真空包裝機廠的真空(kong)包裝(zhuang)機增加充(chong)(chong)氣(qi)功能(neng)是(shi)(shi)(shi)有兩種方(fang)(fang)式，一(yi)種是(shi)(shi)(shi)氣(qi)嘴直接伸到產品(pin)袋(dai)子里(li)(li)面(mian)進行(xing)充(chong)(chong)氣(qi)的，另一(yi)種是(shi)(shi)(shi)把(ba)要(yao)(yao)充(chong)(chong)的氣(qi)體先充(chong)(chong)滿(man)(man)整個(ge)真空(kong)室，然后靠負壓差充(chong)(chong)滿(man)(man)袋(dai)子。那(nei)究竟采用哪種方(fang)(fang)式充(chong)(chong)氣(qi)好呢，這(zhe)里(li)(li)主要(yao)(yao)看(kan)客戶(hu)的產品(pin)性質，單純(chun)來說肯(ken)定(ding)是(shi)(shi)(shi)直接沖到袋(dai)子里(li)(li)比較好，這(zhe)樣(yang)置換的又純(chun)還能(neng)省不少(shao)氣(qi)源，但是(shi)(shi)(shi)大家一(yi)定(ding)要(yao)(yao)考慮好自己產品(pin)性質。如(ru)果產品(pin)是(shi)(shi)(shi)顆粒，我(wo)們可以采取起初一(yi)種方(fang)(fang)法直接讓(rang)充(chong)(chong)氣(qi)嘴到袋(dai)子里(li)(li)進行(xing)充(chong)(chong)氣(qi)，但是(shi)(shi)(shi)如(ru)果你(ni)的產品(pin)是(shi)(shi)(shi)粉末狀(zhuang)的就(jiu)不能(neng)用起初一(yi)種方(fang)(fang)法了，需(xu)要(yao)(yao)第二種在真空(kong)室充(chong)(chong)氣(qi)利用壓力差充(chong)(chong)滿(man)(man)袋(dai)子。可是(shi)(shi)(shi)客戶(hu)又要(yao)(yao)要(yao)(yao)求達到一(yi)定(ding)比例(li)的殘氧量(liang)，這(zhe)就(jiu)很矛(mao)盾了。
