Abstract
Abstract An apparatus for preparing folded food chips includes means for sheeting dough and for cutting successive disk-shaped segments from the sheeted dough. These segments are deposited on the upper pass of a conveyor chain such that the chain generally bisects the segments. Consequently, the sides of the segments drape downwardly and the segments assume a folded configuration. The sheeted dough remaining after the disk-shaped segments have been deposited drops to the sides of the chain and is returned to be again sheeted and cut. The upper pass of the chain rides on guide plates which prevent the dough segments from curling beneath the chain. The chain extends into an oven and by the time the folded segments reach the discharge end of the conveyor chain enough moisture has been removed from the folded segments to enable them to remain in the folded configuration without support from the chain. An air jet issuing from a nozzle adjacent to the discharge end of the conveyor chain dislodges the folded segments from the upper pass of the chain, and the folded segments so dislodged fall onto accumulating conveyor means which is also disposed in the oven. While on the accumulating conveyor means the segments are turned over. The accumulating conveyor means deposits the folded segments onto cooling conveyor means where they are cooled, and the cooling conveyor means delivers the cooled segments to a fryer. The food chips emerge from the fryer.

Claim 4
Independent Claim
111 words
An apparatus for preparing folded food chips from dough, said apparatus comprising: means for forming the dough into diskshaped segments, an endless shaping conveyor having a conveying pass which is narrower than the disk-shaped segments and on which the disk-shaped segments are deposited and supported with the conveying pass generally bisecting the segments, whereby the sides of the disk-shaped segments drape downwardly and the segments assume a folded configuration; means disposed beneath the conveying pass of the shaping conveyor for preventing the sides of the folded segments from curling under the conveying pass; and means for heating the folded segments when they are on the shaping conveyor to remove moisture therefrom.
Claim 5
Dependent Claim
42 words
An apparatus according to claim 1 wherein the means for heating the folded segments removes enough moisture from the segments while the segments are on the shaping conveyor to enable the segments to maintain their folded configuration after leAving the shaping conveyor.
Claim 6
Dependent Claim
42 words
An apparatus according to claim 2 wherein the means for preventing the folded segments from curling under the conveying pass is a guide plate disposed beneath the conveying pass and having generally flat side faces which are oriented in a vertical disposition.
Claim 7
Dependent Claim
19 words
An apparatus according to claim 3 wherein the conveying pass rides on and is supported by the guide plate.
Claim 8
Dependent Claim
24 words
An apparatus according to claim 2 and further characterized by accumulating conveyor means located beyond the shaping conveyor and receiving the folded chips therefrom.
Claim 9
Dependent Claim
40 words
An apparatus according to claim 5 and further characterized by air nozzles positioned adjacent to the discharge ends of the shaping conveyor for directing a stream of high velocity air toward the shaping conveyor to dislodge the folded segments therefrom.
Claim 10
Dependent Claim
25 words
An apparatus according to claim 6 wherein the means for heating the segments also heats the segments while they are on the accumulating conveyor means.
Claim 11
Dependent Claim
58 words
An apparatus according to claim 5 and further characterized by cooling conveyor means located beyond the accumulating conveyor means for receiving the folded segments discharged from the accumulating conveyor means, the cooling conveyor means being outside the means for heating the golded segments so that the temperature of the folded segments decreases while on the cooling conveyor means.
Claim 12
Dependent Claim
61 words
An apparatus according to claim 8 wherein the accumulating conveyor means comprises a pair of belt-type endless conveyors with one being located after the other, the discharge end of the first conveyor being located above the receiving end of the second conveyor so that the folded segments turn over as they are transferred from the first conveyor to the second conveyor.
