DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The tea leaf production line according to the present embodiment is a line for producing kettle roasted tea, and is composed of various devices arranged in the tea factory 1, as shown in FIG.
[0016]
As shown in the figure, this production line includes a feeder 2, a blue killing machine 3, a cooling powder remover 4, a twisting machine 5 as a kneader, a roughing machine 6 as a drying machine, and a twisting machine. Mainly composed of a machine 7 and a dryer 8, these apparatuses are connected by various conveying means 9 to 23. That is, the tea leaves that have passed through each process are automatically conveyed to the next process by various conveying means 9 to 23 and subjected to desired processing.
[0017]
The leaf feeder 2 carries the fresh tea leaves into the blue killing machine 3 from the fresh leaf container A (consisting of the fresh leaf container a and the fresh leaf flow meter b) for accommodating fresh tea leaves transported from a tea plantation or the like. As shown in FIG. 2, it extends from the floor of the tea factory 1 to the inlet 3 a of the blue killing machine 3 while being inclined at a predetermined angle. The leaf feeder 2 is provided with a cutting device (not shown) for removing the cut leaves contained in the raw tea leaves, and mixing of the cut leaves into the blue killing machine 3 is suppressed. . This makes it possible to obtain a higher quality roasted tea.
[0018]
That is, since the cut leaves are easily burned by heating, if the cut leaves are mixed into the blue killing machine 3 and are subjected to the blue killing process, they are burned by the heat during the blue killing process, and the flavor of the whole tea leaves is impaired, and the quality deteriorates. There is a risk of it. However, the mixed powder can be removed by the cooling powder remover 4 in the subsequent process, but the state in which the powder in the blue killing machine 3 is mixed cannot be avoided, and the mixing adversely affects the aroma of the tea leaves. There is a risk of it.
[0019]
As shown in FIG. 2, the blue killing machine 3 has a metal cylindrical blue killing cylinder 3c whose side is sealed, and the blue killing cylinder 3c rotates around its axis while being inclined, and is charged from the charging port 3a. The raw tea leaves thus taken are guided to the outlet 3b. Further, a furnace 3e having a gun-type burner 3d is formed below the blue killing drum 3c, and is configured to be heated from the outer peripheral surface of the rotating blue killing drum 3c. By heating through the blue killing body 3c, raw tea leaves can be roasted, the activity of the oxidase in the raw tea leaves can be eliminated, the blue odor can be eliminated, and a flavor peculiar to kettle roasted tea can be imparted.
[0020]
After the blue killing process by the blue killing machine 3 is completed, the tea leaves discharged from the outlet 3b are transported to the cooling powder remover 4 by the transport means 9 and 10. Such a cooling powder remover 4 has a rotating net cylinder, and cools the adhering powder such as burnt by removing the tea leaves after the blue-killing treatment through the net cylinder. By passing through this cooling powder remover 4, there is no burn or the like, and by lowering the product temperature, the color is improved and a high quality tea leaf can be obtained.
[0021]
The tea leaves discharged from the cooling powder remover 4 are conveyed to the twisting machine 5 by the conveying means 11 and 16 as shown in FIG. The twisting machine 5 is for making the water in each part of the tea leaves (mainly the inside and the surface part of the tea leaves) uniform by rotating while pressing the tea leaves. A specific configuration of the twisting machine 5 is substantially the same as that of the later-described twisting machine 7. For example, as shown in FIG. 4, a grid 24 on which tea leaves can be placed, and an upper surface of the grid 24. A rotatable bowl 25, a rolling board 26 disposed in the bowl 25 and rotating on the board 24 in conjunction with the bowl 25, and applying a load to the board 24 It is mainly composed of a weight 27 that can be applied and the load can be adjusted to adjust the stagnation pressure on the tea leaves.
[0022]
The adjustment of the load by the weight 27 is different between the twisting machine 5 and the twisting machine 7, and the setting of the stagnation pressure by the twisting machine 5 is larger than the stagnation pressure by the twisting machine 7. As a result, the tea leaves flowing through the production line are strongly squeezed by the twisting machine 5, and then reach the twisting machine 7 through the roughing machine 6, where they are squeezed weaker than the twisting machine 5. That is, the purpose of the twister 5 is to pressurize the tea leaves and squeeze out the core water (internal moisture) of the tea leaves to make the water uniform. On the other hand, in the twister 7, the tea leaves are tightened. In order to adjust the shape of the tea leaves, it is intended to apply a massage pressure to the tea leaves.
[0023]
Further, as shown in FIG. 5, a plurality of hills 24a extending in a circular arc shape from the center C are fixed to the upper surface of the grid 24 in the twister 5 by welding or the like. Similarly, a plurality of hills 24a ′ extending in an arc shape from the center are formed on the upper surface of the grid 24 ′ of the twisting machine 7, and the cross-sectional shape thereof is shown in FIG. The board of machine 7 is denoted by reference numeral 24 ', and the hill formed there is denoted by reference numeral 24a').
[0024]
On the other hand, FIG. 6A shows a cross-sectional view of the hill 24a in the twisting machine 5. As can be seen by comparing FIG. 6A and FIG. 5 and the twisting machine 7 have different diameters D and d. That is, the diameter D of the hill 24a in the twisting machine 5 is set to be larger than the diameter d of the hill 24a 'in the twisting machine 7, and the stagnation pressure by the twisting machine 5 is larger than the stagnation pressure by the twisting machine 7. It is configured as follows.
[0025]
When the diameter of the hill is increased, the friction between the hill and the tea leaf increases, and the stagnation pressure increases. There is a risk of it. In order to avoid such a problem, it is preferable that the twisting machine 5 forms the hills 24a adjacent to the twisting machine 7 wider than 24a 'so as to ensure the fluidity of the tea leaves on the board 24.
[0026]
With the configuration as described above, the twister 5 serving as a kneader for making the moisture of the tea leaves uniform before the rough kneader 6 and the twister 7 is disposed. The tea leaves can be processed well, and the drying efficiency of the tea leaves after the next step can be improved. Therefore, it is possible to always obtain high quality roasted tea for various dry tea leaves.
[0027]
In the present embodiment, the twisting machine 5 having the above-described configuration is provided, but the tea leaves are pressurized to make the water in each part of the tea leaves uniform (in the present invention, this action can be exerted on the tea leaves). As long as it can be called a “kneader”, it may be replaced with another configuration. For example, a continuous twisting machine called a roller type (having a roller that rotates in a cylindrical member, and in the process of allowing the tea leaf to pass through the cylindrical member while rotating the roller, It is also possible to use one that is strongly pressed between the surface and the outer peripheral surface of the roller.
[0028]
By the way, the above-described twisting machine 5 is of a fluid type and is configured to sequentially discharge tea leaves that have been processed while processing the tea leaves that are sequentially sent from the conveying means 11. A certain amount of tea leaves are processed all at once, and discharged after a predetermined time. The twisting machine 7 is for applying a kneading pressure to the tea leaves so as to tighten the tea leaves and adjust the shape.
[0029]
Here, the twisting machine 7 according to the present embodiment is controlled so as to reverse the bowl 25 for a predetermined time while reducing or releasing the kneading pressure on the tea leaves after the bowl 25 is rotated forward for a predetermined time. For example, when the process time is 30 minutes, the bowl 25 is rotated in the normal direction for 9 minutes while applying a predetermined stagnation pressure on the squeezing platen 26, and then the basin 25 is adjusted while reducing or eliminating the stagnation pressure by adjusting the weight 27. Is reversed for 1 minute and the process is repeated 3 times. As described above, the process of reversing the pot 25 while reducing or canceling the mastication pressure solves the balls (tea leaf lump) generated during the twisting, so that the shape of each tea leaf can be adjusted substantially uniformly. is there. Moreover, by passing through the process by the twisting machine 7, the product tea with favorable extractability of a required component can be obtained.
[0030]
It should be noted that the scissors platen 26 and the bowl 25 in the scissor 7 are connected by a rotation prevention tool such as a chain to suppress their relative rotation, or the bottom surface of the scissor plate 26 (the surface facing the scissors 24 '). A plurality of convex portions may be formed on the tea leaves so that the twisting action can be exerted more reliably on the tea leaves. Moreover, you may make it soften a tea leaf by supplying a predetermined amount of water on the grid 24 in the twisting machine 7 during the twisting.
[0031]
The tea leaves that have been subjected to the twisting process by the twisting machine 5 are dropped onto the transporting means 17 and then transported to the roughing machine 6 as a paddy dryer through the transporting means 18, 12, and 19 (see FIG. 3). Such a roughing machine 6 heats the tea leaves with hot air while spreading the leaves and evaporates the water in the tea leaves by compression and friction, and supplies hot air into the roughing machine 6 as shown in FIG. And a hot air passage 6b for connecting the hot air furnace 6a and the inside of the roughing machine 6 to each other.
[0032]
As shown in FIG. 7, the roughing machine 6 includes a coffee room 6aa in which tea leaves are accommodated, a rotary shaft 6ab that can be rotated through the coffee room 6aa, and a coffee room formed on the rotary shaft 6ab. A leaf crust 6ac for stirring the tea leaves in 6aa and a grip 6ad formed on the rotation shaft 6ab for holding the tea leaves in the cocoon chamber 6aa are provided, and the rotation shaft 6ab is driven to rotate. While the tea leaves on the bottom surface of the tea room 6aa are spread and stirred, the water content of the tea leaves is evaporated, and the tea leaves are pressed and swallowed between the hand 6ad and the bottom surface of the tea room 6aa.
[0033]
In particular, in the handle 6ad in the present embodiment, an uneven shape m made of an elastic member or the like is formed at a portion facing the inner peripheral surface of the bag chamber 6aa. The uneven shape m can surely exert a squeezing action on the tea leaves, soften the tea leaves during the rough kneading process, and avoid problems such as leaf breakage even when processing tea leaves with less moisture. be able to.
[0034]
Here, in the hot air passage 6b connecting the roughing machine 6 and the hot air furnace 6a, as shown in FIG. The humidifier 28 is for humidifying the hot air flowing from the hot air furnace 6a into the coffin room 6aa of the roughing machine 6 to adjust the moisture in the tea leaves in the coffin room 6aa. Thereby, the dry-up phenomenon of tea leaves can be prevented and high-quality product tea can be obtained.
[0035]
Moreover, the following are mentioned as another means (moisture adjusting means of another form) for adjusting the water | moisture content in the tea leaf in the cocoon chamber 6aa. For example, if a predetermined amount of mist, steam, water, or hot water is directly supplied to the cocoon chamber 6aa, the tea leaves in the rough koji process can be softened, and even when processing tea leaves with less moisture, the leaf breakage, etc. Can be avoided.
[0036]
Furthermore, in order to avoid excessive evaporation of the surface moisture of the tea leaves during the rough koji process, stirring of the tea leaves by the leaf sand 6ac is suppressed, or the amount of hot air supplied by the hot air furnace 6a is reduced. The surface moisture of the tea leaves can be prevented from evaporating more than necessary. Among these, as a method for suppressing the stirring of tea leaves by the leaf roughness 6ac, the number of claws of the leaf roughness 6ac is reduced than usual (for example, about 3), or the attachment angle of the leaf roughness 6ac to the rotating shaft 6ab is variable. Is effective.
[0037]
On the other hand, as a method of reducing the supply amount of hot air, an escape window that can be opened to the outside air is formed in a part of the hot air passage 6b (including a wind guide (not shown) that leads from the hot air passage 6b to the coffin chamber 6aa). A part of the hot air passing through the hot air passage 6b may be escaped from the escape window, or the rotational speed of a blower (not shown) provided in the hot air furnace 6a is reduced to reduce the hot air itself to be sent. May be.
[0038]
Furthermore, in order to soften the tea leaves in the cocoon chamber 6aa, the body member constituting the cocoon chamber 6aa is made of metal, and the body member is heated by electric heat, or a burner is formed from below the body member. You may comprise so that it may heat by. By configuring in this way, when processing tea leaves with low moisture, drying is performed by heat instead of wind, so the moisture inside the tea leaves will come out to the surface moderately, and the moisture of the tea leaves will be dried more than necessary. The shape of tea leaves can be improved.
[0039]
Further, the roughing machine 6 is of a fluid type, and is configured such that tea leaves are sequentially introduced from the upper inlet, and discharged from the lower outlet sequentially after the roughing process has been completed. However, instead of this, it may be a batch type (configured so that a certain amount of tea leaves are processed in a lump and discharged after a lapse of a predetermined time). In addition, instead of the roughing machine 6, another rice drying machine (such as a medium grinder or a middle rice bowl machine, which is heated with hot air while spreading the leaves of the leaves, between You may make it arrange | position the thing which evaporates the water | moisture content in a tea leaf.
[0040]
The tea leaves that have undergone the rough kneading process by the rough kneader 6 are dropped onto the conveying means 20 disposed below the rough kneading machine 6 and conveyed to the twisting machine 7 through the conveying means 21. The twister 7 is a batch type as described above, but may be a flow type instead. In the case of such a flow type, it becomes impossible to exert the tea leaf releasing action by the forward and reverse operations of the pot 26, but the tea leaf releasing action can be exerted in this step by adopting the following configuration. .
[0041]
That is, as shown in FIG. 10, flow type twisting machines 7a to 7c are arranged in series and connected by conveying means h1 to h3 such as a vibration conveyor, and are conveyed between the respective twisting machines. Disassembling means 29a to 29c for unraveling the tea leaves can be respectively disposed in the means. Further, as shown in the figure, the number of the twisting machines arranged in series is not limited to three, but a plurality of twisting machines may be sufficient, and the capacity of the fluid type twisting machine arranged from the upstream to the downstream of the production line is gradually increased. It may be made smaller. In addition, it is preferable to use a bead unrolling device, which will be described later, as the unwinding means disposed in each conveying means.
[0042]
The tea leaves that have been subjected to the twisting process by the twister 7 are dropped onto the transporting means 22 and then transported to the dryer 8 through the transporting means 23, 13, 14, and 15. The dryer 8 is for drying tea leaves until the water content can withstand storage, and is located in the final process of a series of kettle roasted tea production lines. The tea leaves that have undergone the drying process by the dryer 8 are conveyed to a subsequent bagging process or the like.
[0043]
According to the tea leaf production line, the line is composed in the order of the blue killing machine 3, the cooling powder removing machine 4, the twisting machine 5, the roughing machine 6, the twisting machine 7 and the dryer 8. Thus, the roasted tea can be obtained while reducing the line cost. In particular, the twisting machine 7 is disposed in the subsequent process of the rough kneading machine 6, and a product tea with good extractability of necessary components can be obtained.
[0044]
Here, as shown in FIG. 9, the ball sorting device 30 and the ball unrolling device 31 may be arranged as a pair in a process preceding the dryer 8. Among these, the ball sorting device 30 is for sorting balls (tea leaf lump) generated during the manufacturing process. For example, as shown in FIG. In addition, the balls can be selected by transferring them to the dryer 8 side and blowing the balls remaining on the sieve 30a to the cyclone 32 side by the blower 30b.
[0045]
The bead unrolling device 31 is for unrolling the balls that have fallen from the cyclone 32. For example, the unrolling device 31 is composed of a device that unwinds the balls by shearing with a cutter or the like. The product is conveyed to the dryer 8. Note that the configurations of the ball sorting device 30 and the ball unrolling device 31 are not limited to those described above, and other configurations may be used as long as they can sort and unravel the balls.
[0046]
Thus, by incorporating a ball sorting device and a ball unrolling device as a pair into the line, the balls produced by the roughing machine and the twisting machine can be effectively unwound and a higher-quality kettle roasted tea can be obtained. . In addition, the arrangement | positioning location of a ball | bowl sorter and a ball unroller is not limited to the front process of the dryer 8 as mentioned above, You may make it arrange | position in a back process. In this case, it is preferable that the tea leaves that have been unwound by the ball unrolling device are again put into the dryer 8 and dried.
[0047]
Although the present embodiment has been described above, the present invention is not limited to this. For example, the various transport means 9 to 23 can be replaced with other forms, and transported to the next process by an operator. It may be a line having a configuration to That is, if the line is constituted in the order of the blue killing machine 3, the cooling powder removing machine 4, the twisting machine 5, the roughing machine 6, the twisting machine 7 and the dryer 8, it is sufficient to achieve the effects of the present invention.
[0048]
Moreover, in the said embodiment, although it applies to the production line for obtaining kettle roasted tea, it changed the blue-killing processing method by the blue killing machine 3, etc., and the kettle with the unique flavor similar to kettle roasted tea You may make it apply to the manufacturing line for obtaining fried-style tea leaves.
