The invention relates to a device for optimizing the washing of fruits and similar foods, which comprises a conveyor belt (1) onto which fruit (2) for washing is deposited and includes, above the conveyor belt, at least means (9) for rinsing fruit (2), which are provided with electronically adjustable nozzles (7) operated by a controller (3) configured to generate a frequency signal in proportion to the amount of fruit deposited on the conveyor belt (1) and to apply a proportional volume of water that is based on the fruit deposited on the conveyor belt. The novelty consists in the rinsing means (9) having at least two rinsing pipes (10), each of which has nozzles (7) controlled by the controller (3), such that the rinsing pipes (10) are connected to a common water supply (8) at constant pressure, in order to provide said nozzles (7) with a uniform volume of rinsing water which is proportional to the amount of fruit deposited on the conveyor belt (1).
