真空包裝機廠的(de)真空包(bao)裝機增加充(chong)(chong)氣(qi)(qi)功能(neng)是(shi)(shi)有(you)兩種(zhong)方(fang)式，一(yi)種(zhong)是(shi)(shi)氣(qi)(qi)嘴直(zhi)接(jie)伸到產(chan)(chan)品(pin)袋(dai)子(zi)里(li)面進行充(chong)(chong)氣(qi)(qi)的(de)，另一(yi)種(zhong)是(shi)(shi)把(ba)要充(chong)(chong)的(de)氣(qi)(qi)體先充(chong)(chong)滿整(zheng)個(ge)真空室(shi)(shi)，然后靠負(fu)壓(ya)差(cha)充(chong)(chong)滿袋(dai)子(zi)。那究竟采用(yong)哪種(zhong)方(fang)式充(chong)(chong)氣(qi)(qi)好呢，這(zhe)里(li)主要看客戶(hu)的(de)產(chan)(chan)品(pin)性質(zhi)，單純來說肯定是(shi)(shi)直(zhi)接(jie)沖到袋(dai)子(zi)里(li)比(bi)較(jiao)好，這(zhe)樣置換的(de)又純還能(neng)省不少(shao)氣(qi)(qi)源，但是(shi)(shi)大家一(yi)定要考慮好自(zi)己(ji)產(chan)(chan)品(pin)性質(zhi)。如果產(chan)(chan)品(pin)是(shi)(shi)顆粒，我們可(ke)(ke)以(yi)采取起(qi)初一(yi)種(zhong)方(fang)法直(zhi)接(jie)讓充(chong)(chong)氣(qi)(qi)嘴到袋(dai)子(zi)里(li)進行充(chong)(chong)氣(qi)(qi)，但是(shi)(shi)如果你的(de)產(chan)(chan)品(pin)是(shi)(shi)粉末狀的(de)就(jiu)(jiu)不能(neng)用(yong)起(qi)初一(yi)種(zhong)方(fang)法了(le)，需要第二種(zhong)在真空室(shi)(shi)充(chong)(chong)氣(qi)(qi)利用(yong)壓(ya)力差(cha)充(chong)(chong)滿袋(dai)子(zi)。可(ke)(ke)是(shi)(shi)客戶(hu)又要要求達到一(yi)定比(bi)例的(de)殘(can)氧(yang)量，這(zhe)就(jiu)(jiu)很矛盾(dun)了(le)。
