Spray drying is method of dehydrating fluids, solutions and thin slurries, it converts the fluids or slurries to powder form. Liquid or slurry material to be dehydrated is sprayed in the form of a fine droplet dispersion into hot airstream. Both air and material either travel in parallel or counterflow. Drying in spray dryer occurs at very fast rate so that the contact of material to heat is not for longer time hence its does not damage the heat selectivity materials and becomes ideal for drying such materials.
At Kerone, we produce spray dryers that can be fall in various range based on the complexity of design from simple to very complex, all depends on the fluid or slurries under processing. The difference in the designs rare the in atomization, pattern of airstream, air heating systems/technique, and separation and collection unit. Spray dryers mainly comprises of drying chamber, atomization and dispersion means to feed fluid in small droplets into the drying chamber, air heating system, and separation unit to collect dried output.
Hot air can be achieved by the means of direct firing of gas or by the means of fuels or uses of heat exchangers. Pressure spray heads, nozzles, and centrifugal atomizers are applied for distribution of the fluid elements. Processed product is separated by using cyclone separators in which the air is applied laterally at the top or settling chamber in which the direction of airflow is reversed to achieve separation of dried products by means of gravity. Below schematic depict both the approaches.
Kerone is having meticulous experience when it comes to design and built spray drying unit that can be utilised for various application in varying industries. So far we have helped tons of or clients with their drying needs. Our team of engineers and quality manufacturing process helps us to achieve the accuracy and product quality.
