ABSTRACT:

BACKGROUND OF THE INVENTION
This invention relates to apparatus and methods for washing the cored area of a lettuce head.
The field to which the invention relates is that of agricultural equipment and methods used in harvesting operations.
BRIEF SUMMARY OF THE INVENTION
The invention is an apparatus and method for washing a plurality of cored lettuce heads as they are harvested in the field. The apparatus comprises a conveyer forming a loop, support platforms attached to the conveyer with at least one lettuce head guide connected to each support platform, and an aqueous solution spraying system fixedly attached at a point along said conveyer loop. The claimed method involves the steps of placing at least one cored lettuce head onto a conveyer, conveying the lettuce head(s) to an aqueous solution spraying system, delivering an aqueous solution into the core hole(s) of the lettuce head(s) for a time and at a pressure sufficient to wash the core hole(s), and removing the cored lettuce head(s) from the conveyer.
