噴霧干燥的顆粒通常是球形，得到產(chǎn)物的優(yōu)異的流動(dòng)特性。干燥產(chǎn)物顆粒的大小取決于從霧化器的液滴的大小。不同的霧化器產(chǎn)生不同的顆粒尺寸分布和噴霧圖形。干燥的空氣流動(dòng)模式，必須經(jīng)過(guò)精心挑選，以獲得^佳的性能。   霧化噴霧干燥是根本  - 幾乎所有的操作系統(tǒng)和產(chǎn)品特性都受到它的影響。要霧化的進(jìn)料溶液或淤漿，高剪切力施加由下面的方法之一：

SPRAY DRYERS   KILBURN designs, manufactures & installs Spray Dryers based on product trials taken in the Pilot Plants at its Test Centre.   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 liquid

KILBURN 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.
