真空包裝機廠(chang)的(de)(de)真(zhen)空(kong)包裝機增加充(chong)氣(qi)功能(neng)是(shi)有兩種(zhong)(zhong)(zhong)(zhong)方式，一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)氣(qi)嘴直(zhi)(zhi)接伸到(dao)產品袋(dai)(dai)子里面進行充(chong)氣(qi)的(de)(de)，另一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)把要(yao)充(chong)的(de)(de)氣(qi)體先充(chong)滿整個真(zhen)空(kong)室，然后靠負壓差(cha)充(chong)滿袋(dai)(dai)子。那究竟采用哪種(zhong)(zhong)(zhong)(zhong)方式充(chong)氣(qi)好呢，這里主要(yao)看客(ke)戶(hu)的(de)(de)產品性(xing)質(zhi)(zhi)，單純來說(shuo)肯定是(shi)直(zhi)(zhi)接沖(chong)到(dao)袋(dai)(dai)子里比較(jiao)好，這樣置換的(de)(de)又(you)純還能(neng)省不(bu)少(shao)氣(qi)源，但是(shi)大家一(yi)定要(yao)考慮(lv)好自(zi)己(ji)產品性(xing)質(zhi)(zhi)。如果(guo)產品是(shi)顆粒，我們可以采取起初(chu)一(yi)種(zhong)(zhong)(zhong)(zhong)方法直(zhi)(zhi)接讓充(chong)氣(qi)嘴到(dao)袋(dai)(dai)子里進行充(chong)氣(qi)，但是(shi)如果(guo)你(ni)的(de)(de)產品是(shi)粉末(mo)狀的(de)(de)就(jiu)不(bu)能(neng)用起初(chu)一(yi)種(zhong)(zhong)(zhong)(zhong)方法了，需要(yao)第二種(zhong)(zhong)(zhong)(zhong)在(zai)真(zhen)空(kong)室充(chong)氣(qi)利用壓力差(cha)充(chong)滿袋(dai)(dai)子。可是(shi)客(ke)戶(hu)又(you)要(yao)要(yao)求達到(dao)一(yi)定比例的(de)(de)殘氧量，這就(jiu)很(hen)矛盾了。
