真空包(bao)裝機廠(chang)的(de)(de)真空包裝機增加充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)功能是(shi)(shi)(shi)有兩種(zhong)方(fang)式，一(yi)(yi)種(zhong)是(shi)(shi)(shi)氣(qi)(qi)(qi)嘴(zui)直接(jie)伸到(dao)產品(pin)袋子里面進行充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)(de)，另一(yi)(yi)種(zhong)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)整個真空室(shi)，然后靠(kao)負壓差(cha)(cha)充(chong)(chong)(chong)(chong)滿(man)袋子。那究竟采用哪種(zhong)方(fang)式充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)好(hao)呢，這(zhe)里主要(yao)(yao)看客(ke)戶的(de)(de)產品(pin)性(xing)質(zhi)(zhi)，單純(chun)來說肯定(ding)是(shi)(shi)(shi)直接(jie)沖到(dao)袋子里比較(jiao)好(hao)，這(zhe)樣置換的(de)(de)又純(chun)還能省(sheng)不少(shao)氣(qi)(qi)(qi)源，但(dan)是(shi)(shi)(shi)大家一(yi)(yi)定(ding)要(yao)(yao)考慮(lv)好(hao)自(zi)己產品(pin)性(xing)質(zhi)(zhi)。如(ru)(ru)果產品(pin)是(shi)(shi)(shi)顆(ke)粒(li)，我們可以采取起初一(yi)(yi)種(zhong)方(fang)法直接(jie)讓充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)嘴(zui)到(dao)袋子里進行充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)，但(dan)是(shi)(shi)(shi)如(ru)(ru)果你(ni)的(de)(de)產品(pin)是(shi)(shi)(shi)粉(fen)末(mo)狀(zhuang)的(de)(de)就不能用起初一(yi)(yi)種(zhong)方(fang)法了(le)，需要(yao)(yao)第二種(zhong)在真空室(shi)充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)利用壓力差(cha)(cha)充(chong)(chong)(chong)(chong)滿(man)袋子。可是(shi)(shi)(shi)客(ke)戶又要(yao)(yao)要(yao)(yao)求達到(dao)一(yi)(yi)定(ding)比例(li)的(de)(de)殘氧量，這(zhe)就很矛盾了(le)。
