JAGGERY PROCESSING
|
HARVESTING |
|
Sugar cane is harvested by mechanical harvester, chopping the stems and leavening the roots. Then, cut the stalks into short pieces known as billets. Billets are loaded into bins and transport to sugar mills. |
|
WASHING |
|
Sugar cane arrived and washed to remove excess soil and rocks. Cane is cleaned by flooding the carrier with warm water and sprayed by placing on agitating conveyers. |
|
CRUSHING |
|
First step in jaggery manufacturing operation is the weighing of cane and then transferred to crusher to extract the juice from cane stalks. |
|
JUICE STORAGE TANK |
|
Crushed juice is stored in storage tank and the pH at this stage is 5.2-5.3 and store for 2-3 hrs. Clarification process is done in this tank to remove impurities. The addition of lime in this tank improve the consistency of jaggery by increasing crystallization of sucrose. |
|
CHURNING |
|
The juice from storage tank fed to the churner, where further impurities are removed. The pH of the juice in churner is around 5.8-6.0. Mucilage of okra is added as flocculent, which interrupts dirt and forms colloid suspension. |
|
JUICE BOILING |
|
The juice pH in the boiling stage is 5.5. Juice is heated and stirred in large big pan at 105-106 0C |
|
COOLING |
CHURNING |
|
Liquid syrup is allowed to cool down at room temperature then stored in large barrels for 72 hrs. |
Juice is again heated in the churner and boiled for evaporation At this stage, the temperature is 118-1200C |
|
BOILING |
COOLING |
|
Slight heated the juice and add citric acid, benzoic acid and potassium metabisulphite as preservative. |
The juice is immediately removed and cooled with constant stirring. As temperature falls, jaggery begins to crystallize. |
|
FILLING |
MOULDING |
|
The liquid is then poured and packaged in air tight bottle and
container. |
After 30-40 min, semi-solid jaggery is put in galvanized moulds and
then separate it form and wrapped in plastic and store in cool and dry place. |
