真空包裝(zhuang)機廠的(de)真空包裝機增(zeng)加充(chong)氣(qi)(qi)功能是(shi)有兩(liang)種(zhong)(zhong)(zhong)方(fang)式，一(yi)種(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)嘴直接伸(shen)到(dao)產品袋(dai)(dai)子(zi)(zi)里面進(jin)行充(chong)氣(qi)(qi)的(de)，另一(yi)種(zhong)(zhong)(zhong)是(shi)把要充(chong)的(de)氣(qi)(qi)體先充(chong)滿整個真空室，然后靠負壓差充(chong)滿袋(dai)(dai)子(zi)(zi)。那究竟采用(yong)哪種(zhong)(zhong)(zhong)方(fang)式充(chong)氣(qi)(qi)好(hao)(hao)呢，這里主要看(kan)客戶的(de)產品性(xing)質，單純來說肯定(ding)是(shi)直接沖到(dao)袋(dai)(dai)子(zi)(zi)里比較好(hao)(hao)，這樣置換的(de)又純還能省(sheng)不少氣(qi)(qi)源，但是(shi)大家一(yi)定(ding)要考(kao)慮好(hao)(hao)自(zi)己產品性(xing)質。如(ru)果產品是(shi)顆粒，我們(men)可以(yi)采取起(qi)初(chu)一(yi)種(zhong)(zhong)(zhong)方(fang)法直接讓充(chong)氣(qi)(qi)嘴到(dao)袋(dai)(dai)子(zi)(zi)里進(jin)行充(chong)氣(qi)(qi)，但是(shi)如(ru)果你的(de)產品是(shi)粉末(mo)狀的(de)就不能用(yong)起(qi)初(chu)一(yi)種(zhong)(zhong)(zhong)方(fang)法了(le)，需要第二種(zhong)(zhong)(zhong)在真空室充(chong)氣(qi)(qi)利用(yong)壓力差充(chong)滿袋(dai)(dai)子(zi)(zi)。可是(shi)客戶又要要求達到(dao)一(yi)定(ding)比例的(de)殘氧量(liang)，這就很矛盾了(le)。
