真空(kong)包裝機廠的真(zhen)空包裝機增加充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)功能是(shi)有兩(liang)種(zhong)方(fang)(fang)式，一(yi)(yi)種(zhong)是(shi)氣(qi)(qi)(qi)嘴直接伸(shen)到(dao)產(chan)(chan)(chan)品袋(dai)子(zi)里面進行充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)的，另一(yi)(yi)種(zhong)是(shi)把要(yao)充(chong)(chong)(chong)(chong)(chong)的氣(qi)(qi)(qi)體先充(chong)(chong)(chong)(chong)(chong)滿整(zheng)個真(zhen)空室，然后靠負(fu)壓差充(chong)(chong)(chong)(chong)(chong)滿袋(dai)子(zi)。那(nei)究竟采用(yong)哪種(zhong)方(fang)(fang)式充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)好(hao)呢，這(zhe)(zhe)里主要(yao)看客(ke)戶的產(chan)(chan)(chan)品性質，單純來說肯(ken)定是(shi)直接沖(chong)到(dao)袋(dai)子(zi)里比較好(hao)，這(zhe)(zhe)樣置換的又(you)純還能省不(bu)少氣(qi)(qi)(qi)源，但(dan)是(shi)大家一(yi)(yi)定要(yao)考慮好(hao)自己(ji)產(chan)(chan)(chan)品性質。如果(guo)產(chan)(chan)(chan)品是(shi)顆粒，我們可以采取起(qi)初一(yi)(yi)種(zhong)方(fang)(fang)法(fa)(fa)直接讓充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)嘴到(dao)袋(dai)子(zi)里進行充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)，但(dan)是(shi)如果(guo)你的產(chan)(chan)(chan)品是(shi)粉末狀的就不(bu)能用(yong)起(qi)初一(yi)(yi)種(zhong)方(fang)(fang)法(fa)(fa)了，需要(yao)第二種(zhong)在真(zhen)空室充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)利用(yong)壓力差充(chong)(chong)(chong)(chong)(chong)滿袋(dai)子(zi)。可是(shi)客(ke)戶又(you)要(yao)要(yao)求(qiu)達到(dao)一(yi)(yi)定比例的殘氧量，這(zhe)(zhe)就很矛盾了。
