Description

Technical Field

[0001] The present application belongs to the field of fresh product processing, and specifically relates to a method for maintaining vitamin C content under pulsed intense light sterilization. Background Art

[0002] In fresh products, especially fresh fruits and vegetables, vitamin C is one of the main nutrients and needs to be preserved to the greatest extent. Vitamin C is sensitive to ambient temperature. If the temperature is high, it is easy to hydrolyze. However, this type of fresh product obviously needs to be sterilized to extend the shelf life. In order to ensure the sterilization effect and increase the vitamin C content, pulsed strong light sterilization technology is currently widely used to achieve the effect. In the current technical solution, uniform pulsed strong light parameters are used for pulsed strong light sterilization. This will lead to differences in the maturity of fresh fruits and vegetables. The uniform parameters will easily make the hydrolysis of vitamin C in fresh fruits and vegetables at some maturity values ​​too high. In addition, this technology is currently a specific processing step, which is difficult to connect with technical processes such as fresh fruit and vegetable sorting, resulting in a complex entire production line and low sterilization efficiency. Therefore, in the current pulsed strong light sterilization technology, there is an unreasonable setting of pulsed strong light sterilization parameters, which makes it difficult to maintain the vitamin C content.

[0003] Therefore, how to effectively maintain the vitamin C content based on the application of pulsed intense light sterilization technology is a technical problem that technical personnel in this field urgently need to solve. Summary of the Invention

Step 5: According to the method used in steps 1 to 4, all the pre-treated objects to be tested are compared with the status data groups corresponding to all the sterilization groups that have been generated. If the deviation between all the status data in the status data group of the pre-treated object to be tested and the similar status data in the status data group corresponding to any sterilization group is not higher than the preset deviation, the pre-treated object to be tested is set to the corresponding sterilization group; otherwise, a new sterilization group is created.

[0008] Optionally, obtaining the real-time number of pre-treated objects in the sterilization group and sorting the sterilization group based on the implemented number includes: obtaining in real time the number of pre-treated objects in all the sterilization groups, and obtaining the growth rate of the number of pre-treated objects; sorting the growth rates to obtain a sorting result of the sterilization group; According to the sorting results of the sterilization groups, the sterilization priorities of the sterilization groups are obtained.

[0009] Optionally, setting the order of the pulsed light parameter groups based on the priority of the sterilization group and the characterization information of the pre-treated objects of the sterilization group includes: Based on the characterization information of the sterilization group pretreatment object, obtaining the pulsed intense light parameter group corresponding to the sterilization group; Based on the sterilization priorities of the sterilization groups, obtaining a ranking of the sterilization groups; According to the order of the sterilization groups, the order of the pulsed intense light parameter groups corresponding to the sterilization groups is set.

[0011] Optionally, the sterilizing process is performed on all pre-treated objects in the sterilization group based on the order of the pulsed intense light parameter groups to obtain sterilized objects, including: Based on the order of the pulsed light parameter groups, the pulsed light parameters are adjusted before the pre-treated objects in the sterilization group enter the sterilization production line; The pre-treated objects in the sterilization group should be evenly laid out when entering the sterilization area to avoid overlapping of the pre-treated objects; The pre-treated objects in the sterilization group are rotated while in the sterilization production line to ensure that the surface of the pre-treated objects can be completely sterilized and the sterilized objects can be obtained.

[0015] 2. Improved sterilization efficiency of sterilized objects. The technical solution of this application realizes the correct sorting of sterilized objects. At the same time, considering that sterilized objects in the same state in fresh fruits and vegetables often have clusters, the priority is determined by recording the real-time number of sterilized objects in the sterilization group. At the same time, based on the priority, the order of pulsed strong light sterilization parameters in the next period of time is directly predicted. After passing the verification, the pulsed strong light parameters are directly adjusted according to the parameter order. This method does not need to recalculate the pulsed strong light parameters based on the characterization information of each sterilization group, so it can fully improve the sterilization efficiency.

[0016] 3. The full-process maintenance of vitamin C content is achieved. In the technical solution of this application, in addition to reasonably setting the pulsed strong light parameters based on the characterization information of the sterilized object to ensure that the vitamin C content can be fully increased during the sterilization process, after the sterilization treatment, it is also subjected to lightless refrigeration treatment. At the same time, based on the feedback adjustment concept, the pulsed strong light parameters used in the pulsed strong light sterilization process of the sterilized object are feedback-adjusted, thereby further achieving the maintenance of vitamin C content. From the overall perspective of the technical solution, the full-process maintenance of vitamin C content is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, in the embodiments of the present application, "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0020] In the current preservation and processing of fresh fruits and vegetables, pulsed strong light technology has been widely used for surface sterilization of fresh fruits and vegetables. However, pulsed strong light has a certain promoting effect on the hydrolysis of vitamin C. In order to ensure that the nutrients of fresh fruits and vegetables are maintained, it is necessary to reasonably set and apply the pulsed strong light parameters. In the existing technology, fixed values ​​are usually used for the pulsed strong light parameters of the sterilized objects. This results in the pulsed strong light parameters possibly not being able to adapt to the state of the sterilized objects themselves, resulting in excessive light intensity, excessive hydrolysis of vitamin C, and difficulty in maintaining the vitamin C content. In addition, even if the pulsed strong light parameters can be adjusted, the pulsed strong light parameters are adjusted in real time based on the characteristics of the sterilized objects, which results in low operating efficiency of the entire system and difficulty in achieving high-efficiency adjustment of the pulsed strong light parameters. This leads to a surge in resource consumption of the entire sterilization system, which prolongs the sterilization process time. During pulsed strong light sterilization, the sterilized objects will be affected by other parameters, resulting in a decrease in vitamin C content.

[0021] In order to solve the problems existing in the prior art, the present application discloses a method for maintaining vitamin C content under pulsed intense light sterilization, such as Figure 1 As shown in FIG, a flow chart of a method for maintaining vitamin C content under pulsed intense light sterilization provided in an embodiment of the present application is provided, specifically: S110: Pre-treating the object to be sterilized to obtain a pre-treated object.

[0022] S120 , obtaining characterization information of the pretreatment objects, and setting pretreatment objects with the same characterization information into the same sterilization group.

[0023] S130: Obtain the real-time number of pre-treated objects in the sterilization group, and obtain the sterilization priority of the sterilization group based on the implemented number.

[0024] S140 : Setting the order of the pulsed light parameter groups based on the priority of the sterilization groups and the characterization information of the pre-processed objects of the sterilization groups.

[0025] S150. Based on the order of the pulsed intense light parameter groups, sterilize all pre-treated objects in the sterilization group to obtain sterilized objects.

[0026] S160: performing a light-freezing refrigeration treatment on the sterilized object to obtain a refrigerated object.

[0027] S170. Obtain the vitamin C content of the refrigerated object, and adjust the pulsed light parameter group corresponding to the characterization information of the pre-treated object based on the vitamin C content.

[0028] The beneficial effect of all the above steps is that during the pulsed intense light sterilization process, by rationally sorting the sterilized objects and, based on the sorting results, rationally setting the sorting of the pulsed intense light parameter groups, a correspondence between the sorting results and the pulse objects is established to ensure efficient and high-quality pulsed intense light sterilization, while maintaining the vitamin C content during the specific sterilization process.

[0029] The following is a detailed description of the above steps: As described in step S110, the purpose of this step is to pre-treat the sterilized object, thereby laying the foundation for the subsequent pulsed light sterilization work. Specifically: S111. Based on the category of the sterilized object, obtain a cleaning method for the sterilized object.

[0030] The purpose of this step is that different types of sterilized objects obviously need to be cleaned first, but different types of fresh fruits and vegetables require different cleaning methods. Therefore, it is necessary to obtain the cleaning method for the sterilized objects based on the category of the sterilized objects.

[0031] Among them, the appearance of the sterilized object is obtained, or the category information of the sterilized object is directly input to determine the corresponding cleaning method.

[0032] Among them, common cleaning methods include soaking, steam spraying, etc.

[0033] S112. Based on the cleaning method of the sterilized object, remove surface contamination of the object that can be sterilized by pulsed intense light to obtain a sterilized object without contamination.

[0034] The purpose of this step is to clean the sterilized object, thereby effectively removing surface stains of the sterilized object and avoiding insufficient subsequent pulsed light sterilization effect based on this method.

[0035] Wherein, based on the selected cleaning method, the sterilized object is directly cleaned using the cleaning method.

[0036] During the cleaning process, the integrity of the sterilized objects is also checked so that damaged sterilized objects can be removed.

[0037] After cleaning, the sterilized objects may be further inspected to remove any damaged objects or objects that have not been completely cleaned.

[0038] S113 , obtaining the aggregation state of water droplets on the surface of the non-contaminated sterilized object, and removing the water droplets on the surface of the non-contaminated sterilized object by a non-heating method to obtain a pretreated object.

[0039] The purpose of this step is that when using the pulsed strong light sterilization method, if there are water droplets on the surface, it is easy to cause focusing problems. On the one hand, the strong light can easily burn the sterilized object, and on the other hand, this strong light can cause serious hydrolysis of vitamin C in the sterilized object.

[0040] The surface of the sterilized object without any contamination is inspected to determine whether there are any residual water droplets.

[0041] Among them, when it is found that there are aggregated water droplets, they need to be treated, and the process needs to be carried out in a non-heating manner.

[0042] Among them, the sterilized objects that have been processed are converted into pre-treated objects, and the pre-treated objects are transmitted to the next process flow.

[0043] The beneficial effect of step S110 is that, by pre-treating the sterilized object, the surface stains of the sterilized object are removed, and at the same time, the sterilized object is screened in advance to ensure that the sterilized object can meet the requirements of pulsed strong light sterilization treatment, and on the basis of this, the vitamin C content can be maintained under pulsed strong light sterilization.

[0044] The purpose of step S120 is to integrate pre-processed objects with the same characterization information into the same sterilization group in order to ensure work efficiency and maintain the vitamin C content during the pulsed light sterilization process. Then, the order of the pulsed light parameter groups is determined based on the load status of the sterilization group. In other words, the purpose of this step is to achieve batch object screening and reasonable batch sterilization by setting the same or similar pre-processed objects into the same sterilization group. Specifically: S121. Acquire characterization information of the pre-processed object, where the characterization information includes weight, diameter, color, and reflectivity.

[0045] The purpose of this step is to set the characterization information of the pre-processed object. The so-called characterization information can be used to express the freshness, weight, water content, size, etc. of the pre-processed object.

[0046] Among them, for the representation information of the preprocessed object, it is necessary to judge the representation information according to the category of the preprocessed object.

[0047] The characterization information may be set according to the purpose of detection or the experience of technicians. For example, for blueberries, the characterization information may be set according to relevant indicators of the fruit grade and classified.

[0048] Among them, all the characterization information is used, and weight is used to indicate the size of the pre-processed object. However, a possible problem is that although the weight is large, the water content is insufficient. Therefore, the diameter needs to be measured to determine the density. In addition, the color needs to be detected to determine the maturity based on the color, and the moisture content needs to be determined based on the reflectivity.

[0049] S122: Acquire representation information of all the pre-processed objects one by one to obtain status data of the pre-processed objects.

[0050] The purpose of this step is to detect the preprocessed object after determining its characterization information to determine its specific characterization information.

[0051] Among them, all preprocessing objects need to be obtained one by one to achieve comprehensive acquisition of the representation information of each preprocessing object.

[0052] For each pre-processing object, all the performance data in the representation information needs to be collected and obtained. That is, each pre-processing object corresponds to multiple different types of data.

[0053] S123. Acquire all pre-processed objects whose status data fall into the same sterilization group status data interval, and set them into the same sterilization group.

[0054] The purpose of this step is to determine the characterization information of the obtained pretreatment objects, and then detect the characterization information, and set the pretreatment objects with the same characterization information into the same sterilization group to achieve clustering of the pretreatment objects.

[0055] Here, the representation information of all preprocessed objects is obtained, and all data in the representation information are compared one by one.

[0056] Here, all pretreatment objects with the same characterization information are set into the same sterilization group.

[0057] Among them, the so-called sterilization group refers to all devices on the sterilization and sorting production line that are responsible for pre-processing objects.

[0058] Considering that in the sorting of pre-processed objects, among the pre-processed objects that are usually input, the pre-processed objects with the same characterization information are usually clustered together. For example, for blueberries, within a period of time, the characterization information of the blueberries that are usually input is extremely identical or similar. Therefore, this can be used to analyze the characterization information of adjacent pre-processed objects and then determine the sterilization group to which different pre-processed objects belong. Specifically: S1231, step 1, obtaining representation information of the first pre-processed object to obtain a first object state data group.

[0059] The purpose of this step is to use the characterization information of the first pre-treated object as a judgment basis, so that the characterization data corresponding to all subsequent sterilization groups can be obtained based on this basic data.

[0060] Here, the characterization information of the first pre-processed object in the entire production line is obtained, which obviously includes all measurable data in the characterization information.

[0061] Wherein, for the representation information that can be obtained, the representation information is directly used as the first object state group.

[0062] Among them, for the representation information of the preprocessing object, it is necessary to be able to record all information.

[0063] S1232, step 2, after obtaining the first object status data group, set the first object status data group as the status data group of the first sterilization group.

[0064] The purpose of this step is to directly obtain the information label of the first sterilization group after acquiring the first object status data group, and to set the first pre-treated object into the first sterilization group.

[0065] The characterization information of the first pre-processed object is directly set as the information tag of the first sterilization group, and the information tag is used to record the characterization information of the pre-processed objects that can be carried by the sterilization group.

[0066] Among them, the first pre-treated object can be directly put into the first sterilization group.

[0067] S1233, step 3, obtaining representation information of the second pre-processed object to obtain a second object state data group.

[0068] The purpose of this step is to obtain the source information after obtaining the first pretreatment object, and then analyze the sterilization group based on the characterization information of the first pretreatment object.

[0069] Wherein, the representation information of the second preprocessed object is directly measured.

[0070] The representation information of the second pre-processed object is directly set as the second object state data group.

[0071] S1234, step 4, compare the second object status data group with the first object status data group. If the deviation between any status data in the second object status data group and the same status data in the first object status data group is higher than the preset deviation, set the second pre-treated object to the second sterilization group; otherwise, set it to the first sterilization group.

[0072] The purpose of this step is to analyze the data of the first and second preprocessed objects, and then analyze whether there is a deviation between the two data. In other words, based on this step, the specific ideas adopted in the implementation of the entire technical solution can be given.

[0073] The second object state data is directly compared with the first object state data, and the specific comparison process involves all data in the representation information.

[0074] For the first and second object state data groups, it is necessary to determine the deviation of all similar state data therein, and compare the obtained deviation with the preset deviation.

[0075] Among them, the preset inspection degree is set based on the corresponding data of the relevant characterization information of fresh fruits and vegetables at the same level. Taking blueberries as an example, the characterization information of superior products and the characterization information of medium products may involve significantly different characterization information parameters. Therefore, in the specific processing, it is necessary to directly set the preset deviation degree based on the deviation degree of similar parameters of these two fruit grades.

[0076] Among them, in the first and second object status data groups, when the deviation of the detection data of any characterizing information does not match its corresponding preset deviation, it is considered that the first and second pre-treated objects belong to different fruit grades, or have different states such as maturity and moisture content. In this case, the first and second pre-treated objects are set to different sterilization groups.

[0077] Among them, if it is found that all data in the status data groups in the first and second pretreatment objects are the same, that is, all data in the characterization information are the same (that is, the deviation is not higher than the preset deviation), the second pretreatment object can be set to the first sterilization group.

[0078] S1235, step 5, according to the method used in steps 1 to 4 and so on, compare all the pretreatment objects to be tested with the status data groups corresponding to all the sterilization groups that have been generated. If the deviation between all the status data in the status data group of the pretreatment object to be tested and the similar status data in the status data group corresponding to any sterilization group is not higher than the preset deviation, the pretreatment object to be tested is set to the corresponding sterilization group; otherwise, a new sterilization group is created.

[0079] The purpose of this step is to avoid using the same pulsed strong light parameters for pre-treated objects with different parameters in the entire batch that need to be sterilized. Therefore, reasonable grouping is required during the processing to ensure that the same pulsed strong light can be used for all pre-treated objects in the sterilization group.

[0080] For each pre-processed object, the characterization information of all pre-processed objects is measured according to the method described in steps 1 to 4, and the measurement results are used for comparison with other obtained data sets.

[0081] Among them, all the obtained status data groups need to be compared with the status data groups corresponding to all the previously generated sterilization groups to determine whether there is a situation where the deviation is too high.

[0082] The method for comparing the deviation is exactly the same as that in steps S1231 to S1234 and will not be described again here.

[0083] Among them, for the status data group corresponding to the sterilization group, all the data therein need to be compared individually.

[0084] When comparing the obtained state data group with the obtained sterilization group, the method of first comparing the state data group of the sterilization group into which the previous pre-processed object falls and then comparing other sterilization groups can be used to improve efficiency.

[0085] In some embodiments, the comparison process of the state data group of the pre-treated object and the generated sterilization groups may be performed in a comparison order from the first generated sterilization group to the last sterilization group.

[0086] Among them, when it is found that the deviation between the status data of the pretreatment object and all similar status data in the status data group corresponding to any sterilization group is not higher than the preset deviation, it is considered that the pretreatment object needs to be set in the sterilization group.

[0087] If it is found that the state data group of the pre-processed object cannot have any corresponding relationship with all the generated sterilization groups, a new sterilization group needs to be created.

[0088] The beneficial effect of step S120 is that for fresh fruits and vegetables that need to be sterilized, pre-treated objects with the same maturity, grade and other information can be set into the same sterilization group, so that in the subsequent specific pulsed strong light sterilization, the pulsed strong light parameters can be set directly based on the sterilization group, without the need to set the pulsed strong light parameters based on the individual pre-treated objects, thereby fully improving the sterilization efficiency.

[0089] As described in step S130, the purpose of this step is to achieve reasonable setting of pulsed light parameters, that is, to achieve early and accurate arrangement of pulsed light coefficients, and to sort the sterilization groups to ensure that the sorting of pulsed light parameters is reasonable. Specifically: S131. Acquire the number of pre-treated objects in all the sterilization groups in real time, and acquire the growth rate of the number of pre-treated objects.

[0090] The purpose of this step is to set a reference value during the sorting process of the sterilization groups. This step can set the reference value according to the function and characteristics of the sterilization groups.

[0091] The number of pre-treated objects in each sterilization group is obtained in real time.

[0092] The growth rate of the number of pre-treated objects in each sterilization group over a period of time, especially a short period of time, is obtained.

[0093] Among them, a sterilization group with a higher growth rate means that the growth rate of the pre-treated objects in the sterilization group will be higher in the past and in the future. A high growth rate means that in the current production line, the proportion of pre-treated objects with the same characterization information as that of the sterilization group is extremely high. Therefore, a high growth rate means that the sterilization group is easier to be filled.

[0094] S132. Sort the growth rates to obtain a sorting result of the sterilization group.

[0095] The purpose of this step is to obtain the ranking results of the sterilization groups based on the obtained growth rate data, so as to lay the foundation for the determination of sterilization priorities.

[0096] Here, for all the obtained growth rates, the data are sorted.

[0097] The obtainable growth rates may be sorted in order from large to small or from small to large, and this application does not impose any limitation.

[0098] S133. Obtain the sterilization priority of the sterilization group according to the sorting result of the sterilization group.

[0099] The purpose of this step is to directly set the sterilization priority of the sterilization group based on the sorting result after obtaining the sorting result of the sterilization group.

[0100] Among them, for the sterilization priority of the sterilization group, the sterilization priority can be directly obtained according to the obtained sorting result of the sterilization group.

[0101] Among them, the sterilization group with the largest growth rate has the highest sterilization priority.

[0102] Among them, the so-called sterilization priority refers to the order of entering the specific pulsed light sterilization module during the sterilization process of the pre-treated object. The higher the priority, the more quickly it is necessary to enter the pulsed light sterilization module.

[0103] The beneficial effect of step S130 is that, in a specific sterilization process, there will usually be a clustering effect for pretreatment objects that are basically the same, and such pretreatment objects are more likely to fill the corresponding sterilization group. In order to improve the efficiency of the sterilization process, it is necessary to give priority to the sterilization group in which such pretreatment objects are located, so that the sterilization process can be sorted according to the growth rate.

[0104] As described in step S140, the purpose of this step is to obtain the order of the sterilization groups in the future after obtaining the priority of the sterilization groups, so as to set the order of the pulsed light parameter groups. In the subsequent implementation of the technical solution, the pulsed light parameters can be set in advance according to this order, without having to set the pulsed light parameters independently for each sterilization group, so as to achieve the purpose of improving control efficiency and reducing control costs. Specifically: S141. Based on the characterization information of the pre-processed object of the sterilization group, obtain a pulsed intense light parameter group corresponding to the sterilization group.

[0105] The purpose of this step is to effectively maintain the vitamin C content during the pulsed strong light sterilization process. Taking into account that unreasonable pulsed strong light parameters can easily promote the hydrolysis of vitamin C during the pulsed strong light irradiation of vitamin C, it is obviously difficult to maintain the vitamin C content in this case. Therefore, the purpose of this application is to set a pulsed strong light parameter group corresponding to the characterization information based on the characterization information.

[0106] Among them, it is necessary to determine the limit quantity in the pulsed intense light sterilization process, which includes the sterilization degree parameters that can be produced and the reduction in vitamin C content, and establish an equation. The limit equation is: ; in, σIndicates the sterilization degree value in pulsed light sterilization technology; R Indicates the amount of reduction in vitamin C content; m Indicates the parameter type index in the pulsed light parameter group; n Indicates the total number of parameter type indexes in the pulsed light parameter group; a m and b m In the equation of sterilization degree and vitamin C content, m The weights of the parameter types; L m Indicates the m The specific value of the parameter type.

[0107] The weights mentioned in the above equation can be obtained based on experiments.

[0108] Among them, based on the above equations, the allowable value of the reduction amount based on vitamin C and the allowable value of the sterilization degree parameter can be obtained, and the m That is to say, for all parameters in the pulsed light parameter group, the numerical range of the corresponding parameter type can be obtained. The representation of each type of pulsed light parameter obtained is: ; in, I Lm Indicates the m The parameter range of pulsed intense light sterilization is as follows.

[0109] Based on the sterilization priorities of the sterilization groups, obtaining a ranking of the sterilization groups; According to the order of the sterilization groups, the order of the pulsed intense light parameter groups corresponding to the sterilization groups is set.

[0110] In some embodiments, the pulsed light parameters are further adjusted, and the equation is: ; in, I Lm Indicates the m Parameter range of pulsed intense light sterilization; M k Indicates the k The maturity of the pretreatment object as represented by the characterization information of each sterilization group; p Indicates the number index of the sterilization group; q Indicates the total number of sterilization group indexes; M p Indicates the p Maturity of each sterilization group; min L mIndicates the m The minimum value of the pulse light parameter; max L m Indicates the m The maximum value of the pulsed light parameter.

[0111] The maturity can be determined according to the following equation: ; in, M Indicates the maturity of pretreated objects within the sterilization group; q 1 Indicates the weight of the reflectivity level set based on variety information in the maturity result; q 2 Indicates the weight of the color depth grade set based on variety information in the maturity result; i Indicates the number index of pre-processed objects in the sterilization group; j Indicates the total number of pre-processed objects in the sterilization group; S i Indicates the i reflectivity level of each pre-processed object; S Indicates the total reflectivity level of all pre-treated objects in the sterilization group, which can be the sum of the reflectivity levels of all pre-treated objects in all sterilization groups; C i Indicates the i Color depth level of each preprocessed object; C It represents the total color depth level of all pre-treated objects in the sterilization group, which can be the sum of the color depth levels of all pre-treated objects in all sterilization groups.

[0112] The beneficial effect of step S140 is that the sterilization priority of the sterilization group can be determined to obtain the ranking of the sterilization groups, and based on the ranking, the order of the sterilization groups arriving at the sterilization module in the future time period can be determined, and the pulsed strong light parameters can be adjusted based on the order to fully improve the adjustment efficiency of the pulsed strong light parameters. That is to say, there is no need to re-analyze each sterilization group, and a pulsed strong light parameter group is set based on each sterilization group, thereby realizing reasonable adjustment of the pulsed strong light parameter group.

[0113] However, in the actual implementation of the technical solution, there may be a situation where, when the pre-processed objects with a certain level and characterization information are about to be sorted, or have been sorted, the sorting scheme for the pulsed light parameter group based on the original sorting result is no longer applicable. Therefore, it is necessary to introduce other supplementary schemes to verify the order of the pulsed light parameter group. The number index of the specific pre-processed objects in the sterilization group is: S144. Predicting the predicted full load order of all the sterilization groups based on the order of the pulsed intense light parameter groups.

[0114] The purpose of this step is to determine the predicted full load order of the sterilization group based on the order of the pulsed light parameter groups after the order is determined.

[0115] Among them, the order of the pulsed light parameter groups is determined based on the growth rate of the sterilization group; if it is determined by the growth rate, it can be directly determined based on the growth rate of the pre-treated objects in the sterilization group.

[0116] Among them, for the pulsed strong light parameter groups that have been generated, the parameter groups are directly sorted and considered to be the sterilization groups that meet the order in the future period of time.

[0117] S145. Based on the predicted full-load order, predict the next sterilization group that will reach a full-load state to obtain the next predicted full-load sterilization group.

[0118] The purpose of this step is to directly match the predicted full load order of the sterilization group with the sterilization group on the production line after obtaining the predicted full load order of the sterilization group, so as to match the predicted result with the actual object on the production line.

[0119] Wherein, based on the predicted full load sequence, the sterilization group label in the predicted full load sequence is determined, and the corresponding sterilization group is determined based on the label.

[0120] Among them, after determining the corresponding sterilization group, it is necessary to directly determine the corresponding sterilization group information from the sterilization processing production line, and then directly predict the full load order of the sterilization group on the production line.

[0121] S146: Detect the full load status of all the sterilization groups in real time, and obtain the next fully loaded sterilization group.

[0122] The purpose of this step is to obtain the order of the pulsed light parameter groups, so that the sterilization groups to be sterilized in the future can be directly obtained. This fully utilizes the clustering characteristics of the pretreatment objects. That is, under normal circumstances, pretreatment objects with the same or similar characterization information show a clustering effect throughout the production line. Therefore, after the order prediction is performed, there is no need to determine the characterization information of each sterilization group and then calculate the pulsed light parameters. Instead, only verification is required, which can fully save control resources. In this step, it is necessary to verify whether the specific prediction results are correct and obtain the experimental group for comparison.

[0123] Among them, the full load status of all sterilization groups on the production line is detected in real time. In this process, the technical solutions of quantity counting and prediction are no longer used, but only full load status detection is performed.

[0124] There are many methods that can be used to detect the full load state, such as counting the number of sterilization groups, the position of the upper surface of the pre-treated objects in the sterilization group, etc.

[0125] The so-called next actually fully loaded sterilization group refers to the next fully loaded sterilization group obtained starting from the sterilization group currently in the sterilization module. This is the next actually fully loaded sterilization group.

[0126] S147. Compare the next predicted full-load sterilization group with the next measured full-load sterilization group. If they are the same, adjust the pulsed intense light parameters based on the order of the pulsed intense light parameter groups. If they are different, re-acquire the order of the pulsed intense light parameter groups.

[0127] The purpose of this step is to compare the next predicted full-load sterilization group with the actual full-load sterilization group to determine whether the order of the currently set pulsed light data groups is correct.

[0128] The next predicted full-load sterilization group and the next measured full-load sterilization group are directly compared.

[0129] The specific comparison method may be achieved by setting a number for each sterilization group, and then directly comparing whether the numbers of the next predicted full-load sterilization group and the next measured full-load sterilization group are the same.

[0130] Among them, if it is found that the next predicted full-load sterilization group and the next measured full-load sterilization group are the same, it is considered that the order of the currently used pulsed intense light data group is correct, and the pulsed intense light data group can continue to be adjusted based on the parameter order. If they are different, it means that the order of the currently used pulsed intense light data group is wrong, and the order of the pulsed intense light parameter group needs to be reset.

[0131] The beneficial effect of steps S144 to S147 is that the correctness of the order of the pulsed strong light parameter groups can be verified, so that when a change occurs in the aggregated pretreatment object, that is, when the next predicted full-load sterilization group and the next measured full-load sterilization group are different, the original parameter group order is incorrect and cannot be used anymore, but the pulsed strong light parameter group order must be re-acquired.

[0132] As described in step S150, the purpose of this step is to adjust the pulsed light parameters directly based on the order information after determining the order of the pulsed light data group, and to perform correct sterilization on all pre-treated objects in the sterilization group. Specifically: S151. Based on the order of the pulsed intense light parameter groups, adjust the pulsed intense light parameters before the pre-treated objects in the sterilization group enter the sterilization production line.

[0133] The purpose of this step is to perform corresponding operations according to the results obtained during the actual pulsed light sterilization operation, thereby achieving adjustments below the pulsed light parameters.

[0134] After the order of the pulsed intense light parameter groups is obtained, a corresponding relationship between each pulsed intense light parameter group and the sterilization group is directly established based on the result obtained in the above equation.

[0135] Among them, after obtaining the order of the pulsed strong light parameter groups and completing the sterilization operation of a certain sterilization group, the pulsed strong light parameter group information corresponding to the next sterilization group undergoing the sterilization operation is obtained and adjusted in advance.

[0136] Among them, for each sterilization group before entering the pulsed light sterilization module, the pulsed light parameter group needs to be implemented in advance.

[0137] S152. The pre-treated objects in the sterilization group are evenly spread out when entering the sterilization area to avoid overlapping of the pre-treated objects.

[0138] The purpose of this step is to ensure that the outer surface of each pre-treated object can be thoroughly sterilized, so it is necessary to avoid overlapping areas between pre-treated objects. This problem can obviously be circumvented by paving the area.

[0139] Among them, before the sterilization group enters the sterilization module, that is, before the actual sterilization operation is performed, all pre-treated objects in the sterilization group need to be evenly flattened to avoid the problem of overlapping pre-treated objects.

[0140] Among them, for the uniform tiling processing method of the pre-processed object, a corresponding tiling device can be used to perform processing to achieve an effective tiling operation.

[0141] S153. The pre-treated objects in the sterilization group are rotated while in the sterilization production line to ensure that the surface of the pre-treated objects can be completely sterilized and the sterilized objects are obtained.

[0142] The purpose of this step is to ensure that the surface of the pre-treated object can be completely sterilized when performing the specific sterilization treatment of the pre-treated object, so corresponding methods need to be adopted to achieve the goal.

[0143] Among them, in the sterilization process of the pre-treated object, the pre-treated object needs to be able to always keep a rotating state during the transmission process, so that fresh fruits and vegetables represented by blueberries can be completely sterilized.

[0144] Among them, the conveying device needs to have the ability to drive the pre-treated object to rotate, so that it can achieve complete sterilization of the surface of the pre-treated object through passive rotation.

[0145] After the pre-treated object is sterilized, the pre-treated object becomes a sterilized object.

[0146] The beneficial effect of step S150 is that after the order of the pulsed strong light parameter groups is determined, the pulsed strong light parameters of the next sterilization group entering the pulsed strong light sterilization area are adjusted according to the order, and the outer surface of the pretreated object is completely sterilized by adjusting the transmission method of the pretreated object.

[0147] As described in all the above steps, this application can achieve pulsed light sterilization of fresh fruits and vegetables, such as Figure 2 The figure shows a schematic diagram of a system for implementing a method for maintaining vitamin C content under pulsed strong light sterilization provided by an embodiment of the present application. The conveyor belt 1 is divided into different conveying lanes, and a pretreatment area is provided on the conveyor belt. The area processes the sterilized object to obtain a pretreated object, and then the obtained pretreated object is transferred to the area where the characterization information acquisition module is located. The characterization information acquisition module obtains the characterization information of the pretreated object, and sends the obtained information to the sterilization group construction module, thereby establishing a sterilization group based on the module. The sterilization group construction module then sends the construction information to the sterilization group predicted full load sequence module, and also to the pulsed strong light parameter group order verification module, thereby obtaining the order of the sterilization group based on the sterilization group construction module. The predicted pulsed strong light parameter group order is then generated based on the order, and the predicted pulsed strong light parameter group order is also verified. After passing the verification, the pulsed strong light emitting device group can adjust the pulsed strong light parameters based on the information of the sterilization group predicted full load sequence module.

[0148] Among them, such as Figure 3 As shown, it is a schematic top view of a group of pulsed strong light emitting devices for a method of maintaining vitamin C content under pulsed strong light sterilization provided by an embodiment of the present application. Among them, the pulsed strong light parameter determination module is connected to each pulsed strong light emitting device 2, so as to realize the separate control of each pulsed strong light emitting device 2 to adjust the parameters of the emitted pulsed strong light. For each conveying lane on the conveyor belt 1, no less than two pulsed strong light emitting devices 2 are arranged side by side (the number in the figure does not represent the actual number). At this time, it can be ensured that when the sterilized object has undergone the rotary sterilization treatment, it can be ensured that the surface of the pre-treated object can be subjected to the pulsed strong light sterilization operation by the corresponding pulsed strong light emitting device 2, so as to ensure that the pre-treated object obtains a complete sterilization treatment on the outer surface.

[0149] As described in step S160, the purpose of this step is that after the pulsed light sterilization treatment, the vitamin C in fresh fruits and vegetables will be more sensitive to temperature and light, and it is more likely to cause the problem of vitamin C hydrolysis. Therefore, appropriate environmental settings must be made after the sterilization treatment to achieve the maintenance of the vitamin C content. Specifically: S161. Obtain the refrigeration temperature based on the category of the pre-processing object.

[0150] The purpose of this step is that after sterilization, refrigeration is obviously required, and different pre-treated objects have different refrigeration temperature requirements. Therefore, in the specific treatment, the refrigeration temperature needs to be determined according to the category of the pre-treated object.

[0151] Among them, determine the category of the pre-processed object and its requirements for the refrigerated environment.

[0152] Among them, the refrigeration temperature of the sterilized object is determined according to the requirements of the refrigeration environment.

[0153] S162. Refrigerate the sterilized object based on the refrigeration temperature.

[0154] The purpose of this step is to refrigerate the sterilized objects after determining the refrigeration temperature.

[0155] After the refrigeration temperature is determined, the sterilized objects are placed in the corresponding refrigeration space.

[0156] Among them, for the temperature of the refrigerated environment, it is necessary to ensure that the temperature in the entire refrigerated environment remains stable.

[0157] Among them, when refrigerating, if you need to refrigerate and store a variety of different fresh fruits and vegetables in the same space, you need to ensure that these fresh fruits and vegetables have the same adaptability to the refrigeration temperature. For example, for blueberries, the refrigeration temperature is 4°C. If other fresh fruits and vegetables also need to be refrigerated, the refrigeration temperature requirement for other categories is also 4°C.

[0158] S163. The sterilized object is refrigerated in a light-free environment to prevent the vitamin C in the sterilized object from being hydrolyzed in a light environment after pulsed strong light sterilization.

[0159] The purpose of this step is to ensure that the refrigerated environment is light-free during the refrigeration process of the sterilized object, taking into account that the vitamin C in the sterilized object is more sensitive to light after the pulsed strong light sterilization treatment.

[0160] Among them, it is necessary to minimize the light exposure time in the refrigerated environment, and light-free treatment is required during long-term refrigeration to avoid the hydrolysis of vitamin C in the light environment.

[0161] The beneficial effect of step S160 is that by setting up a refrigerated environment and limiting the lighting environment, the vitamin C content in the sterilized object can be fully maintained.

[0162] As described in step S170, the purpose of this step is to adjust the pulsed light parameters when it is found that the vitamin C content of a sterilization group is insufficient after sterilization and refrigeration, so as to achieve reasonable maintenance of the vitamin C content based on the negative feedback concept. Specifically: S171. Sampling the refrigerated objects corresponding to all the characterization information to obtain experimental samples.

[0163] The purpose of this step is to obtain samples and then analyze them during the analysis of whether the pulsed light parameter group needs to be adjusted. This step is to obtain experimental samples.

[0164] Among them, sampling is performed on the refrigerated objects corresponding to all types of representation information to obtain experimental samples.

[0165] The so-called refrigerated objects corresponding to all the characterization information can be randomly sampled from the refrigerated sterilized objects based on the characterization information set in the information tags of all the sterilization groups, thereby obtaining experimental samples.

[0166] S172. Obtain an experimental sample in which the vitamin C content in the experimental sample is not higher than a preset vitamin C content, and obtain characterization information corresponding to the experimental sample and a corresponding pulsed intense light parameter group.

[0167] The purpose of this step is to conduct a specific comparison of the maintenance effect of the vitamin C content in the experimental samples, so as to determine whether the pulsed light parameters need to be adjusted.

[0168] Among them, the preset vitamin C content can be set based on the experience of the technicians, or the average decrease in vitamin C content of all samples from the time they enter the cold storage place to the sampling period can be obtained, and the preset vitamin C content can be calculated based on the average. Specifically, it is the vitamin C content of the sample when it enters the cold storage place minus the average decrease.

[0169] Among them, when it is found that the vitamin C content of the experimental sample is not higher than the preset vitamin C content, it is considered that the characterization information and the corresponding pulsed light parameter group corresponding to the experimental sample are unreasonable and need to be adjusted.

[0170] S173. Adjust the corresponding pulsed intense light parameter group to obtain an adjusted pulsed intense light parameter group.

[0171] The purpose of this step is to adjust the parameters in the unreasonable pulsed light parameter group accordingly after obtaining the unreasonable pulsed light parameter group.

[0172] In the specific parameter adjustment process, based on the numerical range obtained in step S141, other pulsed light parameters are selected and combined to obtain a new pulsed light parameter group.

[0173] S174. Establish a correspondence between the characterization information of the pre-treated object and the adjusted pulsed intense light parameter group, and use the adjusted pulsed intense light parameter group to sterilize the pre-treated object with the same characterization information as the experimental sample.

[0174] The purpose of this step is to use the parameter value after obtaining the new pulsed light parameter group. Obviously, further pulsed light parameter adjustment can also be performed.

[0175] For the obtained new pulsed intense light parameter group, a corresponding relationship between the new pulsed intense light parameter group and the characterization information is established.

[0176] Among them, in the subsequent use of the pulsed strong light parameter group, when it is found that the characterization information corresponding to a sterilization group is the data adjusted by the pulsed strong light parameter group, the original pulsed strong light parameter group of the sterilization group is adjusted to the new pulsed strong light parameter group.

[0177] In some embodiments, after a new pulsed intense light parameter group is put into use, it is necessary to focus on monitoring the vitamin C content of the sterilized object after refrigeration obtained by the pulsed intense light parameter group to analyze whether the adjusted pulsed intense light parameter group meets the maintenance requirements of the vitamin C content. Obviously, when the goal still cannot be achieved, the new pulsed intense light parameter group needs to be further adjusted.

[0178] The beneficial effects of this application include: 1. Achieving a reasonable setting for the sterilized objects. In the technical solution of this application, characterization parameters are obtained for the sterilized objects, and sterilized objects with the same basic parameters are selected based on all the characterization parameters and grouped. At the same time, the pulsed light parameters can be adjusted according to the grouping results, thereby avoiding the serious problem of vitamin C hydrolysis caused by unreasonable setting of the pulsed light parameters during the sterilization process.

[0179] 2. Improved sterilization efficiency of sterilized objects. The technical solution of this application realizes the correct sorting of sterilized objects. At the same time, considering that sterilized objects in the same state in fresh fruits and vegetables often have clusters, the priority is determined by recording the real-time number of sterilized objects in the sterilization group. At the same time, based on the priority, the order of pulsed strong light sterilization parameters in the next period of time is directly predicted. After passing the verification, the pulsed strong light parameters are directly adjusted according to the parameter order. This method does not need to recalculate the pulsed strong light parameters based on the characterization information of each sterilization group, so it can fully improve the sterilization efficiency.

[0180] 3. The full-process maintenance of vitamin C content is achieved. In the technical solution of this application, in addition to reasonably setting the pulsed strong light parameters based on the characterization information of the sterilized object to ensure that the vitamin C content can be fully increased during the sterilization process, after the sterilization treatment, it is also subjected to lightless refrigeration treatment. At the same time, based on the feedback adjustment concept, the pulsed strong light parameters used in the pulsed strong light sterilization process of the sterilized object are feedback-adjusted, thereby further achieving the maintenance of vitamin C content. From the overall perspective of the technical solution, the full-process maintenance of vitamin C content is achieved.
