真空包裝機廠(chang)的(de)真空(kong)包裝機增加充(chong)(chong)氣(qi)功能是(shi)(shi)(shi)有兩種(zhong)方式(shi)，一種(zhong)是(shi)(shi)(shi)氣(qi)嘴直(zhi)接伸到產品袋(dai)(dai)子里面進(jin)(jin)行充(chong)(chong)氣(qi)的(de)，另一種(zhong)是(shi)(shi)(shi)把要充(chong)(chong)的(de)氣(qi)體先(xian)充(chong)(chong)滿(man)整個真空(kong)室，然后靠負壓差(cha)充(chong)(chong)滿(man)袋(dai)(dai)子。那究竟采用哪種(zhong)方式(shi)充(chong)(chong)氣(qi)好(hao)呢，這里主要看客戶的(de)產品性質，單(dan)純來說肯定是(shi)(shi)(shi)直(zhi)接沖到袋(dai)(dai)子里比較好(hao)，這樣(yang)置換的(de)又(you)純還(huan)能省不(bu)(bu)少氣(qi)源，但是(shi)(shi)(shi)大家一定要考(kao)慮好(hao)自己產品性質。如果(guo)產品是(shi)(shi)(shi)顆粒，我(wo)們可以采取(qu)起初一種(zhong)方法(fa)直(zhi)接讓充(chong)(chong)氣(qi)嘴到袋(dai)(dai)子里進(jin)(jin)行充(chong)(chong)氣(qi)，但是(shi)(shi)(shi)如果(guo)你(ni)的(de)產品是(shi)(shi)(shi)粉末狀的(de)就不(bu)(bu)能用起初一種(zhong)方法(fa)了，需(xu)要第二種(zhong)在真空(kong)室充(chong)(chong)氣(qi)利用壓力差(cha)充(chong)(chong)滿(man)袋(dai)(dai)子。可是(shi)(shi)(shi)客戶又(you)要要求(qiu)達到一定比例(li)的(de)殘氧(yang)量，這就很矛(mao)盾了。
