopper 22. is there.

  In the processing unit 3 of the present embodiment, the supply side of the object to be processed is inclined so as to be higher than the discharge side, and the object to be processed supplied from the hopper 22 to one end side of the processing unit 3 (cylinder 31 described later). The object moves to the other end side while being heat-treated according to the rotation of the cylindrical body 31. When the object to be processed reaches the other end side of the cylindrical body 31, it falls into the discharge-side casing main body 45 from the opening 31 b formed at the other end of the cylindrical body 31.

  As described above, in the rotary processing apparatus 1 according to the present embodiment, a predetermined processing (for example, heat treatment, dispersion processing, pulverization / disintegration processing, sizing) is performed on the processing object by putting the processing object into the hopper 22. Treatment, granulation treatment, sterilization treatment) can be carried out continuously.

  Here, if water vapor is supplied from the gas supply device into the processing unit 3 to which the object to be processed is supplied, the object to be processed can be granulated by moisture contained in the water vapor. Further, if superheated steam is supplied into the processing unit 3, the object to be treated can be sterilized by the condensation heat generated when the superheated steam contacts the object to be treated, and the condensate generated at this time Thus, the granulation of the object to be processed can be performed.

  The processing unit 3 includes a cylindrical body 31 in which an object to be processed is stored, and a coil 32 that covers the outer peripheral surface of the cylindrical body 31 and is disposed at a predetermined interval with respect to the outer peripheral surface. Here, the coil 32 is supported by the table 5 via the support member 36.

  In this embodiment, the cylindrical body 31 is induction-heated by passing an electric current through the coil 32 by an electromagnetic induction heating method (high-frequency heating). Here, the interval between the outer peripheral surface of the cylindrical body 31 and the inner peripheral surface of the coil 32 is provided such that the cylindrical body 31 can rotate with respect to the coil 32 in a fixed state.

  The coil 32 is provided with three (or three or more) heating regions A to C, and the heating temperatures in the heating regions A to C are set to be different from each other.

  Here, the entire cylindrical body 31 may be heated by the coil 32 at the same temperature, or a part of the area may not be heated. Further, the number of heating regions can be set as appropriate.

  A heat insulating material for keeping the cylinder 31 warm can be inserted into the space between the outer peripheral surface of the cylinder 31 and the inner peripheral surface of the coil 32.

  Tire flanges 33 are provided at both ends of the cylindrical body 31, and each tire flange 33 is supported by a pair of rollers 34 (see FIG. 2) fixed on the base 5. As shown in FIG. 2, each roller 34 has a rotating portion 34a that contacts the tire flange 33 and a support portion 34b that rotatably supports the rotating portion 34a.

  Of the two tire flanges 33, the tire flange 33 positioned on the supply-side casing 2 side (the processing object supply side) has a drive chain 35 connected to a drive source via a power transmission mechanism (not shown). Is provided. When the drive chain 35 receives the driving force from the drive source and operates, the tire flange 33 rotates and the cylinder 31 rotates.

  A plurality of blade units (a first blade unit 37 and a second blade unit 38) are arranged inside the cylinder 31 along the longitudinal direction of the cylinder 31. In this embodiment, as will be described later, two types of blade units 37 and 38 are used. At both ends of the cylindrical body 31, blade stoppers 31a (one is not shown) are provided to prevent the first blade unit 37 from coming off.

  Here, a common structure of the first and second blade units 37 and 38 will be described using the structure of the first blade unit 37.

  As shown in FIG. 2, the first blade unit 37 has three blade portions 37 a extending in the longitudinal direction of the cylindrical body 31. These blade portions 37 a are arranged at equal intervals (approximately 120 ° intervals) in the circumferential direction of the cylindrical body 31. Note that the number of blade portions 37 a and the interval between two blade portions 37 a adjacent in the circumferential direction of the cylindrical body 31 can be set as appropriate.

  Here, the first blade unit 37 is formed so that the diameter of the circumscribed circle (circle contacting the tip of the blade portion 37 a) is smaller than the inner diameter of the cylindrical body 31. That is, in the state where the first blade unit 37 is disposed in the cylindrical body 31, as shown in FIG. 2, at least one of the three blade sections 37a does not contact the inner wall of the cylindrical body 31. It is like that. In other words, when the cylindrical body 31 is in the non-rotating state, the first blade unit 37 is in a stationary state by the two blade portions 37a coming into contact with the inner wall of the cylindrical body 31.

  When the first blade unit 37 is in a stationary state, when the cylindrical body 31 starts to rotate in one direction (the arrow R1 direction or the arrow R2 direction in FIG. 2), the blade portion that is in contact with the inner wall of the cylindrical body 31 37a moves in this rotation direction according to the rotation of the cylinder 31. When the blade portion 37 a moves by a predetermined amount, the blade portion 37 a that is not in contact with the inner wall of the cylindrical body 31 collides with the inner wall of the cylindrical body 31 due to the weight of the first blade unit 37.

  Thus, when the cylinder 31 rotates, the first blade unit 37 also rotates in the same direction.

  Here, the rotational speed of the first blade unit 37 until the blade portion 37 a collides with the inner wall of the cylindrical body 31 is higher than the rotational speed of the cylindrical body 31. Therefore, the object to be processed accommodated in the cylinder 31 is dispersed throughout the cylinder 31 by the rotation of the first blade unit 37.

  When the object to be processed is small-diameter particles, the object to be processed can be dispersed so as to float in the cylinder 31, and the reactivity between the gas supplied into the cylinder 31 and the object to be processed is obtained. Can be improved.

  In addition, the workpiece having a relatively large weight slides on the surface of the blade portion 37 a by the rotation of the first blade unit 37. And the reactivity of a to-be-processed object and gas can be improved by sliding a to-be-processed object on the surface of the blade part 37a.

  On the other hand, the object to be processed may adhere to the surface of the first blade unit 37 or the inner wall of the cylindrical body 31, but as described above, the blade portion 37 a is moved by the rotational operation of the first blade unit 37. The object to be processed attached to the blade portion 37 a and the cylindrical body 31 can be separated from the blade portion 37 a and the cylindrical body 31 by an impact caused by the collision with the inner wall of the blade portion 37 a. Thereby, it can suppress that a to-be-processed object will remain in the state which adhered to the braid | blade part 37a etc., and can improve the process efficiency (for example, crushing efficiency and sizing efficiency) with respect to a to-be-processed object.

  Next, the configuration of the second blade unit 38 will be described with reference to FIG. The second blade unit 38 has a configuration described below in addition to the configuration of the first blade unit 37 described above.

  As shown in FIG. 3, the second blade unit 38 has a blade portion 38a having the same shape as the blade portion 37a of the first blade unit 37. At both ends in the longitudinal direction, a disk shape is formed. A stopper 38b is provided.

  Further, as shown in FIG. 1, a plurality of dispersion media 39 such as metal or ceramic beads, balls, and polyhedrons are arranged in the region where the second blade unit 38 is arranged.

  Specifically, as shown in FIG. 2, a plurality of blades 38 a adjacent to each other in the circumferential direction of the cylindrical body 31 and a space surrounded by the inner wall of the cylindrical body 31 (hereinafter referred to as a moving space) include a plurality of pieces. A dispersion medium 39 is arranged. As will be described later, the dispersion medium 39 is dispersed in the cylindrical body 31 by the rotation of the second blade unit 38, and pulverizes the workpiece.

  Each dispersion medium 39 is formed of a substantially spherical body or a polyhedron, and can move in the radial direction and the longitudinal direction of the cylindrical body 31 in the above-described movement space. In the present embodiment, the dispersion medium 39 is composed of a sphere or a polyhedron that approximates a sphere, but is not limited thereto. That is, the shape of the dispersion medium 39 may be any shape that can move in the radial direction and the longitudinal direction of the cylindrical body 31. Specifically, a dispersion medium having an elliptical cross section or a dispersion medium composed of a polyhedron approximating this shape can be used.

  Moreover, the number of the dispersion media 39 arrange | positioned in each movement space can be set suitably.

  On the other hand, a gap is formed between the tip of the blade portion 38 a and the inner wall of the cylindrical body 31, and the gap is smaller than the diameter of the dispersion medium 39. In other words, the dispersion medium 39 can move only within the movement space surrounded by the two blade portions 38a and the cylinder 31, and the dispersion medium 39 arranged in the specific movement space can move to another movement space. It is designed not to move in. Thereby, it is possible to prevent the dispersion medium 39 from being shifted into one moving space.

  The outer diameter of the stopper 38b is smaller than the diameter of the circumscribed circle of the blade portion 38a. That is, as shown in FIG. 3A, the tip of the blade portion 38a protrudes from the outer peripheral edge of the stopper 38b.

  The stopper 38b is provided with a plurality of openings 38c extending in one direction (the left-right direction in FIG. 3A). The width W of each opening 38c is smaller than the diameter of the dispersion medium 39 and larger than the diameter of the workpiece. By setting the width W of each opening 38c in this way, the stopper 38b can allow the workpiece to pass and prevent the dispersion medium 39 from passing. In other words, the object to be processed and the dispersion medium 39 can be separated by the stopper 38b.

  Furthermore, although the outer diameter of the stopper 38b is smaller than the inner diameter of the cylinder 31, the gap (largest part gap) D generated between the outer peripheral edge of the stopper 38b and the inner wall of the cylinder 31 is: The diameter is smaller than the diameter of the dispersion medium 39. Thereby, it is possible to prevent the dispersion medium 39 from passing through the gap between the stopper 38b and the cylindrical body 31.

  In this embodiment, the stopper 38b is provided with a plurality of openings 38c extending in one direction, but the present invention is not limited to this. That is, it is sufficient that the dispersion medium 39 and the object to be processed can be separated by the stopper 38b, and the shape of the opening 38c can be appropriately set within a range in which this function can be ensured.

  For example, a plurality of polygonal or substantially circular openings can be formed. Also, these openings can be arranged in a matrix or randomly. Furthermore, a plurality of openings (or notches) extending in the radial direction with respect to the rotation axis of the second blade unit 38 can be formed.

  In the present embodiment, the outer shape of the stopper 38b is formed in a circular shape. However, the outer shape is not limited to this. For example, the stopper 38b may be formed in a polygonal shape. That is, the shape of the stopper 38b may be a shape that fits in the circumscribed circle region of the blade portion 38a, and the gap between the stopper 38b and the cylinder 31 can prevent the passage of the dispersion medium 39.

  Furthermore, in the present embodiment, as shown in FIG. 1, one second blade unit 38 is arranged in the cylindrical body 31, but the number of the second blade units 38 can be set as appropriate. For example, all the blade units arranged in the cylinder 31 can be the second blade unit 38. Further, the position where the second blade unit 38 is arranged in the cylindrical body 31 can be set as appropriate.

  In this embodiment, as shown in FIG. 3B, the stoppers 38b are provided at both ends in the longitudinal direction of the second blade unit 38. However, the position and number of the stoppers 38b can be set as appropriate.

  For example, the stopper 38b may be provided only at one end in the longitudinal direction of the second blade unit 38 (an end located on the supply side of the object to be processed or an end located on the discharge side of the object to be processed) A stopper 38b can be provided at a substantially central position in the longitudinal direction of the blade unit 38 (for example, a position P shown in FIG. 3B).

  Here, when one stopper 38b is used, it is necessary to dispose the dispersion medium 39 closer to the workpiece supply side than the position of the stopper 38b. Further, in the arrangement relationship of the blade units 37 and 38 shown in FIG. 1, when the stopper 38 b is provided only at the end portion of the second blade unit 38 located on the supply side of the workpiece, A dispersion medium 39 is disposed on a first blade unit 37 positioned on the supply side of the workpiece with respect to the blade unit 38.

  Here, when the processing unit 3 is tilted so that the supply side of the workpiece is higher than the discharge side, the workpiece and the dispersion medium 39 move to the discharge side of the workpiece. Therefore, the dispersion medium 39 and the object to be processed can be separated only by providing the stopper 38 b on the object discharge side with respect to the dispersion medium 39.

  In the present embodiment, the case where a plurality of blade units are used has been described, but one blade unit having a length substantially equal to that of the cylindrical body 31 can also be used. In this case, the stopper 38b described above can be provided at a specific position (one place or a plurality of places) in one blade unit.

  Here, by arranging a plurality of blade units in the cylindrical body 31 as in the present embodiment, the blade units can be easily replaced. That is, the blade unit can be easily taken out from the cylindrical body 31 as compared with the case where one large blade unit that covers the entire length of the cylindrical body 31 is used.

  In the rotary processing apparatus 1 of the present embodiment, the blade units 37 and 38 can be taken out from both ends of the cylindrical body 31 by moving the supply side casing 2 and the discharge side casing 4 away from the processing unit 3. . Since the blade units 37 and 38 arranged in the cylinder 31 are not fixed to the cylinder 31, they can be easily taken out from the cylinder 31. When the blade units 37 and 38 are taken out, the blade stoppers 31 a arranged at both ends of the cylinder 31 are removed from the cylinder 31.

  Further, when a plurality of blade units are used as in the present embodiment, only the blade units that have been damaged need to be replaced. That is, when a large blade unit is used, the blade unit itself must be replaced even when a part of the blade unit is damaged, but the blade unit is divided into a plurality of parts as in this embodiment. Thus, only the blade unit that needs to be replaced can be replaced, and the cost associated with replacement of the blade unit can be reduced.

  Moreover, in the area | region where this 2nd blade unit 38 is arrange | positioned by using the 2nd blade unit 38 mentioned above as an at least 1 blade unit among several blade units arrange | positioned in the cylinder 31. FIG. In addition, it is possible to efficiently pulverize the workpiece.

  As described above, in this embodiment, the dispersion medium 39 can freely move in the moving space formed by the two blade portions 38 a adjacent to each other in the circumferential direction of the cylindrical body 31 and the inner wall of the cylindrical body 31. It has become. That is, the dispersion medium 39 can move not only in the radial direction of the cylinder 31 but also in the longitudinal direction of the cylinder 31.

  Specifically, each dispersion medium 39 is moved in the radial direction and the longitudinal direction of the cylinder 31 by the rotation of the second blade unit 38, or the cylinder is caused by a repulsive action accompanying a collision with another dispersion medium 39 or the like. 31 in the radial direction and the longitudinal direction.

  By moving the dispersion medium 39 in this way, it is possible to suppress adhesion of the object to be processed to the second blade unit 38 as compared with the case of the apparatus described in Patent Document 1. That is, since the dispersion medium 39 is moved in a three-dimensional space, the object to be processed is crushed as compared with the case where the rolling shaft is moved in a two-dimensional plane as in the apparatus described in Patent Document 1. Efficiency can be improved. In addition, it is possible to easily obtain an object to be processed having a desired particle diameter simply by changing the diameter or number of the dispersion medium 39, and improve the sizing efficiency.

  On the other hand, in order to ensure free movement of the dispersion medium 39 in the movement space of the second blade unit 38, an uneven part may be formed on the surface of the blade part 38a (contact surface with the dispersion medium 39). it can. Thus, by forming the uneven portion on the surface of the blade portion 38a, the dispersion medium 39 that has collided with the surface of the blade portion 38a can be moved in various directions. Thereby, a to-be-processed object can be crushed efficiently and the sizing efficiency of the to-be-processed object can be improved.

  Here, the uneven | corrugated | grooved part mentioned above can be formed using a curved surface and a flat slope. Moreover, the uneven | corrugated | grooved part mentioned above may be formed in the whole surface of the blade part 38a, and may be formed in a part surface. For example, the concavo-convex portion can be formed in a region of the blade portion 38a where the collision frequency with the dispersion medium 39 is high. If formed in this way, the dispersion medium 39 can be moved more efficiently in various directions, and the pulverization efficiency of the workpiece can be improved.

  Further, when the processing unit 3 (cylinder 31) is used in an inclined state, the dispersion medium 39 tends to be shifted to the downstream side (the discharge side of the object to be processed) in the second blade unit 38. An uneven portion may be formed in this region. Thereby, the deviation of the dispersion medium 39 can be suppressed.

  According to the present embodiment, by setting the form (including shape and size) and number of the dispersion medium 39 and the rotational speed of the cylindrical body 31 according to the purpose, the object to be processed processed by the processing unit 3 is set. On the other hand, it can have a desired particle size distribution.

It is the schematic which shows the structure of the rotary processing apparatus which is Example 1 of this invention. It is sectional drawing of the said rotary processing apparatus. It is the figure (A) which looked at the 2nd blade unit from the one end side, and the figure (B) seen from the side surface side.
