The invention relate to a haw kernel removing system. The haw kernel removing system comprises a plate chain conveyor, wherein a feed hopper, a haw positioning device, a kernel punching device and a material receiving tank are sequentially arranged on the plate chain conveyor in the running direction. According to the haw kernel removing system disclosed by the invention, in the haw positioning region, a water distributing device is used for injecting water to positioning holes, so that haws float on the surface of water; due to the appearance characteristics of the haws, after the haws in the positioning holes float, the directions of fruit stems are downward completely; then, inner holes with spirals are used for draining water injected in the positioning holes, the positions of the haws in the positioning holes are completely consistent, so that automatic loading and positioning of the haws are realized; because the wall surfaces of the positioning holes are cambered, in the same positioning hole, haws of different size ranges can be positioned; the haws enter kernel punching positions, so that kernels are removed, when punches are used for punching the kernels, inner pushing blocks arranged in inner holes of the punches firstly press concavities in the centers of the tops of the haws under the action of spring force, so that fixing of the haws is realized; then the kernels are punched, so that the breaking rate of the haws is reduced.
