Study on Juice Extraction from Sweet Sorghum

Abstract

A roll-belt extractor was designed and produced in order to explore the application of chop-harvested sweet sorghum. Extraction experiments were also conducted. The extraction ratio ((juice mass/input mass)×100%) of the trial product might increase with reduced cutting length, decreased drive roller speed, and increased feed rate. The average extraction ratio was 15.6% when the cutting length was set to 17mm, the drive roller speed to 17.5rpm, and the feed rate to 823kg/h (maximum). In addition, we also investigated the application of the obtained cake and juice. We concluded that the silage from the cake was good fodder using the sensory method. The obtained juice contained multifarious sugars, and the product ratio of fermentation ethanol (2.45%) was higher.
