Abstract
Proceso para la produccion de partículas con contenido de urea, en el cual las partículas con contenido de urea se producen en una peleteadora que comprende: un dispositivo de alimentacion, una cinta transportadora y un dispositivo para retirar los pélets formados de la cinta. El proceso comprende alimentar un líquido con contenido de urea al dispositivo de alimentacion, desde el cual se dosifican minigotas del líquido del líquido con contenido de urea hacia la cinta, sobre la cual las minigotas con contenido de urea se solidifican y se enfrían a una temperatura de = 55°C y a continuacion las partículas con contenido de urea formadas se retiran de la cinta transportadora.
