Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to selection of tree stems, tea powder, fluff, etc. in a tea processing process.

[0002]

[Prior art]

 An electric sorter is generally used to separate tree stems that are mixed in crude tea (unrefinished tea before marketing). However, the tree stems separated by the electric sorter are other than the stems (the tree stems are roughly divided into red stems with advanced lignification and green stems in the sprout part, but here the green stems are the target). , Genuine tea (the main tea when rough tea is finished), fluff (the skin of the green stem is peeled off), bud tea (the tip part), powder, etc. are mixed, so it is necessary to separate them. There is. Usually, the re-sorting of the main stems separated by the electric sorting machine is carried out through the steps of sieving, cutting and wind power sorting.

[0003]

[Problems to be solved by the device]

 The stem mixed with the crude tea is generated by removing the leaves from the stem while the shoots picked into 3 to 5 leaves are dried by heat and pressure. In many cases, fluff is formed by peeling off a part of the epidermis and forms a bundle. Therefore, in the prior art, a wire mesh cutting machine is used to remove the fluff attached to the stem, but this method makes it impossible to continuously feed the cutting machine. Worse). Insufficient peeling rate. Stem tea (tea with a lot of stems separated by a sorter) is cut and becomes too small. There was a problem that the stem tea was whitened and the quality was deteriorated. The present invention has been made in view of the above problems, and an object of the present invention is to reduce the equipment cost by reducing the number of models for one step, and to provide a high quality and labor-saving stem tea sorting machine. It is the one to be provided.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the stem tea sorting machine according to the present invention has a rotary drum with one end serving as an inlet for wood stems and the other end serving as an outlet, and a large number of them are provided at the center of the rotary drum. In a cylinder rotary stirring type sorting machine in which a stirring shaft provided with stirring blades is suspended, a part or the whole of the rotating cylinder is a wire mesh or a perforated member. The rotational speeds of the rotary drum and the stirring shaft can be changed individually, and the peripheral speed difference between the rotary drum and the stirring blade can be freely changed. Also, the inclination of the rotating drum can be changed.

[0005]

[Action]

 The tree stems put into the rotary drum are sequentially transferred to the discharge port by the rotation of the rotary drum and the stirring shaft. At the inlet side of the rotary drum, bud tea and powder were separated by a wire mesh, and the remaining tree stems were then rubbed on the stem by the rubbing action due to the difference in peripheral speed between the wire mesh of the rotary drum and the stirring blade. The skin of the stem is peeled off and falls mainly from the mesh of the wire mesh of the rotating drum, and part of it is discharged from the discharge port.

[0006]

【Example】

 Examples will be described with reference to the drawings. 1 and 2, reference numeral 1 denotes a rotating cylinder, one end of which is loosely fitted with an inlet 2 and the other end of which is an outlet 3. The rotating cylinder 1 is a transmission device for a ring gear 12 (not shown). The rotation speed is freely controlled via. One-fifth of the inlet 2 side of the rotating cylinder 1 is a mesh with a 10-mesh wire mesh 5, and four-fifth of the outlet 3 side is an 8-mesh wire mesh 4. Reference numeral 6 denotes a stirring shaft provided with a large number of stirring blades 7, which extends through the center of the rotating cylinder 1 and is driven by a driving unit 10 at a freely rotating speed. In addition, with respect to the wire netting 4 portion of the stirring blade 7, a rubber plate 9 is provided at the tip of the flat rope 8 and the wire netting 4 of the rotary cylinder 1 is provided so as to be in contact with the wire netting 4 with a margin. Therefore, the tree stalks continuously charged from the charging port 2 separate powder and bud tea in the 10 mesh portion of the wire net 5 of the rotating cylinder 1, and the peripheral speed difference between the rotating cylinder 1 and the stirring blade 7 causes The remaining tree stems are discharged to the discharge port 3 while giving a rubbing action to the tree stems. A blind plate 14 is provided at the boundary between the wire net 5 and the wire net 4 of the rotary cylinder 1, and the blind plate is slid to adjust the separation ratio of bud tea and powder. Immediately after being charged, the bud tea and powder fall from the sieve mesh of the wire mesh 5 and are separated into the discharge port 16. Further, the epidermis of the stem attached to the stem as fluff is sufficiently peeled off to separate into stalk and fluff, and mainly the stalk falls from the wire net 4, and most of the fluff is discharged from the discharge port 3. Further, the tree stems separated from the wire net 4 are conveyed to the discharge port 17 by the screw conveyor 15 and mixed with those discharged from the discharge port 3. Reference numeral 10 is a drive unit that is individually transmitted to the rotary cylinder 1 and the stirring shaft 6, and the drive unit is freely changed within the range of the rotation cylinder 1: the rotation speed ratio of the stirring shaft 6 of 1: 5 to 1:15. It is a mechanism that can be done. Further, the rotating cylinder 1 can be changed in inclination angle by the handle 11 from the horizontal position to 5 degrees downward. Reference numeral 13 is a brush for removing clogging of the wire net 5 and enhancing the sieving effect, and is attached in contact with the mesh openings of the wire net 5 of the rotary cylinder 1.

[0007]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. In the conventional stem tea selection method, three steps are performed, but in the present invention, one step can be deleted, so that the equipment cost can be reduced. In addition, a high separation effect of stems and fluffs can be expected regardless of the input amount, so that the stem and fluffs can be selected by the next step of wind power selection, and a high quality stalk tea can be obtained. Furthermore, since continuous operation is possible, the labor saving effect is also great.
