真空(kong)包(bao)裝機廠的(de)(de)(de)(de)真空(kong)(kong)包裝機(ji)增(zeng)加充(chong)氣(qi)(qi)(qi)功能(neng)是(shi)(shi)(shi)有兩種(zhong)(zhong)方式(shi)，一(yi)(yi)(yi)種(zhong)(zhong)是(shi)(shi)(shi)氣(qi)(qi)(qi)嘴直(zhi)接伸到產(chan)品(pin)袋(dai)(dai)子(zi)里面進(jin)行(xing)充(chong)氣(qi)(qi)(qi)的(de)(de)(de)(de)，另一(yi)(yi)(yi)種(zhong)(zhong)是(shi)(shi)(shi)把要(yao)充(chong)的(de)(de)(de)(de)氣(qi)(qi)(qi)體先充(chong)滿(man)(man)整(zheng)個(ge)真空(kong)(kong)室，然后(hou)靠負壓差充(chong)滿(man)(man)袋(dai)(dai)子(zi)。那究(jiu)竟采用(yong)哪(na)種(zhong)(zhong)方式(shi)充(chong)氣(qi)(qi)(qi)好(hao)呢，這(zhe)里主要(yao)看客戶的(de)(de)(de)(de)產(chan)品(pin)性(xing)質，單純來說肯定是(shi)(shi)(shi)直(zhi)接沖到袋(dai)(dai)子(zi)里比較好(hao)，這(zhe)樣置(zhi)換(huan)的(de)(de)(de)(de)又純還能(neng)省不少氣(qi)(qi)(qi)源，但是(shi)(shi)(shi)大家一(yi)(yi)(yi)定要(yao)考慮好(hao)自(zi)己產(chan)品(pin)性(xing)質。如(ru)果(guo)產(chan)品(pin)是(shi)(shi)(shi)顆粒(li)，我(wo)們可以采取起初一(yi)(yi)(yi)種(zhong)(zhong)方法直(zhi)接讓(rang)充(chong)氣(qi)(qi)(qi)嘴到袋(dai)(dai)子(zi)里進(jin)行(xing)充(chong)氣(qi)(qi)(qi)，但是(shi)(shi)(shi)如(ru)果(guo)你的(de)(de)(de)(de)產(chan)品(pin)是(shi)(shi)(shi)粉(fen)末狀(zhuang)的(de)(de)(de)(de)就(jiu)不能(neng)用(yong)起初一(yi)(yi)(yi)種(zhong)(zhong)方法了，需(xu)要(yao)第二種(zhong)(zhong)在(zai)真空(kong)(kong)室充(chong)氣(qi)(qi)(qi)利用(yong)壓力差充(chong)滿(man)(man)袋(dai)(dai)子(zi)。可是(shi)(shi)(shi)客戶又要(yao)要(yao)求(qiu)達到一(yi)(yi)(yi)定比例的(de)(de)(de)(de)殘氧量，這(zhe)就(jiu)很矛(mao)盾(dun)了。
