真(zhen)空(kong)包裝機廠的(de)(de)真(zhen)空包裝機增加充(chong)(chong)(chong)氣(qi)(qi)(qi)功(gong)能是(shi)(shi)有兩種(zhong)方(fang)式，一(yi)(yi)(yi)種(zhong)是(shi)(shi)氣(qi)(qi)(qi)嘴(zui)直(zhi)接伸到(dao)產(chan)品(pin)袋子(zi)(zi)(zi)里(li)(li)面進行(xing)充(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)(de)，另一(yi)(yi)(yi)種(zhong)是(shi)(shi)把(ba)要(yao)充(chong)(chong)(chong)的(de)(de)氣(qi)(qi)(qi)體先充(chong)(chong)(chong)滿(man)(man)整個真(zhen)空室，然后靠負壓差充(chong)(chong)(chong)滿(man)(man)袋子(zi)(zi)(zi)。那究竟(jing)采用(yong)哪種(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)(qi)(qi)好呢，這(zhe)(zhe)里(li)(li)主要(yao)看客戶的(de)(de)產(chan)品(pin)性(xing)質(zhi)，單純來說(shuo)肯定是(shi)(shi)直(zhi)接沖到(dao)袋子(zi)(zi)(zi)里(li)(li)比較好，這(zhe)(zhe)樣置換的(de)(de)又純還能省不少氣(qi)(qi)(qi)源，但是(shi)(shi)大(da)家(jia)一(yi)(yi)(yi)定要(yao)考慮好自己產(chan)品(pin)性(xing)質(zhi)。如果產(chan)品(pin)是(shi)(shi)顆粒，我(wo)們(men)可(ke)以采取(qu)起(qi)初一(yi)(yi)(yi)種(zhong)方(fang)法直(zhi)接讓充(chong)(chong)(chong)氣(qi)(qi)(qi)嘴(zui)到(dao)袋子(zi)(zi)(zi)里(li)(li)進行(xing)充(chong)(chong)(chong)氣(qi)(qi)(qi)，但是(shi)(shi)如果你的(de)(de)產(chan)品(pin)是(shi)(shi)粉末狀(zhuang)的(de)(de)就不能用(yong)起(qi)初一(yi)(yi)(yi)種(zhong)方(fang)法了，需要(yao)第(di)二(er)種(zhong)在真(zhen)空室充(chong)(chong)(chong)氣(qi)(qi)(qi)利用(yong)壓力差充(chong)(chong)(chong)滿(man)(man)袋子(zi)(zi)(zi)。可(ke)是(shi)(shi)客戶又要(yao)要(yao)求達(da)到(dao)一(yi)(yi)(yi)定比例的(de)(de)殘氧(yang)量，這(zhe)(zhe)就很矛盾了。
