A new paradigm for enhanced industry profitability: Post-harvest cane cleaning* [Full subscriber]

Abstract Increasing harvester pour rate is a common strategy for reducing direct harvesting costs. However, high pour rates also reduce the effectiveness of harvester cleaning systems, and exacerbate cane loss at high extractor speeds. The value lost to these side effects has significantly impacted industry profitability over the past 15–20 years. Higher trashy extraneous matter (EM) levels associated with this increase in harvester pour rate increase fibre and impurity levels at the mill, resulting in reduced milling rates and extraction efficiency, increased sugar recovery losses in the process house and reduced sugar quality indicators. Simply returning to lower pour rates…
