一、工作原理及應用范圍介紹 Introduction of Working Principle and Scope of Application
濕物料自加料器連續地加到干燥器上部層干燥盤上，帶有耙葉的耙臂作回轉運動使耙葉連續地翻抄物料。物料沿螺旋線流過干燥盤表面進行傳熱傳質，在小干燥盤上的物料被移送到外緣，并在外緣落到下方的大干燥盤外緣，在大干盤上物料向里移動并從中間落料口落如下一層小干燥盤內緣。大小干燥盤上下交替排列，物料得以連續地流過整個干燥器。中空的干燥盤內通入加熱介質，加熱介質可以是蒸汽、熱水、導熱油和高溫熔鹽等，加熱介質由干燥盤的一端進入，從另一端導出。已干物料從層干燥盤落到殼體的底層，最后被耙葉移送到出料口排出。濕份從物料中溢出，由設在頂蓋上的排濕口排出（真空型盤式干燥器的濕氣由設在頂蓋上的真空泵口排出）。
盤式干燥機是立式連續的以熱傳導為主的干燥設備。廣泛應用于化工、染料、農藥、塑料、醫藥及食品等領域，于干燥技術中有其廣闊的發展前景。如下行業產品：
1. 有機化工
2. 無機化工
3. 醫藥、食品
4. 飼料、 肥料
Wet materials self-charger continuously charges materials to the first layer of drying tray on the top of the drier, and the rabble arm with shovel blade conducts a rotary motion to make the rabble arm shovel the materials continuously. The materials flow through the surface of drying tray along the specified spiral line to conduct heat and mass transfer, and the materials on the small drying tray are transferred to its outer edge and fall on the outer edge of the large drying tray, the materials on the large drying tray move inward and fall on the inner edge of next layer of small drying tray from the middle blanking mouth. Large and small drying trays are arranged up and down alternately, so that the materials can continuously flow through the whole drier. The hollow drying tray is added with heating media such as steam, hot water, conduction oil and high-temperature molten salt. The heating medium enters from one end of drying tray and derived from the other end. The materials which have been dried fall on the bottom layer of shell from the last layer of drying tray, and finally moved to the outlet by shovel blade for discharging. The moisture overflows from the materials and discharged from the moisture discharge outlet on the head cover (the moisture of vacuum type tray drier is discharged from the vacuum pump outlet on the head cover).
Tray drier is a continuous vertical and heat conduction-oriented drying unit, which is widely used in the fields such as chemical industry, dye, pesticide, plastics, medicine and food. Drying technology has its wide development prospects. It can be used for drying the following products:
1. Organic chemical industry
2.Inorganic chemical industry
3.Medicine and food
4. Feed and fertilizer
二、特點Characteristics
1.連續運行，熱效率高。盤式連續干燥機以傳導傳熱方式進行干燥，干燥過程中干燥器內只通入極少量（或不通入）空氣，其尾氣攜帶量很少，故其熱效率可達65%以上。
2.動力消耗低、噪音小。由于干燥過程中料層很薄，主軸轉速低，物料傳送系統所需的功率小，電耗很少，其全套干燥裝置動力消耗僅是對流方式傳熱裝置動力消耗的1/5~1/7，且噪音很小。
3.物料受熱均勻，干燥時間短。由于干燥過程中物料在干燥盤中沿阿基米德螺旋線運動軌跡翻滾前進，物料所走路程為干燥盤半徑的5倍，且逐層下落，因此物料接觸加熱盤面時間基本相同，受熱很均勻。
4.物料損失小、環境保護好。
5.設備密閉連續操作，工人勞動強度低。
1.Continuous operation and high thermal efficiency. Continuous tray drying machine conducts drying by the means of conduction heat transfer. In the process of drying, the drier is injected with a small amount of air (or with no air), it has very little end gas carrying volume, thus its thermal efficiency can reach over 65%.
2.Low power consumption and small noise. Due to very thin bed of materials, low spindle speed, less power required for materials transfer system and less power consumption in the process of drying, the power consumption of the full set of drying unit is 1/5~1/7 of that of convective heat transfer unit and it has very small noise.
3.Materials evenly heated and short drying time. In the processing of drying, the materials roll forward in the drying tray along the Archimedes spiral motion curve and the journey passed by the materials is 5 times of radius of the drying tray, and then the materials fall layer by layer, therefore, the time that the materials contact with the heating plate surface is basically identical and the materials are heated very evenly.
4.Small material loss and good environmental protection.
5.Closed continuous operation of equipment and low labor intensity of worker.
