真空包(bao)裝(zhuang)機廠的(de)(de)(de)(de)真空包裝機(ji)增加充氣(qi)(qi)(qi)(qi)功(gong)能是(shi)有兩種(zhong)(zhong)(zhong)(zhong)方(fang)式，一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)(qi)(qi)嘴(zui)(zui)直(zhi)接伸到(dao)產(chan)品(pin)袋(dai)子(zi)里面進行充氣(qi)(qi)(qi)(qi)的(de)(de)(de)(de)，另一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)把要充的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體先充滿(man)整個真空室，然后靠負壓(ya)差充滿(man)袋(dai)子(zi)。那究竟采用哪種(zhong)(zhong)(zhong)(zhong)方(fang)式充氣(qi)(qi)(qi)(qi)好呢，這里主要看(kan)客(ke)戶的(de)(de)(de)(de)產(chan)品(pin)性(xing)質(zhi)，單純來(lai)說肯定是(shi)直(zhi)接沖到(dao)袋(dai)子(zi)里比較好，這樣置換的(de)(de)(de)(de)又(you)純還能省不少氣(qi)(qi)(qi)(qi)源，但(dan)是(shi)大家一(yi)定要考慮好自己產(chan)品(pin)性(xing)質(zhi)。如(ru)(ru)果(guo)產(chan)品(pin)是(shi)顆粒，我們可以(yi)采取起(qi)初一(yi)種(zhong)(zhong)(zhong)(zhong)方(fang)法(fa)直(zhi)接讓充氣(qi)(qi)(qi)(qi)嘴(zui)(zui)到(dao)袋(dai)子(zi)里進行充氣(qi)(qi)(qi)(qi)，但(dan)是(shi)如(ru)(ru)果(guo)你(ni)的(de)(de)(de)(de)產(chan)品(pin)是(shi)粉末狀的(de)(de)(de)(de)就(jiu)不能用起(qi)初一(yi)種(zhong)(zhong)(zhong)(zhong)方(fang)法(fa)了，需(xu)要第二種(zhong)(zhong)(zhong)(zhong)在真空室充氣(qi)(qi)(qi)(qi)利用壓(ya)力差充滿(man)袋(dai)子(zi)。可是(shi)客(ke)戶又(you)要要求達到(dao)一(yi)定比例(li)的(de)(de)(de)(de)殘(can)氧量(liang)，這就(jiu)很矛(mao)盾了。
