Particle formation and drying are the work of fluidized bed dryer and this whole process is called as spray drying. Spray dryer's versatility is the reason which have made its application in galore of fields. This device also ensures the quality of the end product.
Spray drying is the most extensively used industrial mechanism committed in particle formation and drying. This activity goes very much with the continuous production of the dry solids, which can be in either powder, granulate or agglomerate form. Solutions, pump able suspensions and solutions are the source of liquid feed stocks on which the spray drying technique is used to extract the solid. Particle size distribution, residual moisture content, particle shape and bulk density of the finished products comply with quality standards, which makes spray dryer an ideal apparatus.
The liquid feed stocks are broken down into small atoms and spray dryer convert the atoms into spray of rotary dryer for sale and then this droplets are contacted with the hot air in a drying chamber. Spray dryers are equipped with some type of atomizer or spray nozzle, which are used to disperse the liquid or slurry into constrained drop size spray and hence the quality is maintained. Controlled temperature and airflow conditions are maintained with the great care for the evaporation of moisture from the droplets and also the formation of dry particles. The end product, powder is being continuously ejected. The drying features of the product and the powder's specifications are main criteria on which the selection of operating conditions and dryer's design are being made.
There are many spray dryers manufactures which are fully engaged in the fabrication of this modern machine and offer a quality product. Spray dryers are capable of drying a product very instantly when compared to other techniques of drying and this being the reason that the spray dryer exporters are in high demand. Further, the demand for spray dryer suppliers are also on rise because this process is preferred over crystallization technique of amorphous powders during the process of drying as the the temperature effects are important depending on drying residence times.
Spray dryer have found its way into food industry like making of milk powder, coffee, tea, eggs, cereal, spice and flavoring. The pharmaceutical industry engaged into antibiotics, medical ingredients and additives use the spray dryer and various other industrial process like paint pigments, ceramic materials and catalyst supports widely use this technique. A very common daily life usage is use of this process in the manufacturing of continuous drying equipment like Rasna, which is a spray dry of various ingredients and is a popular beverage. Skim milk techniques are presently being used around the world to produce milk powder, which is also a big example of spray drying process.
