真空包裝機廠的(de)真空(kong)(kong)(kong)包裝機增(zeng)加充(chong)(chong)氣(qi)(qi)(qi)(qi)功能(neng)是(shi)(shi)有兩種(zhong)(zhong)方(fang)(fang)式，一種(zhong)(zhong)是(shi)(shi)氣(qi)(qi)(qi)(qi)嘴直接伸到(dao)產品(pin)袋(dai)子(zi)里面進行充(chong)(chong)氣(qi)(qi)(qi)(qi)的(de)，另一種(zhong)(zhong)是(shi)(shi)把(ba)要(yao)(yao)(yao)充(chong)(chong)的(de)氣(qi)(qi)(qi)(qi)體先充(chong)(chong)滿整個真空(kong)(kong)(kong)室，然后靠負壓差充(chong)(chong)滿袋(dai)子(zi)。那究竟(jing)采用哪種(zhong)(zhong)方(fang)(fang)式充(chong)(chong)氣(qi)(qi)(qi)(qi)好呢，這里主要(yao)(yao)(yao)看客(ke)(ke)戶的(de)產品(pin)性質，單純來說肯定(ding)(ding)是(shi)(shi)直接沖(chong)到(dao)袋(dai)子(zi)里比較好，這樣置換的(de)又(you)純還能(neng)省不少氣(qi)(qi)(qi)(qi)源，但是(shi)(shi)大(da)家一定(ding)(ding)要(yao)(yao)(yao)考慮(lv)好自己產品(pin)性質。如果產品(pin)是(shi)(shi)顆粒，我們可以采取起初一種(zhong)(zhong)方(fang)(fang)法直接讓充(chong)(chong)氣(qi)(qi)(qi)(qi)嘴到(dao)袋(dai)子(zi)里進行充(chong)(chong)氣(qi)(qi)(qi)(qi)，但是(shi)(shi)如果你的(de)產品(pin)是(shi)(shi)粉末狀的(de)就(jiu)不能(neng)用起初一種(zhong)(zhong)方(fang)(fang)法了(le)(le)，需要(yao)(yao)(yao)第二種(zhong)(zhong)在(zai)真空(kong)(kong)(kong)室充(chong)(chong)氣(qi)(qi)(qi)(qi)利用壓力(li)差充(chong)(chong)滿袋(dai)子(zi)。可是(shi)(shi)客(ke)(ke)戶又(you)要(yao)(yao)(yao)要(yao)(yao)(yao)求達到(dao)一定(ding)(ding)比例(li)的(de)殘氧量，這就(jiu)很矛盾(dun)了(le)(le)。
