真(zhen)空包裝機廠的(de)(de)(de)真空(kong)包裝機(ji)增加充(chong)(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)(shi)(shi)有兩種方(fang)式，一(yi)(yi)種是(shi)(shi)(shi)氣(qi)(qi)嘴直接(jie)伸到(dao)(dao)產(chan)品(pin)(pin)(pin)袋子(zi)(zi)(zi)里面(mian)進行(xing)充(chong)(chong)(chong)(chong)氣(qi)(qi)的(de)(de)(de)，另一(yi)(yi)種是(shi)(shi)(shi)把要充(chong)(chong)(chong)(chong)的(de)(de)(de)氣(qi)(qi)體(ti)先充(chong)(chong)(chong)(chong)滿整個真空(kong)室(shi)，然后靠負壓差(cha)充(chong)(chong)(chong)(chong)滿袋子(zi)(zi)(zi)。那究竟采用(yong)哪種方(fang)式充(chong)(chong)(chong)(chong)氣(qi)(qi)好呢，這(zhe)里主要看客戶的(de)(de)(de)產(chan)品(pin)(pin)(pin)性(xing)質，單純來說肯定(ding)是(shi)(shi)(shi)直接(jie)沖到(dao)(dao)袋子(zi)(zi)(zi)里比(bi)較好，這(zhe)樣置換的(de)(de)(de)又純還(huan)能(neng)省不少(shao)氣(qi)(qi)源，但是(shi)(shi)(shi)大家一(yi)(yi)定(ding)要考慮好自(zi)己(ji)產(chan)品(pin)(pin)(pin)性(xing)質。如果產(chan)品(pin)(pin)(pin)是(shi)(shi)(shi)顆粒，我們(men)可(ke)以采取(qu)起初(chu)一(yi)(yi)種方(fang)法(fa)直接(jie)讓充(chong)(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)(dao)袋子(zi)(zi)(zi)里進行(xing)充(chong)(chong)(chong)(chong)氣(qi)(qi)，但是(shi)(shi)(shi)如果你的(de)(de)(de)產(chan)品(pin)(pin)(pin)是(shi)(shi)(shi)粉(fen)末狀的(de)(de)(de)就不能(neng)用(yong)起初(chu)一(yi)(yi)種方(fang)法(fa)了(le)，需(xu)要第二種在真空(kong)室(shi)充(chong)(chong)(chong)(chong)氣(qi)(qi)利用(yong)壓力(li)差(cha)充(chong)(chong)(chong)(chong)滿袋子(zi)(zi)(zi)。可(ke)是(shi)(shi)(shi)客戶又要要求達到(dao)(dao)一(yi)(yi)定(ding)比(bi)例的(de)(de)(de)殘氧量，這(zhe)就很矛盾了(le)。
