1、摘要在木設(shè)計(jì)中高麥芽糖漿的生產(chǎn)方法是利用淀粉為原料，通過(guò)二次噴射液化、糖化、脫色過(guò)濾、離子交換、濃縮等工藝過(guò)程，制成濃度為75%的高麥芽糖漿。本次工藝采用的是雙酶法，這種工藝不但提高了麥芽糖的產(chǎn)量和淀粉的利用率，而且使生產(chǎn)成本大大降低。高麥芽糖漿的優(yōu)點(diǎn)有很多比如較高的保濕性和較低的吸潮性，口味相對(duì)適中的甜度，比較良好的抗結(jié)品與抗氧化性，適屮的粘度，穩(wěn)定的化學(xué)性質(zhì)，冰點(diǎn)低，較高的耐熱性就算在加熱時(shí)也不容易發(fā)生美拉德反應(yīng)等。這些優(yōu)點(diǎn)使它被廣泛的應(yīng)用于食品、保健、化工等多種行業(yè)，尤蘇是在食品工業(yè)中，可提高食品的粘稠度和UI感這一特性使它在甜品、冷飲、糖果、乳品等食品加工行業(yè)中被青睞。國(guó)際
2、上目前利用酶法生產(chǎn)高麥芽糖漿是較為先進(jìn)的方法之一，其中除了糖化酶和固定化液化酶的生產(chǎn)工藝外，還有熱分離水化系統(tǒng)精制麥芽糖漿以及超濾法等。目前國(guó)內(nèi)外酶法生產(chǎn)高麥芽糖漿仍處于主流位置。因酶法生產(chǎn)不僅成本低，生產(chǎn)較安全且生產(chǎn)效益高。本設(shè)計(jì)通過(guò)對(duì)國(guó)內(nèi)外文獻(xiàn)的杳閱最終也采用酶法來(lái)進(jìn)行高麥芽糖漿的生產(chǎn)。在本次設(shè)計(jì)屮主要是對(duì)生產(chǎn)流程屮所需各種物料平衡的計(jì)算、熱量平衡的計(jì)算、水平衡的計(jì)算、本設(shè)計(jì)重點(diǎn)工段（蒸發(fā)工段）的論證和設(shè)計(jì)以及設(shè)備選型等。關(guān)鍵詞：高麥芽糖漿；雙酶法；工藝；計(jì)算AbstractInthedesignofhighmaltosesyrupistheuseofstarchasrawma
