Hydro-sorting of apricots based on some physical characteristics

Mirzaee E., Rafiee S., Keyhani A., Emam-Djomeh Z., Kheiralipour K.

In this study, the dropping time of apricot fruits was followed experimentally using a water column. Some effective characteristics of apricots related to the dropping time were determined using standard methods. The best models for the dropping time of Nasiry, Rajabali, and Ghavami apricot varieties as a function of water and fruit densities, shape factor, and fruit volumes were executed with the determination coefficients of 0.95, 0.92, and 0.85, respectively. It was found that the differences between the fruits density minus the density of water had a major effect on their dropping time.
