Atomization techniques in spray drying: A Review

Mounika E, Sivamma P and Snehitha R
Spray drying is a method of particle production by transformation of a fluid material into dried particles. Spray dryers can dry a product very quickly compared to other methods of drying. They also turn a solution or slurry into a dried powder in a single step, which can be advantageous for profit maximization and process simplification. The atomizing device, which forms the spray is called atomizer is the ‘heart’ of the spray drying process. The atomization of liquid into fine droplets increases the surface area there by it leads greater heat and mass transfer between the heated drying gas and the liquid particles. Different atomization techniques such as centrifugal, pressure, hydraulic pneumatic, ultrasonic and electrostatic/electrohydrodynamic atomizers were covered in this review.
