真(zhen)空(kong)包裝機廠的(de)真空包裝機增加充(chong)(chong)(chong)氣(qi)功能是(shi)(shi)有兩種(zhong)方(fang)式，一(yi)(yi)種(zhong)是(shi)(shi)氣(qi)嘴(zui)直接伸到(dao)產(chan)品(pin)袋子(zi)(zi)里(li)面進行(xing)充(chong)(chong)(chong)氣(qi)的(de)，另一(yi)(yi)種(zhong)是(shi)(shi)把要充(chong)(chong)(chong)的(de)氣(qi)體先(xian)充(chong)(chong)(chong)滿整個真空室，然后靠(kao)負(fu)壓差充(chong)(chong)(chong)滿袋子(zi)(zi)。那究竟采(cai)用哪種(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)好(hao)(hao)呢，這(zhe)里(li)主要看(kan)客(ke)戶的(de)產(chan)品(pin)性(xing)質，單純(chun)來說肯定(ding)是(shi)(shi)直接沖到(dao)袋子(zi)(zi)里(li)比較好(hao)(hao)，這(zhe)樣(yang)置換的(de)又(you)純(chun)還能省(sheng)不少氣(qi)源(yuan)，但是(shi)(shi)大家(jia)一(yi)(yi)定(ding)要考慮好(hao)(hao)自己(ji)產(chan)品(pin)性(xing)質。如果產(chan)品(pin)是(shi)(shi)顆粒，我們可以采(cai)取(qu)起(qi)初一(yi)(yi)種(zhong)方(fang)法直接讓充(chong)(chong)(chong)氣(qi)嘴(zui)到(dao)袋子(zi)(zi)里(li)進行(xing)充(chong)(chong)(chong)氣(qi)，但是(shi)(shi)如果你的(de)產(chan)品(pin)是(shi)(shi)粉末狀的(de)就不能用起(qi)初一(yi)(yi)種(zhong)方(fang)法了(le)，需要第二種(zhong)在(zai)真空室充(chong)(chong)(chong)氣(qi)利用壓力差充(chong)(chong)(chong)滿袋子(zi)(zi)。可是(shi)(shi)客(ke)戶又(you)要要求達到(dao)一(yi)(yi)定(ding)比例(li)的(de)殘氧量，這(zhe)就很(hen)矛盾了(le)。
