真(zhen)空包裝機廠的(de)真空(kong)(kong)包裝機增加充(chong)(chong)氣(qi)(qi)(qi)功能是(shi)有兩(liang)種(zhong)(zhong)(zhong)方式(shi)，一種(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)(qi)嘴直(zhi)接(jie)伸到(dao)產(chan)品(pin)袋(dai)子(zi)(zi)里(li)面(mian)進行充(chong)(chong)氣(qi)(qi)(qi)的(de)，另一種(zhong)(zhong)(zhong)是(shi)把要充(chong)(chong)的(de)氣(qi)(qi)(qi)體先充(chong)(chong)滿(man)整個真空(kong)(kong)室，然后靠負(fu)壓(ya)差(cha)充(chong)(chong)滿(man)袋(dai)子(zi)(zi)。那究竟采用哪種(zhong)(zhong)(zhong)方式(shi)充(chong)(chong)氣(qi)(qi)(qi)好呢，這里(li)主要看客(ke)戶的(de)產(chan)品(pin)性質，單純來說(shuo)肯定是(shi)直(zhi)接(jie)沖到(dao)袋(dai)子(zi)(zi)里(li)比較(jiao)好，這樣置換的(de)又(you)純還能省不(bu)少氣(qi)(qi)(qi)源，但(dan)是(shi)大家(jia)一定要考(kao)慮(lv)好自己產(chan)品(pin)性質。如果(guo)產(chan)品(pin)是(shi)顆粒，我們可(ke)以采取起(qi)初一種(zhong)(zhong)(zhong)方法直(zhi)接(jie)讓充(chong)(chong)氣(qi)(qi)(qi)嘴到(dao)袋(dai)子(zi)(zi)里(li)進行充(chong)(chong)氣(qi)(qi)(qi)，但(dan)是(shi)如果(guo)你的(de)產(chan)品(pin)是(shi)粉末(mo)狀的(de)就(jiu)不(bu)能用起(qi)初一種(zhong)(zhong)(zhong)方法了，需要第(di)二種(zhong)(zhong)(zhong)在真空(kong)(kong)室充(chong)(chong)氣(qi)(qi)(qi)利(li)用壓(ya)力(li)差(cha)充(chong)(chong)滿(man)袋(dai)子(zi)(zi)。可(ke)是(shi)客(ke)戶又(you)要要求達到(dao)一定比例(li)的(de)殘氧(yang)量，這就(jiu)很矛盾了。
