In order to guide the large tea leaves to the outside of the box 1, a tea leaf guiding portion 10 is provided on the separation plate 2, and the opening 3 is not provided at that portion.

In addition to the above embodiment, a plurality of separation plates 2 may be provided. Further, it is preferable to prepare a plurality of separation plates 2 having different sizes of the openings 3 and replace them according to the degree of separation. In the case where the vibration driving means is provided, the degree of separation can be changed by changing the degree of vibration.

An installation example of the present invention will be described with reference to the drawings. Reference numeral 11 denotes a vibrating conveyor, the bottom surface of which is formed by a corrugated plate 12. The bottom surface does not have to be the corrugated plate 12, but in order to select well, the corrugated plate 1
2 is good, and in that case, if it is wavy, a sheet-like object may be stuck on a flat bottom surface, even if it is not formed of a plate. In this example, the vibrating conveyor 11 transfers the tea leaves taken out from the tea dryer 32 to a bucket conveyor 31 for feeding into the next machine (such as a finishing machine or a combination machine).

Reference numeral 20 denotes a cyclone which also serves as a suction means and a blowing means, and collects the air sucked from the suction hood 17 into the cyclone 20 via the suction duct 19. The air in the cyclone 20 separates solids such as tea bar stalks and fibrous muscles, is exhausted from the cyclone exhaust pipe 21 by the fan 24, and is blown (exhausted) to the outside from the blower hood 27 through the blower duct 26. I do. Tea bark, fiber streaks and the like separated in the cyclone 20 are discharged from the lower part of the cyclone 20 via the rotary valve 22. A sorting shutter 30 is provided at the connection between the vibration conveyor 11 and the bucket conveyor 31, the suction hood 17 of the cyclone 20 is installed on the upper surface of the connection, and the blower hood 27 is installed on the lower surface of the connection. The suction hood 17 is provided with a suction amount shutter 18 for adjusting the suction amount, and the blower hood 27 is provided with a blower amount shutter 28 for adjusting the blower amount. In addition, between the blower hood 17 and the sorting shutter 30, a sorted material collecting port 29 for collecting a heavy thing such as a chunk of tea astringent is provided.

The dried tea leaves continuously discharged from the tea dryer 32 fall onto the corrugated plate 12 of the vibrating conveyor 11. The tea leaves are mixed with fibrous muscles, stem bark, tea astringent mass and the like which are separated and generated from the tea leaves during the tea making process. By the crank 14 of the deceleration motor 15 and the leaf spring 13, the tea leaves are transported while being vibrated, and due to the unevenness of the wavy processing plate 12, the fiber muscle having a small specific gravity and a large bulk, the stem bark has a large specific gravity to the surface layer A, The small tea leaves of Casa are divided into the lower layer B. The suction hood 17 sucks and collects the surface layer A (fibrous muscle, stem bark) with the cyclone 20 and
, And falls to the chute 40. In the chute 40, the tea leaves are separated by size by the separating plate 2, and the tea leaves that have passed through the opening 3 are discharged to a small tea discharge port 4, and the tea leaves that do not pass through the opening 3 are discharged to a large tea discharge port 5. Is done.
Then, the tea leaves 41 discharged from the small tea leaf discharge port 4 are stored in the collection bag 33, and the tea leaves discharged from the large tea leaf discharge port 5 are stored in the collection bag 34.

The other lower layer B is not sucked, and receives the wind pressure from the air duct 27 while falling. A heavy hard-to-fly material C such as a chunk of tea astringent is separated from the lower layer B and removed from the sorted material collecting port 29 to the outside. Other tea leaves are transferred to the next step by the bucket conveyor 31. When the suction amount shutter 18 is opened, the amount of air that escapes to the outside increases,
The amount of air coming out of the blower hood 27 is reduced, and the suction force is weakened. If the suction amount shutter 18 is closed, the suction force is strong. Therefore, the suction force is appropriately adjusted according to the degree of selection, the suction capacity of the cyclone, and the like. Also, when the air volume shutter 28 is opened, the air volume is weakened, and when the shutter 28 is closed, the air volume is increased. Therefore, the air volume is appropriately adjusted depending on the degree of selection, the cyclone suction capacity, and the like. Further, the degree of sorting can be changed by opening and closing the sorting shutter 30.

In the above installation example, each of the outlets 4,
5 placed the collection bags 33 and 34 to house the tea leaves,
A transport unit may be provided to transport to a device for performing the next processing. Further, the apparatus of the present invention may be installed not only at the installation position of the present installation example but also at a position where tea leaves need to be separated (instead of a chute put into a tea making apparatus).

[0015]

The tea leaf separation chute of the present invention can be separated with a simple structure. Further, the size of the apertures can be changed, and the vibration driving means can be adjusted (presence / absence, strength) to easily separate the tea leaves into a desired state. Since it can be installed in a small space, it can be installed in a current tea factory. The auxiliary role of other sorting devices can also be fulfilled sufficiently.
