实施例
请参阅图1，本实施例提供了一种罐装产品包装工艺，可以适用于将奶粉填充在铁听罐中。
本实施例提供的罐装产品包装工艺包括有如下步骤：
步骤S100、对空罐进行充保护气体，使空罐被保护气体填充满，也即实现了将空罐中的空气利用保护气体挤压出去的作用，空罐中含有的空气 量极少，利用后续的抽真空作业，大大减少了后续抽真空作业所需要的时间。
步骤S200、在充保护气体后的空罐内填充物料，空罐内存有的空气少，物料填充在空罐后，罐体内的空气含量少，后续的抽真空作业更加便捷。
步骤S300、对物料填充完成的罐体进行封罐，由于在充填物料工序前进行了充保护气体工序，罐体中的空气含量少，封罐时不需要进行充氮工序，节省了封罐工序的时间，且封罐过程中抽真空时由于罐体内空气含量少，抽真空时间减少，进一步缩短了封罐时间，提高了封罐效率，在保证包装速度不变的前提下，减少了与充填机配对的封罐机的数量，节省了成本。
本实施例提供的罐装产品包装工艺，在对空罐进行充填前进行充保护气体工序，充保护气体完成后，空罐进入到充填工位，在充填工位，利用充填机在空罐内充填物料，空罐内物料充填完成后，具有物料的罐体进入到封罐工位，在封罐机的作用下进行封罐工序。封罐完成后，即完成了罐装产品的包装。在罐装产品包装过程中，在充填工序前进行充保护气体工序，然后将充有保护气体的空罐输送至充填工位进行物料充填，既不会影响充填的效率，同时，在封罐工序过程中减少了充氮工序，节省了大量时间，大大提高了封罐的效率，这样，在不改变罐装产品包装速度的前提下，与充填机配对的封罐机的数量能够减少，减少了包装过程中的设备，减少了设备的占地面积，节省了成本，提高了企业的经济效益。
本实施例中，在进行空罐的充保护气体工序时，利用充保护气体机构进行充氮。充保护气体机构将保护气体吹入到空罐内并通过保护气体将空罐内原有的空气排出，达到充保护气体排出空气的目的。
可选的，充保护气体机构包括有惰性气储气罐、保护气体管以及空气排出管，在保护气体储气罐的出气口处连通保护气体管的一端，保护气体管的另一端连通空罐的罐口，同时，空气排出管的一端连通空罐的罐口，空气排出管的另一端用于将空气引出空罐。充保护气体时，空气排出管和保护气体管共同作用封盖在空罐的罐口处，保护气体储气罐的阀门开启后，保护气体从保护气体管内进入到空罐中，在此过程中，保护气体将空罐中的空气从空气排出管处排出，在设定时间内完成充保护气体作业。或者，可以设置空气检测仪，用于检测空罐中空气的含量，进而提高充保护气体的质量。检测时，可以通过检测空气中氧气的含量来判断是否完成充保护气体工序。
进一步的，充保护气体的工序可以在充有保护气体的密闭环境中进行，这样，能够提高空罐内空气排出的质量，保证后续物料填充完成后罐体内空气含量低，后续抽真空更加便捷。
充保护气体完成后，将空罐输送至充填工位进行物料充填工序。充填时，利用充填机进行物料的充填。充填机包括有盛放物料的料斗，料斗内放置好适量的物料后，将料斗的出料口对准空罐，料斗中的物料落入空罐内，空罐内充填足量的物料后，将空罐输送至封罐工位进行封罐工序。在进行空罐充填物料的同时对料斗进行充保护气体，这样，料斗中物料没有直接与空气接触，减少了在充填过程中随着物料进入空罐内的空气量，后续封罐时抽真空更加便捷。
在空罐中将物料充填完成后得到装有定量物料的罐体，罐体输送至封罐工位进行封罐处理。
在罐体输送过程中，罐体在充有保护气体的密闭环境下输送至封罐机 的封罐工位处。利用抽真空设备对罐体进行抽真空，降低罐体内的残氧量，然后再进行封罐，大大延长食品的保质期。在抽真空过程中，由于空罐进行了充氮处理，且物料填充时料斗进行了充氮处理，这样，物料填充完成后的罐体中空气量大大减少，抽真空步骤耗时短，提高了效率。
需要说明的是，在封罐工序中，先进行放盖工序，然后抽真空，然后将盖体封装在罐体的罐口处完成封盖工序。
需要说明的是，保护气体可以是氮气。罐装产品包装时，先对空罐进行充氮处理，然后，在充有氮气的密闭环境中将罐体输送至填充机的填充工位，在填料的同时对充填机的料斗进行充氮处理，填料完成后，将罐体在充有氮气的密闭环境下输送至封罐机进行封罐工序。在罐装产品包装过程中，在充填工序前进行充氮气工序，然后将充有氮气的空罐流转至充填工位进行物料充填，既不会影响充填的效率，同时，在封罐工序过程中减少了充氮工序，节省了大量时间，大大提高了封罐的效率，这样，在不改变罐装产品包装速度的前提下，与充填机配对的封罐机的数量能够减少，减少了包装过程中的设备，减少了设备的占地面积，节省了成本，提高了企业的经济效益。
在其他实施例中，保护气体还可以是氦气、氖气等其他稀有气体。
例如，改进前：
充填机运行速度：(50罐－60罐)/分钟，封罐机运行速度：(12罐－16罐)/分钟，此时，一台充填机需要配置四台封罐机。
改进后：
充填机运行速度：(50罐－60罐)/分钟，封罐机运行速度：(22罐－28罐)/分钟，此时，一台充填机仅需要配置三台封罐机。由此可知，通过对罐装产品包装工艺的改进，提高了设备利用率，减少设备投入，节省成本，同时提升封罐质量。
实施例
本实施例提供了一种罐装产品封罐系统，其包括依次设置的充氮机构、充填机以及封罐机，充氮机构用于对空罐充氮，充填机用于将完成充氮后的空罐填充物料，封罐机用于封盖完成物料充填后的罐体的罐口。利用充氮机构先对空罐进行充氮，充氮后的空罐运输至充填机处进行物料充填，物料充填完成后再输送至封罐机处进行抽真空封罐工序。这样的设备布置，在充填工序前进行充保护气体工序，然后将充有保护气体的空罐输送至充填工位进行物料充填，既不会影响充填的效率，同时，在封罐工序过程中减少了充氮工序，节省了大量时间，大大提高了封罐的效率。在不改变罐装产品包装速度的前提下，与充填机配对的封罐机的数量能够减少，减少了包装过程中的设备，减少了设备的占地面积，节省了成本，提高了企业的经济效益。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
