真空包裝機(ji)廠的(de)(de)真空包裝機增加充(chong)氣(qi)(qi)功能(neng)(neng)(neng)是(shi)(shi)(shi)有(you)兩種(zhong)(zhong)方式，一(yi)種(zhong)(zhong)是(shi)(shi)(shi)氣(qi)(qi)嘴(zui)直(zhi)接(jie)伸(shen)到(dao)(dao)產(chan)品(pin)(pin)袋(dai)子(zi)(zi)里(li)面進(jin)行充(chong)氣(qi)(qi)的(de)(de)，另一(yi)種(zhong)(zhong)是(shi)(shi)(shi)把要(yao)充(chong)的(de)(de)氣(qi)(qi)體先充(chong)滿整(zheng)個真空室(shi)，然后靠(kao)負壓差充(chong)滿袋(dai)子(zi)(zi)。那究(jiu)竟采用(yong)哪種(zhong)(zhong)方式充(chong)氣(qi)(qi)好(hao)呢，這(zhe)里(li)主(zhu)要(yao)看客戶(hu)的(de)(de)產(chan)品(pin)(pin)性質(zhi)，單純來說肯定是(shi)(shi)(shi)直(zhi)接(jie)沖(chong)到(dao)(dao)袋(dai)子(zi)(zi)里(li)比較(jiao)好(hao)，這(zhe)樣置換的(de)(de)又純還能(neng)(neng)(neng)省不(bu)少氣(qi)(qi)源，但是(shi)(shi)(shi)大家一(yi)定要(yao)考(kao)慮好(hao)自己產(chan)品(pin)(pin)性質(zhi)。如果(guo)產(chan)品(pin)(pin)是(shi)(shi)(shi)顆(ke)粒，我們可以(yi)采取起初(chu)一(yi)種(zhong)(zhong)方法(fa)直(zhi)接(jie)讓充(chong)氣(qi)(qi)嘴(zui)到(dao)(dao)袋(dai)子(zi)(zi)里(li)進(jin)行充(chong)氣(qi)(qi)，但是(shi)(shi)(shi)如果(guo)你(ni)的(de)(de)產(chan)品(pin)(pin)是(shi)(shi)(shi)粉末狀的(de)(de)就(jiu)不(bu)能(neng)(neng)(neng)用(yong)起初(chu)一(yi)種(zhong)(zhong)方法(fa)了，需要(yao)第二(er)種(zhong)(zhong)在真空室(shi)充(chong)氣(qi)(qi)利用(yong)壓力差充(chong)滿袋(dai)子(zi)(zi)。可是(shi)(shi)(shi)客戶(hu)又要(yao)要(yao)求達到(dao)(dao)一(yi)定比例(li)的(de)(de)殘氧量，這(zhe)就(jiu)很矛盾(dun)了。
