真空包裝機廠的(de)真空包(bao)裝機增加(jia)充氣(qi)功能(neng)(neng)是(shi)(shi)(shi)有兩(liang)種(zhong)(zhong)(zhong)方(fang)式，一種(zhong)(zhong)(zhong)是(shi)(shi)(shi)氣(qi)嘴直(zhi)(zhi)接(jie)伸到(dao)產(chan)(chan)品(pin)袋子(zi)里面進(jin)行(xing)充氣(qi)的(de)，另一種(zhong)(zhong)(zhong)是(shi)(shi)(shi)把要充的(de)氣(qi)體(ti)先充滿(man)(man)整個真空室(shi)，然(ran)后靠(kao)負壓差充滿(man)(man)袋子(zi)。那究(jiu)竟采用哪種(zhong)(zhong)(zhong)方(fang)式充氣(qi)好呢，這里主(zhu)要看客(ke)戶(hu)的(de)產(chan)(chan)品(pin)性(xing)質，單(dan)純來說肯(ken)定是(shi)(shi)(shi)直(zhi)(zhi)接(jie)沖(chong)到(dao)袋子(zi)里比(bi)較(jiao)好，這樣置(zhi)換的(de)又純還能(neng)(neng)省(sheng)不少氣(qi)源，但(dan)(dan)是(shi)(shi)(shi)大家(jia)一定要考(kao)慮好自(zi)己產(chan)(chan)品(pin)性(xing)質。如(ru)果產(chan)(chan)品(pin)是(shi)(shi)(shi)顆(ke)粒，我們可以(yi)采取起初一種(zhong)(zhong)(zhong)方(fang)法直(zhi)(zhi)接(jie)讓充氣(qi)嘴到(dao)袋子(zi)里進(jin)行(xing)充氣(qi)，但(dan)(dan)是(shi)(shi)(shi)如(ru)果你的(de)產(chan)(chan)品(pin)是(shi)(shi)(shi)粉(fen)末狀的(de)就(jiu)不能(neng)(neng)用起初一種(zhong)(zhong)(zhong)方(fang)法了(le)，需要第二種(zhong)(zhong)(zhong)在(zai)真空室(shi)充氣(qi)利(li)用壓力差充滿(man)(man)袋子(zi)。可是(shi)(shi)(shi)客(ke)戶(hu)又要要求達到(dao)一定比(bi)例的(de)殘氧量，這就(jiu)很矛(mao)盾了(le)。
