真空包裝機廠的真空包(bao)裝機增加充(chong)(chong)(chong)氣(qi)(qi)功能是(shi)有兩種(zhong)方(fang)式，一種(zhong)是(shi)氣(qi)(qi)嘴直(zhi)接伸(shen)到(dao)產(chan)(chan)品袋子(zi)里(li)(li)面進行充(chong)(chong)(chong)氣(qi)(qi)的，另(ling)一種(zhong)是(shi)把要充(chong)(chong)(chong)的氣(qi)(qi)體先充(chong)(chong)(chong)滿(man)整個(ge)真空室，然后靠負壓差充(chong)(chong)(chong)滿(man)袋子(zi)。那究竟采用(yong)(yong)哪種(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)(qi)好呢，這里(li)(li)主(zhu)要看客戶的產(chan)(chan)品性(xing)質，單純來說肯(ken)定是(shi)直(zhi)接沖到(dao)袋子(zi)里(li)(li)比較好，這樣置(zhi)換(huan)的又純還能省不(bu)(bu)少氣(qi)(qi)源，但是(shi)大家一定要考慮好自己產(chan)(chan)品性(xing)質。如(ru)果產(chan)(chan)品是(shi)顆粒(li)，我們可(ke)以采取起初一種(zhong)方(fang)法直(zhi)接讓充(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)袋子(zi)里(li)(li)進行充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)如(ru)果你的產(chan)(chan)品是(shi)粉(fen)末狀的就不(bu)(bu)能用(yong)(yong)起初一種(zhong)方(fang)法了，需(xu)要第二種(zhong)在真空室充(chong)(chong)(chong)氣(qi)(qi)利用(yong)(yong)壓力(li)差充(chong)(chong)(chong)滿(man)袋子(zi)。可(ke)是(shi)客戶又要要求達到(dao)一定比例的殘氧(yang)量，這就很矛盾了。
