ABSTRACT = {Non-centrifugal cane sugar (NCS), known as Jaggery, is a form of unre-
fined sugar which contains molasses. The integration of renewable energy
resources in the production of NCS, have been analysed. The work investigates
the energy requirements of a system incorporating a freeze-concentrator and a
solar thermal heater to reduce the reliance on the combustion of bagasse or other
fuels in a Jaggery production process. Depending on the extent to which freeze concentration can be incorporated into the process, results show that the minimum theoretical energy required to produce Jaggery can be reduced by 91.30% overall.
Although difficult in practice, this theoretical analysis demonstrates that the integration of freeze concentration close to the eutectic limit of concentration has significant
advantages. For optimal configuration and ideal operation of the system the analysis
reports a requirement of approximately 3.8 MJ to produce a kilogram of Jaggery
from cane juice. When typical process efficiencies (furnace, boiling pan, solar thermal collector, and chiller) are included, the energy required ranged from 4.8–5.2 MJ/
kg Jaggery. This represents a potential energy saving in excess of 38 MJ/kg Jaggery
and a fuel saving of more than 2 kg of bagasse/kg of Jaggery produced.},
