真空(kong)包裝機(ji)廠的(de)(de)(de)真(zhen)(zhen)空包裝機增加充(chong)(chong)氣功能是(shi)有兩種(zhong)(zhong)方式(shi),一種(zhong)(zhong)是(shi)氣嘴直接(jie)伸到(dao)產(chan)(chan)品袋(dai)子里(li)面進行(xing)充(chong)(chong)氣的(de)(de)(de),另(ling)一種(zhong)(zhong)是(shi)把要(yao)(yao)充(chong)(chong)的(de)(de)(de)氣體(ti)先充(chong)(chong)滿整(zheng)個真(zhen)(zhen)空室(shi),然后靠負壓差(cha)充(chong)(chong)滿袋(dai)子。那究(jiu)竟采用哪(na)種(zhong)(zhong)方式(shi)充(chong)(chong)氣好(hao)呢(ni),這(zhe)里(li)主要(yao)(yao)看客戶(hu)的(de)(de)(de)產(chan)(chan)品性質(zhi),單純(chun)來(lai)說肯(ken)定是(shi)直接(jie)沖(chong)到(dao)袋(dai)子里(li)比較好(hao),這(zhe)樣置換的(de)(de)(de)又(you)純(chun)還能省(sheng)不(bu)少氣源(yuan),但是(shi)大家(jia)一定要(yao)(yao)考慮好(hao)自己產(chan)(chan)品性質(zhi)。如果產(chan)(chan)品是(shi)顆粒,我們(men)可(ke)以采取起初一種(zhong)(zhong)方法直接(jie)讓(rang)充(chong)(chong)氣嘴到(dao)袋(dai)子里(li)進行(xing)充(chong)(chong)氣,但是(shi)如果你的(de)(de)(de)產(chan)(chan)品是(shi)粉末狀的(de)(de)(de)就(jiu)不(bu)能用起初一種(zhong)(zhong)方法了,需要(yao)(yao)第(di)二(er)種(zhong)(zhong)在真(zhen)(zhen)空室(shi)充(chong)(chong)氣利用壓力(li)差(cha)充(chong)(chong)滿袋(dai)子。可(ke)是(shi)客戶(hu)又(you)要(yao)(yao)要(yao)(yao)求達到(dao)一定比例的(de)(de)(de)殘氧量,這(zhe)就(jiu)很矛盾了。
