真空包(bao)裝機廠的(de)(de)(de)(de)真(zhen)空(kong)包裝(zhuang)機(ji)增加充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)功(gong)能是(shi)(shi)有兩種(zhong)(zhong)方(fang)式，一(yi)種(zhong)(zhong)是(shi)(shi)氣(qi)(qi)(qi)(qi)嘴直接伸到(dao)產品袋(dai)子里(li)面進行充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)的(de)(de)(de)(de)，另一(yi)種(zhong)(zhong)是(shi)(shi)把(ba)要充(chong)(chong)(chong)的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體先充(chong)(chong)(chong)滿(man)整個(ge)真(zhen)空(kong)室，然后(hou)靠負(fu)壓(ya)差(cha)充(chong)(chong)(chong)滿(man)袋(dai)子。那究竟采(cai)用(yong)哪種(zhong)(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)好呢，這里(li)主要看客戶的(de)(de)(de)(de)產品性(xing)質(zhi)，單純(chun)來說(shuo)肯(ken)定(ding)是(shi)(shi)直接沖到(dao)袋(dai)子里(li)比較好，這樣(yang)置換的(de)(de)(de)(de)又純(chun)還(huan)能省不(bu)少氣(qi)(qi)(qi)(qi)源，但是(shi)(shi)大家(jia)一(yi)定(ding)要考慮好自己(ji)產品性(xing)質(zhi)。如果(guo)產品是(shi)(shi)顆粒，我們可以(yi)采(cai)取起(qi)初一(yi)種(zhong)(zhong)方(fang)法直接讓(rang)充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)嘴到(dao)袋(dai)子里(li)進行充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)，但是(shi)(shi)如果(guo)你的(de)(de)(de)(de)產品是(shi)(shi)粉末狀的(de)(de)(de)(de)就不(bu)能用(yong)起(qi)初一(yi)種(zhong)(zhong)方(fang)法了(le)，需要第(di)二種(zhong)(zhong)在(zai)真(zhen)空(kong)室充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)利用(yong)壓(ya)力差(cha)充(chong)(chong)(chong)滿(man)袋(dai)子。可是(shi)(shi)客戶又要要求達到(dao)一(yi)定(ding)比例的(de)(de)(de)(de)殘氧量，這就很矛(mao)盾了(le)。
