The invention relates to a continuous rolling tube high-pressure water spraying walnut kernel peeling device, which comprises a material inlet hopper, a rolling tube, a high-pressure water pipe, a material outlet hopper, a motor, a water collecting hopper and a water collecting tank, wherein a spiral scraping plate is arranged in the rolling tube, walnut kernels are pushed from a material inlet to a material outlet, the high-pressure water pipe is arranged in the axial direction of the rolling tube and is positioned above the axial direction, a plurality of high-pressure water spray openings are symmetrically arranged under the water pipe, and the rolling tube is driven by a motive power system. The water collecting bank is positioned under the rolling tube, a filter net is arranged on the water collecting tank, the walnut kernel flushing and spraying is completed through high-pressure water, the water enters the water collecting tank through the water collecting hopper and the filter screen, the water in the water collecting tank enters the high-pressure water pipe arranged in the rolling tube after the pressure boosting via a centrifugal pump, and the water consumption circulation is formed. The continuous walnut kernel peeling can be realized, the peeling efficiency is high, the daily yield is high, the peeling is thorough and uniform, in addition, the peeling, the separation and the cleaning are combined, the production steps are saved, meanwhile, the circulation water is adopted, the water resource saving is realized, and the device is suitable for industrial mass walnut kernel peeling production.
