| 摘要 |
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.
