Aiming to develop a sugar cane detrasher by water-course, the separating performance of the trash was examined. The results obtained are as follows.1) The sugar cane variety used in this test was NiF8 and F177. The average density of the rawmaterial cane was above 1.0.2) The average density of the trash (top stem and vagina) was under 1.0, respectively. Comparing varieties NiF8 and F177, the average density of the latter was relatively larger than that of the former.3) The rawmaterial (1-6 portion) could be separated from the trash (top stem 1-2 and vagina 3-5 portion) after 5 or 30 minutes in still water.4) The separating performance of the trash by the water-course generated during the rotation of a wavyshaped impeller was superior.5) The rawmaterial cane, the squeezed cane and the irregular cutted cane could be separated in the lower layer by the water-course. The weight percentage of the separated cane was above 99%, respectively.6) The removing methods of the vagina separated in lower layer (6%) and the rawmaterial separated in middle layer (0.7%) must be found in the near future.
