dc.description.abstractThe present study was conducted to design and develop solar hybrid essential oil extraction system at Department of Processing and Food Engineering, PAU, Ludhiana. The conceptual design of the solar hybrid essential oil extraction system was done for essential oil extraction from turmeric. The system was designed in such a way that it will extract oil from a batch of about 10 kg of raw material. The volume of the distillation unit has a capacity of 0.061m3, the steam generation unit has a capacity of 0.057m3 and the condensing unit has a capacity of 40.50%. The smallest grates size (14.50mm) has the highest oil yield as compared to the largest grates size (17.53mm). The extracted essential oil was evaluated qualitatively in terms of refractive index, specific gravity color, saponification value, acid value, and ester values. The range of various chemical properties are specific gravity (0.89-0.93), refractive index (1.52-1.55), saponification value (35.21-38.13mg KOH/g), ester value (3.59-5.56mg KOH/g), acid values (31.61-32.59mg KOH/g) and colour values are L (32.70-38.90), a (-1 to -5.60) and b (10.6-19.40). The benefit-cost ratio was computed as 1.13 and break-even point for solar hybrid essential oil extraction system can be achieved after 1.85 years. The developed solar hybrid essential oil extraction reduces the extraction time (11.50%), energy consumption (11.75%) and can produce good quality essential oil which is free from wax. This environment friendly developed system lower operating and maintenance costs. The further analysis of the total extraction time and less energy consumption may help in designing a suitable solar hybrid essential oil extraction system with proper control of its operating parameters, and optimization of the process.en_US
