摘要

Abstract Heating of sugarcane juice gives concentrated sugarcane juice (CSJ) which becomes raw material for the production of a variety of value added products. Conventional ways of CSJ production are environment polluting and indulge in huge amount of energy losses. In this study, an attempt is made to obtain final CSJ (98°B) by induction heating (IH) which is environment friendly and causes minimum energy losses. The experiments are performed at constant heat flux (9947.5 W m−2) on samples of sugarcane juice having 14.2°B, 18.8°B, 23.9°B, and 27.4°B values of initial brix contents. Thermo-enviro-economic analyses are carried out for the experiments conducted on given samples. The results concluded that time required for obtaining final CSJ decreases and evaporation rate increases with increase in initial brix value of sugarcane juice. The energy required for obtaining final CSJ from sugarcane juice of 27.4°B is 683.43 kJ which is 154.3 less as compared to that of fresh sugarcane juice heating with 14.2°B. The environmental parameters have no discernible effects of initial brix value while economic factors were improved. IH is observed thermally and environmentally beneficial with lower costs of CSJ production from the juice of higher initial brix contents.
