what is cryogenic grinding? (with picture)

Cryogenic grinding is a process used in various manufacturing industries and in the study of biology. Also known as freezer milling or freezer grinding, this method is used to process soft or flexible substances by lowering the material's temperature and then breaking the material into smaller particles. Using this process, substances that are
