In-feed mixing is essentially a mechanical process where there is both a re-sequencing of fruit order and delays due to traps to fruit flow. It is possible to consider the in-feed system as a continuous sequential stream of fruit. However, this is not strictly true as the fruit stream is normally split across sorting tables and then rejoined after any reject fruit have been removed. However, provided conveyor speeds and sorting table lengths are consistent, as was the case in the packhouse used, this assumption is justified.
