METHOD FOR COATING SOLID PARTICLES WITH A THERMOFUSIBLE AGENT, AND RESULTING COATED SOLID PARTICLES |
摘要 |
The invention concerns a method for coating solid particles with a thermofusible agent which consists in: fluidizing the solid particles in an ascending air movement in spiral rotation to obtain a homogeneous individualised distribution of the particles in the air fluidized bed, the temperature of the air fluidized bed being lower than the melting point of the thermofusible agent; spraying on the particles the melted thermofusible agent in the form of atomised droplets, said droplets being distributed in a spraying cone included in an air zone, whereof the temperature enables to maintain, throughout said spraying process, a temperature of the thermofusible agent substantially equal its melting point, the spraying being carried out in the same direction and tangentially to the movement followed by the solid particles; finally, after the coating process, cooling the resulting coated particles so as to solidify the thermofusible agent around the particles.
