Annual citrus production in Iran is 3.5 million tonnes, which is ranked as sixth in the world.
Before being exported, all citrus fruits are subjected to inspection for quality control purpose and are graded according to their size, maturity, and presence of defect.
The size of a citrus fruit is often represented by its mass because it is relatively simple to measure.
Currently, the measurement is done manually by weighing individual citrus fruits to get a uniform size prior to packaging. However, this manual weighing procedure is time consuming, inefficient, and labor-intensive.
