真空包裝機廠的(de)真(zhen)(zhen)空包裝機增加充(chong)(chong)氣(qi)功能是(shi)有(you)兩種(zhong)(zhong)(zhong)方(fang)(fang)(fang)式，一(yi)種(zhong)(zhong)(zhong)是(shi)氣(qi)嘴(zui)直接(jie)伸到產品(pin)(pin)袋(dai)(dai)子里面(mian)進(jin)行充(chong)(chong)氣(qi)的(de)，另一(yi)種(zhong)(zhong)(zhong)是(shi)把要(yao)充(chong)(chong)的(de)氣(qi)體先充(chong)(chong)滿(man)整個(ge)真(zhen)(zhen)空室，然后靠負(fu)壓(ya)(ya)差充(chong)(chong)滿(man)袋(dai)(dai)子。那究竟采(cai)(cai)用哪(na)種(zhong)(zhong)(zhong)方(fang)(fang)(fang)式充(chong)(chong)氣(qi)好(hao)(hao)呢，這(zhe)里主要(yao)看客戶(hu)的(de)產品(pin)(pin)性質，單(dan)純來(lai)說肯定(ding)是(shi)直接(jie)沖到袋(dai)(dai)子里比較好(hao)(hao)，這(zhe)樣置換(huan)的(de)又純還能省不(bu)(bu)少氣(qi)源，但(dan)是(shi)大家(jia)一(yi)定(ding)要(yao)考(kao)慮好(hao)(hao)自己產品(pin)(pin)性質。如果(guo)產品(pin)(pin)是(shi)顆粒，我們(men)可(ke)以采(cai)(cai)取(qu)起初一(yi)種(zhong)(zhong)(zhong)方(fang)(fang)(fang)法直接(jie)讓充(chong)(chong)氣(qi)嘴(zui)到袋(dai)(dai)子里進(jin)行充(chong)(chong)氣(qi)，但(dan)是(shi)如果(guo)你的(de)產品(pin)(pin)是(shi)粉末狀的(de)就不(bu)(bu)能用起初一(yi)種(zhong)(zhong)(zhong)方(fang)(fang)(fang)法了(le)，需要(yao)第二種(zhong)(zhong)(zhong)在真(zhen)(zhen)空室充(chong)(chong)氣(qi)利用壓(ya)(ya)力差充(chong)(chong)滿(man)袋(dai)(dai)子。可(ke)是(shi)客戶(hu)又要(yao)要(yao)求達到一(yi)定(ding)比例(li)的(de)殘氧量(liang)，這(zhe)就很矛(mao)盾了(le)。
