真空包裝機廠的(de)(de)(de)真空(kong)包裝機增(zeng)加充(chong)(chong)氣(qi)(qi)(qi)(qi)功能(neng)是(shi)(shi)(shi)有兩種(zhong)(zhong)方(fang)(fang)式，一種(zhong)(zhong)是(shi)(shi)(shi)氣(qi)(qi)(qi)(qi)嘴直(zhi)接伸到(dao)(dao)產(chan)品(pin)袋(dai)子里(li)(li)面進行充(chong)(chong)氣(qi)(qi)(qi)(qi)的(de)(de)(de)，另一種(zhong)(zhong)是(shi)(shi)(shi)把要(yao)(yao)充(chong)(chong)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體先(xian)充(chong)(chong)滿(man)(man)(man)整個(ge)真空(kong)室，然后靠(kao)負壓差(cha)(cha)充(chong)(chong)滿(man)(man)(man)袋(dai)子。那究竟采用哪種(zhong)(zhong)方(fang)(fang)式充(chong)(chong)氣(qi)(qi)(qi)(qi)好(hao)(hao)呢，這里(li)(li)主(zhu)要(yao)(yao)看客戶(hu)的(de)(de)(de)產(chan)品(pin)性(xing)質(zhi)，單純來說(shuo)肯定(ding)是(shi)(shi)(shi)直(zhi)接沖到(dao)(dao)袋(dai)子里(li)(li)比(bi)較好(hao)(hao)，這樣置(zhi)換的(de)(de)(de)又純還能(neng)省不少(shao)氣(qi)(qi)(qi)(qi)源，但(dan)是(shi)(shi)(shi)大家(jia)一定(ding)要(yao)(yao)考慮好(hao)(hao)自己產(chan)品(pin)性(xing)質(zhi)。如(ru)果(guo)產(chan)品(pin)是(shi)(shi)(shi)顆粒，我(wo)們可以采取起初(chu)一種(zhong)(zhong)方(fang)(fang)法直(zhi)接讓充(chong)(chong)氣(qi)(qi)(qi)(qi)嘴到(dao)(dao)袋(dai)子里(li)(li)進行充(chong)(chong)氣(qi)(qi)(qi)(qi)，但(dan)是(shi)(shi)(shi)如(ru)果(guo)你的(de)(de)(de)產(chan)品(pin)是(shi)(shi)(shi)粉末狀的(de)(de)(de)就不能(neng)用起初(chu)一種(zhong)(zhong)方(fang)(fang)法了，需要(yao)(yao)第二種(zhong)(zhong)在真空(kong)室充(chong)(chong)氣(qi)(qi)(qi)(qi)利用壓力差(cha)(cha)充(chong)(chong)滿(man)(man)(man)袋(dai)子。可是(shi)(shi)(shi)客戶(hu)又要(yao)(yao)要(yao)(yao)求(qiu)達到(dao)(dao)一定(ding)比(bi)例的(de)(de)(de)殘氧(yang)量，這就很(hen)矛盾(dun)了。
