真空包(bao)裝機廠的(de)真空包裝機增加充(chong)氣(qi)(qi)(qi)功能是(shi)(shi)(shi)有兩種(zhong)(zhong)(zhong)方(fang)式(shi)，一(yi)種(zhong)(zhong)(zhong)是(shi)(shi)(shi)氣(qi)(qi)(qi)嘴直接伸到(dao)產(chan)品(pin)袋(dai)子里(li)(li)(li)面進(jin)行充(chong)氣(qi)(qi)(qi)的(de)，另一(yi)種(zhong)(zhong)(zhong)是(shi)(shi)(shi)把要充(chong)的(de)氣(qi)(qi)(qi)體先充(chong)滿(man)整個(ge)真空室，然后靠負壓差(cha)(cha)充(chong)滿(man)袋(dai)子。那究竟采(cai)用(yong)(yong)哪種(zhong)(zhong)(zhong)方(fang)式(shi)充(chong)氣(qi)(qi)(qi)好(hao)呢，這里(li)(li)(li)主要看客(ke)戶的(de)產(chan)品(pin)性質，單純來說肯定(ding)是(shi)(shi)(shi)直接沖到(dao)袋(dai)子里(li)(li)(li)比(bi)較好(hao)，這樣置換的(de)又純還能省(sheng)不少氣(qi)(qi)(qi)源，但(dan)是(shi)(shi)(shi)大家一(yi)定(ding)要考慮(lv)好(hao)自己產(chan)品(pin)性質。如(ru)果產(chan)品(pin)是(shi)(shi)(shi)顆粒，我們可以采(cai)取起(qi)初一(yi)種(zhong)(zhong)(zhong)方(fang)法直接讓充(chong)氣(qi)(qi)(qi)嘴到(dao)袋(dai)子里(li)(li)(li)進(jin)行充(chong)氣(qi)(qi)(qi)，但(dan)是(shi)(shi)(shi)如(ru)果你的(de)產(chan)品(pin)是(shi)(shi)(shi)粉末狀的(de)就(jiu)不能用(yong)(yong)起(qi)初一(yi)種(zhong)(zhong)(zhong)方(fang)法了，需要第二種(zhong)(zhong)(zhong)在真空室充(chong)氣(qi)(qi)(qi)利(li)用(yong)(yong)壓力差(cha)(cha)充(chong)滿(man)袋(dai)子。可是(shi)(shi)(shi)客(ke)戶又要要求達到(dao)一(yi)定(ding)比(bi)例的(de)殘氧量，這就(jiu)很矛盾(dun)了。
