The invention provides a negative pressure type walnut shell and kernel separation device and method, which belong to the technical field of walnut shell breaking processing and comprise a feeding barrel, a separation track, a vacuum device, a walnut shell collection device and a walnut kernel collection device; the bottom of the charging barrel is communicated with the top of the separation track, the separation track is of a hollow structure with two open ends, and a preset included angle is formed between the inner bottom surface and the outer bottom surface of the separation track; the first end opening of the separation track is communicated with a vacuum device, the second end opening is communicated with the atmosphere, a walnut shell collecting device communicated with the separation track is arranged at the position, close to the first end opening, of the bottom of the separation track, and a walnut kernel collecting device is arranged at the position, open at the second end, of the separation track; the walnut shells and the walnut kernels move in opposite directions through the pressure difference formed between the negative pressure generated by the vacuum device and the atmospheric pressure; the pressure difference that has evenly stabilized inside the negative pressure formula shell benevolence separator has been guaranteed, and then has realized the high-efficient accurate separation of walnut-meat and walnut shell. |
