葡萄糖是生物體內(nèi)新陳代謝不可短少的營養(yǎng)物質(zhì)，它的氧化反響放出的熱量是人類生命活動所需能量的重要來源，在食品、醫(yī)藥工業(yè)上可直接運用，在工業(yè)上還大量用葡萄糖為原料合成維生素C。其主要制劑產(chǎn)品是大輸液和高滲中針，由于輸液和中針的特殊給藥途徑，原料的質(zhì)量就顯得特別重要。特別是熱源反響、雜質(zhì)含量、異物等，假如沒有保證，都可能對患者形成極大的傷害。無水葡萄糖是消費輸液或中針的換代產(chǎn)品，美國及日本等國度作為注射用的葡萄糖都請求用無水葡萄糖，并在國度藥典中反映，如日本藥方規(guī)則葡萄糖注射液僅以無水糖為原料。無水葡萄糖是一水葡萄糖的更新?lián)Q代產(chǎn)品，與一水葡萄糖相比產(chǎn)品具有無熱源反響、雜質(zhì)含量少、純度高等優(yōu)點。
Glucose is an indispensable nutrient for metabolism in organisms. The heat released by its oxidation reaction is an important source of energy for human life activities. It can be directly used in food and pharmaceutical industries. In industry, it is also used as raw material to synthesize vitamin C. Its main preparation products are large transfusion and hypertonic medium needle. Because of the special route of transfusion and medium needle administration, the quality of raw materials is particularly important. Especially the heat source response, impurity content, foreign body and so on, if not guaranteed, may cause great harm to patients. Anhydrous glucose is a replacement product for infusion or mid-needle. In the United States and Japan countries, anhydrous glucose is required for injection, and it is reflected in the national pharmacopoeia, such as the Japanese Pharmacopoeia Rules that glucose injection only takes anhydrous sugar as raw material. Anhydrous glucose is a renewal product of monohydrate glucose. Compared with monohydrate glucose, the product has the advantages of no heat source, less impurity content and high purity.
在醫(yī)藥行業(yè)，應(yīng)用無水葡萄糖制成的葡萄糖注射液、葡萄糖氯化鈉注射液，可用于因某些緣由進食減少或不能進食時補充熱能；關(guān)于低血癥、饑餓性酮癥、失水等有良好的醫(yī)療效果。無水葡萄糖的消費多采用雙酶法以淀粉乳為原料，經(jīng)過液化、糖化、除渣、脫色、離交、蒸發(fā)、結(jié)晶、別離等精制處置得到一水葡萄糖，后經(jīng)溶糖、脫色、煮糖、別離、枯燥及包裝工序得到無水葡萄糖。無水葡萄糖由于不含結(jié)晶水，大大減少了雜質(zhì)及微生物的引入。無水葡萄糖消費行業(yè)中，產(chǎn)品枯燥是關(guān)鍵一步。無水葡萄糖在煮糖結(jié)晶、別離終了之后，物料水分普通在2%左右，枯燥設(shè)備效率上下，直接影響著整個消費的效率和產(chǎn)質(zhì)量量，枯燥器性能是保證產(chǎn)質(zhì)量量和節(jié)約能源的關(guān)鍵環(huán)節(jié)。
In the pharmaceutical industry, glucose injection and sodium chloride injection made of anhydrous glucose can be used to supplement heat energy when food is reduced or cannot be eaten for some reasons, and have good medical effects on hypoxemia, hunger ketosis and dehydration. The consumption of anhydrous glucose is mostly made from starch milk by double enzymatic method. After liquefaction, saccharification, slag removal, decolorization, separation, evaporation, crystallization, separation and other refined disposal, anhydrous glucose is obtained by dissolving, decolorizing, boiling, separating, drying and packaging processes. Because anhydrous glucose does not contain crystalline water, it greatly reduces the introduction of impurities and microorganisms. In anhydrous glucose consumption industry, product dryness is the key step. When anhydrous glucose is boiled and crystallized and separated, the moisture content of the material is generally about 2%. The efficiency of the drying equipment directly affects the efficiency of the whole consumption and the quality of the production. The performance of the dryer is the key link to ensure the quality of the production and save energy.
目前，無水葡萄糖消費企業(yè)產(chǎn)品的枯燥以流化床為主要枯燥設(shè)備，流化床具有維護工作量小、毛病率低、維護煩瑣、運轉(zhuǎn)牢靠等諸多優(yōu)點，但是，回混床設(shè)備操作不易控制、沸騰效果不好、單位面積產(chǎn)量低，同比，流化床枯燥效率低，不利于大范圍消費，產(chǎn)品單耗較高。
At present, fluidized bed is the main drying equipment in anhydrous glucose consumption enterprises. Fluidized bed has many advantages, such as small maintenance workload, low defect rate, cumbersome maintenance, reliable operation, etc. However, the back mixing bed equipment is not easy to control, boiling effect is not good, unit area output is low, compared with the same period, the drying efficiency of fluidized bed is low, which is not conducive to large-scale consumption and unit consumption of products. Higher.
風(fēng)機是無水葡萄糖消費枯燥過程中更重要的輔助設(shè)備之一，而更初應(yīng)用于此類枯燥系統(tǒng)的引風(fēng)機、送風(fēng)機均采用電機工頻恒速運轉(zhuǎn)方式，再經(jīng)過入口風(fēng)門擋板節(jié)流調(diào)理風(fēng)量來到達自動控制流化床體內(nèi)壓力的目的，其弊端是無法有效控制電機，無論系統(tǒng)負荷有無變化，電機均處于工頻運轉(zhuǎn)形式。這既形成了大量電能的糜費，也降低了電機的壽命，另一方面多數(shù)廠家仍采用傳統(tǒng)的控制辦法即經(jīng)過繼電器控制，這種控制方式存在著啟動電流大，運轉(zhuǎn)平安牢靠性差、能源糜費等問題。枯燥過程中，在保證枯燥送風(fēng)的干凈度的同時，將少量水分更有效率的去除掉，如何在保證枯燥效果的同時停止節(jié)能，在消費質(zhì)量跟蹤過程中還發(fā)現(xiàn)，無水葡萄糖廢品入庫后，物料溫度有上升的現(xiàn)象，極不利于貯存，也是攪擾當前消費廠家的一個問題。
Fan is one of the most important auxiliary equipments in the drying process of anhydrous glucose consumption. Initially, the induction fans and the draft fans used in this kind of drying system all adopt the constant speed operation mode of motor power frequency, and then through the throttling of the inlet valve baffle to regulate the air flow to achieve the purpose of automatic control of the internal pressure of fluidized bed. The disadvantage is that the motor can not be effectively controlled, regardless of the change of the load of the system. The motors are in the form of power frequency operation. On the other hand, most manufacturers still adopt the traditional control method, i.e. through relay control. This control method has many problems, such as large starting current, poor safety and reliability of operation, energy wastage, and so on. In the process of dryness, while ensuring the cleanliness of dry air supply, removing a small amount of moisture more efficiently. How to stop energy saving while ensuring the dryness effect? In the process of consumption quality tracking, it is also found that after the anhydrous glucose waste is put into storage, the material temperature rises, which is not conducive to storage, and is also a problem that disturbs the current consumer manufacturers.
創(chuàng)造內(nèi)容本適用新型的目的在于，克制現(xiàn)有技術(shù)的缺乏，提供了無水葡萄糖枯燥設(shè)備，一段升溫枯燥，二 段持續(xù)降溫的工藝安裝，防止了因連續(xù)枯燥形成的物料溫度高，廢品容易變色結(jié)塊的現(xiàn)象。
The purpose of creating new content is to restrain the shortage of existing technology, provide anhydrous glucose drying equipment, install one stage of heating and drying, two stages of continuous cooling process, and prevent the high temperature of materials formed by continuous drying and the phenomenon of discoloration and caking of waste products.
另外，在回混床底部設(shè)計裝置攪拌器，當發(fā)現(xiàn)回混床內(nèi)的壓力升高，物料液位上升時，開啟攪拌，保證物料的沸騰效果。
In addition, an agitator is designed at the bottom of the back mixing bed. When the pressure in the back mixing bed rises and the liquid level of the material rises, the agitator is turned on to ensure the boiling effect of the material.
普通無水葡萄糖消費企業(yè)均采用一級流化床系統(tǒng)，枯燥氣體經(jīng)過旋風(fēng)別離器后直接排入大氣。枯燥氣體溫度高，氣體中含有大量糖粉，經(jīng)過旋風(fēng)別離器后仍攜帶有較多的糖粉，直接排入大氣中，形成了嚴重的環(huán)境污染，同時，大量糖粉流失，使產(chǎn)品收率降低，形成較嚴重的糜費，不利于消費。
The ordinary anhydrous glucose consumption enterprises adopt the first-stage fluidized bed system, and the dry gas is directly discharged into the atmosphere after the cyclone separator. Dry gas has high temperature and contains a large amount of sugar powder. After cyclone separator, it still carries more sugar powder, which is directly discharged into the atmosphere, resulting in serious environmental pollution. At the same time, a large amount of sugar powder is lost, which reduces the yield of the product and forms a serious waste, which is not conducive to consumption.
