Dedert's new range of spray dryers, built around the innovative, patent pending atomizer, adds to its expansive portfolio of leading evaporation and drying technologies and enhances Dedert's reputation for quality and performance.The new design, based on magnetic bearing technology, eliminates the need for high maintenance gear drives, bearings, shafts, oil lubrication and cooling systems, providing unparalleled flexibility for the most demanding applications. The cutting edge rotary atomizer is a robust mechanical and compact design, which offers lower maintenance and higher reliability over conventional rotary technology. The atomizer is provided complete with variable speed drive and a fully automated PLC-based utility and control system.Key features of the rotary atomizer: • Built around magnetic bearing technology. • Capable of 16,000rpm, designed to run below first critical speed. • High capacity units available up to 350hp. • Immediately compatible with existing installations. • Complete strategic units held in storage in Chicago, IL. • Easy to maintain and service.Spray drying is the process of atomizing a liquid feed in either a slurry or solution form into fine droplets. Heated drying gas then converts the atomized particles into a dry powder by evaporation of the liquid phase. The atomization process can be accomplished with a rotary wheel coupled to a high speed drive or a spray nozzle atomizing system. Both methods offer advantages for specific product properties, including particle size and distribution, density, shape and morphology, and dispersibility.Rotary atomization is the most flexible method of controlling feed rate and dryer operation while maintaining the required dry product specifications. Combined with a specially designed atomizing wheel and liquid feed distributor, the rotary atomizer can accommodate a broad range of liquid feeds, including abrasive products.The new spray dryer is enhanced with an innovative gas disperser to ensure optimum contact between the heated drying gas and atomized spray cloud, and thereby improve dryer performance and efficiency.A proprietary explosion vent door protection system for new and existing installations meets the latest code requirements and is flush mounted, providing a sanitary tight seal design.The spray drying systems are supplied with the most efficient product separation and gas cleaning technology available. High efficiency cyclones, bag filters or wet scrubbers are incorporated for pollution control to meet the most rigid plant emission requirements. Fully integrated thermal oxidation systems can also be included for removal of VOC and other emissions.The spray drying system can be in single or multiple stages with integrated fluid bed processing. The fluid bed system is typically provided for post drying, agglomeration, conditioning and cooling. Dedert’s Spray Drying systems are available from pilot scale up to 20,000 kg/hr evaporation.Energy integration and heat recovery offers the most energy efficient system. Combined with Dedert evaporation systems, Dedert can provide a complete liquid concentration to dry product plant for the food and chemical industries.Dedert is well placed to offer spray dryer replacement, retrofits, upgrades and audits; we offer a complementary review of existing spray drying plants.Dedert spray dryers are used in the food industry for products such as: ingredients, spices, sweeteners, flavors, botanicals, nutraceuticals, vitamins, minerals, emulsions, flavors, proteins, yeast, starches and sugars.For the chemical industry, Dedert spray dryers are used for products such as: specialty chemicals, inorganic chemicals, minerals, pigments and dyestuffs, and ceramics.资讯导读:降低出风温度。当出风温度过高无疑是不利于节能减排的。经过统计我们发现,降低出风温度与提高进风温度两者相比,前者更为经济。而出风温度的调整需要参考物料的含水率。 喷雾干燥机是一种连续式常压干燥器的一种,设备在使用的过程中将其液料喷成雾状,这样就可以使热空气接触而被干燥,主要是资讯导读:物料落入喷雾干燥机中的流化床从室中排出前被干燥,以正确的水分含量。为了优化粒径的控制,夹在花干燥空气产品在旋风分离器或织物过滤被分离出来并返回到在干燥室中的雾化区域。凝聚和粒径的程度是通过操作条件,这改变在雾化区中的颗粒的残余水分含量的影响。可形成大范围的粒径。可溶性和不溶性的产品可以在这喷雾干燥机是一种可以同时完成干燥和造粒的装置。按工艺要求可以调节料液泵的压力、流量、喷孔的大小,得到所需的按一定大小比例的球形颗粒。 喷雾干燥机为连续式常压干燥器的一种。用特殊设备将液料喷成雾状,使其与热空气接触而被干燥。用于干燥有些热敏性的液体、悬浮液和粘滞液体,如牛奶、蛋、单宁和药物等资讯导读:粘壁是影响喷雾干燥机正常运行的问题之一。富含动物脂肪的食品往往会沉积在干燥室的壁上。随着时间的推移,这些食品原料将逐渐成为污染源,并危害食品健康。因此,许多喷雾干燥机制造商已经探索了一些解决粘壁问题的方法。 粘壁是影响喷雾干燥机正常运行的问题之一。富含动物脂肪的食品往往会沉资讯导读:喷雾干燥机的^常见的类型被称为单效应。有在腔室的顶部干燥空气的单个源。在大多数情况下,空气在相同的方向上喷射的液体(顺流)吹出。用微粉生产,但它可以有流动性差,并产生大量的粉尘。为了克服粉尘和粉末的流动性差,新一代的喷雾干燥机的称为多效喷雾干燥机已经产生。 喷雾干燥机的^常
