真空包裝(zhuang)機廠的(de)真空(kong)包裝機增加充(chong)(chong)氣(qi)功能(neng)(neng)是(shi)(shi)(shi)(shi)有兩種(zhong)方式，一種(zhong)是(shi)(shi)(shi)(shi)氣(qi)嘴直接伸(shen)到(dao)產(chan)品袋(dai)(dai)(dai)子里面(mian)進行(xing)充(chong)(chong)氣(qi)的(de)，另一種(zhong)是(shi)(shi)(shi)(shi)把要(yao)(yao)充(chong)(chong)的(de)氣(qi)體(ti)先充(chong)(chong)滿(man)(man)整(zheng)個真空(kong)室(shi)(shi)，然后靠負壓(ya)(ya)差(cha)充(chong)(chong)滿(man)(man)袋(dai)(dai)(dai)子。那究(jiu)竟采(cai)用哪(na)種(zhong)方式充(chong)(chong)氣(qi)好呢，這(zhe)(zhe)里主要(yao)(yao)看客(ke)戶(hu)的(de)產(chan)品性質，單純來說肯定(ding)是(shi)(shi)(shi)(shi)直接沖(chong)到(dao)袋(dai)(dai)(dai)子里比較好，這(zhe)(zhe)樣置換的(de)又(you)純還能(neng)(neng)省不少氣(qi)源，但是(shi)(shi)(shi)(shi)大家一定(ding)要(yao)(yao)考慮好自己(ji)產(chan)品性質。如果(guo)產(chan)品是(shi)(shi)(shi)(shi)顆粒，我們(men)可以采(cai)取起初(chu)一種(zhong)方法直接讓充(chong)(chong)氣(qi)嘴到(dao)袋(dai)(dai)(dai)子里進行(xing)充(chong)(chong)氣(qi)，但是(shi)(shi)(shi)(shi)如果(guo)你的(de)產(chan)品是(shi)(shi)(shi)(shi)粉(fen)末狀的(de)就(jiu)不能(neng)(neng)用起初(chu)一種(zhong)方法了(le)，需要(yao)(yao)第(di)二種(zhong)在真空(kong)室(shi)(shi)充(chong)(chong)氣(qi)利用壓(ya)(ya)力差(cha)充(chong)(chong)滿(man)(man)袋(dai)(dai)(dai)子。可是(shi)(shi)(shi)(shi)客(ke)戶(hu)又(you)要(yao)(yao)要(yao)(yao)求(qiu)達(da)到(dao)一定(ding)比例(li)的(de)殘氧量，這(zhe)(zhe)就(jiu)很(hen)矛(mao)盾了(le)。
