为了进步一水葡萄糖的产量以及葡萄糖的纯度,人们提出了各种各样的方 案,例如国度学问产权文献提供一种医药用结晶葡萄糖的制法[申请号: 86106624.3],该创造的办法是运用脱支酶和葡萄糖淀粉酶与淀粉水解物作用,得到含量葡萄糖97%纯度以上的高纯度糖液,再将糖液精致浓缩,就能够制得结晶葡萄糖。上述办法固然在一定水平上进步了一水葡萄糖的产量以及葡萄糖的纯度,但是其在消费过程中,需求大量的脱支酶和葡萄糖淀粉酶,从而进步了消费的本钱,另外,运用该办法,容易产生大量的废液,容易招致环境的污染以及资源的糜费。CN201510267883.7针对上述药用葡萄糖消费办法存在消费本钱高容易产生大量的废液,从而招致环境的污染等技术问题,提出一种设计合理制备时间短消费本钱低且废液量少的药用一水葡萄糖消费工艺。包括以下步骤:
In order to improve the production of monohydrate glucose and the purity of glucose, various schemes have been proposed. For example, the National Knowledge Property Document provides a method for the preparation of crystalline glucose for medical use [Application No. 86106624.3]. The method of creation is to use debranching enzyme and glucoamylase to react with starch hydrolysate to obtain the content. Crystalline glucose can be prepared from high-purity sugar solution with 97% purity of glucose and refined concentration of the sugar solution. Although the above-mentioned method has improved the production of monohydrate glucose and the purity of glucose to a certain extent, it needs a large number of debranching enzymes and glucose amylase in the process of consumption, thus improving the cost of consumption. In addition, using this method, it is easy to produce a large number of waste liquids, which can easily lead to environmental pollution as well as environmental pollution. The waste of resources. CN201510267883.7 Aiming at the technical problems such as high consumption cost and easy to produce a large amount of waste liquor, which will cause environmental pollution, this paper proposes a process for the consumption of medicinal glucose in one water with a reasonable preparation time, low consumption cost and a small amount of waste liquor. It includes the following steps:
液化:采用二次放射工艺对玉米淀粉乳停止液化处置,详细步骤为同 时向配料罐中添加玉米淀粉乳以及相当于玉米淀粉乳1/3体积的液化酶,在添加过程中加温酶化,加温至110℃并维持1分钟;
Liquefaction: Maize starch milk was stopped liquefying by secondary irradiation. The detailed steps were adding maize starch milk and liquefying enzymes equivalent to 1/3 volume of maize starch milk to the batching tank at the same time. During the addition process, enzymatic reaction was warmed to 110 C and maintained for 1 minute.
待h步骤完毕后,然后将配料罐内的液体保送到维持罐内闪蒸 降温到95℃并维持20分钟;
After the H step is completed, the liquid in the batching tank is delivered to maintain the flash evaporation temperature in the tank to 95 C for 20 minutes.
然后将维持罐内的液体保送到蒸汽罐内,再用蒸汽加热升温 到135℃维持15秒;
Then, the liquid in the maintenance tank is delivered to the steam tank and heated to 135 C for 15 seconds.
待j步骤完毕后,将蒸汽罐罐内的液体保送到液化罐内并闪 蒸降温到93℃,再保送降温的过程中同时放射添加相当于a步骤中玉 米淀粉乳2/3体积的液化酶停止酶化,液化罐内温度维持93℃并90分 钟,完毕后,得到液化后DE值在12~14之间的玉米淀粉糖液。
After step J is completed, the liquid in the steam tank is transported to the liquefaction tank and the temperature is reduced to 93 C by flash evaporation. During the cooling process, the liquefaction enzymes equivalent to 2/3 volume of corn starch milk in step a are added to stop enzymatic hydrolysis. The temperature in the liquefaction tank is maintained at 93 C for 90 minutes. After the liquefaction, the DE value after liquefaction is obtained at 12-14 C. Between the corn starch syrup.
糖化:将d步骤得到的玉米淀粉糖液中参加糖化酶,停止糖化反响, 得到糖化液;
Saccharification: the corn starch syrup obtained in step d participates in glucoamylase, stops the reaction of saccharification, and obtains saccharification solution.

去杂质:应用转鼓过滤活性炭脱色过滤以及离子交流三种技术手腕 来去除糖化液中各种不溶性杂质以及可溶性杂质;
Impurity removal: Rotary drum filtration, activated carbon decolorization filtration and ion exchange were used to remove insoluble impurities and soluble impurities in saccharification solution.
浓缩步骤主要分为预浓缩过程以及再浓缩过程,其中预浓缩过程为: 应用MVR蒸发器将糖化液浓缩至浓度50%左右;
Concentration steps are mainly divided into pre-concentration process and re-concentration process, in which pre-concentration process is as follows: using MVR evaporator to concentrate saccharified liquid to about 50% concentration;
再浓缩过程:将预浓缩得到50%左右浓度的糖化液保送到三效废 热蒸发器停止再浓缩,得到浓度为68%-72%的浓糖浆;
Reconcentration process: Saccharification solution of about 50% concentration was pre-concentrated and sent to three-effect waste heat evaporator to stop re-concentration, and concentrated syrup of 68% - 72% concentration was obtained.

自然冷却12h后,得到结晶好的糖膏,然后将结晶好的糖膏 输入离心机内,停止离心别离,得到含水结晶葡萄糖以及剩余的浓糖 浆;
After natural cooling for 12 hours, the crystallized sugar paste was obtained, and then the crystallized sugar paste was fed into the centrifuge. The centrifugal separation was stopped and the water-containing crystalline glucose and the remaining concentrated syrup were obtained.
将剩余的浓糖浆再次添参加结晶机内,反复k步骤和l步骤, 得到含水葡萄糖结晶;
The remaining concentrated syrup was added to the crystallizer again, and the crystallization of water-containing glucose was obtained by repeating K and l steps.
