真空包裝機廠的真空(kong)包(bao)裝機增加充(chong)(chong)(chong)氣(qi)(qi)(qi)功能是(shi)(shi)有兩種(zhong)方式，一種(zhong)是(shi)(shi)氣(qi)(qi)(qi)嘴直接伸到(dao)產(chan)品(pin)袋(dai)子里(li)面(mian)進行充(chong)(chong)(chong)氣(qi)(qi)(qi)的，另一種(zhong)是(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)的氣(qi)(qi)(qi)體先充(chong)(chong)(chong)滿整個真空(kong)室(shi)，然(ran)后靠負壓差(cha)(cha)充(chong)(chong)(chong)滿袋(dai)子。那究竟采(cai)用(yong)哪種(zhong)方式充(chong)(chong)(chong)氣(qi)(qi)(qi)好(hao)呢，這(zhe)里(li)主(zhu)要(yao)(yao)看客戶的產(chan)品(pin)性(xing)質(zhi)，單(dan)純來(lai)說肯定(ding)是(shi)(shi)直接沖到(dao)袋(dai)子里(li)比(bi)較好(hao)，這(zhe)樣置換的又純還能省不少氣(qi)(qi)(qi)源，但(dan)是(shi)(shi)大家一定(ding)要(yao)(yao)考慮好(hao)自己(ji)產(chan)品(pin)性(xing)質(zhi)。如果(guo)產(chan)品(pin)是(shi)(shi)顆粒，我們可(ke)(ke)以采(cai)取起(qi)初一種(zhong)方法直接讓充(chong)(chong)(chong)氣(qi)(qi)(qi)嘴到(dao)袋(dai)子里(li)進行充(chong)(chong)(chong)氣(qi)(qi)(qi)，但(dan)是(shi)(shi)如果(guo)你的產(chan)品(pin)是(shi)(shi)粉末狀的就(jiu)不能用(yong)起(qi)初一種(zhong)方法了(le)(le)，需要(yao)(yao)第二種(zhong)在真空(kong)室(shi)充(chong)(chong)(chong)氣(qi)(qi)(qi)利用(yong)壓力差(cha)(cha)充(chong)(chong)(chong)滿袋(dai)子。可(ke)(ke)是(shi)(shi)客戶又要(yao)(yao)要(yao)(yao)求(qiu)達到(dao)一定(ding)比(bi)例的殘氧量，這(zhe)就(jiu)很矛盾了(le)(le)。
