System and process for refining sugar

A system (10, 110) and process for refining raw sugar, comprising a melting unit (16, 116) configured to receive the raw sugar and an eluent to produce a melt liquor, a decolorization unit (24, 124) configured to receive the melt liquor and to produce a fine liquor, a crystallization unit (36, 136) configured to fractionate high-purity crystalline sucrose from the fine liquor and to provide a run-off syrup, a softening unit (46, 146) configured to receive the run-off syrup to produce a softened syrup, at least one separation unit (48, 148) configured to receive the softened syrup to produce a low-invert sucrose product, and a recycle line (52, 152) configured to relay the low-invert sucrose product from the at least one separation unit (48, 148) to the melting unit (16, 116).
