[0003] Artificial aging refers to controlling the aging process of redried tobacco strips by controlling conditions such as temperature, humidity, oxygen, and carbon dioxide to maintain the quality of the redried tobacco strips. Controlled atmosphere aging has become a more common artificial aging method in the storage and maintenance of redried tobacco strips.

[0004] During the controlled atmosphere aging process, relative humidity is one of the key conditions that affects the transformation of the internal components of tobacco leaves.

When the target equilibrium relative humidity range is met, the target atmosphere parameter adjustment value of the first target atmosphere parameter and / or the second target atmosphere parameter is determined according to the target equilibrium relative humidity range, and the preset target atmosphere parameter is automatically adjusted according to the target atmosphere parameter adjustment value, so that the first controlled atmosphere storage environment and the second controlled atmosphere storage environment meet the target equilibrium relative humidity range. Since the equilibrium relative humidity is taken as the starting point, the adjustment parameters are obtained by referring to the environment with re-roasted tobacco strips and the environment without re-roasted tobacco strips, and the relative humidity of the atmosphere controlled environment of the re-roasted tobacco strips is automatically regulated, so that the relative humidity of the re-roasted tobacco strips moves in a direction that is conducive to the aging of the tobacco strips, so that the adjusted relative humidity is more in line with the aging requirements, thereby improving the aging quality and quality of the re-roasted tobacco strips.

[0057] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0058] The object information involved in this application, including but not limited to the object device information, the object personal information, etc., and data, including but not limited to data used for analysis, stored data, displayed data, etc., are all information and data authorized by the object or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the laws, regulations and standards of relevant countries and regions.

[0059] In order to ensure that tobacco quality meets the requirements of the cigarette industry, it must go through the aging process. The essence of tobacco aging is to convert the unfavorable quality components in the tobacco leaves into favorable quality components through continuous biochemical reactions under specific environmental conditions.

[0060] Tobacco leaf aging is divided into natural aging and artificial aging.

[0061] Natural aging refers to the storage of tobacco leaves under natural conditions such as temperature and humidity. However, natural aging has problems such as being prone to mold and insects and being greatly affected by weather factors, which often makes the aging effect less than ideal.

[0062] Artificial aging refers to the process of manually controlling temperature, humidity, oxygen, carbon dioxide, and other conditions to accelerate the aging process and maintain the quality of redried tobacco strips. Controlled atmosphere aging has become a common artificial aging method used in the storage and maintenance of redried tobacco strips.

[0063] During the controlled atmosphere aging process, relative humidity is a key factor affecting tobacco leaves and determining the transformation of their internal components. Research has shown that an air humidity between 55% and 65% is most conducive to improving tobacco aging quality. Under appropriate humidity conditions, tobacco leaves' appearance, physical properties, and smoking quality are significantly improved. Excessively high humidity can cause tobacco leaves to mold and deteriorate, affecting their quality. Excessively low humidity can cause tobacco leaves to become dry and brittle, hindering aging.

[0064] However, when adjusting the relative humidity, the staff currently relies on experience to adjust the temperature, humidity, oxygen or carbon dioxide content in the storage environment, and then observe the real-time values ​​of the temperature and humidity sensors to ensure that the real-time values ​​of the temperature and humidity sensors meet the relative humidity requirements. However, this will result in the adjusted relative humidity not meeting the aging requirements.

[0065] In order to solve the above technical problems, the present application proposes a method for regulating the relative humidity of the smoke-conditioned storage environment of redried slices.

[0066] Figure 1 This is a flow chart of a relative humidity control method for a smoke-conditioned storage environment of redried slices provided in an embodiment of the present application, as shown in FIG. Figure 1 As shown, the relative humidity adjustment of the smoke-conditioned storage environment of the redried slices includes the following steps S101-S106:

[0067] S101: Obtaining a target equilibrium relative humidity range for redried tobacco strips;

[0068] S102: Obtaining a first target controlled atmosphere parameter of a first controlled atmosphere storage environment for the redried tobacco strips, and a second target controlled atmosphere parameter of a second controlled atmosphere storage environment for the redried tobacco strips; wherein, the outer sides of the redried tobacco strips are, from the outside to the inside, a first packaging body and a second packaging body, and the first controlled atmosphere storage environment is the environment between the first packaging body and the second packaging body; the first target controlled atmosphere parameter is a parameter related to the relative humidity in the first controlled atmosphere storage environment; the second controlled atmosphere storage environment is the environment within the first packaging body; and the second target controlled atmosphere parameter is a parameter related to the relative humidity in the second controlled atmosphere storage environment;

[0069] S103: Determining a first real-time relative humidity in a non-refried tobacco strip environment based on the first target atmosphere conditioning parameter and a relative humidity model for non-refried tobacco strips, and determining a second real-time relative humidity in a refried tobacco strip environment based on the second target atmosphere conditioning parameter and a relative humidity model for refried tobacco strips;

[0070] S104: Determining whether the target equilibrium relative humidity range is met based on the first real-time relative humidity, the second real-time relative humidity, and their respective humidity coefficients;

[0071] S105: If not satisfied, determining a target gas conditioning parameter adjustment value for the first target gas conditioning parameter and / or the second target gas conditioning parameter according to the target equilibrium relative humidity range; wherein the preset target gas conditioning parameter is included in the first target gas conditioning parameter and / or the second target gas conditioning parameter;

[0072] S106: Adjusting the first target gas conditioning parameter and / or the second target gas conditioning parameter according to the target gas conditioning parameter adjustment value, so that the first gas conditioning storage environment and the second gas conditioning storage environment meet the target equilibrium relative humidity range.

[0073] In step S101, a target equilibrium relative humidity range of the redried tobacco strips is obtained, where the target equilibrium relative humidity range is a humidity value interval that meets the aging requirements of the redried tobacco strips.

[0074] Thereafter, a first target atmosphere-controlled parameter of the first atmosphere-controlled storage environment in which the redried tobacco strips are stored and a second target atmosphere-controlled parameter of the second atmosphere-controlled storage environment in which the redried tobacco strips are stored are obtained.

[0075] The outer sides of the redried tobacco strips are the first packaging body and the second packaging body from the outside to the inside, and the first controlled atmosphere storage environment is the environment between the first packaging body and the second packaging body; the first target controlled atmosphere parameter is a parameter that affects the relative humidity in the first controlled atmosphere storage environment.

[0076] During the actual aging process, the re-roasted tobacco leaves will be placed in a box, and then a layer of film will be wrapped around the outside of the box.

[0077] In a feasible embodiment of the present application, the first packaging body is a film, the second packaging body is a box body, the first controlled atmosphere storage environment is the environment between the film and the box body, that is, the first controlled atmosphere storage environment is an environment without re-roasted tobacco strips, and the second controlled atmosphere storage environment is the environment inside the box body, that is, the second controlled atmosphere storage environment is an environment with re-roasted tobacco strips.

[0078] At this time, a sensor placed in the first controlled atmosphere storage environment can be used to obtain a real-time value of the first target atmosphere parameter in the first controlled atmosphere storage environment. For example, a temperature sensor can be used to obtain a temperature value, and a nitrogen concentration sensor can be used to obtain a nitrogen concentration.

[0079] The first real-time relative humidity in the non-re-roasted tobacco strip environment is obtained according to the real-time value of the first target atmosphere conditioning parameter and the relative humidity model of the non-re-roasted tobacco strips.

[0080] In a feasible implementation, it is also necessary to obtain a relative humidity model of non-re-cured tobacco strips, which may include the following sub-steps A1-A4:

[0081] A1. Obtaining first atmosphere parameters of a first experimental atmosphere storage environment in a non-re-cured tobacco strip environment. The first atmosphere parameters include: nitrogen volume concentration, temperature, and oxygen volume concentration.

[0082] A2. Obtaining a first key indicator parameter affecting relative humidity in a non-re-cured tobacco strip environment from the first controlled atmosphere parameter, the first key parameter being a first target controlled atmosphere parameter.

[0083] A3. Obtain the real-time relative humidity value of the first experimental controlled atmosphere storage environment.

[0084] A4. Obtain a relative humidity model for non-re-roasted tobacco strips based on the first key parameter and the real-time relative humidity value of the first experimental controlled atmosphere environment.

[0085] Specifically, step A2 may further include the following sub-steps A21-A23:

[0086] A21. Obtain the influence coefficient of each atmosphere-conditioning parameter in the first atmosphere-conditioning parameter on relative humidity through SPSS analysis software.

[0087] A22. Determine a target first influence coefficient among the first influence coefficients that is greater than a first preset value.

[0088] A23. Determine the first controlled atmosphere parameter corresponding to the target first influence coefficient as the first key parameter.

[0089] In this step, the key influencing parameters of relative humidity in the non-re-cured tobacco environment will be screened.

[0090] The first experimental controlled atmosphere storage environment is a non-reheated smoke gas environment at a balanced relative humidity. The first controlled atmosphere parameters obtained at this time include nitrogen volume concentration, temperature, oxygen volume concentration and other factors.

[0091] As shown in Table 1, the influence coefficient of each air conditioning parameter on relative humidity in the first air conditioning parameter is obtained by SPSS analysis software:

[0092] Table 1

[0093]

[0094] Among them, * indicates that the significance level reaches 0.05.

[0095] That is, the first preset value is 0.05, and the first key parameters obtained at this time are nitrogen volume concentration and temperature.

[0096] The data were analyzed by variance analysis using SPSS analysis software, and the oxygen volume concentration factor was eliminated. It was found that nitrogen volume concentration and temperature had significant effects on the relative humidity of the non-re-cured tobacco environment.

[0097] After obtaining the first key parameter, the corresponding relationship between the relative humidity of uncured tobacco strips and the independent variable is constructed:

[0098] ;

[0099] Wherein, Y1 represents the relative humidity of the controlled atmosphere environment of the unre-cured tobacco strips; A is the volume concentration of nitrogen; B is the temperature; M, N, K, P and Q are the required coefficients.

[0100] After obtaining the first key parameter, the relative humidity model of non-re-cured tobacco strips can be obtained by substituting each set of values ​​into the above formula:

[0101] .

[0102] After obtaining the relative humidity model of non-re-roasted tobacco strips, actual warehouse data will be used to verify the relationship of the relative humidity model of non-re-roasted tobacco strips to ensure the accuracy of the relative humidity model of non-re-roasted tobacco strips.

[0103] The obtained verification table is shown in Table 2:

[0104] Table 2

[0105]

[0106] Laboratory data was used to validate the relative humidity model for unrefried tobacco strips and calculate the relative error. The absolute value of the relative humidity error for the unrefried controlled atmosphere environment was within 10%, indicating that the relative humidity model for unrefried tobacco strips is relatively accurate and meets the requirements for real-world warehouse applications.

[0107] After obtaining the first target atmosphere parameters of the first atmosphere-controlled storage environment where the redried tobacco strips are stored, the first real-time relative humidity can be obtained by substituting these real-time values ​​into the above formula.

[0108] After obtaining a second target controlled atmosphere parameter for the second controlled atmosphere storage environment in which the redried tobacco strips are stored, a second real-time relative humidity in the redried tobacco strip environment is obtained based on the real-time value of the second target controlled atmosphere parameter and the relative humidity model for the redried tobacco strips. The second controlled atmosphere storage environment is the environment within the first packaging body; the second target controlled atmosphere parameter is a parameter that affects the relative humidity in the second controlled atmosphere storage environment.

[0109] In a feasible implementation, a relative humidity model of redried tobacco strips may be obtained, specifically, including the following sub-steps B1-B4:

[0110] B1. Obtaining second controlled atmosphere parameters of a second experimental controlled atmosphere storage environment in the presence of redried tobacco strips. The second controlled atmosphere parameters include: the first key parameter and moisture content of the redried tobacco strips.

[0111] The second gas conditioning parameters at this time specifically include: the first key parameters (nitrogen volume concentration, temperature), the moisture content of the redried tobacco strips (including the moisture content of the redried tobacco strips, the square of the moisture content of the redried tobacco strips), various combinations of the first key parameters (the square of the nitrogen volume concentration, the square of the temperature, the product of the nitrogen volume concentration and the temperature), and the combination of the first key parameters and the moisture content of the redried tobacco strips (the product of the nitrogen volume concentration and the moisture content of the redried tobacco strips, the product of the temperature and the moisture content of the redried tobacco strips).

[0112] B2. Obtaining a second key parameter affecting relative humidity in a redried tobacco strip environment from the second controlled atmosphere parameter, where the second key parameter is a second target controlled atmosphere parameter;

[0113] B3. Obtain the real-time relative humidity value of the second experimental controlled atmosphere storage environment;

[0114] B4. Obtain a relative humidity model for redried tobacco strips based on the second key parameter and the real-time relative humidity value of the second experimental controlled atmosphere environment.

[0115] Specifically, step B2 may include the following sub-steps B21-B23:

[0116] B21. Obtain the second influence coefficient of each of the second atmosphere conditioning parameters on relative humidity through SPSS analysis software.

[0117] B22. Determine a target second influence coefficient among the second influence coefficients that is greater than a second preset value.

[0118] B23. Determine the second controlled atmosphere parameter corresponding to the target second influence coefficient as the second key parameter.

[0119] Redried tobacco strips are added on the basis of steps A1-A4. In this step, the key influencing parameters of relative humidity in the redried tobacco strip environment are screened.

[0120] The second experimental controlled atmosphere storage environment was a balanced relative humidity environment containing redried tobacco strips. The second controlled atmosphere parameters obtained at this time included factors such as nitrogen volume concentration, temperature, and redried tobacco strip moisture content. Because the addition of redried tobacco strip samples affects relative humidity, redried tobacco strip moisture content was added to the aforementioned screening parameters.

[0121] As shown in Table 3, the influence coefficient of each air conditioning parameter on relative humidity in the second air conditioning parameter was obtained by variance analysis of the response surface regression equation, and the second key parameter was selected according to the P value:

[0122] Table 3

[0123]

[0124] Among them, ** indicates extremely significant difference (P<0.01), and * indicates significant difference (P<0.05). 2 =0.9980, corrected R 2 =0.9955.

[0125] That is, the second preset value is 0.05, and the second key parameters obtained at this time are nitrogen volume concentration and temperature.

[0126] The second key parameters screened out at this time are: nitrogen volume concentration, temperature, moisture content, the product of nitrogen volume concentration and moisture content of redried tobacco strips, the product of temperature and moisture content of redried tobacco strips, the square of nitrogen volume concentration and the square of moisture content of redried tobacco strips.

[0127] After obtaining the second key parameter, the corresponding relationship between the relative humidity of redried tobacco strips and the independent variable is first constructed:

[0128] ;

[0129] Among them, Y2 represents the relative humidity of the atmosphere of the redried tobacco strips; A is the volume concentration of nitrogen; B is the temperature, C is the moisture content of the redried tobacco strips, and D, E, F, G, H, J, L and R are the required coefficients.

[0130] After obtaining the second key parameter, the relative humidity model of redried tobacco strips can be obtained by substituting each set of values ​​into the above formula:

[0131] ;

[0132] After obtaining the relative humidity model of re-roasted tobacco strips, the real warehouse data will be used to verify the relationship of the relative humidity model of re-roasted tobacco strips to ensure the accuracy of the relative humidity model of re-roasted tobacco strips.

[0133] The obtained verification table is shown in Table 4:

[0134] Table 4

[0135]

[0136] Laboratory data was used to validate the relative humidity model for redried tobacco strips and calculate the relative error. The absolute error in relative humidity in the controlled atmosphere containing redried tobacco strips was within 4%, indicating that the relative humidity model for redried tobacco strips is relatively accurate and meets the requirements for real-world warehouse applications.

[0137] After obtaining the real-time values ​​of the second target atmosphere parameters of the second atmosphere storage environment where the redried tobacco strips are located, the second real-time relative humidity can be obtained by substituting these real-time values ​​into the above formula.

[0138] In step S105, it is necessary to determine whether the target equilibrium relative humidity range is met based on the first real-time relative humidity, the second real-time relative humidity and their respective humidity coefficients. Here, there is no limitation on the humidity coefficients of the first real-time relative humidity and the second real-time relative humidity, and they can be set by technicians in this field. For example, they can both be set to 1, or other humidity coefficient ratios can be used.

[0139] In step S106, when it is detected that the first real-time relative humidity and the second real-time relative humidity do not meet the requirements of the target equilibrium relative humidity range, the target atmosphere adjustment value of the first target atmosphere parameter and / or the second target gas atmosphere parameter is determined according to the target equilibrium relative humidity range; wherein the preset target atmosphere parameter is included in the first target atmosphere parameter and / or the second target gas atmosphere parameter.

[0140] The requirement of meeting the target equilibrium relative humidity range may include: being the same as the target equilibrium relative humidity range, or a difference between the target equilibrium relative humidity range and the target equilibrium relative humidity range meeting a preset threshold.

[0141] In a feasible implementation, step S106 includes the following sub-steps C1-C3:

[0142] C1. Obtain an average value of the first real-time relative humidity and the second real-time relative humidity.

[0143] C2. Check whether the average value meets the requirements of the target equilibrium relative humidity range.

[0144] C3. If the average value does not meet the requirements of the target equilibrium relative humidity range, determine the target atmosphere parameter adjustment value for the first target atmosphere parameter and / or the second target atmosphere parameter according to the target equilibrium relative humidity range.

[0145] Among them, the first real-time relative humidity can also be considered as the relative humidity in the environment without re-roasted tobacco strips, and the second real-time relative humidity can also be considered as the relative humidity in the environment with re-roasted tobacco strips. Since the environments without re-roasted tobacco strips and the environments with re-roasted tobacco strips are interchangeable, when the volume of the first controlled atmosphere storage environment is the same as the volume of the second controlled atmosphere storage environment, the relative humidity after equilibrium between the environment without re-roasted tobacco strips and the environment with re-roasted tobacco strips can be determined based on the first real-time relative humidity in the environment without re-roasted tobacco strips and the second real-time relative humidity in the environment with re-roasted tobacco strips. If the relative humidity after equilibrium does not meet the requirements of the target equilibrium relative humidity range, the target atmosphere parameter adjustment value of the first target atmosphere parameter and / or the second target gas atmosphere parameter will be determined according to the target equilibrium relative humidity range.

[0146] When the volume of the first controlled atmosphere storage environment is different from the volume of the second controlled atmosphere storage environment, the volume ratio in the ideal gas state equation can be referred to, and then the ratio of the first real-time relative humidity in the non-re-roasted tobacco environment to the second real-time relative humidity in the re-roasted tobacco environment can be adjusted accordingly to meet the equilibrium relative humidity requirements.

[0147] During the experiment, a modified atmosphere composite film bag with a thickness of 8 filaments, 45mm x 65mm, was used to meet airtightness requirements. 900g of tobacco strips were placed. This was chosen because, during laboratory controlled atmosphere storage of small samples, the tobacco strips reach a certain aging period, which facilitates physical, chemical, and sensory analysis, thus meeting quality testing requirements. A temperature and humidity monitor was placed inside the modified atmosphere composite film bag. Due to the desorption and adsorption effects of the tobacco strips, it takes time for the relative humidity inside the modified atmosphere composite film bag to reach equilibrium. The equilibrium relative humidity was determined by maintaining the data within a fluctuation range of no more than 0.1% for 2-3 days.

[0148] In another embodiment, step S106 includes the following sub-steps D1-D2, and step S107 includes the following sub-step D3:

[0149] D1. Obtaining adjustable gas conditioning parameters from among the first target gas conditioning parameters and / or the second target gas conditioning parameters.

[0150] D2. Obtain adjustment values ​​of adjustable gas conditioning parameters according to the target equilibrium relative humidity range.

[0151] D3. Adjust the adjustable atmosphere control parameters according to the adjustment values ​​of the adjustable atmosphere control parameters.

[0152] For example, the adjustable atmosphere control parameter is the nitrogen volume concentration in the first atmosphere control storage environment.

[0153] Some parameters of the first target gas conditioning parameters or the second target gas conditioning parameters may not be adjustable. Therefore, these parameters should be ignored when determining the adjustment value. For example, if the temperature cannot be changed, then when determining the adjustment value, the temperature adjustment value cannot be calculated. For another example, the moisture content of the re-cured tobacco sheets cannot be changed, then when determining the adjustment value, the moisture content adjustment value of the re-cured tobacco sheets cannot be calculated.

[0154] Specifically, the target gas conditioning parameter adjustment value of the first target gas conditioning parameter and / or the second target gas conditioning parameter can be determined by the following steps: when it is determined that the gas conditioning parameter that cannot be adjusted is moisture content, temperature, etc., and it is determined that the adjustable gas conditioning parameter is nitrogen volume concentration, the existing gas conditioning parameters are substituted into the model to calculate the first real-time relative humidity and the second real-time relative humidity.

[0155] Obtain the target equilibrium humidity. Substitute the model equation to calculate the nitrogen volume concentration within the range of the real-time relative humidity and the target equilibrium relative humidity. The nitrogen volume concentration adjustment value is the difference between the nitrogen volume concentrations at the two humidity levels.

[0156] For example, for smoke conditioning storage of redried slices with a moisture content of 10%, the temperature is 30°C at a nitrogen volume concentration of 50%. Using the model relationship:

[0157] ;

[0158] Substituting A = 50%, B = 30°C, and C = 10%, we obtain the real-time relative humidity Y2 = 50.7% under the flue gas conditioning condition for the re-baked chips. The target equilibrium relative humidity range Y is 53.4% ​​(based on different alcoholization requirements). Substituting Y = 53.4% ​​into the model equation corresponding to Y2 yields a nitrogen volume concentration A1 = 87%. The difference between A1 and A is the adjusted nitrogen volume concentration of 37%.

[0159] At the same time, the relative humidity in the smoke conditioning environment without re-baking is calculated using the model relationship:

[0160] ;

[0161] Substituting A = 50% and B = 30°C, the real-time relative humidity in the smoke-conditioned environment without reheating is Y1 = 47.3%. Substituting Y = 53.4% ​​into the model equation corresponding to Y1, we obtain the nitrogen volume concentration A2 = 99%. The difference between A2 and A is the adjusted nitrogen volume concentration of 44%.

[0162] When making adjustments, you can adjust from the inside out, that is, first adjust the nitrogen concentration in the first package (with re-roasted sheets and smoke conditioning environment), and then adjust the nitrogen concentration between the first package and the second package (without re-roasted sheets and smoke conditioning environment). Specifically, first adjust the nitrogen concentration in the smoke conditioning environment with re-roasted sheets to 37%, and then adjust the nitrogen concentration in the smoke conditioning environment without re-roasted sheets to 44%.

[0163] In an embodiment of the present application, a relative humidity model for non-re-roasted tobacco strips is established by using parameters that affect the relative humidity in the environment between the first packaging body and the second packaging body, and a relative humidity model for re-roasted tobacco strips is established by using parameters that affect the relative humidity in the environment inside the second packaging body. During actual adjustment, the real-time value of the first target atmosphere parameter in the environment between the first packaging body and the second packaging body is obtained in combination with the relative humidity model for non-re-roasted tobacco strips to obtain the first real-time relative humidity, and the real-time value of the second target atmosphere parameter in the environment inside the first packaging body is obtained in combination with the relative humidity model for re-roasted tobacco strips to obtain the second real-time relative humidity. Combined with the obtained target equilibrium relative humidity range for re-roasted tobacco strips, when it is detected that the first real-time relative humidity and the second real-time relative humidity are not When the requirements of the target equilibrium relative humidity range are met, the target atmosphere conditioning parameter adjustment value of the first target atmosphere conditioning parameter and / or the second target atmosphere conditioning parameter is determined according to the target equilibrium relative humidity range, and the preset target atmosphere conditioning parameter is automatically adjusted according to the target atmosphere conditioning parameter adjustment value, so that the first controlled atmosphere storage environment and the second controlled atmosphere storage environment meet the target equilibrium relative humidity range. Since the equilibrium relative humidity is used as the basis point, the adjustment parameters are obtained by referring to the environment with re-roasted tobacco strips and the environment without re-roasted tobacco strips, and the relative humidity of the atmosphere conditioning environment of the re-roasted tobacco strips is automatically regulated, so that the relative humidity of the re-roasted tobacco strips moves in a direction that is conducive to the aging of the tobacco strips, so that the adjusted relative humidity is more in line with the aging requirements, thereby improving the aging quality and quality of the re-roasted tobacco strips.
