真(zhen)空包裝機廠(chang)的真(zhen)空包(bao)裝(zhuang)機增加充(chong)(chong)氣(qi)(qi)(qi)功能是(shi)(shi)有兩種(zhong)方(fang)(fang)(fang)式，一(yi)種(zhong)是(shi)(shi)氣(qi)(qi)(qi)嘴直接伸到產(chan)(chan)品(pin)(pin)袋(dai)子(zi)里(li)(li)面進行充(chong)(chong)氣(qi)(qi)(qi)的，另一(yi)種(zhong)是(shi)(shi)把要充(chong)(chong)的氣(qi)(qi)(qi)體先充(chong)(chong)滿整個真(zhen)空室，然后靠負壓差(cha)充(chong)(chong)滿袋(dai)子(zi)。那究竟采用哪種(zhong)方(fang)(fang)(fang)式充(chong)(chong)氣(qi)(qi)(qi)好呢，這(zhe)里(li)(li)主要看客(ke)戶的產(chan)(chan)品(pin)(pin)性質(zhi)(zhi)，單純(chun)來說肯定是(shi)(shi)直接沖到袋(dai)子(zi)里(li)(li)比(bi)較好，這(zhe)樣置換的又純(chun)還能省不(bu)少氣(qi)(qi)(qi)源(yuan)，但(dan)(dan)是(shi)(shi)大家(jia)一(yi)定要考慮好自己(ji)產(chan)(chan)品(pin)(pin)性質(zhi)(zhi)。如果(guo)產(chan)(chan)品(pin)(pin)是(shi)(shi)顆粒(li)，我們可(ke)以采取起初一(yi)種(zhong)方(fang)(fang)(fang)法(fa)直接讓(rang)充(chong)(chong)氣(qi)(qi)(qi)嘴到袋(dai)子(zi)里(li)(li)進行充(chong)(chong)氣(qi)(qi)(qi)，但(dan)(dan)是(shi)(shi)如果(guo)你的產(chan)(chan)品(pin)(pin)是(shi)(shi)粉末狀的就不(bu)能用起初一(yi)種(zhong)方(fang)(fang)(fang)法(fa)了，需(xu)要第二種(zhong)在真(zhen)空室充(chong)(chong)氣(qi)(qi)(qi)利用壓力差(cha)充(chong)(chong)滿袋(dai)子(zi)。可(ke)是(shi)(shi)客(ke)戶又要要求達到一(yi)定比(bi)例的殘氧量，這(zhe)就很矛(mao)盾了。
