2106668 9216299 PCTABS00016 A material feeding and measuring device (10) includes a housing (18) defining an interior cavity or bin (30) and having a plurality of agitators (42) and an auger (46) rotatably mounted therein. The agitators (42) are arranged as a first upper row and take the form of a plurality of rotatably mounted rods (48) extending across the bin (30). Each of the rods (48) includes a plurality of tines (54) extending radially outwardly. A lower level of agitators (44), having the same form, are provided adjacent the bottom of the bin (30). An auger (46) is rotatably mounted near the bottom center of the bin (30). The auger (46) extends a slight distance out of the bin (30) into an exit flange (66) which surrounds the periphery of the auger (46). A blower (74) and conduit (80) are arranged to cause an airstream to flow across the end of the exit flange (66) to entrain the material in the airstream for conveyance. The entire housing (18) is mounted upon load cells (94) which are operatively connected to an electronic control device (92). In operation, compressed or partially compressed material is placed within the bin (18) and the initial weight determined. The desired quantity and/or rate of material to be processed is then input to the control device (92), which automatically starts operation of the device (10). The control device (92) monitors the load cells (94) to adjust the operating speed of the motor (58) driving the auger (46) and/or agitators (44) to control the output from the device (10). Upon dispensing the desired amount of material, the control device (92) ends motor (58) operation, and thus dispensing.
