真(zhen)空包(bao)裝機廠的(de)(de)真空包裝機增加充(chong)(chong)(chong)氣(qi)功能(neng)(neng)是(shi)(shi)有兩種方式(shi)，一(yi)種是(shi)(shi)氣(qi)嘴直(zhi)接(jie)(jie)伸到產(chan)(chan)(chan)(chan)品(pin)袋(dai)(dai)子(zi)里(li)(li)面進行充(chong)(chong)(chong)氣(qi)的(de)(de)，另一(yi)種是(shi)(shi)把要充(chong)(chong)(chong)的(de)(de)氣(qi)體先充(chong)(chong)(chong)滿(man)(man)整個真空室，然后靠負壓差(cha)充(chong)(chong)(chong)滿(man)(man)袋(dai)(dai)子(zi)。那究竟采用(yong)哪種方式(shi)充(chong)(chong)(chong)氣(qi)好呢(ni)，這里(li)(li)主(zhu)要看客戶的(de)(de)產(chan)(chan)(chan)(chan)品(pin)性質，單純來說肯定是(shi)(shi)直(zhi)接(jie)(jie)沖到袋(dai)(dai)子(zi)里(li)(li)比(bi)較好，這樣(yang)置(zhi)換的(de)(de)又(you)純還能(neng)(neng)省不少氣(qi)源，但是(shi)(shi)大(da)家(jia)一(yi)定要考慮好自己產(chan)(chan)(chan)(chan)品(pin)性質。如(ru)果產(chan)(chan)(chan)(chan)品(pin)是(shi)(shi)顆粒，我(wo)們可以采取起(qi)初一(yi)種方法直(zhi)接(jie)(jie)讓充(chong)(chong)(chong)氣(qi)嘴到袋(dai)(dai)子(zi)里(li)(li)進行充(chong)(chong)(chong)氣(qi)，但是(shi)(shi)如(ru)果你的(de)(de)產(chan)(chan)(chan)(chan)品(pin)是(shi)(shi)粉末(mo)狀的(de)(de)就不能(neng)(neng)用(yong)起(qi)初一(yi)種方法了，需要第二(er)種在(zai)真空室充(chong)(chong)(chong)氣(qi)利用(yong)壓力差(cha)充(chong)(chong)(chong)滿(man)(man)袋(dai)(dai)子(zi)。可是(shi)(shi)客戶又(you)要要求達到一(yi)定比(bi)例的(de)(de)殘氧量，這就很矛(mao)盾了。
