散料干燥系统是指采用性能卓越的散料搅拌机和散料烘干机，在几秒钟内实现物料的均匀搅拌。机械流态化操作确保所有的粒子都是由干燥介质包围（冷/暖/热空气，惰性气体等）和能量的有效输送，使得水分得以提取从而实现散料干燥的一种系统。

可干燥的散料包括：粉末，散装材料，滤饼状物，微颗粒和液体。

凯睿达散料干燥系统,构建于卓越组件和高端技术，布局合理，工艺可靠，由散料混和器，加热器（电，蒸汽或燃烧），冷却器（冷凝和空气冷却），热交换器，离心式风机和2步过滤系统组成。主过滤器进行连续清理，次过滤器收集细小颗粒，同时采用热泵来提升总热效率。散料干燥系统对产品实行温和干燥，以实现干燥的最佳经济效益。 加热的空气吹入搅拌机和跟湿润的散料混合。在这热交换过程中，水分会从散料中蒸发出来。潮湿的空气在卷入风扇之前，先通过过滤器。之后空气通过冷却器 进行冷凝，然后再加热。干燥非常湿润的产品时，通过先首先混入干燥的产品以保证流化和维持干燥速率。 散料干燥系统可以是封闭也可以是开放的系统。该系统通常配备着一批烘干机，多批次的进行干燥。对于特殊应用，烘干机可以连续工作，散料从气旋或过滤系统产生的排气中分离。

Product: Drying and Dehumidifying System
Product category: Material Processing System

Product introduction:

Drying anddehumidifying system 
    The KRD dryer is a modification of the well-known KRDBulk mixer, wher homogeneous mixing is achieved in a few seconds. Themechanical fluidization ensures that all particles are surrounded by dryingmedium (cold/warm/hot air, inert gas etc.) and an effective transmission ofenergy occurs. Moisture is thereby extracted from the product.

Drying materials: powders, bulk Materials, filter cakes, Granules and liquids 

    The KRD drying technology is built on the well-knowncomponents and principles, which ensure a well arranged and reliable process.It consists of a modified KRD mixer, a heater (electric, steam or combustion),a cooler (for condensation and cooling of air), a heat exchanger, a centrifugalfan and a 2-step filter system. The primary filter for continuous cleaning ,and the secondary filter for collection of fine particles. Heat pump can also beoffered to increase the total thermal efficiency. The KRD Bulk Drying systemhas been especially developed to dry products very gently and to achieve thebest possible drying economy.

     Heated air is blown into the mixer and mixed withmoist product. During this heat exchange, the moisture will evaporate from theproduct. Moist air passes through the filter before it is drawn into the fan.The air is thereafter blown through the cooler for condensation before it isreheated. When drying very moist products, the wet product is mixed with dryproducts first to ensure that the fluidization and the high drying rate aremaintained.

     Today KRD offers the drying system as a closed or opensystem. The system usually operates with a batch dryer, producing multiplebatches. For special applications the dryer can operate continuously wherproduct is separated from the exhaust air in a cyclone or a filtersystem. 

Homogeneous drying: No local overheating, No local over drying, Gentle drying, Low drying temperaturepossible, Good correlation between product temperature and exhaust temperature.The integrated mixing technology always ensures a homogeneous batch

Capacity: High thermal capacity, Can operate close to the products maximum temperature,increasing the drying efficiency, Constant and controlled air supply, No changeof fresh air, Increased total thermal efficiency with the optional use of aheat pump, Batch or continuous drying, Possible drying to absolute dryness.

Inert gas drying: For special applications KRD offers the drying system with inert gas as adrying medium.

Advantages: Prevents oxidation of the product, Drying of solvent based products, Reducesthe possibility of explosion, Closed loop reduces inert gas consumption

Closed loop: No odor to the environment, Constant drying conditions, No effluent gases ordust, Condensation of water vapor, Energy saving due to recuperation of heat.
Inert gas drying as an option, Open system as an option

Control system: Customized control system, Temperature monitoring, together with homogenymixture avoids variations, Easy definition of stop parameters for batchprocess, Overfilling and over drying are automatically avoided, Filter cleaningand monitoring give no effluent dust, Automatic operation possible
