In the design of the de-huller, the lotus seeds were fed into the de-hulling channel in queue of the seeds with a certain heading orientation by using a screw expeller, and the de-hulling channel composed of two rotating supporting roller and a con-rotating cutting roller was established to realize the de-hulling of seeds. The integrated adjustment unit was designed for the adjustment of the main cutting parameters such as cutting force, cutting depth, two obliquities in horizontal and vertical plane so that the different variety and granularity of seeds were de-hulled.
