High-Quality Cane SugarCost-Effective Process Solutions for Mills and Refineries
We have developed optimized and cost-effective ultrafiltration and ion-exchange processes suited to your cane sugar factory strategy:• Production of VPH Cane Raw Sugar at the Cane Mill• Cane sugar stand-alone refineries• Refineries producing high quality liquid sugar for local industrial markets
VHP Cane Raw Sugar at the Mill
Considering that soon 80% of the saccharose produced worldwide will be from cane, Novasep has developed NAP microfiltration processes (New Applexion® Processes), which allows you to produce a higher quality sugar directly at your mill. Our cost-effective solution represents significant savings in capital and operating costs.
The NAP microfiltration of clarified cane juice, combined with both cane juice softening and crystallization enables you to produce “NAP sugar” or VHP cane raw sugar, without sulfitation:• 40% less color• 55% less ash• 20% higher crystallization speed
This sugar can easily be transformed into refined sugar directly at the mill or sold to refineries at a premium.
Microfiltered and soft cane juice can be concentrated in most efficient evaporators in order to reduce energy usage and to make more bagasse available for co-generation.

Cane Sugar Stand-Alone refineries
For cane sugar refineries, decolorization is one of the most critical steps. The objective is to remove color originating from:• Polyphenols, initially present in cane and caramel• Melanoidins• Products from hexose degradation, developed during the refinery process
More than 40,000 tons of refined sugar are produced every day with our optimized ion-exchange decolorization systems, making Novasep the world leader of sugar decolorization.Several innovative regeneration process options enable to optimize your CAPEX vs. OPEX strategy for your ion-echange decolorization system. They provide very low consumption of regenerant and reduce the quantity of effluents.

High Quality Liquid Sugar for Local Markets
The industrial liquid sugar market has significantly developed over the last decade and thus requires optimized processing solutions. Three main production systems exist:a. Production of crystalline refined sugar at the refinery, with shipping
and dissolution to produce liquid sugar at the end-user factoryb. Production of liquid sugar at the refinery, using crystalline refined
sugar as raw materialc. Novasep’s optimized solution: direct production of liquid sugar from
decolorized fine liquor as raw material at the refinery, concurrently with crystalline refined sugar
Novasep’s process by-passes crystallization for a fraction of the production and enables you to produce liquid sugar specifically for local markets, optimi-zing costs and time-to-market.• Flexibility in crystalline refined sugar/liquid sugar production,
depending on the season• Higher value product for specific local market• Potential expansion of the total production capacity of an existing
refinery:- Without any modification of the sugar house- Without generating additional refinery molasses- Parallel processing of fine liquor for producing refined sugar and liquid sugar
• Large-scale production of liquid sugar offers renewed opportunities for complete integration of the liquid sugar process within the main refinery process
