真空(kong)包裝機廠的(de)(de)(de)真空(kong)(kong)包裝機增加充(chong)(chong)氣(qi)(qi)功能(neng)(neng)是(shi)(shi)有(you)兩種(zhong)方(fang)(fang)(fang)式(shi)(shi)，一(yi)種(zhong)是(shi)(shi)氣(qi)(qi)嘴直接伸(shen)到(dao)產品(pin)袋(dai)(dai)子里(li)(li)面進(jin)行充(chong)(chong)氣(qi)(qi)的(de)(de)(de)，另一(yi)種(zhong)是(shi)(shi)把要(yao)(yao)充(chong)(chong)的(de)(de)(de)氣(qi)(qi)體先(xian)充(chong)(chong)滿(man)整個真空(kong)(kong)室，然后靠(kao)負壓差(cha)(cha)充(chong)(chong)滿(man)袋(dai)(dai)子。那究竟采用哪種(zhong)方(fang)(fang)(fang)式(shi)(shi)充(chong)(chong)氣(qi)(qi)好(hao)(hao)呢(ni)，這(zhe)里(li)(li)主要(yao)(yao)看客戶的(de)(de)(de)產品(pin)性質(zhi)，單純來說肯定(ding)是(shi)(shi)直接沖到(dao)袋(dai)(dai)子里(li)(li)比(bi)較(jiao)好(hao)(hao)，這(zhe)樣置(zhi)換的(de)(de)(de)又純還(huan)能(neng)(neng)省不少氣(qi)(qi)源，但是(shi)(shi)大家一(yi)定(ding)要(yao)(yao)考(kao)慮好(hao)(hao)自己產品(pin)性質(zhi)。如果產品(pin)是(shi)(shi)顆粒，我們可(ke)以采取起(qi)初一(yi)種(zhong)方(fang)(fang)(fang)法(fa)直接讓(rang)充(chong)(chong)氣(qi)(qi)嘴到(dao)袋(dai)(dai)子里(li)(li)進(jin)行充(chong)(chong)氣(qi)(qi)，但是(shi)(shi)如果你的(de)(de)(de)產品(pin)是(shi)(shi)粉末狀(zhuang)的(de)(de)(de)就不能(neng)(neng)用起(qi)初一(yi)種(zhong)方(fang)(fang)(fang)法(fa)了，需要(yao)(yao)第(di)二種(zhong)在真空(kong)(kong)室充(chong)(chong)氣(qi)(qi)利用壓力(li)差(cha)(cha)充(chong)(chong)滿(man)袋(dai)(dai)子。可(ke)是(shi)(shi)客戶又要(yao)(yao)要(yao)(yao)求達到(dao)一(yi)定(ding)比(bi)例的(de)(de)(de)殘氧量，這(zhe)就很矛盾了。
