Dry cleaning is the preferred method as it is more environmentally friendly and does not affect the TRS content. After 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 cane sugar is not food grade. When the sugar has been produced from the sugar cane, it is then ready to leave the mill. Some of the sugar will be sold to a sugar refinery for further purification, which through another set of processes turns raw sugar into refined sugar.
You can read more about this in our blog on refined sugar production. This is a common route of travel for raw sugar, as many types of food and beverages, most notably confectionary, use refined sugar in their recipes. Refined sugar can be made from either cane sugar, which we have covered in this blog, or beet sugar, which you can find out about in this blog. There is also a large global raw sugar market.
Any cane sugar destined for this route will be taken from the sugar mill to a terminal or port, to be delivered directly to an industrial client for use in its products. Under a traditional FOB Free On Board contract , it is the obligation of the seller to organise transport of the raw sugar from the mill to where it is required, often involving long journeys by truck, rail and ship.
Normally the sugar would need to travel to a port, where it would then be loaded onto a bulk freight ship chosen by the buyer. However, increasingly at Czarnikow we are working to buy sugar directly from producers at their factory gates, so that we can pay them quickly and take on the logistical responsibility on behalf of our clients from that point, enabling us to offer a holistic supply chain service.

February 21, We break down the production of sugar cane into 6 key steps: 1. Refined Cane Sugar How to grow sugar cane Sugar cane is grown in warm to tropical areas of the world, with Brazil, India, Thailand, China and Australia as the leading global producers of sugar cane.
Harvesting Sugar Cane Cane sugar does not need to be re-planted, as only the top of the plant is removed during harvest. Get your free 5 year sugar market forecast.

Monitoring of equipment and filtering materials ensures that they are working efficiently. Ronald started farming when he was 16 and in his years of experience has figured out the sugar cane planting system that works best, when the weather is agreeable.
Get Social with MoreToSugar. Sugar What Is Sugar? Sugar cane stalks are harvested from fields in locations such as Florida, Louisiana and Texas and then sent to a nearby sugar mill. At the sugar mill, the sugar cane stalks are washed and cut into shreds. Huge rollers press sugar cane juice out of the shredded stalks. The juice is then clarified, concentrated and crystalized. The crystals are spun in a centrifuge to remove the liquid and produce golden raw sugar.
Raw sugar is transported to a cane sugar refinery, where it will be further purified. The raw sugar is melted and filtered to remove remaining impurities primarily molasses. Sugar is packaged and shipped to grocery stores and food manufacturers.
