真空(kong)包裝(zhuang)機廠的(de)真空(kong)包裝機(ji)增加充(chong)(chong)(chong)(chong)氣(qi)(qi)功(gong)能(neng)是(shi)有兩種(zhong)方式，一種(zhong)是(shi)氣(qi)(qi)嘴(zui)直接伸到(dao)(dao)產(chan)品袋(dai)子(zi)里(li)面進行(xing)充(chong)(chong)(chong)(chong)氣(qi)(qi)的(de)，另一種(zhong)是(shi)把要(yao)(yao)充(chong)(chong)(chong)(chong)的(de)氣(qi)(qi)體先充(chong)(chong)(chong)(chong)滿整(zheng)個真空(kong)室，然后靠負壓差充(chong)(chong)(chong)(chong)滿袋(dai)子(zi)。那究竟(jing)采用哪(na)種(zhong)方式充(chong)(chong)(chong)(chong)氣(qi)(qi)好(hao)呢(ni)，這(zhe)(zhe)里(li)主要(yao)(yao)看(kan)客(ke)戶的(de)產(chan)品性質(zhi)(zhi)，單純(chun)來說肯定(ding)是(shi)直接沖到(dao)(dao)袋(dai)子(zi)里(li)比(bi)較好(hao)，這(zhe)(zhe)樣(yang)置換的(de)又(you)純(chun)還能(neng)省不少氣(qi)(qi)源，但(dan)是(shi)大家(jia)一定(ding)要(yao)(yao)考(kao)慮(lv)好(hao)自己(ji)產(chan)品性質(zhi)(zhi)。如果(guo)產(chan)品是(shi)顆粒，我們(men)可以(yi)采取(qu)起(qi)(qi)初一種(zhong)方法直接讓充(chong)(chong)(chong)(chong)氣(qi)(qi)嘴(zui)到(dao)(dao)袋(dai)子(zi)里(li)進行(xing)充(chong)(chong)(chong)(chong)氣(qi)(qi)，但(dan)是(shi)如果(guo)你的(de)產(chan)品是(shi)粉末(mo)狀的(de)就不能(neng)用起(qi)(qi)初一種(zhong)方法了(le)，需要(yao)(yao)第(di)二種(zhong)在真空(kong)室充(chong)(chong)(chong)(chong)氣(qi)(qi)利用壓力差充(chong)(chong)(chong)(chong)滿袋(dai)子(zi)。可是(shi)客(ke)戶又(you)要(yao)(yao)要(yao)(yao)求(qiu)達到(dao)(dao)一定(ding)比(bi)例的(de)殘(can)氧量(liang)，這(zhe)(zhe)就很矛盾了(le)。
