采用膜分离技术工艺制备无水结晶葡萄糖，年产300吨试验产线获得成功，并成功放大到年产2万吨。其生产工艺流程是：
Using membrane separation technology to prepare anhydrous crystalline glucose, the trial production line with an annual output of 300 tons has been successful, and successfully enlarged to an annual output of 20000 tons. The production process is as follows:
淀粉→调浆→液化→糖化→膜1→膜2→离子交换→浓缩→结晶→干燥→无水结晶葡萄糖
Starch → mixing → liquefaction → saccharification → membrane 1 → membrane 2 → ion exchange → concentration → crystallization → drying → anhydrous crystalline glucose
该集成工艺较现在工业中应用的葡萄糖生产工艺有以下几点突破：
Compared with the glucose production process applied in industry, the integrated process has the following breakthroughs:
1.采用一次喷射液化工艺，较目前通用的二次喷射液化工艺节省蒸汽6-7成，节省液化酶3-4成。
1. Compared with the current secondary jet liquefaction process, the primary jet liquefaction process can save 6-70% steam and 3-40% liquidase.
2.采用膜组合技术纯化葡萄糖糖浆，并将糖化反应与膜分离偶合起来，实现了更高的转化率，获得了更高的葡萄糖收率。
2. The glucose syrup was purified by membrane combination technology, and the saccharification reaction was coupled with membrane separation to achieve higher conversion rate and higher glucose yield.
该工艺采用两段膜过滤：一段膜过滤主要是对糖化液进行预澄清过滤处理，以去除糖化液中的非溶解性杂质，使糖化液澄清、透明，这一段过滤截留下来的物质可以经干燥制成蛋白饲料;滤出液再经二段膜过滤，以去除低聚糖和色素类杂质，所得透过液便是高纯度的葡萄糖糖液。经过这两段膜过滤后，葡萄糖的纯度可达99.9%以上，葡萄糖膜过滤收率可达99%以上。
The process adopts two-stage membrane filtration: the first stage membrane filtration is mainly to pre clarify and filter the saccharified liquid, so as to remove the insoluble impurities in the saccharified liquid and make the saccharified liquid clear and transparent. The substances retained in this stage of filtration can be dried into protein feed; The filtrate is then filtered through a two-stage membrane to remove oligosaccharides and pigment impurities. The resulting permeate is a high-purity glucose sugar solution. After the two-stage membrane filtration, the purity of glucose can reach more than 99.9%, and the yield of glucose membrane filtration can reach more than 99%.
上述膜法制备无水结晶葡萄糖的新工艺与传统工艺相比，具有很多优势：
Compared with the traditional process, the new process of preparing anhydrous crystalline glucose by the membrane method has many advantages:
一次喷射液化，降耗，两次糖化葡萄糖收率高;膜分离技术的应用，简化了传统工艺的多道工序，不仅产品质量好，而且生产成本低，经济效益好;
The application of membrane separation technology simplifies many processes of traditional technology, not only the product quality is good, but also the production cost is low and the economic benefit is good;
新工艺不用结晶就可以直接制取高纯度葡萄糖，为生产无水葡萄糖降低了成本。
The new process can directly produce high purity glucose without crystallization, which reduces the cost for the production of anhydrous glucose.
