真空包裝機(ji)廠的(de)(de)真(zhen)空包裝機增加充(chong)氣(qi)(qi)(qi)功能是(shi)有兩種(zhong)(zhong)(zhong)方(fang)式，一(yi)種(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)(qi)嘴直(zhi)接(jie)伸到產品(pin)(pin)(pin)袋(dai)(dai)子(zi)里面(mian)進(jin)行充(chong)氣(qi)(qi)(qi)的(de)(de)，另(ling)一(yi)種(zhong)(zhong)(zhong)是(shi)把要充(chong)的(de)(de)氣(qi)(qi)(qi)體先充(chong)滿整個真(zhen)空室，然后靠(kao)負壓(ya)差充(chong)滿袋(dai)(dai)子(zi)。那究竟采用(yong)(yong)哪種(zhong)(zhong)(zhong)方(fang)式充(chong)氣(qi)(qi)(qi)好(hao)呢，這(zhe)里主要看客(ke)戶的(de)(de)產品(pin)(pin)(pin)性質(zhi)(zhi)，單純來說肯(ken)定(ding)是(shi)直(zhi)接(jie)沖到袋(dai)(dai)子(zi)里比較(jiao)好(hao)，這(zhe)樣置換的(de)(de)又(you)(you)純還能省不少氣(qi)(qi)(qi)源，但是(shi)大家(jia)一(yi)定(ding)要考慮(lv)好(hao)自己產品(pin)(pin)(pin)性質(zhi)(zhi)。如果(guo)產品(pin)(pin)(pin)是(shi)顆粒(li)，我們可以(yi)采取起初一(yi)種(zhong)(zhong)(zhong)方(fang)法直(zhi)接(jie)讓充(chong)氣(qi)(qi)(qi)嘴到袋(dai)(dai)子(zi)里進(jin)行充(chong)氣(qi)(qi)(qi)，但是(shi)如果(guo)你的(de)(de)產品(pin)(pin)(pin)是(shi)粉末狀的(de)(de)就(jiu)不能用(yong)(yong)起初一(yi)種(zhong)(zhong)(zhong)方(fang)法了，需要第二(er)種(zhong)(zhong)(zhong)在真(zhen)空室充(chong)氣(qi)(qi)(qi)利(li)用(yong)(yong)壓(ya)力差充(chong)滿袋(dai)(dai)子(zi)。可是(shi)客(ke)戶又(you)(you)要要求達(da)到一(yi)定(ding)比例的(de)(de)殘氧量(liang)，這(zhe)就(jiu)很矛盾了。
