連續傳導干燥機-金陵干燥

比較連續傳導干燥機

傳導干燥的方式來處理熱敏感材料，控制干燥過程中的氣氛，以確保^終產品的質量，或使用的廢熱源干燥，以減少能源成本。上周的文章討論分類的干燥方法，傳導干燥機是如何工作的，看著一批傳導機的類型。這篇文章比較連續導通機的類型。

一種連續傳導干燥器可以干熱敏感的溶液，淤漿，糊劑和顆粒劑含有顏料，石膏，粘土，精細化學品，粉煤和它的鹽，可用于相對較短的滯留時間。干燥器輸送以及干燥的材料;控制的傳送速度控制的保留時間。連續傳導干燥器不需要材料處理勞動，使得其操作成本通常遠低于一個批處理單元。

某些功能有所不同機類型，包括如何有效地連續干燥機可以傳達以及您的材料和相關設備需要養活干燥和接收的材料和處理烘干機的廢氣。單元通常工作在大氣和輕微的負壓力。燃料需求的范圍從1.0至2.0磅的每磅水蒸汽蒸發，這取決于該材料所需的^終水分含量。一批單位，連續干燥機是在尺寸從實驗室到規模化生產提供。能源成本也取決于材料和你的應用程序需要多少攪拌或疏散。

連續導通機的幾種類型可供選擇：蒸汽管回轉，鼓機，螺旋輸送機，振動盤和間接的多種光盤。

一種蒸汽管回轉干燥機包括一個水平的，圓筒狀的旋轉緊固到容器壁上，通過蒸汽填充管加熱的容器。熱傳輸通過管子的材料，因為它流經容器。的干燥機通常用于干纖維和自由流動的粉末，特別是化學品和低密度粉末如食品。

甲滾筒式干燥器典型地具有一個或兩個水平，加熱夾套的旋轉滾筒。該鼓筒旋轉不僅有利于傳熱從血管壁的材料，但也朝向出口的材料移動。在滾筒式干燥器干燥片狀或灰塵多的粉末，以及作為可流動的漿料或廢渣的液體溶液或漿料。因為軸承的旋轉機構必須經常上油，用雙鼓單元，單位可以是昂貴的維護，鼓必須保持對齊，以確保流程的一致性。

甲螺旋輸送機機通常包括一個或多個旋轉螺釘水平，圓柱形熱夾套容器內。加熱介質是蒸汽或熱水。每個螺釘也可以被加熱。隨著螺桿軸的旋轉時，在血管壁和螺桿航班熱傳導的材料，并將其推通過干燥器。的干衣機可以干燥的非粘性，低水分含量的顆粒，晶體，纖維和自由流動的粉末，它可以恢復一些溶劑。該裝置可以作為一個輔助的干燥器，以除去水分，從購買的材料，將在非常高的溫度下進行熱處理。這種預干燥是比除去水分的過程中的熱處理過程中更有效率。盡管干燥器的連續模式下，它也可以在真空下進行操作。

振動托盤干燥器由一個矩形的加熱夾套的容器中的一個或多個加熱的金屬托盤。該托盤的材料振動，并移動它朝向干燥器出口或下一個托盤。的干衣機可以處理的自由流動的粉末，以及顆粒劑，晶體和纖維，可以通過振動輸送。干燥器是機械比一個螺旋輸送器干燥器更穩定，因此它可以在較高的溫度下的應用，如用作催化劑的陶瓷和粘土干燥。

一種間接的多個圓盤式干燥機，如Heyl＆Patterson的MultiDisc熱的處理器，包括一個水平的槽狀容器，含有兩個或兩個以上的旋轉軸安裝有光盤。大表面面積的碟片被加熱。作為軸旋轉，圓盤接觸并同時輕輕拖動，而不是將其推至容器內，將熱量傳遞給該材料。的干衣機可以處理泥漿，淤泥，糊劑，自由流動的粉末，顆粒劑，晶體和纖維。光盤還打破了腫塊，使本機適用于處理土壤，擠出物和其他塊狀材料。軸的速度和光盤溫度可以改變，而不影響材料的保留時間。干燥在低溫下是有效的，因為在軸速度和盤的溫度，可以改變從模塊到模塊。

Comparing Continuous Conduction Dryers

Conduction drying is one way to handle heat-sensitive material, control a drying process atmosphere to ensure final product quality, or use a waste-heat source to cut energy drying costs.  Last week's post discussed classifying drying methods, how a conduction dryer works and looked at the types of batch conduction dryers.  This post compares the types of continuous conduction dryers.

A continuous conduction dryer can dry heat-sensitive solutions, slurries, pastes and granules containing pigments, gypsum, clays, fine chemicals, fine coal and salts, and can be used for relatively short retention times.  The dryer conveys as well as dries the material; controlling the conveying speed controls the retention time.  The continuous conduction dryer requires no material-handling labor, making its operating cost typically much lower than that of a batch unit.

Some features vary by dryer type, including how efficiently the continuous dryer can convey as well as dry your material and what related equipment is needed to feed and receive the material and handle the dryer's exhaust gas.  The unit typically operates at atmospheric and slightly negative pressures.  Fuel requirements range from 1.0 to 2.0 pounds of steam per pound of water evaporated, depending on the material's required final moisture content.  As with a batch unit, the continuous dryer is available in sizes from lab- to full-scale production.  Its energy costs also depend on the material and how much agitation or evacuation your application requires.

Several types of continuous conduction dryers are available:  steam-tube rotary, drum, screw conveyor, vibrating tray and indirect multiple disc.

A steam-tube rotary dryer consists of a horizontal, cylindrical rotating vessel heated by steam-filled tubes fastened to the vessel wall.  Heat transfers through the tubes to the material as it flows through the vessel.  The dryer is typically used to dry fibers and free-flowing powders, particularly chemicals and low-density powders such as foodstuffs.

A drum dryer typically has one or two horizontal, heat-jacketed rotating drums.  The drum rotation not only facilitates heat transfer from the vessel wall to the material but also moves the material toward the outlet.  The drum dryer can dry liquid solutions or slurries to flakes or dusty powders, as well as flowable pastes or sludges.  The unit can be expensive to maintain because the bearings for the rotating mechanism must be oiled frequently and, with a two-drum unit, the drums must be kept in alignment to ensure process consistency.

A screw conveyor dryer typically consists of one or more rotating screws inside a horizontal,  cylindrical heat-jacketed vessel.  The heating media is steam or hot water.  Each screw can also be heated.  As the screw shaft rotates, the vessel wall and screw flights conduct heat to the material and push it through the dryer.  The dryer can dry non-sticky, low-moisture-content granules, crystals, fibers and free-flowing powders, and it can recover some solvents.  The unit can be used as an auxiliary dryer to remove moisture from a material that will later be heat-treated at very high temperatures.  Such predrying is more efficient than removing moisture during the heat-treating process.  Despite the dryer's continuous mode, it can also be operated under vacuum.

A vibrating tray dryer consists of a rectangular heat-jacketed vessel containing one or more heated metal trays.  The tray vibrates the material and moves it toward either the dryer outlet or the next tray.  The dryer can handle free-flowing powders as well as granules, crystals and fibers that can be conveyed via vibration.  The dryer is mechanically more stable than a screw conveyor dryer, so it can dry at higher temperatures for applications such as ceramics and clays used as catalysts.

An indirect multiple disc dryer, such as Heyl & Patterson's MultiDisc Thermal Processor, consists of a horizontal trough-shaped vessel, containing two or more rotating shafts mounted with discs.  The large-surface-area discs are heated.  As the shafts rotate, the discs contact and transfer heat to the material while gently dragging rather than pushing it through the vessel.  The dryer can handle slurries, sludges, pastes, free-flowing powders, granules, crystals and fibers.  The discs also break up lumps, making the dryer suitable for handling soil, extrudates and other lumpy materials.  The shaft speed and disc temperature can be varied without affecting the material's retention time.  Drying is efficient at low temperatures because the shaft speed and disc temperature can vary from module to module.

Heyl & Patterson designs and builds dryers to provide years of trouble-free operation, and offers facilities for laboratory testing.  Because we custom engineer each MultiDisc Thermal Processor and maintain the original drawings, we can service your dryer according to its original specifications. We oversee delivery, installation and start-up of your equipment, and provide preliminary operating instructions to your personnel.

We also provide manufacturer-direct parts that meet original equipment specifications, ensuring that any upgrades or repairs will meet or exceed the original equipment's performance levels.
