真(zhen)空包裝(zhuang)機廠的(de)(de)真空(kong)包裝機增加充(chong)(chong)(chong)(chong)氣(qi)功(gong)能是(shi)(shi)有兩種方(fang)式，一(yi)(yi)(yi)(yi)種是(shi)(shi)氣(qi)嘴直接(jie)伸(shen)到(dao)產(chan)品袋(dai)(dai)(dai)(dai)子里(li)面進行(xing)(xing)充(chong)(chong)(chong)(chong)氣(qi)的(de)(de)，另(ling)一(yi)(yi)(yi)(yi)種是(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)(chong)的(de)(de)氣(qi)體先充(chong)(chong)(chong)(chong)滿整個真空(kong)室(shi)，然(ran)后靠負壓(ya)差充(chong)(chong)(chong)(chong)滿袋(dai)(dai)(dai)(dai)子。那(nei)究竟采(cai)用哪種方(fang)式充(chong)(chong)(chong)(chong)氣(qi)好呢，這(zhe)里(li)主要(yao)(yao)看客戶(hu)的(de)(de)產(chan)品性質(zhi)，單純來說(shuo)肯(ken)定(ding)是(shi)(shi)直接(jie)沖(chong)到(dao)袋(dai)(dai)(dai)(dai)子里(li)比(bi)較好，這(zhe)樣(yang)置換的(de)(de)又純還能省不少氣(qi)源，但是(shi)(shi)大家(jia)一(yi)(yi)(yi)(yi)定(ding)要(yao)(yao)考(kao)慮(lv)好自己(ji)產(chan)品性質(zhi)。如果(guo)產(chan)品是(shi)(shi)顆粒，我(wo)們可(ke)以采(cai)取(qu)起初一(yi)(yi)(yi)(yi)種方(fang)法直接(jie)讓充(chong)(chong)(chong)(chong)氣(qi)嘴到(dao)袋(dai)(dai)(dai)(dai)子里(li)進行(xing)(xing)充(chong)(chong)(chong)(chong)氣(qi)，但是(shi)(shi)如果(guo)你的(de)(de)產(chan)品是(shi)(shi)粉末狀的(de)(de)就不能用起初一(yi)(yi)(yi)(yi)種方(fang)法了，需要(yao)(yao)第二種在真空(kong)室(shi)充(chong)(chong)(chong)(chong)氣(qi)利用壓(ya)力差充(chong)(chong)(chong)(chong)滿袋(dai)(dai)(dai)(dai)子。可(ke)是(shi)(shi)客戶(hu)又要(yao)(yao)要(yao)(yao)求達(da)到(dao)一(yi)(yi)(yi)(yi)定(ding)比(bi)例(li)的(de)(de)殘氧量，這(zhe)就很矛盾了。
