进一步优选地,第一磁体221和第二磁体222均是电磁线圈,以通过控制流经第一磁体221和/或第二磁体222的电流的大小,来调整第一磁体221和第二磁体222产生的磁场的强度。当然,本领域技术人员也可以根据需要,将第一磁体221和/或第二磁体222设置为永磁铁或永磁铁与电磁线圈的组合。Further preferably, both the

本领域技术人员能够理解的是,由于第一导磁构件231和第二导磁构件232能够禁锢第一磁体221和第二磁体222产生的磁感线,并使磁感线在第一导磁构件231和第二导磁构件232之间均匀分布,所以第一导磁构件231和第二导磁构件232不仅能够减少第一磁体221和第二磁体222外散到储物空间2101外侧的磁场,而且还能够辅助第一磁体221和第二磁体222在储物空间2101内形成强度均匀的磁场。Those skilled in the art can understand that, since the first magnetically
本领域技术人员还能够理解的是,储物空间2101内强度均匀的磁场能够使其内各个区域的被储藏物所受到的磁场作用相同,进而使储物空间2101内各个区域的被储藏物具有相同的保鲜效果。Those skilled in the art can also understand that the magnetic field with uniform strength in the

图10是本发明另一些实验中食材所处磁场强度和汁液流失率的关系图。Fig. 10 is a graph showing the relationship between the magnetic field strength of the ingredients and the juice loss rate in other experiments of the present invention.
在本发明中,磁体组件220和导磁组件230配置成,使储物空间2101内的磁感应强度为预设数值,预设数值的取值范围为1mT至10mT。例如,预设数值可以是1mT、4mT、5mT、6.5mT、7.8mT、10mT等。In the present invention, the
其中,1000mT=1T,T为用于表示磁感应强度的物理量——特斯拉。Among them, 1000mT=1T, and T is a physical quantity used to represent the magnetic induction intensity—Tesla.
如图7所示,在本发明的一些实验中,将三文鱼放置在0-12mT的匀强磁场中,存储10天,然后评估存储后的TVB-N值。其中,TVB-N是肉类三文鱼评价品质非常重要的评价指标之一,它主要代表三文鱼中蛋白质腐败变质的程度,国标规定新鲜畜产品TVB-N的限值为12mg/100g。As shown in Figure 7, in some experiments of the present invention, salmon were placed in a uniform magnetic field of 0-12mT, stored for 10 days, and then the TVB-N value after storage was evaluated. Among them, TVB-N is one of the most important evaluation indicators for evaluating the quality of meat salmon. It mainly represents the degree of protein spoilage in salmon. The national standard stipulates that the limit of TVB-N for fresh livestock products is 12mg/100g.
从图7中可以看出,1-10mT的磁场强度下存放的三文鱼10天后TVB-N值小于12mg/100g,三文鱼中蛋白质腐败变质的程度较低。It can be seen from Figure 7 that the TVB-N value of salmon stored under a magnetic field strength of 1-10mT is less than 12mg/100g after 10 days, and the degree of protein spoilage in salmon is relatively low.
如图8所示,在本发明的一些实验中,将牛肉放置在-4℃,0-12mT的匀强磁场中,存储10天,然后评估存储后的汁液流失率值。As shown in Figure 8, in some experiments of the present invention, the beef was placed in a uniform magnetic field of -4°C and 0-12mT, stored for 10 days, and then the juice loss rate value after storage was evaluated.
从图8中可以看出,1-10mT的磁场强度下存放的牛肉,10天后汁液流失率值小于6%,其它都是大于6%。这主要是因为牛肉在1-10mT以外的磁场强度下在-4℃下会冻结,所以汁液流失率大;但是牛肉在1-10mT的磁场强度下没有冻结,所以汁液流失率小。It can be seen from Fig. 8 that the juice loss rate of the beef stored under the magnetic field strength of 1-10mT is less than 6% after 10 days, and the others are all greater than 6%. This is mainly because the beef will freeze at -4°C at a magnetic field strength other than 1-10mT, so the juice loss rate is large; but the beef is not frozen at a magnetic field strength of 1-10mT, so the juice loss rate is small.
由此可见,为储物空间2101内的被储藏物提供1-10mT强度的磁场有利于被储藏物的保鲜,提升了磁场保鲜装置200和制冷设备对食材的保鲜性能。It can be seen that providing a magnetic field with a strength of 1-10 mT for the stored objects in the
如图9所示,在本发明的一些实验中,将500g牛里脊放置在0-8mT的匀强磁场中,然后施加相同的冷量。然后得出牛里脊在不同磁场强度下,从0℃降温至-5℃的时间。As shown in Fig. 9, in some experiments of the present invention, 500g of beef tenderloin was placed in a uniform magnetic field of 0-8mT, and then the same cooling was applied. Then the time for the beef tenderloin to cool down from 0°C to -5°C under different magnetic field strengths was obtained.
从图9中可以看出,牛里脊在1-5mT的磁场强度下,从0℃降温至-5℃的时间都小于70min。牛里脊在没有磁场的环境中,降温时间是85min。可见,1-5mT的磁场强度可显著增加食材冻结速度。It can be seen from Fig. 9 that the cooling time of the beef tenderloin from 0°C to -5°C under the magnetic field strength of 1-5mT is less than 70min. The cooling time of beef tenderloin in an environment without a magnetic field is 85 minutes. It can be seen that the magnetic field strength of 1-5mT can significantly increase the freezing speed of food.
如图10所示,在本发明的一些实验中,将牛肉放置在-18℃,0-8mT的匀强磁场中,存储10天,然后评估存储后的汁液流失率值。As shown in Figure 10, in some experiments of the present invention, the beef was placed in a uniform magnetic field of -18°C and 0-8mT, stored for 10 days, and then the juice loss rate after storage was evaluated.
从图10中不难看出,牛肉在1-5mT的磁场强度下,10天后汁液流失率值小于4%;而在没有磁场的常规环境中,牛肉的汁液流失率为4.7%。这主要是因为1-5mT强度下的磁场可以使冰晶生成得更小、更均匀,从而减小了食材的汁液流失率。It is not difficult to see from Figure 10 that under the magnetic field strength of 1-5mT, the juice loss rate of beef is less than 4% after 10 days; while in the conventional environment without magnetic field, the juice loss rate of beef is 4.7%. This is mainly because the magnetic field at a strength of 1-5mT can make ice crystals smaller and more uniform, thereby reducing the juice loss rate of ingredients.
因此,在本发明进一步的优选方案中,预设数值进一步的取值范围为1mT至5mT。Therefore, in a further preferred solution of the present invention, the preset value further ranges from 1 mT to 5 mT.
图11是本发明一些实施例中磁场保鲜装置上磁感应强度检测器的效果示意图。Fig. 11 is a schematic diagram of the effect of the magnetic induction intensity detector on the magnetic field preservation device in some embodiments of the present invention.
如图11所示,在本发明的一些实施例中,磁场保鲜装置200还包括磁感应强度检测器240,磁感应强度检测器240用于检测储物空间2101内磁场的磁感应强度,以根据检测到的磁感应强度来调整流经第一磁体211和/或第二磁体212的电流的大小。As shown in FIG. 11 , in some embodiments of the present invention, the magnetic

其中,磁感应强度检测器240可以是任意可行的装置,例如霍尔传感器。Wherein, the magnetic
可选地,磁感应强度检测器240设置在储物空间2101与第一磁体221相邻的一侧。例如,将磁感应强度检测器240设置在图2中所示储物空间2101的左侧壁、右侧壁或后侧壁上。Optionally, the
进一步可选地,磁场保鲜装置200包括多个磁感应强度检测器240,多个磁感应强度检测器240沿着第一磁体221靠近第二磁体222的方向间隔分布,以在第一磁体221靠近第二磁体222的方向上,测量储物空间2101内多个位置处的磁场强度,使得储物空间2101内各个部分在被储藏物具有隔磁性能时也能够具有较佳强度的磁场,保证了被储藏物的保鲜效果。Further optionally, the magnetic
举例说明,假如在没有被储藏物时,储物空间2101内各个部分的磁场强度为3mT。当储物空间2101内被储藏物填充满了,储物空间2101中间区域的磁场强度受被储藏物的阻隔,降低到了0.5mT。为了使储物空间2101内各个部分的被储藏物都具有较好的保险效果,增加进入第一磁体221和第二磁体222电流的大小,直至储物空间2101内各个部分的磁场强度都不小于1mT且不大于5mT。For example, if there is no object to be stored, the magnetic field strength of each part in the
基于前文的描述,本领域技术人员能够理解的是,通过将储物空间2101内的磁感应强度设置为预设数值,并将限定预设数值的取值范围为1mT至10mT,使得储物空间2101内的被储藏物能够处在优良的保鲜环境中,提升了被储藏物的保鲜效果。并且通过使多个磁感应强度检测器240沿着第一磁体221靠近第二磁体222的方向间隔分布,使得储物空间2101内各个部分在被储藏物具有隔磁性能时也能够具有较佳强度的磁场,保证了被储藏物的保鲜效果。Based on the foregoing description, those skilled in the art can understand that by setting the magnetic induction intensity in the
