Patent ID: 6983848

Claim:
The method of clarifying, in the field, a harvested shaken raw stream of tomatoes of various colors, especially red and green, accompanied by debris and detritus derived from the mechanical separation of tomatoes from their vines, to produce a collection of tomatoes from the raw stream which meet pre-established discrimination criteria and to discard said debris, detritus and tomatoes of which are not within said discrimination criteria said method comprising: a. receiving from the field said shaken raw stream and depositing it on a first conveyor; b. while on said first conveyor, subjecting said raw stream to observation by a first discriminator, said first discriminator having the capability of individually recognizing and removing from said stream a substantial portion of articles which do not comply with said pre-established criteria; c. on said first conveyor, moving said raw stream toward said first discriminator, said discriminator including a plurality of channels of observation of said raw stream, and a plurality of diverters individually adapted on command to physically pass or to divert material in its respective channel, whereby to pass potentially acceptable product to a third conveyor along a first trajectory path, or to deflect unacceptable material to a second conveyor along a second trajectory path, there being a gap between said first and third conveyors through which lighter components of said stream can fall away; d. said third conveyor carrying said potentially acceptable product passed by said first discriminator away from said gap. e. a second discriminator adjacent to said third conveyor including a plurality of channels of observation of the stream passed by said first discriminator, and a plurality of diverters individually adapted on command to physically pass tomatoes which are within said discriminator criteria, or to divert material other than tomatoes, and to pass tomatoes which are within said discriminator criteria to a place of collection.
