PRODUCTION OF POWDERS AND CAPSULES 
Dryer atomizers and prilling towers are industrial plants used to make powders and microcapsules by atomizing liquids which are then dried, frozen, coated or encapsulated.
During spray drying, the liquid is sprayed "atomized" into droplets by means of a rotating disk SPRAI sprayer in a vertical cylindrical chamber, in contact with a stream of hot air, in order to evaporate the liquid. 'water. The droplets are then dried to a dry powder before falling on the lower walls of the cylinder. The separation of the powder and the moist air then takes place in cyclones.
During freezing by atomization, the liquid is heated and then sprayed "atomized" into droplets by means of a SPRAI sprayer with a rotating disc in a vertical cylindrical chamber, in contact with a current of cold air, in order to to freeze the droplets before falling on the lower walls of the cylinder.
