[0027]
Here, the scraping device according to the present embodiment is disposed in the vicinity of the lower portion of the charging valve 9 in the dryer main body 2, and as shown in FIG. It is mainly composed of a means 25, a sieve means 26 provided in the middle of the conveying means 25, a vibration conveyor 27 as a storage means, and a suction means 28.
[0028]
The conveying means 25 is attached to a frame 33 fixed on the floor surface via a pedestal 32 supported by leaf springs 34 and 35, and one end side (charge) while vibration is applied by a driving source (not shown). The tea leaves are transported from the second valve 9 side) to the other end side (left side in the figure). The conveying means 25 is mainly composed of a first collar part 29, a second collar part 30, and a sieving means 26.
[0029]
The first flange portion 29 is a stainless steel member that constitutes one end side of the conveying means 25 and is provided with a rear surface and a side flange, and is attached to the pedestal 32 so as to be inclined forward by a predetermined angle with respect to the floor surface. ing. On the front side where the flange is not erected, a sieving means 26 fixed by a mounting washer 31 is formed.
[0030]
The sieving means 26 is made of a stainless steel plate for dropping and sorting the tea leaves conveyed by the first ridge part 29. As shown in FIG. 3, the sieving means 26 extends from one end side to the other end side of the conveying means 25. It has a plurality of long holes 26a extending (in the vertical direction in the figure). The long hole 26a is opened at the other end side of the conveying means 25 and has a comb shape, but may be a long hole that does not open.
[0031]
The long hole 26a is preferably formed with an appropriate size so as to leave only the fluffy fluff while passing the wire-like hard tea or tea powder downward. In the embodiment, for example, the width h is 60 mm. In this plate material, a plurality of long holes 26a having lengths L1 and L2 of about 45 mm and 36 mm and having an appropriate clearance w are formed. Reference numeral 26 c in the figure denotes a screw hole for connecting the sieving means 26 to the mounting washer 31 and the first flange 29.
[0032]
The second flange 30 is a stainless steel member that extends from directly below the opening of the long hole 26a to the other end of the conveying means 25, and has an upper surface that forms a conveying surface for scrapes and a side flange that is erected. That is, the tip of the sieving means 26 and the rear end of the second flange 30 are overlapped with different heights, so that the fluff that has fallen from the opening of the long hole 26 a reaches the second flange 30. It is configured.
[0033]
The vibration conveyor 27 is disposed below the sieving means 26, and accommodates tea dropped from the sieving means and conveys the tea to the next process. As shown in FIG. 4, the vibrating conveyor 27 is supported by leaf springs 36 and 37 so that the conveying surface is vibrated by a driving source 38.
[0034]
The suction means 28 is for sucking the leaves of the tea that has passed over the sieving means 26 and has been transported to the second heel part 30 that constitutes the other end side of the transport means 25, and the second heel part 30. And a cyclone 42 connected to the suction hood 39 via the collective duct 40, and a blower 41 for generating a suction force from the suction hood 39 to the cyclone 42. In FIG. 1, reference numeral 44 indicates a pipe connecting the suction hood 39 and the collective duct 40, and reference numeral 45 indicates a pipe connecting the collective duct 40 and the cyclone 42.
[0035]
A rotary valve 46 is disposed on the discharge port 42a side below the cyclone 42, and is configured to maintain the negative pressure in the cyclone 42 by the blower 41. In other words, the air in the cyclone 42 is blown out by the blower 41 to obtain a negative pressure, and the suction force from the suction hood 39 is obtained by the negative pressure.
[0036]
As shown in FIG. 5, a powder separator 43 is connected to the discharge port 42 a of the cyclone 42 to separate the tea powder sucked from the suction hood 39 together with the kerf. The powder separator 43 is capable of receiving the sucked invasion and conveys the receiving container 43a having a plurality of small holes 43b formed therein and the incision in the receiving container 43a to a predetermined portion (the right end of the receiving container 43a). It has a feed blade 43c as a kava conveying means.
[0037]
The feed blade 43c is composed of a spiral screw that is rotationally driven by a motor M, and among the crumbs containing tea powder discharged from the cyclone 42, only the crumb is received and conveyed to the right end of the container 43a, and the tea powder is fed from the small hole 43b. They fall and are separated so that the tea powder can be mixed into the product tea. According to such a powder separator 43, the tea powder sucked from the suction hood 39 can be separated from the scraps and returned to the product tea.
[0038]
Instead of the suction means 28, a blower 41 may be connected to the piping 45 and a cyclone 42 may be connected to the air discharge port of the blower 41 as shown in FIG. According to such a configuration, it is not necessary to maintain a negative pressure in the cyclone 42, and the rotary valve on the discharge port 42a side can be made unnecessary. In addition, you may make it connect the above-mentioned powder separator 43 to the discharge port 42a of the cyclone 42 applied to this form.
[0039]
Next, the operation of the debris removing device having the above configuration will be described.
The tea leaves that have been dried by the dryer 1 are discharged from the charging valve 9 and dropped onto the first brim 29 in the transport means 25, and reach the sieve means 26 while receiving vibration. Here, as shown in FIG. 7, the fluffy bent bow A does not fall at the long holes 26a, but is caught by the protrusions 26b between the adjacent long holes 26a, and moves in the direction of the arrow as it is. Then, while being dropped and conveyed from the opening of the long hole 26a to the second eaves part 30, the needle-shaped hard tea B or tea powder C is dropped from the long hole 26a to the vibration conveyor 27, and the vibration conveyor 27, it is transported to the next process and made into a tea product through a bagging process and the like.
[0040]
In the sorting by the sieving means 26, one needle-like hard tea B falls from the long hole 26a, but, for example, a plurality of teas are overlapped so as not to fall from the long hole 26a, or approximated as a kava. The shaped tea or the like passes over the sieving means 26 and falls to the second heel part 30 in a state of being mixed with the cracks. In other words, since the purpose of the sieving means 26 is to perform rough sorting, it is anticipated that tea leaves other than kef will be mixed to some extent. Rather, more strict knot sorting is possible by suction by the suction means 28 described below. Will be done.
[0041]
That is, a thing that passes over the sieving means 26 and reaches the second collar part 30 is given a suction force of a predetermined pressure in the suction hood 39, so that the fluffy and light injuries are sucked while being hard. The relatively heavy tea is not sucked and falls to the vibrating conveyor 27 from the other end of the second collar 30. In order to perform such a suction action, it is necessary to set the suction force generated by the blower 41 to a predetermined value in advance so as to suck light leaves while not sucking relatively heavy brown.
[0042]
Although the inhalation is sucked into the suction hood 39 by the suction force, a very small amount of tea powder is sucked in this case. The leaves containing the tea powder sucked in this way are sent into the cyclone 42 through the suction hood 39, the pipe 44, the collecting duct 40 and the pipe 45, and dropped into the powder separator 43. The powder separator 43 separates the tea powder sucked by the suction hood 39, removes only the scraps, and the series of scraping work is completed.
[0043]
According to the present embodiment, the long hole 26a formed in the sieving means 26 separates the kerva and other teas, so that clogging is suppressed compared to a conventional sieve having a substantially square mesh. can do. In other words, because the fluff is usually fluffy and bent, if it gets caught in the mesh, it will stay on the sieve and cause clogging even if vibration is applied thereafter, whereas in the long hole 26a, it is sieved. Since it is configured such that the hook caught above flows smoothly in the conveying direction by vibration and falls from the opening of the long hole 26a, clogging can be suppressed. In addition, since this anti-blemishing device is provided on the discharge port side of the dryer installed in the final step of the tea production process, there is no room for flaking in the subsequent steps, and it is ensured that the product tea will be mixed in. Can be prevented.
[0044]
Next, another embodiment of the present invention will be described.
As shown in FIGS. 9 and 10, the scraping device according to the present embodiment has one end 25 a immediately below the charge valve 9, and conveying means 25 disposed in the vibration conveyor 27 as shown in the figure, It is mainly composed of sieving means 26x, 26y and 26z provided in the middle of the conveying means 25, a vibration conveyor 27 as an accommodating means, and a suction means including a suction hood 39.
[0045]
The conveying means 25 has a first component part composed of a conveying plate 25c and a sieving means 26x fixed to the tip thereof, and a predetermined dimension below the first component part, and is predetermined with respect to the tip of the sieving means 26x. A second component part composed of sieve means 26y arranged with overlapping dimensions and a predetermined dimension lower than the second component part and arranged to overlap the tip of sieve means 26y by a predetermined dimension And a third component part composed of the sieving means 26z. Each component part is fixed to the inner peripheral wall of the accommodating portion in the vibration conveyor 27.
[0046]
In this way, by configuring the sieving means in three stages, it is possible to increase the size of the sieving means in the longitudinal direction as compared with the previous embodiment, and it is possible to maintain the sorting processing capability by the sieving means. That is, compared with the conveying means 25 according to the previous embodiment that can be relatively wide, the conveying means arranged in the vibration conveyor is relatively narrow, and only by one sieving means. In the sorting of tea leaves, the sorting process cannot catch up, and the sorting becomes extremely rough. Therefore, the size in the longitudinal direction occupied by the sieving means is set longer to improve the sorting processing capability.
[0047]
In the present embodiment, the conveying means 25 is composed of three stages, but may be two stages as long as the improvement of the sorting processing capability is achieved, and more preferably four stages or more. In the present embodiment, the sieving means 26x is fixedly provided at the front end of the transport plate 25c, but a long hole is formed at the front end of the transport plate, and the transport plate 25c and the sieving means 26x are configured integrally. It is good.
[0048]
As shown in FIG. 11, the sieving means 26 (common to all of 26x, 26y and 26z) has a plurality of elongated holes 26a extending from one end 25a side to the other end 25b side of the conveying means 25 and having open ends. The two are stacked. That is, long holes 26d extending left and right are respectively formed on the base end sides of the sieving means 26 and 26 ', and the bolt B is passed through the long hole 26d in a state where the sieving means 26 and 26' are overlapped. At the same time, a nut (not shown) is screwed and tightened from the tip of the bolt B, whereby the two sieving means 26 and 26 'are integrated.
[0049]
According to the sieving means having a structure in which two sheets are stacked in this way, if the nuts are loosened and the sieving means 26 and 26 'are relatively shifted in the left-right direction, and then the nuts are tightened again, as shown in FIG. Furthermore, since the clearance w of the long hole 26a can be set to wa, the following effects can be obtained. That is, the proportion of tea powder and keba contained in tea varies greatly depending on the tea leaf picking time and the degree of steaming in the tea steaming process, and the selection effect may be insufficient with a certain clearance w. According to the embodiment, since the clearance can be adjusted according to the tea to be screened, the sorting operation can be made more accurate.
[0050]
The vibration conveyor 27 and the suction means (only the suction hood 39 is shown) have the same configuration as that of the previous embodiment, and a detailed description thereof will be omitted. However, as shown in FIG. It is preferable to be disposed so as to cover 26y and 26z. Further, according to the present embodiment, since tea is transported by a relatively narrow transport means, it is not necessary to make the opening of the suction hood 39 so large, and suction force generated by a blower (not shown) is generated. Compared to the previous embodiment, it has the advantageous effect of being small.
[0051]
Although the present embodiment has been described above, the present invention is not limited to this. For example, instead of the vibration conveyor 27, other accommodating means (for example, other conveying means such as a belt conveyor, a container having a certain capacity, etc.) ) May be provided, and other general suction means may be used instead of the suction means of the present embodiment. Further, the conveying means 25 may be configured to revolve like a rotating sieve in addition to those that vibrate, and may be configured to convey tea leaves from one end side to the other end side by such a swiveling action. Furthermore, in addition to vibration and turning motion, other operations may be performed as long as the tea leaves are transported from one end side to the other end side of the transport means 25. Furthermore, although this scraping device is disposed on the discharge port side of the dryer, the present invention is not limited to this and can be disposed at various positions in the tea making process.
[0052]
