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(neng)是(shi)(shi)有兩種(zhong)方(fang)(fang)式(shi)，一(yi)種(zhong)是(shi)(shi)氣(qi)嘴(zui)直接伸到(dao)(dao)(dao)產(chan)品袋子(zi)里面進行(xing)充(chong)(chong)(chong)氣(qi)的(de)，另一(yi)種(zhong)是(shi)(shi)把(ba)要(yao)充(chong)(chong)(chong)的(de)氣(qi)體先充(chong)(chong)(chong)滿整(zheng)個真空室，然后(hou)靠(kao)負壓(ya)(ya)差充(chong)(chong)(chong)滿袋子(zi)。那究竟(jing)采用哪種(zhong)方(fang)(fang)式(shi)充(chong)(chong)(chong)氣(qi)好呢，這(zhe)里主要(yao)看(kan)客戶的(de)產(chan)品性質，單純來說肯定是(shi)(shi)直接沖到(dao)(dao)(dao)袋子(zi)里比(bi)較好，這(zhe)樣置(zhi)換的(de)又純還能(neng)省(sheng)不少氣(qi)源，但是(shi)(shi)大家一(yi)定要(yao)考慮好自(zi)己(ji)產(chan)品性質。如果(guo)產(chan)品是(shi)(shi)顆粒，我們可(ke)以采取起初(chu)一(yi)種(zhong)方(fang)(fang)法直接讓充(chong)(chong)(chong)氣(qi)嘴(zui)到(dao)(dao)(dao)袋子(zi)里進行(xing)充(chong)(chong)(chong)氣(qi)，但是(shi)(shi)如果(guo)你(ni)的(de)產(chan)品是(shi)(shi)粉(fen)末(mo)狀的(de)就不能(neng)用起初(chu)一(yi)種(zhong)方(fang)(fang)法了(le)，需要(yao)第(di)二種(zhong)在真空室充(chong)(chong)(chong)氣(qi)利用壓(ya)(ya)力差充(chong)(chong)(chong)滿袋子(zi)。可(ke)是(shi)(shi)客戶又要(yao)要(yao)求達到(dao)(dao)(dao)一(yi)定比(bi)例的(de)殘氧量，這(zhe)就很(hen)矛(mao)盾了(le)。
