①Pressing

Sugarcane crushed, using the method of pressing the juice from the cane, the juice into the next process, get bagasse, bagasse, most of them into the boiler combustion, generating steam to drive the turbine to generate electricity, for the whole plant production;

②Clarification

Pressing out of the cane juice to add lime and through the SO2 clarification, while adding phosphoric acid and flocculant, to generate CaSO3 precipitation, separated by the settling tank, to get the clear juice, the clear juice into the next process, the clear juice into the settling tank separation, to get the CaSO3 precipitation, the clear juice, the clear juice into the settling tank, to get the clear juice. SO2 for clarification, while adding phosphoric acid and flocculant to generate CaSO3 precipitation, separated by the settling tank, to get the clear juice, clear juice into the next process, the resulting precipitation after filtration, to get the sludge;

③ evaporation

clear juice by heating, which will evaporate the water for concentration, the use of five-effect evaporation, and finally in the vacuum decompression to get the sugar syrup, syrup After floating treatment or sulfur fumigation and decolorization, the syrup is processed into the next process;

4 Cooking sugar

Syrup in vacuum conditions, further heating and concentration, to get a supersaturated concentrated solution containing white sugar crystals, after aiding crystal, honey, drying, sieving to get the finished product of white granulated sugar.

2, sugar beet sugar

① Sugar beet pretreatment and exudation

Take wet conveying as an example. Sugar beets are washed in the washer after removing soil, grass and stones. After washing, the beets go through the shredder, and the shredded beets go into the continuous exuder. The oozing sugar juice is sent to the next section after dregs removal and heating.

②Cleaning

The cleaning process includes two parts: ash filling and sulfur bleaching.

a) Add ash full filling: double carbonate method. Ash cleaning includes two main processes, the first process for the addition of ash and a carbon saturated, add lime and pass into the sugar juice for carbonic acid saturated, remove impurities, saturated carbon juice after filtration, filter sludge as solid waste collection; the second process for the two carbon saturated, filtered juice into the two carbon saturated canisters for the second saturated, pass CO2 so that the excess of the lime in the sugar juice to further precipitation and separation of the two carbon juice after filtration, filtered juice into the next step of the sulfur bleaching process. The second carbon juice is filtered and the filtered clear juice goes into the next step of sulfur bleaching process, and the filtered mud is collected as solid waste.

b) sulfur bleaching: the main purpose of sulfur bleaching is to reduce the color of sugar juice. Sugar juice quickly into the sulfur bleaching device to generate negative pressure, will be cooled SO2 gas inhalation, and in the pipeline and the sugar juice is fully mixed, and quickly complete the absorption of SO2 gas, SO2 gas into the sugar juice is first dissolved in water into a strong reducing sulfurous acid, and then organic pigments into colorless compounds, decolorization of sugar juice. The decolorized sugar juice is filtered and sent to the evaporation process.

3 evaporation

Sugar evaporation generally uses four or five effect evaporation system. After evaporation to remove the water, sugar juice is concentrated into syrup.

4 Cooking sugar

Syrup in the vacuum conditions, further heating and concentration, to get a supersaturated concentrated solution containing white sugar crystals, by the crystal, honey, drying, sieving to get the finished product of white sugar.
