真(zhen)空包裝機(ji)廠(chang)的(de)真(zhen)空(kong)包裝機增加充(chong)(chong)(chong)(chong)氣(qi)(qi)功能是(shi)(shi)(shi)有兩種(zhong)方(fang)式(shi)，一種(zhong)是(shi)(shi)(shi)氣(qi)(qi)嘴直(zhi)接伸(shen)到產(chan)品袋子里(li)面進行充(chong)(chong)(chong)(chong)氣(qi)(qi)的(de)，另一種(zhong)是(shi)(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)(chong)的(de)氣(qi)(qi)體先充(chong)(chong)(chong)(chong)滿(man)(man)整個真(zhen)空(kong)室，然后靠負壓(ya)差充(chong)(chong)(chong)(chong)滿(man)(man)袋子。那究竟采用哪種(zhong)方(fang)式(shi)充(chong)(chong)(chong)(chong)氣(qi)(qi)好(hao)呢，這里(li)主要(yao)(yao)看客戶的(de)產(chan)品性(xing)質，單純來說(shuo)肯定(ding)是(shi)(shi)(shi)直(zhi)接沖到袋子里(li)比較好(hao)，這樣置(zhi)換的(de)又純還能省不少(shao)氣(qi)(qi)源，但是(shi)(shi)(shi)大家一定(ding)要(yao)(yao)考(kao)慮好(hao)自己產(chan)品性(xing)質。如(ru)果產(chan)品是(shi)(shi)(shi)顆粒，我們可(ke)以采取(qu)起初一種(zhong)方(fang)法(fa)直(zhi)接讓(rang)充(chong)(chong)(chong)(chong)氣(qi)(qi)嘴到袋子里(li)進行充(chong)(chong)(chong)(chong)氣(qi)(qi)，但是(shi)(shi)(shi)如(ru)果你(ni)的(de)產(chan)品是(shi)(shi)(shi)粉末狀的(de)就(jiu)(jiu)不能用起初一種(zhong)方(fang)法(fa)了(le)(le)，需要(yao)(yao)第(di)二種(zhong)在真(zhen)空(kong)室充(chong)(chong)(chong)(chong)氣(qi)(qi)利用壓(ya)力差充(chong)(chong)(chong)(chong)滿(man)(man)袋子。可(ke)是(shi)(shi)(shi)客戶又要(yao)(yao)要(yao)(yao)求達(da)到一定(ding)比例的(de)殘(can)氧量，這就(jiu)(jiu)很矛盾了(le)(le)。
