真空包裝機廠的(de)真空包裝機增加充(chong)氣(qi)功能是(shi)(shi)有兩種(zhong)(zhong)(zhong)方式(shi)，一種(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)嘴(zui)直(zhi)接伸到(dao)(dao)(dao)產(chan)(chan)品(pin)袋(dai)子里(li)面進(jin)行充(chong)氣(qi)的(de)，另一種(zhong)(zhong)(zhong)是(shi)(shi)把要(yao)充(chong)的(de)氣(qi)體先充(chong)滿(man)(man)整個真空室，然后靠負壓差充(chong)滿(man)(man)袋(dai)子。那(nei)究(jiu)竟采用哪種(zhong)(zhong)(zhong)方式(shi)充(chong)氣(qi)好(hao)(hao)呢，這里(li)主要(yao)看(kan)客(ke)戶(hu)的(de)產(chan)(chan)品(pin)性(xing)質，單純(chun)來說(shuo)肯定是(shi)(shi)直(zhi)接沖到(dao)(dao)(dao)袋(dai)子里(li)比較好(hao)(hao)，這樣(yang)置換的(de)又純(chun)還(huan)能省不(bu)少(shao)氣(qi)源，但是(shi)(shi)大家(jia)一定要(yao)考慮好(hao)(hao)自己(ji)產(chan)(chan)品(pin)性(xing)質。如果產(chan)(chan)品(pin)是(shi)(shi)顆(ke)粒，我們可以采取起初(chu)一種(zhong)(zhong)(zhong)方法(fa)直(zhi)接讓充(chong)氣(qi)嘴(zui)到(dao)(dao)(dao)袋(dai)子里(li)進(jin)行充(chong)氣(qi)，但是(shi)(shi)如果你的(de)產(chan)(chan)品(pin)是(shi)(shi)粉(fen)末狀的(de)就(jiu)不(bu)能用起初(chu)一種(zhong)(zhong)(zhong)方法(fa)了，需要(yao)第二種(zhong)(zhong)(zhong)在真空室充(chong)氣(qi)利用壓力(li)差充(chong)滿(man)(man)袋(dai)子。可是(shi)(shi)客(ke)戶(hu)又要(yao)要(yao)求達到(dao)(dao)(dao)一定比例的(de)殘氧(yang)量，這就(jiu)很矛盾(dun)了。
