真空包裝機廠的(de)(de)真(zhen)(zhen)空(kong)包裝機增(zeng)加充(chong)氣(qi)(qi)功能是(shi)(shi)有兩種(zhong)(zhong)(zhong)(zhong)方(fang)(fang)式，一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)(qi)嘴直接伸(shen)到產(chan)(chan)(chan)(chan)品(pin)袋(dai)(dai)子(zi)里(li)面進行(xing)充(chong)氣(qi)(qi)的(de)(de)，另一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)把要充(chong)的(de)(de)氣(qi)(qi)體先(xian)充(chong)滿整個真(zhen)(zhen)空(kong)室，然后靠負壓差(cha)充(chong)滿袋(dai)(dai)子(zi)。那(nei)究(jiu)竟采(cai)用(yong)(yong)哪種(zhong)(zhong)(zhong)(zhong)方(fang)(fang)式充(chong)氣(qi)(qi)好呢，這(zhe)里(li)主要看(kan)客(ke)戶的(de)(de)產(chan)(chan)(chan)(chan)品(pin)性(xing)質，單純來說(shuo)肯定(ding)是(shi)(shi)直接沖到袋(dai)(dai)子(zi)里(li)比(bi)(bi)較好，這(zhe)樣(yang)置換(huan)的(de)(de)又純還能省不少氣(qi)(qi)源，但(dan)是(shi)(shi)大(da)家一(yi)定(ding)要考慮(lv)好自(zi)己產(chan)(chan)(chan)(chan)品(pin)性(xing)質。如果(guo)產(chan)(chan)(chan)(chan)品(pin)是(shi)(shi)顆粒，我們可以(yi)采(cai)取起初(chu)一(yi)種(zhong)(zhong)(zhong)(zhong)方(fang)(fang)法(fa)直接讓充(chong)氣(qi)(qi)嘴到袋(dai)(dai)子(zi)里(li)進行(xing)充(chong)氣(qi)(qi)，但(dan)是(shi)(shi)如果(guo)你的(de)(de)產(chan)(chan)(chan)(chan)品(pin)是(shi)(shi)粉末狀(zhuang)的(de)(de)就(jiu)不能用(yong)(yong)起初(chu)一(yi)種(zhong)(zhong)(zhong)(zhong)方(fang)(fang)法(fa)了，需要第二種(zhong)(zhong)(zhong)(zhong)在真(zhen)(zhen)空(kong)室充(chong)氣(qi)(qi)利用(yong)(yong)壓力(li)差(cha)充(chong)滿袋(dai)(dai)子(zi)。可是(shi)(shi)客(ke)戶又要要求達到一(yi)定(ding)比(bi)(bi)例的(de)(de)殘氧量，這(zhe)就(jiu)很矛盾了。
