本文從檸檬酸及其用途，總體工藝建設(shè)方案，原料及其處理，發(fā)酵及醪液處理工藝，粗提與精制工藝蒸發(fā)、結(jié)晶、分離、干燥等幾個(gè)方面，簡(jiǎn)介工藝設(shè)計(jì)中的基本方法。在本工程的設(shè)計(jì)中，原料處理及發(fā)酵工 藝的確定。因而采用了玉米干法脫胚粉碎或薯干直接粉碎調(diào)漿、液化 (玉米液化漿 )壓濾、低壓連續(xù)噴射滅菌，液體深層發(fā)酵的工藝路線。 關(guān)鍵詞： 檸檬酸 無(wú)水檸檬酸 工藝設(shè)計(jì) 深加工 Abstract In this paper, and the use of citric acid, the overall technology development programs, materials and processing, mash fermentation and processing technology, the crude and the refining process evaporation, crystallization, separation, drying areas, briefing the basic method of process design. In the project design, materials processing and fermentation process to determine. We must bine the local characteristics of raw materials, but also the strength of existing technologies, production technology to route not only to adapt to the dry matte
