真空包裝機(ji)廠的(de)(de)真空(kong)包裝機增(zeng)加充(chong)(chong)(chong)氣(qi)功能是(shi)有(you)兩種方(fang)式，一(yi)種是(shi)氣(qi)嘴直接伸到(dao)產品(pin)袋(dai)子(zi)里(li)面進行(xing)(xing)充(chong)(chong)(chong)氣(qi)的(de)(de)，另(ling)一(yi)種是(shi)把要(yao)充(chong)(chong)(chong)的(de)(de)氣(qi)體先充(chong)(chong)(chong)滿(man)(man)整個真空(kong)室(shi)，然(ran)后靠負壓差(cha)充(chong)(chong)(chong)滿(man)(man)袋(dai)子(zi)。那究竟采用哪種方(fang)式充(chong)(chong)(chong)氣(qi)好呢，這里(li)主要(yao)看(kan)客戶的(de)(de)產品(pin)性(xing)質(zhi)，單純(chun)來(lai)說肯定是(shi)直接沖到(dao)袋(dai)子(zi)里(li)比較好，這樣置換的(de)(de)又(you)純(chun)還(huan)能省(sheng)不少氣(qi)源，但(dan)是(shi)大(da)家一(yi)定要(yao)考慮好自(zi)己(ji)產品(pin)性(xing)質(zhi)。如果產品(pin)是(shi)顆粒，我們(men)可(ke)(ke)以采取(qu)起初(chu)一(yi)種方(fang)法直接讓(rang)充(chong)(chong)(chong)氣(qi)嘴到(dao)袋(dai)子(zi)里(li)進行(xing)(xing)充(chong)(chong)(chong)氣(qi)，但(dan)是(shi)如果你(ni)的(de)(de)產品(pin)是(shi)粉末狀的(de)(de)就不能用起初(chu)一(yi)種方(fang)法了，需要(yao)第二種在真空(kong)室(shi)充(chong)(chong)(chong)氣(qi)利用壓力差(cha)充(chong)(chong)(chong)滿(man)(man)袋(dai)子(zi)。可(ke)(ke)是(shi)客戶又(you)要(yao)要(yao)求達(da)到(dao)一(yi)定比例的(de)(de)殘氧量，這就很(hen)矛盾了。
