An apparatus can include a hollow tube, central shaft, agitation components, and bidirectional fluted auger. The hollow tube can have an inlet, outlet, and longitudinal central axis, and can facilitate the conveyance of foodstuff materials from the inlet to the outlet. The central shaft can extend along the longitudinal axis and can be rotationally driven both clockwise and counterclockwise. The agitation components can be coupled to the central shaft and can agitate and mix foodstuff materials being conveyed along the hollow tube. The bidirectional fluted auger can be coupled to the central shaft proximate the outlet, can rotate with the central shaft when the central shaft is rotationally driven, and can have a flow rate limiting inner cylinder, clockwise-progressing flute features, and counterclockwise-progressing flute features. The clockwise and counterclockwise progressing flute features can convey foodstuff materials toward the outlet when the bidirectional fluted auger is rotated clockwise or counterclockwise.

A system and method for feeding a high volume of low-bulk-density and pressure-sensitive feedstocks into a pressurized environment. The system includes a lock hopper filling system, one or more lock hoppers, a feed bin, and a feeder. The methods involve using such a system to feed bulk materials into a pressurized environment by feeding bulk material from a low pressure into the surge bin, filling the one or more lock hoppers from the surge bin, operating the lock hoppers, and discharging lock hoppers into feed bin, and discharging feed bin into the high-pressure zone using feeder.
