真(zhen)空包裝機廠(chang)的(de)真空包裝(zhuang)機增加充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)功能是(shi)(shi)(shi)(shi)有兩種方(fang)(fang)式(shi)，一種是(shi)(shi)(shi)(shi)氣(qi)(qi)(qi)(qi)嘴(zui)直(zhi)接伸到產(chan)(chan)品袋子(zi)(zi)里(li)面進行充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)的(de)，另一種是(shi)(shi)(shi)(shi)把要充(chong)(chong)(chong)的(de)氣(qi)(qi)(qi)(qi)體(ti)先充(chong)(chong)(chong)滿整個(ge)真空室，然后靠(kao)負壓(ya)差充(chong)(chong)(chong)滿袋子(zi)(zi)。那究竟采(cai)用哪種方(fang)(fang)式(shi)充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)好呢，這(zhe)里(li)主(zhu)要看客(ke)戶的(de)產(chan)(chan)品性質，單純來(lai)說(shuo)肯定(ding)是(shi)(shi)(shi)(shi)直(zhi)接沖到袋子(zi)(zi)里(li)比(bi)較(jiao)好，這(zhe)樣置換的(de)又純還(huan)能省不(bu)少氣(qi)(qi)(qi)(qi)源，但是(shi)(shi)(shi)(shi)大家一定(ding)要考慮好自己產(chan)(chan)品性質。如果產(chan)(chan)品是(shi)(shi)(shi)(shi)顆粒，我(wo)們可以采(cai)取起(qi)初(chu)一種方(fang)(fang)法(fa)(fa)直(zhi)接讓充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)嘴(zui)到袋子(zi)(zi)里(li)進行充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)，但是(shi)(shi)(shi)(shi)如果你的(de)產(chan)(chan)品是(shi)(shi)(shi)(shi)粉末狀的(de)就不(bu)能用起(qi)初(chu)一種方(fang)(fang)法(fa)(fa)了，需要第二種在真空室充(chong)(chong)(chong)氣(qi)(qi)(qi)(qi)利用壓(ya)力差充(chong)(chong)(chong)滿袋子(zi)(zi)。可是(shi)(shi)(shi)(shi)客(ke)戶又要要求達到一定(ding)比(bi)例的(de)殘氧量，這(zhe)就很(hen)矛盾了。
