    Lightweight elevator and advanced secondary cleaning system for cane harvesters : SRDC Final report BS210S
    (2001) Norris, CP
    The goal of this project was the development of a prototype lightweight harvester elevator and integrated secondary cleaning system. The goal was commercially driven and proposed transfer and adaptation of high-speed conveyor technology (from mining and from other agricultural materials handling applications) and advanced pneumatic cleaning concepts to the cane harvester. The design brief targeted enhancing machine performance (ie cane loss, extraneous matter and pour rates) whilst reducing machine weight and improving machine stability. The development has not, however, resulted in a commercially viable prototype. Because of unforeseen difficulties relating to the design adopted for the hugger belt system, the final goals could not be met within the framework of the initial project. When 'pushing the limits' of machine development, problems such as this must be expected, particularly when the development is being undertaken on limited manpower and fiscal budgets. The project, however, has in no way been unsuccessful. Whilst the nominated final goal has not been met, the project has very significantly progressed knowledge relating to the cleaning of cane, and has clearly shown that the concepts embodied in this project have very considerable potential.

    Commercialisation of lightweight elevator and advanced secondary cleaning system for sugarcane harvesters : Final report BSS251
    (2002) Davis, RJ; Norris, CP
    The Australian sugar industry is facing the challenge of increasing extraneous matter (EM), depression of ccs, sugar quality issues, and increasing harvesting and transport costs per tonne of final product. In addition, Likewise, cane loss remains a major background issue. Leslie and Wilson (1996) identified EM as a major contributor to the depression of ccs in the northern canegrowing regions. If low EM is seen as paramount by the industry, either cleaning the cane at the mill in dedicated cleaning plants, or improved performance of cleaning systems on harvesters, is required.Improving the performance of harvester cleaning systems is not easy because a number of fundamental problems exist. Rational review of the function of trash removal from a stream of billets and trash, particularly under wet trash conditions, indicates that effective cleaning is extremely difficult to achieve in one pass through any cleaning system. This is due because tof the interactions between the leaf material and billets of cane.The goal of this project was to development of a pre-production prototype lightweight harvester elevator and integrated secondary cleaning system. The project was commercially driven and built on the knowledge gained from the SRDC-funded project BSS210 in which h. The application of high-speed conveyor technology and advanced pneumatic cleaning concepts were integrated into a cane harvester. The design criteria targeted enhanced machine performance through reduced cane loss and EM, whilst reducing machine weight and improving machine stability.
