In industries such as food and pharmaceuticals, spray dryers are essential drying equipment. It uses atomizers and hot air to produce dry powders, granules or agglomerates from liquids or slurries. The atomizer disperses the liquid feed into fine droplets from which the liquid evaporates, leaving behind a solid. Products dried using this method include milk powder, cake mixes, instant coffee, detergents, dyes, ceramic powders and yeast extracts.
Speed and Versatility
The one-step capability of spray drying can complete the drying process in seconds, which gives it an advantage over other industrial drying techniques. In the food industry, fast drying plays a vital role in ensuring less overall flavor loss. The process operates according to basic principles and is suitable for automation. Versatile and applicable to a variety of industries and their raw material and product specifications. Almost any feedstock that can be pumped—solutions, suspensions, slurries, melts, pastes, gels—can be spray dried.
Quality Control
Spray drying produces powders of controlled particle size and overall quality. Other characteristics of operation during spray drying include bulk density, crystallinity and residual solvent levels. Being able to control these parameters makes the process ideal for industries such as pharmaceuticals, where good drug absorption depends largely on particle size. In dye production, powders of uniform consistency ensure easy dispersion into paint suspensions. The food industry places great emphasis on moisture content, which determines the shelf life of a product.
There is a high demand for spray dryers in various industries. Our products have the advantages of easy installation, durability, long service life and simple maintenance. These can also be customized according to customer specific requirements and details.
