The invention provides a shriveled grain extraction device and a shriveled grain extraction process, which are used for extracting shriveled grains from a grain mixture. The shriveled grain extracting device comprises a stone removing machine, the stone removing machine is used for removing stones in the grain mixture, the shriveled grain extracting device further comprises a specific gravity machine, the specific gravity machine is arranged on the downstream portion of the stone removing machine, and the specific gravity machine is used for separating out shriveled grains from the grain mixture subjected to stone removal through the stone removing machine. Through preliminary grading of the stoning machine, rough selection is conducted on a grain mixture, the amount of materials mixed with shriveled grains is reduced, fine selection is conducted through the specific gravity machine with the specific gravity as the index, the shriveled grains are extracted, and therefore the shriveled grains are extracted. 提供
