Transcript of Stalk to Store Sugarcane By Emma Barnett

GROWING
Sugarcane is grown by a sett of cane stalks 40 cm long on flat or gently sloped ground. They are dropped into furrows by machines. Fertilizer is added and they are covered with soil. The sett's need at least 1500 ml of water per year. A few weeks later small shoots appear in the soil. From 1 sett of cane up to 12 stalks can grow.
HARVESTING
The stalks take 12-16 months to grow to their full size of 2-4 metres tall. They are then ready to harvest. They are harvested by self-propelled machines. The machine moves along cutting the stalks off at ground level. The machine then pulls off the leaves and cuts them into smaller lengths called billets. A truck drives along beside the machine and collects the billets until the truck is full. They then have to be transported to the mill.
TRANSPORTATION TO MILL
The sugarcane stalks are then transported to the mill. The truck drives to the closest train station or the sugar is put into another truck and then is taken to the mill. The stalks must be at the mill within 16 hours or all the juice in the stalks will evaporate.
MILLING
When the sugar first arrives at the mill, it is weighed and recorded by an Automatic Cane Receiving Station. The stalks are then washed thoroughly. They are then ready to be chopped and shredded. The stalks are crushed by large rollers to separate the sugar juice from the fibrous material, which is called Bagasse, which is then used to run the mill's boiler furnaces. The sugar juice is then cleaned and thickened into a syrup by boiling off the excess water. The juice is then boiled until it has formed small sugar crystals. The crystals are boiled until they have grown to a bigger, more eatable size. Finally, the crystals are tumble dried and stored in big bins until they are ready to be transported to the Refinery.
TECHNOLOGY

REFINERY
When the sugar crystals first arrive at the refinery, they are washed and dissolved into hot water. Carbon dioxide and lime is added to remove any impurities. The sugar juice is then filtered through a piece of cloth to remove any final colours or remaining impurities. The juice is then boiled in a large vacuum can. The juice again forms fine crystals. When the crystals are large enough, they are tumbled dried to remove any remaining moisture. After this final step, the sugar is finally ready to be delivered to customers.
One of the most important pieces of technology in this process is the Self-Propelled Tractor. This machine is an efficient and much easier way to harvest the sugarcane. It is easily controlled and saves precious time. The sugar is cut off at ground level and the smaller leaves are cut off too. Another tractor drives along beside collecting the cane stalks which are now called billets. This machine also decreases the amount of germs and bugs that can be found on and in the sugarcane stalks.
