真空包裝機廠的真(zhen)空(kong)包(bao)裝機增加(jia)充(chong)(chong)(chong)氣(qi)(qi)功能是(shi)有兩種方(fang)(fang)式，一(yi)(yi)(yi)種是(shi)氣(qi)(qi)嘴直(zhi)接伸到(dao)產(chan)品袋(dai)子(zi)里面進(jin)行充(chong)(chong)(chong)氣(qi)(qi)的，另一(yi)(yi)(yi)種是(shi)把要(yao)充(chong)(chong)(chong)的氣(qi)(qi)體先充(chong)(chong)(chong)滿(man)整個真(zhen)空(kong)室(shi)，然后靠(kao)負壓(ya)差充(chong)(chong)(chong)滿(man)袋(dai)子(zi)。那究竟采(cai)用(yong)哪種方(fang)(fang)式充(chong)(chong)(chong)氣(qi)(qi)好呢(ni)，這(zhe)里主要(yao)看客(ke)戶的產(chan)品性質，單純來(lai)說肯定是(shi)直(zhi)接沖到(dao)袋(dai)子(zi)里比較好，這(zhe)樣(yang)置換的又純還(huan)能省不少氣(qi)(qi)源(yuan)，但是(shi)大家一(yi)(yi)(yi)定要(yao)考慮好自己產(chan)品性質。如果產(chan)品是(shi)顆粒(li)，我(wo)們可以(yi)采(cai)取起(qi)初一(yi)(yi)(yi)種方(fang)(fang)法直(zhi)接讓(rang)充(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)袋(dai)子(zi)里進(jin)行充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)如果你的產(chan)品是(shi)粉末狀的就不能用(yong)起(qi)初一(yi)(yi)(yi)種方(fang)(fang)法了，需要(yao)第二(er)種在(zai)真(zhen)空(kong)室(shi)充(chong)(chong)(chong)氣(qi)(qi)利用(yong)壓(ya)力差充(chong)(chong)(chong)滿(man)袋(dai)子(zi)。可是(shi)客(ke)戶又要(yao)要(yao)求(qiu)達到(dao)一(yi)(yi)(yi)定比例的殘氧量，這(zhe)就很矛盾了。
