真(zhen)空包裝(zhuang)機廠的真(zhen)空包裝機(ji)增加充(chong)(chong)氣(qi)(qi)功能(neng)是(shi)有兩種(zhong)(zhong)(zhong)方式(shi)，一種(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)嘴直接伸到產(chan)品袋子(zi)里(li)面進(jin)行(xing)充(chong)(chong)氣(qi)(qi)的，另一種(zhong)(zhong)(zhong)是(shi)把要(yao)充(chong)(chong)的氣(qi)(qi)體先充(chong)(chong)滿(man)整(zheng)個真(zhen)空室，然(ran)后(hou)靠負壓(ya)差充(chong)(chong)滿(man)袋子(zi)。那(nei)究竟采用哪種(zhong)(zhong)(zhong)方式(shi)充(chong)(chong)氣(qi)(qi)好呢，這(zhe)里(li)主要(yao)看(kan)客戶的產(chan)品性質，單純來說肯定是(shi)直接沖到袋子(zi)里(li)比較(jiao)好，這(zhe)樣置換(huan)的又純還能(neng)省(sheng)不少氣(qi)(qi)源(yuan)，但是(shi)大家一定要(yao)考慮好自己產(chan)品性質。如果產(chan)品是(shi)顆粒(li)，我們(men)可以采取起(qi)初一種(zhong)(zhong)(zhong)方法直接讓(rang)充(chong)(chong)氣(qi)(qi)嘴到袋子(zi)里(li)進(jin)行(xing)充(chong)(chong)氣(qi)(qi)，但是(shi)如果你的產(chan)品是(shi)粉末狀的就不能(neng)用起(qi)初一種(zhong)(zhong)(zhong)方法了，需要(yao)第二種(zhong)(zhong)(zhong)在真(zhen)空室充(chong)(chong)氣(qi)(qi)利用壓(ya)力差充(chong)(chong)滿(man)袋子(zi)。可是(shi)客戶又要(yao)要(yao)求達到一定比例的殘氧量，這(zhe)就很矛盾了。
