■ 原理 principle
◎ 濕物料自加料器連續(xù)地加到干燥器上部*層干燥盤(pán)上，帶有耙葉 的耙臂作回轉(zhuǎn)運(yùn)動(dòng)使耙臂作回轉(zhuǎn)運(yùn)動(dòng)使耙葉連續(xù)地翻抄物料。物料沿 指數(shù)螺旋線流過(guò)干燥盤(pán)表面，在小干燥盤(pán)上的物料被移送到外緣，并 在外緣落到下方的大干燥盤(pán)外緣，在大干盤(pán)上物料向里移動(dòng)并從中間 落料口落入下一層小干燥盤(pán)中。大小干燥盤(pán)上下交替排列，物料得以 連續(xù)地流過(guò)整個(gè)干燥器。中空的干燥盤(pán)內(nèi)通入加熱介質(zhì)，加熱介質(zhì)形 式有飽和蒸汽、熱水和導(dǎo)熱油，加熱介質(zhì)由干燥盤(pán)的一端進(jìn)入，從另 一端導(dǎo)出。已干物料從zui后一層干燥盤(pán)落到殼體的底層，zui后被耙葉 移送到出料口排出。濕份從物料中逸出，由設(shè)在頂蓋上的排濕口排 出，真空型盤(pán)式干燥器的濕氣由設(shè)在頂蓋上的真空泵口抽出。從底層 排出的干物料可直接包裝。通過(guò)配備翅片加熱器、溶劑回收冷凝器、 布袋除塵器、干料返混機(jī)構(gòu)、引風(fēng)機(jī)等輔機(jī)，可提高其干燥的生產(chǎn)能 力，干燥膏糊狀和熱敏性物料，可方便地回收溶劑，并能進(jìn)行熱解和 反應(yīng)操作。
◎ Wet materials are fed continuously to the top drying layer in the drier. they will be turned and stirred continuously by harrows when the harrowÕs arm rotates, the material flows through the surface of the drying plate along the exponential helical line. On the small drying plate the material will be moved to its exterior edge and drop down to the exterior edge of the large drying plate underneath, and will then be moved inward and drop down from its central hole to the small drying plate on the next layer. Both small and large drying plates are arranged alternay so as materials can go through the whole drier continuously. the heating media, which could be saturated steam, hot water or thermal oil will be led into drying plates from one end to other end of the drier. the dried product will drop from the last layer of the drying plate to the bottom layer of the body, and will be moved by harrows to the discharge outlet. the moisture exhausts from materials and will be removed from the moist discharge outlet on the top cover, or sucked out by the vacuum pump on the top cover for vacuum-type plate drier. the dried product discharged from the bottom layer can be packed directly. the drying capability can be raised up if equipped with supplementary devices such as finned heater, condenser for solvent recovery, bag dust filter, return and mix mechanism for dried materials and suction fan etc. solvent in those paste state and heat sensitive materials can be easily recovered, and thermal decomposition and reaction can be also carried out.

■ 特點(diǎn) FeAtUres
◎ 調(diào)控容易、適用性強(qiáng)
1、通過(guò)調(diào)整料層厚度、主軸轉(zhuǎn)速、耙臂數(shù)量、耙葉型式和尺寸可使干 燥過(guò)程達(dá)到*。
2、每層干燥盤(pán)皆可單獨(dú)通入熱介質(zhì)或冷介質(zhì),對(duì)物料進(jìn)行加熱或冷卻,物 料溫度控制準(zhǔn)確、容易。 3、物料的停留時(shí)間可以精確調(diào)整。
4、物料流向單一，無(wú)返混現(xiàn)象，干燥均勻、質(zhì)量穩(wěn)定、不需再混合。
◎ 操作簡(jiǎn)單、容易
1、干燥器的開(kāi)車(chē)、停車(chē)操作非常簡(jiǎn)單。
2、停止進(jìn)料后，傳送物料后耙葉能很快地排空干燥器內(nèi)的物料。
3、通過(guò)特殊的大規(guī)格檢視門(mén)的視鏡，可以對(duì)設(shè)備內(nèi)進(jìn)行很仔細(xì)的清洗 和觀察。
◎ 能耗低
1、 以傳導(dǎo)熱進(jìn)行干燥，熱效率高，能量消耗低。
◎ 操作環(huán)境好，可回收溶劑，粉塵排放符合要求
1、 常壓型：由于設(shè)備內(nèi)氣流速度低,而且設(shè)備內(nèi)濕度分布上高下低,粉塵很 難浮到設(shè)備頂部,所以頂部排濕口排出的尾氣中幾乎不含有粉塵。
2、密閉型：配溶劑回收裝置,可方便地回收載濕氣體中的有機(jī)溶劑。溶劑 回收裝置簡(jiǎn)單，回收率高，對(duì)于易燃、易爆、有毒和易氧化的物 料，可用氮?dú)庾鳛檩d濕氣體進(jìn)行閉路循環(huán)，使之安全操作。特別適 用于易燃、易爆、有毒物料的干燥。
3、真空型：在真空狀態(tài)下操作的盤(pán)式干燥器，特別適用于熱敏性物料 的干燥。
◎ 安裝方便、占地面積小
1、干燥器整體出廠，整體運(yùn)輸，只需吊裝就位，安裝定位非常容易。
2、由于干燥盤(pán)層式布置、立式安裝，既使干燥面積很大,占地面積也很小。
