Abstract
Abstract A patty cooker particularly for use in finishing precooked meat patties having a predetermined transverse dimension has a frame on which a conveyor made up of rather widely spaced, small diameter cross bars advances in a predetermined direction. A nozzle or preferably a plurality of nozzles having outlet openings elongated in the direction of conveyor advance are arranged side by side transversely of the conveyor and close to the patty. A jet of hot air issues from each nozzle and impinges upon the patty in a restricted area. The jets leave untouched zones between such areas. The effect is to provide browned or seared marks or parallel stripes on the patty like grill marks. Preferably nozzles are arranged above and below the conveyor and directed toward the patty from opposite directions, simultaneously to provide sear marks both top and bottom.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
A patty finishing cooker for a patty of a predetermined transverse dimension comprising a frame, a conveyor, means for supporting and advancing said conveyor on said frame in a predetermined direction, a nozzle having an elongated outlet opening of a width substantially less than said predetermined transverse dimension, means for mounting said nozzle on said frame with said nozzle directed toward said conveyor and with said elongated outlet substantially parallel to said predetermined direction, and means for discharging a jet of hot air from said outlet toward and against a transversely narrow portion of said patty only and away from parts of said patty on either transverse side of said portion.
Claim 2
Dependent Claim
111 words
A patty finishing cooker for a patty of a predetermined transverse dimension comprising a frame, a conveyor, means for supporting and advancing said conveyor on said frame in a predetermined direction, a nozzle having an elongated outlet opening of a width substantially less than said predetermined transverse dimension, means for mounting said nozzle on said frame with said nozzle directed toward said conveyor and with said elongated outlet substantially parallel to said predetermined direction, and means for discharging a jet of hot air from said outlet toward and against a transversely narrow portion of said patty only and away from parts of said patty on either transverse side of said portion.
Claim 3
Dependent Claim
30 words
A device as in claim 1 including means for heating said jet of hot air to a temperature sufficient to sear said transversely narrow portion only of said meat patty.
Claim 4
Dependent Claim
49 words
A device as in claim 1 in which said outlet is of a transversely narrow dimension, and means for mounting said outlet close enough to a patty on said conveyor to direct said jet of hot air onto an area of said patty of only said transversely narrow dimension.
Claim 5
Dependent Claim
68 words
A device as in claim 1 including a plurality of said nozzles, and means for supporting said nozzles in an arrangement with the outlets thereof spaced apart transversely of said conveyor at distances apart to separate the area of impingement of each of said jets on said patty from the impingement areas of adjacent ones of said jets and to leave unimpinged spaces between said areas of impingement.
Claim 6
Dependent Claim
21 words
A device as in claim 1 including means for disposing said elongated nozzle outlet out of parallelism with said predetermined direction.
Claim 7
Dependent Claim
84 words
A device as in claim 1 in which said nozzle has an inlet portion spaced away from said conveyor and having a transverse dimension substantially equal to a predetermined fraction only of the transverse width of a patty on said conveyor, and has a discharge portion adjacent said conveyor of a predetermined width substantially less than said transverse dimension whereby said nozzle tapers transversely from said inlet portion to said discharge portion substantially to confine discharge from said discharge portion to said predetermined width.
