Study of Jaggery processing plant to improve the themal performance

Jaggery industry is one of the most important cottage industries in India. Jaggery is prepared mostly by small and marginal farmers. The production process of jaggery involves crushing of cane, boiling and concentration of juice, moulding into the standard shapes and sizes and packaging in suitable packages. The thermal performance of jaggery processing plant will be improved by parameters like design of furnace, drying process of jaggery, freez concentration of sugarcane juice, heat transfer and mass transfer from sugarcane juice for evaporation, moisture content of bagasse. In this review paper focus is on the effect of number of boiling pans used in design of furnace, and several methods used in available literatures are discussed. The improved plant and the conventional plant are compared on the basis of four parameters viz. jaggery production, baggase consumption, emissions and temperature of exhaust.
