FUNDAMENTALS OF SPRAY DRYING The purpose of spray drying is to produce a powdered or granular product in one step by drying an - 'atomized' liquid feed (solution, suspension, or emulsion) in heated air or other gaseous medium. By atomizing the feed into fine droplets a very large surface area per unit mass is generated with a very short path for heat and mass transfer. The heated air supplies latent heat of evaporation to the droplets and brings about rapid drying which in turn brings about rapid cooling of the drying gas. At the same time the particle temperature is kept low by adiabatic Cooling. Drying can take place in a very short time, typically 5-20 seconds.Spray dried particles are usually spheroidal, which give the product excellent flow characteristics. Size of the dried product particle depends on the size of the droplet from the atomizers. Different atomizers produce different particle size distribution and spray patterns. The drying air flow pattern must be carefully selected for optimum performance. Atomization is fundamental to Spray drying - nearly all operating and product characteristics are affected by it. To atomize the feed solution or slurry, high shear forces are applied by one of the following methods:Centrifugal- accelerating the liquid off the edge of a spinning wheel.Pressure Nozzle - Spinning the liquid at high velocity through a small orifice.Pneumatic Nozzle - Impinging a high velocity air stream on a slow moving liquidKILBURN TOWER SPRAY DRYER These versatile tower spray dryers are used for efficient drying of inorganics, catalysts, ceramics, powdered metals, pigments, dyes and similar materials. The maximum air temperature is 530 Degree Celsius when using a direct-fired gas heater. Evaporation capacity varies depending on the inlet /outlet air temperature profile and composition of the feed. The units employ cocurrent or mixed flow (counter-current) drying principle in an "open cycle" concept.Atomization is performed by either single -fluid or two-fluid nozzles located at the top or bottom of the tower. Particle size obtained ranges upto 170 microns depending on feed composition and operating parameters. The unit is constructed out of stainless steel. Product is collected at two points-chamber bottom & cyclone collector.PILOT PLANT OF SPRAY DRYER Kilburn Test Centre has a versatile spray drying & processing equipment installed at its Mumbai works. Products can be thoroughiy and accurately tested prior to the design and engineering of production system.Considering all parameters like energy consumption, space requirements, product quality expectations, drying time, heat / temperature sensitivity of product, Kilburn can recommend, design and engineer, Spray Dryer and its systems to precisely suit customer application and requirements.The Pilot Plant at the Kilburn test centre specifically ensures an accurate scale-up from the laboratory to the production units.PRODUCTS HANDLED Fluid Cracking Catalyst Micro-Crystalline Powders Magnesium chloride Ceramic Clay E-PVC Coffee Milk资讯导读:喷雾干燥器的雾化装置一般有离心式、压力式以及气流式。 1.制药行业对喷雾干燥机的要求 1.1雾化装置 喷雾干燥器的雾化装置一般有离心式、压力式以及气流式。离心式雾化器其离心盘的传动轴部分处干燥室内外,防止轴封之细粒脱落比较困难;压力式雾化系统其料液要经过高压泵压送。运作时活资讯导读:传统的喷雾干燥机以高效的方式将液体转化为粉末。它在乳业、食品和化学工业等多个领域得到广泛应用,并因其业绩而闻名。 传统的喷雾干燥机以高效的方式将液体转化为粉末。它在乳业、食品和化学工业等多个领域得到广泛应用,并因其业绩而闻名。 传统的喷雾干燥机专为符合特定行业标准和要资讯导读:低聚木糖营养八宝粥是以南瓜为主要原料,配以低热量的甜味剂—低聚木糖、优质糯米、薏仁米、麦仁等,采用科学的生产工艺试制出的适合糖尿病患者及中老年人食用的南瓜粥。南瓜粥不仅营养价值高,而且有南瓜特有的清香味及糯米香,口味柔和,口感细腻、香甜;色泽金黄,品质极佳。 低聚木糖营养八资讯导读:“欧力多”——低聚异麦芽糖是以玉米淀粉为原料,经过特殊酶的作用而制成的,是食品行业、焙烤行业的功能性配料。具有柔和的甜味,可用来代替蔗糖,适合于食品形成,加工时操作简单,比饴糖易于操作。低聚糖对酸、热非常稳定,具有^的保持水分的能力,发挥其各种特性和抗龋齿性。这种功能糖促进肠道内双歧杆菌的资讯导读:有许多原因可能导致干燥机不能干燥或升温,在拨打专业人员的饿维修电话之前,请务必先看看几件事情,看看能否自己解决。 有许多原因可能导致干燥机不能干燥或升温,在拨打专业人员的饿维修电话之前,请务必先看看几件事情,看看能否自己解决。问题可能在于加热元件发生故障,或热过载切断(机器
