真空(kong)包裝(zhuang)機(ji)廠的(de)真空包(bao)裝機增加充(chong)(chong)(chong)(chong)氣(qi)功能是(shi)(shi)(shi)有兩種(zhong)方(fang)(fang)式(shi)，一(yi)(yi)(yi)種(zhong)是(shi)(shi)(shi)氣(qi)嘴直接伸到(dao)(dao)產品(pin)袋(dai)(dai)子里面進(jin)行(xing)充(chong)(chong)(chong)(chong)氣(qi)的(de)，另一(yi)(yi)(yi)種(zhong)是(shi)(shi)(shi)把要(yao)充(chong)(chong)(chong)(chong)的(de)氣(qi)體先(xian)充(chong)(chong)(chong)(chong)滿(man)整個真空室，然后靠負壓(ya)差(cha)充(chong)(chong)(chong)(chong)滿(man)袋(dai)(dai)子。那(nei)究竟采(cai)用哪種(zhong)方(fang)(fang)式(shi)充(chong)(chong)(chong)(chong)氣(qi)好呢(ni)，這(zhe)里主要(yao)看客戶(hu)的(de)產品(pin)性質，單純來(lai)說肯定(ding)是(shi)(shi)(shi)直接沖到(dao)(dao)袋(dai)(dai)子里比(bi)較(jiao)好，這(zhe)樣(yang)置換(huan)的(de)又純還能省不少(shao)氣(qi)源(yuan)，但(dan)是(shi)(shi)(shi)大家一(yi)(yi)(yi)定(ding)要(yao)考慮好自(zi)己產品(pin)性質。如(ru)果產品(pin)是(shi)(shi)(shi)顆粒，我們可以采(cai)取起初一(yi)(yi)(yi)種(zhong)方(fang)(fang)法(fa)直接讓(rang)充(chong)(chong)(chong)(chong)氣(qi)嘴到(dao)(dao)袋(dai)(dai)子里進(jin)行(xing)充(chong)(chong)(chong)(chong)氣(qi)，但(dan)是(shi)(shi)(shi)如(ru)果你的(de)產品(pin)是(shi)(shi)(shi)粉末狀(zhuang)的(de)就(jiu)不能用起初一(yi)(yi)(yi)種(zhong)方(fang)(fang)法(fa)了，需要(yao)第二(er)種(zhong)在真空室充(chong)(chong)(chong)(chong)氣(qi)利用壓(ya)力差(cha)充(chong)(chong)(chong)(chong)滿(man)袋(dai)(dai)子。可是(shi)(shi)(shi)客戶(hu)又要(yao)要(yao)求(qiu)達到(dao)(dao)一(yi)(yi)(yi)定(ding)比(bi)例的(de)殘氧量，這(zhe)就(jiu)很矛盾了。
