真(zhen)空(kong)包裝機廠的(de)真空(kong)包(bao)裝機(ji)增加充(chong)(chong)氣(qi)(qi)功(gong)能是(shi)有兩種(zhong)方(fang)(fang)式，一(yi)種(zhong)是(shi)氣(qi)(qi)嘴直接伸到(dao)產(chan)(chan)品(pin)袋子(zi)里(li)(li)面(mian)進(jin)行充(chong)(chong)氣(qi)(qi)的(de)，另一(yi)種(zhong)是(shi)把要(yao)充(chong)(chong)的(de)氣(qi)(qi)體先充(chong)(chong)滿(man)整個真空(kong)室，然后靠負(fu)壓(ya)差(cha)充(chong)(chong)滿(man)袋子(zi)。那究竟采用(yong)哪種(zhong)方(fang)(fang)式充(chong)(chong)氣(qi)(qi)好呢，這(zhe)(zhe)里(li)(li)主要(yao)看客戶的(de)產(chan)(chan)品(pin)性質(zhi)，單純(chun)(chun)來說肯(ken)定(ding)是(shi)直接沖到(dao)袋子(zi)里(li)(li)比(bi)較好，這(zhe)(zhe)樣(yang)置換的(de)又純(chun)(chun)還能省不(bu)少(shao)氣(qi)(qi)源(yuan)，但是(shi)大家一(yi)定(ding)要(yao)考慮好自己產(chan)(chan)品(pin)性質(zhi)。如果(guo)產(chan)(chan)品(pin)是(shi)顆粒，我們可以采取起初一(yi)種(zhong)方(fang)(fang)法直接讓充(chong)(chong)氣(qi)(qi)嘴到(dao)袋子(zi)里(li)(li)進(jin)行充(chong)(chong)氣(qi)(qi)，但是(shi)如果(guo)你的(de)產(chan)(chan)品(pin)是(shi)粉末狀的(de)就不(bu)能用(yong)起初一(yi)種(zhong)方(fang)(fang)法了，需要(yao)第二種(zhong)在真空(kong)室充(chong)(chong)氣(qi)(qi)利用(yong)壓(ya)力(li)差(cha)充(chong)(chong)滿(man)袋子(zi)。可是(shi)客戶又要(yao)要(yao)求達到(dao)一(yi)定(ding)比(bi)例的(de)殘氧量，這(zhe)(zhe)就很矛盾了。
