***********************************

Manufacturing Process : Sugar Plant

 

The process of manufacturing process:

 

1. Extraction of juice (Crushing)

2. Clarification of juice

3. Concentration of juice (juice to syrup) by evaporation

4. Boiling of Syrup to grain (crystallization)

5. Separation of crystals from mother liquor (Centrifuging)

 

Cane receiving

Sugarcane Weighment

 

Sugarcane Unloading:  The cart cane will be manually unloaded directly to the cane carrier.

The cane from the trucks and tractor- trailers will be unloaded with the help of cane un-loader crane. The cane will be unloaded on to the feeder table.

 

Sugarcane Conveying:

The cane from the feeder table will be  then dumped to the main cane carrier, which conveys the cane to the cane preparatory devices.

Electronic devices, depending on the cane-crushing

rate control the speed of the cane carrier, and level in the cane carrier etc.

 

Sugarcane preparation:

The sugar cane will be passed through the cane preparatory devices called leveller, cutter and fibriser where in the cane is cut into small pieces to expose the juice cells for extraction. The preparatory index is about 85-90 %.

 

Milling:

Sugarcane from the fields are weighed and fed in cane carrier by means of cane unloaders. The cane is passed through kicker, leveler and Fibrizer. The Fibrizer improves the extraction of the mills by breaking the rigid ness of the cane and so facilitating its disintegration and extraction of its juice.

The fibres are then crushed in mill house, consisting of the 4 mills. During crushing, juices present in the cane cells are extracted by the mills. The juice obtained from milling is sent for process, fibre that comes out from 4thmill is termed as bagasse and it is used as fuel in boilers.

 

Clarification:

The extracted juice from mills is called as raw juice and it is heated to 70  – 75 Deg. C. in juice heaters and treated simultaneously with the milk of lime and sulphur dioxide gas in order to separate the impurities. The sulphited juice is again heated to 102 Deg. C through juice heaters and allowed to settle in the clarifier. The purified juice, which comes out from clarifier, is called as clear juice and is sent to evaporator for concentration. The settled impurities are called mud. The mud contains small amount of juice, which is separated in vacuum filters.

 

Crystallisation:

The sulphited syrup is concentrated further in the vessels called pans. During the above process, sugar crystals are developed by means of exhaustion. The formed crystals are then cooled in crystallisers. The crystals are surrounded by thin film liquid called as mother liquor. The crystal  along with the mother liquor (Molasses) is called as massecuite.

 

Curing:

The above massecuites are centrifuged in centrifugals, where crystals are separated from the mother liquor. Separated mother liquor of massecuites is again used for boiling and maximum exhausted mother liquor is called as Final Molasses, which is stored in the steel tanks and sent to distillery for manufacture of Ethyl alcohol. The separated sugar crystals are dried in hopper, sieved in graders and bagged.

 

***********************************

Conveyors.

Cush - Cush conveyor :

Double scroll type 

The bagasse conveyor also has return conveyor to feed the stored bagasse

Screens : Rotary screen .

will  filter the extracted juice and filtered juice is pumped for further processing. The fibrous residue after juice extraction known as bagasse will be withdrawn from the last mill and conveyed through drag type steel conveyors to boiler for steam generation. Surplus bagasse will be withdrawn from the conveyor and stored for reuse when necessary.

 

DISTILLERYAlcohol Manufacturing  Process

1. Dilution - Preparation of molasses for fermentation

2. Fermentation - Production of alcohol from fermentable

    sugars in molasses solution

3. Distillation - Product Recover

===============================

Distillery Plant : 

To handle the spent wash generated from the distillery plant, incineration boiler will be installed. 

In this boiler 80% of concentrated spent wash and 20% of coal will be used as fuel.


The incineration boiler will have following specification:

Boiler pressure – 45 kg/cm2

Steam flow      – 28 TPH

Steam temp     – 465 C 


Steam Balance for Distillery

Total steam generation – 28 TPH

Steam required for distillery and evaporator – 25 TPH

Steam to auxiliaries – 3 TPH


Power balance for Distillery

Total power generated from Distillery Turbine – 3 MW

Power required for distillery – 1.4 MW

Power required for boiler auxiliaries – 0.4 MW

Surplus power available for export – 1.2 MW

================================

  

All the Conveyors will be covered with GI sheets to prevent the fugitive dust emission into the atmosphere.
