An elevator with flights loads a specific quantity of carrots or potatoes into a rotating drum with a shaped bottom and walls covered with an abrasive.
The rotation brings the potatoes into contact with the abrasive surfaces, which grate their skins.
Detachment of the skin is completed by a shower of water, and continuously drains them away separately.
The loading, peeling and unloading operations are timed. The duration of a processing cycle is about 90 - 120 seconds (variable depending on the loaded product).
