Microwave modification of sugar cane to enhance juice extraction during milling † [Full subscriber]

Mechanical shredders are used to rupture the storage parenchyma cells in the pith of the sugar cane stalk to facilitate extraction of the cane juice through the milling tandem. The cane shredder accounts for approximately 20% of the total energy balance in a sugar mill. Shredder hammers also wear quickly during the crushing season and need to be regularly maintained or replaced. These maintenance events interrupt the production schedule of the mill. Studies reported in the literature have revealed that applying intense microwave energy to wood can significantly reduce other processing energy requirements such as pulping or drying. Depending on…
