閃蒸干燥機 基爾M / S奈良機械公司，日本，閃蒸干燥器在世界上的^制造商的技術合作，生產閃蒸干燥器。這種設計使用懸浮顆粒表面的材料中的水分迅速除去的固體顆粒分散在加熱的氣體/空氣流的干燥技術。操作原理這個詞閃蒸是指瞬時或快速干燥的產品。有五種主要因素支配的干燥速度。這些是：1。水分分布 這被定義為潮濕的表面的干燥介質（熱空氣或氣體）中的可訪問性。這是通過使用分散機如機械散射體，雙槳饋線或籠式磨機等，通過混合在飼料中的干燥產物的產物在閃蒸干燥器實現。2。溫度差 在閃蒸干燥，它是可能的，使用高的初始溫度。這些都可能是由于接觸時間短的結果，產品的溫度從未超過氣體的濕球溫度，除非所有的表面水分除去。3。 AGITATION 在閃蒸干燥機，攪拌或湍流是通過使用高氣體速度。蒸汽膜不斷卷走從潮濕的顆粒。其結果是，除去水分幾乎是瞬時的。4。顆粒結構 具有毛細管的材料將能夠更迅速地得到的迅速干燥作用中的內部區域的表面自進化水分。有沒有空隙的致密顆粒，是很難干燥，在一個閃蒸干燥系統。5。顆粒尺寸 通過蒸發從粒子的表面來完成干燥。因此，要除去的內部的水分，這是必要的水分通過擴散到達表面。這一轉移將明顯發生^迅速，更小的顆粒。典型布置 若干安排是可能的單獨的應用程序，以適應規范。少數的安排都在這里顯示。可以改變的需要和應用基礎的基本組成部分。應用 閃蒸干燥可以考慮在幾乎任何應用程序可以被轉換成一個干粉濾餅，離心機蛋糕，污泥或潮濕的固體。 這種技術可以經濟地使用幾乎任何材料范圍從熱敏感的藥品，如青霉素，磺胺類藥物，可可蛋糕等食品原料，淀粉，纖維素，PVC，金屬硬脂酸鹽，礦物質，如碳酸鈣陶瓷，粘土，和許多其他的化學物質，如材料。 此技術是^經濟的，如果只以除去表面水分。FLASH DRYERS KILBURN manufactures Flash Dryers in technical Collaboration with M/S NARA MACHINERY COMPANY, JAPAN, the leading manufacturer of Flash Dryers in the world.This design uses suspended particle drying techniques where surface moisture of the material is rapidly removed by dispersing the particulate solids in a heated stream of gas / air.PRINCIPLE OF OPERATIONThe very word FLASH means instantaneous or rapid drying of products.There are five primary factors which govern the speed of drying. These are :1. MOISTURE DISPERSION This is defined as the accessibility of the moist surface to the drying medium (Hot air or gas). This is achieved in a flash dryer by use of a product disperser such as mechanical scatterer, double paddle feeder or cage mill etc. by mixing dried product in the feed.2. TEMPERATURE DIFFERENTIAL In flash drying it is possible to use high initial temperatures. These are possible due to short contact time with the result that the product temperature never exceeds the wet bulb temperature of the gas unless all surface moisture is removed.3. AGITATION In Flash Dryer, agitation or turbulence is accomplished by the use of high gas velocities. The vapour film is continuously swept away from moist particles. As a result, moisture removal is practically instantaneous.4. PARTICLE STRUCTURE Materials having capillaries will be able to evolve moisture to the surface from internal areas more rapidly resulting in swift drying action. Dense particles which have no voids are difficult to dry in a flash drying system.5. PARTICLE SIZE Drying is accomplished by evaporation from the surface of the particle. Therefore to remove the internal moisture, it is necessary that the moisture reaches the surface by diffusion. This transfer will obviously take place most rapidly with smaller particles.TYPICAL ARRANGEMENTS Several arrangements are possible for individual application to suit specification. A few arrangements are shown here. The basic components can be changed on need & application basis.APPLICATIONS Flash drying can be considered in almost any application where a Filter Cake, Centrifuge Cake, Sludge or Damp solids can be converted to a dry powder. This technique can be economically utilized on practically any material ranging from heat sensitive Pharmaceuticals like sulfa drugs, Penicillin, Food Materials like Cocoa Cake, Starch, Chemicals like Cellulose, PVC, Metallic Stearates, Minerals and Ceramics like Calcium Carbonates, Clay, and many other materials . This technique is most economical if only surface moisture is to be removed.
