真空包裝機廠的真空包裝機(ji)增加充(chong)氣(qi)(qi)(qi)功能(neng)是(shi)(shi)有(you)兩種(zhong)(zhong)(zhong)方(fang)式，一(yi)(yi)種(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)(qi)(qi)嘴直(zhi)接(jie)(jie)伸到產(chan)品(pin)(pin)袋(dai)子(zi)里(li)面(mian)進行充(chong)氣(qi)(qi)(qi)的，另一(yi)(yi)種(zhong)(zhong)(zhong)是(shi)(shi)把(ba)要充(chong)的氣(qi)(qi)(qi)體(ti)先充(chong)滿整個(ge)真空室，然后靠負壓差(cha)充(chong)滿袋(dai)子(zi)。那究(jiu)竟采用哪種(zhong)(zhong)(zhong)方(fang)式充(chong)氣(qi)(qi)(qi)好呢，這里(li)主要看客戶的產(chan)品(pin)(pin)性質(zhi)，單純來說肯定(ding)是(shi)(shi)直(zhi)接(jie)(jie)沖(chong)到袋(dai)子(zi)里(li)比(bi)較好，這樣置換的又(you)純還能(neng)省(sheng)不少氣(qi)(qi)(qi)源，但是(shi)(shi)大家一(yi)(yi)定(ding)要考慮(lv)好自己(ji)產(chan)品(pin)(pin)性質(zhi)。如果(guo)產(chan)品(pin)(pin)是(shi)(shi)顆(ke)粒，我們可以采取起初(chu)一(yi)(yi)種(zhong)(zhong)(zhong)方(fang)法直(zhi)接(jie)(jie)讓充(chong)氣(qi)(qi)(qi)嘴到袋(dai)子(zi)里(li)進行充(chong)氣(qi)(qi)(qi)，但是(shi)(shi)如果(guo)你的產(chan)品(pin)(pin)是(shi)(shi)粉末狀(zhuang)的就(jiu)不能(neng)用起初(chu)一(yi)(yi)種(zhong)(zhong)(zhong)方(fang)法了(le)，需(xu)要第二種(zhong)(zhong)(zhong)在真空室充(chong)氣(qi)(qi)(qi)利用壓力(li)差(cha)充(chong)滿袋(dai)子(zi)。可是(shi)(shi)客戶又(you)要要求達到一(yi)(yi)定(ding)比(bi)例的殘氧量，這就(jiu)很(hen)矛盾了(le)。
