工業(yè)葡萄糖菌種培養(yǎng)的工藝操作流程：
The main operation process of industrial glucose is as follows:
①調和淀粉漿：取紅薯淀粉25干克置于糖化鍋中，然后取濃硫酸2.1千克緩緩加入2千克水中攪勻，再將此稀酸液倒入糖化鍋中攪勻。另取沸水75千克迅速加入其中，攪成漿糊狀。
① Blending starch slurry: take 25 dry grams of sweet potato starch and put it in the saccharification pot, then take 2.1kg of concentrated sulfuric acid and slowly add 2kg of water to mix well, and then pour the dilute acid into the saccharification pot and mix well. Another 75 kg of boiling water is quickly added to it and stirred into a paste.
②糖化：將淀粉漿溫度升98℃并保持-4小時，然后吸取少量糖化液，滴人碘液檢驗糖化終點。糖化結束后;停止加熱，濾去殘渣，濾液待下一步處理。
② Saccharification: raise the temperature of starch slurry to 98 ℃ and keep it for - 4 hours, then absorb a small amount of saccharification liquid and drop iodine solution to check the end point of saccharification. After saccharification, stop heating, filter the residue, and the filtrate will be treated in the next step.
③中和：在濾液中約加3.8千克碳酸鈣，對其進行中和，邊加邊攪動，然后將糖液再加熱85℃，保持半小時，用布過濾，除去硫酸鈣。
③ Neutralization: add about 3.8kg calcium carbonate to the filtrate to neutralize it, stir it while adding, then heat the sugar solution to 85 ℃ for half an hour, and filter it with cloth to remove calcium sulfate.
④脫色：取上面已中和好的澄清濾液，加熱85℃，然后按濾液重量加入0.3%的活性炭保持85℃半小時，然后乘熱過濾除去活性炭。起初流下來的帶有微量活性炭，另器接濾，濾清再用清潔之容器接存。
④ Decolorization: take the above neutralized clarified filtrate, heat it to 85 ℃, then add 0.3% activated carbon according to the weight of filtrate, keep it at 85 ℃ for half an hour, and then remove the activated carbon by thermal filtration. At the beginning of the flow down with a trace of activated carbon, another filter, to filter and then clean the container storage.
⑤蒸發(fā)：蒸發(fā)過程即是糖液濃縮過程號將糖液的部分水分蒸去，25℃測定比重為1.3時，即可進行結晶。
⑤ Evaporation: the evaporation process is the sugar concentration process. Part of the water in the sugar is evaporated. When the specific gravity is 1.3 at 25 ℃, crystallization can be carried out.
⑥結晶：按已蒸濃的糖，液重量加入0.5%-l.0%的葡萄糖晶種
⑥ Crystallization: add 0.5% - 1.0% glucose seed according to the weight of concentrated sugar
工業(yè)葡萄糖在調試及運轉進程有許多影響處置效果的要素,首要有進水COD濃度、pH值、溫度、溶解氧等,所以對整個體系經過感官判別和化學剖析辦法進行監(jiān)測是必不可少的。依據監(jiān)測剖析的成果對影響要素進行調整，使處置到達效果。
There are many factors affecting the treatment effect of industrial glucose in the process of commissioning and operation, such as influent COD concentration, pH value, temperature, dissolved oxygen, etc. According to the results of monitoring and analysis, the influencing factors are adjusted to achieve the effect of disposal.
