Abstract
Abstract Food piece slices serially formed by the blade of a slicer are captured with a moving stream of liquid and carried in the moving stream of liquid during free-fall of the liquid under the influence of gravity to a moving conveyor belt where the slices are monolayered.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
115 words
A food piece slicing and handling method, comprising: (a) forming an elongate moving curtain of liquid at least a portion of which is free-falling unsupported by a surface and free from surface contact; (b) serially forming separate slices of a food piece by moving the food piece against a sliding blade; (c) capturing a serially formed slice with the moving curtain of liquid so that the slice first contacts the liquid in the free-falling unsupported portion thereof; (d) carrying the slice with the moving curtain of liquid during free-fall of the liquid under influence of gravity to a moving porous conveyor belt; and (e) depositing the slice on the moving conveyor belt with the liquid.
Claim 2
Dependent Claim
115 words
A food piece slicing and handling method, comprising: (a) forming an elongate moving curtain of liquid at least a portion of which is free-falling unsupported by a surface and free from surface contact; (b) serially forming separate slices of a food piece by moving the food piece against a sliding blade; (c) capturing a serially formed slice with the moving curtain of liquid so that the slice first contacts the liquid in the free-falling unsupported portion thereof; (d) carrying the slice with the moving curtain of liquid during free-fall of the liquid under influence of gravity to a moving porous conveyor belt; and (e) depositing the slice on the moving conveyor belt with the liquid.
Claim 3
Dependent Claim
19 words
The method of claim 1 wherein the food piece is an apple and the liquid is an anti-browning solution.
Claim 4
Dependent Claim
13 words
The method of claim 2 wherein the solution is a sodium bisulfite solution.
Claim 5
Dependent Claim
24 words
The method of claim 1 wherein during the capturing step, the moving curtain of liquid initially contacts an underside of a serially formed slice.
Claim 6
Dependent Claim
20 words
The method of claim 1 wherein the moving curtain of liquid exits a linear, longitudinal slot beneath the slicing blade.
Claim 7
Dependent Claim
23 words
The method of claim 5 wherein the food piece is sliced parallel with the longitudinal slot during serial formation of said separate slices.
Claim 8
Dependent Claim
22 words
The method of claim 1 wherein the depositing step includes the step of serially monolayering the slices on the moving conveyor belt.
Claim 9
Independent Claim
182 words
An apparatus for slicing and handling a food piece comprising: a slicing blade; means for moving a food piece against the slicing blade to serially form separate slices of the food piece; means for forming an elongate moving curtain of liquid at least a portion of said curtain is free-falling unsupported by a surface and free from surface contact, including a linear, longitudinal slot positioned beneath the slicing blade; a chamber means for connecting said slot with a source of liquid; baffle means in the chamber for stabilizing flow of liquid through the slot to form a substantially uniform curtain of liquid exiting the slot; and a moving porous conveyor belt on which the slices are deposited and monolayered; wherein the free-falling unsupported portion of the liquid curtain is positioned adjacent the cutting blade so as to capture the serially formed slices such that the slices first contact the liquid in the free-falling unsupported portion thereof, and wherein the slices are carried with the moving curtain of liquid, during free-fall of the liquid under influence of gravity, to said moving conveyor belt.
Claim 10
Independent Claim
182 words
An apparatus for slicing and handling a food piece comprising: a slicing blade; means for moving a food piece against the slicing blade to serially form separate slices of the food piece; means for forming an elongate moving curtain of liquid at least a portion of said curtain is free-falling unsupported by a surface and free from surface contact, including a linear, longitudinal slot positioned beneath the slicing blade; a chamber means for connecting said slot with a source of liquid; baffle means in the chamber for stabilizing flow of liquid through the slot to form a substantially uniform curtain of liquid exiting the slot; and a moving porous conveyor belt on which the slices are deposited and monolayered; wherein the free-falling unsupported portion of the liquid curtain is positioned adjacent the cutting blade so as to capture the serially formed slices such that the slices first contact the liquid in the free-falling unsupported portion thereof, and wherein the slices are carried with the moving curtain of liquid, during free-fall of the liquid under influence of gravity, to said moving conveyor belt.
Claim 11
Dependent Claim
94 words
The apparatus of claim 8 further including a liquid distribution manifold connecting the chamber with a liquid source, wherein the baffle means comprise a first barrier portion between the manifold and the slot, the first barrier portion extending upwardly from a floor portion of the chamber but not contacting a ceiling portion of the chamber, the baffle means further comprising a second barrier portion between the first barrier portion and the slot, the second barrier portion extending downwardly from the ceiling portion of the chamber but not contacting the floor portion of the chamber.
Claim 12
Dependent Claim
24 words
The apparatus of claim 9 wherein the baffled chamber further includes a ramp portion extending between the floor of the chamber and said slot.
