A large number of large-diameter rotary sizing tubes (2a) in which numerous fine sizing holes (1a) are formed are slightly larger than a large-diameter rotary sizing tube (2a). A rotary granule (2) having a small diameter, which is made long, is inserted and integrally formed, and is horizontally laid with its rotation axis being gently inclined, and the lower inlet is positioned from the upper inlet (3). The small particles are leaked from the peripheral surface of each of the rotary granules (2) and (2a) while the small particles are flowing toward the wadding (4), and the small particles are rotated. A receiving gutter (8) that receives the leakage of the large-diameter rotary sizing cylinder (2a) from the sizing cylinder (2), and a large-diameter rotary sizing cylinder that leaks from the small-diameter rotary sizing cylinder (2) ( A receiving gutter (9) for receiving the one that does not leak 2a), a receiving gutter (10) for receiving the one that does not leak the small-diameter rotary granule (2), and the like.

In addition, two small-diameter rotary sizing cylinders (2) are inserted into the large-diameter rotary sizing cylinders (2a) to be integrally formed and horizontally mounted in a gentle inclination state. It is a fryer (7)
The particles lifted by the inlet are distributed and juxtaposed at the inlet of each of the small-diameter rotary sizing cylinders (2), which flow into the wadding (3) to be sieved. A medium-grained one falls on the gutter (9), and a large grain falls on the gutter (10), and the automatic weighing tool (11) attached to the outlet of each gutter (8) (9) (10) respectively. It is measured in a fixed amount.

The small-diameter rotary sizing cylinder (2) is inserted into the large-diameter rotary sizing cylinder (2a) to be integrated, and two of them are arranged side by side on the frame (12). The rotary power of the electric motor (M) is supplied from the inlet (3) inside the structure (13), and the outlet (4) is supported by the support (14) suspended from the structure (13). ) Is rotatably supported by a support cylinder (15) projecting toward the waist (3) on the axis of the rotation shaft.

The entrance (3) of the structure (13) is supported at its lower part by a support (16) projecting upward from above the frame (12), and the frame (12) has an opposite shape. A control motor (17) is mounted on the upper part, and a shaft (18) of the control motor (17) is screwed into a receiving metal (19) attached to the structure (13). The structure (13) is moved up and down with the axis (20) as a fulcrum by the forward or reverse rotation of the rotary table (17) to change the inclination angle of the small- and large-diameter rotary selection cylinders (2) and (2a).

Further, a flow rate sensor (S) for detecting a flow rate of a flow flowing from the inlet (3) to the outlet (4) in the small-diameter rotary granule (2) is provided. The sensor (S) detects the flow rate in the case where the outlet in the cylinder is near the wobble (4) and most of the small and medium particles have leaked and the large particles have leaked. The flow rate sensor (S) is connected to the control motor (17) via a control circuit by a wire passing through the inside of the support cylinder (15), and is rotated by the amount detected by the flow rate sensor (S). Granule (2)
And the inclination angles of (2a) are both changed and adjusted.

That is, when the amount of detection is large, the inclination angle is adjusted to be small to increase the flow time from the inlet (3) to the outlet (4) in the cylinder, and when the amount is small, the inclination angle is reduced. It becomes larger and shortens the flow time in the cylinder.

Next, a diffusing member (5) as shown in FIGS. 3 to 5 is provided in the small-diameter rotary sizing cylinder (2). The diffusion member (5) is a relatively narrow plate having a narrow width, and several members are provided along the inner peripheral surface of the rotary granulation cylinder (2) at intervals in the direction of the rotation axis.

The base end is slightly bent obliquely upward to form a non-slip surface (5b) connected to the working surface (5a).

Therefore, the rotary granule (2) rotates in the direction of the arrow (a), soybean flows from the inlet (3) to the outlet (4), and the soybean flows from the granulation hole (1). If the flow rate in the rotary sizing cylinder (2) is small when the sizing is performed by leakage, the soybean is agitated with the working surface (5a) while rotating while maintaining the state shown by the solid line in FIG. The non-slip surface (5b) prevents the outlet from sliding out of the working surface (4) from the operating surface (5a) while giving an effect, and when the flow rate becomes large, the load received from the flowing soybean becomes large and the virtual surface becomes imaginary. As shown in the line (b), the posture is changed to an oblique state in which the free end rotates behind the base end and rotates so that the soybean returns to the inlet (3) and returns to the soybean in addition to the stirring effect. It is.

In this embodiment, the diffusion member (5) is described as being made of an elastic material. However, an inelastic material may be used. In that case, the diffusion member (5) is used.
The base mounting portion (5c) is connected to the inner peripheral surface of the rotary granulation cylinder (2) by the set bolt (21), and the free end is urged by a spring or the like, and is shown by a solid line in FIG. To be kept.

Although the diffusion members (5) are arranged at intervals in the direction of the axis of rotation in the example, the invention is not limited to such a configuration. What is necessary is just to arrange | position suitably on an inner peripheral surface like a staggered shape.

The present invention is embodied in the form described above, and has the following effects.

That is, a rotary granulation cylinder having an infinite number of granulation holes formed on its peripheral surface is laid horizontally with its rotation axis being in a gently inclined state. A granulator for soybeans, in which the granules are leaked from the granulation hole while the outlet is continuously fluidized toward the side, and granulated by the size of the granules, wherein the rotary granulation cylinder is Since the inclination angle is variable and a flow rate sensor for detecting the flow rate in the rotary granule is provided and the inclination angle can be changed and adjusted by the detection amount of the flow rate sensor, when the flow rate is large, Decreases the inclination angle of the rotary granulation cylinder, lengthens the flow time in the cylinder,
When the amount is small, the inclination angle becomes large, the flow time is shortened, and the leakage from the sizing holes is improved in response to the fluctuation of the flow rate, whereby the sizing accuracy and the sizing efficiency can be improved.

By providing the flow rate sensor near the outlet in the rotary sizing cylinder, most of the small sized particles leak out of the sizing holes and then the large sized ones are targeted. Since the flow rate is detected, the angle of inclination of the rotary sizing cylinder is adjusted to an appropriate sloping state without being affected by the material conditions, such as when the ratio of small particles to the total amount of sizing material is large. Become.

Further, a rotary granulation cylinder having an infinite number of granulation holes formed on the peripheral surface thereof is laid horizontally with its rotation axis being in a gently inclined state. Rotating several diffusion members in a soybean granulator, in which small granules leak out from the granulation holes while continuously flowing toward the side and are granulated according to the size of the granules. Provided in the direction of the axis of rotation of the cylinder along the inner peripheral surface of the grain cylinder, the diffusion member is attached to the inner peripheral surface at the base end of the outlet waist and the inlet waist is a free end. By adopting a configuration in which the free end rotates backward from the base end in a slanted state against the urging force, the diffusion member stirs the soybeans to promote leakage from the sizing holes while rotating soybeans. The posture of the slanted state changes according to the load fluctuation of the soybean due to the difference in flow rate in the sizing cylinder, and the soybean is turned back to the inlet and returned into the cylinder. It takes to adjust the flow time to improve the selection particle accuracy and efficiency by.

The diffusion member is formed by folding up its base end to form a non-slip surface connected to the working surface.
When the flow rate in the rotary sizing cylinder is small, soybeans that slide out of the outlet from the working surface of the diffusion member are prevented by the non-slip surface, and the sizing operation is repeatedly performed to further improve the sizing accuracy. Can be.

The diffusion member is made of an elastic material so that the free end is inclined so that the free end rotates backward from the base end by the load of the flowing soybean, so that the diffusion member has a simple structure. In addition, it is possible to effectively perform the agitation and the return operation to the inlet in response to the load fluctuation of the flowing soybean.
