Abstract (en)
[origin: EP0707078A1] 1 - Industry concerned : Cane Sugar Manufacture 2 - Part of the process to which the invention pertains : Extraction of the sugar cane juice. 3 - In the prepared raw material (shredded cane) up to 94 % of the juice containing cells are open. If has a low bulk density and high void volume (filled with air> The gist of the invention is to take advantage of this specific structure to improve the efficiency of the extraction process by : Avoiding compaction to maintain high percolation rate Filling the voids with recirculated juice thus turning the solid mass of shredded cane into a free flowing mixture of cane and juice. Replacing,in three stages,the thick juice of cane by thinner juices and finally by water,in a true plug flow displacement process. Improving the efficiency the solid/liquid separation between stages by increasing hydrostatic head between the liquid mass in the extractor and the discharge tank. <IMAGE>
