節(jié)能干燥設(shè)備--（真空）槳葉干燥機(jī) （通過(guò)歐盟CE & PED認(rèn)證）
Energy Saving Drying Equipment --Vacuum Paddle Dryer (CE&PED Approved)

1.概述Descriptions:
楔型空心槳葉干燥機(jī)可對(duì)膏狀、顆粒狀、粉狀、漿狀物料間接加熱或冷卻，可完成干燥、冷卻、加熱、滅菌、反應(yīng)、低溫煅燒等單元操作。設(shè)備中特殊的楔型攪拌傳熱 槳葉，具有較高的傳熱效率和傳熱面自清潔功能。
空心軸上密集排列著楔型中空槳葉，熱介質(zhì)經(jīng)空心軸流經(jīng)槳葉。單位有效容積內(nèi)傳熱面積很大，熱介質(zhì)溫度從-40℃到320℃，可以是水蒸汽，也可以是液體型：如熱水、導(dǎo)熱油等。間接傳導(dǎo)加熱，沒(méi)有攜帶空氣帶走熱量，熱量均用來(lái)加熱物料。熱量損失僅為通過(guò)器體保溫層向環(huán)境的散熱。物料顆粒與楔型面的相對(duì)運(yùn)動(dòng)產(chǎn)生洗刷作用，能夠洗刷掉楔型面上附著物料，使運(yùn)轉(zhuǎn)中一直保持著清潔的傳熱面。槳葉干燥機(jī)的殼體為W型，殼體內(nèi)一般安排二到四根空心攪拌軸。殼體有密封端蓋與上蓋，防止物料粉塵外泄及收集物料溶劑蒸汽。出料口處設(shè)置一擋扳，保證料位高度，使傳熱面被物料覆蓋而充分發(fā)揮作用。傳熱介質(zhì)通過(guò)旋轉(zhuǎn)接頭，流經(jīng)殼體夾套及空心攪拌軸，空心攪拌軸依據(jù)熱介質(zhì)的類型而具有不同的內(nèi)部結(jié)構(gòu)，以保證******的傳熱效果。
槳葉干燥機(jī) can be used to dry or cool paste, granular, powder or starchy materials indirectly. It can carry out the processes of drying, cooling, heating, sterilization, reaction and low temperature calcination. The special paddle can help make sure of high heat transfer efficiency. Besides, the heat transfer surface has a self-cleaning function.
Paddles are lined densely on the hollow shaft. Heating resource will flow through the blades through the hollow shaft. The heat transfer surface may be very large in unit effective volume. Heat resource may be steam or liquids such as hot water or heat conducting oil with different temperatures from -40℃ to 320℃.Because of the indirect heat transfer, the air won't carry away any heat. Thus all the heat will be used for heating of materials. The only loss of heat is due to the heat dissipation from the insulating layer to the environment. The relative movement between the granules and the paddle surface will cause scrubbing, which can get rid of the attachments on the paddle surface. Thus there is always a clean heat transfer surface while the running of the machine. The 槳葉干燥機(jī) has a W-shaped housing, inside which are two to four hollow stirring shafts. The seal cover and the upper cover will prevent the powders from leaking out and at the same time collect the solvent or steam .There is a baffle at the outlet, which will make sure of a high level of material layer so that the heat transfer surface will be covered with materials and play a good role. Heat transfer medium will flow through the rotating joint, then through the shell jacket and the hollow stirring shaft. In order to make sure of a good heat transfer efficiency, the hollow stirring shafts will have different inner structures according to different types of heat transfer medium.
2. 特點(diǎn)Features：
2.1漿葉干燥機(jī)能耗低：由于間接加熱，沒(méi)有大量攜帶空氣帶走熱量，干燥器外壁又設(shè)置 保溫層，對(duì)漿狀物料，蒸發(fā)1kg水僅需1.2kg水蒸汽。
Because of the indirect heat transfer, the air won't carry away any heat. Besides, the outside shell of the dryer has a insulating layer, so it needs only 1.2kg steam to evaporate 1kg of water in slurry materials.
2.2漿葉干燥機(jī)系統(tǒng)造價(jià)低：?jiǎn)挝挥行莘e內(nèi)擁有巨大的傳熱面，就縮短了處理時(shí)間，設(shè)備尺寸變小。就極大地減少了建筑面積及建筑空間。
Low price：Because of the large heat transfer surface area in unit effective volume, a good drying efficiency can be achieved in a short time period and a small building area and space, using a relatively small machine.
2.3處理物料范圍廣：使用不同熱介質(zhì)，既可處理熱敏性物料，又可處理需高溫處理的物料。常用介質(zhì)有：水蒸汽、導(dǎo)熱油、熱水、冷卻水等。既可連續(xù)操作也可間歇操作，可在很多領(lǐng)域應(yīng)用。
A large scope of applicable materials: Using different heat transfer mediums, blade dryer can be used to dry either heat- sensitive materials or materials that require high temperature. Any of the following mediums can be used for heat transfer: steam, heat conducting oil, hot water or even cooling water. So this? machine can be used in many fields either continuously or in batch.
2.4環(huán)境污染?。翰皇褂脭y帶空氣，粉塵物料夾帶很少。物料溶劑蒸發(fā)量很小，便于處理。對(duì)有污染的物料或需回收溶劑的工況，可采用閉路循環(huán)。
Environmentally friendly: No air is used or carried, and little powder material is entrained. Besides, there is a small amount of solvent evaporation, which is easy to deal with. As for materials which may cause pollution or the situation in which the solvent needs to be returned, a closed cycle can be applied.
2.5操作費(fèi)用低：該設(shè)備正常操作，僅1小時(shí)/天·人。低速攪拌及合理的結(jié)構(gòu)。磨損量小，維修費(fèi)用很低。
Low operation cost: When the machine is operated normally, only one hour per person per day is needed. The low speed stirring way as well as the reasonable structure can make sure that there is little wear and tear and low maintenance cost.
2.6操作穩(wěn)定：由于楔型漿葉特殊的壓縮--膨脹攪拌作用，使物料顆粒充分與傳熱面接觸，在軸向區(qū)間內(nèi)，物料的溫度、濕度、混合度梯度很小，從而保證了工藝的穩(wěn)定性。
使用領(lǐng)域
Stable operation: As a result of the special compression - expansion stirring way of wedge-shaped blades, particle materials will be in full contact with the heat transfer sur face. In the axial range, there is a small gradient in material temperature, humidity and degree of mixing, which can thus make sure of a stable technology.
