真(zhen)空包裝機廠的(de)(de)(de)真空(kong)包裝(zhuang)機增加充(chong)(chong)氣(qi)功(gong)能是(shi)(shi)(shi)(shi)(shi)有兩種(zhong)方(fang)式(shi)，一(yi)種(zhong)是(shi)(shi)(shi)(shi)(shi)氣(qi)嘴直(zhi)接伸到(dao)(dao)產(chan)品袋(dai)子(zi)里(li)面進行(xing)充(chong)(chong)氣(qi)的(de)(de)(de)，另(ling)一(yi)種(zhong)是(shi)(shi)(shi)(shi)(shi)把(ba)要(yao)充(chong)(chong)的(de)(de)(de)氣(qi)體先充(chong)(chong)滿(man)(man)整個真空(kong)室(shi)，然(ran)后靠負(fu)壓差充(chong)(chong)滿(man)(man)袋(dai)子(zi)。那究竟采用哪種(zhong)方(fang)式(shi)充(chong)(chong)氣(qi)好呢，這(zhe)(zhe)里(li)主要(yao)看客戶(hu)的(de)(de)(de)產(chan)品性質(zhi)，單純來說肯(ken)定是(shi)(shi)(shi)(shi)(shi)直(zhi)接沖(chong)到(dao)(dao)袋(dai)子(zi)里(li)比較(jiao)好，這(zhe)(zhe)樣(yang)置換(huan)的(de)(de)(de)又純還能省不少氣(qi)源，但是(shi)(shi)(shi)(shi)(shi)大家一(yi)定要(yao)考慮好自(zi)己(ji)產(chan)品性質(zhi)。如果產(chan)品是(shi)(shi)(shi)(shi)(shi)顆粒，我(wo)們可以采取起(qi)(qi)初一(yi)種(zhong)方(fang)法(fa)直(zhi)接讓充(chong)(chong)氣(qi)嘴到(dao)(dao)袋(dai)子(zi)里(li)進行(xing)充(chong)(chong)氣(qi)，但是(shi)(shi)(shi)(shi)(shi)如果你的(de)(de)(de)產(chan)品是(shi)(shi)(shi)(shi)(shi)粉(fen)末狀的(de)(de)(de)就(jiu)不能用起(qi)(qi)初一(yi)種(zhong)方(fang)法(fa)了，需要(yao)第二(er)種(zhong)在真空(kong)室(shi)充(chong)(chong)氣(qi)利(li)用壓力差充(chong)(chong)滿(man)(man)袋(dai)子(zi)。可是(shi)(shi)(shi)(shi)(shi)客戶(hu)又要(yao)要(yao)求達到(dao)(dao)一(yi)定比例的(de)(de)(de)殘氧(yang)量，這(zhe)(zhe)就(jiu)很矛盾了。
