真空(kong)包裝(zhuang)機廠的(de)真(zhen)空(kong)包裝機增加充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)功能(neng)(neng)是(shi)(shi)有兩種(zhong)(zhong)(zhong)方(fang)式，一種(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)(qi)(qi)(qi)嘴直接伸(shen)到(dao)(dao)產(chan)品(pin)袋(dai)(dai)子(zi)(zi)里(li)面進行(xing)充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)的(de)，另(ling)一種(zhong)(zhong)(zhong)是(shi)(shi)把要(yao)(yao)(yao)充(chong)(chong)(chong)的(de)氣(qi)(qi)(qi)(qi)體先充(chong)(chong)(chong)滿整(zheng)個真(zhen)空(kong)室，然后靠負壓(ya)差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。那(nei)究竟(jing)采用(yong)哪種(zhong)(zhong)(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)好呢(ni)，這里(li)主要(yao)(yao)(yao)看客(ke)戶(hu)的(de)產(chan)品(pin)性質(zhi)，單(dan)純來(lai)說肯定(ding)是(shi)(shi)直接沖到(dao)(dao)袋(dai)(dai)子(zi)(zi)里(li)比(bi)(bi)較好，這樣(yang)置(zhi)換的(de)又純還能(neng)(neng)省(sheng)不(bu)(bu)少氣(qi)(qi)(qi)(qi)源，但是(shi)(shi)大(da)家一定(ding)要(yao)(yao)(yao)考慮好自(zi)己(ji)產(chan)品(pin)性質(zhi)。如(ru)(ru)果產(chan)品(pin)是(shi)(shi)顆粒，我們可以采取起(qi)初一種(zhong)(zhong)(zhong)方(fang)法直接讓充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)嘴到(dao)(dao)袋(dai)(dai)子(zi)(zi)里(li)進行(xing)充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)，但是(shi)(shi)如(ru)(ru)果你的(de)產(chan)品(pin)是(shi)(shi)粉末狀的(de)就(jiu)不(bu)(bu)能(neng)(neng)用(yong)起(qi)初一種(zhong)(zhong)(zhong)方(fang)法了，需要(yao)(yao)(yao)第二種(zhong)(zhong)(zhong)在真(zhen)空(kong)室充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)利用(yong)壓(ya)力差充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。可是(shi)(shi)客(ke)戶(hu)又要(yao)(yao)(yao)要(yao)(yao)(yao)求達到(dao)(dao)一定(ding)比(bi)(bi)例的(de)殘氧量(liang)，這就(jiu)很矛盾了。
