真空包裝機廠的(de)真空(kong)包裝機增加(jia)充(chong)(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)有兩種(zhong)方(fang)(fang)式，一(yi)種(zhong)是(shi)氣(qi)(qi)嘴直接伸到(dao)(dao)產(chan)(chan)(chan)品(pin)袋(dai)子里(li)面進行(xing)充(chong)(chong)(chong)(chong)氣(qi)(qi)的(de)，另一(yi)種(zhong)是(shi)把要(yao)充(chong)(chong)(chong)(chong)的(de)氣(qi)(qi)體先充(chong)(chong)(chong)(chong)滿(man)(man)(man)整個(ge)真空(kong)室(shi)，然后靠負壓差(cha)充(chong)(chong)(chong)(chong)滿(man)(man)(man)袋(dai)子。那究竟采用哪種(zhong)方(fang)(fang)式充(chong)(chong)(chong)(chong)氣(qi)(qi)好呢，這里(li)主要(yao)看客(ke)戶的(de)產(chan)(chan)(chan)品(pin)性質(zhi)，單純(chun)來說(shuo)肯定是(shi)直接沖到(dao)(dao)袋(dai)子里(li)比較好，這樣置換(huan)的(de)又純(chun)還能(neng)省不少氣(qi)(qi)源(yuan)，但(dan)是(shi)大家一(yi)定要(yao)考慮好自(zi)己產(chan)(chan)(chan)品(pin)性質(zhi)。如果產(chan)(chan)(chan)品(pin)是(shi)顆(ke)粒，我們可(ke)以采取起(qi)初(chu)(chu)一(yi)種(zhong)方(fang)(fang)法直接讓充(chong)(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)(dao)袋(dai)子里(li)進行(xing)充(chong)(chong)(chong)(chong)氣(qi)(qi)，但(dan)是(shi)如果你的(de)產(chan)(chan)(chan)品(pin)是(shi)粉(fen)末狀的(de)就(jiu)不能(neng)用起(qi)初(chu)(chu)一(yi)種(zhong)方(fang)(fang)法了，需要(yao)第(di)二種(zhong)在真空(kong)室(shi)充(chong)(chong)(chong)(chong)氣(qi)(qi)利用壓力(li)差(cha)充(chong)(chong)(chong)(chong)滿(man)(man)(man)袋(dai)子。可(ke)是(shi)客(ke)戶又要(yao)要(yao)求達到(dao)(dao)一(yi)定比例的(de)殘(can)氧量，這就(jiu)很矛盾了。
