1.Descriptions
PLG Series Continual Plate Dryer Descriptions Plate dryer is a kind of high effective conducting and continuous drying equipment . Its unique structure and operating principle determine that it has advantages of high heat efficiency, low energy consumption,small occupying area,simple configuration,easy operating and control as well as friendly operating environment etc . It can be widely used in drying process in the fields of chemical industry. Pharmaceuticals , agricultural che micals , foods tuff , fodder , process of agricultural and sideline products etc , and is well received by various sectors in their practical usage . Now there are three big categorie s, named normal pressure , closed and vacuum styles; four sizes of 1200,1500,2200 and 3000; and three kinds of materials, namely A(carbon steel), B(stainless steel used for those all parts where materials are contacted) and C ( on the basis of B to add stainless steel materials for vapor pipes, main shaft and support, and stain -less steel linings for cylinder body and top cover). With a drying area being from 4 to 180 square metres, now we have hundreds of models of series products and various kinds of auxiliary devices available to meet requirements of drying materials for customers.
二、原理
湿物料自加料器连续地加到干燥器上部较好层 干燥盘上 ，带有耙叶的耙臂作回转运动使耙叶连续地翻抄物料 。物料沿指数螺旋线流过干燥盘表面 ，在小干燥盘上的物料被移送到外缘 ，并在 外缘落到下方的大干燥盘外缘，在大干燥盘上物料向里移动并从中间落料口落入下一层小干燥盘中 。大小干燥盘上下交替排列 ，物料得以连续 地流过整个干燥器。中空的干燥盘内通入加热介质 ，加热介质形式有饱和蒸汽 、热水和导热油 ，加热介质由干燥盘的一端进入，从另一端导出 。已干物料从较后一层干燥盘落到壳体的底层 ，较后被耙叶移送到出料口排出 。湿份从物料中逸出 ，由设在顶盖上的排湿口排出，真空型盘式 干燥器的湿气由设在顶盖上的真空泵口抽出 。从底层排出的干物料可直接包装 。通过配加翅片加热器 、溶剂回收冷凝器、袋式除尘器、干料返 混机构、引风机等辅机，可提高其干燥的生产能力，干燥膏糊状和热敏性物料，可方便地回收溶剂，并能进行热解和反应操作。
2.Principles
Wet materials are fed continuously to the first dryinglayer on the top of the dryer .They will be turned and stirred by rakes when the rake arm rotates and drop down to the outer edge of the large drying plate along the exponential helical line.On the small drying plate they will be moved to its outer edge and drop down to the outer edge of the large drying plate underneath,and will 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 alternately so as materials can go through the whole dryer continuously.The heating media,Which could be informs of saturated steam,hot water or heat conducting oil will be led into hollow drying plates from one end to the other end of the dryer.The dried materials will drop from the last layer of the drying plate to the bottom layer of the shell body,and will be moved by rakes to the dischargeport.The moisture escapes from materials and will be removed from the moist discharge port on the top cover,or sucked out by the vacuum pump one the top cover for vacuum-type plate dryer.The dried materials 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 in those dried paste and heat sensitive materials can be easily retrieved,and thermal decomosition and reaction can be also carried out.
