真空包裝機廠的(de)真(zhen)空包裝(zhuang)機增(zeng)加充(chong)(chong)(chong)(chong)氣(qi)功能是(shi)(shi)有(you)兩種(zhong)方(fang)式，一(yi)種(zhong)是(shi)(shi)氣(qi)嘴(zui)直接(jie)伸到產品(pin)(pin)(pin)袋(dai)(dai)子(zi)里(li)面進(jin)行(xing)充(chong)(chong)(chong)(chong)氣(qi)的(de)，另(ling)一(yi)種(zhong)是(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)(chong)的(de)氣(qi)體先充(chong)(chong)(chong)(chong)滿(man)整個真(zhen)空室，然后靠負(fu)壓(ya)(ya)差充(chong)(chong)(chong)(chong)滿(man)袋(dai)(dai)子(zi)。那(nei)究竟采用(yong)(yong)哪種(zhong)方(fang)式充(chong)(chong)(chong)(chong)氣(qi)好呢，這里(li)主要(yao)(yao)看客戶的(de)產品(pin)(pin)(pin)性(xing)質，單(dan)純來說肯(ken)定(ding)是(shi)(shi)直接(jie)沖到袋(dai)(dai)子(zi)里(li)比(bi)(bi)較好，這樣置換的(de)又純還能省不少氣(qi)源(yuan)，但是(shi)(shi)大(da)家一(yi)定(ding)要(yao)(yao)考慮好自己產品(pin)(pin)(pin)性(xing)質。如(ru)果產品(pin)(pin)(pin)是(shi)(shi)顆(ke)粒，我們可以采取起初一(yi)種(zhong)方(fang)法(fa)直接(jie)讓充(chong)(chong)(chong)(chong)氣(qi)嘴(zui)到袋(dai)(dai)子(zi)里(li)進(jin)行(xing)充(chong)(chong)(chong)(chong)氣(qi)，但是(shi)(shi)如(ru)果你的(de)產品(pin)(pin)(pin)是(shi)(shi)粉末狀的(de)就(jiu)不能用(yong)(yong)起初一(yi)種(zhong)方(fang)法(fa)了，需要(yao)(yao)第二種(zhong)在真(zhen)空室充(chong)(chong)(chong)(chong)氣(qi)利用(yong)(yong)壓(ya)(ya)力差充(chong)(chong)(chong)(chong)滿(man)袋(dai)(dai)子(zi)。可是(shi)(shi)客戶又要(yao)(yao)要(yao)(yao)求達到一(yi)定(ding)比(bi)(bi)例的(de)殘(can)氧量，這就(jiu)很(hen)矛盾了。
