真空包裝機廠(chang)的(de)(de)(de)真空(kong)包裝機(ji)增加(jia)充(chong)(chong)(chong)(chong)(chong)氣功(gong)能(neng)(neng)是(shi)(shi)有兩種方(fang)式，一種是(shi)(shi)氣嘴直(zhi)接伸到產(chan)品袋(dai)子(zi)里面(mian)進行(xing)(xing)充(chong)(chong)(chong)(chong)(chong)氣的(de)(de)(de)，另一種是(shi)(shi)把要(yao)充(chong)(chong)(chong)(chong)(chong)的(de)(de)(de)氣體(ti)先充(chong)(chong)(chong)(chong)(chong)滿(man)(man)整個(ge)真空(kong)室(shi)(shi)，然后靠負壓差(cha)充(chong)(chong)(chong)(chong)(chong)滿(man)(man)袋(dai)子(zi)。那(nei)究竟采(cai)用哪種方(fang)式充(chong)(chong)(chong)(chong)(chong)氣好呢，這里主要(yao)看客(ke)戶(hu)的(de)(de)(de)產(chan)品性質，單純(chun)來說肯(ken)定是(shi)(shi)直(zhi)接沖到袋(dai)子(zi)里比較(jiao)好，這樣置換(huan)的(de)(de)(de)又(you)純(chun)還能(neng)(neng)省不(bu)少(shao)氣源，但(dan)是(shi)(shi)大家一定要(yao)考慮好自己產(chan)品性質。如果(guo)產(chan)品是(shi)(shi)顆(ke)粒(li)，我(wo)們可(ke)以采(cai)取起(qi)初(chu)一種方(fang)法(fa)直(zhi)接讓充(chong)(chong)(chong)(chong)(chong)氣嘴到袋(dai)子(zi)里進行(xing)(xing)充(chong)(chong)(chong)(chong)(chong)氣，但(dan)是(shi)(shi)如果(guo)你的(de)(de)(de)產(chan)品是(shi)(shi)粉(fen)末狀的(de)(de)(de)就(jiu)不(bu)能(neng)(neng)用起(qi)初(chu)一種方(fang)法(fa)了，需要(yao)第(di)二種在真空(kong)室(shi)(shi)充(chong)(chong)(chong)(chong)(chong)氣利用壓力差(cha)充(chong)(chong)(chong)(chong)(chong)滿(man)(man)袋(dai)子(zi)。可(ke)是(shi)(shi)客(ke)戶(hu)又(you)要(yao)要(yao)求達到一定比例的(de)(de)(de)殘氧量，這就(jiu)很矛盾(dun)了。
