真空(kong)包裝機廠的(de)(de)(de)真(zhen)空(kong)包裝機增加充(chong)(chong)氣(qi)(qi)功能是(shi)有兩種(zhong)(zhong)方式(shi)，一種(zhong)(zhong)是(shi)氣(qi)(qi)嘴(zui)直(zhi)(zhi)接伸到(dao)產(chan)品(pin)袋(dai)(dai)子(zi)里面進行充(chong)(chong)氣(qi)(qi)的(de)(de)(de)，另一種(zhong)(zhong)是(shi)把(ba)要充(chong)(chong)的(de)(de)(de)氣(qi)(qi)體先充(chong)(chong)滿整個真(zhen)空(kong)室(shi)，然后靠負壓差(cha)充(chong)(chong)滿袋(dai)(dai)子(zi)。那(nei)究竟采用哪種(zhong)(zhong)方式(shi)充(chong)(chong)氣(qi)(qi)好呢，這里主(zhu)要看客戶(hu)的(de)(de)(de)產(chan)品(pin)性質，單純(chun)來(lai)說肯(ken)定是(shi)直(zhi)(zhi)接沖到(dao)袋(dai)(dai)子(zi)里比較好，這樣置(zhi)換的(de)(de)(de)又純(chun)還能省不少(shao)氣(qi)(qi)源，但是(shi)大(da)家一定要考慮好自(zi)己產(chan)品(pin)性質。如(ru)果(guo)產(chan)品(pin)是(shi)顆粒，我們(men)可以采取起初一種(zhong)(zhong)方法直(zhi)(zhi)接讓充(chong)(chong)氣(qi)(qi)嘴(zui)到(dao)袋(dai)(dai)子(zi)里進行充(chong)(chong)氣(qi)(qi)，但是(shi)如(ru)果(guo)你的(de)(de)(de)產(chan)品(pin)是(shi)粉末狀的(de)(de)(de)就(jiu)不能用起初一種(zhong)(zhong)方法了(le)，需(xu)要第二種(zhong)(zhong)在真(zhen)空(kong)室(shi)充(chong)(chong)氣(qi)(qi)利用壓力差(cha)充(chong)(chong)滿袋(dai)(dai)子(zi)。可是(shi)客戶(hu)又要要求達到(dao)一定比例的(de)(de)(de)殘氧量，這就(jiu)很(hen)矛(mao)盾了(le)。
