关头词:美国torusdisc单双翼扭转枯燥体系

torusdisc® - 单或双旋翼机

torusdisc®机/加热器/冷却器是一种直接式换热器,与机器搅拌的资料。这类直接加热和枯燥体系供给间歇或持续的直接加热,枯燥,冷却或反映的固体,泥浆,凝胶,滤饼,粉剂,和粘性资料。

torusdisc®处置器由一个牢固的程度与垂直装配的双层盘管式转子容器。这些光盘,供给约85%的总的加热外表。其余的加热外表是转子轴和夹套容器槽的内壁上。

在操纵进程中的这类直接加热和枯燥体系,高的绝对速率之间的扭转盘和产物有助于高传热系数。搅拌的犁或刮板栏能够被增添到增添新的外表打仗,避免物料聚积在外表上。这些设想特色许可的torusdisc®完成热传输系数大于良多其余的直接枯燥机的二至六倍。其转子速率能够被设置为^佳的热互换和完全夹杂,逗留时候有关。的逗留时候规模从几分钟到几个小时,使几近比其余任何直接热互换器现今更通用的torusdisc®。

torusdisc直接枯燥机的特色, 1。小空间的请求 2。高效节能 3。^大的枯燥效力 4。传热系数高 5。产物的多功效性 6。利用特色 7。蒸汽需要削减 8。保护本钱低

直接驱动的torusdisc的利用

食物 酿酒厂和啤酒厂废旧产物 正己烷提取豆粕 大豆卵白葡萄糖 玉米和大豆华侈产物 鱼粉 肉by-products/rendering

化学品 氧化物 氢氧化物 无机盐 邃密化学品 制药

矿物 煤 石灰 水泥 黄饼 颜料

石化/塑料 abs 己二酸 丙烯酸树脂 醋酸盐 聚碳酸酯 聚丙烯 聚乙烯 对苯二甲酸

体系#1

传热流体流经装配在转子上的筒状的转子和中空光盘。流体也流经转子四周的外衣。

牢固搅拌器犁或刮刀酒吧位于盘之间的,以到达更好的夹杂和传热外表上,以避免资料储蓄积累。运输的产物是经由进程在轴向标的目的上朝向排挤真个光盘和容器之间的环形空间,影响高夹套的传热率。可调的保送叶片的外边缘牢固到光盘节制搬送。

逗留时候是自力的转子速率是可调的装配的排挤端位于溢流堰。是以,该单元能够在^佳的热通报的^佳转子速率操纵。

的筒状转子能够分为两个局部慢慢加热和冷却进程中,利用差别的具备差别温度的热通报介质。

作为机本机具备两种任务形式: 1。直接传热 2。直接和直接枯燥体系

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

applications of the torusdisc indirect driver

food distillery and brewery waste products hexane extracted soybean meal soy protein dextrose corn and soybean waster products fish meal meat by-products/rendering processes

chemicals oxides hydroxides inorganic salts fine chemicals pharmaceuticals

minerals coal lime cement yellow cake pigments

petrochemicals / plastics abs adipic acid acrylics acetates polycarbonate polypropylene polyethylene terephthalic acid

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
