Advantages of Spray Dryer--Ruide Drying

Spray drying, the choice dehydration method for the food and pharmaceutical industries, employs an atomizer and a stream of hot gas to produce dry powders, granules or agglomerates from a liquid or slurry. The atomizer disperses liquid feed into fine droplets from which the liquid evaporates, leaving behind solids. Products dried using this process include powdered milk, cake mix, instant coffee, detergent, dyestuff, ceramic powder and yeast extract.

Spray drying's one-step ability to complete the drying process within seconds gives it an edge over other industrial drying techniques. In the food industry, fast drying plays a vital role in ensuring minimum overall flavor loss. The process operates on basic principles and lends itself to automation. The process is versatile and adaptable to a wide range of industries and their feedstock and product specifications. Virtually any feedstock that can be pumped -- solutions, suspensions, slurries, melts, pastes, gels -- can likewise be spray dried.

Spray drying produces powders of controllable particle size and overall quality. Other characteristics manipulated during spray drying include bulk density, degree of crystallinity and residual solvent levels. Being able to control these parameters makes the process desirable for industries like pharmaceuticals, where the optimum absorption of a drug depends greatly on particle size. In dyestuff production, powders of uniform consistency ensure their convenient dispersion into paint suspensions. The food industry puts a premium on moisture content, which determines a product's shelf life.
