When the auger 22 rotates, the spiral part 221 is rotated to continuously convey the meat materials downwards, so that the unidirectional rotation structure 43 has the effect of preventing the meat materials from being driven upwards under the reverse rotation action of the spiral part 221 when the auger 22 reversely rotates, and preventing the meat materials from being far away from the feeding mechanism 3.
