玉米是主要的糧食作物之一,是制造淀粉的主要原料.在淀粉生產中除生產精制玉米淀粉外,其它副產品還有:玉米纖維12.5%、蛋5.5%、濃縮玉米漿12%、玉米胚芽6%（含玉米油2.5%）。另外，玉米淀粉經進一步加工可生產糊精、變性淀粉、淀粉糖、酒精、乳酸、味精等。蛋白閃蒸干燥設備

玉(yu)米(mi)淀粉生(sheng)產線采用(yong)玉(yu)米(mi)濕(shi)磨工(gong)藝和閉環(huan)流程，具(ju)有技術先(xian)進、成(cheng)熟(shu)可(ke)靠等特點(dian)，所生(sheng)產的玉(yu)米(mi)淀粉雜質少(shao)、質量(liang)高，是(shi)食品、醫(yi)藥、紡織、造紙、化工(gong)等行業不可(ke)缺少(shao)的重要原料。

玉米淀粉生產線工藝

1.玉米貯存與凈化

原料玉(yu)(yu)米(mi)(要求成(cheng)熟的(de)玉(yu)(yu)米(mi)，不(bu)能用高(gao)溫(wen)干燥過(guo)熱的(de)玉(yu)(yu)米(mi))經(jing)地(di)秤(cheng)計量后卸入玉(yu)(yu)米(mi)料斗，經(jing)輸送(song)機、斗式提升(sheng)機進入原料貯倉(cang)(cang)(cang)，經(jing)振動篩選、除石(shi)、磁選等工序凈化(hua)，計量后去凈化(hua)玉(yu)(yu)米(mi)倉(cang)(cang)(cang)。由玉(yu)(yu)米(mi)倉(cang)(cang)(cang)出來的(de)玉(yu)(yu)米(mi)用水力或機械(xie)輸送(song)去浸泡系統(tong)。

2.玉米浸泡

玉(yu)(yu)(yu)米的(de)(de)浸(jin)(jin)(jin)泡(pao)(pao)是(shi)在(zai)亞(ya)水溶(rong)液(ye)(ye)中逆流進行(xing)的(de)(de)。一(yi)般采用半連續(xu)流程。浸(jin)(jin)(jin)泡(pao)(pao)罐(guan)(guan)８-１２個，浸(jin)(jin)(jin)泡(pao)(pao)過程中玉(yu)(yu)(yu)米留在(zai)罐(guan)(guan)內(nei)(nei)(nei)靜止，用泵將浸(jin)(jin)(jin)泡(pao)(pao)液(ye)(ye)在(zai)罐(guan)(guan)內(nei)(nei)(nei)一(yi)邊(bian)自身循環一(yi)邊(bian)向(xiang)前一(yi)級罐(guan)(guan)內(nei)(nei)(nei)輸送，始(shi)終保(bao)(bao)持(chi)新(xin)的(de)(de)亞(ya)溶(rong)液(ye)(ye)與浸(jin)(jin)(jin)泡(pao)(pao)時間長(即將結(jie)束浸(jin)(jin)(jin)泡(pao)(pao))的(de)(de)玉(yu)(yu)(yu)米接觸，而(er)新(xin)入罐(guan)(guan)的(de)(de)玉(yu)(yu)(yu)米與即將排出的(de)(de)浸(jin)(jin)(jin)泡(pao)(pao)液(ye)(ye)接觸，從而(er)保(bao)(bao)持(chi)佳的(de)(de)浸(jin)(jin)(jin)泡(pao)(pao)效果(guo)。完成浸(jin)(jin)(jin)泡(pao)(pao)的(de)(de)浸(jin)(jin)(jin)泡(pao)(pao)液(ye)(ye)即稀玉(yu)(yu)(yu)米漿含(han)干物(wu)質７%-９%，送到蒸發工序濃縮成含(han)干物(wu)質４０的(de)(de)玉(yu)(yu)(yu)米漿。
