Qualfloc™ PAM Flocculants for Sugar Industry
Sugar is produced by processing sugar
beets or cane. Basically the process involves the following steps: Extraction
of the cane juice, purifying the juice, concentration of the juice to syrup by
evaporation, crystallization of sugar from the syrup, and finally separation
and drying of the sugar crystals.
Mixed juice from the extraction mills or diffuser is
purified by adding lime and flocculants (Qualfloc™–W series) with heat. The lime (calcium
hydroxide) forms a calcium saccharate compound. The heat and lime will kill
enzymes in the juice and increases the pH from 5-6.5 to neutral. pH control is
very important throughout the sugar manufacturing process.
When the juice is heated up to 99 to 104°C, the neutralized juice
is treated with flocculants and then pumped to a purifying vessel where the mud
settles and the purified liquid overflows. Then decolourants are used here (Qualfloc 110W or 111W) for color removal
(both products can also be used for purification in sugar refinery). Purified
juice is pumped to the evaporation stage for further processing.
