Comparison of peeling, squeezing and concentration methods for the sugarcane juice production

In this research, various methods of sugarcane peeling, squeezing and juice concentration were compared. The objective was to determine the proper peeling, squeezing and juice concentration techniques for the sugarcane juice production. The experimental results indicated that the sugarcane should be peeled by the abrasive tool and squeezed by the roller in order to achieve high yields with shorter process time. It also appeared that the freeze concentration method applied in this work could not manufacture the high concentrated sugarcane juice. On the other hand, the vacuum evaporation operating at 70°C and vacuum pressure 70 cmHg could concentrate the juice to approximately 60°Brix. Nonetheless, the reconstituted sugarcane juice from the freeze-concentrated specimen was preferred to those from the vacuum evaporation
