The body may be composed of fat, protein, cellulose or water. For example, the spectrum acquiring means 13 may acquire 10 component spectra of the object, in which the components directed to the object are 3 spectra of fat, the components directed to the object are 5 spectra of protein, and the components directed to the object are 2 spectra of water. It is understood that, regarding fat, protein, fiber bundle or water having a predetermined waveform or a predetermined reflected light intensity range, if the waveform of the spectrum obtained by the spectrum obtaining device 13 is one of the predetermined waveforms or the spectrum obtained by the spectrum obtaining device 13 shows a reflected light intensity within one of the predetermined reflected light intensity ranges, the component spectrum is directed to the component. For example, when the output power of the light source is 20mW, the reflected light intensity range of the component of the object, fat, is between-35 and-26 dBm, and the reflected light intensity range of the component of the object, lean meat, is between-37 and-35 dBm. For example, when the intensity of reflected light from a detected portion of an object is-30 dBm, it can be inferred that the detected portion of the object is fat; when the intensity of the reflected light from the detected part of the object is-36 dBm, it can be estimated that the component of the detected part of the object is protein.
Wherein, the processor 14 is configured to calculate a content of each component of the object according to the plurality of component spectrograms; generating a target magnetic field strength value according to the content of each component of the object; the magnetic field generator 12 is controlled to adjust the magnetic field intensity to the target magnetic field intensity.
As described above, for example, the map acquisition means 13 may acquire 10 component maps of the object, in which 3 maps are directed to the component of the object that is fat, 5 maps are directed to the component of the object that is protein, and 2 maps are directed to the component of the object that is water. Processor 14 may calculate the substance content of the object from the number of spectra. For example, the fat content of the body is 30%, the protein content is 50%, and the water content is 20%. Or, the processor 14 determines a distribution color map of the components of the object according to the obtained plurality of component spectrograms, wherein a plurality of colors in the distribution color map may respectively correspond to different components of the object, and then calculates the content of each component according to the area of each color in the distribution color map.
It is understood that the content of the above-mentioned components refers to the ratio of the surface area of the components distributed on the surface of the object to the total surface area of the object. The corruption of the object mainly occurs gradually from the surface of the object to the interior of the object, so the technical means of identifying the components of the surface of the object and then determining the target magnetic field strength value is more beneficial to the fresh-keeping of the object.
The processor 14 generates a target magnetic field strength value based on the content of each component of the object. It will be appreciated that the target magnetic field strength values for different components of the same content will be different due to the different decay rates of the different components. For example, lean meat has protein as a major component and fat meat has fat as a major component. The main cause of protein putrefaction is protein degradation, and protein is decomposed into alkaline amine under the action of microorganism; fat rancidity is mainly caused by fat rancidity, wherein fat is decomposed into glycerin and free fatty acid under the action of lipase, and fat oxidation is caused by the reaction of the fat and oxygen and is the main cause of the fat rancidity. The rate of protein breakdown is greater than the rate of fat rancidity, so that the rate of lean meat spoilage is greater than that of fat meat spoilage. That is, for the same weight of two fresh meats, the first fresh meat has a protein content of 30% plus 70% fat; the second fresh meat has a protein content of 60% plus fat content of 40%, so the first fresh meat spoils more rapidly than the second fresh meat. It will be appreciated that the processor 14 generates a target magnetic field strength value for a first type of fresh meat that is different from a target magnetic field strength value generated for a second type of fresh meat.
The processor 14 also controls the magnetic field generating means 12 such that the strength value of the magnetic field is adjusted to the target magnetic field strength value. It will be appreciated that the processor 14 may control the electrical signals applied to the magnetic field generating means 12. In some cases, the smaller the current applied to the magnetic field generating device 12, the smaller the strength of the magnetic field generated by the magnetic field generating device 12; the greater the current applied to the magnetic field generating means 12, the greater the strength of the magnetic field generated by the magnetic field generating means 12.
It can be understood that the magnetic field generating device 12 is disposed in the fresh keeping container 10, and the magnetic field generated by the magnetic field generating device 12 acts on the object in the fresh keeping container 10 to keep the object fresh. Specifically, the magnetic field can inhibit the propagation of bacteria and microorganisms, prevent the rancidity of fat, delay the ripening of fruits and vegetables, and further improve the freshness of the objects in the freshness retaining container 10. Moreover, the magnetic field generating device 12 has a simple structure, is easy to implement, has low operation energy consumption, and can better assist the preservation container 10 in realizing the preservation of objects.
The freshness retaining container 10 provided by the embodiment of the application includes a container body 11, a magnetic field generating device 12, a map obtaining device 13 and a processor 14. The container body 11 has a cavity for receiving an object. It will be appreciated that the object has a plurality of components, such as protein, fat, cellulose, and the spoilage of each component is different. Therefore, a plurality of component spectrograms of the object are obtained by the spectrogram obtaining device 13, the processor 14 calculates the content of each component of the object according to the plurality of component spectrograms, calculates the target magnetic field strength value according to the content difference of the components of the object, and finally sets the strength value of the magnetic field in the accommodating cavity 111 as the target magnetic field strength value. Through the technical scheme, the corresponding target magnetic field strength value can be elaborately formulated according to the components of the component substances, and the aim of keeping the object fresh for a long time can be fulfilled.
In some embodiments, the composition of the object comprises a first component and a second component, and the processor 14 is configured to calculate a decay rate of the object based on the content of the first component and the content of the second component, and to calculate the target magnetic field strength value based on the decay rate.
It is understood that the decay rate varies with the composition of the object for the same temperature. Just because of the different decay rates, the target magnetic field strength values also differ. For example, the components of the object include protein, fat, or cellulose. Wherein the protein putrefaction speed is the maximum, the cellulose putrefaction speed is the minimum, and the fat putrefaction speed is intermediate. If the components of the object include protein, cellulose and fat, the decay rate of the object can be calculated from the ratio of the total components of the protein, cellulose and fat, and the target magnetic field intensity value can be calculated from the decay rate.
For example, the spectrum acquiring means 13 may acquire 10 component spectra of the object, wherein 4 spectra of the protein are directed to the component of the object, and 6 spectra of the cellulose are directed to the component of the object. Processor 14 may calculate the substance content of the object from the number of spectra. For example, the protein content of the object is 40% and the cellulose content is 60%. From the protein content and the cellulose content, the ratio coefficient of the protein content was set to 5 and the ratio coefficient of the cellulose content was set to 1, and therefore the putrefaction rate was 5 × 40% +1 × 60%, which was calculated to be 2.6.
In some cases, the first component in the above is a protein and the second component is a fat. The decay rate is calculated by the following formula:
V(y)＝k1*P(x)+k2*F(x)(k1＞0、k2＞0、k1＞k2)——(1)
wherein V (y) is the putrefaction speed, P (x) is the content of the protein, F (x) is the content of the fat, k1 is a first preset proportionality coefficient, and k2 is a second preset proportionality coefficient.
Wherein, the components of the object are different, and the preset proportionality coefficients are different. The first predetermined scaling factor and the second predetermined scaling factor may both be predetermined. Since the putrefaction rate of protein is greater than that of fat, the first predetermined scaling factor corresponding to protein is greater than the second predetermined scaling factor corresponding to fat.
For example, the spectrum acquiring apparatus 13 may acquire 10 component spectra of the object, wherein 3 spectra of the fat are directed to the component of the object, and 7 spectra of the protein are directed to the component of the object. Processor 14 may calculate the substance content of the object from the number of spectra. For example, the fat content of the body is 30% and the protein content is 70%. The putrefaction rate was 5 × 30% +8 × 70% as calculated by setting the first predetermined scaling factor to 5 and the second predetermined scaling factor to 8 according to the fat content and the protein content, respectively, to 7.1.
For another example, the spectrum acquiring device 13 may acquire 10 component spectra of the object, wherein 5 spectra of the fat are directed to the component of the object, and 5 spectra of the protein are directed to the component of the object. Processor 14 may calculate the substance content of the object from the number of spectra. For example, the fat content of the body is 50% and the protein content is 50%. The putrefaction rate was 5 × 50% +8 × 50% as calculated by setting the first predetermined scaling factor to 5 and the second predetermined scaling factor to 8 according to the fat content and the protein content, respectively, to 6.5.
Wherein, the target magnetic field intensity value is calculated by the following formula:
B(z)＝k3*V(y)(k3＞0)——(2)
wherein B (z) is the target magnetic field strength value, V (y) is the decay rate, and k3 is a third predetermined scaling factor. Wherein, the third predetermined scaling factor may be predetermined. The third predetermined factor may be 20, 30, 50, 100, etc.
For example, the fat content of the body is 30% and the protein content is 70%. The first preset scaling factor is 5, the second preset scaling factor is 8, and the third preset scaling factor is 50. The decay rate of the object was found to be 7.1 according to the formula (1), and the target magnetic field strength value was found to be 355mT according to the formula (2).
For another example, the body has a fat content of 50% and a protein content of 50%. The first preset scaling factor is 5, the second preset scaling factor is 8, and the third preset scaling factor is 100. The decay rate of the object is 6.5 according to the formula (1), and the target magnetic field strength value is 650mT according to the formula (2).
In some embodiments, the composition spectrum includes a first spectrum and a second spectrum, the composition of the object includes a first composition and a second composition, the processor 14 is configured to: calculating the content of the first component according to the number of the component spectrograms and the number of the first spectrograms; and calculating the content of the second component according to the number of the component spectrograms and the number of the second spectrograms. Wherein the first component is different from the second component. In some cases, the first component may be a protein and the second component may be a fat; in other cases, the first component may be a protein and the second component may be cellulose; in other cases, the first component may be a fat and the second component may be cellulose.
For example, the spectrum acquiring means 13 may acquire 10 component spectra of the object, wherein the number of the spectra directed to the first component is 4, and the number of the spectra directed to the second component is 6. The content of the first component or the second component, i.e., the content of the first component is 40% and the content of the second component is 60%, may be calculated from the ratio of the number of the spectrum of the first component or the number of the spectrum of the second component to the number of the total spectrum of the components.
Taking fresh meat as an example, the components of the fresh meat mainly include protein and fat, correspondingly, the component spectrogram includes a protein spectrogram and a fat spectrogram, the protein spectrogram points to the protein, and the fat spectrogram points to the fat. The processor 14 is configured to: calculating the content of the protein of the object according to the quantity of the component spectrograms and the quantity of the protein spectrograms; and calculating the fat content of the object according to the number of the component spectrograms and the number of the fat spectrograms. There are 2 spectra in which the component of the directed object is fat and 8 spectra in which the component of the directed object is protein. Processor 14 may calculate the substance content of the object from the number of spectra. For example, the fat content of the body is 20% and the protein content is 80%.
Referring to fig. 4, fig. 4 is a schematic view illustrating a first structure of an atlas acquisition apparatus according to an embodiment of the present application. In some embodiments, the pattern acquisition device 13 is a near-infrared laser fiber assembly including a plurality of probes 131, an infrared laser 132, and a near-infrared spectrum sensor 133, the plurality of probes 131 being connected to the infrared laser 132 and the near-infrared spectrum sensor 133. After each probe 131 pierces the object, the infrared laser 132 emits a detection laser to the probe 131, the detection laser generates a reflected light after being reflected by the object, and the reflected light is reflected to the near infrared spectrum sensor 133 to generate a component spectrum corresponding to the object.

The spectrum acquiring apparatus 13 may further comprise a coupler 134, an input end of the coupler 134 is connected to the infrared laser 132 and the near infrared spectrum sensor 133, and an output end of the coupler 134 is connected to the plurality of probes 131. It is understood that after the plurality of probes 131 penetrate the object, a plurality of reflected lights can be obtained, so as to obtain a plurality of component spectrograms, and further obtain the content of different components of the object.
In some embodiments, the pattern acquisition device 13 is disposed on an exterior surface of the container body 11. It can be understood that the arrangement on the outer surface of the container body 11 is more advantageous for the intuitive operation of the user because the spectrum acquiring device 13 needs to be in contact with the object to acquire the component spectrum of the object.
In some embodiments, the number of turns of the helmholtz coil can be adjusted so the processor 14 can adjust the number of turns of the helmholtz coil so that the strength value of the magnetic field generated by the helmholtz coil is within a target magnetic field strength interval.
In other embodiments, the different magnetic field parameters of the magnetic field may cause different preservation effects of the magnetic field on the food materials, and the optimal preservation magnetic field parameters of different types of food materials may be different. For example, the magnetic field required to achieve freshness preservation of the protein should be of a strength sufficient to inhibit microbial growth; the strength of the magnetic field required for realizing the fresh-keeping of the fat is enough to inhibit the rancidity of the fat; the strength of the magnetic field required by food materials such as dry goods, five cereals and the like which are easy to mildew meets the requirement of inhibiting the growth of mildew; the fruits and vegetables are stored, so that the nutrient substances are easy to lose due to respiration, and the strength of the magnetic field required by the fruits and vegetables can meet the requirements of inhibiting the enzyme activity participating in the respiration and reducing the consumption of the nutrient substances; the food material needing to be frozen has overlarge ice crystals in the freezing process, can puncture cell membranes of the food, can affect the eating taste due to juice loss after being thawed, and the strength of the required magnetic field can meet the requirement of inhibiting the growth of the ice crystals. Thus, the magnetic field generating means 12 further comprise a power supply assembly electrically connected to the helmholtz coil, the power supply assembly being configured to supply power to the helmholtz coil. It will be appreciated that the power supply assembly inputs an electrical signal to the helmholtz coil to adjust the magnetic field produced by the helmholtz coil. For example, the electrical signal may be a constant voltage that modulates the magnetic field generated by the Helmholtz coil into a static magnetic field; for another example, the electrical signal may be an alternating voltage, and the magnetic field generated by the helmholtz coil is adjusted to be an alternating magnetic field; for another example, the electrical signal may be a pulsed voltage that modulates the magnetic field generated by the Helmholtz coil into a pulsed magnetic field.
The adjustment of the magnetic field intensity generated by the magnetic field generating device 12 may be performed by changing the magnitude of the current or by changing the number of turns of the current-carrying helmholtz coil. It will be appreciated that the greater the value of the input current, the higher the magnetic field strength; the greater the number of turns of the energized coil, the higher the strength of the magnetic field.
It is understood that the number of helmholtz coils is plural, and referring to fig. 3, the helmholtz coils are respectively disposed on the inner wall 113 of the container body 11. The inner wall 113 of the container body 11 may include a bottom wall 1132, a top wall 1131 disposed opposite to the bottom wall 1132, and a side wall 1133 connected to the bottom wall 1132 and the top wall 1131, where the side wall 1133 includes a first sub-side wall, a second sub-side wall, a third sub-side wall, and a fourth sub-side wall connected in sequence, and the first sub-side wall, the second sub-side wall, the third sub-side wall, and the fourth sub-side wall may be enclosed to form the accommodating cavity 111.
For example, the number of helmholtz coils is 2, wherein one helmholtz coil is disposed on the first sub-sidewall and the other helmholtz coil is disposed on the third sub-sidewall. Alternatively, one of the helmholtz coils is disposed on the bottom wall 1132 of the freshness protection container 10, and the other is disposed on the top wall 1131 of the freshness protection container 10. For another example, when the number of helmholtz coils is 4, the helmholtz coils are respectively disposed on the first sub sidewall, the second sub sidewall, the third sub sidewall and the fourth sub sidewall.
In some embodiments, referring to fig. 3, the helmholtz coils are symmetrically disposed on the inner wall 113 of the container body 11. It will be appreciated that the symmetrically arranged helmholtz coils provide a more uniform distribution and strength of the magnetic field generated within the cavity. The helmholtz coil may be made of copper, aluminum, or any other material capable of generating a magnetic field by energization.
In some embodiments, the helmholtz coil is disposed on the first sub-sidewall, and the iron plate is disposed on the third sub-sidewall opposite to the first sub-sidewall, and the helmholtz coil interacts with the iron plate to make the distribution and intensity of the magnetic field generated in the cavity more uniform.
Please refer to fig. 2 and fig. 6, fig. 6 is a schematic flow chart of a preservation method according to an embodiment of the present disclosure.
The application also provides a preservation method, which is applied to a preservation container 10, wherein the preservation container 10 comprises a container body 11, a magnetic field generating device 12 and an atlas acquisition device 13, the container body 11 is provided with an accommodating cavity 111, the accommodating cavity 111 is used for accommodating an object and the magnetic field generating device 12, the magnetic field generating device 12 is used for generating a magnetic field, the atlas acquisition device 13 is used for acquiring a plurality of component spectrograms of the object, and the component spectrograms point to different components of the object, and the preservation method comprises the following steps:
and step 210, calculating the content of each component of the object according to the plurality of component spectrograms.
For example, the spectrum acquiring means 13 may acquire 10 component spectra of the object, in which the components directed to the object are 3 spectra of fat, the components directed to the object are 5 spectra of protein, and the components directed to the object are 2 spectra of water. The substance content of the object can be calculated according to the number of the spectrograms. For example, the fat content of the body is 30%, the protein content is 50%, and the water content is 20%. Or, a distribution color map of the components of the object may be determined according to the obtained plurality of component spectrograms, a plurality of colors in the distribution color map may respectively correspond to different components of the object, and the content of each component may be calculated according to the area of each color in the color map.
It will be appreciated that the target magnetic field strength values for the same amount of different components will be different due to the different decay rates of the different components. For example, the main component of lean meat is protein, and the main component of fat meat is fat, wherein the decomposition rate of protein is higher than the rancidity rate of fat, so the rancidity rate of lean meat is higher than that of fat meat. That is, for the same weight of two fresh meats, the first fresh meat has a protein content of 30% plus 70% fat; the second fresh meat has a protein content of 60% plus fat content of 40%, so the first fresh meat spoils more rapidly than the second fresh meat. It will be appreciated that the target magnetic field strength value generated for the first type of fresh meat is different from the target magnetic field strength value generated for the second type of fresh meat.
The magnetic field intensity value is adjusted to the target magnetic field intensity value by controlling the magnetic field generator 12. In one case, the current applied to the magnetic field generating means 12 may be controlled. For example, as the current applied to the magnetic field generating device 12 is smaller, the magnetic field generated by the magnetic field generating device 12 is smaller; the greater the current applied to the magnetic field generating means 12, the greater the magnetic field generated by the magnetic field generating means 12.
In some embodiments, the composition of the object includes a first component and a second component, and in the step of generating the target magnetic field intensity value according to the content of each of the components of the object, the freshness keeping method includes:
calculating the putrefaction speed of the object according to the content of the first component and the content of the second component; and calculating a target magnetic field strength value according to the decay speed.
It is understood that the decay rate varies with the composition of the object for the same temperature. Just because of the different decay rates, the target magnetic field strength values also differ. For example, the composition of the object includes protein, fat, or cellulose. Wherein the protein decay rate is the greatest, the cellulose decay rate is the least, and the fat decay rate is intermediate. If the components of the object include protein, cellulose and fat, the decay rate of the object can be calculated based on the proportion of the protein, cellulose and fat occupying the total components, and finally the target magnetic field intensity value can be calculated based on the decay rate.
For example, the spectrum acquiring means 13 may acquire 10 component spectra of the object, wherein 4 spectra of the protein are directed to the component of the object, and 6 spectra of the cellulose are directed to the component of the object. The substance content of the object can be calculated according to the number of the spectrograms. For example, the protein content of the object is 40% and the cellulose content is 60%. From the protein content and the cellulose content, the percentage coefficient of the protein content was set to 5 and the percentage coefficient of the cellulose content was set to 1, so that the putrefaction rate was 5 × 40% +1 × 60%, and calculated to be 2.6.
Wherein the first component is protein and the second component is fat. The decay rate is calculated by the following formula:
V(y)＝k1*P(x)+k2*F(x)(k1＞0、k2＞0、k1＞k2)——(1)
wherein V (y) is the putrefaction speed, P (x) is the content of the protein, F (x) is the content of the fat, k1 is a first preset proportionality coefficient, and k2 is a second preset proportionality coefficient.
Wherein, the components of the object are different, and the preset proportionality coefficients are different. The first preset proportionality coefficient and the second preset proportionality coefficient are preset. Since the decay rate of protein is greater than the decay rate of fat, the first predetermined scaling factor corresponding to protein is greater than the second predetermined scaling factor corresponding to fat.
For example, the spectrum acquiring apparatus 13 may acquire 10 component spectra of the object, wherein 3 spectra of the fat are directed to the component of the object, and 7 spectra of the protein are directed to the component of the object. The substance content of the object can be calculated according to the number of the spectrograms. For example, the fat content of the body is 30% and the protein content is 70%. From the fat content and the protein content, the percentage coefficient of the fat content was set to 5 and the percentage coefficient of the protein content was set to 8, and therefore the putrefaction rate was 5 × 30% +8 × 70%, which was calculated to be 7.1.
For another example, the spectrum acquiring device 13 may acquire 10 component spectra of the object, wherein 5 spectra of the fat are directed to the component of the object, and 5 spectra of the protein are directed to the component of the object. The substance content of the object can be calculated according to the number of the spectrograms. For example, the fat content of the body is 50% and the protein content is 50%. From the fat content and the protein content, the percentage coefficient of the fat content was set to 5 and the percentage coefficient of the protein content was set to 8, and therefore the putrefaction rate was 5 × 50% +8 × 50%, and calculated to be 6.5.
Wherein, the target magnetic field intensity value is calculated by the following formula:
B(z)＝k3*V(y)(k3＞0)——(2)
wherein B (z) is the target magnetic field strength value, V (y) is the decay rate, and k3 is a third predetermined scaling factor.
In some embodiments, the composition spectra include a first spectrum and a second spectrum, the composition of the object also includes a first composition and a second composition, the first spectrum is directed to the first composition, the second spectrum is directed to the second composition, and in the step of calculating the content of each composition of the object according to the plurality of composition spectra, the preservation method further includes: calculating the content of the first component according to the number of the component spectrograms and the number of the first spectrograms; and calculating the content of the second component according to the number of the component spectrograms and the number of the second spectrograms.
Wherein the first component is different from the second component. In some cases, the first component may be a protein and the second component may be a fat; in other cases, the first component may be a protein and the second component may be cellulose; in other cases, the first component may be a fat and the second component may be cellulose.
For example, the spectrum acquiring means 13 may acquire 10 component spectra of the object, wherein the number of the spectra directed to the first component is 4, and the number of the spectra directed to the second component is 6. The content of the first component or the second component, i.e., the content of the first component is 40% and the content of the second component is 60%, may be calculated from the ratio of the number of the spectrum of the first component or the number of the spectrum of the second component to the number of the total spectrum of the components.
Taking fresh meat as an example, the components of the fresh meat mainly include protein and fat, correspondingly, the component spectrogram includes a protein spectrogram and a fat spectrogram, the protein spectrogram points to the protein, and the fat spectrogram points to the fat. Calculating the content of the protein of the object according to the quantity of the component spectrograms and the quantity of the protein spectrograms; and calculating the fat content of the object according to the number of the component spectrograms and the number of the fat spectrograms. There are 2 spectra in which the component of the directed object is fat and 8 spectra in which the component of the directed object is protein. The substance content of the object can be calculated according to the number of the spectrograms. For example, the fat content of the body is 20% and the protein content is 80%.
