　　采用膜分離技術(shù)工藝制備無水結(jié)晶葡萄糖，年產(chǎn)300噸試驗(yàn)產(chǎn)線獲得成功，并成功放大到年產(chǎn)2萬噸。其生產(chǎn)工藝流程是：

　　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→調(diào)漿→液化→糖化→膜1→膜2→離子交換→濃縮→結(jié)晶→干燥→無水結(jié)晶葡萄糖

　　Starch → mixing → liquefaction → saccharification → membrane 1 → membrane 2 → ion exchange → concentration → crystallization → drying → anhydrous crystalline glucose

　　該集成工藝較現(xiàn)在工業(yè)中應(yīng)用的葡萄糖生產(chǎn)工藝有以下幾點(diǎn)突破：

　　Compared with the glucose production process applied in industry, the integrated process has the following breakthroughs:

　　1.采用一次噴射液化工藝，較目前通用的二次噴射液化工藝節(jié)省蒸汽6-7成，節(jié)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.采用膜組合技術(shù)純化葡萄糖糖漿，并將糖化反應(yīng)與膜分離偶合起來，實(shí)現(xiàn)了更高的轉(zhuǎn)化率，獲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.

　　該工藝采用兩段膜過濾：一段膜過濾主要是對(duì)糖化液進(jìn)行預(yù)澄清過濾處理，以去除糖化液中的非溶解性雜質(zhì)，使糖化液澄清、透明，這一段過濾截留下來的物質(zhì)可以經(jīng)干燥制成蛋白飼料;濾出液再經(jīng)二段膜過濾，以去除低聚糖和色素類雜質(zhì)，所得透過液便是高純度的葡萄糖糖液。經(jīng)過這兩段膜過濾后，葡萄糖的純度可達(dá)99.9%以上，葡萄糖膜過濾收率可達(dá)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%.

　　上述膜法制備無水結(jié)晶葡萄糖的新工藝與傳統(tǒng)工藝相比，具有很多優(yōu)勢(shì)：

　　Compared with the traditional process, the new process of preparing anhydrous crystalline glucose by the membrane method has many advantages:

　　一次噴射液化，降耗，兩次糖化葡萄糖收率高;膜分離技術(shù)的應(yīng)用，簡(jiǎn)化了傳統(tǒng)工藝的多道工序，不僅產(chǎn)品質(zhì)量好，而且生產(chǎn)成本低，經(jīng)濟(jì)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;

　　新工藝不用結(jié)晶就可以直接制取高純度葡萄糖，為生產(chǎn)無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.
