真空包裝機廠(chang)的(de)真(zhen)(zhen)空(kong)包(bao)裝機增(zeng)加充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)有兩種(zhong)方式，一(yi)種(zhong)是(shi)氣(qi)(qi)嘴直(zhi)接伸到產(chan)(chan)品(pin)袋(dai)子里(li)(li)面進行(xing)充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)的(de)，另(ling)一(yi)種(zhong)是(shi)把要充(chong)(chong)(chong)(chong)(chong)的(de)氣(qi)(qi)體先充(chong)(chong)(chong)(chong)(chong)滿(man)整個真(zhen)(zhen)空(kong)室，然后靠負(fu)壓差充(chong)(chong)(chong)(chong)(chong)滿(man)袋(dai)子。那究竟采用(yong)(yong)哪種(zhong)方式充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)好(hao)呢，這(zhe)里(li)(li)主要看客(ke)戶的(de)產(chan)(chan)品(pin)性(xing)質，單(dan)純(chun)來說肯定(ding)是(shi)直(zhi)接沖到袋(dai)子里(li)(li)比較好(hao)，這(zhe)樣置換的(de)又純(chun)還能(neng)省不少氣(qi)(qi)源，但(dan)是(shi)大家一(yi)定(ding)要考慮好(hao)自己產(chan)(chan)品(pin)性(xing)質。如(ru)(ru)果產(chan)(chan)品(pin)是(shi)顆(ke)粒，我(wo)們可(ke)以采取起初(chu)一(yi)種(zhong)方法直(zhi)接讓充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)嘴到袋(dai)子里(li)(li)進行(xing)充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)，但(dan)是(shi)如(ru)(ru)果你(ni)的(de)產(chan)(chan)品(pin)是(shi)粉末狀的(de)就不能(neng)用(yong)(yong)起初(chu)一(yi)種(zhong)方法了(le)，需要第二種(zhong)在真(zhen)(zhen)空(kong)室充(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)利用(yong)(yong)壓力(li)差充(chong)(chong)(chong)(chong)(chong)滿(man)袋(dai)子。可(ke)是(shi)客(ke)戶又要要求達到一(yi)定(ding)比例(li)的(de)殘氧量，這(zhe)就很矛盾(dun)了(le)。
