Refining & Processing
Grown in over countries, over million metric tons of sugar is produced each year. But how is it extracted from sugar cane and produced into pure sugar?
Our team of Market Analysis experts delve deeper to provide more insight on sugar production. Discover more about sugar trading from the experts at Czarnikow. Sugar cane is grown in warm to tropical areas of the world, with Brazil, India, Thailand, China and Australia as the leading producers.
Each sugar cane plantation has multiple fields — all at different stages of cane production to ensure that there is always cane available to supply the mill. From planting the cane through to harvest, the process can take up to 18 months. Preparation of the cane ahead of it being planted is vital. The leaves are removed from the cane and then cut into 20cm tranches. The field row is then prepared with incisions made in the field at approximately cm in width. The cane is then placed inside the hole horizontally and left to grow.
The success of producing sugar begins with healthy soil. This is done with the addition of nutrients and lots of water.
Sugar Cane takes approximately months to mature. During this time, it is important that the cane is treated with pesticides and fertiliser to enable a healthy and high yielding sugar cane. Cane sugar does not need to be re-planted, as only the top of the plant is removed during harvest. There are two ways that sugar cane can be harvested — manually and mechanised. The manual harvest process begins with the sugar cane fields being torched. This removes all the leaves so that the cane can then be manually chopped to the ground by a team of farmers.
However, this process takes days and the burning of the cane leaves results in wildlife and a reduction in the quality of the sucrose in the cane. Once the cane has been manually harvested, it is put on a truck by hand and driven to the mill. The alternative way to harvest sugar cane — the mechanised harvest — involves a machine extracting the cane as it travels across the field, whilst loading it into a truck. Mechanised harvesting is seen as the future of cane harvesting.
This is primarily because it is not only better for the environment and wildlife, but it is a more efficient operation taking the cane to the mill. Mechanised harvesting reduces the time of an average harvest by up to three-quarters, from hours to only hours. This increase in efficiency for the harvest means higher sucrose yields and larger profits for the plantations.
Once the sugar cane is transported to the mill, it has to be weighed and examined to confirm how much cane has been delivered and to determine the TRS Total Recoverable Sugar content of the cane. The TRS content grades the quality of the cane — therefore it has a direct impact on the price paid for it, and the amount it will be sold for. Once the cane has been graded, it is washed to remove any impurities ahead of being processed.
The cleaning of the cane can be done wet or dry. Dry cleaning is the preferred method as it is more environmentally friendly and does not affect the TRS content. Once the cane has been dried, it is chopped before it is crushed in big roller mills. This process removes the sugar cane juice. The juice is the valuable extract as it is used for sugar and ethanol production. The sugar cane juice is then sent for clarification. The juice is treated for precipitate elimination via coagulation and sedimentation.
The process removes sand, clay and other substances from the juice. The avoid sucrose decomposition, the juice then passes through a process of pH correction. Once this has been done, the juice is mainly water, mineral salts and sugars.
The juice goes through a boiling process, where moisture is boiled off. The syrup is then cooked so that crystallisation and recuperation of the sucrose can take place. The syrup is placed in large vessels where it is rotated slowly, allowing it to cool evenly. Seeding is then carried out, where small seed crystals are added to the syrup to catalyse the crystallisation process. The molasses separates from the crystals, and the liquid is ready for the next stage.
To complete the process, centrifuging then takes place. During this process the crystallised syrup is separated from the sugar and dried by being put into centrifuges. This produces raw sugar by separating the sugar crystals from the surrounding molasses. For every tonnes of cane that is processed, about 12 tonnes of VHP Very High Polarity sugar is produced and 4 tonnes of molasses. The amount of molasses, which is leftover solution from the sugar processing, that is left on the crystals or added back to the sugar crystals determines what type of sugar is produced.
In addition to white granulated sugar, there are light and dark brown sugars that have a higher molasses content and are often produced for speciality use. Typically at this stage, the sugar is not food grade. Once the sugar has been produced, it is then ready to leave the mill to go to a sugar refinery for further purification, or to a terminal or port, to be delivered directly to an industrial client for use in its raw form. Transportation is done by road, rail or sea.

This, however, would be to use the word in its broadest sense and would encompass technologies discussed in separate papers. For instance, the low natural colour in beet juice makes it possible to produce an acceptable refined sugar in one operation. Similarly it is possible to produce a food grade low colour sugar, often called 'blanco directo', in a cane sugar mill. These notes deal with the production of low colour white sugars from cane, either in a "white end" processing all of the production from a cane sugar factory or in an autonomous refinery.
Before the birth of Jesus of Nazareth, sugarcane from which sugar is made was harvested on the shores of the Bay of Bengal; it spread to the surrounding territories of Malaysia, Indonesia, Indochina, and southern China. The Arabic people introduced "sugar" at that point a sticky paste, semi-crystallized and believed to have medicinal value to the Western world by bringing both the reed and knowledge for its cultivation to Sicily and then Spain in the eighth and ninth centuries. Later, Venice—importing finished sugar from Alexandria—succeeded in establishing a monopoly over this new spice by the fifteenth century; at that point, it started buying raw sugar, and even sugarcane, and treating it in its own refineries.
Sugar is naturally white. When the sugar is initially extracted from the plants, it has a golden color because of the non-sugar materials attached to and within the sugar crystals. This golden sugar is then purified, where these plant fibers and molasses are removed, extracting the sugar molecules from the non-sugar materials and restoring the sugar crystals to their natural white color.
Мы не успеем! - крикнула Соши. - На это уйдет полчаса. К тому времени все уже рухнет. Джабба открыл рот, готовый что-то сказать, но тут его буквально парализовал душераздирающий крик. Все повернули головы к Сьюзан Флетчер, которая выпрямилась и поднялась со стула.
ГЛАВА 36 Ручное отключение. Сьюзан отказывалась что-либо понимать. Она была абсолютно уверена, что не вводила такой команды - во всяком случае, намеренно. Подумала, что, может быть, спутала последовательность нажатия клавиш. Немыслимо, - подумала. Согласно информации, появившейся в окне, команда была подана менее двадцати минут .
Такая работа была непростой, особенно для человека его комплекции. И они делают их все более и более миниатюрными, - подумал. Прикрыв глаза, давая им долгожданный отдых, он вдруг почувствовал, что кто-то тянет его за ногу. - Джабба. Вылезай скорее! - послышался женский голос. Мидж все же его разыскала.
Беккер прикрыл глаза и сжался, раздумывая, сколько времени продлится служба. Выросший в протестантской семье, он всегда считал, что католики ужасно медлительны. Теперь он молил Бога, чтобы священник не торопился, ведь как только служба закончится, он будет вынужден встать, хотя бы для того чтобы пропустить соседей по скамье. А в своем пиджаке он обречен.
Дверь открылась, и коммандер помахал ей рукой. - Спасибо, что пришла, Сьюзан. Я тебе очень благодарен. - Не стоит благодарности.
В обычных условиях такое действие считалось бы недопустимым. Но в сложившейся ситуации никакой опасности в загрузке в ТРАНСТЕКСТ этой программы не было, потому что коммандер точно знал, что это за файл и откуда он появился. - Несмотря на все мое уважение к вам, сэр, - продолжал настаивать Чатрукьян, - мне никогда еще не доводилось слышать о диагностике, в которой использовалась бы мутация… - Коммандер, - перебила его Сьюзан, которая не могла больше ждать. - Мне действительно нужно… На этот раз ее слова прервал резкий звонок мобильного телефона Стратмора. Коммандер поднес его к уху.
