真空(kong)包裝(zhuang)機廠的(de)(de)(de)真空(kong)包(bao)裝機(ji)增加充(chong)(chong)(chong)氣(qi)功能(neng)是(shi)(shi)有兩種(zhong)(zhong)(zhong)方(fang)式，一(yi)種(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)嘴直接伸到(dao)產(chan)(chan)品(pin)(pin)(pin)袋子里面進行(xing)充(chong)(chong)(chong)氣(qi)的(de)(de)(de)，另一(yi)種(zhong)(zhong)(zhong)是(shi)(shi)把要(yao)充(chong)(chong)(chong)的(de)(de)(de)氣(qi)體(ti)先(xian)充(chong)(chong)(chong)滿(man)整個真空(kong)室，然(ran)后(hou)靠負壓差(cha)充(chong)(chong)(chong)滿(man)袋子。那究竟采(cai)(cai)用(yong)(yong)哪(na)種(zhong)(zhong)(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)好(hao)呢，這(zhe)里主(zhu)要(yao)看(kan)客戶的(de)(de)(de)產(chan)(chan)品(pin)(pin)(pin)性(xing)質，單純(chun)來說肯定(ding)是(shi)(shi)直接沖到(dao)袋子里比(bi)較好(hao)，這(zhe)樣置(zhi)換(huan)的(de)(de)(de)又純(chun)還(huan)能(neng)省不少氣(qi)源(yuan)，但是(shi)(shi)大家一(yi)定(ding)要(yao)考慮好(hao)自己產(chan)(chan)品(pin)(pin)(pin)性(xing)質。如(ru)果產(chan)(chan)品(pin)(pin)(pin)是(shi)(shi)顆(ke)粒，我們可以采(cai)(cai)取起初一(yi)種(zhong)(zhong)(zhong)方(fang)法直接讓充(chong)(chong)(chong)氣(qi)嘴到(dao)袋子里進行(xing)充(chong)(chong)(chong)氣(qi)，但是(shi)(shi)如(ru)果你的(de)(de)(de)產(chan)(chan)品(pin)(pin)(pin)是(shi)(shi)粉末(mo)狀的(de)(de)(de)就不能(neng)用(yong)(yong)起初一(yi)種(zhong)(zhong)(zhong)方(fang)法了，需要(yao)第二種(zhong)(zhong)(zhong)在真空(kong)室充(chong)(chong)(chong)氣(qi)利用(yong)(yong)壓力差(cha)充(chong)(chong)(chong)滿(man)袋子。可是(shi)(shi)客戶又要(yao)要(yao)求達到(dao)一(yi)定(ding)比(bi)例的(de)(de)(de)殘氧量，這(zhe)就很矛(mao)盾了。
