Spray Dryer Residence Time Calculation

Spray Dryer Residence Time Calculation

After Dryer / After Cooler for spray drying processes The list is only partial but already very long. Many industries use spray drying because it offers a continuous drying technique, with a very short residence time in temperature, thus allowing, if the spray drying system is well tuned, to dry heat sensitive components.

Apr 01, 2001 The atomizer is a critical component of the spray dryer. Producing droplets of specific size and surface area by atomization is a critical step in the spray drying process, Bayliss said. The degree of atomization influences the drying rate, and therefore the required particle residence time, and therefore the dryer size.

Apr 01, 2008 The dryers have relatively short residence times. Varying the gas velocity within the dryer can alter the residence time inside the dryer. Spray dryers typically employ induced-draft fans to extract the moisture-laden air from the system. In some instances, special fans are installed to achieve dryer-specific operations such as air sweeps.
