真空(kong)包裝機廠的(de)真空(kong)包(bao)裝(zhuang)機增加(jia)充(chong)(chong)氣(qi)功能是(shi)(shi)(shi)有兩種方(fang)式，一(yi)種是(shi)(shi)(shi)氣(qi)嘴直接(jie)伸到(dao)(dao)(dao)產(chan)(chan)(chan)品(pin)袋(dai)子(zi)(zi)(zi)里(li)(li)(li)面進行充(chong)(chong)氣(qi)的(de)，另(ling)一(yi)種是(shi)(shi)(shi)把(ba)要(yao)(yao)(yao)充(chong)(chong)的(de)氣(qi)體先充(chong)(chong)滿整個真空(kong)室，然后靠負壓(ya)(ya)差(cha)充(chong)(chong)滿袋(dai)子(zi)(zi)(zi)。那究竟(jing)采用(yong)(yong)哪種方(fang)式充(chong)(chong)氣(qi)好呢，這(zhe)里(li)(li)(li)主要(yao)(yao)(yao)看客(ke)戶(hu)的(de)產(chan)(chan)(chan)品(pin)性(xing)質，單純(chun)(chun)來說肯定(ding)是(shi)(shi)(shi)直接(jie)沖到(dao)(dao)(dao)袋(dai)子(zi)(zi)(zi)里(li)(li)(li)比較好，這(zhe)樣置(zhi)換的(de)又純(chun)(chun)還能省不少氣(qi)源，但是(shi)(shi)(shi)大家一(yi)定(ding)要(yao)(yao)(yao)考慮好自己產(chan)(chan)(chan)品(pin)性(xing)質。如(ru)果(guo)產(chan)(chan)(chan)品(pin)是(shi)(shi)(shi)顆粒，我(wo)們可以采取起初(chu)一(yi)種方(fang)法直接(jie)讓充(chong)(chong)氣(qi)嘴到(dao)(dao)(dao)袋(dai)子(zi)(zi)(zi)里(li)(li)(li)進行充(chong)(chong)氣(qi)，但是(shi)(shi)(shi)如(ru)果(guo)你的(de)產(chan)(chan)(chan)品(pin)是(shi)(shi)(shi)粉末狀的(de)就不能用(yong)(yong)起初(chu)一(yi)種方(fang)法了(le)，需(xu)要(yao)(yao)(yao)第二種在真空(kong)室充(chong)(chong)氣(qi)利用(yong)(yong)壓(ya)(ya)力差(cha)充(chong)(chong)滿袋(dai)子(zi)(zi)(zi)。可是(shi)(shi)(shi)客(ke)戶(hu)又要(yao)(yao)(yao)要(yao)(yao)(yao)求達(da)到(dao)(dao)(dao)一(yi)定(ding)比例(li)的(de)殘氧量(liang)，這(zhe)就很矛(mao)盾了(le)。
