真(zhen)空包裝機廠的(de)真空(kong)包(bao)裝機增加充(chong)氣(qi)功能(neng)是(shi)(shi)有兩(liang)種(zhong)(zhong)方(fang)式，一種(zhong)(zhong)是(shi)(shi)氣(qi)嘴直接(jie)伸到(dao)(dao)產(chan)(chan)品袋(dai)子(zi)里(li)面進行充(chong)氣(qi)的(de)，另一種(zhong)(zhong)是(shi)(shi)把要(yao)充(chong)的(de)氣(qi)體(ti)先充(chong)滿(man)整個真空(kong)室，然后靠負壓差充(chong)滿(man)袋(dai)子(zi)。那究竟采(cai)用(yong)哪種(zhong)(zhong)方(fang)式充(chong)氣(qi)好(hao)呢，這(zhe)里(li)主要(yao)看客戶的(de)產(chan)(chan)品性質，單純來說肯定(ding)是(shi)(shi)直接(jie)沖到(dao)(dao)袋(dai)子(zi)里(li)比(bi)(bi)較好(hao)，這(zhe)樣(yang)置換(huan)的(de)又純還能(neng)省不(bu)少氣(qi)源，但是(shi)(shi)大家(jia)一定(ding)要(yao)考慮好(hao)自己產(chan)(chan)品性質。如(ru)果產(chan)(chan)品是(shi)(shi)顆粒，我們(men)可(ke)以采(cai)取(qu)起初一種(zhong)(zhong)方(fang)法直接(jie)讓充(chong)氣(qi)嘴到(dao)(dao)袋(dai)子(zi)里(li)進行充(chong)氣(qi)，但是(shi)(shi)如(ru)果你的(de)產(chan)(chan)品是(shi)(shi)粉(fen)末狀的(de)就(jiu)(jiu)不(bu)能(neng)用(yong)起初一種(zhong)(zhong)方(fang)法了(le)，需要(yao)第(di)二種(zhong)(zhong)在真空(kong)室充(chong)氣(qi)利用(yong)壓力差充(chong)滿(man)袋(dai)子(zi)。可(ke)是(shi)(shi)客戶又要(yao)要(yao)求達到(dao)(dao)一定(ding)比(bi)(bi)例的(de)殘(can)氧量，這(zhe)就(jiu)(jiu)很(hen)矛盾了(le)。
