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(qǐng)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(gè)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(shí)現(xiàn)! 〔煌谄渌(jí)機(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(yàn)表明,顯著的節(jié)能效果時(shí)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(gè)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(duì)于某些產(chǎn)品,取代了傳統(tǒng)的閃蒸干燥機(jī)與一個(gè)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(gè)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(gè)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(gè)快速運(yùn)動(dòng)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(dòng)的流化區(qū)中,其中所需的殘留水分是在低溫下實(shí)現(xiàn)的。粉末和空氣通過一個(gè)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(gè)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(diǎn)上,以閃爍前冷卻的粉末裝袋關(guān)閉。整個(gè)干燥過程是全自動(dòng)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.一 、概述 FG型高效沸騰干燥機(jī)是目前GMP醫(yī)藥工程設(shè)計(jì)中與YK搖擺式顆粒機(jī)和GHL型高速混合制粒機(jī)配套的顆粒高效干燥裝置,其具有比傳統(tǒng)臥式XF沸騰干燥機(jī)更寬的流化范圍,且易于清洗。物料在流化的同時(shí)被低速攪拌,因而避免結(jié)塊,對(duì)于含濕量偏高、帶粘性物料,其運(yùn)用優(yōu)勢特別突出。二、技術(shù)參數(shù)型號(hào)項(xiàng)振動(dòng)流化床技術(shù)是把振動(dòng)能量引入普通流化床以達(dá)到改善流化質(zhì)量的氣固流態(tài)技術(shù),它可以在很低的流化氣速下形成均勻的流化狀態(tài)。由于顆粒的脈沖跳動(dòng),加強(qiáng)了氣固、固固之間的接觸,減少了粘結(jié)機(jī)會(huì),提高了傳遞速率,強(qiáng)化了生產(chǎn)過程! ≡谡駝(dòng)流化床使用過程中出現(xiàn)了冒煙現(xiàn)象我們該如何處理: 1、籠型轉(zhuǎn)子斷條或 通過在流化床系統(tǒng)中進(jìn)行噴涂,即使使用薄膜材料,也能為產(chǎn)品提供^佳的表面涂層;根據(jù)要求,可以影響和增強(qiáng)產(chǎn)品屬性;用這種方法,不同形狀和尺寸的顆粒都可在流化床中移動(dòng)并同時(shí)噴射液體。水溶液或有機(jī)溶液蒸發(fā)并且其包含的固體形成涂層,典型的粒徑為100微米至3毫米。 &emsp我國干燥機(jī)較原始的干燥機(jī)就是常溫來干燥的,這是較經(jīng)典的干燥機(jī)一種,在現(xiàn)在的生活中較常見和經(jīng)濟(jì)實(shí)惠的干燥方法還是溫通風(fēng)干燥機(jī),經(jīng)典還是不一樣。 常溫通風(fēng)干燥機(jī) 由干燥倉和風(fēng)機(jī)熱風(fēng)循環(huán)烘箱溫度過沖太大是指第一次開機(jī)時(shí),工作溫度超過設(shè)定溫度3℃以上后,再慢慢降低并穩(wěn)定在目標(biāo)溫度上的現(xiàn)象。一些醫(yī)藥、生物、化工、食品、電子等行業(yè)對(duì)這種現(xiàn)象是比較敏感的! 氐紫郎囟冗^沖是不可能的。使溫度過沖達(dá)到可以接受的程度是有辦法的。對(duì)于以前購買產(chǎn)品的用戶來講,這里有3種辦法可供用戶選擇:
