Our main business area is the production of refined cane sugar and sugar by-products. We believe in diversification through setting up new manufacturing facilities and equity participation. The manufacturing process of sugar and its by-products is as follow:
Sugar obtained from sugarcane contains 99.5 percent sucrose, commonly known as cane sugar. Sucrose belongs to a group of carbohydrates called disaccharides. It is soluble in water, slightly soluble in alcohol and ether, crystallises in long, slender needles, and is dextrorotatory. Upon hydrolysis, sucrose yields a mixture of glucose and fructose, which are levorotatory. The mixture obtained is known as invert sugar, and the process is known as inversion. Inversion is carried on in the human intestine through the aid of enzymes known as invertase and sucrase. When heated to temperatures above 180 ° C (356° F), sucrose becomes the amorphous, brown, syrupy substance called caramel.
Sugar is not only used as a constituent in industrial and home made food, but also as raw material in fermentation to produce ethyl alcohol, butyl alcohol, glycerine and citric acid.
Sugar is also an ingredient in transparent soaps and can be converted to esters which yield tough, insoluble and infusible resins.
Sugarcane bagasse is the residue of the crushing and milling of sugarcane. It contains 50 percent moisture and 2 percent sugar in addition to fibre. Bagasse is used as a raw material by the paper industry.
It is commonly used as fuel in boilers in the sugar factory for power co-generation.
Bagasse and wood fibre are used for making building boards by a process similar to paper making.
Molasses, also known as treacle, is a dark brown viscous liquid obtained as a by-product in the processing of cane sugar.
It contains nearly 45 percent uncrystallised, fermentable sugar and some sucrose and is a valued by-product of the sugar industry.
Molasses is used in producing ethyl alcohol, liquor, table syrup and food flavourants. It is also used as food for farm animals and in manufacturing several processed tobaccos.
It can be boiled again to crystallise out some of the rich sucrose content of the liquid. This, however, is not economical.
Pressmud, commonly known as filter cake, is used as manure by farmers. It is combustible and used in kilns for brick making.
When mixed with the spent wash generated by distilleries, the resultant product is enriched organic manure, which has the capability of improving farm yield. It also lessens the need to treat the distillery effluent, which is very toxic and high in BOD and COD contents.
