Spray Dryers – DryTech International

Spray Dryers are designed for drying of slurries and liquids. Sprays Dryers can be configured in numerous ways from co-current to counter-current and the slurry or liquid can be introduced to the process via high pressure atomizing nozzles or high-speed wheel atomizers. Capacities range from 100 kg/hr to in excess of 30 tph.

Spray Dryer Atomization, Spray Drying.

2021-6-10 · ATOMIZATION. Producing droplets of specific size and surface area by atomization is the most critical step in the spray drying process. The degree of atomization, under a set of spray drying conditions, controls the drying rate, and therefore the required particle residence time, and therefore the spray dryer size.
