真空包裝機廠的(de)(de)(de)(de)(de)真空包裝機增加(jia)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)功(gong)能是(shi)有兩種(zhong)(zhong)(zhong)方式，一(yi)種(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)(qi)(qi)(qi)嘴直接伸到產(chan)(chan)品(pin)(pin)袋子(zi)(zi)里面進行(xing)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)(de)，另一(yi)種(zhong)(zhong)(zhong)是(shi)把要(yao)充(chong)(chong)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體先充(chong)(chong)滿(man)整個真空室(shi)，然后靠(kao)負壓差(cha)充(chong)(chong)滿(man)袋子(zi)(zi)。那究竟采(cai)用哪種(zhong)(zhong)(zhong)方式充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)好呢，這(zhe)里主要(yao)看(kan)客戶(hu)的(de)(de)(de)(de)(de)產(chan)(chan)品(pin)(pin)性(xing)(xing)質，單純(chun)來(lai)說肯定(ding)是(shi)直接沖到袋子(zi)(zi)里比(bi)較好，這(zhe)樣(yang)置換的(de)(de)(de)(de)(de)又(you)純(chun)還(huan)能省不少氣(qi)(qi)(qi)(qi)(qi)源(yuan)，但是(shi)大(da)家一(yi)定(ding)要(yao)考(kao)慮好自己產(chan)(chan)品(pin)(pin)性(xing)(xing)質。如果產(chan)(chan)品(pin)(pin)是(shi)顆粒，我們(men)可以采(cai)取(qu)起(qi)初(chu)一(yi)種(zhong)(zhong)(zhong)方法直接讓(rang)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)嘴到袋子(zi)(zi)里進行(xing)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)，但是(shi)如果你的(de)(de)(de)(de)(de)產(chan)(chan)品(pin)(pin)是(shi)粉末狀的(de)(de)(de)(de)(de)就(jiu)不能用起(qi)初(chu)一(yi)種(zhong)(zhong)(zhong)方法了(le)，需要(yao)第二(er)種(zhong)(zhong)(zhong)在真空室(shi)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)利用壓力差(cha)充(chong)(chong)滿(man)袋子(zi)(zi)。可是(shi)客戶(hu)又(you)要(yao)要(yao)求達到一(yi)定(ding)比(bi)例的(de)(de)(de)(de)(de)殘(can)氧量，這(zhe)就(jiu)很矛盾(dun)了(le)。
