Reducing sugarcane juice reabsorption in sugar mills using mill rolls with internal drains: Greater sucrose extraction and lesser moisture in bagasse* [Full subscriber]

Abstract A technological innovation is presented that minimizes the sugarcane juice reabsorption during the milling cycle, increasing its juice extraction: the XM mill roll. The innovation is based on the Lotus mill roll, but is not built on steel, but rather on cast iron, similar to the conventional shells. The innovation consists of implementing drains directing flow towards the inner part of the mill rolls in order to rapidly separate the bagasse juice during the milling cycle. Hundreds or thousands of nozzles are placed at the root of the mill rolls teeth to capture the liquid and direct it internally…
