A METHOD FOR SIMULTANEOUS CLARIFICATION AND DECOLOURISATION OF SUGARCANE JUICE WITHOUT USING ANY CHEMICALS FOR ANY PURPOSE USING FLAT MEMBRANE ULTRAFILTRATION MODULE

摘要

A method for simultaneous clarification and decolourisation of sugarcane juice using an ultrafiltration flat membrane module configuration and without using any type of chemicals for any type for altering any characteristics of the juice received as such comprising the steps of extracting cane juice from cane stock, storing the sugarcane juice to facilitate withdrawal, pumping the stored sugarcane juice into specific ultrafiltration configuration of flat membrane module ultrafilter at a predetermined pressure and at ambient temperature. Adjusting the pressure within the specific ultrafiltration configuration of Flat Membrane module to fetch optimum flow of refined cane sugar, collecting the refined sugarcane juice, collecting the rejected stream wherein the sugarcane juice is simultaneously clarified and decolourised. The molecular weight cut off characteristics of ultrafiltration flat membrane module is in the range of 8000 to 20000 and the material of construction of the membrane is anyone of PAN, PS, PA.
