With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention.

[0027] In the description of the present invention, terms such as "up", "down", "left", "right", "front", "back", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0028] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figures 1 to 5 As shown, the present embodiment provides a normal temperature non-destructive tea dehydration device, comprising a main cabinet 1 and a drying cabinet 2; the main cabinet 1 has a storage cavity 101 and an air inlet 12 and an air outlet 13 connected to the storage cavity 101, and the storage cavity 101 is used to store tea leaves. Of course, the main cabinet 1 is also provided with a double-opening cabinet door 11, and operations such as taking and placing tea leaves are realized by opening or closing the cabinet door 11. The air inlet 12 and the air outlet 13 are respectively arranged on the upper side and the lower side of the main cabinet 10.

[0030] Specifically, the drying cabinet 2 is fixed on the right side of the main cabinet 1. The drying cabinet 2 is provided with a first opening 21 connected to the air inlet 12 of the main cabinet 1 and a second opening 22 connected to the air outlet 13 of the main cabinet 1; so that a circulating air path is formed between the drying cabinet 2 and the main cabinet 1, and an air circulation machine 20 for driving the circulation of air is connected to the circulating air path; specifically, in this embodiment, the air circulation machine 20 is arranged between the air outlet 13 of the main cabinet 1 and the second opening 22 of the drying cabinet 2, and of course, it can also be arranged between the air inlet 12 of the main cabinet 1 and the first opening 21 of the drying cabinet 2. The first opening 21 of the drying cabinet 2 is provided with a first filter membrane 23 for blocking water molecules.

[0031] An electronic scale 41 is provided in the drying cabinet 2 . The electronic scale 41 is used to store the water absorbent. The electronic scale 41 weighs the water absorbent and outputs the weight to be connected to a controller 42 . The controller 42 is connected to the air circulation machine 20 and an alarm 43 .

[0032] The working principle is as follows: the tea leaves with high moisture content that need to be dehydrated are stored in the storage chamber 101 of the main cabinet 1; the air circulation machine 20 is started, and the air in the storage chamber 101 is driven to flow out from the air outlet 13, and flow into the drying cabinet 2 through the second opening 22, and after being processed by the drying cabinet, the air flows through the first opening 21 to the air inlet 12 of the main cabinet 1, and flows back into the storage chamber 101 from the air inlet 12 to realize internal circulation; during the process, when the air flows through the drying cabinet 2, the water absorbent stored on the electronic scale 41 in the drying cabinet 2 will absorb the water molecules in the air; at the same time, the water molecules in the air flowing in from the air inlet 12 of the main cabinet 1 will also be blocked by the first filter membrane 23, so that the water molecules in the air remain in the drying cabinet 2. As the water absorbent continuously absorbs water molecules in the circulating air, its weight will continue to increase. The electronic scale 41 monitors the weight of the water absorbent in real time and outputs it to the controller 42. The controller 42 can use a microcomputer system in the prior art. Once the water absorbent absorbs the preset amount of water, it can provide timely feedback (through the alarm 43) and stop the air circulation machine 20, which is convenient for timely processing. It allows high-water content tea to be efficiently processed at room temperature, maintaining its original flavor, essence and nutrients; and can accurately control the moisture content of the tea, achieving higher quality tea drying and lossless processing.

[0033] The electronic scale 41 weighs the water absorbent and outputs the result to the controller 42, so as to accurately obtain the water absorption amount and thus accurately obtain the water removal rate of the tea leaves (water removal rate = water absorption amount / total weight of the tea leaves when put in); thus, the moisture content of the tea leaves can be accurately controlled.

[0034] Specifically, the first filter membrane 23 is a polymer membrane or an inorganic membrane with a pore size of 0.1 nanometers to 0.25 nanometers; specifically, it is a hydrophobic PTFE (polytetrafluoroethylene) filter membrane. The first filter membrane 23 with a pore size of 0.1 nanometers to 0.25 nanometers allows air to pass through while blocking water molecules from passing through, and can achieve isolation of water molecules from air. Of course, in other embodiments, the first filter membrane 23 can also be other polymer membranes, such as a hydrophobic PVA (polyvinyl alcohol) filter membrane, etc.; it can also be an inorganic membrane, etc.; the pore size range is not limited to 0.1 nanometers to 0.25 nanometers, as long as it can allow air to pass through while blocking water molecules from passing through.

[0035] Furthermore, the air outlet 13 of the main cabinet 10 is provided with a second filter membrane 32 for passing water molecules and blocking aromatic hydrocarbon molecules. The second filter membrane 32 can extract water molecules in the storage cavity 101 from the air outlet 13 and retain aromatic hydrocarbon molecules in the air, thereby better retaining the natural flavor and nutritional components of the tea.

[0036] Specifically, the second filter membrane 32 is a polymer membrane or an inorganic membrane with a pore size of 0.3 nanometers to 0.5 nanometers, which can well ensure the passage of water molecules and block aromatic hydrocarbon molecules. The second filter membrane 32 can be a polymer membrane such as a PVA (polyvinyl alcohol) membrane or a PTFE (polytetrafluoroethylene) membrane; it can also be an inorganic membrane; the pore size range is not limited to 0.3 nanometers to 0.5 nanometers, as long as it can allow water molecules to pass through and block aromatic hydrocarbon molecules.

[0037] Furthermore, during the storage of tea leaves, some of the tea hairs on the tea leaves will separate from the tea leaves themselves and float in the air. Therefore, in this embodiment, the air inlet 12 of the main cabinet 1 is provided with a first non-woven membrane 31, and the air outlet 13 of the main cabinet 1 is provided with a second non-woven membrane 33; the provision of the first non-woven membrane 31 and the second non-woven membrane 33 can effectively block the tea hairs in the air. Specifically, the second filter membrane 32 and the second non-woven membrane 33 are stacked. For example, in this embodiment, the second non-woven membrane 33 is located on the upper layer of the second filter membrane 32. When the air in the storage chamber 101 is drawn out from the air outlet 13, the second non-woven membrane 33 located on the upper layer will first block the large particles such as tea hairs in the air, and effectively protect the second filter membrane 32. Specifically, the first non-woven membrane 31 is provided at the air inlet 12 to block the large particles such as tea hairs, and prevent the reverse entry from the air inlet 12 to contaminate the first filter membrane 31. Of course, in other embodiments, the first non-woven membrane 31 may be provided at the air inlet 12 of the main cabinet 1 alone, or the second non-woven membrane 33 may be provided at the air outlet 13 of the main cabinet 1 alone.

[0038] Specifically, the alarm 43 is a buzzer or an audible and visual alarm, which can intuitively provide feedback to the operator. Of course, in other embodiments, the alarm 43 can also use methods such as sending text messages to remind the operator.

[0039] The water absorbing agent stored on the electronic scale 41 is calcium oxide, which has a strong water absorbing capacity, and the calcium hydroxide generated after absorbing water is easy to handle. Of course, in other embodiments, other water absorbing agents that are easy to absorb water can also be used. Specifically, the electronic scale 41 is provided with a carrier plate 411, and the carrier plate 411 is used to place the water absorbing agent. The controller 42 is sealed and embedded in the cabinet door 24 of the drying cabinet 2, so that the internal and external wiring of the drying cabinet 2 is reduced.

[0040] At least one group of slots 14 is provided on the side wall of the storage cavity 101, and specifically, multiple groups of slots 14 are provided from bottom to top, each group of slots 14 is used to insert a tray 15, and the accompanying drawings only illustrate that a tray 15 is inserted in one group of slots 14, specifically, the tray 15 is used to store tea leaves and has mesh holes for air circulation.

[0041] Preferably, the air circulation machine 20 is an air compressor, which can compress air so that the output air has a strong pressure, ensuring that the air flows into the storage chamber 101 from the first filter membrane 23 of the air inlet 12. Of course, in other embodiments, other devices such as circulating fans that can drive air circulation can also be used.

[0042] The above solution provided by this embodiment has the following advantages:

[0043] 1. Normal temperature processing: avoid high temperature damage to the quality of tea and retain the natural flavor and nutrients of tea.

[0044] 2. High-efficiency separation: The first filter membrane 23 is combined with a water-absorbing agent (calcium oxide in this embodiment) to absorb water, thereby ensuring that the air is dry and improving the drying efficiency.

[0045] 3. Rapid reaction: Calcium oxide has strong water absorption capacity, and the product calcium hydroxide is easy to handle.

[0046] 4. Precise control: Real-time monitoring by the controller 42 and the electronic scale 41 can precisely control the amount of water removed according to the needs of different tea leaves.

[0047] 5. Environmental protection and energy saving: no additional heating energy is required, saving energy costs, the product is easy to handle, and it is environmentally friendly.

[0048] 6. Through the setting of the controller 42 and the electronic scale 41, the degree of automation is high.

[0049] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
