真(zhen)空包裝機廠(chang)的(de)真空(kong)包裝機增加充(chong)(chong)(chong)(chong)氣功能(neng)是(shi)(shi)有兩種方(fang)(fang)式，一(yi)(yi)種是(shi)(shi)氣嘴直(zhi)接伸到(dao)產(chan)品(pin)袋(dai)子里(li)面進行充(chong)(chong)(chong)(chong)氣的(de)，另一(yi)(yi)種是(shi)(shi)把(ba)要(yao)(yao)充(chong)(chong)(chong)(chong)的(de)氣體先充(chong)(chong)(chong)(chong)滿(man)整個真空(kong)室，然(ran)后靠負壓差(cha)充(chong)(chong)(chong)(chong)滿(man)袋(dai)子。那究竟采(cai)用(yong)哪種方(fang)(fang)式充(chong)(chong)(chong)(chong)氣好呢，這(zhe)里(li)主要(yao)(yao)看客(ke)(ke)戶的(de)產(chan)品(pin)性質，單純(chun)來說肯(ken)定(ding)是(shi)(shi)直(zhi)接沖到(dao)袋(dai)子里(li)比較好，這(zhe)樣置換的(de)又純(chun)還能(neng)省不(bu)少氣源，但(dan)是(shi)(shi)大家(jia)一(yi)(yi)定(ding)要(yao)(yao)考慮好自己產(chan)品(pin)性質。如果(guo)產(chan)品(pin)是(shi)(shi)顆粒(li)，我(wo)們可(ke)以采(cai)取起初一(yi)(yi)種方(fang)(fang)法(fa)直(zhi)接讓充(chong)(chong)(chong)(chong)氣嘴到(dao)袋(dai)子里(li)進行充(chong)(chong)(chong)(chong)氣，但(dan)是(shi)(shi)如果(guo)你的(de)產(chan)品(pin)是(shi)(shi)粉(fen)末狀的(de)就(jiu)不(bu)能(neng)用(yong)起初一(yi)(yi)種方(fang)(fang)法(fa)了，需要(yao)(yao)第二(er)種在真空(kong)室充(chong)(chong)(chong)(chong)氣利(li)用(yong)壓力差(cha)充(chong)(chong)(chong)(chong)滿(man)袋(dai)子。可(ke)是(shi)(shi)客(ke)(ke)戶又要(yao)(yao)要(yao)(yao)求達(da)到(dao)一(yi)(yi)定(ding)比例的(de)殘氧量，這(zhe)就(jiu)很矛盾(dun)了。
