真空包裝機廠的真空包裝機(ji)增加充(chong)(chong)氣(qi)(qi)功能(neng)是(shi)(shi)有兩種(zhong)(zhong)方式，一(yi)種(zhong)(zhong)是(shi)(shi)氣(qi)(qi)嘴直(zhi)接伸到產(chan)品(pin)袋(dai)(dai)子(zi)(zi)里(li)(li)面進(jin)(jin)行(xing)充(chong)(chong)氣(qi)(qi)的，另一(yi)種(zhong)(zhong)是(shi)(shi)把要(yao)(yao)充(chong)(chong)的氣(qi)(qi)體先(xian)充(chong)(chong)滿整個真空室，然(ran)后(hou)靠負(fu)壓(ya)差充(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。那究竟采用哪種(zhong)(zhong)方式充(chong)(chong)氣(qi)(qi)好呢(ni)，這(zhe)里(li)(li)主(zhu)要(yao)(yao)看客戶的產(chan)品(pin)性(xing)質，單純(chun)來說肯定(ding)(ding)是(shi)(shi)直(zhi)接沖到袋(dai)(dai)子(zi)(zi)里(li)(li)比(bi)較好，這(zhe)樣(yang)置換的又純(chun)還能(neng)省(sheng)不少氣(qi)(qi)源，但是(shi)(shi)大家一(yi)定(ding)(ding)要(yao)(yao)考慮好自(zi)己產(chan)品(pin)性(xing)質。如(ru)果產(chan)品(pin)是(shi)(shi)顆粒(li)，我(wo)們可(ke)(ke)以采取起(qi)初一(yi)種(zhong)(zhong)方法(fa)直(zhi)接讓充(chong)(chong)氣(qi)(qi)嘴到袋(dai)(dai)子(zi)(zi)里(li)(li)進(jin)(jin)行(xing)充(chong)(chong)氣(qi)(qi)，但是(shi)(shi)如(ru)果你(ni)的產(chan)品(pin)是(shi)(shi)粉末狀的就(jiu)不能(neng)用起(qi)初一(yi)種(zhong)(zhong)方法(fa)了(le)，需要(yao)(yao)第(di)二(er)種(zhong)(zhong)在(zai)真空室充(chong)(chong)氣(qi)(qi)利(li)用壓(ya)力差充(chong)(chong)滿袋(dai)(dai)子(zi)(zi)。可(ke)(ke)是(shi)(shi)客戶又要(yao)(yao)要(yao)(yao)求(qiu)達到一(yi)定(ding)(ding)比(bi)例的殘氧量，這(zhe)就(jiu)很矛盾了(le)。
