To provide the subject feeder enabling fixed-density and fixed-quantity cooked rice feed to the molding mechanisms of a food molding machine and ensuring uniform products of constant weight to be easily yielded.

This feeder is designed to convey cooked rice A fed from the preceding process in raised density and dispense it at a specified quantity each to molding mechanisms 14, 15. In this feeder. counterrotating several pairs of left and right slant longitudinal roller conveyors 9, 9 axially supported symmetrically and tiltedly so that cooked rice A can be conveyed while gradually raising its density and conterrotating several pairs of left and right vertical roller conveyors 10, 10 so that the cooked rice A can be conveyed downward through compressing it to a constant density are collocatedly set up in a vertical way. Besides, the outer periphery of part or the whole of the respective rollers of the roller conveyors is axially provided with plural projections 12 for feeding cooked rice.
