FIG. 1 is an explanatory view showing an embodiment of the present apparatus. FIG. 2 is an explanatory view showing an embodiment of this apparatus. FIG. 3 is an explanatory view showing an embodiment of this apparatus. FIG. 4 is an explanatory view showing an embodiment of this apparatus.

  FIG. 1 shows the apparatus of the present invention. In the tea factory, the fresh tea leaves A are received, temporarily stored in a fresh tea leaf container (not shown), and sequentially transported to the tea making machine 1 by a transport device (not shown) to perform steaming heat treatment. At this time, if a certain amount of fresh tea leaves A are not added to the tea steamer 1, steaming unevenness occurs. Therefore, using the fresh tea leaf supply device 6, the tea leaves are fed to the tea leaf inlet 2 of the tea steamer 1 by a certain amount. ing. The tea-making steamer 1 generally includes a rotary drum-type steamer and a band-type steamer, but any of them may be used as long as it is a tea-making steamer. Steam generated in a boiler (not shown) is supplied to the steam supply port 5 of the tea making machine 1 through the steam supply pipe 4. In the tea-making steamer 1, steam is applied to the supplied raw tea leaves A, and steaming heat treatment is performed to inactivate the oxidase. Usually, steaming heat treatment is performed for about 60 to 120 seconds, and about 300 to 400 g of steam is supplied to the tea making machine 1 per 1 kg of fresh tea leaves. The tea leaves B that have been subjected to the steaming heat treatment are discharged from the tea leaf discharge port 3 of the tea making machine 1 onto the conveying device 7 and are transported to the next tea making device (not shown) for tea making. The steam C that is no longer needed for the tea leaves A is discharged from the steam discharge port 8 to the outside of the tea making machine 1. The steam C contains aroma components of fresh tea leaves A.

  A steam recovery hood 11 is provided so that the steam C can be recovered on the steam outlet 8 of the tea-making steamer 1, and a suction fan 12 is provided to efficiently recover the steam C in the steam recovery hood 11. The steam C collected in the steam recovery hood 11 passes through the duct 15 and is transported from the steam inlet 13A to the cyclone 13 which is a condensed water separation means. In the cyclone 13, the steam is swirled, and the water in the steam is separated as condensed water by the centrifugal force generated by the swirling flow. Specifically, a part of the steam is cooled by heat dissipation to become condensed water, and centrifugal force is applied to the condensed water and blown off to the outside. The blown-off condensed water travels down on the inner wall surface of the cyclone 13 by gravity. To do. The steam separated from the condensed water is discharged from the steam outlet 13B. The separated condensed water is stored in the storage tank 14 which is a storage means from the condensed water discharge port 13D at the lower part of the cyclone 13. When condensed water accumulates in the storage tank 14, the condensed water is transferred from the condensed water discharge port 14 </ b> D of the storage tank 14 to the transport tank 16.

  This condensed water contains aroma components of fresh tea leaves and a fresh scent such as green leaf alcohol. The scent of condensed water is the same as that of tea plantations.

  A transmission-type sensor 30 is installed in the vicinity where the fresh tea leaves A are fed from the fresh tea leaf supply device 6 to the fresh tea leaf inlet 2 of the tea steamer 1. This sensor 30 checks whether or not fresh tea leaves A are present. When this sensor 30 senses the presence of fresh tea leaves A, it means that the fresh tea leaves A are being supplied from the fresh tea leaf supply device 6 to the tea making machine 1, and at this time, the suction fan 12 is activated. .

  Regarding the activation of the suction fan 12, the sensor 30 may be activated immediately after sensing the presence of fresh tea leaves A, but the suction fan 12 is activated after a predetermined time from when the sensor 30 starts sensing the presence of fresh tea leaves A. It is more efficient to set it to do so. In the tea-making steamer 1, normally, the steam is supplied before the fresh tea leaves A are started to be supplied, the steam is stably supplied, and the supply of fresh tea leaves is started after other preparations are completed. Therefore, the supply of fresh tea leaves and the suction fan 12 work together to efficiently collect only the steam containing the fragrance component without collecting unnecessary steam or air that does not contain the fragrance component of the fresh tea leaf. it can. Furthermore, when experimented, the fresh scent of fresh tea leaves has an unpleasant scent. Therefore, if the suction fan 12 is set to start several minutes after the start of sensing the presence of the fresh tea leaves A, the unpleasant scent does not have to be collected.

  If the sensor 30 no longer senses the presence of fresh tea leaves A, it means that the supply of fresh tea leaves A from the fresh tea leaf supply device 6 to the tea steamer 1 is terminated, so the suction fan 12 is stopped. Thus, it is not necessary to collect | recover the vapor | steam and air which do not contain the aromatic component of fresh tea leaves because the suction fan 12 stops automatically.

  The flow of collecting aroma components of fresh tea leaves will be described. When the fresh tea leaves A are put into the fresh tea leaves supply device 6 and started to be fed into the tea steamer 1 to which steam is supplied in advance from a boiler (not shown), the sensor 30 senses the presence of fresh tea leaves A and for a predetermined time. After the elapse of time (for example, 0 minutes, 1 minute, 2 minutes, 3 minutes, 4 minutes, etc.), the suction fan 12 is started. The suction fan 12 adjusts the suction amount according to the amount of steam. The fresh tea leaves A are fed into the tea making machine 1 from the fresh tea leaves inlet 2, steam-heated with steam in the tea making machine 1, discharged to the tea leaf outlet 3, and transferred to the next tea making machine (not shown) by the transfer device 7. Carried. The steam C obtained by steaming the fresh tea leaves A contains aroma components of fresh tea leaves. The steam C is discharged from the steam discharge port 8, accumulates in the steam recovery hood 11, is sucked by the suction fan 12, passes through the duct 15, and separates condensed water in the cyclone 13. This condensed water contains aroma components of fresh tea leaves. Condensed water is put into the storage tank 14, and is filtered by a filter or the like, transferred to the transport tank 16 as necessary, and transported. The steam from which condensed water has been separated by the cyclone 13 is discharged from the steam discharge port 13B. This is continued while fresh tea leaves A are being fed into the tea steamer 1 (while the sensor 30 senses fresh tea leaves A). When charging of the tea leaves A into the tea making machine 1 is completed, the sensor 30 stops detecting the tea leaves A and stops the suction fan 12.

  Next, the case where two cyclones are provided will be described with reference to FIGS. First, steam is sent to the steam inlet 13 </ b> A of the cyclone 13. The condensed water separated by the cyclone 13 is stored in the storage tank 14 from the condensed water discharge port 13D. The steam after the condensed water is separated from the steam in the cyclone 13 is discharged from the steam outlet 13B, and is sent to the steam inlet 18A of the next cyclone 18 through the duct 17. Similarly in the next cyclone 18, the condensed water is separated from the steam. An exhaust steam cylinder 18C is provided at the tip of the steam outlet 18B of the cyclone 18, and a backing plate 18E is provided on the exhaust steam cylinder 18C. When the steam in the exhaust gas is cooled and becomes condensed water, the exhaust gas enters the cyclone 18. To be able to return. The condensed water separated by the cyclone 18 is discharged from the condensed water discharge port 18D to the storage tank 14, mixed with the condensed water discharged from the cyclone 13, and stored. In this embodiment, two cyclones are provided, but the same applies to three or more cyclones. The steam outlet 18B does not have to be branched, but the bifurcated direction improves the recovery rate of the condensed water. Further, the recovery rate is further improved by providing a plurality of the contact plates 18E in the exhaust pipe 18C.

  Since not only condensed water but also steam may be discharged from the cyclones 13 and 18 to the storage tank 14, the storage tank 14 is provided with a steam discharge port 14B to discharge the steam. The steam discharge port 14B is provided with a steaming tube 14C, and the steaming tube 14C is provided with a contact plate 14E. The contact plate 14E improves the condensate recovery rate.

  If the storage tank 14 is placed on the lifting / lowering means 20 whose height can be adjusted, the height of the storage tank 14 can be changed depending on the size of the transport tank 16. If the elevating / lowering means 20 is provided with moving means (rollers or the like), it can be easily added to the existing tea-making machine 1, and the arrangement can be changed as necessary.

  When the spot cooler 19 is arranged and the air around the cyclones 13 and 18 and the storage tank 14 is cooled, a steam cooling effect can be obtained, and the condensate recovery rate is improved. In the present embodiment, the spot cooler 19 is disposed, but a cooling fan or a blower fan may be used as long as the surrounding air can be cooled.

  By making the ducts 15 and 17 detachable by a clamp type and providing the water washing ports 21A, 21B, 21C, and 21D, cleaning becomes easy and the apparatus can be kept clean.
