真空(kong)包裝機廠的(de)(de)真空(kong)(kong)包裝機增加(jia)充(chong)(chong)(chong)氣(qi)功能(neng)是(shi)有兩種(zhong)方(fang)式，一(yi)種(zhong)是(shi)氣(qi)嘴直(zhi)接伸到(dao)產(chan)品袋子(zi)(zi)里面進(jin)行(xing)充(chong)(chong)(chong)氣(qi)的(de)(de)，另(ling)一(yi)種(zhong)是(shi)把要(yao)(yao)(yao)充(chong)(chong)(chong)的(de)(de)氣(qi)體(ti)先充(chong)(chong)(chong)滿整個真空(kong)(kong)室(shi)，然后靠負(fu)壓差充(chong)(chong)(chong)滿袋子(zi)(zi)。那究竟采用(yong)哪種(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)好呢，這里主要(yao)(yao)(yao)看客戶(hu)的(de)(de)產(chan)品性(xing)質，單(dan)純來說肯定(ding)是(shi)直(zhi)接沖(chong)到(dao)袋子(zi)(zi)里比(bi)較好，這樣置換(huan)的(de)(de)又純還能(neng)省不少氣(qi)源(yuan)，但是(shi)大家一(yi)定(ding)要(yao)(yao)(yao)考慮好自己產(chan)品性(xing)質。如果產(chan)品是(shi)顆粒，我們可(ke)以采取起初一(yi)種(zhong)方(fang)法直(zhi)接讓充(chong)(chong)(chong)氣(qi)嘴到(dao)袋子(zi)(zi)里進(jin)行(xing)充(chong)(chong)(chong)氣(qi)，但是(shi)如果你的(de)(de)產(chan)品是(shi)粉末狀(zhuang)的(de)(de)就不能(neng)用(yong)起初一(yi)種(zhong)方(fang)法了(le)，需(xu)要(yao)(yao)(yao)第二種(zhong)在(zai)真空(kong)(kong)室(shi)充(chong)(chong)(chong)氣(qi)利用(yong)壓力(li)差充(chong)(chong)(chong)滿袋子(zi)(zi)。可(ke)是(shi)客戶(hu)又要(yao)(yao)(yao)要(yao)(yao)(yao)求達到(dao)一(yi)定(ding)比(bi)例(li)的(de)(de)殘氧(yang)量，這就很矛盾(dun)了(le)。
