真空(kong)包裝機廠的真空包裝機增加充(chong)(chong)(chong)(chong)氣(qi)功(gong)能是(shi)(shi)有兩種(zhong)方式，一(yi)種(zhong)是(shi)(shi)氣(qi)嘴直(zhi)(zhi)接(jie)伸到(dao)(dao)產品袋(dai)(dai)子里面(mian)進行(xing)充(chong)(chong)(chong)(chong)氣(qi)的，另一(yi)種(zhong)是(shi)(shi)把(ba)要(yao)充(chong)(chong)(chong)(chong)的氣(qi)體(ti)先充(chong)(chong)(chong)(chong)滿(man)整個真空室(shi)，然(ran)后靠負壓差充(chong)(chong)(chong)(chong)滿(man)袋(dai)(dai)子。那究竟采用(yong)哪種(zhong)方式充(chong)(chong)(chong)(chong)氣(qi)好(hao)呢，這(zhe)里主(zhu)要(yao)看客(ke)戶的產品性質(zhi)，單純(chun)來說(shuo)肯定是(shi)(shi)直(zhi)(zhi)接(jie)沖到(dao)(dao)袋(dai)(dai)子里比(bi)較好(hao)，這(zhe)樣置換的又純(chun)還能省不少氣(qi)源，但是(shi)(shi)大家一(yi)定要(yao)考慮好(hao)自己產品性質(zhi)。如果產品是(shi)(shi)顆粒，我們可以采取起初(chu)一(yi)種(zhong)方法(fa)直(zhi)(zhi)接(jie)讓充(chong)(chong)(chong)(chong)氣(qi)嘴到(dao)(dao)袋(dai)(dai)子里進行(xing)充(chong)(chong)(chong)(chong)氣(qi)，但是(shi)(shi)如果你的產品是(shi)(shi)粉末狀的就不能用(yong)起初(chu)一(yi)種(zhong)方法(fa)了，需要(yao)第二種(zhong)在真空室(shi)充(chong)(chong)(chong)(chong)氣(qi)利用(yong)壓力(li)差充(chong)(chong)(chong)(chong)滿(man)袋(dai)(dai)子。可是(shi)(shi)客(ke)戶又要(yao)要(yao)求達到(dao)(dao)一(yi)定比(bi)例的殘氧量，這(zhe)就很矛盾(dun)了。
