真(zhen)空包裝(zhuang)機(ji)廠的真空包裝機增加充(chong)(chong)(chong)氣(qi)功(gong)能(neng)是(shi)(shi)(shi)有兩種(zhong)(zhong)方(fang)式，一(yi)種(zhong)(zhong)是(shi)(shi)(shi)氣(qi)嘴(zui)直接伸到產(chan)品(pin)袋(dai)子(zi)里(li)(li)面進行(xing)充(chong)(chong)(chong)氣(qi)的，另(ling)一(yi)種(zhong)(zhong)是(shi)(shi)(shi)把要充(chong)(chong)(chong)的氣(qi)體先充(chong)(chong)(chong)滿(man)整個真空室，然后靠負壓差(cha)充(chong)(chong)(chong)滿(man)袋(dai)子(zi)。那究(jiu)竟采用哪種(zhong)(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)好呢，這里(li)(li)主要看客戶(hu)的產(chan)品(pin)性質，單純來說肯定是(shi)(shi)(shi)直接沖到袋(dai)子(zi)里(li)(li)比(bi)較好，這樣置換的又純還(huan)能(neng)省不少氣(qi)源(yuan)，但是(shi)(shi)(shi)大家一(yi)定要考慮好自己(ji)產(chan)品(pin)性質。如果(guo)產(chan)品(pin)是(shi)(shi)(shi)顆粒，我們可(ke)(ke)以采取起初一(yi)種(zhong)(zhong)方(fang)法(fa)直接讓充(chong)(chong)(chong)氣(qi)嘴(zui)到袋(dai)子(zi)里(li)(li)進行(xing)充(chong)(chong)(chong)氣(qi)，但是(shi)(shi)(shi)如果(guo)你的產(chan)品(pin)是(shi)(shi)(shi)粉末狀的就不能(neng)用起初一(yi)種(zhong)(zhong)方(fang)法(fa)了，需要第二(er)種(zhong)(zhong)在真空室充(chong)(chong)(chong)氣(qi)利用壓力差(cha)充(chong)(chong)(chong)滿(man)袋(dai)子(zi)。可(ke)(ke)是(shi)(shi)(shi)客戶(hu)又要要求達(da)到一(yi)定比(bi)例的殘(can)氧量，這就很矛(mao)盾了。
