  • the outer housing 15 of the tallow extruder extends longitudinally of the hot air passageway 24 while the tallow outlet 18 preferably extends through a lower end of the passageway.
  • the low fat content product is suitably directed by the auger assembly 19 into the agitator 26 of the dehydrator, whereupon it passes into the dehydration tower 27.
  • the inner perforated pipe 12 (see Figs. 4 to 6) is located co-axially within the housing 15 and extends therealong to communicate at it upper end from where it is supported with an inlet hopper 11 and be freely located at its lower end in an annular recess 28 in an end plate 29 suitably apertured at 30 to permit material to pass therethrough.
  • the main auger 14 comprises in this embodiment a hollow shaft member 31 _ supported rotatably at its upper end on a bearing 32 which is itself supported by three radial arms 33 extending outwardly to the hopper 11.
  • the shaft 31 is provided at its lower end with a spigot 34 which extends through the apertured plate 29 to be coupled by a bolt 35 to a hollow tube 36 which is an extension of a shaft 37 supported in bearings 38 at the lower end of the housing 15 and provided in this instance with a gear 39 to enable rotational motion to be transmitted to the shaft 31.
