Abstract

A process for sorting bulbous and tuberous produce according to successive size classes, in particular suitable for sorting potatoes, whereby in the transitional range between at least two successive main classes at least one intermediate class is defined; a first sorting operation is carried out, in which produce is sorted according to sizes falling within the remaining range of the at least two main classes and the at least one intermediate class; the produce selected as falling within the remaining range of the main classes are passed to collections of produce belonging to those main classes; the produce falling within the at least one intermediate class is subjected to a second sorting operation (4,5), the produce falling into an intermediate class being separated into a first group belonging to the one main class pertaining to the relevant intermediate class and a second group belonging to the other main class pertaining to the relevant intermediate class; and the two groups are added to the collections belonging to the main classes. <IMAGE>
