真空包(bao)裝機廠(chang)的(de)(de)真空包(bao)裝機增加充(chong)(chong)(chong)氣(qi)(qi)功能是(shi)(shi)(shi)有(you)兩(liang)種(zhong)(zhong)方(fang)(fang)式(shi)，一(yi)(yi)種(zhong)(zhong)是(shi)(shi)(shi)氣(qi)(qi)嘴直接伸到(dao)產(chan)(chan)品袋(dai)(dai)子(zi)里面(mian)進(jin)行充(chong)(chong)(chong)氣(qi)(qi)的(de)(de)，另(ling)一(yi)(yi)種(zhong)(zhong)是(shi)(shi)(shi)把要(yao)充(chong)(chong)(chong)的(de)(de)氣(qi)(qi)體先充(chong)(chong)(chong)滿整個真空室，然后靠負壓差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)。那究竟采用哪種(zhong)(zhong)方(fang)(fang)式(shi)充(chong)(chong)(chong)氣(qi)(qi)好呢(ni)，這(zhe)里主要(yao)看客(ke)戶的(de)(de)產(chan)(chan)品性質，單純來說(shuo)肯定是(shi)(shi)(shi)直接沖到(dao)袋(dai)(dai)子(zi)里比較好，這(zhe)樣置換的(de)(de)又(you)純還能省(sheng)不少氣(qi)(qi)源(yuan)，但是(shi)(shi)(shi)大家一(yi)(yi)定要(yao)考慮好自己產(chan)(chan)品性質。如(ru)果產(chan)(chan)品是(shi)(shi)(shi)顆粒，我們可(ke)以采取起初一(yi)(yi)種(zhong)(zhong)方(fang)(fang)法直接讓充(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)袋(dai)(dai)子(zi)里進(jin)行充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)(shi)(shi)如(ru)果你(ni)的(de)(de)產(chan)(chan)品是(shi)(shi)(shi)粉末狀(zhuang)的(de)(de)就不能用起初一(yi)(yi)種(zhong)(zhong)方(fang)(fang)法了(le)，需要(yao)第二種(zhong)(zhong)在(zai)真空室充(chong)(chong)(chong)氣(qi)(qi)利用壓力差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)。可(ke)是(shi)(shi)(shi)客(ke)戶又(you)要(yao)要(yao)求達到(dao)一(yi)(yi)定比例的(de)(de)殘(can)氧(yang)量，這(zhe)就很矛盾了(le)。
