YP 系列盘式连续干燥机
(一)干燥盘
采用夹层式换热,可由蒸汽、热水、导热油加 热,一般夹层压力≤0.4MPa,高压可以订做。
(二)物料传送系统
1. 主轴转速:1-10转/分, 电磁或变频无级调速。
2. 耙臂:每层干燥盘上有2-8支固定在主轴上的耙 臂。
3. 耙叶:绞接在耙臂上, 能随盘面上下浮动保持接 触, 有多种形式。
4. 碾滚:对易结块和需要破碎的物料,在适当位 置配加碾滚,可以强化传热和干燥过程。
(三)壳体 有常压、密闭、真空三种型式
1. 常压型:圆筒或八棱柱形,有整体和对开两种 结构。加热介质进出口主管道可以在壳体内,也可 以在壳体外。
2. 密闭型:圆筒形壳体,能承受5Kpa内压,加热 介质进出口主管道可以在壳体内,也可以在壳体 外。
3. 真空型:圆筒形壳体,设计压力为外压0.1MPa, 加热介质进出口主管道在壳体内。
(四)空气加热器 一般在蒸发量较大的情况下使用, 以增强干燥效 率。YP 系列盘式连续干燥机
1. Drying plate
(1) Desiging pressure: general is 0.4MPa, Max. can reach 1.6MPa.
(2) Work pressure: general is less than 0.4MPa, and max. can reach 1.6MPa.
(3) Heating medium:steam, hot water,heat transfer oil. When the drying plates’ temperature is 100℃, hot water can be used ; when 100℃~150℃,it will be satu- rated water steam ≤0.4MPa or steam-gas, an when 150℃~320℃,it will be heat transfer oil; when >320℃ it will be heated by electric, oil or fused salt.
2. Material transmission system
(1) Main shaft revoluton: 1~10rpm, electromagnetism or stepless speed regulation by inverter.
(2) harrow arm: There are 2 to 8 pieces arm that be fixed on the headstock on the every layers.
(3) Harrow’s blade: Surrounding the harrow’s blade, float together with the surface of the plate to keep contact. There’re various of types.
(4) Roller: for the products easily agglomerate, or with the requirements of grinding, the heat transfer and drying process might be reinforced by placing roller(s) at the appropriate place(s).
3.Shell
There’re three types for option: normal pressure, sealed and vacuum
(1) Normal pressure:
(2) Sealed: Cylindrical shell, could bear the interior pressure of 5KPa, the main ducts of the inlet and outlet of heating media might be inside of the shell or outside.
(3) Vacuum: Cylindrical shell, could bear the exterior pressure of 0.1MPa. The main ducts of inlet and outlet is inside of the shell.
4. Air heater
Normal for the application of big evaporation capacity to increase drying efficiency.
