Description

Technical Field

[0001] The present invention relates to a loose tea device that cools and puts tea leaves into a matcha furnace or the like in an opened state.

Background Art

[0002] Matcha is obtained by steaming the coated tea leaves and then drying them without kneading, and it is the raw material for matcha. Its shape is thin like leaves spreading out and transparent, the color is bright green, and the fragrance has a unique furnace aroma. This matcha is manufactured by performing each process of steam heating, loose tea cooling, drying, separation, and finishing drying. Drying is carried out in a matcha furnace that dries the tea leaves conveyed by a conveying means such as a conveyor by radiant heat transfer and natural convection heat transfer, or a matcha furnace that dries by forcing hot air to flow through (continuous convection heat transfer dryer), etc. In front of this matcha furnace, a loose tea device for putting tea leaves into the matcha furnace is arranged (see, for example, Patent Document 1 and Patent Document 2, etc.).

[0003] The loose tea device is for the purpose of cooling, leaf opening (loosening and spreading the adhesion or breakage between tea leaves due to the surface moisture of the tea leaves), and input. Specifically, it includes a cage composed of a rectangular tube-shaped side portion having air permeability, for example, made of a wire mesh, and a ceiling portion arranged at the upper end of the side portion. While putting tea leaves into this cage, it is blown upward by a blowing means such as a blower, and the tea leaves that have fallen naturally are put into a conveyor or the like of the matcha device. In front of the loose tea device, it is common to provide one to several so-called "lanterns", which are bag-shaped nets suspended from a tower-shaped frame about several meters high. While putting tea leaves into these lanterns in order and blowing them upward by a blowing means such as a blower, the tea leaves that have passed through the last lantern are put into the matcha furnace from the loose tea device.

[0004] Here, when the tea leaves are put into the matcha roasting furnace in a state where they are attached to each other from the loose tea leaf device, the surface moisture of the tea leaves existing between the attached tea leaves and the tea leaves does not completely dry in the initial stage of drying, resulting in a drying difference (drying unevenness) with the tea leaves that have undergone other drying processes. Also, when putting in the tea leaves one by one, if they are put on top of the previously put-in tea leaves, drying unevenness will occur as described above. In either case, if the tea leaves proceed to the drying process while overlapping, the drying unevenness will cause discoloration on the surface of the tea leaves. The overlapping part will turn black, and the product will become dull in color, which is a drawback for the bright green matcha. If there are many overlapping parts, it will be difficult for the tea leaves to dry, and in order to dry the overlapping parts, the temperature in the drying chamber of the matcha roasting furnace will be increased for drying. In that case, the parts where drying is proceeding without overlapping will become over-dried, and this over-drying will also cause discoloration or loss of aroma.

[0005] For this reason, it is ideal to put the tea leaves into the matcha roasting furnace one by one over the entire width, that is, over the entire width of the conveyor or the like in the matcha roasting furnace. Like the loose tea leaf device described in Patent Document 1, various proposals have been made to achieve this. Specifically, in the loose tea leaf device described in Patent Document 1, a blowing means capable of adjusting the blowing distribution in the width direction of the conveyor or the like is adopted, and an attempt is made to make the blowing-up distribution of the tea leaves substantially uniform and to make the tea layer uniform with respect to the conveyor or the like.

[0006] Also, when air passes through the side surface portion composed of a wire mesh or the like of the loose tea leaf device, it is easy for the eyes to be clogged with so-called tea dust, etc., and if cleaning is not performed frequently, the air permeability of the wire mesh or the like will be impaired, and there is a risk that problems will occur in the blowing-up of the tea leaves. For this reason, proposals have also been made from other viewpoints such as improving cleanability, like the loose tea leaf devices described in Patent Document 2 and Patent Document 3.

[0007] Specifically, the loose tea leaf device described in Patent Document 2 forms a cage by an inner cylinder and an outer cylinder arranged outside this inner cylinder, and forms the boundary surface between the inner cylinder and the outer cylinder with a ventilation net having coarser mesh than other surfaces. And by making the inner cylinder and the outer cylinder detachable, it is configured so that these boundary surfaces can be easily exposed. Thereby, it aims to improve the maintainability such as the removal and cleaning of the tea leaves caught on the boundary surface.

[0008] In addition, the loose tea device described in Patent Document 3 has a net on the side of the cage made of a material having elasticity so that it can be bent and shaken off. By shaking or hitting the net, the tea leaves sticking to the side are dropped, and an attempt is made to omit the work of removing the steamed leaves or the like sticking to the side.

Summary of the Invention

Problems to be Solved by the Invention

[0010] However, as in the loose tea device described in Patent Document 2, the operation of removing the outer cylinder from the inner cylinder, placing it in an appropriate place for cleaning, etc., and then attaching the outer cylinder to the inner cylinder again is very complicated because the cage is as large as about 5 to 7 m in height. Also, even when cleaning is performed with the inner cylinder and the outer cylinder suspended from the frame or ceiling, etc., since it is installed at a high place, it may sometimes be a dangerous operation. In particular, in a general cage that cannot be removed, etc., it is not easy to clean the inside of the cage. Further, in the loose tea device described in Patent Document 3, although the tea leaves sticking to the wire mesh or the like constituting the side can be removed to some extent, it is difficult to remove clogging such as tea dust. For this reason, in order to ensure the air permeability of the wire mesh or the like, cleaning inside the cage, which is complicated and sometimes dangerous, is still necessary.

[0011] From the above, an object of the present invention is to provide a loose tea device in which a device has been devised to easily clean the inside of the cage by paying attention to clogging of the wire mesh or the like constituting the cage.

Means for Solving the Problem

[0012] A first means of the present invention is a loose tea device used in a matcha tea furnace or the like, comprising a cage that defines a blowing space for blowing up tea leaves blown and fed in by a blowing means, wherein the cage has a rectangular tube-shaped side portion having air permeability and a ceiling portion disposed at an upper end of the side portion, wherein the side portion is provided with a net unit on at least one surface, The net unit each has an endless configuration and a pair of endless members respectively disposed on both sides in the width direction, a net body having a predetermined mesh stretched across the pair of endless members in the width direction, and a traveling mechanism for circulating and running the pair of endless members, wherein the net body is capable of circulating and moving between a position facing the blowing space and a position exposed outside the cage as the pair of endless members circulate and run. The loose tea device is characterized by this.

[0013] The matcha tea furnace or the like mentioned here includes a matcha tea furnace dried by radiant heat and natural convection heat, and a matcha tea furnace (so-called net dryer) dried by forced ventilation of hot air. Further, the side portion may be composed of a wire mesh with a predetermined mesh for portions other than the net unit. Furthermore, the net body may be a net of synthetic resin fibers or natural material fibers. Also, the net unit may be provided over the entire at least one surface of the side portion, or may be provided, for example, only in the upper portion of one surface. Further, the ceiling portion may be composed of a wire mesh having air permeability or the like, or may be composed of a metal plate having no air permeability or the like.

[0014] The net body of the first means of the present invention is capable of circulating and moving between a position facing the blowing space and a position exposed outside the cage. Therefore, when clogging such as tea dust occurs at the position where the net body faces the blowing space, for example, while moving the net body to a position exposed outside the cage, cleaning to eliminate clogging can be easily performed using an air blower gun or the like. Furthermore, cleaning can be safely performed while, for example, riding on the upper part of a matcha furnace where a handrail or the like is arranged. In addition, in addition to eliminating clogging of the net body, it is also possible to remove tea leaves or the like adhering to the net body.

[0015] The second means of the present invention is, in the first means, the net unit having a plurality of the net bodies with different mesh openings arranged in the circulating movement direction.

[0016] Here, the net unit may have two types of the net bodies with different mesh openings, or may have three or more types of the net bodies with different mesh openings. Also, so-called gradually, the net bodies with different mesh openings may be used gradually in the circulating movement direction.

[0017] According to the second means of the present invention, by changing the mesh opening of the net body at the position facing the blowing space, it is possible to adjust how much fine powder is mixed into the tea leaves that fall through the blowing space and cannot pass through the net body and are put into the matcha furnace or the like.

[0018] The third means of the present invention is, in the second means, the net unit having a first net body and a second net body with a larger mesh opening than the first net body, The first net body and the second net body are arranged at intervals in the circulating movement direction.

[0019] Here, on one side surface of the side surface part, the mesh unit may be provided, and on the remaining three side surfaces, wire meshes with the same mesh size may be provided. And the first mesh body may be set to have the same mesh size as the wire mesh, and the second mesh body may be set to have a larger mesh size than the wire mesh.

[0020] The fourth means of the present invention is, in the first to third means, that the mesh unit is detachably provided outside the orbit in which the mesh body circulates and moves, and has a blocking member that blocks ventilation from the mesh body, and a collecting means for collecting fine powder that has passed through the mesh body at a position facing the blowing space above.

[0021] Here, the cleaning of the mesh body can be easily performed by moving the mesh body to a position where it is exposed outside the cage while removing the blocking member.

[0022] The fifth means of the present invention is, in the first means or the second means, that the blowing means blows obliquely upward toward the blowing space above to introduce tea leaves, and the mesh unit is provided on a surface facing the direction in which the blowing means blows.

[0023] According to the fifth means of the present invention, the tea leaves blown into the blowing space above collide, and the mesh unit can be provided at a location where clogging such as tea dust is likely to occur.

[0024] The sixth means of the present invention is, in the first means or the second means, that the mesh unit is provided on the path in which the mesh body circulates and moves, and has a removing member for removing tea dust and the like that has clogged the eyes of the mesh body.

[0025] According to the sixth means of the present invention, if the mesh body is circulated and moved manually or by a driving means such as a motor, the tea dust and the like that have clogged the eyes of the mesh body are removed by the removing member composed of an air blower device, a brush, or the like, and the clogging of the eyes of the mesh body and the like can be eliminated. Also, at the same time, tea leaves and the like attached to the mesh body can be removed.

Advantages of the Invention

[0026] According to the present invention, it is possible to provide a loose tea device with a device that enables easy cleaning inside the cage.

Embodiments for Carrying Out the Invention

[0028] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of an embodiment in which the loose tea device 10 of the present invention is arranged in front of the tea rolling furnace 9, and FIG. 2 is a side view of FIG. 1 (a view of FIG. 1 as seen from obliquely above to the left). In FIG. 1, for simplicity of the drawing, the spout 4, the first blower 82, etc. shown in FIG. 2 are omitted. In the present embodiment, an embodiment in which the loose tea device 10 of the present invention is applied to a tea rolling furnace 9 that dries by forcibly ventilating hot air, also referred to as a net-type dryer, will be described as an example.

[0029] The tea leaves heat-steamed by a heat-steaming machine are cooled by being scattered by a blowing tank 4 or a loose tea leaf device 10, and then dried by a powdered green tea furnace 9. Specifically, as shown in FIG. 2, the tea leaves heat-steamed by a heat-steaming machine (not shown) are put into a first hopper 81 and blown into the blowing tank 4 by a first blower 82. The blowing tank 4 is formed by processing a net with fine meshes into a bag shape, and is suspended and installed by a hanging member 25 provided in the loose tea leaf device 10. The tea leaves blown into the blowing tank 4 rise to near the ceiling and then naturally fall into a second hopper 83, and are blown into the loose tea leaf device 10 by a second blower 84. The second blower 84 corresponds to an example of a blowing means. The tea leaves blown into the loose tea leaf device 10 rise to near the ceiling, and the naturally falling tea leaves are put in a state where they are spread without overlapping a conveyor such as a net conveyor (not shown) of the powdered green tea furnace 9. In this way, by repeatedly blowing the tea leaves in the blowing tank 4 and the loose tea leaf device 10, the steamed dew adhering to the tea leaves is removed, and the overlapping tea leaves and the bent tea leaves are promoted to unfold. In the present embodiment, an example in which one blowing tank 4 is provided before the loose tea leaf device 10 has been described, but two or more blowing tanks 4 may be provided, or in some cases, the blowing tank 4 may be omitted.

[0030] The tea leaves put into the conveyor (not shown) are dried in the process of being horizontally conveyed inside the powdered green tea furnace 9 as shown by the arrow in FIG. 2. In the present embodiment, the loose tea leaf device 10 of the present invention is used for a continuous convection heat transfer type powdered green tea furnace 9 that dries the tea leaves on a horizontally moving conveyor by forced ventilation of hot air, but the loose tea leaf device 10 of the present invention may also be used for a powdered green tea furnace that dries by radiative heat transfer and natural convection heat transfer.

[0031] Next, with reference to FIGS. 3 and 4 as well, the specific configuration of the loose tea leaf device 10 of the present invention will be described. FIG. 3 is a front view of the loose tea leaf device 10 shown in FIG. 1. Note that FIG. 3 corresponds to a view of the loose tea leaf device 10 in FIG. 1 seen from the upper right obliquely. FIG. 4 is a cross-sectional view taken along line A-A of the loose tea leaf device 10 shown in FIG. 3.

[0032] As shown in FIGS. 1 to 4, the loose tea device 10 has a cage 2 that defines a blowing space S (see FIGS. 2 and 4) for blowing up the tea leaves blown and input by the aforementioned second blower 84. The cage 2 is configured in a rectangular parallelepiped shape, and as shown in FIGS. 3 and 4, it has a lower body portion 23 provided at the lower end portion, a frame-shaped frame 21 provided on the lower body portion 23, a wire mesh 21a stretched on the frame 21, and a net unit 3.

[0033] An input port 23a through which the tea leaves are blown and input by the aforementioned second blower 84 is formed in the lower body portion 23. As shown in FIG. 4, a guide portion 232 for guiding the tea leaves blown and input obliquely upward into the blowing space S is provided. In addition, inspection windows 231 made of glass plates or the like are provided on the left and right side surfaces of the lower body portion 23 facing the input port 23a.

[0034] As shown in FIG. 4, the net unit 3 is provided in an upper part of the surface of the cage 2 facing the input port 23a. That is, the net unit 3 is provided on the surface facing the blowing direction of the second blower 84 (see FIG. 2). A wire mesh 21a is stretched on the lower part of the net unit 3 and the frames 21 of the other three sides. That is, the rectangular tube-shaped side surface portion of the cage 2 has air permeability. The mesh size of the wire mesh 21a is set to a size (for example, about 40 mesh) that can effectively suppress scattered tea dust and the like in order to prevent the deterioration of the environment in the factory while ensuring sufficient air permeability. In this embodiment, the ceiling portion 22 of the cage 2 is composed of a plate material having no air permeability, but a wire mesh may be arranged instead of the plate material to have an air-permeable mode.

[0035] Next, with reference to FIGS. 4 and 5, the configuration of the net unit 3 will be described in detail. FIG. 5 is an explanatory view showing the main part of the net unit 3 disassembled.

[0036] As shown in Fig. 5, the mesh unit 3 includes a pair of chains (endless members) 31, 31 each configured in an endless shape and disposed on both sides in the width direction, a mesh body 7 spanned in the width direction with respect to the pair of chains 31, 31, and a pair of upper and lower drive members 32, 32 (travel mechanism) for circulating the pair of chains 31, 31. Here, the width direction refers to the direction orthogonal to the direction in which the tea leaves introduced from the loose tea device 10 into the ground tea furnace 9 are conveyed inside the ground tea furnace 9 (the direction orthogonal to the plane of Fig. 2).

[0037] The mesh body 7 may be composed of a single mesh body, but the mesh body 7 of the present embodiment is composed of two mesh bodies, a first mesh body 7A and a second mesh body 7B. In Fig. 5, the back side of the second mesh body 7B corresponds to the blowing space S of the basket 2. As shown by the straight arrows in Figs. 4 and 5, the mesh body 7 circulates between a position facing the blowing space S and a position exposed outside the basket 2 as the pair of chains 31, 31 circulate. Hereinafter, the direction in which the mesh body 7 circulates will be described as the circulation direction. Note that the circulation direction may be opposite to the direction shown by the straight arrows in Figs. 4 and 5.

[0038] As shown in Fig. 4, in the present embodiment, the upper part of the mesh body 7 is blocked by a wall plate 332 continuous from the ceiling part 22, and the lower part of the mesh body 7 is blocked by a detachable lid 331. That is, the lid 331 is detachably provided outside the orbit in which the mesh body 7 circulates and corresponds to an example of a blocking member that prevents ventilation from the mesh body 7. In the present embodiment, by removing the lid 331, the lower part located outside the mesh body 7 (the lower part of the first mesh body 7A in Fig. 4) is exposed outside the basket 2. Note that the lid 331 is not an essential component, and the wall plate 332 can also be omitted.

[0039] A plurality of crossbars 311 are bridged across a pair of chains 31, 31 at a predetermined interval in the circulating movement direction. The first net body 7A and the second net body 7B are attached to the crossbars 311, for example, by screwing. That is, the first net body 7A and the second net body 7B are spanned in the width direction with respect to the pair of chains 31, 31 by being attached to the crossbars 311. In the state shown in FIG. 5, the second net body 7B is attached to four crossbars 311 on the blowing space S side at intervals in the circulating movement direction, and the first net body 7A is attached to four crossbars 311 on the side opposite to the blowing space S. That is, a predetermined gap is formed between the first net body 7A and the second net body 7B (the upper end portion and the lower end portion in FIGS. 4 and 5).

[0040] The net body 7 of the present embodiment is made of a net of synthetic resin fibers or natural material fibers. The first net body 7A is composed of a net having substantially the same mesh as the wire net 21a. On the other hand, the second net body 7B is composed of a net having a larger mesh than the first net body 7A. For example, the mesh of the second net body 7B is set from the viewpoint of how much fine powder is mixed with the tea leaves put into the matcha furnace 9.

[0041] Each of the pair of upper and lower drive members 32, 32 is composed of a pair of sprockets 321, 321 arranged on both sides in the width direction and a rod 322 connecting these pair of sprockets 321, 321. As shown in FIGS. 3 and 5, a handle 323 is provided on one of the sprockets 321 of the lower drive member 32. For example, when an operator climbs the ladder 26 and rotates the handle 323, the lower drive member 32 rotates, and the pair of chains 31, 31 circulate while the upper drive member 32 also rotates. Thereby, the net body 7 circulates. For the sake of convenience of explanation, in FIG. 5, the state where the handle 323 shown in FIG. 3 is attached to the sprocket 321 on the opposite side is shown.

[0042] Also, as shown in FIGS. 1, 2, 4, etc., a bifurcated chute 34 is provided at a position below the mesh body 7 or the like, and a hose 341 connected to the lower end of the chute 34 extends to a collection bag 342. These chute 34, hose 341, and collection bag 342 correspond to an example of a collection means. Thereby, the fine powder or the like that has fallen from the gap between the lower end portions of the first mesh body 7A and the second mesh body 7B described above with reference to FIG. 5 is accommodated in the chute 34 and then collected in the collection bag 342 via the hose 341.

[0043] Next, with reference to FIGS. 2 and 4, the flow of tea leaves from when they are put into the loose tea device 10 until they are put into the green tea roasting furnace 9 will be described. The state shown in FIGS. 2 and 4 is, as described above, a state in which the second mesh body 7B with a large opening is arranged at a position facing the blowing space S.

[0044] The tea leaves blown obliquely upward from the inlet 23a into the blowing space S by the second blower 84 (see FIG. 2) are blown up to the vicinity of the ceiling portion 22. In the present embodiment, since the mesh unit 3 is provided on the surface facing the blowing direction, the blown tea leaves are likely to collide with the second mesh body 7B, and fine powder or the like smaller than the opening of the second mesh body 7B passes through the second mesh body 7B as shown by the dashed arrow, falls into the chute 34, and is collected in the collection bag 342 through the hose 341. That is, by setting the opening of the second mesh body 7B, it is possible to adjust how much fine powder is collected and how much fine powder is mixed into the tea leaves put into the green tea roasting furnace 9. The tea leaves that could not pass through the second mesh body 7B or the tea leaves that did not collide with the second mesh body 7B fall naturally and are put into the green tea roasting furnace 9 in a state of being spread out without overlapping a conveyor such as a net conveyor (not shown).

[0045] When clogging such as tea dust occurs in the second screen body 7B, climb the ladder 26 or get onto the powdered tea furnace 9, and rotate the handle 323 with the lid 331 removed. As a result, the second screen body 7B circulates and moves to a position where it is exposed outside the cage 2. At this time, for example, if air is blown using an air blower gun, the clogging of the second screen body 7B is removed, and the removed tea dust etc. can also be collected in the collection bag 342. Also, at this time, in addition to removing the clogging of the second screen body 7B, removal of the attached tea leaves etc. can also be performed. Then, after rotating the handle 323 to circulate and move the second screen body 7B to a position facing the blowing space S and attaching the lid 331, the operation may be restarted. Of course, it is also possible to operate the first screen body 7A in a state where it faces the blowing space S.

[0046] The drive member 32 is not limited to the mode of being rotated manually, and may also be a mode of being rotated by a motor or the like. Also, a removal member 35 composed of an air blowing device, a brush, etc. is provided at the lower end portion of the path through which the screen body 7 circulates, for example, the path indicated by the broken-line square in FIG. 4, and while automatically circulating and moving the screen body 7 by a motor or the like, it is also possible to remove clogging etc. of the screen body 7.

[0047] As described above, according to the loose tea device of the present invention, it is possible to easily clean the screen body 7 of the screen unit 3 provided inside the cage 2, particularly on the surface facing the blowing direction.

[0048] The present invention is not limited to the above-described embodiments and can be variously modified within the scope described in the claims. For example, in the above-described embodiment, an example in which predetermined gaps are formed at the upper end portion and the lower end portion between the first net body 7A and the second net body 7B has been described, but a mode in which a predetermined gap is formed only at the lower end portion may be used. Further, it is also possible to connect a single net body 7 in a ring shape so that no gap is generated. Furthermore, in the net body 7, a third net body or a fourth net body having different mesh openings may be arranged, or a net body 7 in which the size of the mesh openings continuously changes may be used, and the size of the fine powder or the like to be collected may be finely adjusted. On the other hand, it is not essential to make the mesh openings different. For example, the mesh openings of the first net body 7A and the second net body 7B may be set to be the same. Furthermore, in the above-described embodiment, a mode in which the net unit 3 is provided in an upper portion of a surface of the cage 2 facing the charging port 23a has been described, but the entire side surface of the cage 2 may be constituted by the net unit 3, or three or two sides of the side surface of the cage 2 may be constituted by the net unit 3.
