真(zhen)空(kong)包裝機廠(chang)的(de)(de)真(zhen)(zhen)空(kong)包(bao)裝機增加充(chong)(chong)(chong)(chong)氣(qi)(qi)功能是(shi)(shi)有兩種(zhong)(zhong)(zhong)方式(shi)，一(yi)種(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)(qi)嘴直(zhi)(zhi)接(jie)伸到(dao)產(chan)品袋子(zi)里(li)面進行充(chong)(chong)(chong)(chong)氣(qi)(qi)的(de)(de)，另(ling)一(yi)種(zhong)(zhong)(zhong)是(shi)(shi)把要(yao)充(chong)(chong)(chong)(chong)的(de)(de)氣(qi)(qi)體(ti)先充(chong)(chong)(chong)(chong)滿(man)整個真(zhen)(zhen)空(kong)室(shi)，然后靠(kao)負壓差充(chong)(chong)(chong)(chong)滿(man)袋子(zi)。那(nei)究(jiu)竟采(cai)用(yong)哪種(zhong)(zhong)(zhong)方式(shi)充(chong)(chong)(chong)(chong)氣(qi)(qi)好呢，這(zhe)里(li)主要(yao)看(kan)客戶的(de)(de)產(chan)品性質(zhi)，單純(chun)(chun)來說(shuo)肯定是(shi)(shi)直(zhi)(zhi)接(jie)沖到(dao)袋子(zi)里(li)比(bi)較好，這(zhe)樣置換的(de)(de)又(you)純(chun)(chun)還能省(sheng)不少氣(qi)(qi)源，但是(shi)(shi)大家一(yi)定要(yao)考(kao)慮(lv)好自(zi)己產(chan)品性質(zhi)。如果產(chan)品是(shi)(shi)顆(ke)粒，我們可(ke)以采(cai)取起初一(yi)種(zhong)(zhong)(zhong)方法直(zhi)(zhi)接(jie)讓(rang)充(chong)(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)袋子(zi)里(li)進行充(chong)(chong)(chong)(chong)氣(qi)(qi)，但是(shi)(shi)如果你的(de)(de)產(chan)品是(shi)(shi)粉末(mo)狀的(de)(de)就不能用(yong)起初一(yi)種(zhong)(zhong)(zhong)方法了(le)，需要(yao)第(di)二種(zhong)(zhong)(zhong)在真(zhen)(zhen)空(kong)室(shi)充(chong)(chong)(chong)(chong)氣(qi)(qi)利(li)用(yong)壓力差充(chong)(chong)(chong)(chong)滿(man)袋子(zi)。可(ke)是(shi)(shi)客戶又(you)要(yao)要(yao)求達到(dao)一(yi)定比(bi)例的(de)(de)殘氧量，這(zhe)就很矛盾了(le)。
