  • the drum auger 96 has a number of vanes 102 with a fold line 103 as shown in Figures 7a to c.
  • Figures 7b and c are side and end views of the folded vane. This fold allows the auger to scoop and lift the crop when the drum is rotated during the drying operation. Typically the crop is lifted towards the upper third of the drum.
  • Air is blown into the crops during the lifting motion. As the crop drops, moist air is exhausted through conical chamber 81 as shown by the arrows.
  • the inflow of air from chamber 100 into drum 83 is not constant and is timed to coincide with the lifting action of the folded auger vanes. This allows aeration of the crop to be optimised which facilitates drying.
  • This timing may be accomplished by having a plurality of discrete chambers 100 as illustrated in Figure 8. There are eight chambers radiating from central portion 102. As the drum rotates, the open ends 103 of chambers 100 periodically align with the outlet from chamber 98.
  • the drier 80 is also provided with scales 104 for weighing the crop therein.

  • the drying process may also be monitored by the use of a moisture or humidity meter located near the mouth of the conical chamber 81.
  • the speed of rotation, temperature and residence time of the crop may be varied according to variables including type and amount of crop when the crop has been dried, the rotation of the drum is reversed. In the reverse direction, the folded vanes of the drum auger 95 no longer lifts the crop, but instead conveys the crop towards conical chamber 81 for unloading.
  • the harvested and dried crop may be removed from the field immediately after harvesting. This allows the growing crop to be immediately irrigated, fertilized or grazed. The crop may also be dried, packaged or sold immediately. No crop is left lying in the field where it may be subjected to rain damage.
