[0002] As an important natural resource, animal fats are widely used in food processing, cosmetics manufacturing, biofuels, pharmaceuticals and other fields. However, raw animal fats contain a lot of impurities, which affect their quality and application value. Therefore, they need to be refined in multiple process stages.

[0003] During the refining process, different stages of the process require different heating temperatures and durations. Therefore, traditional animal fat refining usually relies on the control of temperature and time to achieve the switching of different process stages. However, this method is relatively rigid and not applicable to the quality of animal fats in the refining process. It is impossible to quickly and accurately switch between different process stages according to the quality of animal fats, which affects the efficiency of animal fat refining. Summary of the invention

[0004] In view of the above problems, the present application provides an efficient refining control method and system for animal fats and oils, the main purpose of which is to quickly and accurately dynamically switch different process stages according to the quality of the animal fats and oils, so as to improve the refining efficiency of the animal fats and oils.

[0005] In order to solve the above technical problems, this application proposes the following solutions:

[0006] In a first aspect, the present application provides a method for efficiently controlling the refining of animal fats and oils, which is applied to oil refining equipment, and the method comprises:

[0008] Determining whether the animal fat meets the process switching standard corresponding to the target process stage according to the state parameter, wherein the process switching standard is set according to the quality requirements corresponding to different process stages;

[0009] If so, the oil refining equipment is controlled to execute the next process stage corresponding to the target process stage.

[0013] A switching control unit is used to generate a process switching instruction to control the oil refining equipment to execute the next process stage corresponding to the target process stage.

[0014] In order to achieve the above-mentioned purpose, according to the third aspect of the present application, a storage medium is provided, which includes a stored program, wherein when the program is running, the device where the storage medium is located is controlled to execute the efficient refining control method of animal fats and oils of the above-mentioned first aspect.

[0015] In order to achieve the above-mentioned purpose, according to the fourth aspect of the present application, a processor is provided, wherein the processor is used to run a program, wherein when the program is running, the efficient refining control method of animal fats and oils of the first aspect mentioned above is executed.

[0023] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0024] At present, traditional animal fat refining usually relies on the control of temperature and time to switch between different process stages. For example, the temperature of the preheating / melting stage is generally between 40 and 60 degrees, and the duration depends on the type and initial state of the fat, which may range from a few minutes to a few hours. The temperature of the degumming / dehydration stage is about 70 to 90 degrees, and the duration may take several hours. During this period, phosphates or diatomaceous earth may need to be added as degumming agents, etc. In addition, there are deacidification / neutralization stages, decolorization / bleaching stages, and deodorization stages, and the corresponding temperatures and times are different. However, this method is relatively rigid and is not applicable to the quality of animal fats in the refining process. It is impossible to quickly and accurately switch between different process stages according to the quality of animal fats, which affects the efficiency of animal fat refining.

[0025] To this end, the embodiment of the present application provides an efficient refining control method for animal fats, through which different process stages can be quickly and accurately switched dynamically according to the quality of the animal fats, thereby improving the refining efficiency of the animal fats. The specific execution steps are as follows: Figure 1 As shown, it is applied to oil refining equipment, including 101-103.

[0026] 101. When the oil refining equipment executes the target process stage, the state parameters corresponding to the animal fat are obtained.

[0027] It should be noted that, in this embodiment, the execution subject is the oil refining equipment. The target process stage can be any stage in the animal fat refining process, including but not limited to: preheating / melting stage, degumming / dehydration stage, deacidification / neutralization stage, decolorization / bleaching stage and deodorization stage.

[0028] Among them, the state parameters are used to characterize parameters related to the quality of oils and fats. Including but not limited to: color, transparency, impurity distribution, acid value and peroxide value, etc. This can be achieved by installing corresponding high-precision sensors at key positions of the oil refining equipment, such as installing infrared spectrum sensors to measure the color, transparency and impurity distribution of oils and fats, and installing oil composition analysis sensors to quickly measure the acid value and peroxide value of oils and fats. Specifically, the Internet of Things technology can be used to realize the real-time transmission of data by the above-mentioned high-precision sensors to the controller of the oil refining equipment, so that the controller integrates the real-time transmission of data by each high-precision sensor to execute step 102. In addition, in order to facilitate the staff to view and analyze the state changes of animal fats and fats in real time, a corresponding display device can also be installed, and a unified monitoring interface based on all the integrated data can be formed and displayed in the display device.

[0029] 102. Determine whether the animal fat meets the process switching standard corresponding to the target process stage based on the state parameters.

[0030] Among them, the process switching standard is set according to the quality requirements corresponding to different process stages. The quality requirements refer to a series of specific quality indicators or standards that animal fats must meet at the end of each process stage during the animal fat refining process. Combined with the description of the state parameters in the above step 101, the state parameters that correspond to or correspond to different process stages at the same time can be divided into corresponding state dimensions, such as color dimension, transparency dimension or impurity distribution dimension, and further set parameter targets corresponding to different state dimensions, and the parameter targets corresponding to different state dimensions in different process stages are used as the basis for judging the process switching standard.

[0031] It should be noted that for the parameter targets corresponding to different state dimensions, the parameter values ​​corresponding to different state dimensions at the end of different process stages can be obtained based on the oil refining theory and practical experience, or the thresholds for switching between each stage can be reached through the analysis of machine learning models such as pre-set decision trees or neural networks, and the parameter value or the threshold can be set as the parameter target. For example, the degumming stage requires that the impurity percentage corresponding to the impurity distribution is lower than a certain impurity percentage threshold, and the bleaching stage requires that the transmittance corresponding to the transparency exceeds a certain transmittance threshold, and the percentage threshold and transmittance threshold can be directly used as parameter targets. In order to further improve the accuracy of process switching based on quality-related state parameters, a safety margin value can be superimposed on the corresponding thresholds of different state dimensions according to quality control requirements. Taking the above-mentioned impurity percentage as an example, if the impurity percentage threshold is 30%, the safety margin value can be set to -3%, then 27% can be used as the final parameter target to further improve the accuracy of process switching based on quality-related state parameters. By comparing the parameter targets and state parameters of different state dimensions under the above-mentioned different process stages, it is possible to determine whether the animal fat meets the process switching standard corresponding to the target process stage. If so, step 103 is executed. If not, the execution time of the target process stage can be counted, and it can be compared with the preset time to determine whether to alarm, so as to prompt the staff to intervene to adjust the working parameters of the refining equipment. Stage optimization rules such as automatically fine-tuning the working parameters within a reasonable range can also be set to optimize the target process stage, and the optimized target process stage is executed. This embodiment does not limit this.

[0032] In addition, since there may be many state dimensions corresponding to different process stages, the main dimensions or secondary dimensions corresponding to different process stages can be further divided according to the specific refining purpose or product standards, or the main dimensions or secondary dimensions common to all process stages can be used for comprehensive judgment to ensure the accuracy and comprehensiveness of the judgment. For example, taking color, transparency, impurity distribution, acid value and peroxide value as examples, the acid value directly reflects the content of free fatty acids in oils and fats, and is an important indicator for measuring the freshness and rancidity of oils and fats. The peroxide value is an indicator for measuring the degree of oxidation of oils and fats, which is directly related to the stability and safety of oils and fats. Therefore, acid value and peroxide value can be used as the main dimensions. Color, transparency and impurity distribution are more related to the appearance of oils and fats. Although they have an impact on market acceptance and attractiveness, they have less impact on the intrinsic quality of oils and fats than acid value and peroxide value. Therefore, acid value and peroxide value can be used as secondary dimensions.

[0033] 103. Control the oil refining equipment to execute the next process stage corresponding to the target process stage.

[0034] In this embodiment, since the multiple process stages of animal fat refining are required to be executed in a certain order, that is, different process stages have a sequential relationship, the sequential relationship can be used to determine the next process stage corresponding to the target process stage, thereby controlling the refining equipment to automatically execute the next process stage, so as to achieve accurate and rapid dynamic switching of process stages.

[0035] Based on the above Figure 1 It can be seen from the implementation method that the efficient refining control method of animal fats provided by the present application is that when efficient refining control of animal fats is required, first, when the oil refining equipment executes the target process stage, the state parameters corresponding to the animal fats are obtained, and the state parameters are used to characterize the parameters related to the quality of the fats. Then, the animal fats are judged according to the state parameters whether they meet the process switching standards corresponding to the target process stage. The process switching standards are set according to the quality requirements corresponding to different process stages. Finally, if yes, the oil refining equipment is controlled to execute the next process stage corresponding to the target process stage. Through the technical solution provided by the present application, the parameters related to the quality of the fats are used as state parameters to judge whether the animal fats meet the process switching standards, and automatically switch from the current target process stage to the next process stage when they meet the standards. This can avoid the over-processing or under-processing caused by the curing control refining process according to temperature and time in the traditional technology, and realize the fast and accurate dynamic switching of different process stages according to the quality of the animal fats, thereby effectively improving the efficiency of animal fat refining, and being able to more accurately control the quality of the fats and oils, and ensure the quality of the animal fats and oils.

[0036] Further, the preferred embodiment of the present application is in the above Figure 1 Based on this, a detailed description of the process of efficient refining control of animal fats is given. The specific steps are as follows Figure 2 As shown, including 201-109.

[0037] 201. Obtain the process parameters corresponding to different process stages and the equipment parameters of the refining equipment.

[0038] In this step, the different process stages and required process parameters of refining animal fats can be determined in advance by consulting industry standards, historical data or professional literature, wherein different process stages have a sequential relationship. For example, taking the preheating / melting stage, degumming / dehydration stage, deacidification / neutralization stage, decolorization / bleaching stage and deodorization stage as examples, the order is usually preheating / melting stage->degumming / dehydration stage->deacidification / neutralization stage->decolorization / bleaching stage->deodorization stage, and the corresponding process parameters include but are not limited to temperature range, pressure level, reaction time, type and amount of chemical additives, etc. The equipment parameters include hardware performance parameters such as specifications, thermal efficiency, stirring capacity, maximum working pressure, and heating rate of the oil refining equipment. Since the process parameters are equivalent to providing an environmental requirement, and the environmental requirement requires the oil refining equipment to obtain the corresponding working parameter control implementation in combination with its own equipment parameters, therefore, it is necessary to perform step 202 according to the process parameters and equipment parameters.

[0039] 202. Determine the working parameters of the refining equipment in different process stages based on the process parameters and equipment parameters, and establish the corresponding relationship between the working parameters and the process stages.

[0040] In this step, based on the process parameters and equipment parameters, parameter matching can be performed through an algorithm or an expert system to ensure that the process parameters are effectively executed within the capacity of the oil refining equipment. That is, the process parameters are converted into the working parameters of the oil refining equipment itself, such as calculating the corresponding heat demand interval based on the temperature interval in the process parameters, and then combining the heat demand interval and the thermal efficiency of the equipment to obtain the power demand interval. Based on the power demand interval, the execution power corresponding to the process stage can be set. Similarly, other process parameters must also be transformed in a coordinated manner. For example, in the deodorization stage, high temperature and high pressure are required for short-term processing. According to the temperature and pressure control capabilities of the oil refining equipment, the appropriate execution power, execution pressure and execution time can be set to maintain a high temperature environment. By converting in units of process stages, the corresponding working parameters of different process stages can be obtained. In order to maintain this corresponding relationship, a mapping table or model of working parameters and process stages can be created and maintained to clarify the ideal working parameter combination of each process stage, so that the working parameters corresponding to different process stages can be quickly determined through the corresponding relationship. In order to further ensure the rationality and feasibility of the working parameter settings, simulation software or historical data can be used for simulation before actual operation to verify whether the working parameters corresponding to different process stages can achieve the expected refining effect.

[0041] 203. Determine the target operating parameters corresponding to the target process stage by using the corresponding relationship, and control the oil refining equipment to operate the target operating parameters to execute the target process stage.

[0042] Since the correspondence between the process stage and the operating parameters has been constructed in step 202, in this step, by using this correspondence, the target operating parameters corresponding to the target process stage can be quickly and accurately determined, and the execution of the target process stage can be achieved by controlling the refinery equipment to operate the target operating parameters.

[0043] 204. When the oil refining equipment executes the target process stage, the state parameters corresponding to the animal fat are obtained.

[0044] This step is combined with the description of step 101 in the above method, and the same contents will not be repeated here.

[0045] 205. Determine the state dimension corresponding to the process switching standard and the parameter targets corresponding to different state dimensions.

[0046] In this step, the state dimension refers to the dimension related to the quality of the oil, which corresponds to the state parameter in this embodiment. The corresponding state dimension can be divided in combination with the specific parameters included in the state parameter. However, due to the differences in the state dimensions focused on in different process stages, such as the degumming / dehydration stage focuses on impurity distribution and moisture content, the deacidification / neutralization stage focuses on acid value, the decolorization / bleaching stage focuses on color and transparency, and the deodorization stage focuses on peroxide value and odor. Therefore, different state dimensions can be associated with each process stage to ensure that the animal fats and oils in each process stage meet their corresponding quality requirements. After determining the state parameters, specific and quantitative parameter targets can be set for each state dimension based on the professional knowledge or market demand of animal fat refining. For example, the degumming / dehydration stage requires the percentage of impurities to be less than 0.1%, and the decolorization / bleaching stage requires the transmittance to reach more than 90%.

[0047] 206. Compare the state parameters with parameter targets corresponding to different state dimensions respectively to obtain comparison results.

[0048] In this step, since the parameter targets corresponding to different state dimensions have been determined, the state parameters collected in real time are compared one by one with the parameter targets corresponding to different state dimensions. This can be done by directly comparing the numerical values ​​or by processing the data using mathematical models or algorithms, such as calculating deviation values ​​or standardized scores, so as to clarify which state dimensions have met the standards and obtain corresponding comparison results, which are used to characterize the state dimensions that have met the standards.

[0049] 207. Determine whether the animal fat meets the process switching standards based on the comparison results.

[0050] In this step, the judgment process of whether the animal fat meets the process switching standard can be judged by a direct threshold, such as if the number of state dimensions that meet the standard is greater than the preset number threshold, it meets the process switching standard. It can also be judged by a more complex scoring system, such as scoring each state dimension that meets the standard by weight, and switching if the total score meets the standard. This embodiment is not limited to this. Once it is determined that the animal fat meets the process switching standard, it means that the requirements for switching from the target process stage to the next process stage are met at this time, and step 208 is executed at this time. Otherwise, it means that the requirements for switching from the target process stage to the next process stage are not met, and step 209 is executed at this time.

[0051] Furthermore, in order to improve the rationality and accuracy of the judgment of the process switching standard, thereby improving the efficiency of animal fat refining. The specific implementation process of judging whether the animal fat meets the process switching standard according to the comparison result is: detect whether the qualified state dimension in the comparison result contains all the main dimensions; if so, determine that the animal fat meets the process switching standard; if not, when the qualified state dimension contains some main dimensions and the number of dimensions containing secondary dimensions is greater than the preset number threshold, determine that the animal fat meets the process switching standard; when the qualified state dimension does not contain any main dimension, or contains some main dimensions but the number of dimensions containing secondary dimensions is less than or equal to the preset number threshold, determine that the animal fat does not meet the process switching standard.

[0052] It should be noted that in this step, the main dimension and the secondary dimension specifically correspond to different process stages. The main dimension refers to the state dimension that needs to be paid special attention to in each process stage, and the secondary dimension refers to all or part of the state dimensions remaining in all state dimensions except the main dimension. For example, in the degumming / dehydration stage, more attention is paid to impurity distribution and moisture content. Therefore, impurity distribution and moisture content may be defined as main dimensions, while color and transparency can be regarded as secondary dimensions. Since the qualified state dimensions have been clearly defined in the comparison results, it is possible to detect whether the qualified state dimensions in the comparison results contain all the main dimensions corresponding to the target process stage. If so, it means that the process switching standard is met, that is, step 208 needs to be executed. If it is not included, there are two situations. One is that all the main dimensions are not included at all. In this case, it means that the oil quality of the animal fat does not meet the process switching standard at all. Therefore, step 209 needs to be executed at this time. The other is that it contains part of the main dimension, but since the qualified status dimension may also contain secondary dimensions, in order to ensure the efficiency of animal fat refining, in this case, the number of dimensions of the secondary dimension can be further compared with the preset number threshold, which can be set according to the overall number of secondary dimensions and the quality control requirements of each process stage. If it is greater than, it means that although the fat quality of the animal fat at this time has not fully met the standards of all the main dimensions, it is close to the requirements as a whole, and it can be further optimized through subsequent process stages. Therefore, at this time, it can also be considered that the animal fat meets the process switching standards, that is, step 208 needs to be executed. Otherwise, it means that the animal fat does not meet the process switching standards, and step 209 needs to be executed.

[0053] In addition, in order to further improve the efficiency of animal fat refining, as another implementation method in addition to the above implementation method, the state dimensions of different process stages can be integrated to determine the main dimensions and secondary dimensions common to each process stage.

[0054] 208. Control the oil refining equipment to execute the next process stage corresponding to the target process stage.

[0055] This step is combined with the description of step 103 in the above method, and the same content is not repeated here. Combined with the description of the order relationship of each process stage and the corresponding relationship between the process stage and the working parameter in steps 201-203, the specific execution process of controlling the oil refining equipment to execute the next process stage corresponding to the target process stage is: determine the next process stage using the order relationship, and determine the next working parameter corresponding to the next process stage using the corresponding relationship; control the oil refining equipment to operate the next working parameter to execute the next process stage.

[0056] Among them, since the sequence relationship refers to the execution order between different process stages, and the corresponding relationship further determines the working parameters of different process stages. Therefore, through the sequence relationship and the corresponding relationship, the next process stage and the next working parameters corresponding to the next process stage can be determined. After determining the next working parameters, the refinery equipment can be controlled to operate the next working parameters, thereby realizing the execution of the next process stage, that is, completing the fast and accurate dynamic switching of different process stages.

[0057] 209. Optimize the target process stage and control the refinery equipment to execute the optimized target process stage.

[0058] This step is combined with the description of step 102 in the above method, and the same content is not repeated here. Combined with the description of the working parameters in steps 201-203, the specific execution process of optimizing the target process stage and controlling the oil refining equipment to execute the optimized target process stage is: adjusting the target working parameters based on the preset parameter gradient to obtain new target working parameters; controlling the oil refining equipment to operate the new target working parameters to execute the optimized target process stage.

[0059] In this step, since the target operating parameter usually refers to a range, such as the execution power range, the execution pressure range and the execution time range, and the target operating parameter may not reach its upper limit during operation due to the smooth over-demand. Then at this time, in order to improve the efficiency of animal oil refining, the target operating parameter can be adjusted according to the preset preset parameter gradient, and the preset parameter gradient can be customized. For example, the temperature adjustment gradient can be increased by 5 degrees, the pressure can be increased by 5 MPa, etc., to ensure that the amplitude of each adjustment is moderate, which can effectively respond to the state parameter changes without causing overreaction. The new target operating parameter can be obtained through the above adjustment. However, it should be emphasized that the new target operating parameter does not exceed the parameter adjustment range corresponding to the target operating parameter. The parameter adjustment range refers to the upper and lower limits of the parameters corresponding to the target operating parameter, so that the parameter gradient adjustment process always meets the process parameters of the target process stage, ensuring the process effectiveness of each process stage.

[0060] Furthermore, in order to avoid abnormal operation of the oil refining equipment during the execution of the target process stage, affecting the efficiency of animal fat refining and reducing the quality of animal fat, it also includes: obtaining the actual working parameters of the oil refining equipment in the target process stage; judging whether the actual working parameters are always within the range of the target working parameters; if not, determining that the oil refining equipment has a failure operation failure and triggering an emergency alarm operation; if so, judging whether the change trend of the actual working parameters meets the requirements of a smooth transition; if not, determining that the oil refining equipment has a potential operation failure and triggering a minor warning operation.

[0061] Among them, the actual working parameters can be collected according to the preset frequency, and can be customized according to the duration corresponding to different process stages. Since the oil refining equipment is operated according to the target working parameters, the actual working parameters are compared with the target working parameters, and the working parameters can be used to determine whether the oil refining equipment has a failure operation failure in the target process stage. Based on the corresponding relationship between the process parameters and the working parameters, the failure operation failure refers to the failure that the actual process parameters exceed the process parameters corresponding to the target process stage through the actual working parameters, which has an actual adverse effect on the oil quality of the refined animal fats in the target process stage. If it occurs, it means that the oil refining equipment is not operating according to the target working parameters at this time, and it may need to be shut down for inspection and maintenance in time. Therefore, an emergency alarm operation can be triggered, which includes but is not limited to automatically controlling the oil refining equipment to shut down and notifying the staff or informing the staff to manually control the oil refining equipment to shut down. If it does not occur, it means that the oil refining equipment is operating according to the target working parameters at this time.

[0062] However, since the smooth transition of working parameters during the refining process can make the oil quality of animal fats better. Therefore, a smooth transition requirement corresponding to a working parameter can be pre-set, and the smooth transition requirement is used to characterize that the change trend of the working parameter during operation is continuous and stable. Specifically, the threshold value reflecting the change trend of each parameter in the working parameter can be used as a measurement standard, such as a threshold value such as a change rate or a fluctuation range. Specifically, a statistical algorithm such as time series analysis or moving average can be used to evaluate the change trend of the actual operating parameters over time, and the actual value such as the parameter change rate or the fluctuation range can be obtained. The actual value is compared with the corresponding threshold value to determine whether the oil refining equipment has a potential operating failure. This potential operating failure refers to the failure that the actual process parameters are deduced from the actual working parameters and do not exceed the process parameters corresponding to the target process stage, but due to the failure of a smooth transition, it has a potential adverse effect on the oil quality of the animal fats refined in the target process stage. If it occurs, it means that although the actual working parameters are within the range of the target working parameters, they have abnormal fluctuations, and the staff needs to monitor in real time to avoid invalid operating failures. Therefore, a minor warning operation may be triggered at this time, including but not limited to notifying the staff to immediately monitor the oil refining equipment remotely or to arrive at the site to monitor the oil refining equipment within a specified time, etc. By judging the range of actual working parameters and smooth transition, it is possible to avoid abnormal operation of the oil refining equipment during the execution of the target process stage, improve the efficiency of animal fat refining, and ensure the quality of animal fat.

[0063] Furthermore, as a response to the above Figure 1-2The implementation of the method embodiment shown in the figure, the embodiment of the present application provides an efficient refining control system for animal fats, which is used to quickly and accurately dynamically switch different process stages according to the quality of animal fats, thereby improving the efficiency of animal fat refining. The embodiment of this system corresponds to the aforementioned method embodiment. For ease of reading, this embodiment will no longer repeat the details of the aforementioned method embodiment one by one, but it should be clear that the device in this embodiment can correspond to all the contents of the aforementioned method embodiment. Specifically, Figure 3 As shown, the system is applied to oil refining equipment and includes:

[0072] The judgment module 323 is used to judge whether the animal fat meets the process switching standard according to the comparison result.
