真(zhen)空(kong)包裝(zhuang)機(ji)廠的(de)真(zhen)空(kong)(kong)包裝機(ji)增加充(chong)(chong)(chong)(chong)(chong)氣功能是(shi)有(you)兩種(zhong)(zhong)方式，一(yi)(yi)種(zhong)(zhong)是(shi)氣嘴(zui)(zui)直接伸到(dao)產品(pin)袋子(zi)(zi)里(li)面(mian)進行充(chong)(chong)(chong)(chong)(chong)氣的(de)，另一(yi)(yi)種(zhong)(zhong)是(shi)把要(yao)(yao)充(chong)(chong)(chong)(chong)(chong)的(de)氣體先充(chong)(chong)(chong)(chong)(chong)滿整個真(zhen)空(kong)(kong)室，然后靠(kao)負壓(ya)差充(chong)(chong)(chong)(chong)(chong)滿袋子(zi)(zi)。那究竟(jing)采用哪種(zhong)(zhong)方式充(chong)(chong)(chong)(chong)(chong)氣好呢，這里(li)主要(yao)(yao)看客戶的(de)產品(pin)性質，單(dan)純(chun)來說肯定(ding)是(shi)直接沖到(dao)袋子(zi)(zi)里(li)比較(jiao)好，這樣置換的(de)又純(chun)還能省不少氣源，但(dan)是(shi)大家一(yi)(yi)定(ding)要(yao)(yao)考慮好自己(ji)產品(pin)性質。如果產品(pin)是(shi)顆粒，我們可(ke)以采取起初一(yi)(yi)種(zhong)(zhong)方法直接讓充(chong)(chong)(chong)(chong)(chong)氣嘴(zui)(zui)到(dao)袋子(zi)(zi)里(li)進行充(chong)(chong)(chong)(chong)(chong)氣，但(dan)是(shi)如果你的(de)產品(pin)是(shi)粉(fen)末狀的(de)就不能用起初一(yi)(yi)種(zhong)(zhong)方法了(le)，需要(yao)(yao)第二種(zhong)(zhong)在真(zhen)空(kong)(kong)室充(chong)(chong)(chong)(chong)(chong)氣利(li)用壓(ya)力差充(chong)(chong)(chong)(chong)(chong)滿袋子(zi)(zi)。可(ke)是(shi)客戶又要(yao)(yao)要(yao)(yao)求達到(dao)一(yi)(yi)定(ding)比例的(de)殘氧量，這就很矛盾了(le)。
