摘 要
谷氨酸是利用微生物发酵生产的一个具有代表性的产品,生产工艺涉及种子培养、发酵、提取、脱、离心和干燥等重要的单元操作和工程概念。通过对谷氨酸车间的工艺设计,可以加强对自己对所学知识的综合利能力。通过本毕业设计训练,可以提高自己理论联系实际的能力和工程设计方面的能力。 本设计是以精制淀粉(纯度为86%)为原料进行设计,使用一次喷射双酶法为糖化工艺,以年实际工作日300天计算,日产味精90吨。对全厂物料、热量就行衡算,对糖化工段的罐体如调浆罐、储浆罐、维持罐、层流罐、糖化罐、储糖罐以及一些标准设备如液化喷射器、板框过滤机、板式换热器和泵等进行了详细计算,以确定它们的参数,便于设备布置图的绘制。 关键词:谷氨酸钠;糖化;工艺计算
Abstract
Glutamate is produced by microbial fermentation of a representative of the products, production processes involved in seed culture, fermentation, extraction, bleaching, centrifugation and drying unit operations and other important engineering concepts.Through the workshop process design glutamate, can enhance their knowledge of the comprehensive profitability.Graduate training through the design, can improve their ability to integrate theory with practice and engineering design capabilities.
The design is based on refined starch (86% purity) as raw materials for the design, the use of a jet of two enzymes for the saccharification process, the actual working days to 300 days calculated at 90 tons of monosodium glutamate production.The whole plant material, the heat balance on the line for sugar chemical segment, such as mixing tanks tank, slurry storage tank, the maintenance tank, laminar flow tank, saccharification tanks, storage sugar and some standard equipment such as liquid jet, framefilter, plate heat exchanger and pump a detailed calculation, to determine their parameters, to facilitate the drawing of equipment layout.
Key words:glutamate;saccharification;process calculation
