以前的博客文章中提到的，Rotacurrent和Venturijet的闪蒸干燥机利用选择性的原则运作，每个人都有自己独特的优势。处理的非粘性Rotacurrent产品没有返混，中而Venturijet会降低旋流器的大小和互补集尘设备。 Heyl帕特森提供两种类型，但本文将重点对Rotacurrent。的Rotacurrent闪蒸干燥机中的停留时间变化，根据其物理性质，对每个粒子，每个粒子的停留时间，它的重量成比例。这将导致在没有过度干燥，无过热和处理任何不必要的风险或产品降解。在闪蒸干燥机的Rotacurrent，制造Heyl＆Patterson的Renneburg分部，每个粒子需要其自己的螺旋路径的干燥塔的顶部。路径的总长度，构成为颗粒的总的停留时间。由于螺旋轨迹，停留时间是干燥器的实际柱高度无关。细颗粒具有短的停留时间，而较重的有较长的时间。特强，不良份子分离和消除在干燥器的列的基础上通过检查放电陷阱。湿进料进入的Rotacurrent的的机通过在干燥塔的基础上的气闸。通过常规的热源，它被注入到主热空气流。然后将湿的饲料如下螺旋路径通过干燥塔内部。在蒸馏柱底部的排出门是反加权，所以额外的重粒子如肿块，宝石和杂散金属被自动排出。这的陷阱也允许目视检查和物理访问的列的内部。有在柱顶部的另一检查门。在一些模型中，热的，干燥的空气的二次供应被添加到主流程通过可调节百叶窗沿气缸的内部隔开。该二次空气流产生一个机械的效果，补强的初始螺旋空气流，和热效应的主空气流拿起水分和在蒸发过程中冷却，以补偿损失的干燥潜力经加工的产品在通过出口涡旋盘，并进入一个额外的高效率的旋流器的列的顶部排出。这旋风实现非常有效的分离，节约资金和能源。在产品离开旋流器通过气闸和定向到储存或立即使用的导管。烘干机排出废气由一个风扇，并可以部分地用于热回收再循环。湍流传热和彻底的颗粒分散结合内的Rotacurrent的闪存机为^高热效率。列设计的外部的热辐射的损失^小化。由于良好的热传导性能，柱的高度，其他尺寸小于同等大小的，传统的烘干机。其结果是，建设成本和绝缘要求也较低。由于气流移动的产品，而不是机械的手段，Rotacurrent^少的移动部件。 Rotacurrent机的日常维护活动也提高了运营商的流动和连续的视觉检查，通过直接访问柱内饰。为了提高加工效率，先前干燥的产品的一部分，可以被重新引入糊状粘性产品的主要流。混纺或“返混”的原料通常可以更加简单且有效地进行处理。此外，一个特别设计的研磨和干燥的系统可以被提供，和溶剂浸渍的产品可以在惰性气体的处理，以实现溶剂回收。所有Rotacurrent闪蒸干燥器和冷却器可提供与控制柜容纳自动化控制及仪器仪表。一个Rotacurrent闪蒸干燥机是几台机器，可在Heyl和帕特森的研究实验室之一，任何产品的完整的测试，以确保客户加工各种规格。As mentioned in a previous blog article, the Rotacurrent and Venturijet Flash Dryers operate utilizing the selective principle, and each has its own particular advantages. The Rotacurrent handles non-sticky products without back-mixing, while the Venturijet reduces the size of the cyclone and complementary dust collection equipment. Heyl & Patterson offers both types, but this article will focus on the Rotacurrent.Residence time in the Rotacurrent Flash Dryer varies for each particle according to its physical properties, as each particle has a residence time proportionate to its weight. This results in no overdrying, no overheating and no unnecessary processing risks or product degradation.In the Rotacurrent Flash Dryer, manufactured by Heyl & Patterson's Renneburg Division, each particle takes its own spiral path to the top of the drying column. The total length of the path constitutes the total residence time for the particle. Because of the spiral trajectory, residence time is independent of the dryer's actual column height. Fine particles have short residence times, while heavier ones have longer times. Extra-heavy, undesirable elements are separated and eliminated via the inspection-discharge trap at the base of the column of the dryer.Wet feed enters the Rotacurrent dryer through an airlock at the base of the drying column. It is injected into the main hot air stream by a conventional heat source. The wet feed then follows a spiral path up through the interior of the drying column.The discharge gate at the bottom of the column is counter-weighted so extra-heavy particles such as lumps, stones and stray metal are automatically discharged. This trap also permits visual inspection and physical access to the interior of the column. There is another inspection door at the top of the column.In some models, a secondary supply of hot, dry air is added to the main flow through adjustable louvers spaced along the inside of the cylinder. This secondary air stream produces a mechanical effect to reinforce the initial spiral air flow, and a thermal effect to compensate for the loss of drying potential as the main air flow picks up moisture and cools during the evaporation processThe processed product exits at the top of the column through the outlet scroll and into an extra high-efficiency cyclone. This cyclone accomplishes very effective separation, saving money and energy. The product leaves the cyclone through an airlock and a duct directed to storage or immediate use. Dryer exhaust is discharged by a fan and can be partially recycled for heat recovery.Turbulent heat transfer and thorough particle dispersion combine inside the Rotacurrent Flash Dryer for maximum thermal efficiency. The design of the column minimizes the loss of external heat radiation. Due to excellent heat transfer performance, column height and other dimensions are smaller than comparably sized, conventional dryers. As a result, building costs and insulation requirements are also lower.Because airflow moves the product rather than mechanical means, the Rotacurrent has minimal moving parts. Rotacurrent dryer routine maintenance activities are also enhanced by the operator's continuous visual inspection of the flow and by direct access to column interiors.To improve processing efficiency, a portion of previously dried product can be re-introduced into the primary stream of pasty of sticky product. The blended or "back-mixed" feed stock can generally be processed much more simply and effectively. In addition, a specially designed grinding and drying system can be supplied, and solvent-impregnated products may be processed in inert gases to achieve solvent recovery. All Rotacurrent Flash Dryers and Coolers can be supplied with control cubicles to house automatic controls and instrumentation.A Rotacurrent Flash Dryer is one of several machines available at Heyl & Patterson's research laboratory, to assure the complete testing of any product to a customer's processing specifications. 1．粉碎机必须固定安装，而粉碎机皮带轮与动力机皮带轮的轴线应平行，两传动皮带轮槽必须在同一条直线上，否则，不但加速机件的损坏，而且容易掉皮带。
