How does the author use the various literary devices (i.e. simile, hyperbole, etc.) to emphasize Max’s suffering?

Simile:

Hyperbole:

Again, he set two aside and devoured the third. The noise was astounding. Surely, the Führer himself could hear the sound of the orange crush in his mouth. It broke his teeth with every bite.
