真空包裝機(ji)廠的(de)真空包裝(zhuang)機(ji)增加充(chong)(chong)(chong)(chong)氣(qi)功能(neng)是(shi)有兩種(zhong)方式(shi)(shi)，一(yi)種(zhong)是(shi)氣(qi)嘴(zui)直接伸(shen)到(dao)產品(pin)(pin)袋(dai)(dai)子(zi)里面進(jin)行(xing)充(chong)(chong)(chong)(chong)氣(qi)的(de)，另一(yi)種(zhong)是(shi)把要(yao)(yao)(yao)充(chong)(chong)(chong)(chong)的(de)氣(qi)體先充(chong)(chong)(chong)(chong)滿(man)整(zheng)個真空室，然后靠負壓差充(chong)(chong)(chong)(chong)滿(man)袋(dai)(dai)子(zi)。那(nei)究(jiu)竟采用哪種(zhong)方式(shi)(shi)充(chong)(chong)(chong)(chong)氣(qi)好(hao)呢，這(zhe)里主(zhu)要(yao)(yao)(yao)看客戶(hu)的(de)產品(pin)(pin)性質，單純來說肯定是(shi)直接沖到(dao)袋(dai)(dai)子(zi)里比較好(hao)，這(zhe)樣置換的(de)又純還能(neng)省不(bu)少氣(qi)源，但(dan)是(shi)大家一(yi)定要(yao)(yao)(yao)考慮好(hao)自己產品(pin)(pin)性質。如(ru)果產品(pin)(pin)是(shi)顆(ke)粒，我們可以采取起初(chu)一(yi)種(zhong)方法(fa)直接讓充(chong)(chong)(chong)(chong)氣(qi)嘴(zui)到(dao)袋(dai)(dai)子(zi)里進(jin)行(xing)充(chong)(chong)(chong)(chong)氣(qi)，但(dan)是(shi)如(ru)果你(ni)的(de)產品(pin)(pin)是(shi)粉(fen)末狀的(de)就不(bu)能(neng)用起初(chu)一(yi)種(zhong)方法(fa)了(le)，需要(yao)(yao)(yao)第(di)二(er)種(zhong)在真空室充(chong)(chong)(chong)(chong)氣(qi)利(li)用壓力差充(chong)(chong)(chong)(chong)滿(man)袋(dai)(dai)子(zi)。可是(shi)客戶(hu)又要(yao)(yao)(yao)要(yao)(yao)(yao)求達到(dao)一(yi)定比例的(de)殘氧量，這(zhe)就很矛盾(dun)了(le)。
