真空包裝機廠的(de)真(zhen)空(kong)包裝機增(zeng)加充(chong)(chong)氣(qi)(qi)(qi)(qi)功能(neng)是(shi)(shi)有(you)兩種(zhong)方(fang)式(shi)，一(yi)種(zhong)是(shi)(shi)氣(qi)(qi)(qi)(qi)嘴(zui)直(zhi)(zhi)接(jie)伸到(dao)產(chan)品(pin)(pin)袋(dai)(dai)子(zi)里面進行充(chong)(chong)氣(qi)(qi)(qi)(qi)的(de)，另一(yi)種(zhong)是(shi)(shi)把要(yao)充(chong)(chong)的(de)氣(qi)(qi)(qi)(qi)體(ti)先充(chong)(chong)滿整個真(zhen)空(kong)室，然后靠負壓差(cha)充(chong)(chong)滿袋(dai)(dai)子(zi)。那(nei)究竟(jing)采用(yong)(yong)哪種(zhong)方(fang)式(shi)充(chong)(chong)氣(qi)(qi)(qi)(qi)好(hao)呢，這里主要(yao)看客戶的(de)產(chan)品(pin)(pin)性(xing)質，單純(chun)來說肯定是(shi)(shi)直(zhi)(zhi)接(jie)沖到(dao)袋(dai)(dai)子(zi)里比較好(hao)，這樣置換(huan)的(de)又純(chun)還(huan)能(neng)省不少氣(qi)(qi)(qi)(qi)源(yuan)，但是(shi)(shi)大家一(yi)定要(yao)考慮好(hao)自己產(chan)品(pin)(pin)性(xing)質。如果(guo)產(chan)品(pin)(pin)是(shi)(shi)顆粒，我(wo)們可以采取起(qi)(qi)初一(yi)種(zhong)方(fang)法直(zhi)(zhi)接(jie)讓充(chong)(chong)氣(qi)(qi)(qi)(qi)嘴(zui)到(dao)袋(dai)(dai)子(zi)里進行充(chong)(chong)氣(qi)(qi)(qi)(qi)，但是(shi)(shi)如果(guo)你的(de)產(chan)品(pin)(pin)是(shi)(shi)粉末狀的(de)就(jiu)不能(neng)用(yong)(yong)起(qi)(qi)初一(yi)種(zhong)方(fang)法了，需要(yao)第二種(zhong)在真(zhen)空(kong)室充(chong)(chong)氣(qi)(qi)(qi)(qi)利用(yong)(yong)壓力差(cha)充(chong)(chong)滿袋(dai)(dai)子(zi)。可是(shi)(shi)客戶又要(yao)要(yao)求達到(dao)一(yi)定比例的(de)殘氧量，這就(jiu)很矛盾了。
