真空包裝機廠的真(zhen)空(kong)包(bao)裝機(ji)增加充(chong)(chong)(chong)(chong)氣(qi)(qi)功(gong)能是有兩種方(fang)式，一(yi)(yi)種是氣(qi)(qi)嘴直接(jie)伸到產(chan)(chan)品(pin)袋(dai)(dai)子(zi)里(li)面(mian)進行充(chong)(chong)(chong)(chong)氣(qi)(qi)的，另一(yi)(yi)種是把(ba)要(yao)充(chong)(chong)(chong)(chong)的氣(qi)(qi)體先充(chong)(chong)(chong)(chong)滿整個真(zhen)空(kong)室(shi)，然后靠負壓差(cha)充(chong)(chong)(chong)(chong)滿袋(dai)(dai)子(zi)。那究竟采用哪種方(fang)式充(chong)(chong)(chong)(chong)氣(qi)(qi)好(hao)(hao)呢，這里(li)主要(yao)看客戶的產(chan)(chan)品(pin)性(xing)質，單純來說肯定(ding)是直接(jie)沖到袋(dai)(dai)子(zi)里(li)比較好(hao)(hao)，這樣置換的又(you)(you)純還能省不(bu)少氣(qi)(qi)源(yuan)，但是大家一(yi)(yi)定(ding)要(yao)考慮好(hao)(hao)自己產(chan)(chan)品(pin)性(xing)質。如果產(chan)(chan)品(pin)是顆粒，我們(men)可(ke)以采取起初一(yi)(yi)種方(fang)法直接(jie)讓充(chong)(chong)(chong)(chong)氣(qi)(qi)嘴到袋(dai)(dai)子(zi)里(li)進行充(chong)(chong)(chong)(chong)氣(qi)(qi)，但是如果你(ni)的產(chan)(chan)品(pin)是粉末狀的就不(bu)能用起初一(yi)(yi)種方(fang)法了，需要(yao)第二種在真(zhen)空(kong)室(shi)充(chong)(chong)(chong)(chong)氣(qi)(qi)利用壓力差(cha)充(chong)(chong)(chong)(chong)滿袋(dai)(dai)子(zi)。可(ke)是客戶又(you)(you)要(yao)要(yao)求達到一(yi)(yi)定(ding)比例的殘氧(yang)量，這就很矛盾了。
