Maceration system for milling sugar cane

Abstract

Disclosed is a maceration system of the type generally used in the grinding and juice extraction of sugar cane. The last mill has a roll and feed and discharge bottom rolls with elongated trash plate spanning the space between the bottom rolls. Separate troughs extend below each of the bottom rolls to catch and separate juice therefrom. The top roll has longitudinal flow passageways around it opening into ports in the roll surface and water is introduced through these passgeways to flow into the pulp moving over the trashplate to the discharge roll, and the juice from below the discharge roll is directed to the pulp moving to the feed roll. In the case of multiple mills in tandem, the juice recovered from the feed roll is directed to the top roll passageways of the previous mill and the juice from the discharge roll of that mill is directed to the feed roll thereof.
