丹麥SAHENE旋轉(zhuǎn)閃蒸干燥機(jī)介紹
|
旋轉(zhuǎn)閃蒸干燥機(jī)(專利申請中),是專門為連續(xù)干燥的濾餅,泥漿,意大利面和纖維產(chǎn)品。每當(dāng)一個產(chǎn)品可以脫水機(jī)械之前的干燥過程(例如,由臥螺離心機(jī),離心機(jī),過濾器壓力或類似的),大幅度減少機(jī)操作的實現(xiàn)! 〔煌谄渌墮C(jī)種在市場上,不僅為無機(jī)化學(xué)品旋風(fēng)閃蒸干燥機(jī)是理想的。更多困難的產(chǎn)品,如植物為基礎(chǔ)的和肉類蛋白干燥成功在旋轉(zhuǎn)閃蒸干燥機(jī)。經(jīng)驗表明,顯著的節(jié)能效果時使用旋轉(zhuǎn)閃蒸干燥機(jī)。干燥的產(chǎn)品的瞬間閃過,大大減少了產(chǎn)品的熱量下降。這種效應(yīng)使顯著更高的工藝溫度下的使用,其結(jié)果是一個較小的機(jī)器(較低的投資)和更低的能耗(降低生產(chǎn)成本)。 對于某些產(chǎn)品,取代了傳統(tǒng)的閃蒸干燥機(jī)與一個旋轉(zhuǎn)閃蒸干燥機(jī)降低整體生產(chǎn)成本每公斤超過40%的^終粉末! ★暳袭a(chǎn)品,進(jìn)入設(shè)置有一個緩慢的旋轉(zhuǎn)攪拌器,按壓產(chǎn)品進(jìn)料螺旋輸送系統(tǒng)的進(jìn)料缸。有了一個完整的螺旋輸送器,它能夠準(zhǔn)確地控制干燥器過程。產(chǎn)品進(jìn)入到干燥室中,并通過一個快速運(yùn)動的轉(zhuǎn)子中快速崩解。產(chǎn)品表面被創(chuàng)建,并立即關(guān)閉水閃過。半干燥的粉末從解體區(qū)移動的流化區(qū)中,其中所需的殘留水分是在低溫下實現(xiàn)的。粉末和空氣通過一個可調(diào)的分類器中取出,允許一定的粒徑控制。粉末和空氣,然后采取的粉末分離系統(tǒng),通常是一個袋式過濾器用于粉末分離。通常的粉末被引入的冷卻步驟在這一點上,以閃爍前冷卻的粉末裝袋關(guān)閉。整個干燥過程是全自動的。WHIRL FLASH DRYERS The Whirl Flash dryer (patent pending) is specially designed for continuous drying of filter cakes, slurries, pastas and fibrous products. Whenever a product can be de-watered mechanically prior to the drying process (e.g. by decanters, centrifuges, filter pressess or similar), substantial reductions in dryer operations are achieved.Unlike other comparable dryer types in the market, the Whirl Flash dryer is ideal not only for inorganic chemicals. More difficult products, such as plant-based and meat proteins are dried successfully in the Whirl Flash dryer.Experience has shown significant energy savings when using the Whirl Flash dryer. The instant flash drying of the product drastically reduces the product heat degradations. This effect allows the use of significantly higher process temperature, and the consequence is a smaller dryer (lower investment) and lower energy consumption (lower production cost).For some products, replacing a traditional flash dryer with a Whirl Flash dryer reduces the overall production cost per kg final powder by over 40%.The feed product enters into a feed vat provided with a slow-rotating agitator, which presses the product down into the feed screw conveyor system. With a full screw conveyor, it is possible to accurately control the dryer process. The product enters into the drying chamber and is rapidly disintegrated by a fast moving rotor. Product surface is created, and the water is flashed off instantly. The semi-dry powder moves from the disintegration zone to the fluidization zone, where the residual moisture required is achieved at low temperature. Powder and air is taken out through an adjustable classifier, allowing certain particle size control. Powder and air is then taken to a powder separation system, typically a bag filter for powder separation. Often a powder cooling step is introduced at this point in order to flash cool the powder prior to bagging-off. The entire dryer process is fully automated.在固體制劑的生產(chǎn)工藝中,沸騰干燥機(jī)是經(jīng)常被選用的設(shè)備。沸騰干燥具有傳熱效果良好、生產(chǎn)能力大、溫度分布均勻、操作形式多樣、物料停留時間可調(diào)、投資費(fèi)用低廉和維修工作量較小等優(yōu)點。在國內(nèi)經(jīng)過30多年的使用與改進(jìn),已顯示出其在干燥領(lǐng)域的獨(dú)特地位,目前在制藥、化工、食品等方面因為很多干燥具有很大的風(fēng)險性,所以安全生產(chǎn)是流化床干燥中重要的管理目標(biāo),也是干燥工作得以順利運(yùn)行的核心要素。為了保證干燥工作的安全性,需要根據(jù)生產(chǎn)的實際需求,設(shè)計出合理的工藝流程,對于振動流化床生產(chǎn)工藝中可能存在的危險因素進(jìn)行分析判斷,做好安全控制。 1、物料的控制 材料的加工性能會為日如果流化床干燥機(jī)中的壓力被準(zhǔn)確調(diào)節(jié),過大的負(fù)壓力可能導(dǎo)致無法抽出粉末,這意味著過多的成品進(jìn)入過濾器。相反,如果負(fù)壓不足,成品會被吹出流化床式干燥機(jī)作為粉塵,污染整個系統(tǒng),從而導(dǎo)致成品的完全損失。 該解決方案用于提高工藝和更小化故障的可能性,包括一個高效的干燥過程,在該過程中,干燥空氣持續(xù)調(diào)節(jié)并具有熱風(fēng)循環(huán)烘箱已經(jīng)廣泛應(yīng)用到食品、制藥、化工等行業(yè),隨著經(jīng)濟(jì)的大步發(fā)展,熱風(fēng)循環(huán)烘箱的市場保有量也越來越大。總體來講,熱風(fēng)循環(huán)烘箱的工作非常穩(wěn)定,且使用方便,操作起來相當(dāng)簡單。但實際使用時仍然會遇到一些細(xì)節(jié)問題需要經(jīng)過大量的實踐經(jīng)驗才能掌握操作方式,比如熱風(fēng)循環(huán)烘箱如何排濕? 對于該機(jī)器的箱內(nèi)對流壁是可調(diào)式,可以調(diào)整對流壁的通風(fēng)間隙大小使溫度均勻,同時這個空載溫度均勻性是比較確定的,同時采用封閉式,有效防止熱源出去,同時在制作的時候會有嚴(yán)格的要求,這是為了保證質(zhì)量。 熱風(fēng)循環(huán)烘箱制作要求: 1、構(gòu)造設(shè)計:二門二車,常規(guī)設(shè)計,每個門內(nèi)縱向排列一輛烘車,每車24只盤,共計48
