真空(kong)包裝機廠的(de)真空(kong)(kong)(kong)包(bao)裝機增加(jia)充(chong)(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)(shi)有兩種(zhong)(zhong)(zhong)方(fang)(fang)式，一(yi)種(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)(qi)嘴(zui)(zui)直(zhi)接伸(shen)到(dao)產品(pin)(pin)袋子(zi)里(li)面進(jin)(jin)行充(chong)(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)的(de)，另一(yi)種(zhong)(zhong)(zhong)是(shi)(shi)把要充(chong)(chong)(chong)(chong)(chong)(chong)的(de)氣(qi)(qi)體先充(chong)(chong)(chong)(chong)(chong)(chong)滿整(zheng)個真空(kong)(kong)(kong)室，然后靠負(fu)壓差(cha)充(chong)(chong)(chong)(chong)(chong)(chong)滿袋子(zi)。那究竟采用哪種(zhong)(zhong)(zhong)方(fang)(fang)式充(chong)(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)好呢，這(zhe)里(li)主要看客戶(hu)的(de)產品(pin)(pin)性質(zhi)，單純來(lai)說肯定(ding)是(shi)(shi)直(zhi)接沖到(dao)袋子(zi)里(li)比較好，這(zhe)樣置換的(de)又純還能(neng)省不少氣(qi)(qi)源，但(dan)是(shi)(shi)大家一(yi)定(ding)要考(kao)慮好自己產品(pin)(pin)性質(zhi)。如果(guo)(guo)產品(pin)(pin)是(shi)(shi)顆粒(li)，我們可以(yi)采取起(qi)初一(yi)種(zhong)(zhong)(zhong)方(fang)(fang)法直(zhi)接讓充(chong)(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)嘴(zui)(zui)到(dao)袋子(zi)里(li)進(jin)(jin)行充(chong)(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)，但(dan)是(shi)(shi)如果(guo)(guo)你的(de)產品(pin)(pin)是(shi)(shi)粉(fen)末狀的(de)就不能(neng)用起(qi)初一(yi)種(zhong)(zhong)(zhong)方(fang)(fang)法了(le)，需要第二種(zhong)(zhong)(zhong)在真空(kong)(kong)(kong)室充(chong)(chong)(chong)(chong)(chong)(chong)氣(qi)(qi)利(li)用壓力(li)差(cha)充(chong)(chong)(chong)(chong)(chong)(chong)滿袋子(zi)。可是(shi)(shi)客戶(hu)又要要求(qiu)達到(dao)一(yi)定(ding)比例的(de)殘氧量，這(zhe)就很(hen)矛盾了(le)。
