Description

Technical Field

[0001] This invention relates to the field of production control technology, specifically to a production control method, system, and production process for cassia seed tea. Background Technology

[0002] Currently, cassia seed is a plant widely used in traditional Chinese medicine. Its seeds are usually used to make cassia seed tea. The quality of cassia seed directly affects the quality and efficacy of the tea. The production control method of cassia seed tea is a multi-stage and multi-factor systematic project. From the selection of raw materials and the control of processing technology to quality testing, packaging and storage, all aspects need to be strictly controlled. With the advancement of production technology, modern cassia seed tea production also focuses on the introduction of automated equipment and refined quality control measures to ensure the stability of tea quality and efficacy.

[0003] For example, the invention patent with announcement number CN107183227B announces an intelligent tea production line, including a mechanical system and an electrical control system; the mechanical system includes a fixation machine, a cooling air separator, a rolling device, a circulating fixation secondary machine, and a circulating drying machine; the cooling air separator includes a cooling fan, a cooling conveyor belt, and an air separator; the rolling device includes a dispensing conveyor, four rolling machines, and a rolling device discharge conveyor belt; the circulating fixation secondary machine includes a fixation secondary machine guide hopper, a fixation secondary machine rotating inner cylinder, and a fixation secondary machine fixed outer cylinder, etc.; the circulating drying machine includes a drying machine rotating inner cylinder and a drying machine fixed outer cylinder, etc.; the electrical control system includes a main control unit, a sensor unit, a power supply unit, a controller unit, and a terminal control unit.

[0004] For example, the invention patent with publication number CN119045397A discloses an intelligent control system and method for automated production of black tea. First, the tea leaves are classified and allocated according to their variety, grade, and maturity to obtain classified tea leaves. Next, the classified tea leaves are heat-treated to obtain withered tea leaves. Then, the withered tea leaves are squeezed, rubbed, and twisted to obtain rolled tea leaves. Next, the temperature is controlled in real time to cause the polyphenols in the rolled tea leaves to oxidize, forming red pigments and aroma substances to obtain fermented tea leaves. Then, the fermented tea leaves are dried to obtain dried tea leaves. Next, the dried tea leaves are graded to obtain sieved tea leaves. Finally, the sieved tea leaves are sealed and packaged to obtain the finished black tea product.

[0005] However, in the process of implementing the inventive technical solution in the embodiments of this application, it was found that the above-mentioned technology has at least the following technical problems:

[0006] Existing tea production control methods directly control the production of tea. However, the control equipment based on this method may have inaccurate control precision, which may lead to the failure to detect and handle abnormalities in the production process in a timely manner, thereby affecting the production quality of cassia seed tea. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a production control method, system, and production process for cassia seed tea, which can effectively solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: The first aspect of the present invention provides a production control method for cassia seed tea, comprising: cassia seed raw material pretreatment: performing a first pretreatment on the cassia seed raw material, obtaining the quality data of the cassia seed raw material after the first pretreatment and the processing data during the pretreatment process, comprehensively analyzing to obtain the cassia seed pretreatment quality index, and comparing it with the cassia seed pretreatment quality index threshold preset in the production database to obtain the pretreatment comparison result, and determining whether the pretreatment process of the cassia seed raw material needs to be controlled based on the pretreatment comparison result.

[0009] Cassia seed tea production: The pre-treated cassia seed raw materials are used to produce cassia seed tea. Production data and environmental data during the production process are obtained and comprehensively analyzed with the cassia seed pre-treatment quality index to obtain the cassia seed tea production quality index. This index is then compared with the preset cassia seed tea production quality index definition value in the production database to obtain the production comparison result. Based on the production comparison result, it is determined whether the production process of cassia seed tea needs to be controlled.

[0010] Cassia seed tea testing: After production, the cassia seed tea is marked as packageable cassia seed tea and packaged. The packaged cassia seed tea is marked as cassia seed tea bag. Through the packaging process of packageable cassia seed tea, environmental data and packaging quality data are obtained during the packaging process. The comprehensive analysis yields the cassia seed tea packaging quality index, which is compared with the preset cassia seed tea packaging quality index threshold in the production database to obtain the packaging quality comparison result. Finally, based on the packaging quality comparison result, it is determined whether the packaging process of cassia seed tea needs to be controlled.

[0011] As a further method, the specific analysis process of the Cassia seed pretreatment quality index is as follows:

[0012] The difference between the real-time washing and stirring frequency of the cassia seed raw material during the pretreatment cycle and the preset reference stirring frequency in the production database is processed to obtain the difference in the real-time washing and stirring frequency of the cassia seed raw material during the pretreatment cycle.

[0013] The difference between the real-time water temperature of the cassia seed raw material during the pretreatment cycle and the preset reference water temperature in the production database is processed to obtain the real-time water temperature difference of the cassia seed raw material during the pretreatment cycle.

[0014] The average content of harmful substances, the ratio of impurities, the ratio of moisture, the washing time of the cassia seed raw material during the first pretreatment cycle, the difference in real-time washing and stirring frequency, and the difference in real-time water temperature were comprehensively analyzed to obtain the cassia seed pretreatment quality index.

[0015] As a further method, the determination of whether the pretreatment process of cassia seed raw materials needs to be controlled based on the pretreatment comparison results is as follows:

[0016] If the pretreatment quality index of cassia seeds is greater than or equal to the pretreatment quality index threshold preset in the production database, the pretreatment comparison result will be recorded as a qualified pretreatment result, and the cassia seed raw materials that have completed the first pretreatment will be directly used for cassia seed tea production.

[0017] If the pretreatment quality index of cassia seeds is less than the pretreatment quality index threshold preset in the production database, the pretreatment comparison result will be recorded as a pretreatment failure result.

[0018] If the pretreatment comparison result is unqualified, then the pretreatment process of cassia seed raw materials needs to be controlled.

[0019] The pretreatment process of cassia seed raw materials is controlled, specifically by extending the washing time of cassia seed raw materials in the pretreatment cycle, accelerating the real-time washing and stirring frequency, and performing a second pretreatment on cassia seed raw materials. The quality data of cassia seed raw materials after the second pretreatment and the processing data during the second pretreatment process are obtained, and the quality index of the second pretreatment of cassia seeds is analyzed.

[0020] The second pretreatment is based on the first pretreatment method, which involves extending the washing time and increasing the real-time washing and stirring frequency.

[0021] If the quality index of the second pretreatment of cassia seeds is greater than or equal to the threshold of the pretreatment quality index of cassia seeds preset in the production database, then the cassia seed raw materials after the second pretreatment will be directly used for cassia seed tea production, and the quality index of the second pretreatment of cassia seeds will be recorded as the quality index of the pretreatment of cassia seeds.

[0022] If the quality index of the secondary pretreatment of cassia seeds is less than the preset threshold of the quality index of cassia seed pretreatment in the production database, an early warning will be issued directly for the cassia seed raw materials.

[0023] As a further method, the specific analysis process for the Mingzi tea packaging quality index is as follows:

[0024] The frying time of cassia seed tea during the production cycle is matched with the moisture content threshold of cassia seed tea corresponding to each frying time interval preset in the production database to obtain the preset moisture content threshold of cassia seed tea.

[0025] The average moisture content of cassia seed tea during the packaging period is obtained and compared with the preset moisture content threshold of cassia seed tea in the production database to obtain the moisture content ratio of cassia seed tea during the packaging period.

[0026] To obtain the average content of harmful substances in cassia seed tea during its packaging cycle.

[0027] The environmental data during the packaging process specifically includes the real-time humidity and average electrostatic voltage of the environment in which the cassia seed tea is packaged.

[0028] The packaging quality data specifically includes the average sealing strength, average gas leakage rate, and average weight of the cassia seed tea bags during the packaging period.

[0029] The packaging quality index of cassia seed tea is obtained by comprehensively analyzing the moisture content ratio, average content of harmful substances, production quality indicators, real-time humidity, average electrostatic voltage, average sealing strength, average gas leakage rate, and average weight of the cassia seed tea bags during the packaging period. The specific analysis method is as follows:

[0030] ;

[0031] In the formula, The quality index for cassia seed tea packaging is given by 'e', ​​where 'e' is a natural constant. This is the starting point of the packaging cycle. This is the end point of the packaging cycle. Any point in time within the packaging cycle. , Within the packaging cycle of cassia seed tea Real-time humidity of the environment at a given time point. The reference humidity preset for the production database, The average electrostatic voltage, The electrostatic reference voltage preset for the production database, For average sealing strength, The sealing reference strength is preset for the production database. The average gas leakage rate, The packaging impact index corresponding to the unit value of the average gas leakage rate preset for the production database.

Average weight The reference weight preset for the production database. This represents the average content of harmful substances. Packaging impact indicators corresponding to the unit values ​​of hazardous substance content preset for the production database.

[0032] As a further method, the final determination of whether the packaging process of cassia seed tea needs to be controlled based on the packaging quality comparison results is as follows:

[0033] If the packaging quality index of cassia seed tea is greater than or equal to the preset threshold of the packaging quality index of cassia seed tea in the production database, then the packaging quality comparison result will be recorded as the first comparison result of the packaging.

[0034] If the packaging quality index of cassia seed tea is less than the preset threshold of the packaging quality index of cassia seed tea in the production database, the packaging quality comparison result will be recorded as the second packaging comparison result.

[0035] If the packaging quality comparison result is the second best result, then the packaging process of cassia seed tea needs to be controlled.

[0036] The second aspect of the present invention provides a production control system for cassia seed tea, comprising: a cassia seed raw material pretreatment module, used to perform a first pretreatment on the cassia seed raw material, acquire quality data of the cassia seed raw material after the first pretreatment and processing data during the pretreatment process, comprehensively analyze to obtain a cassia seed pretreatment quality index, compare it with a cassia seed pretreatment quality index threshold preset in the production database to obtain a pretreatment comparison result, and determine whether the pretreatment process of the cassia seed raw material needs to be controlled based on the pretreatment comparison result.

[0037] The cassia seed tea production module is used to produce cassia seed tea from pre-treated cassia seed raw materials. It acquires production data and environmental data during the production process, performs comprehensive analysis with the cassia seed pre-treatment quality index, obtains the cassia seed tea production quality index, and compares it with the preset cassia seed tea production quality index definition value in the production database to obtain the production comparison result. Based on the production comparison result, it determines whether the production process of cassia seed tea needs to be controlled.

[0038] The cassia seed tea detection module is used to mark the produced cassia seed tea as packageable and perform packaging operations. The packaged cassia seed tea is marked as a cassia seed tea bag. Through the packaging process of packageable cassia seed tea, environmental data and packaging quality data are acquired during the packaging process. The comprehensive analysis yields the cassia seed tea packaging quality index, which is compared with the preset cassia seed tea packaging quality index threshold in the production database to obtain the packaging quality comparison result. Finally, based on the packaging quality comparison result, it is determined whether the packaging process of cassia seed tea needs to be controlled.

[0039] The third aspect of the present invention provides a production process for cassia seed tea, characterized in that it includes: pretreatment of cassia seed raw materials, production of cassia seed tea, and packaging of cassia seed tea.

[0040] The pretreatment of the cassia seed raw material specifically includes screening, washing, and impurity removal of the cassia seed raw material.

[0041] The production of cassia seed tea involves soaking and roasting the pre-treated cassia seed raw materials in sequence.

[0042] The packaging of the cassia seed tea involves cooling the roasted cassia seed tea before packaging it.

[0043] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0044] (1) By acquiring the quality data of the first pretreatment of cassia seed raw materials and the processing data during the pretreatment process, this invention can effectively monitor and evaluate the pretreatment quality of cassia seed raw materials, promptly identify and resolve potential problems during the pretreatment process, ensure the stability of the quality of cassia seed raw materials, and obtain the cassia seed pretreatment quality index through comprehensive analysis. This can more scientifically and accurately evaluate the pretreatment quality of cassia seed raw materials, provide a reference for subsequent production, and compare it with the cassia seed pretreatment quality index threshold preset in the production database to determine whether the pretreatment process of cassia seed raw materials needs to be controlled, ensuring that the pretreatment process parameters can be adjusted in a timely manner to ensure that the pretreatment quality of cassia seed raw materials meets the expected requirements.

[0045] (2) By acquiring production data and environmental data during the production process of cassia seed tea, this invention can monitor and evaluate the production process of cassia seed tea, promptly identify and resolve potential problems during production, ensure the stable quality of cassia seed tea, and conduct comprehensive analysis with the cassia seed pretreatment quality index to obtain the production quality index of cassia seed tea. This allows for a more scientific and accurate evaluation of the production process quality of cassia seed tea, providing a reference for subsequent packaging. Furthermore, it can be compared with the preset production quality index definition value of cassia seed tea in the production database to determine whether the production process of cassia seed tea needs to be controlled, and adjust the production process parameters in a timely manner to ensure that the production process quality of cassia seed tea meets the expected requirements.

[0046] (3) By acquiring environmental data and packaging quality data during the packaging process, this invention can monitor and evaluate the packaging process of cassia seed tea, promptly identify and resolve potential problems during the packaging process, ensure stable packaging quality of cassia seed tea, and obtain a comprehensive analysis of the cassia seed tea packaging quality index. This allows for a more scientific and accurate evaluation of the packaging quality of cassia seed tea. By comparing the index with the preset threshold of the cassia seed tea packaging quality index in the production database, it can be determined whether the packaging process of cassia seed tea needs to be controlled, and the packaging process parameters can be adjusted in a timely manner to ensure that the packaging quality of cassia seed tea meets the expected requirements. Attached Figure Description

[0047] The present invention will be further described with reference to the accompanying drawings, but the embodiments in the drawings do not constitute any limitation on the present invention. For those skilled in the art, other drawings can be obtained based on the following drawings without creative effort.

[0048] Figure 1 This is a schematic diagram of the method steps of the present invention.

[0049] Figure 2 This is a schematic diagram of the system module connections of the present invention. Detailed Implementation

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0051] Reference Figure 1As shown, the first aspect of the present invention provides a production control method for cassia seed tea, comprising: cassia seed raw material pretreatment: performing a first pretreatment on the cassia seed raw material, obtaining quality data of the cassia seed raw material after the first pretreatment and processing data during the pretreatment process, comprehensively analyzing to obtain a cassia seed pretreatment quality index, and comparing it with a preset cassia seed pretreatment quality index threshold in the production database to obtain a pretreatment comparison result, and determining whether the pretreatment process of the cassia seed raw material needs to be controlled based on the pretreatment comparison result.

[0052] It should be explained that the first pretreatment of cassia seed raw materials specifically includes screening, washing and removing impurities. In this embodiment, screening and removing impurities involves first using a fine sieve with a 2 mm aperture to remove chaff, small particles, sand, and ash, which are then discarded; then using a 2.5 mm aperture sieve to screen out cassia seed raw materials with a particle size of 2.5-3.5 mm; washing the cassia seed raw materials with water; and rinsing off the moisture from the cassia seed raw materials.

[0053] Cassia seed tea production: The pre-treated cassia seed raw materials are used to produce cassia seed tea. Production data and environmental data during the production process are obtained and comprehensively analyzed with the cassia seed pre-treatment quality index to obtain the cassia seed tea production quality index. This index is then compared with the preset cassia seed tea production quality index definition value in the production database to obtain the production comparison result. Based on the production comparison result, it is determined whether the production process of cassia seed tea needs to be controlled.

[0054] It needs to be explained that the production method for cassia seed tea using pre-treated cassia seed raw materials involves first flat-pressing the cassia seeds with a roller. The roller spacing is adjusted according to the particle size of the cassia seeds. For larger cassia seeds, the roller spacing needs to be increased because the outer skin of large cassia seeds is thicker and requires more pressure to crack. For cassia seeds of moderate size, the roller spacing should be kept within a moderate range to ensure sufficient pressure to crack the outer skin without breaking it. For smaller cassia seeds, the roller spacing should be appropriately reduced because the outer skin of small cassia seeds is thinner, and too large a spacing may result in insufficient pressure to crack the outer skin. The goal is to make the outer skin of the cassia seeds visibly cracked but not broken. After rolling, the cassia seeds are air-dried or sun-dried. Then, the air-dried or sun-dried cassia seeds are heated and stir-fried over a low flame. During the stir-frying process, the heat is strictly controlled.

[0055] Cassia seed tea testing: After production, the cassia seed tea is marked as packageable cassia seed tea and packaged. The packaged cassia seed tea is marked as cassia seed tea bag. Through the packaging process of packageable cassia seed tea, environmental data and packaging quality data are obtained during the packaging process. The comprehensive analysis yields the cassia seed tea packaging quality index, which is compared with the preset cassia seed tea packaging quality index threshold in the production database to obtain the packaging quality comparison result. Finally, based on the packaging quality comparison result, it is determined whether the packaging process of cassia seed tea needs to be controlled.

[0056] It should be explained that the specific packaging method for packageable cassia seed tea is to cool the roasted cassia seeds to room temperature and then package them according to packaging requirements, such as packaging the cassia seed tea into 100-gram bags.

[0057] Specifically, the quality data of the cassia seed raw material after the first pretreatment includes the impurity content, moisture content, and average content of harmful substances of the cassia seed raw material after the first pretreatment.

[0058] It should be explained that the impurities in the aforementioned cassia seed raw materials include, but are not limited to, weed seeds, soil, dust, and insect residues. The impurity content of the cassia seed raw materials can be determined by directly selecting a certain amount of cassia seed sample, choosing a suitable solvent such as ethanol, acetone, n-hexane, or water, and placing the cassia seed sample in an extractor (such as a separatory funnel or reflux extraction device). An appropriate amount of solvent is added to the extractor, and the mixture is stirred or shaken. After extraction for a relatively long time, two phases usually separate: one phase is the solvent phase containing dissolved impurities, and the other phase is the undissolved cassia seed raw material. The two phases are separated using a separatory funnel, and the separated impurities are quantified. Commonly used analytical methods include thin-layer chromatography (TLC), which can be used to determine the impurity content of cassia seed raw materials; moisture content can be determined using the Karl Fischer method, employing Karl Fischer chemistry; the content of harmful substances usually refers to toxic substances that may be present in cassia seed raw materials, such as pesticide residues, heavy metals (e.g., lead, cadmium, arsenic), mycotoxins, etc., which are detected by gas chromatography (GC) to determine whether harmful substances are present and their content, and the average content of various harmful substances detected is analyzed to obtain the average content of harmful substances.

[0059] The processing data in the pretreatment process specifically includes the washing time of the cassia seed raw material during the pretreatment cycle, the real-time washing and stirring frequency, and the real-time water temperature.

[0060] It should be explained that the aforementioned pretreatment cycle usually refers to the entire time span from the time the cassia seed raw materials enter the pretreatment stage (such as screening and washing) to the completion of pretreatment and the raw materials are ready to enter the next stage (such as cassia seed tea production). The length of this cycle is related to factors such as the type of cassia seed raw materials being processed and the complexity of the pretreatment process. The washing time can be obtained by timing the washing of the cassia seed raw materials within the pretreatment cycle using a timer. The washing and stirring frequency is usually controlled by the motor speed. The motor speed is obtained by monitoring the motor speed and stirring frequency in real time using a speed sensor. The real-time water temperature is monitored in real time by an installed temperature sensor.

[0061] The impurity content of the cassia seed raw material after the first pretreatment is compared with the impurity content threshold preset in the production database to obtain the impurity content ratio of the cassia seed raw material after the first pretreatment.

[0062] The moisture content of the cassia seed raw material after the first pretreatment is compared with the moisture content threshold preset in the production database to obtain the moisture content ratio of the cassia seed raw material after the first pretreatment.

[0063] Specifically, the analysis process for the pretreatment quality index of cassia seeds is as follows:

[0064] The difference between the real-time washing and stirring frequency of the cassia seed raw material during the pretreatment cycle and the preset reference stirring frequency in the production database is processed to obtain the difference in the real-time washing and stirring frequency of the cassia seed raw material during the pretreatment cycle.

[0065] The difference between the real-time water temperature of the cassia seed raw material during the pretreatment cycle and the preset reference water temperature in the production database is processed to obtain the real-time water temperature difference of the cassia seed raw material during the pretreatment cycle.

[0066] The average content of harmful substances, the ratio of impurities, the ratio of moisture, the washing time of the cassia seed raw material during the first pretreatment cycle, the difference in real-time washing and stirring frequency, and the difference in real-time water temperature were comprehensively analyzed to obtain the cassia seed pretreatment quality index.

[0067] In this embodiment, the washing time directly affects the removal of impurities and the amount of harmful substances remaining. Too short a washing time may not be enough to remove impurities and harmful substances, while too long a washing time may result in excessive moisture content. The stirring frequency affects the washing effect, thereby affecting the removal of impurities and harmful substances. An appropriate stirring frequency helps to disperse and remove impurities and harmful substances. The water temperature affects the solubility and activity of the components in the cassia seed raw material, thereby affecting the removal of harmful substances and the dispersion of impurities.

[0068] The specific analysis method for the pretreatment quality index of Cassia seed is as follows:

[0069]

[0070] In the formula, The index for pretreatment of cassia seeds is given by , and e is the natural constant. This represents the average content of harmful substances. The ratio of impurity content, This refers to the moisture content ratio. The washing time of cassia seed raw materials during the pretreatment cycle. This is the starting time point within the preprocessing cycle. This is the end time point within the preprocessing cycle. For any point in time within the preprocessing cycle, , This represents the difference in real-time washing and stirring frequency of the cassia seed raw material at time point t during the pretreatment cycle. The allowable difference in stirring frequency preset for the production database. This represents the real-time water temperature difference of the cassia seed raw material at time point t during the pretreatment cycle. The preset allowable temperature difference for the production database The quality impact factor corresponding to the unit value of hazardous substance content preset for the production database. The quality impact factor corresponding to the unit value of impurity content is preset for the production database. The quality impact factor corresponding to the unit value of moisture content is preset for the production database. The preset reference washing time for the production database.

[0071] It should be explained that the above-mentioned average content of harmful substances refers to the average content of various harmful substances (such as pesticide residues, heavy metals, etc.) in the cassia seed raw material after the first pretreatment; the impurity content ratio refers to the ratio between the impurity content of the cassia seed raw material after the first pretreatment and the impurity content threshold preset in the production database; the moisture content ratio refers to the ratio between the moisture content of the cassia seed raw material after the first pretreatment and the moisture content threshold preset in the production database; the washing time of the cassia seed raw material in the pretreatment cycle refers to the time elapsed from the start to the end of washing during the pretreatment process; production The preset reference rinsing time in the database refers to the reference value for rinsing time set in the production database based on historical pretreatment data to guide actual pretreatment. Any point in time within the pretreatment cycle refers to any specific time point within the entire pretreatment process of the cassia seed raw material, from start to finish. This time point can be used to monitor and record various parameters during the pretreatment process, such as stirring frequency and water temperature. The real-time rinsing stirring frequency difference refers to the difference between the real-time rinsing stirring frequency of the cassia seed raw material during the pretreatment cycle and the preset reference stirring frequency in the production database. The preset stirring frequency in the production database... The allowable frequency difference refers to the maximum difference between the washing and stirring frequency and the stirring frequency set in the production database based on historical pretreatment data to guide the actual pretreatment process; the real-time water temperature difference refers to the real-time water temperature of the cassia seed raw material during the pretreatment cycle and the reference water temperature preset in the production database; the allowable water temperature difference preset in the production database refers to a maximum water temperature difference set in the production database based on historical pretreatment data; in this embodiment, in the method for analyzing the cassia seed pretreatment quality index, the average content of harmful substances, the impurity content ratio, and the moisture content of the cassia seed raw material after the first pretreatment are included. Parameters such as the ratio of raw materials, the washing time of cassia seed raw materials during the pretreatment cycle, the difference in real-time washing and stirring frequency, and the difference in real-time water temperature can be integrated into a single pretreatment quality index through nonlinear analysis. This facilitates intuitive comparison and evaluation of the pretreatment quality of cassia seed raw materials. During the nonlinear analysis, changes in each parameter will affect the final result, thus more sensitively reflecting the quality status of each stage in the pretreatment process. At the same time, standardizing each parameter (such as converting it to dimensionless values) can eliminate the dimensional differences between different parameters, making the calculation results more comparable.

[0072] It should be explained that the quality impact factor corresponding to the unit value of hazardous substance content in the production database represents the degree of influence of the unit value of hazardous substance content on the quality index of cassia seed pretreatment. The production database stores the correspondence between the unit value of hazardous substance content and its corresponding quality impact factor. For example, if the unit value of hazardous substance content is input into the production database, the production database can match the quality impact factor corresponding to the unit value of hazardous substance content. Similarly, the quality impact factor corresponding to the unit value of impurity content ratio in the production database represents the degree of influence of the unit value of impurity content ratio on the quality index of cassia seed pretreatment. The production database stores the correspondence between the unit value of impurity content ratio and its corresponding quality impact factor. For example, if the unit value of impurity content ratio is input into the production database, the production database can match the quality impact factor corresponding to the unit value of impurity content ratio. Similarly, the quality impact factor corresponding to the unit value of moisture content ratio in the production database represents the degree of influence of the unit value of moisture content ratio on the quality index of cassia seed pretreatment. The production database stores the correspondence between the unit value of moisture content ratio and its corresponding quality impact factor. For example, if the unit value of moisture content ratio is input into the production database, the production database can match the quality impact factor corresponding to the unit value of moisture content ratio.

[0073] In this embodiment, a higher impurity content ratio generally means that the cassia seed raw material contains a large number of impurities, which may include sand, pebbles, and withered branches and leaves. These impurities not only reduce the purity and quality of the cassia seeds but also interfere with subsequent processing and extraction, leading to a decrease in the pretreatment quality index. A higher moisture content ratio means that the cassia seeds were not sufficiently dried during pretreatment. High moisture content not only increases the weight and volume of the cassia seeds but also causes mold and bacterial growth. A larger or smaller washing time, i.e., a significant deviation from the preset reference washing time, indicates that too short a washing time may result in incomplete impurity removal, while a shorter washing time may lead to insufficient removal of impurities. Excessive washing time may result in the loss of active ingredients or excessive wear of cassia seeds, both of which will lead to a decrease in the pretreatment quality index. Large differences in real-time washing and stirring frequencies, even exceeding the preset allowable difference, will cause uneven washing. Too low a stirring frequency may fail to effectively remove impurities, while too high a frequency may damage the structure of cassia seeds and cause the loss of active ingredients. This uneven washing process will reduce the pretreatment quality index. Similarly, large differences in real-time water temperature, even exceeding the preset allowable difference, may cause the active ingredients in cassia seeds to be destroyed if the water temperature is too high, while too low a temperature may fail to effectively remove impurities and microorganisms. This instability in water temperature will also lead to a decrease in the pretreatment quality index. Therefore, detailed analysis of the parameters in the cassia seed pretreatment quality index can provide a more accurate understanding of the influencing factors at each stage of the pretreatment process, thereby optimizing the pretreatment process and improving the quality and safety of cassia seeds.

[0074] Furthermore, the specific determination process for whether the pretreatment process of cassia seed raw materials needs to be controlled based on the pretreatment comparison results is as follows:

[0075] If the pretreatment quality index of cassia seeds is greater than or equal to the pretreatment quality index threshold preset in the production database, the pretreatment comparison result will be recorded as a qualified pretreatment result, and the cassia seed raw materials that have completed the first pretreatment will be directly used for cassia seed tea production.

[0076] If the pretreatment quality index of cassia seeds is less than the pretreatment quality index threshold preset in the production database, the pretreatment comparison result will be recorded as a pretreatment failure result.

[0077] It should be explained that when the pre-treatment quality index of cassia seeds is greater than or equal to the preset threshold of the cassia seed pre-treatment quality index in the production database, it means that the pre-treated cassia seed raw materials have met or exceeded the preset production standards in all indicators, and all operating parameters in the pre-treatment process are controlled within a reasonable range. Therefore, these cassia seed raw materials are considered qualified products and can directly enter the subsequent cassia seed tea production process. When the pre-treatment quality index of cassia seeds is less than the preset threshold of the cassia seed pre-treatment quality index in the production database, it means that the pre-treated cassia seed raw materials have failed to meet the preset production standards in some indicators. This may be due to excessive levels of harmful substances, incomplete removal of impurities, or excessively high or low moisture content. These unqualified factors may lead to a decline in the quality of cassia seed tea. Therefore, these cassia seed raw materials are considered unqualified products, and the pre-treatment comparison results need to be recorded as unqualified pre-treatment results. Corresponding measures should be taken to handle these issues to ensure product quality and the smooth progress of the production process.

[0078] If the pretreatment comparison result is unqualified, then the pretreatment process of cassia seed raw materials needs to be controlled.

[0079] The pretreatment process of cassia seed raw materials is controlled, specifically by extending the washing time of cassia seed raw materials in the pretreatment cycle, accelerating the real-time washing and stirring frequency, and performing a second pretreatment on cassia seed raw materials. The quality data of cassia seed raw materials after the second pretreatment and the processing data during the second pretreatment process are obtained, and the quality index of the second pretreatment of cassia seeds is analyzed.

[0080] The second pretreatment is based on the first pretreatment method, which involves extending the washing time and increasing the real-time washing and stirring frequency.

[0081] In this embodiment, precise control of the pretreatment quality of cassia seed raw materials is crucial. When the pretreatment comparison result is unqualified, the pretreatment process needs to be controlled to ensure that the quality of the cassia seed raw materials after pretreatment meets production requirements. In the process of controlling the pretreatment process, adjusting the washing time and washing and stirring frequency are two key steps to improve the accuracy and efficiency of pretreatment. It should be noted that extending the washing time or increasing the real-time washing and stirring frequency can improve the pretreatment effect to a certain extent. After controlling the pretreatment process, it is still necessary to comprehensively analyze the cassia seed pretreatment quality index to more accurately reflect the overall quality change of the cassia seed raw materials during the pretreatment process. At the same time, the cassia seed raw materials corresponding to the unqualified pretreatment need to undergo a second pretreatment. The specific process of the second pretreatment is as follows: the cassia seed raw materials are screened, washed and impurities are removed again. In the second pretreatment, during the washing of the cassia seed raw materials with water, the washing time and washing and stirring frequency need to be increased.

[0082] In this embodiment, based on the above-described process of performing a second pretreatment on cassia seed raw materials, the quality data of the cassia seed raw materials after the second pretreatment and the processing data during the second pretreatment process are obtained. The quality index of the second pretreatment of cassia seeds is then analyzed. The quality data of the cassia seed raw materials after the second pretreatment and the processing data during the second pretreatment process are the same as the quality data of the cassia seed raw materials after the first pretreatment and the processing data during the pretreatment process. Therefore, by analyzing the analysis process and method of the cassia seed pretreatment quality index, the quality index of the second pretreatment of cassia seeds can also be obtained. The quality index of the second pretreatment of cassia seeds is then compared with the cassia seed pretreatment quality index threshold preset in the production database.

[0083] If the quality index of the second pretreatment of cassia seeds is greater than or equal to the threshold of the pretreatment quality index of cassia seeds preset in the production database, then the cassia seed raw materials after the second pretreatment will be directly used for cassia seed tea production, and the quality index of the second pretreatment of cassia seeds will be recorded as the quality index of the pretreatment of cassia seeds.

[0084] If the quality index of the secondary pretreatment of cassia seeds is less than the preset threshold of the quality index of cassia seed pretreatment in the production database, an early warning will be issued directly for the cassia seed raw materials.

[0085] It needs to be explained that when the quality index of the second pretreatment of cassia seeds is greater than or equal to the preset threshold of the cassia seed pretreatment quality index in the production database, it means that the cassia seed raw materials after the second pretreatment have met the production requirements in terms of harmful substance content, impurity content ratio, and moisture content ratio. Therefore, the quality of the cassia seed raw materials is qualified and can be directly used for the production of cassia seed tea without further processing or inspection. When the quality index of the second pretreatment of cassia seeds is less than the preset threshold of the cassia seed pretreatment quality index in the production database, although a second pretreatment has been performed, the quality of the cassia seed raw materials still does not meet the production requirements. This may be due to a quality problem with the raw materials themselves. In this case, an early warning should be issued to the cassia seed raw materials immediately. The specific warning can be a text message displayed on the operation interface of the production equipment to inform the operator of the current problem. The text content could be: "Warning: The quality of the second pretreatment of cassia seeds is lower than the standard value. Please check and process the cassia seed raw materials immediately."

[0086] Specifically, the analysis process for the quality indicators of cassia seed tea production is as follows:

[0087] The production data of the cassia seed tea production process specifically includes the frying time, real-time frying temperature and average frying frequency during the production cycle.

[0088] It should be explained that the above production cycle refers to the time required from the start of frying the cassia seed raw materials to the completion of cassia seed tea production. This time includes various stages such as frying and cooling of the raw materials. The frying time is measured by a timer. The time elapsed from the start of the frying equipment until the frying is completed and the equipment is turned off is the frying time. The real-time frying temperature is measured by a temperature sensor embedded in the frying equipment. The average frying frequency is calculated by the automated frying equipment recording the number of times and the time of frying during the frying process. This frequency is usually expressed as the number of times frying is performed per minute.

[0089] The environmental data specifically includes the real-time humidity and average microbial content of the area where the cassia seed tea is produced during the production cycle.

[0090] It should be explained that the real-time humidity of the area where the cassia seed tea is produced during the production cycle is measured by a humidity sensor placed in the cassia seed tea production area; the average microbial content can be detected by high-throughput sequencing.

[0091] The real-time humidity of the area where the cassia seed tea is produced during the production cycle is compared with the preset reference humidity in the production database to obtain the real-time humidity deviation value of the area where the cassia seed tea is produced during the production cycle.

[0092] The difference between the real-time roasting temperature of cassia seed tea during the production cycle and the preset roasting reference temperature in the production database is processed to obtain the real-time roasting temperature deviation value of cassia seed tea during the production cycle.

[0093] The production quality indicators of cassia seed tea are obtained by comprehensively analyzing the frying time, real-time frying temperature deviation, average frying frequency, real-time humidity deviation, average microbial content, and cassia seed pretreatment quality index of the production cycle.

[0094] In this embodiment, during the production process of the cassia seed tea, there are interrelationships among the frying time, real-time frying temperature deviation, average frying frequency, real-time humidity deviation in the production area, average microbial content, and cassia seed pretreatment quality index. Higher frying temperatures can shorten the frying time, but excessively high temperatures may cause the cassia seeds to scorch, affecting quality. Frequent frying ensures uniform heating of the cassia seeds and prevents local overheating or scorching, which may require a longer frying time to complete the frying process. However, excessively high frying frequency may also lead to energy loss and reduced frying efficiency. High temperatures during the frying process can kill or inhibit the growth of microorganisms, thereby reducing the average microbial content. High humidity environments are conducive to the growth and reproduction of microorganisms, which may increase the average microbial content. Humidity also affects the dryness and shelf life of cassia seed tea. Excessively high humidity may cause the cassia seed tea to become damp and deteriorate, affecting quality. Cassia seeds with better pretreatment quality are more likely to reach the ideal frying degree during the frying process, thus maintaining better quality. Conversely, cassia seeds with poor pretreatment quality may require a longer frying time or a higher frying temperature to achieve the same frying effect.

[0095] The specific analytical method for the quality indicators of cassia seed tea production is as follows:

[0096] ;

[0097] In the formula, The quality indicators for cassia seed tea production are given by , where e is a natural constant. For the cooking time, The preset reference cooking time for the production database To achieve an average stir-frying frequency, The preset stir-frying reference frequency for the production database. This represents the average content of microorganisms. This is the starting point of the production cycle. This is the end point of the production cycle. For any point in time within the production cycle, , Within the production cycle of the region where cassia seed tea is produced Real-time humidity deviation at a given time point. The preset humidity tolerance value for the production database. Within the production cycle of the region where cassia seed tea is produced Real-time cooking temperature deviation at a given time point. The preset temperature tolerance value for the production database. The quality index of cassia seed pretreatment. The production impact index corresponding to the unit value of microbial content preset for the production database. The production impact index corresponding to the unit value of the Cassia seed preprocessing quality index preset for the production database.

[0098] It should be explained that the above-mentioned roasting time refers to the total time required from the time the cassia seeds are placed in the roasting equipment until they are roasted and removed; the preset reference roasting time in the production database is a reference roasting time value preset in the database based on past production experience; the average turning frequency refers to the average number of turning actions during the roasting process; the preset reference turning frequency in the production database is a reference value for turning frequency preset in the database based on past production experience; the average microbial content refers to the average number of microorganisms obtained after microbial testing of the area where the cassia seed tea is produced during the production cycle; any point in time within the production cycle refers to any moment between the start and end of production; the real-time humidity deviation value refers to the difference between the real-time humidity and the reference humidity in the area where the cassia seed tea is produced during the production cycle; the preset allowable humidity deviation value refers to the allowable fluctuation value of the ambient humidity relative to the ideal humidity value during the production process; the preset allowable temperature deviation value in the production database refers to the allowable fluctuation value of the ambient temperature relative to the ideal temperature value during the production process; the real-time roasting temperature deviation value refers to the difference between the real-time roasting temperature and the roasting temperature of the cassia seed tea during the production cycle. The difference between reference temperatures; the cassia seed pretreatment quality index is a comprehensive index used to evaluate the pretreatment results by comprehensively analyzing parameters such as the average content of harmful substances, the ratio of impurities, the ratio of moisture content, the washing time of the cassia seed raw materials during the pretreatment cycle, the difference in real-time washing and stirring frequency, and the real-time water temperature difference. In this embodiment, in the specific method for analyzing the production quality indicators of cassia seed tea, nonlinear analysis is selected to analyze the frying time, real-time frying temperature deviation, average frying frequency, real-time humidity deviation, and average microbial content. Nonlinear analysis is highly sensitive to changes in input values; small changes in input values ​​may lead to significant changes in output values. In the production process of cassia seed tea, it helps to accurately capture the small fluctuations of each parameter, thereby controlling the production conditions more precisely and reflecting the complex relationships between parameters. Similarly, the results of using nonlinear analysis to analyze and calculate the cassia seed pretreatment quality index are usually more intuitive and easier to understand, directly reflecting the quality level of the cassia seed pretreatment stage, and have the effect of smoothing data fluctuations, reducing the impact of individual outliers on the overall evaluation results.

[0099] It should be explained that the production impact index corresponding to the unit value of microbial content in the aforementioned production database represents the degree of influence of the unit value of microbial content on the production quality indicators of cassia seed tea. The production database stores the correspondence between the unit value of microbial content and its corresponding production impact index. For example, if the unit value of microbial content is input into the production database, the production database can match the production impact index corresponding to the unit value of microbial content. Similarly, the production impact index corresponding to the unit value of cassia seed pretreatment quality index in the production database represents the degree of influence of the unit value of cassia seed pretreatment quality index on the production quality indicators of cassia seed tea. The production database stores the correspondence between the unit value of cassia seed pretreatment quality index and its corresponding production impact index. For example, if the unit value of cassia seed pretreatment quality index is input into the production database, the production database can match the production impact index corresponding to the unit value of cassia seed pretreatment quality index.

[0100] In this embodiment, a large or small deviation from the preset reference roasting time will cause changes in the quality characteristics of cassia seed tea, such as taste, color, and aroma. If the roasting time is too short, the cassia seeds may not be sufficiently heated, resulting in insufficient aroma and a harsh taste; if the roasting time is too long, the cassia seeds may be over-caramelized, producing a bitter taste and even destroying their nutritional components. A large or small average stirring frequency, deviating significantly from the preset reference stirring frequency, will affect the uniformity of heating during the roasting process. Too fast a stirring frequency may cause the surface of the cassia seeds to overheat while the interior is not sufficiently heated; too slow a stirring frequency may cause localized overheating and scorching. A larger average microbial content will increase the safety risks of consuming cassia seed tea. Real-time humidity deviation... Significant differences in humidity levels, even exceeding the preset allowable deviation, can make it difficult for cassia seed tea to dry during the roasting process, increasing the risk of mold growth during subsequent storage. Similarly, large deviations in real-time roasting temperature, exceeding the preset allowable deviation, can cause the tea leaves to darken or even burn, affecting their color and appearance. Excessive temperature deviations can also lead to inconsistent tea leaf shapes, resulting in fragments and breakage, thus reducing the overall quality of the tea. A low cassia seed pretreatment quality index directly impacts the uniformity of heating and the final quality of the cassia seed tea during roasting. Therefore, a detailed analysis of the parameters in the cassia seed tea production quality indicators allows for the timely identification of problems in the production process and the implementation of corresponding improvement measures, thereby enhancing the overall quality of cassia seed tea.

[0101] Specifically, the process of determining whether to control the production process of cassia seed tea based on the production comparison results is as follows:

[0102] If the production quality index of cassia seed tea is greater than or equal to the preset production quality index limit value of cassia seed tea in the production database, the production comparison result will be recorded as the first production comparison result.

[0103] If the production quality indicators of cassia seed tea are less than the preset production quality indicator limits of cassia seed tea in the production database, the production comparison result will be recorded as the second production comparison result.

[0104] If the production comparison result is the second production comparison result, then the production process of cassia seed tea needs to be controlled.

[0105] In this embodiment, the production quality indicators of cassia seed tea are compared with the preset production quality indicator thresholds of cassia seed tea in the production database. When the production quality indicators of cassia seed tea are greater than or equal to the preset production quality indicator thresholds of cassia seed tea in the production database, it means that the production quality of cassia seed tea has reached or exceeded the preset production quality standards. This indicates that the production process is well controlled, the raw material quality is good, and the production process parameters are set reasonably, ensuring the stability and consistency of the product. At this time, the production comparison result is recorded as the first production comparison result, indicating that the production quality meets the standards or is excellent. When the production quality indicators of cassia seed tea are less than the preset production quality indicator thresholds of cassia seed tea in the production database, it means that the quality of the currently produced cassia seed tea has not reached the preset production quality standards. This may be due to poor raw material quality, improper setting of production process parameters, or lax control of the production process. This situation requires attention, identification of the problem, and corresponding measures to improve it. At this time, the production comparison result is recorded as the second production comparison result, indicating that the production quality does not meet the standards. If the production comparison result is the second production comparison result, the production process of cassia seed tea needs to be controlled.

[0106] The production process of cassia seed tea is controlled, and the specific control process is as follows:

[0107] When the production comparison result is the second production comparison result, it is necessary to increase the frying temperature, increase the frying frequency, and reduce the frying time.

[0108] In this embodiment, when the production comparison result is the second production comparison result (i.e., the production quality does not meet the standard), control measures such as increasing the frying temperature, increasing the frying frequency, and reducing the frying time are taken. These decisions are based on a comprehensive analysis of the production quality indicators. Before production, although parameters such as frying temperature, frying frequency, and frying time can be set based on experience or preset standards, these parameters may be affected by various factors, such as raw material quality, equipment performance, and environmental conditions. Directly controlling according to preset parameters may not accurately reflect changes in the actual production process, leading to unstable production quality. This is addressed by analyzing the cassia seed tea after production. Product quality indicators can more accurately assess the actual quality level of a product. When production quality fails to meet standards, parameters such as frying temperature, frying frequency, and frying time can be adjusted in a targeted manner based on the specific quality indicators to improve product quality. The comprehensive formula for production quality indicators usually considers multiple quality factors, comprehensively reflecting the overall quality level of the product. By comprehensively analyzing these indicators, it is possible to more accurately determine whether the product quality meets the standards and what control measures need to be taken to improve quality. Based on the analysis results of the comprehensive formula for production quality indicators, it is clear which parameters need to be adjusted, as well as the direction and extent of the adjustment, thereby improving production efficiency and product quality.

[0109] Furthermore, the specific analysis process for the cassia seed tea packaging quality index is as follows:

[0110] The frying time of cassia seed tea during the production cycle is matched with the moisture content threshold of cassia seed tea corresponding to each frying time interval preset in the production database to obtain the preset moisture content threshold of cassia seed tea.

[0111] In this embodiment, the roasting time of cassia seed tea during the production cycle is matched with the moisture content threshold of cassia seed tea corresponding to each roasting time interval preset in the production database. The specific matching process is as follows:

[0112] The frying time of cassia seed tea during the production cycle is matched with the moisture content threshold of cassia seed tea corresponding to each frying time interval preset in the production database, thereby obtaining the preset moisture content threshold of cassia seed tea.

[0113] In one specific embodiment, the roasting time of cassia seed tea during the production cycle is 10 minutes, and the roasting time intervals stored in the production database are [10, 20). Therefore, the moisture content threshold of cassia seed tea corresponding to the roasting time interval [10, 20) is 8%.

[0114] The average moisture content of cassia seed tea during the packaging period is obtained and compared with the preset moisture content threshold of cassia seed tea in the production database to obtain the moisture content ratio of cassia seed tea during the packaging period.

[0115] It should be explained that the average moisture content of the cassia seed tea during the packaging cycle is obtained by periodically measuring the moisture content of the cassia seed tea bags and averaging these measurements over the entire packaging cycle (from the start to the end of packaging). Specific measurement methods may include using professional moisture measuring instruments (such as microwave moisture meters) to test the moisture content of the cassia seed tea bags. To ensure the representativeness of the data, multiple measurements should be taken at different points in the packaging cycle, and these measurements should be summed and divided by the number of measurements to obtain the average moisture content. In this embodiment, the packaging cycle refers to the time period from the start to the end of packaging the cassia seed tea. The specific length of this time period may vary depending on factors such as product type and production process. In practice, the length of the packaging cycle can be determined by recording the start and end times of packaging.

[0116] To obtain the average content of harmful substances in cassia seed tea during its packaging cycle.

[0117] It should be explained that the above-mentioned content of harmful substances was obtained by detecting the raw materials of cassia seeds using gas chromatography (GC) to detect whether the raw materials of cassia seeds contain harmful substances and their content, and by performing average analysis on the content of various harmful substances detected, thereby obtaining the average content of harmful substances.

[0118] The environmental data during the packaging process specifically includes the real-time humidity and average electrostatic voltage of the environment in which the cassia seed tea is packaged.

[0119] It should be explained that the real-time humidity mentioned above is obtained through humidity sensors in the packaging workshop; the electrostatic voltage is measured using a specialized electrostatic voltage tester. During the packaging process, the electrostatic voltage of the cassia seed tea bags or packaging materials is tested at different time points, and these test values ​​are averaged to obtain the average electrostatic voltage.

[0120] The packaging quality data specifically includes the average sealing strength, average gas leakage rate, and average weight of the cassia seed tea bags during the packaging period.

[0121] It should be explained that the aforementioned average sealing strength is usually obtained by testing the sealing strength of randomly selected cassia seed tea bags using a sealing strength tester. During the test, the probe of the tester is placed at the seal of the tea bag, and gradually increasing pressure is applied until the seal breaks. The sealing strength value of each tea bag is recorded, and these values ​​are averaged to obtain the average sealing strength. The average gas leakage rate is obtained by using a specialized gas leakage tester connected to the tea bag packaging to monitor the loss of gas inside the packaging. The gas leakage rate is obtained by calculating the reduction in the gas content inside the packaging during the packaging period, and the test results of multiple tea bags are averaged to obtain the average leakage rate. A high-precision electronic scale is used to weigh each cassia seed tea bag. During the packaging period, the weight data of the cassia seed tea bags is continuously collected, and all the collected weight data of the cassia seed tea bags are summarized and statistically analyzed to calculate the average weight.

[0122] The packaging quality index of cassia seed tea is obtained by comprehensively analyzing the moisture content ratio, average content of harmful substances, real-time humidity, average static voltage, average sealing strength, average gas leakage rate, and average weight of the cassia seed tea bags during the packaging period.

[0123] In this embodiment, there are complex interrelationships among the moisture content ratio, average content of harmful substances, real-time humidity of the environment surrounding the cassia seed tea during the packaging period, average electrostatic voltage, average sealing strength of the cassia seed tea bags, average gas leakage rate, and average weight. Excessively high moisture content may lead to tea deterioration and mold growth, increasing the average content of harmful substances; conversely, excessively low moisture content may cause the tea to become too dry, losing its aroma and flavor. Therefore, the moisture content ratio is one of the important indicators for measuring the quality stability of cassia seed tea. Real-time humidity has a direct impact on the moisture content of cassia seed tea; excessively high humidity may cause the tea to absorb moisture. The packaging of cassia seed tea can absorb moisture from the environment, increasing its moisture content. However, excessively low humidity can cause tea leaves to lose water and reduce their moisture content. High static voltage can damage the packaging materials, such as puncturing the packaging film, leading to an increased gas leakage rate. At the same time, static electricity can also attract dust and microorganisms from the air, affecting the hygienic quality of the tea. Insufficient sealing strength may cause the packaging to break during transportation and storage, exposing the tea to adverse environments and increasing the risk of changes in moisture content. Excessive gas leakage rate can cause changes in the concentration of gases such as oxygen and carbon dioxide inside the packaging, affecting the oxidation level and taste of the tea. In addition, leakage may also allow microorganisms to invade, affecting the hygienic quality of the tea.

[0124] The specific analysis method for the cassia seed tea packaging quality index is as follows:

[0125] ;

[0126] In the formula, The quality index for cassia seed tea packaging is given by 'e', ​​where 'e' is a natural constant. This is the starting point of the packaging cycle. This is the end point of the packaging cycle. Any point in time within the packaging cycle. , Within the packaging cycle of cassia seed tea Real-time humidity of the environment at a given time point. The reference humidity preset for the production database, The average electrostatic voltage, The electrostatic reference voltage preset for the production database, For average sealing strength, The sealing reference strength is preset for the production database. The average gas leakage rate, The packaging impact index corresponding to the unit value of the average gas leakage rate preset for the production database. The moisture content of cassia seed tea during its packaging period. The packaging impact index corresponding to the unit value of moisture content is preset for the production database. Average weight The reference weight preset for the production database. This represents the average content of harmful substances. Packaging impact indicators corresponding to the unit values ​​of hazardous substance content preset for the production database.

[0127] It should be explained that "any point in time within the packaging cycle" refers to any moment within the entire time period from the start to the end of packaging. This point in time can be the start time, end time, or other time points of the packaging cycle, used to record or monitor changes in various parameters during the packaging process. Real-time humidity refers to the humidity value of the packaging workshop or storage environment during the packaging cycle. The preset reference humidity is a humidity value set in advance according to the needs of cassia seed tea preservation and quality control. Average electrostatic voltage refers to the average value of the electrostatic voltage carried by the packaging materials during the packaging cycle. The preset electrostatic reference voltage is a preset electrostatic voltage value based on the characteristics of the packaging materials and cassia seed tea. The full value; average sealing strength refers to the average strength of the sealing position; preset sealing reference strength refers to a minimum sealing strength set in advance based on the characteristics of the packaging material and cassia seed tea; average gas leakage rate refers to the average rate at which gas inside the packaging leaks to the outside through the packaging material during the packaging cycle; moisture content ratio refers to the ratio of the average moisture content of cassia seed tea during the packaging cycle to the preset moisture content threshold in the production database; average weight refers to the average weight of the cassia seed tea bag; preset reference weight refers to the weight value of a tea bag set in advance based on packaging requirements and the characteristics of cassia seed tea; average content of harmful substances refers to the average content of various harmful substances in cassia seed tea.

[0128] It should be explained that the packaging impact index corresponding to the unit value of the average gas leakage rate preset in the production database represents the degree of influence of the unit value of the average gas leakage rate on the packaging quality index of cassia seed tea. The production database stores the correspondence between the unit value of the average gas leakage rate and its corresponding packaging impact index. For example, by inputting the unit value of the average gas leakage rate into the production database, the production database can match the packaging impact index corresponding to the unit value of the average gas leakage rate. Similarly, the packaging impact index corresponding to the unit value of the moisture content ratio preset in the production database represents the degree of influence of the unit value of the moisture content ratio on the packaging quality index of cassia seed tea. The production database stores the correspondence between the unit value of the moisture content ratio and its corresponding packaging impact index. For example, by inputting the unit value of the moisture content ratio into the production database, the production database can match the packaging impact index corresponding to the unit value of the moisture content ratio. Similarly, the packaging impact index corresponding to the unit value of the harmful substance content preset in the production database represents the degree of influence of the unit value of the harmful substance content on the packaging quality index of cassia seed tea. The production database stores the correspondence between the unit value of the harmful substance content and its corresponding packaging impact index. For example, by inputting the unit value of the harmful substance content into the production database, the production database can match the packaging impact index corresponding to the unit value of the harmful substance content.

[0129] In this embodiment, excessively high or low real-time humidity (i.e., a significant deviation from the preset reference humidity) can cause the tea to mold and spoil, while excessively low humidity can cause the tea to lose its original aroma. Similarly, excessively high or low average electrostatic voltage (i.e., a significant deviation from the preset electrostatic reference voltage) can cause the tea to absorb dust, hair, and other impurities from the air, affecting its cleanliness. Excessively high or low average sealing strength (i.e., a significant deviation from the preset sealing reference strength) can also cause the packaging to crack or leak during transportation and storage, leading to moisture absorption and oxidation of the tea, while excessively high sealing strength can make it difficult to open the packaging when using the cassia seed tea later, affecting the user experience. A high average gas leakage rate can also cause oxygen to enter the packaging, accelerating the oxidation process of the tea and causing it to lose its original color and aroma. Meanwhile, gas leaks can also cause changes in humidity inside the packaging, further reducing the quality index of cassia seed tea packaging. A large or small average weight, meaning a significant deviation from the preset reference weight, can lead to insufficient internal space if the tea leaves are too heavy, causing them to be packed too tightly and increasing friction and compression, potentially resulting in breakage or loss of aroma. Conversely, too little tea weight can create excessive space, leading to unnecessary shaking during transportation or storage, also affecting quality. A high average content of harmful substances can threaten the safety of the tea, further reducing the quality index of cassia seed tea packaging. Therefore, detailed analysis of each parameter in the cassia seed tea packaging quality index can help identify and improve problems in the production process, thereby enhancing product quality.

[0130] Specifically, the final determination of whether the packaging process of cassia seed tea needs to be controlled based on the comparison results of packaging quality is as follows:

[0131] If the packaging quality index of cassia seed tea is greater than or equal to the preset threshold of the packaging quality index of cassia seed tea in the production database, then the packaging quality comparison result will be recorded as the first comparison result of the packaging.

[0132] If the packaging quality index of cassia seed tea is less than the preset threshold of the packaging quality index of cassia seed tea in the production database, the packaging quality comparison result will be recorded as the second packaging comparison result.

[0133] If the packaging quality comparison result is the second best result, then the packaging process of cassia seed tea needs to be controlled.

[0134] In this embodiment, the packaging quality index of cassia seed tea is compared with the preset threshold for cassia seed tea packaging quality index in the production database. If the packaging quality index is greater than or equal to the preset threshold, it means that the packaging quality of the cassia seed tea has reached or exceeded the expected standard, indicating that the packaging process is well controlled and the tea maintains stable quality throughout the packaging period. In this case, the packaging quality comparison result can be recorded as "first packaging comparison result," usually indicating normal or qualified. If the packaging quality index is less than the preset threshold, it means that the packaging quality of the cassia seed tea has not reached the expected standard, and there may be problems such as packaging material issues, insufficient sealing strength, excessive gas leakage rate, or unstable moisture content. At this point, the packaging quality comparison result needs to be recorded as "Packaging Second Comparison Result," which usually indicates non-compliance or abnormality. If the packaging quality comparison result is "Packaging Second Comparison Result," then the packaging process of cassia seed tea needs to be controlled. Specifically, controlling the packaging process of cassia seed tea can involve checking the quality and suitability of the packaging materials to ensure that the materials meet the packaging requirements and will not have a negative impact on the quality of the tea; adjusting the parameters of the sealing equipment, such as temperature, pressure, and time, to ensure that the sealing strength meets the requirements; regularly inspecting and testing the sealing position to promptly identify and repair potential problems; and strengthening humidity and static electricity control measures in the packaging workshop or storage environment to ensure that environmental parameters are within a suitable range.

[0135] Reference Figure 2 As shown, the second aspect of the present invention provides a production control system for cassia seed tea, comprising: a cassia seed raw material pretreatment module, a cassia seed tea production module, a cassia seed tea detection module, and a production database.

[0136] The cassia seed raw material pretreatment module is connected to the cassia seed tea production module, the cassia seed tea production module is connected to the cassia seed tea testing module, and the cassia seed raw material pretreatment module, the cassia seed tea production module, and the cassia seed tea testing module are all connected to the production database.

[0137] The cassia seed raw material pretreatment module is used to perform a first pretreatment on the cassia seed raw material, obtain the quality data of the cassia seed raw material after the first pretreatment and the processing data during the pretreatment process, comprehensively analyze to obtain the cassia seed pretreatment quality index, and compare it with the cassia seed pretreatment quality index threshold preset in the production database to obtain the pretreatment comparison result. Based on the pretreatment comparison result, it is determined whether the pretreatment process of the cassia seed raw material needs to be controlled.

[0138] The cassia seed tea production module is used to produce cassia seed tea from pre-treated cassia seed raw materials, acquire production data and environmental data during the production process, and conduct comprehensive analysis with the cassia seed pre-treatment quality index to obtain cassia seed tea production quality indicators. These indicators are then compared with the preset cassia seed tea production quality indicator definition values ​​in the production database to obtain production comparison results. Based on the production comparison results, it is determined whether the production process of cassia seed tea needs to be controlled.

[0139] The cassia seed tea detection module is used to mark the produced cassia seed tea as packageable cassia seed tea and perform packaging operations. The packaged cassia seed tea is marked as a cassia seed tea bag. Through the packaging process of packageable cassia seed tea, environmental data and packaging quality data during the packaging process are obtained.
