Description
Technical Field
[0001] The utility model relates to the technical field of tea storage, in particular to a Pu'er tea fermentation room. Background Art
[0002] Pu'er tea is made from fresh leaves of Yunnan large-leaf tea trees, which are formed by special steaming and pressing, and then stored for a certain period of time. The storage method of Pu'er tea has an important impact on the characteristics and taste of the tea. The two most common storage methods are "wet storage" and "dry storage".
[0003] Wet warehouse Pu'er tea is stored in a wet warehouse with a relative humidity of more than 80% to make it ferment quickly. Therefore, it has the advantage of faster aging, but in this process, mold sometimes occurs, and the quality and flavor may vary depending on the storage conditions and are difficult to control. Dry warehouse Pu'er tea is stored in a warehouse with a relative humidity of less than 80%, allowing it to age slowly and naturally, transforming into a "mature and fragrant" quality. Its aging speed is slower, but the quality is higher. Therefore, at present, "dry warehouse" is the mainstream storage method.
[0004] In the current fermentation rooms that use the "dry storage" method for aging, the regulatory power of nature is usually ignored, and only equipment is used for regulation, which consumes a lot of energy and has high storage costs. Utility Model Content
[0005] The utility model aims to provide a Pu'er tea fermentation room, aiming to improve the problem that the existing fermentation room only uses equipment regulation and the storage cost is too high.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A Pu'er tea fermentation room includes a tea warehouse body, and also includes: an outer wall, which is arranged around the tea warehouse body to form an isolation passage, a first air inlet is provided on the north side of the outer wall, a first air outlet is provided on the south side of the outer wall, and a first fan is provided on the first air outlet; the tea warehouse body includes a plurality of storage rooms, each of which is provided with a second air inlet and a second air outlet corresponding to the isolation passage on the east / west side, and a second fan is provided on the second air outlet.
[0008] Preferably, the second air inlet is located on the north side of the second air outlet.
[0009] Preferably, in each storage chamber, the second air inlet and the second air outlet are located on the same side, and a spoiler for separation is provided between the second air inlet and the second air outlet in the storage chamber.
[0010] Preferably, the wall of the second air outlet is concave relative to the storage chamber to form a concave wall.
[0011] Preferably, the second fan is installed on the outer side of the inner concave wall; and the first fan is installed on the inner side of the isolation channel.
[0012] Preferably, there are four storage chambers distributed in a cross shape, and the storage years defined in each storage chamber decrease / increase in clockwise / counterclockwise direction.
[0013] Preferably, four cross-distributed ventilation windows are provided at the cross junctions of the four storage chambers.
[0014] Preferably, the east and west sides of the outer wall are provided with enclosed skylights, and the projection of the skylights on the tea warehouse body is located between the second air inlet and the second air outlet.
[0015] Preferably, it also includes storage racks and lighting strips, and the lighting strips are laid on the ground between adjacent storage racks.
[0016] Preferably, the distance between adjacent racks is ≥60 cm, and the highest height of the rack is less than or equal to 2 / 3 of the height of the storage chamber.
[0017] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:
[0018] 1. On the one hand, the utility model sets a surrounding outer wall on the outside of the tea warehouse body to form an isolation passage, forming a certain temperature difference inside and outside the storage room, which can provide Pu'er tea with a more stable environment that adapts to the changes of the four seasons in combination with the regional climate, and meets the aging requirements of Pu'er tea; on the other hand, the wind direction is taken into consideration and the north wind is used as the control. The humidity of the north wind is relatively low, which is generally suitable for the temperature and humidity control requirements of the fermentation room.
[0019] 2. There are 4 storage rooms distributed in a cross shape, so as to build a complete year storage room and store new tea and old tea separately.
[0020] 3. A spoiler for separation is provided between the second air inlet and the second air outlet in each storage chamber, so that although the second air inlet and the second air outlet are located on the same side due to the existence of the isolation channel, a diagonal flow channel is formed, so that the air is mixed more evenly in the tea warehouse during ventilation.
[0021] 4. The utility model sets the lighting windows on the east and west sides of the outer wall, and avoids the second air inlet and the second air outlet, so as to prevent light from directly entering the storage room and destroying the conditional aroma and taste of the tea, but can provide a certain amount of light for the bacterial flora in time to promote aging.
[0022] 5. The lighting strip of the utility model is laid on the ground. When lighting is needed, light is shone upward from the ground, thereby reducing the adverse effects of direct sunlight on Pu'er tea. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example
[0036] Please refer to Figure 1 As shown, this embodiment provides a Pu'er fermentation room, which includes a tea warehouse body 100 and an outer wall 200, wherein the outer wall 200 is arranged around the tea warehouse body 100 to form an isolation channel 210, the width of the isolation channel 210 is 1.5m-3m, and the isolation channel 210 and the tea warehouse body 100 form a U-shaped structure as a whole.
[0037] A first air outlet 212 is provided on the south side of the outer wall 200, and a first fan 213 is provided on the first air outlet 212. When the first fan 213 is working, the air flow on the isolation channel 210 flows through the exhaust effect of the first fan 213; a first air inlet 211 is provided on the north side of the outer wall 200, so that fresh air is introduced from the outside when the first air inlet 211 is opened. A first filter 214 is provided on the first air inlet 211 to filter the introduced fresh air.
[0038] The tea storage body 100 includes a plurality of storage chambers 110, each of which is provided with a second air inlet 111 and a second air outlet 112 corresponding to the isolation passage 210 on the east / west side, that is, the second air inlet 111 and the second air outlet 112 are provided on the east or west side in the direction of the isolation passage 210, and the second air outlet 112 is provided with a second fan 113 for exhausting air from the storage chamber 110 to the isolation passage 210. In this way, when the first air inlet 211 is opened, the first air outlet 212 is opened, and the first fan 213 is working, fresh air will be introduced into the isolation passage 210; please refer to Figure 2 As shown, when the second air inlet 111 of a storage room 110 is opened, the second air outlet 112 is opened, and the second fan 113 is working, ventilation is performed with the isolation channel 210 .
[0039] In this embodiment, the first air inlet 211, the first air outlet 212, and the second air outlet 112 use ventilation windows 114; the second air inlet 111 uses an electric-controlled door, and the ventilation windows 114 and the electric-controlled door are opened when ventilation is required and closed at other times.
[0040] On the one hand, this embodiment sets a surrounding outer wall 200 on the outside of the tea warehouse body 100 to form an isolation channel 210, so as to form a certain temperature difference inside and outside the storage room 110. In this way, it can combine the regional climate to provide Pu'er tea with a more stable environment that conforms to the alternation of day and night and the change of seasons, which meets the aging requirements of Pu'er tea; in other words, the isolation channel 210 can suppress the influence of external temperature and humidity changes on the temperature and humidity in the storage room 110, so that the temperature and humidity fluctuations in the storage room 110 are small, and excessive temperature or humidity differences are avoided from destroying the fermentation environment of the tea species and affecting the quality of the tea. On the other hand, this embodiment takes into account the wind direction and adopts the north wind as the control. The north wind has relatively low humidity and is generally suitable for the temperature and humidity control requirements of the fermentation room.
[0041] Along the airflow direction generated by the first air inlet 211 and the second air outlet 112 , the second air inlet 111 of each storage chamber 110 is located on the north side of the second air outlet 112 to improve ventilation efficiency.
[0042] In this way, the temperature and humidity of each storage chamber 110 are usually smoothed through the isolation channel 210, and during regular ventilation or special circumstances (such as when the temperature is too high in summer), please refer to Figure 2 As shown in the storage chamber 110 in the upper left corner, the isolation channel 210 is opened and the second air inlet 111 and the second air outlet 112 of the corresponding storage chamber 110 are regulated.
[0043] In each storage chamber 110, the second air inlet 111 and the second air outlet 112 are located on the same side so as to exchange air with the isolation channel 210. In order to make each storage chamber 110 ventilated evenly, a spoiler 120 for separation is provided between the second air inlet 111 and the second air outlet 112, so that the second air inlet 111 and the second air outlet 112 are located on the same side due to the existence of the isolation channel 210, but form a diagonal flow channel, so that during ventilation, the air is mixed more evenly in the tea warehouse.
[0044] In a preferred embodiment, the wall of the second air outlet 112 is concave relative to the storage chamber 110 to form a concave wall 220 , so as to reduce the flow isolation effect of the airflow exhausted by the second fan 113 on the isolation channel 210 .
[0045] In a preferred embodiment, the second fan 113 is installed on the outside of the inner concave wall, and the first fan 213 is installed on the inside of the isolation channel 210, so as to facilitate cleaning and maintenance of the fans.
[0046] In the present embodiment, four storage chambers 110 are arranged in a cross-shaped distribution. Thus, the storage year of each storage chamber 110 can be defined in a clockwise / counterclockwise direction so that the age of the stored Pu'er tea decreases / increases, namely, the first storage chamber 110, the second storage chamber 110, the third storage chamber 110 and the fourth storage chamber 110.
[0047] In one example, the first storage chamber 110 is used to store newly-stored tea, with a storage period of generally 1-2 years, to remove unfavorable odors through natural purification; the second storage chamber 110 is used for the initial aging of the tea, with a storage period of generally 6-8 months, so that the moisture, enzymes and phenolic substances in the tea begin to change, and the bitterness of the tea gradually decreases; the third storage chamber 110 is used for the intermediate aging of the tea, with a period of generally 2-6 years, so that the catechins, tea polyphenols and other components in the tea begin to decompose, further reducing the bitterness of the tea; the fourth storage chamber 110 is used for the old aging of the tea, with a period of generally 2-6 years, so that the various components in the tea tend to stabilize, and finally the tea is shipped out for sale.
[0048] During the aging process of Pu'er tea, new tea is mixed with old tea to facilitate the inoculation of beneficial microorganisms, and the fermentation atmosphere of the old tea is used to increase the aging speed of the new tea. In order to prevent the old tea from being tainted by the new taste, a small amount of old tea is usually mixed with the new tea. However, a new problem arises, that is, when the tea leaves in each storage chamber 110 reach the end of the storage month or year, they are regularly transported to the storage chamber 110 of the next storage month or year for storage, which is time-consuming and labor-intensive, and the risk of external contaminants affecting the quality of the tea leaves is increased during the multiple manual transportation processes.
[0049] To this end, four cross-distributed ventilation windows 114 are provided at the cross-joint portions of the four storage chambers 110 , so that when they are opened separately, the adjacent storage chambers 110 can be connected separately.
[0050] If so, please refer to Figure 3 As shown, from the storage chamber 110 in the lower right corner along the clockwise direction, there are the first storage chamber, the second storage chamber, the third storage chamber and the fourth storage chamber. In the aforementioned example, since the first storage chamber and the second storage chamber are for tea of a younger age, the ventilation windows 114 between the fourth storage chamber and the first storage chamber, between the first storage chamber and the second storage chamber, and between the second storage chamber and the third storage chamber are not opened to prevent the old tea in the fourth storage chamber from being affected by the new tea; and the ventilation windows between the third storage chamber and the fourth storage chamber are opened periodically, for example, once every 10 days, for 1 day each time, to promote the alternation of raw and cooked teas while avoiding long-term mixing that affects the quality of the old tea.
[0051] It is easy to understand that when the first storage chamber and the second storage chamber are ventilated, the third storage chamber and the fourth storage chamber should not be opened.
[0052] When the new tea stored in the first storage room reaches the set month, the first storage room is regulated according to the initial aging regulation requirements of the second storage room. At this time, the first storage room actually becomes the second storage room; similarly, after the set period of each storage room 110 is reached, it becomes the storage room of the next period. After the set period of the fourth storage room is reached, it is transferred to the sales warehouse for sale. At this time, the fourth storage room becomes the first storage room for new tea.
[0053] In a preferred embodiment, enclosed skylights 115 are provided on the east and west sides of the outer wall 200. The skylights 115 use electric curtains to avoid light or let in light. The projection of the skylights 115 on the tea warehouse body 100 is located between the second air inlet 111 and the air outlet, so as to prevent light from directly entering the storage room 110 and destroying the conditioned aroma and taste of the tea leaves, but can provide a certain amount of light requirements for the bacterial flora in a timely manner to promote aging.
[0054] Please refer to Figure 4 As shown, in a preferred embodiment, the utility model further comprises a rack 300 and a lighting lamp 400, and the lighting lamp 400 is laid on the ground between adjacent racks 300. In this embodiment, the lighting lamp 400 is laid on the ground, and when lighting is needed, light is shone upward from the ground to reduce the adverse effects of direct light on the Pu'er tea.
[0055] The distance between adjacent racks 300 is ≥ 60 cm, and the highest height of the rack 300 is less than or equal to 2 / 3 of the storage chamber 110, so as to facilitate the uniform exchange of the tea atmosphere.
[0056] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
