真(zhen)空(kong)包裝機廠的真空(kong)包裝機增加充(chong)氣(qi)(qi)功(gong)能(neng)是(shi)有兩(liang)種(zhong)(zhong)方(fang)式(shi)，一(yi)種(zhong)(zhong)是(shi)氣(qi)(qi)嘴(zui)直(zhi)接(jie)伸到產(chan)(chan)品(pin)袋(dai)子(zi)里(li)(li)面進(jin)行(xing)充(chong)氣(qi)(qi)的，另(ling)一(yi)種(zhong)(zhong)是(shi)把(ba)要(yao)充(chong)的氣(qi)(qi)體先充(chong)滿整(zheng)個真空(kong)室(shi)(shi)，然(ran)后靠(kao)負壓差(cha)充(chong)滿袋(dai)子(zi)。那究竟采(cai)用(yong)哪種(zhong)(zhong)方(fang)式(shi)充(chong)氣(qi)(qi)好(hao)呢，這里(li)(li)主要(yao)看(kan)客戶(hu)的產(chan)(chan)品(pin)性(xing)質，單(dan)純來說肯定是(shi)直(zhi)接(jie)沖(chong)到袋(dai)子(zi)里(li)(li)比較好(hao)，這樣置換的又(you)純還能(neng)省不(bu)少氣(qi)(qi)源，但是(shi)大家(jia)一(yi)定要(yao)考慮好(hao)自己產(chan)(chan)品(pin)性(xing)質。如果產(chan)(chan)品(pin)是(shi)顆粒，我們可(ke)以采(cai)取起初(chu)一(yi)種(zhong)(zhong)方(fang)法直(zhi)接(jie)讓充(chong)氣(qi)(qi)嘴(zui)到袋(dai)子(zi)里(li)(li)進(jin)行(xing)充(chong)氣(qi)(qi)，但是(shi)如果你的產(chan)(chan)品(pin)是(shi)粉末狀的就(jiu)不(bu)能(neng)用(yong)起初(chu)一(yi)種(zhong)(zhong)方(fang)法了(le)，需要(yao)第二(er)種(zhong)(zhong)在真空(kong)室(shi)(shi)充(chong)氣(qi)(qi)利用(yong)壓力差(cha)充(chong)滿袋(dai)子(zi)。可(ke)是(shi)客戶(hu)又(you)要(yao)要(yao)求(qiu)達(da)到一(yi)定比例的殘氧量，這就(jiu)很(hen)矛(mao)盾了(le)。
