真(zhen)空包裝(zhuang)機(ji)廠的(de)(de)真空包(bao)裝機增加充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)功能是(shi)(shi)(shi)有兩種方(fang)(fang)式，一種是(shi)(shi)(shi)氣(qi)(qi)(qi)嘴(zui)直接伸到(dao)產(chan)品(pin)(pin)(pin)袋子里(li)(li)面進(jin)行充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)(de)，另一種是(shi)(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)(chong)的(de)(de)氣(qi)(qi)(qi)體先充(chong)(chong)(chong)(chong)滿(man)整(zheng)個真空室，然后靠負壓差充(chong)(chong)(chong)(chong)滿(man)袋子。那究(jiu)竟采用(yong)(yong)哪種方(fang)(fang)式充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)好(hao)(hao)呢，這(zhe)里(li)(li)主要(yao)(yao)看(kan)客(ke)(ke)戶(hu)的(de)(de)產(chan)品(pin)(pin)(pin)性質，單純(chun)來說(shuo)肯定(ding)是(shi)(shi)(shi)直接沖到(dao)袋子里(li)(li)比較好(hao)(hao)，這(zhe)樣置換的(de)(de)又(you)純(chun)還能省不少氣(qi)(qi)(qi)源，但是(shi)(shi)(shi)大家(jia)一定(ding)要(yao)(yao)考(kao)慮(lv)好(hao)(hao)自己產(chan)品(pin)(pin)(pin)性質。如(ru)果產(chan)品(pin)(pin)(pin)是(shi)(shi)(shi)顆粒，我們(men)可以采取起初(chu)一種方(fang)(fang)法直接讓充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)嘴(zui)到(dao)袋子里(li)(li)進(jin)行充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)，但是(shi)(shi)(shi)如(ru)果你的(de)(de)產(chan)品(pin)(pin)(pin)是(shi)(shi)(shi)粉末狀的(de)(de)就不能用(yong)(yong)起初(chu)一種方(fang)(fang)法了(le)，需要(yao)(yao)第二種在真空室充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)利用(yong)(yong)壓力差充(chong)(chong)(chong)(chong)滿(man)袋子。可是(shi)(shi)(shi)客(ke)(ke)戶(hu)又(you)要(yao)(yao)要(yao)(yao)求達到(dao)一定(ding)比例的(de)(de)殘氧量(liang)，這(zhe)就很(hen)矛(mao)盾了(le)。
