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:自吸蠕动泵(自吸)从水箱通过小直径的喷嘴提供流体样品进入主室(主室)。在同一时间进入它在液体雾化喷雾干燥室的形式创建的喷嘴管的外界空气。气流被加热到吹通过主室汽化喷雾物质的液体体积。固体材料的分子(几乎总是在其自由流动的状态),将被从该废气流通过一个涡流分离和收集样品收集平均。场发射穿过软资讯导读:中草药材品种多,来源也很广,各种各样的中药材又具备多种成分。因为历史的缘故,各地域的中药资源开发利用程度和运用范畴存有着挺大的差别,因此为了中药材的地道和药效,应用低温喷雾干燥机的时候要考虑到以下因素。 中草药材品种多,来源也很广,各种各样的中药材又具备多种成分。因为历史的资讯导读:脉冲燃烧喷雾干燥机,与传统的喷雾干燥机相比,可粒高品质的粉末。在的喷雾干燥技术,在食品,化学品,矿物质和营养补充剂,化学品和塑料电池材料领域,预期生产成本和性能有很大的提高。只要它是一种原料,可以在常规喷雾干燥机进行干燥,也可以是还干,在大多数的情况下脉冲燃烧喷雾干燥机。即使是原料不能在常喷雾干燥机技术现在改进非常广泛,但有些企业在使用中还是知道比较少,用的还是老式的喷雾干燥机,对于现在改进的新的产品知道比较少,喷雾干燥机作业中,干燥用热风进入塔内的温度(热风温度)与出口温度(排风温度)的决定是很重要的。排风温度与产品的水分含量有关,应按产品容许的水分来决定。热风温度越高热效率越高,资讯导读:在典型的YPG系列压力式喷雾干燥机贯通在干燥容器的喷雾喷嘴的有机拒水或含有机溶剂的悬浮液。如果喷射的产品云来在重力的影响下,它是由一个热空气流中干燥。将干燥的材料离开YPG系列压力式喷雾干燥机,并且可以进一步干燥或冷却通过流化床干燥机/冷却器进入集尘器,例如在一个尘过滤器或旋风分离器之前。
