Abstract
The invention pertains to a method of making urea-containing particles wherein with a lower degree of cooling, high mechanical strengths are obtained. The method comprises the steps of (a) providing a first polymerlayer; (b) feeding urea droplets onto said first polymer layer, (c) cooling the droplets provided on the first polymer layer to a temperature between 55° C. and 120° C.; (d) applying a second polymer layer onto the first polymer layer comprising the droplets so as to form encapsulated urea droplets; and (e) separating the encapsulated urea droplets.
