How does a mechanical deboner separate edible poultry material from bones?

In poultry processing, a mechanical deboner—also known as a meat-bone separator—is used to recover edible tissue from materials such as backs, necks, and bones.

The machine functions by continuously pressing crushed meat and bone material against a screen. Because the edible, soft materials are pliable, they are forced through the openings of the screen, while the harder bone fragments are retained and separated. The resulting product is a minced meat with a texture similar to ground beef, which is frequently utilized in the production of processed items like frankfurters and bologna.1
