4、烘幹機生產裝置的儀器儀表
就現場使用情況來看，烘幹機裝置的控製儀器、儀表安裝設置不到位。列舉以下幾點：
4.1 糧食水分溫度在線檢測
烘幹塔有兩個出糧口，隻安裝了一隻在線水分溫度檢測儀，在負載試車中，隻能觀測到有水分、溫度在線檢測儀的出糧口，對另一個出糧口就觀測不到，不利生產操作者觀測烘後糧的水分是否一致。為了檢驗烘後糧水分、溫度的一致性，隻能在沒有安裝水分、溫wen度du測ce定ding儀yi的de出chu料liao部bu位wei，多duo次ci取qu樣yang，對dui照zhao檢jian測ce，這zhe樣yang給gei生sheng產chan管guan理li帶dai來lai許xu多duo麻ma煩fan。如ru果guo同tong樣yang安an上shang在zai線xian水shui分fen檢jian測ce儀yi，就jiu可ke以yi隨sui時shi觀guan測ce烘hong後hou玉yu米mi在zai兩liang個ge出chu料liao口kou的de水shui分fen指zhi標biao，便bian於yu指zhi導dao生sheng產chan。如ru果guo一yi個ge排pai料liao口kou有you儀yi表biao，另ling一yi個ge沒mei有you儀yi表biao，就jiu不bu容rong易yi發fa現xian糧liang食shi烘hong後hou水shui分fen的de誤wu差cha。烘hong後hou糧liang水shui分fen差cha異yi大da，進jin倉cang儲chu存cun後hou，易yi發fa生sheng壞huai糧liang。同tong時shi我wo們men認ren為wei，被bei烘hong糧liang食shi在zai進jin入ru烘hong幹gan塔ta後hou，也ye應ying對dui糧liang食shi進jin行xing在zai線xian水shui分fen檢jian測ce，這zhe樣yang，烘hong前qian烘hong後hou糧liang食shi水shui分fen能neng隨sui時shi在zai操cao作zuo儀yi表biao盤pan上shang顯xian示shi出chu來lai，操cao作zuo人ren員yuan即ji可ke根gen據ju糧liang食shi水shui分fen，調tiao整zheng和he確que定ding熱re風feng爐lu的de爐lu膛tang溫wen度du和he熱re風feng溫wen度du，確que保bao烘hong後hou糧liang食shi的de質zhi量liang。
4.2烘幹機熱風溫度控製點的位置確定
烘(hong)幹(gan)機(ji)熱(re)風(feng)溫(wen)度(du)控(kong)製(zhi)點(dian)，隻(zhi)設(she)在(zai)熱(re)風(feng)機(ji)出(chu)口(kou)管(guan)道(dao)上(shang)。對(dui)於(yu)進(jin)入(ru)各(ge)個(ge)烘(hong)幹(gan)段(duan)的(de)熱(re)風(feng)實(shi)際(ji)溫(wen)度(du)因(yin)沒(mei)有(you)控(kong)製(zhi)點(dian)，而(er)不(bu)知(zhi)道(dao)塔(ta)內(nei)各(ge)段(duan)的(de)熱(re)風(feng)溫(wen)度(du)高(gao)低(di)，因(yin)此(ci)，應(ying)當(dang)在(zai)塔(ta)體(ti)內(nei)烘(hong)幹(gan)段(duan)上(shang)、中、下3處(chu)設(she)熱(re)風(feng)溫(wen)度(du)顯(xian)示(shi)點(dian)，隨(sui)時(shi)掌(zhang)握(wo)塔(ta)內(nei)各(ge)烘(hong)幹(gan)段(duan)的(de)熱(re)風(feng)溫(wen)度(du)變(bian)化(hua)，這(zhe)樣(yang)對(dui)進(jin)入(ru)各(ge)烘(hong)幹(gan)段(duan)糧(liang)食(shi)的(de)溫(wen)度(du)可(ke)根(gen)據(ju)情(qing)況(kuang)適(shi)時(shi)進(jin)行(xing)調(tiao)整(zheng)。同(tong)時(shi)，熱(re)風(feng)爐(lu)的(de)煙(yan)道(dao)氣(qi)進(jin)入(ru)熱(re)風(feng)換(huan)熱(re)器(qi)入(ru)口(kou)、出chu口kou煙yan道dao氣qi以yi及ji進jin入ru熱re風feng換huan熱re器qi的de空kong氣qi也ye應ying設she有you溫wen度du顯xian示shi控kong製zhi點dian。這zhe樣yang就jiu可ke從cong頭tou至zhi尾wei對dui空kong氣qi換huan熱re的de熱re風feng溫wen度du進jin行xing控kong製zhi，有you利li於yu烘hong幹gan操cao作zuo。
4.3烘幹機操作控製台的圖示要細化
烘幹機操作控製台圖示不細，有的將同類控製點合並，例如除塵裝置口的4taidianjihebingweiyigegongzuoxianshidian，youdeguanjiankongzhidianhaibeifenkai，ruhonggantapailiangjigoudetiaosuxianshiyihexuanniujiushifenkaishezhide，zheyangbuliyucaozuo。zaizhenggehongganjideshengchanguochengzhong，kongzhitaitushishishengchanguanlizhongzuizhongyaodebuwei，bunenghulve。

烘hong後hou玉yu米mi經jing提ti升sheng機ji送song至zhi烘hong後hou倉cang時shi，如ru果guo烘hong後hou倉cang玉yu米mi壓ya倉cang不bu到dao位wei，隨sui來lai隨sui走zou，烘hong後hou玉yu米mi從cong高gao處chu落luo至zhi倉cang底di，會hui使shi玉yu米mi破po碎sui率lv增zeng大da，非fei常chang不bu利li於yu糧liang食shi長chang期qi保bao管guan。因yin此ci，在zai生sheng產chan操cao作zuo上shang應ying盡jin量liang避bi免mian空kong倉cang進jin糧liang。
