Abstract

Apparatus for proofing lumps of dough comprises a series of elongate conveyors for successively transporting the lumps of dough, equipment for mounting the elongate conveyors in a spatially staggered relationship, a plurality of auxiliary conveying systems each associated with a different pair of elongate conveyors for transferring lumps of dough from an end of one conveyor of the particular pair to a portion of the other conveyor of that particular pair, equipment for feeding lumps of dough to the first and from the last elongate conveyor in the series, an enclosure for the elongate conveyors and the auxiliary conveying systems, and equipment for providing inside the enclosure a proofing environment for the lumps of dough. Said auxiliary conveying systems include a further endless conveyor loop being smaller than each of said conveyor loops of said series of elongate conveyors, equipment for mounting said further conveyor loop in the vicinity of an adjacent pair of elongate conveyors at a spacing from the adjacent pair of elongate conveyors sufficient for the transfer of lumps of dough between said further endless conveyor loop and the adjacent pair of elongate conveyors, equipment for driving said further endless conveyor loop and said distinct endless conveyor loops in mutual synchronism, said mounting equipment including a curved support for guiding said further conveyor loop in a concave path adjacent the latter pair of elongate conveyors and a spaced pair of retaining strips for retaining and guiding edge portions of said further conveyor loop in said concave path.
