Patent
CA 2452714
The invention relates to a method for directly cooling fine-particle, powdery solid substances by using a cooling medium provided in the form of low-boiling condensed gases or of cold gases obtained therefrom, whereupon bulk material packings are subsequently filled with these solid substances. The invention also relates to a device for directly cooling the fine-particle, powdery solid substances and to fine-particle, powdery solid substances, which are located inside bulk material packings and which, compared to air, have a lower oxygen content in the gas phase between the solid substance particles.
L'invention concerne un procédé de refroidissement direct de solides en fines particules sous forme de poudre, selon lequel on utilise un fluide de refroidissement sous la forme de gaz condensés à bas point d'ébullition ou de gaz froids obtenus à partir de ceux-ci, puis on verse lesdits solides dans des emballages pour matériaux en vrac. L'invention concerne également un dispositif de refroidissement direct de solides en fines particules sous forme de poudre, ainsi que des solides en fines particules sous forme de poudre se trouvant dans des emballages pour matériaux en vrac et présentant, par rapport à l'air, une teneur en oxygène plus faible dans la phase gazeuse, entre les particules de solide.
