In this paper, energy and exergy analyses are presented for processing of frozen cherry for a factory in Turkey. Data were collected from each. of the defined basic unit operations: weighing and loading, pre washing, removing the stalks, separating the seeds, inspection and sorting, IQF freezing and packaging. The average energy intensity for processing a batch of 146 tonnes cherry to 99.28 tonnes of frozen cherry was estimated as 0.4 MJ/kg. The types of energy used in the manufacturing of frozen cherry were electrical and manual with the respective proportion of 99.78 % and 3.22 % of the total energy. The most energy consumed unit was IQF Freezing, followed by inspection & sorting which accounted for about 87.59 % and 5.67 % of the total energy input, respectively. Weighing and loading unit consumed the least energy, which is about 0.03 % of the total energy input. The exergy analysis revealed that the IQF freezing operation was responsible for most of the inefficiency (66.89 %) followed by separating the seeds operation (11.48 %).
