工作原理

XL -系列真空灌装机具有独特的工作原理,它分为四个灌装阶段:施加真空、灌装开始、施加真空-继续灌装和排空并恢复大气压力。在真空灌装阶段,所有剩余空气能被有效去除并由液体取而代之。

下面说明一下这 4 个阶段分别是如何工作的:

第一阶段:施加真空

容器定位在密封垫后,立即对容器施加真空,以消除产品内腔或气穴内可能存在的自由空气和夹带的空气。

第二阶段:正式灌装

施加真空过程完成后,阀门被驱动到第二阶段,产品通过容器内的真空和重力状态被快速吸入容器内。

第三阶段:施加真空 - 继续灌装

在这一操作阶段,再次给容器施加真空,以灌装继续进行。在此“真空灌装”阶段,任何剩余的空气将被清除,并用液体取而代之,准确得到一个预先设定的顶空。吸入真空的任何液体回收由垂直式真空阱缓冲罐来完成。

第四阶段:排空 - 恢复大气环境

灌装和真空端口关闭,容器被排空,并返回到大气压力状态。
