Modeling of Dropping Time of Kiwi Fruit in Water

In this study, the dropping time of Hayward kiwi fruit was theoretically formulated and then determined experimentally using water column. Some effective characters of kiwi fruit on rising time were determined using standard methods. The best model for dropping time of Hayward kiwi fruit was found as: with R 2 = 0.96. The difference of fruit density minus the density of water and volumes of fruit had major effect on dropping time of kiwi fruit. The fruit shape had only a small effect on it. It was concluded that on online sorting system; dropping time has potential to remove poor quality fruit from kiwi fruit.
