真空包裝(zhuang)機廠的(de)(de)(de)(de)真(zhen)空(kong)包裝機增加充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)功能(neng)是(shi)(shi)有兩種(zhong)方式(shi)，一(yi)種(zhong)是(shi)(shi)氣(qi)(qi)(qi)嘴直(zhi)接伸到產(chan)品(pin)袋(dai)子(zi)(zi)里(li)面(mian)進(jin)行充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)(de)(de)(de)，另一(yi)種(zhong)是(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)(chong)的(de)(de)(de)(de)氣(qi)(qi)(qi)體先(xian)充(chong)(chong)(chong)(chong)滿整(zheng)個真(zhen)空(kong)室，然后靠負(fu)壓(ya)差充(chong)(chong)(chong)(chong)滿袋(dai)子(zi)(zi)。那究竟采用(yong)(yong)哪種(zhong)方式(shi)充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)好(hao)(hao)呢，這(zhe)里(li)主要(yao)(yao)看客(ke)戶的(de)(de)(de)(de)產(chan)品(pin)性(xing)(xing)質，單純來說肯定(ding)(ding)是(shi)(shi)直(zhi)接沖到袋(dai)子(zi)(zi)里(li)比(bi)較好(hao)(hao)，這(zhe)樣置換的(de)(de)(de)(de)又(you)純還能(neng)省不少(shao)氣(qi)(qi)(qi)源，但(dan)是(shi)(shi)大家一(yi)定(ding)(ding)要(yao)(yao)考慮好(hao)(hao)自(zi)己產(chan)品(pin)性(xing)(xing)質。如果產(chan)品(pin)是(shi)(shi)顆粒，我們可以(yi)采取起初(chu)一(yi)種(zhong)方法直(zhi)接讓充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)嘴到袋(dai)子(zi)(zi)里(li)進(jin)行充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)，但(dan)是(shi)(shi)如果你的(de)(de)(de)(de)產(chan)品(pin)是(shi)(shi)粉末狀的(de)(de)(de)(de)就(jiu)不能(neng)用(yong)(yong)起初(chu)一(yi)種(zhong)方法了(le)，需要(yao)(yao)第二種(zhong)在真(zhen)空(kong)室充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)利用(yong)(yong)壓(ya)力差充(chong)(chong)(chong)(chong)滿袋(dai)子(zi)(zi)。可是(shi)(shi)客(ke)戶又(you)要(yao)(yao)要(yao)(yao)求達(da)到一(yi)定(ding)(ding)比(bi)例的(de)(de)(de)(de)殘氧量，這(zhe)就(jiu)很(hen)矛盾(dun)了(le)。
