真空(kong)包(bao)裝機廠(chang)的(de)(de)(de)真空(kong)包裝(zhuang)機(ji)增加(jia)充(chong)(chong)氣(qi)功(gong)能(neng)是(shi)(shi)有兩種(zhong)(zhong)方式(shi)，一種(zhong)(zhong)是(shi)(shi)氣(qi)嘴(zui)直接(jie)伸到(dao)(dao)產(chan)品袋子里面進行充(chong)(chong)氣(qi)的(de)(de)(de)，另一種(zhong)(zhong)是(shi)(shi)把要(yao)(yao)充(chong)(chong)的(de)(de)(de)氣(qi)體先充(chong)(chong)滿(man)整(zheng)個(ge)真空(kong)室，然后靠負壓差充(chong)(chong)滿(man)袋子。那究竟采(cai)用(yong)哪(na)種(zhong)(zhong)方式(shi)充(chong)(chong)氣(qi)好(hao)呢，這(zhe)里主要(yao)(yao)看客戶(hu)的(de)(de)(de)產(chan)品性(xing)質，單純(chun)來說(shuo)肯定(ding)是(shi)(shi)直接(jie)沖到(dao)(dao)袋子里比較好(hao)，這(zhe)樣置(zhi)換的(de)(de)(de)又(you)純(chun)還能(neng)省不少氣(qi)源(yuan)，但(dan)是(shi)(shi)大家一定(ding)要(yao)(yao)考慮好(hao)自己(ji)產(chan)品性(xing)質。如果產(chan)品是(shi)(shi)顆粒(li)，我(wo)們可以采(cai)取起(qi)初(chu)一種(zhong)(zhong)方法直接(jie)讓充(chong)(chong)氣(qi)嘴(zui)到(dao)(dao)袋子里進行充(chong)(chong)氣(qi)，但(dan)是(shi)(shi)如果你的(de)(de)(de)產(chan)品是(shi)(shi)粉末狀的(de)(de)(de)就不能(neng)用(yong)起(qi)初(chu)一種(zhong)(zhong)方法了(le)，需要(yao)(yao)第二種(zhong)(zhong)在真空(kong)室充(chong)(chong)氣(qi)利用(yong)壓力差充(chong)(chong)滿(man)袋子。可是(shi)(shi)客戶(hu)又(you)要(yao)(yao)要(yao)(yao)求達到(dao)(dao)一定(ding)比例的(de)(de)(de)殘(can)氧量，這(zhe)就很(hen)矛盾了(le)。
