Delivery of sugar beets. After being harvested, the beets are transported to sugar factories.
Spot checks. The beets are spot checked on arrival. The grower is paid according to the quantity of clean beets and their sugar content.
Washing. The beets are weighed and tipped into large piles. From here, they are transported to the beet washer to remove stones and gravel.
Cutting. To extract the sugar, the beets are cut into cossettes – thin strips resembling french fries.
Diffusion. To extract the sugar from the beets, the cossettes are run through water warmed to 70°C. The pulp that remains after the sugar has been extracted (beet pulp) is made into animal feed and other products.
Purifying the sugar juice. The warm sugar juice (raw juice) contains roughly 15% sugar, but also contains 1-2% impurities (non-sugars), which must be removed. This is done using lime.
Thin juice is reduced to thick juice. The sugar juice, now a thin, pale yellow liquid, is called thin juice. The juice is placed in an evaporator, which boils away the water to make the juice thicker. The resulting liquid, called thick juice, contains approximately 70% sugar.
Crystallisation. The thick juice is pumped to large boiling stations, where tiny sugar crystals form in it.
Centrifugal spinning. The thick, brown juice, which is now called massecuite, is spun in a centrifuge to separate the white sugar from the brown syrup. The syrup is returned to the boiling station and boiled again until there is no more sugar left to extract.
Molasses. The remaining product is called molasses. Its sugar content is too low to yield any more sugar. Molasses is used for making animal feed, yeast and spirits.
Ready for use. Finally, the sugar is dried and stored in a silo. The silos are completely full after the beet campaign, but will gradually be emptied during the year as the sugar is sold to shops, industries and on export.
