我wo們men知zhi道dao，容rong重zhong指zhi的de是shi單dan位wei體ti積ji內nei的de重zhong量liang，玉yu米mi的de容rong重zhong是shi一yi升sheng的de玉yu米mi在zai標biao準zhun的de容rong重zhong器qi實shi驗yan下xia的de重zhong量liang，反fan映ying了le玉yu米mi籽zi粒li的de飽bao滿man程cheng度du。是shi糧liang食shi收shou購gou行xing業ye為wei玉yu米mi定ding等deng定ding價jia的de重zhong要yao依yi據ju。影ying響xiang著zhe玉yu米mi的de運yun輸shu效xiao率lv和he倉cang儲chu效xiao率lv。一yi般ban來lai說shuo，玉yu米mi容rong重zhong越yue大da
，所suo占zhan用yong的de容rong積ji越yue小xiao
，相xiang應ying的de，運yun輸shu效xiao率lv和he倉cang儲chu效xiao率lv就jiu會hui越yue高gao。大da家jia可ke以yi利li用yong托tuo普pu雲yun農nong生sheng產chan的deGHCS-1000A玉米容重器測定玉米容重。

    該gai玉yu米mi容rong重zhong器qi是shi根gen據ju新xin國guo標biao中zhong測ce量liang糧liang食shi容rong重zhong要yao求qiu而er研yan製zhi。具ju備bei可ke充chong電dian功gong能neng。采cai用yong電dian子zi稱cheng重zhong技ji術shu和he計ji算suan機ji技ji術shu，實shi現xian了le在zai顯xian示shi稱cheng重zhong結jie果guo的de同tong時shi自zi動dong打da印yin測ce試shi結jie果guo。該gai儀yi器qi廣guang泛fan應ying用yong於yu小xiao麥mai、稻穀、高粱、玉米等農作物的容重測量。
    使shi用yong玉yu米mi容rong重zhong器qi測ce定ding玉yu米mi的de容rong重zhong時shi，首shou先xian要yao製zhi備bei樣yang品pin，清qing除chu其qi中zhong的de雜za質zhi
，然ran後hou將jiang製zhi備bei的de試shi樣yang倒dao入ru穀gu物wu筒tong中zhong
，裝zhuang滿man刮gua平ping。再zai將jiang穀gu物wu筒tong套tao在zai中zhong間jian筒tong上shang，打da開kai漏lou鬥dou開kai關guan，讓rang玉yu米mi自zi由you下xia落luo
，待dai試shi樣yang全quan部bu經jing過guo中zhong間jian筒tong落luo入ru容rong量liang筒tong後hou，關guan閉bi漏lou鬥dou開kai關guan。用yong手shou握wo住zhu穀gu物wu筒tong與yu中zhong間jian筒tong的de接jie全quan處chu
，將jiang插cha片pian準zhun確que地di插cha入ru豁huo口kou槽cao中zhong
，依yi次ci取qu下xia穀gu物wu筒tong，拿na起qi中zhong間jian筒tong和he容rong量liang筒tong
，倒dao淨jing插cha片pian上shang多duo餘yu的de試shi樣yang
，抽chou出chu插cha片pian，取qu下xia容rong量liang筒tong上shang的de鐵tie板ban底di座zuo
，將jiang容rong量liang筒tong放fang在zai電dian子zi秤cheng上shang稱cheng量liang。雙shuang試shi驗yan允yun許xu差cha不bu超chao過guo3g/L，求其平均數，即為測定結果。
