真空包裝機廠的(de)(de)真(zhen)(zhen)空(kong)包裝機(ji)增加充(chong)(chong)(chong)氣(qi)功能是(shi)(shi)有兩種(zhong)(zhong)方(fang)式(shi)，一(yi)種(zhong)(zhong)是(shi)(shi)氣(qi)嘴(zui)直(zhi)接(jie)伸(shen)到產(chan)品袋(dai)子(zi)(zi)里(li)(li)面(mian)進行充(chong)(chong)(chong)氣(qi)的(de)(de)，另一(yi)種(zhong)(zhong)是(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)的(de)(de)氣(qi)體(ti)先(xian)充(chong)(chong)(chong)滿(man)整(zheng)個真(zhen)(zhen)空(kong)室(shi)，然(ran)后靠(kao)負壓差充(chong)(chong)(chong)滿(man)袋(dai)子(zi)(zi)。那(nei)究竟采用(yong)哪種(zhong)(zhong)方(fang)式(shi)充(chong)(chong)(chong)氣(qi)好呢，這里(li)(li)主(zhu)要(yao)(yao)看(kan)客戶的(de)(de)產(chan)品性質(zhi)，單純(chun)來說肯定是(shi)(shi)直(zhi)接(jie)沖到袋(dai)子(zi)(zi)里(li)(li)比(bi)(bi)較好，這樣置換的(de)(de)又純(chun)還能省不(bu)少氣(qi)源(yuan)，但(dan)是(shi)(shi)大家一(yi)定要(yao)(yao)考慮好自(zi)己產(chan)品性質(zhi)。如果產(chan)品是(shi)(shi)顆粒，我們可以(yi)采取起(qi)初一(yi)種(zhong)(zhong)方(fang)法直(zhi)接(jie)讓(rang)充(chong)(chong)(chong)氣(qi)嘴(zui)到袋(dai)子(zi)(zi)里(li)(li)進行充(chong)(chong)(chong)氣(qi)，但(dan)是(shi)(shi)如果你的(de)(de)產(chan)品是(shi)(shi)粉末狀(zhuang)的(de)(de)就不(bu)能用(yong)起(qi)初一(yi)種(zhong)(zhong)方(fang)法了，需要(yao)(yao)第二(er)種(zhong)(zhong)在真(zhen)(zhen)空(kong)室(shi)充(chong)(chong)(chong)氣(qi)利用(yong)壓力差充(chong)(chong)(chong)滿(man)袋(dai)子(zi)(zi)。可是(shi)(shi)客戶又要(yao)(yao)要(yao)(yao)求達到一(yi)定比(bi)(bi)例的(de)(de)殘氧(yang)量，這就很矛盾了。
