真空(kong)包裝機廠的真(zhen)(zhen)(zhen)空(kong)包(bao)裝機(ji)增加充(chong)(chong)(chong)(chong)氣功(gong)能是(shi)有(you)兩種方(fang)式，一(yi)種是(shi)氣嘴直(zhi)接伸到產(chan)品(pin)袋(dai)子(zi)里(li)面進(jin)行充(chong)(chong)(chong)(chong)氣的，另一(yi)種是(shi)把要充(chong)(chong)(chong)(chong)的氣體先充(chong)(chong)(chong)(chong)滿(man)(man)整個真(zhen)(zhen)(zhen)空(kong)室(shi)，然后靠(kao)負壓(ya)差(cha)充(chong)(chong)(chong)(chong)滿(man)(man)袋(dai)子(zi)。那究竟(jing)采(cai)用哪種方(fang)式充(chong)(chong)(chong)(chong)氣好(hao)呢(ni)，這里(li)主要看客戶的產(chan)品(pin)性質，單(dan)純來說肯定是(shi)直(zhi)接沖到袋(dai)子(zi)里(li)比較好(hao)，這樣置換的又純還能省不少氣源，但(dan)是(shi)大家一(yi)定要考慮(lv)好(hao)自(zi)己產(chan)品(pin)性質。如果(guo)產(chan)品(pin)是(shi)顆粒，我們(men)可以采(cai)取起初一(yi)種方(fang)法直(zhi)接讓(rang)充(chong)(chong)(chong)(chong)氣嘴到袋(dai)子(zi)里(li)進(jin)行充(chong)(chong)(chong)(chong)氣，但(dan)是(shi)如果(guo)你的產(chan)品(pin)是(shi)粉末狀的就不能用起初一(yi)種方(fang)法了，需要第(di)二(er)種在真(zhen)(zhen)(zhen)空(kong)室(shi)充(chong)(chong)(chong)(chong)氣利用壓(ya)力差(cha)充(chong)(chong)(chong)(chong)滿(man)(man)袋(dai)子(zi)。可是(shi)客戶又要要求達到一(yi)定比例的殘氧量(liang)，這就很(hen)矛盾了。
