Robust and aggressive designed chopper systems with more blades have been the answer to faster and more productive cane harvesters as contractors and operators look to save time and money to get the harvesting done and dusted as quickly and efficiently as possible. This comes at a cost to the grower and miller as a portion of the crop they get paid for is crushed, damaged and sucked out the extractor in a process we have come to accept in the desire for more bin weights, more tonnes per hour and savings in labour costs.
Mackay based engineering firm, EHS Manufacturing, are known for their innovation and ability in the design and adaption of harvesting equipment to keep the Australian Sugar Industry as world leaders in harvesting technology and best practice. Their latest product development is the most significant and successful change in cane harvester chopper design since rotary differential chop was introduced. This is a welcome improvement as the industry becomes increasingly aware of the sugar losses of current harvesting practices.
The EHS MaxiChop with a patented wedge blade clamp can now provide more blade security and clamping force than ever before allowing a huge 106mm of free ‘clamp to clamp’ gap in the cut position. The free flow open throat design gives the contractor/harvester operator the best of both worlds allowing the increase in productivity and billet quality whilst minimising the juicing/squeezing of the billet ends in the chopping process. This provides maximum profitability for the contractor, grower and miller with the purpose in mind of sugar recovery by all parties involved in the process.
“to ensure we are crushing our cane at the Mill and not in the harvester”
A grower/contractor in NSW uses the original EHS concept prototype which formed the basis of this new innovation. These chopper drums have just finished their 8th season in their 2nd brand new harvester that each have cut in excess of 80,000 tonnes per season. In 8 years the EHS chopper drums have not been touched. No hardfacing – No remachining – all due to the drums have minimal contact with the Sugarcane.
Early testing comparisons of the system showed a decrease in mutilated billets from up to 7% in a standard harvester down to 0.1% in the EHS MaxiChop. Tests also showed damaged billets decreased by 6% and an actual juice loss decrease of 25%. With further testing and positive feedback of the new batch of choppers that have completed the 2015 season, the noticeable lack of juice and mud in the chopper and extractor area is sure visual evidence of the change in this process to ensure we are crushing our cane at the mill and not in the harvester.
