真空包裝機廠的(de)真(zhen)空(kong)包裝機增加充(chong)氣(qi)功(gong)能是(shi)(shi)(shi)有兩種(zhong)方式(shi)(shi)，一(yi)種(zhong)是(shi)(shi)(shi)氣(qi)嘴(zui)直(zhi)接伸到產(chan)品袋(dai)子(zi)(zi)里(li)面進行充(chong)氣(qi)的(de)，另一(yi)種(zhong)是(shi)(shi)(shi)把要(yao)充(chong)的(de)氣(qi)體先充(chong)滿整個真(zhen)空(kong)室，然后靠負(fu)壓(ya)差充(chong)滿袋(dai)子(zi)(zi)。那究竟采用(yong)(yong)哪種(zhong)方式(shi)(shi)充(chong)氣(qi)好呢，這(zhe)里(li)主(zhu)要(yao)看客(ke)戶的(de)產(chan)品性質，單純來說肯(ken)定是(shi)(shi)(shi)直(zhi)接沖到袋(dai)子(zi)(zi)里(li)比(bi)較好，這(zhe)樣置換的(de)又(you)純還能省(sheng)不(bu)少(shao)氣(qi)源，但是(shi)(shi)(shi)大家一(yi)定要(yao)考慮好自己(ji)產(chan)品性質。如果產(chan)品是(shi)(shi)(shi)顆粒(li)，我們可(ke)以采取(qu)起初一(yi)種(zhong)方法直(zhi)接讓充(chong)氣(qi)嘴(zui)到袋(dai)子(zi)(zi)里(li)進行充(chong)氣(qi)，但是(shi)(shi)(shi)如果你的(de)產(chan)品是(shi)(shi)(shi)粉末狀的(de)就(jiu)不(bu)能用(yong)(yong)起初一(yi)種(zhong)方法了(le)，需要(yao)第二種(zhong)在真(zhen)空(kong)室充(chong)氣(qi)利用(yong)(yong)壓(ya)力(li)差充(chong)滿袋(dai)子(zi)(zi)。可(ke)是(shi)(shi)(shi)客(ke)戶又(you)要(yao)要(yao)求達到一(yi)定比(bi)例的(de)殘氧量，這(zhe)就(jiu)很矛盾了(le)。
