真空包裝(zhuang)機廠的(de)真空(kong)(kong)包裝(zhuang)機(ji)增加充(chong)氣(qi)功(gong)能是(shi)(shi)有兩(liang)種(zhong)(zhong)(zhong)(zhong)方(fang)(fang)式(shi)，一種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)嘴(zui)直接(jie)伸到產(chan)品袋(dai)子里(li)面(mian)進行充(chong)氣(qi)的(de)，另一種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)把(ba)要(yao)充(chong)的(de)氣(qi)體先充(chong)滿整個真空(kong)(kong)室(shi)(shi)，然后靠負壓差充(chong)滿袋(dai)子。那究竟采(cai)用哪種(zhong)(zhong)(zhong)(zhong)方(fang)(fang)式(shi)充(chong)氣(qi)好(hao)呢，這(zhe)里(li)主要(yao)看客戶的(de)產(chan)品性質(zhi)，單純(chun)來說肯定是(shi)(shi)直接(jie)沖到袋(dai)子里(li)比(bi)較好(hao)，這(zhe)樣置換的(de)又純(chun)還能省不(bu)少氣(qi)源，但是(shi)(shi)大家一定要(yao)考(kao)慮好(hao)自己產(chan)品性質(zhi)。如果產(chan)品是(shi)(shi)顆粒，我們(men)可(ke)以采(cai)取起初(chu)一種(zhong)(zhong)(zhong)(zhong)方(fang)(fang)法(fa)直接(jie)讓充(chong)氣(qi)嘴(zui)到袋(dai)子里(li)進行充(chong)氣(qi)，但是(shi)(shi)如果你的(de)產(chan)品是(shi)(shi)粉(fen)末狀(zhuang)的(de)就不(bu)能用起初(chu)一種(zhong)(zhong)(zhong)(zhong)方(fang)(fang)法(fa)了，需要(yao)第二種(zhong)(zhong)(zhong)(zhong)在真空(kong)(kong)室(shi)(shi)充(chong)氣(qi)利用壓力差充(chong)滿袋(dai)子。可(ke)是(shi)(shi)客戶又要(yao)要(yao)求(qiu)達到一定比(bi)例的(de)殘氧量，這(zhe)就很矛盾了。
