The invention discloses a citrus peeler, comprising a machine frame, a skin cutting mechanism and a peeling mechanism, wherein the skin cutting mechanism and the peeling mechanism are arranged on the machine frame; an orange peel collector is arranged below the peeling mechanism, which comprises a plurality of peeling roller sets continuously arranged; each peeling roller set consists of a fixing position peeling roller and an adjustable position peeling roller; the fixing position peeling rollers are respectively and rotationally erected on the machine frame side plates at the two sides of the machine frame and connected with a synchronous rotation through a chain transmission; the two ends of the adjustable position peeling roller are mounted in the waist-like holes of the machine frame side plates at the two sides of the machine frame and sleeved with connecting rings; the connecting rings are connected with the machine frame side plates through a spring; the adjustable position peeling roller is connected with the synchronous rotation through the chain transmission; and the fixing position peeling roller and the adjustable position peeling roller are in transmission connection with a first drive motor so as to realize rolling rotation. The technical scheme can adjust the distance among the peeling rollers automatically according to the thickness of citrus skin and improve the peeling problems caused by nonuniform citrus skin.
