真空包裝機廠的真空包裝機(ji)增加充(chong)(chong)氣(qi)(qi)功能是(shi)(shi)有兩(liang)種(zhong)(zhong)方(fang)(fang)(fang)式，一(yi)(yi)(yi)種(zhong)(zhong)是(shi)(shi)氣(qi)(qi)嘴(zui)直(zhi)接(jie)(jie)伸到產(chan)(chan)品(pin)袋子(zi)(zi)里面進行充(chong)(chong)氣(qi)(qi)的，另一(yi)(yi)(yi)種(zhong)(zhong)是(shi)(shi)把要充(chong)(chong)的氣(qi)(qi)體先充(chong)(chong)滿(man)(man)整個真空室，然后(hou)靠負壓差(cha)充(chong)(chong)滿(man)(man)袋子(zi)(zi)。那究竟采用哪種(zhong)(zhong)方(fang)(fang)(fang)式充(chong)(chong)氣(qi)(qi)好(hao)呢，這里主要看客戶的產(chan)(chan)品(pin)性(xing)質(zhi)(zhi)，單(dan)純來說肯定(ding)是(shi)(shi)直(zhi)接(jie)(jie)沖到袋子(zi)(zi)里比較好(hao)，這樣置換(huan)的又(you)(you)純還能省不(bu)(bu)少氣(qi)(qi)源(yuan)，但(dan)(dan)是(shi)(shi)大家一(yi)(yi)(yi)定(ding)要考慮(lv)好(hao)自己產(chan)(chan)品(pin)性(xing)質(zhi)(zhi)。如果產(chan)(chan)品(pin)是(shi)(shi)顆(ke)粒，我們可以采取(qu)起(qi)初一(yi)(yi)(yi)種(zhong)(zhong)方(fang)(fang)(fang)法(fa)直(zhi)接(jie)(jie)讓充(chong)(chong)氣(qi)(qi)嘴(zui)到袋子(zi)(zi)里進行充(chong)(chong)氣(qi)(qi)，但(dan)(dan)是(shi)(shi)如果你的產(chan)(chan)品(pin)是(shi)(shi)粉末狀(zhuang)的就不(bu)(bu)能用起(qi)初一(yi)(yi)(yi)種(zhong)(zhong)方(fang)(fang)(fang)法(fa)了，需要第(di)二種(zhong)(zhong)在真空室充(chong)(chong)氣(qi)(qi)利用壓力差(cha)充(chong)(chong)滿(man)(man)袋子(zi)(zi)。可是(shi)(shi)客戶又(you)(you)要要求達(da)到一(yi)(yi)(yi)定(ding)比例的殘(can)氧量，這就很矛盾了。
