[0007] In some embodiments, when the evaluation parameter does not fall within a preset range, adjusting the temperature inside the container so that the evaluation parameter is within the preset range includes: when the evaluation parameter is greater than an upper limit of the preset range, lowering the temperature inside the container; and when the evaluation parameter is less than a lower limit of the preset range, increasing the temperature inside the container.

[0008] In some embodiments, the evaluation parameter is the sum of the first term and the second term.

[0009] In some embodiments, the first item is the temperature within the container.

[0010] In some embodiments, n is 3.

[0019] In the disclosed embodiment, when the moisture content of the tobacco leaves is low and the humidity of the environment in which the rehumidifier is located is low, the frequency of applying steam to the container in which the tobacco leaves are placed in the rehumidifier and the temperature in the container are increased to ensure that the moisture content of the tobacco leaves is within the desired moisture content range. This eliminates the need to perform heating and humidification operations in all cases, thereby helping to reduce energy consumption.

[0025] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0026] The relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.

[0027] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not necessarily drawn according to the actual proportional relationship.

[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0029] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0030] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0031] In addition, in the description of the present disclosure, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance and order. Similarly, although operations are depicted in a particular order in the accompanying drawings, this should not be understood as requiring that such operations be performed in the particular order shown or in a sequential order, or requiring that all illustrated operations be performed to achieve the desired results. In some cases, multitasking and parallel processing can be advantageous.

[0032] Figure 1 It is a flow chart of a method for controlling tobacco leaf moisture regain according to some embodiments of the present disclosure.

[0033] In step 102, the moisture content of the tobacco leaves at the outlet of the moisture conditioning machine is obtained.

[0034] As some embodiments, a moisture meter is provided at the discharge port of the rehumidifier, and the moisture meter can measure the moisture content of the tobacco leaves at the discharge port. In this case, the moisture content of the tobacco leaves can be obtained from the moisture meter.

[0035] In step 104, the humidity of the environment in which the rehumidifying machine is located is obtained.

[0036] As some embodiments, a hygrometer is provided in the plant where the rehumidifier is placed, and the hygrometer can measure the humidity of the environment where the rehumidifier is located. In this case, the moisture content of the tobacco leaves can be obtained from the hygrometer.

[0037] As other implementation methods, the ambient humidity in the meteorological data can be used as the humidity of the environment where the dehumidification machine is located. In this way, there is no need to install a hygrometer in the factory, which helps to reduce costs.

[0038] For example, the meteorological data is the meteorological data of the administrative area where the factory building where the moisture reconditioning machine is located is located. The administrative area may be a prefecture-level administrative area, a county-level administrative area, or a township-level administrative area. For another example, the meteorological data may be obtained from the Internet.

[0039] In step 106, when the moisture content of the tobacco leaves is less than the first preset moisture content and the humidity of the environment in which the rehumidifier is located is less than the preset humidity, the frequency of applying steam to the container in which the tobacco leaves are placed in the rehumidifier and the temperature in the container are increased so that the moisture content of the tobacco leaves is greater than or equal to the first preset moisture content and less than or equal to the second preset moisture content.

[0040] As some embodiments, the frequency of applying steam may range from 20 Hz to 25 Hz. For example, the frequency of applying steam may range from 20 Hz, 21 Hz, 22 Hz, 23 Hz, 24 Hz or 25 Hz.

[0041] It should be understood that the frequency of applying steam may also be a non-integer value, which is not limited here.

[0042] As some embodiments, the temperature in the container where the tobacco leaves are placed in the rehumidifier can be increased by delivering hot air to the container.

[0043] As other embodiments, the container in which the tobacco leaves are placed in the rehumidifier can be directly heated to increase the temperature in the container.

[0044] For example, a first container for placing tobacco leaves in a rehumidifier is placed in a second container, and an interlayer is provided between the outer wall of the first container and the inner wall of the second container, and a heat medium is provided in the interlayer. The temperature in the first container for placing tobacco leaves can be increased by increasing the temperature of the heat medium in the interlayer. The heat medium includes, for example, steam.

[0045] As some embodiments, the container for placing tobacco leaves in the rehumidifying machine can be a cylinder.

[0046] As some implementation modes, the preset humidity may be in the range of 50% to 70%. For example, the preset humidity may be in the range of 50%, 55%, 60%, 65% or 70%.

[0047] It should be understood that the first preset moisture content and the second preset moisture content can be set according to process requirements, and the value range of the preset humidity can also be set according to actual conditions.

[0048] In the above embodiment, when determining how to adjust the frequency of applying steam to the container in which tobacco leaves are placed in the rehumidifier and the temperature in the container, not only the moisture content of the tobacco leaves but also the humidity of the environment in which the rehumidifier is located are considered. When the moisture content of the tobacco leaves is low and the humidity of the environment in which the rehumidifier is located is low, the frequency of applying steam to the container in which tobacco leaves are placed in the rehumidifier and the temperature in the container are increased. In this way, there is no need to perform heating and humidification operations in all cases, which helps to reduce energy consumption.

[0049] In some embodiments, when the moisture content of the tobacco leaves is less than a first preset moisture content and the humidity of the environment in which the rehumidifier is located is greater than or equal to the preset humidity, only the temperature inside the container is increased so that the moisture content of the tobacco leaves is greater than or equal to the first preset moisture content and less than or equal to the second preset moisture content.

[0050] In this way, when the humidity of the environment in which the rehumidifier is located is high, only the temperature of the container in which the tobacco leaves are placed in the rehumidifier is increased, without adjusting the frequency of applying steam to the container in which the tobacco leaves are placed. The humidity of the environment in which the rehumidifier is located can be used to rehumidify the tobacco leaves, thereby further reducing energy consumption when the moisture content of the tobacco leaves meets the expectations.

[0051] In some embodiments, after increasing the frequency of applying steam to the container in which the tobacco leaves are placed in the rehumidifier and the temperature in the container, the evaluation parameters of the tobacco leaves can be determined based on the temperature in the container and the humidity of the environment in which the rehumidifier is located.

[0052] Here, the evaluation parameter includes a first item and a second item, the evaluation parameter is positively correlated with the first item, and the evaluation parameter is positively correlated with the second item. The first item of the evaluation parameter is positively correlated with the temperature in the container where the tobacco leaves are placed in the rehumidifier, and the second item of the evaluation parameter satisfies an n-order function relationship with the humidity of the environment where the rehumidifier is located, and n is greater than or equal to 2.

[0053] Depending on whether the evaluation parameters of the tobacco leaves fall within the preset range, it can be determined whether the tobacco leaves meet the expected evaluation indicators.

[0054] If the evaluation parameter of the tobacco leaves does not fall within the preset range, the temperature of the container in which the tobacco leaves are placed in the rehumidifier is adjusted so that the evaluation parameter of the tobacco leaves falls within the preset range. If the evaluation parameter of the tobacco leaves falls within the preset range, the temperature of the container in which the tobacco leaves are placed in the rehumidifier is maintained.

[0055] In some embodiments, the preset range is related to the evaluation index of the desired tobacco leaf. For example, the preset range is related to the desired taste of the tobacco leaf, and the lower limit of the preset range when the desired taste of the tobacco leaf is mellow is higher than the lower limit of the preset range when the desired taste of the tobacco leaf is fresh. In other words, when the evaluation parameter of the tobacco leaf falls within the preset range, the tobacco leaf meets the desired evaluation index.

[0056] It should be understood that the upper limit and the lower limit of the preset range can be set according to actual needs.

[0057] In the above embodiment, the temperature in the container is adjusted according to the preset range and the evaluation parameters of the tobacco leaves, so that the evaluation parameters of the tobacco leaves are within the preset range, which helps to improve the stability of the quality of the tobacco leaves during the processing.

[0058] In some embodiments, when the evaluation parameter of the tobacco leaves is greater than the upper limit of a preset range, the temperature inside the container in which the tobacco leaves are placed in the rehumidifier is lowered; and when the evaluation parameter of the tobacco leaves is less than the lower limit of the preset range, the temperature inside the container in which the tobacco leaves are placed in the rehumidifier is increased.

[0059] In the above embodiments, in response to various situations when the evaluation parameters of the tobacco leaves do not fall within the preset range, the temperature in the container in which the tobacco leaves are placed in the rehumidifier is increased or decreased, so that the evaluation parameters of the tobacco leaves can be within the preset range, which helps to improve the stability of the quality of the tobacco leaves during the processing.

[0060] Through research, it was found that by adjusting the relationship between the evaluation parameters of tobacco leaves and the first item and the second item, the relationship between the first item and the temperature in the container where the tobacco leaves are placed in the rehumidifier, and the relationship between the second item and the humidity of the environment in which the rehumidifier is located, the evaluation parameters of tobacco leaves can more accurately reflect the quality of tobacco leaves.

[0061] In some embodiments, based on the desired quality of tobacco leaves, the relationship between the evaluation parameters of the tobacco leaves and the temperature in the container where the tobacco leaves are placed in the rehumidifier and the humidity of the environment in which the rehumidifier is located can be determined by a machine learning model.

[0062] Next, some embodiments are introduced in which the evaluation parameters of tobacco leaves can more accurately reflect the quality of tobacco leaves.

[0063] In some embodiments, the evaluation parameter of the tobacco leaf is the sum of the first item and the second item.

[0064] In some embodiments, the first item is the temperature inside the container where the tobacco leaves are placed in the conditioning machine.

[0065] In some embodiments, n is 3. That is, the second item of the evaluation parameter of the tobacco leaf satisfies a cubic function relationship with the humidity of the environment in which the conditioning machine is located.

[0066] In some embodiments, the evaluation parameter of the tobacco leaf is calculated by the following formula: P=T+a*x 3 -b*x 2 +c*xd.

[0067] Here, P is an evaluation parameter of tobacco leaves, T is the temperature in the container where the tobacco leaves are placed in the rehumidifier, x is the humidity of the environment in which the rehumidifier is located, and a, b, c and d are constants greater than 1.

[0068] In the above embodiment, using a cubic polynomial to calculate the evaluation parameters of tobacco leaves can better capture the nonlinear changes in the impact of the humidity of the environment in which the rehumidification machine is located on the evaluation parameters of tobacco leaves. The evaluation parameters of tobacco leaves can more accurately reflect the quality of tobacco leaves, so as to further improve the accuracy of the control of tobacco leaf rehumidification.

[0069] Through research, it is found that the value ranges of a, b, c and d will affect the accuracy of tobacco leaf evaluation parameters in reflecting tobacco leaf quality. By adjusting the values ​​of a, b, c and d, the embodiment of the present disclosure proposes a value range for a, b, c and d that enables tobacco leaf evaluation parameters to more accurately reflect tobacco leaf quality.

[0070] In some embodiments, the value range of a is 32 to 34, the value range of b is 82 to 84, the value range of c is 89 to 90, and the value range of d is 39 to 40.

[0071] For example, a is 32, 33 or 34; for another example, b is 82, 83 or 84; for another example, c is 89 or 90; for another example, d is 39 or 40.

[0072] It should be understood that a, b, c and d are not limited to integers and may also be non-integers, which is not limited here.

[0073] Each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments.
