torusdisc® - 单或双旋翼机

torusdisc®机/加热器/冷却器是一种间接式换热器,与机械搅拌的材料。这种间接加热和干燥系统提供间歇或连续的间接加热,干燥,冷却或反应的固体,泥浆,凝胶,滤饼,粉剂,和粘性材料。

torusdisc®处理器由一个固定的水平与垂直安装的双层盘管式转子容器。这些光盘,提供约85%的总的加热表面。其他的加热表面是转子轴和夹套容器槽的内壁上。

在操作过程中的这种间接加热和干燥系统,高的相对速度之间的旋转盘和产品有助于高传热系数。搅拌的犁或刮板栏可以被添加到增加新的表面接触,防止物料堆积在表面上。这些设计特点允许的torusdisc®实现热传输系数大于很多其他的间接干燥机的二至六倍。其转子速度可以被设置为^佳的热交换和彻底混合,停留时间无关。的停留时间范围从几分钟到几个小时,使几乎比其他任何间接热交换器当今更通用的torusdisc®。

torusdisc间接干燥机的特点, 1。小空间的要求 2。高效节能 3。^大的干燥效率 4。传热系数高 5。产品的多功能性 6。应用特点 7。蒸汽需求减少 8。维护成本低

系统#1

传热流体流经安装在转子上的筒状的转子和中空光盘。流体也流经转子周围的外套。

固定搅拌器犁或刮刀酒吧位于盘之间的,以达到更好的混合和传热表面上,以防止材料积聚。运输的产品是通过在轴向方向上朝向排出端的光盘和容器之间的环形空间,影响高夹套的传热率。可调的输送叶片的外边缘固定到光盘控制搬送。

停留时间是独立的转子速度是可调的装置的排出端位于溢流堰。因此,该单元可以在^佳的热传递的^佳转子速度操作。

的筒状转子可以分为两个部分逐步加热和冷却过程中,使用不同的具有不同温度的热传递介质。

作为机本机具有两种工作模式: 1。间接传热 2。直接和间接干燥系统

torusdisc® - single or twin rotor dryer

the torusdisc® dryer/heater/cooler is an indirect heat exchanger, with mechanical agitation of material. this indirect heating and drying system provides batch or continuous indirect heating, drying, cooling or reaction of solids, slurries, gels, filter cakes, powders, and viscous materials.

the torusdisc® processor consists of a stationary horizontal vessel containing a tubular rotor with vertically mounted double-walled discs. these discs provide approximately 85% of the total heating surface. other heating surfaces are the rotor shaft and the inner wall of the jacketed vessel trough.

during operation of this indirect heating and drying system, a high relative velocity between the rotating discs and the product contributes to a high heat transfer coefficient. agitator plows or scraper bars can be added to increase exposure of new surfaces and prevent material build-up on surfaces. these design features allow the torusdisc® to achieve heat transmission-coefficients two to six times greater than many other indirect dryers. its rotor speed can be set for optimum heat exchange and thorough mixing, independent of residence time. residence time ranges from minutes to several hours, making the torusdisc® more versatile than almost any other indirect heat exchanger available today.

features of the torusdisc indirect dryer 1. small space requirements 2. energy efficient 3. maximum drying efficiency 4. high heat transfer coefficient 5. product versatility 6. application versatility 7. reduced steam requirements 8. low maintenance

system # 1

heat transfer fluid flows through a tubular rotor and hollow discs mounted on the rotor. fluid also flows through the jacket surrounding the rotor.

stationary agitator plows or scraper bars are located between the discs in order to achieve better mixing and to prevent material build-up on heat transfer surfaces. transport of product is in an axial direction through the annular space between the discs and the vessel toward the discharge end, effecting high jacket heat transfer rates. adjustable conveying vanes are fixed to the outer rim of the discs to control conveyance.

residence time is independent of rotor speed and is adjustable by means of an overflow weir located at the discharge end. therefore, the unit can be operated at the best rotor speed for optimum heat transfer.

the tubular rotor can be divided into two sections for gradual heating and cooling processes using different heat transfer media with different temperatures.

this unit as a dryer has two operating modes: 1. indirect heat transfer 2. combination direct and indirect drying system
