真空包裝機廠(chang)的(de)真(zhen)空(kong)包裝(zhuang)機增(zeng)加(jia)充(chong)(chong)(chong)氣(qi)功(gong)能是(shi)(shi)(shi)有兩種方式(shi)，一(yi)種是(shi)(shi)(shi)氣(qi)嘴(zui)直(zhi)接伸到(dao)產(chan)品(pin)(pin)袋子里(li)面進(jin)行(xing)充(chong)(chong)(chong)氣(qi)的(de)，另一(yi)種是(shi)(shi)(shi)把要(yao)充(chong)(chong)(chong)的(de)氣(qi)體先充(chong)(chong)(chong)滿(man)整個真(zhen)空(kong)室(shi)，然后靠負壓(ya)差(cha)充(chong)(chong)(chong)滿(man)袋子。那(nei)究竟采用(yong)哪(na)種方式(shi)充(chong)(chong)(chong)氣(qi)好(hao)呢，這(zhe)里(li)主(zhu)要(yao)看客戶的(de)產(chan)品(pin)(pin)性(xing)質，單純(chun)來說(shuo)肯(ken)定(ding)(ding)是(shi)(shi)(shi)直(zhi)接沖到(dao)袋子里(li)比較好(hao)，這(zhe)樣置換的(de)又純(chun)還能省(sheng)不(bu)少氣(qi)源(yuan)，但是(shi)(shi)(shi)大(da)家(jia)一(yi)定(ding)(ding)要(yao)考(kao)慮好(hao)自己產(chan)品(pin)(pin)性(xing)質。如果產(chan)品(pin)(pin)是(shi)(shi)(shi)顆粒(li)，我們可(ke)(ke)以采取起初一(yi)種方法直(zhi)接讓充(chong)(chong)(chong)氣(qi)嘴(zui)到(dao)袋子里(li)進(jin)行(xing)充(chong)(chong)(chong)氣(qi)，但是(shi)(shi)(shi)如果你的(de)產(chan)品(pin)(pin)是(shi)(shi)(shi)粉末狀的(de)就不(bu)能用(yong)起初一(yi)種方法了，需要(yao)第二種在真(zhen)空(kong)室(shi)充(chong)(chong)(chong)氣(qi)利用(yong)壓(ya)力差(cha)充(chong)(chong)(chong)滿(man)袋子。可(ke)(ke)是(shi)(shi)(shi)客戶又要(yao)要(yao)求達到(dao)一(yi)定(ding)(ding)比例的(de)殘氧量，這(zhe)就很矛盾了。
