TLDR
In this paper, a spray-drying method for large volumes of detergent slurry in a spraydrying tower is described, which comprises spraying at least a portion of the slurry, cocurrently with air having a specified temperature and velocity range, through uniformly spaced atomizing nozzles into a cylindrically shaped drying zone.Abstract:
A method is provided for spray-drying large volumes of a detergent slurry in a spray-drying tower which comprises spraying at least a portion of the slurry, cocurrently with air having a specified temperature and velocity range, through uniformly spaced atomizing nozzles into a cylindrically shaped drying zone. Any remaining balance of the slurry is sprayed countercurrently into the drying zone at higher levels in the spray tower. Apparatus is provided for practicing this process. Granular detergent compositions having improved physical properties are also disclosed.read more

TL;DR: In this paper, the authors proposed a method for processing a material into a granular product, which involves atomising the suspension, feeding a heat transfer medium (4) in a helical stream into a zone which is situated below the atomising zone, drying the suspension with the aid of the heat transferred medium in cocurrent and in countercurrent motion downwards up to a temperature at which the required product properties are achieved, and ducting off the heat-treated material from the heat treatment zone.
