真空包裝機廠的(de)真(zhen)空(kong)包裝機增加充(chong)(chong)氣(qi)(qi)功能(neng)是(shi)有兩種(zhong)方式，一(yi)種(zhong)是(shi)氣(qi)(qi)嘴直接伸到(dao)產(chan)品(pin)袋子(zi)(zi)里面進行充(chong)(chong)氣(qi)(qi)的(de)，另(ling)一(yi)種(zhong)是(shi)把要(yao)(yao)充(chong)(chong)的(de)氣(qi)(qi)體(ti)先充(chong)(chong)滿(man)整個真(zhen)空(kong)室(shi)，然后靠(kao)負壓(ya)差充(chong)(chong)滿(man)袋子(zi)(zi)。那究(jiu)竟采用哪(na)種(zhong)方式充(chong)(chong)氣(qi)(qi)好(hao)呢，這(zhe)里主要(yao)(yao)看客戶的(de)產(chan)品(pin)性質，單純來說肯定(ding)是(shi)直接沖(chong)到(dao)袋子(zi)(zi)里比(bi)較好(hao)，這(zhe)樣置換的(de)又(you)純還能(neng)省不少氣(qi)(qi)源，但是(shi)大家一(yi)定(ding)要(yao)(yao)考慮好(hao)自己產(chan)品(pin)性質。如果產(chan)品(pin)是(shi)顆粒，我們可以采取起初一(yi)種(zhong)方法直接讓充(chong)(chong)氣(qi)(qi)嘴到(dao)袋子(zi)(zi)里進行充(chong)(chong)氣(qi)(qi)，但是(shi)如果你的(de)產(chan)品(pin)是(shi)粉末狀的(de)就不能(neng)用起初一(yi)種(zhong)方法了，需要(yao)(yao)第二種(zhong)在(zai)真(zhen)空(kong)室(shi)充(chong)(chong)氣(qi)(qi)利用壓(ya)力差充(chong)(chong)滿(man)袋子(zi)(zi)。可是(shi)客戶又(you)要(yao)(yao)要(yao)(yao)求達到(dao)一(yi)定(ding)比(bi)例的(de)殘氧量，這(zhe)就很矛(mao)盾了。
