  1. How is sugar obtained commercially? Wang Si Zhe 1o226

  2. Uses of sugar • Obtaining of sugar • Separation techniques used • Diagram on separation techniques • Bibliography Table of content

  3. Sugar is required for many uses some are: • Cooking ingredients • Sports and soft drinks • A source of alcohol • Fuelling car-(sugar-based ethanol) Uses of sugar

  4. Sucrose or table sugar is an organic compound. • Its molecular formula isC12H22O1 • Our sugar is extracted from nature, sugar canes and sugar beets. Basic introduction of sugar

  5. It is then taken to industries to extract the sugar. • Firstly, it undergoes affination. • After, the syrup-sugar mixture will be centrifuged to separate the sugar from the syrup. • Then it is mixed with hot, sweet water. • Secondly, it goes through a process known as carbonatation or sometimes, phosphatation. • Then it is filtered to remove the chalk and the non-sugars. How is sugar obtained commercially?

  6. Thirdly, it undergoes decolourisation to remove colour. • Lastly, it undergoes crystallisationto obtain the pure sugar crystals. • For maximum sugar production, the waste is crystallized again until there is no more sugar can be obtained. How is sugar obtained commercially

  8. Filtration • Crystallisation • Centrifuge Separation techniques

  9. Filtration is used the separate colloids from a suspension. • The suspension passes through a filter and the colloid which is left behind is known as the residue. • The liquid which collected is the filtrate. What is filtration

  10. After the affination process, the sugar went through carbonatation, the calcium carbonate collected lots of non-sugars. • The suspension passes through a filter and chalk with the non-sugars are removed. Filtration in removal of sugar

  11. Water taps have a small filter to remove large mineral deposits. • Coffee makers used filtration to keep coffee grounds out of water. • Air-conditioners used filtration to remove dust particles. Filtration in other uses

  12. Crystallisation is the process in which to extract solute from solvent and also to purify the substance. • It is used to remove easily-decomposed solute from solvent. Crystallisation

  13. Heat the solution and evaporate most of the solvent. • Allow the solution to cool and it will form a saturated solution. • Crystals will start to grow. • Remove the crystals through filtration and dry it by putting it between two filter papers. Steps to do crystallisation

  14. The liquor which contains the sugar is boiled and then cooled, forming sucrose. • The sucrose is removed through centrifuge . • The liquor still undergoes crystallisation to extract more sugar. This process is called recovery. Crystallisation in removing sugar

  15. Centrifuge is a machine which separates lighter particles from denser particles. • The mixture in the centrifuge spins very quickly and separates the particles. Centrifuge

  16. In the mother liquor, it is spun in a centrifuge which removes sucrose from the liquor. • The liquor is spun as much as possible until there is no deposits of sucrose and the liquor is rejected as molasses. Centrifuge in the process of making sugar

  17. Centrifuge is used in separating: • Red blood cells from blood. • Oil industries. Centrifuge in other uses
