Description

[0002] White tea, a kind of micro-fermented tea, is a special treasure among Chinese teas. During the aging process, white tea will undergo a series of changes such as microbial fermentation, oxidation reaction, texture change, aroma change and taste change. These changes make white tea have a unique taste and aroma, so there is a demand for the storage and aging of white tea, and white tea storage is produced.

[0003] Unlike other tea varieties such as white tea, white tea has its specificity, mainly in its strong hygroscopicity and oxidizability. The hygroscopicity of white tea causes it to absorb moisture as the humidity in the air increases, increasing the moisture content of white tea. If the humidity is not properly controlled, it will cause mold growth in white tea. At the same time, due to the effect of hygroscopicity, white tea is more sensitive to temperature. White tea with high water content will oxidize faster in a high-temperature storage environment.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0048] Example 1

[0049] Please refer to Figure 1 As shown, the present invention discloses a white tea storage chamber, which includes a tea chamber body 100, an outer wall 200, a hygrometer 160 and a controller (not shown in the figure).

[0050] Please refer to the following: Figure 2 As shown, the walls of the tea storage body 100 include a brick wall 130, a cedar wood board 140, and a flexible sealing element 150. The flexible sealing element 150 is used to seal the gaps between adjacent cedar wood boards 140 and the gaps between the cedar wood board 140 and the brick wall 130. The flexible sealing element 150 is preferably a W-shaped folded sealing element, which can not only achieve gap sealing, but also adapt to the expansion of the cedar wood board 140 after absorbing moisture.

[0051] For the cedar plank 140, considering the cost of the cedar plank thickness and improving moisture absorption, at least two layers of cedar planks 140 can be used to form a bonding structure with the brick wall 130, with a sandwich layer formed between the layers of cedar planks 140, and a hygrometer 160 installed in the sandwich layer. The flexible sealing elements 150 of each layer of cedar planks 140 in the sandwich layer are staggered. The hygrometer 160 is embedded in the cedar plank 140 or the sandwich layer of cedar planks 140 to detect the humidity of the cedar plank 140.

[0052] Please refer to Figure 1 As shown, the outer wall 200 is arranged around the tea storage body 100 to form a ring-shaped isolation channel 210. A dehumidification device 400 is provided in the isolation channel 210 to control the humidity in the isolation channel 210.

[0053] The controller acquires the humidity value from the hygrometer 160. When the detected value of the hygrometer 160 is greater than the preset value, it controls the dehumidification device 400 to work.

[0054] Thus, on the one hand, the isolation channel 210 can create a certain humidity and temperature difference between the inside and outside of the storage room 110, which, combined with the regional climate, provides white tea with a more stable environment that adapts to the changing seasons, reducing the impact of external humidity or temperature changes on the environment inside the tea storage unit 100. On the other hand, the degreasing treatment of the cedar wood further improves its hygroscopicity, using the cedar wood to absorb excess moisture in the tea storage unit 100, preventing excessive humidity in the tea storage unit 100 from causing mold growth in the white tea, thereby utilizing the physical properties of the material to reduce the energy consumption of the tea storage unit 100. When the humidity of the cedar wood itself is too high, the dehumidification device 400 in the isolation channel 210 is activated to reduce the humidity of the cedar wood. In this way, by using the cedar wood as an intermediate carrier of moisture, moisture is absorbed and dehumidified indirectly, avoiding direct dehumidification in the tea storage unit 100 and thus preventing damage to the storage atmosphere.

[0055] The cedar board 140 in this embodiment is made by the following method: S1, the cedar wood is cut into cedar board 140 with a thickness of 15-20mm, and placed in... Soaking in calcium carbonate solution at a water temperature of Soak for 15-20 days, utilizing the alkalinity of calcium carbonate to react with the oils, saponifying the oils and causing them to precipitate; S2, place the soaked cedar boards (140) into a drying oven for baking, first at 40-50℃ for 1.5-2 hours to allow the cedar boards (140) to adapt to the temperature and prevent cracking, then raise the temperature to... negative pressure bake Using temperature and negative pressure, the oil is further extracted; S3, 2-3mm of wood thickness is planed off from both sides of the cedar board 140 to prevent the extracted oil from accumulating on both sides of the board and clogging the pores; S4, the cedar board 140 is first soaked in a chlorine dioxide solution, the water temperature... Soaking time To eliminate pests and bring the pH of the cedar wood boards to near neutral, they were finally soaked in deionized water. S5. After air drying, remove and set aside.

[0056] Sample plates 1-3 were prepared using the method described above.

[0057] Sample 1: S1. Cut the fir wood into 15mm thick fir boards 140, soak them in a 5.5% calcium carbonate solution at 60℃ for 15 days; S2. Place the soaked fir boards 140 in a drying room for baking. First, bake at 40℃ for 1.5-2 hours to allow the fir boards 140 to adapt to the temperature and prevent cracking, then raise the temperature to 100℃ and bake at a negative pressure of 0.05Mpa for 2 hours; S3. Plane off 2mm of wood thickness from both sides of the fir boards 140; S4. First soak the fir boards 140 in a chlorine dioxide solution at 60℃ for 5 hours, then soak them in deionized water for 10 hours; S5. Remove them after air drying for later use.

[0058] Sample 2: S1. Cut the fir wood into fir boards 140 with a thickness of 18mm, soak them in a 5.5% calcium carbonate solution at 70℃ for 18 days; S2. Place the soaked fir boards 140 in a drying room for baking. First, bake at 45℃ for 2 hours to allow the fir boards 140 to adapt to the temperature and prevent cracking, then raise the temperature to 105℃ and bake under a negative pressure of 0.1Mpa for 2.5 hours; S3. Plane off 2mm of wood thickness from each side of the fir boards 140; S4. First soak the fir boards 140 in a chlorine dioxide solution at 60℃ for 6 hours, and finally soak them in deionized water for 13 hours; S5. Remove them after air drying for later use.

[0059] Sample 3: S1. Cut the fir wood into 20mm thick fir boards 140, soak them in a 6% calcium carbonate solution at 75℃ for 20 days; S2. Place the soaked fir boards 140 in a drying room for baking. First, bake at 45℃ for 2 hours to allow the fir boards 140 to adapt to the temperature and prevent cracking, then raise the temperature to 105℃ and bake under a negative pressure of 0.1Mpa for 3 hours; S3. Plane off 3mm of wood thickness from each side of the fir boards 140; S4. First soak the fir boards 140 in a chlorine dioxide solution at 70℃ for 8 hours, then soak them in deionized water for 15 hours; S5. Remove them after air drying for later use.

[0060] Comparative plates 1-3 were prepared. The comparative plates were not degreased and were allowed to air dry naturally. The plate thicknesses were 15 mm, 18 mm and 20 mm, respectively.

[0061] Both the sample plate and the control plate were cut into 90mm*90mm sizes for permeability testing:

[0062] Weigh and record the test specimen, then place it in a vacuum chamber and evacuate for 1 hour at a vacuum level of 0.01 MPa. After the vacuum is completed, introduce the prepared concentration (0.3%) of acid red dye, continue evacuating for 0.5 hours, and then remove the test specimen and dye.

[0063] After dyeing, the test specimens were placed in a pressure vessel and sealed. The air compressor was started and pressurized to 0.8 MPa and then stopped. After maintaining the pressure for 5 hours, the test specimens were removed, the surface moisture was wiped off, and the weight was recorded.

[0064] Place the specimen at room temperature until the wood is air-dried. Then, cut the specimen at different locations along the longitudinal and transverse grain of the wood to observe the longitudinal and transverse penetration depths, and measure and record them.

[0065] The data is as follows:

[0066]

[0067] The cedar wood board 140 of the present invention, after degreasing treatment, exhibits significantly improved permeability and hygroscopicity compared to conventional wood boards. Therefore, the cedar wood board 140 of the present invention can promote humidity regulation of the tea storage unit 100.

[0068] In a preferred embodiment, a first air inlet 211 is configured on the north side of the outer wall 200, and a first air outlet 212 is configured on the south side of the outer wall 200. A first fan 213 is installed on the first air outlet 212. In this way, when ventilating the isolation channel 210, the wind direction is taken into consideration, and the north wind is used for regulation. The humidity of the north wind is relatively low, which is generally suitable for the temperature and humidity control requirements of the tea warehouse.

[0069] In a more preferred embodiment, the tea storage body 100 includes several storage chambers 110. Each storage chamber 110 has a second air inlet 111 and a second air outlet 112 on its east / west side, corresponding to the isolation channel 210. A second fan 113 is installed on the second air outlet 112. The second air inlet 111 of each storage chamber 110 is located to the north of the second air outlet 112 to improve ventilation efficiency.

[0070] In this way, the humidity and temperature of each storage room 110 are normally balanced through the isolation channel 210. However, during regular ventilation or in special circumstances (such as when the temperature is too high in summer), please refer to... Figure 3 As shown in the upper left corner of the storage room 110, the isolation channel 210 and the second air inlet 111 and the second air outlet 112 of the corresponding storage room 110 are opened for regulation.

[0071] In each storage chamber 110, the second air inlet and the second air outlet 112 are located on the same side to facilitate air exchange with the isolation channel 210. To ensure uniform air exchange in each storage chamber 110, a baffle 120 is provided between the second air inlet 111 and the second air outlet 112 for separation. Although the second air inlet 111 and the second air outlet 112 are located on the same side due to the presence of the isolation channel 210, they form a diagonal flow channel, which makes the air mix more evenly in the tea storage chamber during air exchange.

[0072] In a preferred embodiment, the wall of the second air outlet 112 is recessed relative to the storage chamber 110 to form a recessed wall 220, thereby reducing the impact of the airflow discharged from the second fan 113 on the isolation channel 210.

[0073] Furthermore, in a preferred embodiment, the permissible opening times for ventilation of the second air inlet 111 and the second air outlet 112 are 7-10 hours and 18-21 hours, respectively, to facilitate ventilation with the isolation channel 210 when the temperature is too high in summer, thereby reducing the need for air conditioning in the storage room 110. When the humidity in the storage room also fails to meet the requirements and exceeds a preset value, the permissible opening time for ventilation of the second air inlet 111 and the second air outlet 112 is 18-21 hours.

[0074] Example 2

[0075] The second aspect of the present invention provides a control method for white tea storage warehouses, which aims to control the humidity of the white tea storage warehouses described in Example 1 to achieve stable humidity in the tea storage warehouses.

[0076] Please refer to Figure 4 As shown, when the humidity value h of the hygrometer 160 obtained by the controller is greater than or equal to h1, the dehumidification device 400 is controlled to work, where h1 is the set humidity threshold.

[0077] Thus, the tea storage body 100 of the present invention is at least partially constructed from degreased cedar wood. The degreased cedar wood further improves its hygroscopicity, utilizing the hygroscopicity of the cedar wood to absorb excess moisture in the tea storage body 100, preventing excessive humidity in the tea storage body 100 from causing mold growth in the white tea. This utilizes the physical properties of the material to reduce the energy consumption of the tea storage body 100. At the same time, by using cedar wood as an intermediate moisture carrier, it indirectly absorbs and dehumidifies, avoiding direct dehumidification in the tea storage body 100 and thus preventing damage to the storage atmosphere.

[0078] In addition, due to its strong hygroscopicity and high moisture content, white tea is more sensitive to temperature. High storage temperatures accelerate the oxidation of white tea. Therefore, temperature monitoring is a key factor that needs to be controlled during the storage of white tea.

[0079] For details, please refer to Figure 1As shown, a plurality of temperature detection points are configured in the ring isolation channel 210, and a temperature sensor 300 is configured at each temperature detection point. An air conditioning duct and a plurality of circulating fans 500 are configured around the isolation channel 210. The air conditioning duct is configured with an independent air outlet corresponding to each temperature detection point (in a preferred embodiment, the air conditioning duct and the dehumidification device 400 share a duct). The independent air outlets can be controlled to open and close via electric valves; the electrification of the dampers is prior art and will not be described in detail here. Similarly, a plurality of circulating fans 500 are also arranged around the isolation channel 210, located at several points along the path of the air conditioning duct. A controller is used to collect the parameters collected by the temperature sensors 300 and to control the operation of the air conditioner, dampers, and circulating fans 500.

[0080] Please refer to Figure 3 As shown, the controller is configured to: set a first temperature threshold T1 and a second temperature threshold T2, collect the temperature Tp of each temperature detection point, calculate the average temperature Ta of the isolation channel 210210, and calculate ΔT=|Tp-Ta|; when a certain temperature detection point satisfies T1<ΔT≤T2, turn on the circulating fan 500 until ΔT≤T1; when a certain temperature detection point satisfies ΔT>T2, start the air conditioner and open the independent air outlet of the air conditioner duct corresponding to that temperature detection point until ΔT≤T1.

[0081] Thus, temperature detection is performed according to a set cycle (e.g., one hour): First, the average temperature Ta of the isolation channel 210 is calculated based on the temperature Tp of each temperature detection point. Using the average temperature Ta as a reference improves the robustness of the system. Second, when the temperature value at a certain temperature detection point is abnormal (too high or too low, usually due to localized overheating caused by sunlight), if the overtemperature value is less than the first threshold, simply turning on the circulating fan 500500 to circulate the isolation channel 210 achieves temperature balance. However, when a certain overtemperature point is too high, due to the heat storage and insulation effect of the wall, relying solely on the circulating fan 500 will take a long time to normalize the temperature of the local overtemperature point. Therefore, at this time, by turning on the air conditioner and its corresponding independent air outlet, cold air is introduced to lower the temperature below the first threshold, roughly offsetting the heat storage of the wall, and then the circulating fan 500 circulates the air to stabilize the temperature. In a feasible implementation, the first temperature threshold T1 can be configured to 3℃, and the second temperature threshold T2 can be configured to 5℃.

[0082] Please refer to Figure 6 As shown, in a more preferred embodiment, the controller also performs anomaly detection before calculating the average temperature Ta:

[0083] Obtain the orientation and sunlight model of the tea storage unit 100100. Match the sunlight model according to the orientation of the tea storage unit 100, and record the outdoor temperature value Tt1, light intensity Lt1, and temperature Tpt1 at each temperature detection point at historical time t1. Establish a mapping table with the outdoor temperature value Tt1 and the light intensity Lt1 at each temperature detection point as indexes, and the temperature Tpt1 interval at each temperature detection point as the result. It is easy to understand that when clustering the outdoor temperature value Tt1 and the light intensity Lt1 at each temperature detection point, a certain deviation is allowed; that is, the outdoor temperature value Tt1 and the light intensity Lt1 obtained by clustering are actually a range of values. Similarly, the corresponding temperature Tpt1 interval is also a range of values. Obtain values ​​for a certain period (e.g., one year) as basic data and continuously update this data thereafter.

[0084] Set the third temperature threshold T3 and the fourth temperature threshold T4;

[0085] Obtain the outdoor temperature value Tt at the current time t, the light intensity Lt at each temperature detection point, and query the corresponding Tpt1 interval;

[0086] The system checks whether the temperature Tpt of each temperature detection point at the current time t falls within the Tpt1 interval. If yes, the anomaly detection process terminates. If no, it calculates the deviation value ΔTpt, where ΔTpt = |Tpt - Tpt1|. When a temperature detection point satisfies T3 < ΔTpt ≤ T4, it outputs an anomaly alert for that temperature detection point. When a temperature detection point satisfies Tpt > T4, it checks whether other temperature detection points have Tpt falling within the Tpt1 interval. If no, it outputs a temperature anomaly alert; if yes, it outputs an anomaly alarm for that temperature detection point.

[0087] Thus, when the deviation between the actual collected temperature value and the historical value at a certain temperature detection point is within T3 and T4, an anomaly may occur, and an anomaly alert will be output to remind staff to investigate. Conversely, when the deviation between the actual collected temperature value and the historical value at a certain temperature detection point exceeds T4, but the temperatures at other temperature detection points all fall within the Tpt1 range, the sensor at that temperature detection point is determined to be faulty, and an anomaly alarm will be immediately output to urge staff to check and troubleshoot the problem. In one specific implementation, T3 is set to 3°C and T4 is set to 5°C.

[0088] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.

Set a third temperature threshold T3 and a fourth temperature threshold T4; Obtain the outdoor temperature value Tt at the current time t, the light intensity Lt at each temperature detection point, and query the corresponding Tpt1 interval; The system checks whether the temperature Tpt of each temperature detection point at the current time t falls within the Tpt1 interval. If yes, the anomaly detection process terminates. If no, it calculates the deviation value ΔTpt, where ΔTpt = |Tpt - Tpt1|. When a temperature detection point satisfies T3 < ΔTpt ≤ T4, it outputs an anomaly alert for that temperature detection point. When a temperature detection point satisfies Tpt > T4, it checks whether other temperature detection points have Tpt falling within the Tpt1 interval. If no, it outputs a temperature anomaly alert; if yes, it outputs an anomaly alarm for that temperature detection point.
