真空包裝機(ji)廠的(de)(de)真(zhen)空包裝機(ji)增加充(chong)(chong)(chong)氣(qi)(qi)(qi)功能是(shi)(shi)有兩種方式，一(yi)(yi)種是(shi)(shi)氣(qi)(qi)(qi)嘴直接伸到(dao)產(chan)品(pin)袋(dai)子里(li)面進行充(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)(de)，另一(yi)(yi)種是(shi)(shi)把要充(chong)(chong)(chong)的(de)(de)氣(qi)(qi)(qi)體先充(chong)(chong)(chong)滿整個真(zhen)空室，然后靠負壓(ya)差(cha)充(chong)(chong)(chong)滿袋(dai)子。那究竟采用哪種方式充(chong)(chong)(chong)氣(qi)(qi)(qi)好(hao)呢，這(zhe)里(li)主要看客戶的(de)(de)產(chan)品(pin)性(xing)質，單純(chun)來說(shuo)肯定(ding)是(shi)(shi)直接沖到(dao)袋(dai)子里(li)比(bi)較好(hao)，這(zhe)樣置換的(de)(de)又純(chun)還能省不少氣(qi)(qi)(qi)源，但(dan)(dan)是(shi)(shi)大家一(yi)(yi)定(ding)要考慮(lv)好(hao)自己產(chan)品(pin)性(xing)質。如(ru)果產(chan)品(pin)是(shi)(shi)顆粒，我們可(ke)以采取起初(chu)一(yi)(yi)種方法直接讓充(chong)(chong)(chong)氣(qi)(qi)(qi)嘴到(dao)袋(dai)子里(li)進行充(chong)(chong)(chong)氣(qi)(qi)(qi)，但(dan)(dan)是(shi)(shi)如(ru)果你的(de)(de)產(chan)品(pin)是(shi)(shi)粉(fen)末狀(zhuang)的(de)(de)就不能用起初(chu)一(yi)(yi)種方法了，需要第二種在真(zhen)空室充(chong)(chong)(chong)氣(qi)(qi)(qi)利(li)用壓(ya)力(li)差(cha)充(chong)(chong)(chong)滿袋(dai)子。可(ke)是(shi)(shi)客戶又要要求達到(dao)一(yi)(yi)定(ding)比(bi)例的(de)(de)殘氧(yang)量(liang)，這(zhe)就很矛盾了。
