真空包裝(zhuang)機廠的(de)(de)(de)真空包裝機增加(jia)充(chong)(chong)(chong)氣功能是(shi)(shi)有兩種(zhong)方(fang)式，一種(zhong)是(shi)(shi)氣嘴直(zhi)(zhi)接(jie)伸到產(chan)品袋(dai)(dai)子(zi)(zi)里(li)(li)(li)面進行充(chong)(chong)(chong)氣的(de)(de)(de)，另一種(zhong)是(shi)(shi)把要(yao)充(chong)(chong)(chong)的(de)(de)(de)氣體先充(chong)(chong)(chong)滿整個真空室，然后靠(kao)負(fu)壓(ya)差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。那(nei)究竟采用(yong)哪種(zhong)方(fang)式充(chong)(chong)(chong)氣好(hao)呢(ni)，這里(li)(li)(li)主要(yao)看(kan)客戶的(de)(de)(de)產(chan)品性質，單純來說肯定是(shi)(shi)直(zhi)(zhi)接(jie)沖到袋(dai)(dai)子(zi)(zi)里(li)(li)(li)比(bi)較(jiao)好(hao)，這樣置換的(de)(de)(de)又(you)(you)純還能省不少氣源(yuan)，但是(shi)(shi)大家一定要(yao)考慮好(hao)自己產(chan)品性質。如果(guo)產(chan)品是(shi)(shi)顆粒，我們可以(yi)采取起(qi)初(chu)一種(zhong)方(fang)法直(zhi)(zhi)接(jie)讓充(chong)(chong)(chong)氣嘴到袋(dai)(dai)子(zi)(zi)里(li)(li)(li)進行充(chong)(chong)(chong)氣，但是(shi)(shi)如果(guo)你的(de)(de)(de)產(chan)品是(shi)(shi)粉末狀的(de)(de)(de)就不能用(yong)起(qi)初(chu)一種(zhong)方(fang)法了，需要(yao)第二種(zhong)在(zai)真空室充(chong)(chong)(chong)氣利用(yong)壓(ya)力差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。可是(shi)(shi)客戶又(you)(you)要(yao)要(yao)求達到一定比(bi)例的(de)(de)(de)殘氧量，這就很矛(mao)盾了。
