Method for producing clarified juice, packagible juice, ethanol and sugar from sugarcane and system thereof

摘要

The present invention provides a method and system for manufacturing clarified juice from sugarcane without using sulfitation process and with less heating. The method comprises step of steps of: washing sugarcane with water comprising biocide before passing through cutter and shredders for removing mud and reducing microbial population; spraying biocide on the cut and prepared sugarcane to reduce the microbial activity; adding biocide while milling of the sugarcane or in juice collectors to have control over the microbial growth; filtering the juice to remove floating/suspended matters; heating the filtered juice at about 35-85 deg C; mixing one or more coagulating and flocculating agents for coagulation of suspended solids; and separating the coagulated solids to obtain clarified juice. This juice can be further treated to manufacture ethanol, juice for packaging having shelf life of about six months and sugar without using conventional sulfitation treatment.
