真空(kong)包裝機廠(chang)的(de)(de)真空(kong)包裝機增加充(chong)(chong)氣(qi)(qi)功(gong)能(neng)是(shi)(shi)(shi)有兩種方式，一(yi)種是(shi)(shi)(shi)氣(qi)(qi)嘴直接伸到(dao)(dao)產(chan)(chan)品(pin)袋(dai)(dai)子里面進行充(chong)(chong)氣(qi)(qi)的(de)(de)，另一(yi)種是(shi)(shi)(shi)把(ba)要充(chong)(chong)的(de)(de)氣(qi)(qi)體先充(chong)(chong)滿整(zheng)個真空(kong)室(shi)，然后靠負(fu)壓差(cha)充(chong)(chong)滿袋(dai)(dai)子。那究(jiu)竟(jing)采用哪種方式充(chong)(chong)氣(qi)(qi)好呢，這里主要看(kan)客戶(hu)的(de)(de)產(chan)(chan)品(pin)性質(zhi)，單純來說(shuo)肯定(ding)是(shi)(shi)(shi)直接沖到(dao)(dao)袋(dai)(dai)子里比較好，這樣置換的(de)(de)又純還能(neng)省(sheng)不少氣(qi)(qi)源，但是(shi)(shi)(shi)大家一(yi)定(ding)要考慮(lv)好自己產(chan)(chan)品(pin)性質(zhi)。如果(guo)產(chan)(chan)品(pin)是(shi)(shi)(shi)顆(ke)粒，我們可以采取(qu)起初一(yi)種方法直接讓充(chong)(chong)氣(qi)(qi)嘴到(dao)(dao)袋(dai)(dai)子里進行充(chong)(chong)氣(qi)(qi)，但是(shi)(shi)(shi)如果(guo)你(ni)的(de)(de)產(chan)(chan)品(pin)是(shi)(shi)(shi)粉末狀的(de)(de)就(jiu)不能(neng)用起初一(yi)種方法了，需要第二種在真空(kong)室(shi)充(chong)(chong)氣(qi)(qi)利用壓力差(cha)充(chong)(chong)滿袋(dai)(dai)子。可是(shi)(shi)(shi)客戶(hu)又要要求達到(dao)(dao)一(yi)定(ding)比例的(de)(de)殘氧量，這就(jiu)很矛(mao)盾了。
