真(zhen)空包(bao)裝機廠的(de)真(zhen)空(kong)(kong)包裝機增加(jia)充(chong)(chong)氣(qi)功(gong)能(neng)是(shi)(shi)(shi)有兩種(zhong)(zhong)方式，一種(zhong)(zhong)是(shi)(shi)(shi)氣(qi)嘴(zui)直接伸到產品(pin)袋子(zi)(zi)里(li)(li)面進行充(chong)(chong)氣(qi)的(de)，另一種(zhong)(zhong)是(shi)(shi)(shi)把要(yao)(yao)充(chong)(chong)的(de)氣(qi)體先充(chong)(chong)滿(man)整個真(zhen)空(kong)(kong)室(shi)，然后靠負壓差充(chong)(chong)滿(man)袋子(zi)(zi)。那究竟采用(yong)哪種(zhong)(zhong)方式充(chong)(chong)氣(qi)好(hao)呢，這(zhe)(zhe)里(li)(li)主要(yao)(yao)看客戶(hu)的(de)產品(pin)性質，單純來說肯定是(shi)(shi)(shi)直接沖到袋子(zi)(zi)里(li)(li)比較好(hao)，這(zhe)(zhe)樣置換(huan)的(de)又純還(huan)能(neng)省不少氣(qi)源，但(dan)是(shi)(shi)(shi)大家一定要(yao)(yao)考慮(lv)好(hao)自己產品(pin)性質。如(ru)果產品(pin)是(shi)(shi)(shi)顆粒，我們可以(yi)采取起(qi)初一種(zhong)(zhong)方法(fa)直接讓充(chong)(chong)氣(qi)嘴(zui)到袋子(zi)(zi)里(li)(li)進行充(chong)(chong)氣(qi)，但(dan)是(shi)(shi)(shi)如(ru)果你的(de)產品(pin)是(shi)(shi)(shi)粉末狀的(de)就(jiu)不能(neng)用(yong)起(qi)初一種(zhong)(zhong)方法(fa)了(le)，需(xu)要(yao)(yao)第二種(zhong)(zhong)在真(zhen)空(kong)(kong)室(shi)充(chong)(chong)氣(qi)利用(yong)壓力差充(chong)(chong)滿(man)袋子(zi)(zi)。可是(shi)(shi)(shi)客戶(hu)又要(yao)(yao)要(yao)(yao)求(qiu)達到一定比例的(de)殘氧量(liang)，這(zhe)(zhe)就(jiu)很矛盾了(le)。
