Abstract

Abstract The present apparatus relates to cleaning means for a roller conveyor employed in a fruit and vegetable peeling operation, for example, in the peeling of white potatoes employing a lye treatment followed by the application of infrared radiant heat. The rollers which carry and turn the potatoes under the infrared rays become coated with a paste-like substance as the infrared rays take effect in conditioning the activating lye and conditioning the skin for removal, and these rolls are subjected to a cleaning operation by blade means.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 150 words
In a peeling machine, a roller conveyor for traveling through a treating zone to carry products to be treated therein, said roller conveyor comprising a plurality of rollers and having a return stretch; a track for controlling the travel of the roller conveyor and predetermining the path of the rollers comprising said return stretch during their travel through a cleaning zone; rotary blades mounted for rotation in a path parallel to and closely adjacent one stretch of said roller conveyor, said blades moving in closely spaced relation with respect to said rollers during travel through said cleaning zone for effecting removal of excess material adhering thereto; a sprocket provided at one end of each roller, the sprockets on adjacent rollers alternating from end to end; and, a pair of fixed chains mounted on said machine so as to be engaged by said sprockets during their travel through the cleaning zone.
Claim 2
Dependent Claim 150 words
In a peeling machine, a roller conveyor for traveling through a treating zone to carry products to be treated therein, said roller conveyor comprising a plurality of rollers and having a return stretch; a track for controlling the travel of the roller conveyor and predetermining the path of the rollers comprising said return stretch during their travel through a cleaning zone; rotary blades mounted for rotation in a path parallel to and closely adjacent one stretch of said roller conveyor, said blades moving in closely spaced relation with respect to said rollers during travel through said cleaning zone for effecting removal of excess material adhering thereto; a sprocket provided at one end of each roller, the sprockets on adjacent rollers alternating from end to end; and, a pair of fixed chains mounted on said machine so as to be engaged by said sprockets during their travel through the cleaning zone.
Claim 3
Dependent Claim 106 words
In a peeling machine, a roller conveyor for traveling through a treating zone to carry products to be treated therein, said roller conveyor comprising a plurality of rollers and having a return stretch; means defining an arcuate path for the rollers of said roller conveyor comprising said return stretch during their travel through a cleaning zone, horizontal blades mounted for rotation about an axis and through a cylindrical path corresponding to a portion of the arcuate path of said rollers, said blades moving in closely spaced relation with respect to said rollers during travel through said cleaning zone for effecting removal of excess material adhering thereto.
Claim 4
Dependent Claim 106 words
In a peeling machine, a roller conveyor for traveling through a treating zone to carry products to be treated therein, said roller conveyor comprising a plurality of rollers and having a return stretch; means defining an arcuate path for the rollers of said roller conveyor comprising said return stretch during their travel through a cleaning zone, horizontal blades mounted for rotation about an axis and through a cylindrical path corresponding to a portion of the arcuate path of said rollers, said blades moving in closely spaced relation with respect to said rollers during travel through said cleaning zone for effecting removal of excess material adhering thereto.
Claim 5
Dependent Claim 70 words
In a peeling machine as recited in claim 2, in which said rollers of said conveyor are each provided with a sprocket at one end thereof, the sprockets on adjacent rollers alternating in their end position, and in which two fixed chains are mounted for engagement, respectively, by the sprockets at the ends of said rollers, and in which the mounting means for said chains predetermines an arcuate shape thereof.
Claim 6
Dependent Claim 154 words
In a roller conveyor for traveling through a treating zone to carry products to be treated therein, said roller conveyor having a return stretch, the improvement comprising: means for predetermining the path of the rollers comprising said return stretch during their travel through a cleaning zone, means for rotating the rollers about their axes as the rollers travel through the cleaning zone, blades mounted beneath said return stretch for rotation about an axis extending generally normal to the rollers of the conveyor in the cleaning zone, said blades moving about said axis in a planar path beneath and adjacent to the bottom of said rollers during travel through said cleaning zone for effecting removal of material adhering thereto, and an open ended housing mounted in the cleaning zone to extend from closely adjacent the rollers downwardly in circumscribing relationship to the blades so that material removed from the rollers is contained and guided downwardly.
Claim 7
Dependent Claim 154 words
In a roller conveyor for traveling through a treating zone to carry products to be treated therein, said roller conveyor having a return stretch, the improvement comprising: means for predetermining the path of the rollers comprising said return stretch during their travel through a cleaning zone, means for rotating the rollers about their axes as the rollers travel through the cleaning zone, blades mounted beneath said return stretch for rotation about an axis extending generally normal to the rollers of the conveyor in the cleaning zone, said blades moving about said axis in a planar path beneath and adjacent to the bottom of said rollers during travel through said cleaning zone for effecting removal of material adhering thereto, and an open ended housing mounted in the cleaning zone to extend from closely adjacent the rollers downwardly in circumscribing relationship to the blades so that material removed from the rollers is contained and guided downwardly.
Claim 8
Dependent Claim 26 words
In a roller conveyor, as recited in claim 4, the improvement wherein the blades extend radially from the axis at angularly spaceD intervals from one another.
