The invention provides an apparatus capable of automatically removing the outer epidermis of a squid slice, belonging to the field of food automation. The apparatus is composed of a conveyor belt, a sensor, a power-driven press roller and an epidermis-removing assembly, wherein the sensor is arranged on the conveyor belt, the power-driven press roller is arranged above the central part of the conveyor belt, and the epidermis-removing assembly is arranged below the central part of the conveyor belt. During operation of the apparatus, the squid slice is put on the conveyor belt with the outer epidermis downwardly laid. The apparatus provided by the invention is capable of automatically removing the outer epidermis; a scraper assembly is ingenious in structure and simulates the procedure of peeling off the outer epidermis of a squid in manual epidermis removal; the scraper assembly is fast in epidermis removal speed and good in epidermis removal effect and maximally reduces damage to and waste of squid meat; and after completion of epidermis removal, a rolling brush is employed for automatic cleaning of the scraper assembly, so automatic and continuous operation of the apparatus is guaranteed, production efficiency is improved, labor force is liberated, and labor cost is reduced.
