Sugar Manufacturing Process :

1. Juice extraction from cane

Juice can be removed from cane either by repeated crushing and washing (milling) or by washing alone, with a final squeezing simply to dry the spent fibre (diffusion). Better sucrose extraction can be obtained by crushing finely shredded cane rather than intact stalks and Preparation refers to that step in which cane is finely shredded before juice is extracted either by milling or diffusion. Cane is prepared by passing it through one or two sets of cane knives and then through a shredder.



2.Milling:

A basic cane mill consists of three grooved rollers. Prepared cane is squeezed between the rollers, thus forcing the juice out of the fibre.

A single milling unit would give an unacceptably low extraction. Typically, five mills are set in tandem and cane is passed in series from Mill 1 to Mill 5.



3.Purification of juice:

Juice from a milling tandem contains a large amount of cane fibre that falls out with the juice between the rollers of the mills. To remove the fibre, juice is poured over a wire-mesh screen, or cascaded over an inclined wedge-wire screen.

The juice is heated and lime is added to neutralise the natural acidity.It is then placed in a large settling tank called a clarifier.The purpose of clarification is to produce a clear juice that is light in colour and free of suspended matter. To improve the precipitate formation, flocculent is added.



4. Crystal growth: Evaporation:

Before crystal growth can take place the clear juice must be concentrated to syrup by the removal of water by evaporation. To improve the efficiency, a process known as multiple effect evaporation is used. Multiple effect evaporation is the scheme where juice is boiled in series in several vessels, with steam fed to vessel 1 only. Vapour from vessel 1 boils the juice in vessel 2, vapour from 2 boils the juice in 3, and so on until vapour from the final vessel goes to waste.

The syrup produced by the evaporators is concentrated further in specially designed vessels known as pans. As the concentration rises the dissolved sugar crystallises and the work of the pans is
