真空包裝(zhuang)機廠的(de)(de)真空包裝(zhuang)機增加充(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)(shi)有兩(liang)種(zhong)方式，一(yi)種(zhong)是(shi)(shi)氣(qi)(qi)嘴直接伸(shen)到產(chan)品袋子(zi)里面進行充(chong)(chong)(chong)氣(qi)(qi)的(de)(de)，另一(yi)種(zhong)是(shi)(shi)把要(yao)充(chong)(chong)(chong)的(de)(de)氣(qi)(qi)體先充(chong)(chong)(chong)滿整個真空室，然后靠負壓差(cha)充(chong)(chong)(chong)滿袋子(zi)。那究竟(jing)采用(yong)哪種(zhong)方式充(chong)(chong)(chong)氣(qi)(qi)好(hao)呢(ni)，這里主要(yao)看客戶(hu)的(de)(de)產(chan)品性質，單純來說肯定是(shi)(shi)直接沖到袋子(zi)里比較好(hao)，這樣置換的(de)(de)又(you)純還(huan)能(neng)省(sheng)不(bu)少氣(qi)(qi)源，但是(shi)(shi)大家一(yi)定要(yao)考慮(lv)好(hao)自己產(chan)品性質。如果產(chan)品是(shi)(shi)顆粒，我們可(ke)以采取起初(chu)一(yi)種(zhong)方法(fa)直接讓充(chong)(chong)(chong)氣(qi)(qi)嘴到袋子(zi)里進行充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)(shi)如果你(ni)的(de)(de)產(chan)品是(shi)(shi)粉末狀的(de)(de)就不(bu)能(neng)用(yong)起初(chu)一(yi)種(zhong)方法(fa)了(le)，需要(yao)第二種(zhong)在真空室充(chong)(chong)(chong)氣(qi)(qi)利(li)用(yong)壓力差(cha)充(chong)(chong)(chong)滿袋子(zi)。可(ke)是(shi)(shi)客戶(hu)又(you)要(yao)要(yao)求達到一(yi)定比例的(de)(de)殘氧(yang)量(liang)，這就很矛盾了(le)。
