## Abstract

A method for cold peeling citrus fruit is disclosed wherein the fruit is first cored and sliced into a plurality of segments and the pulp is thereafter severed from the peel by forcing the segment through a knife. An apparatus is disclosed where the fruit segment is secured and compressed on a concave rotary carrier which is then rotated through a concave severing knife which severs the peel and albedo from the pulp.

## Claims

### Claim 1

A method for removing the peel and albedo from the pulp of citrus fruit comprising the steps of:
coring the fruit;
slicing the fruit into twelve uniform segments;
placing the fruit segments in a conveyor to laterally transport individual fruit segments;
sensing the position of a concave rotary carrier;
pushing the fruit segment into the concave rotary carrier when the rotary carrier is at a predetermined loading position;
confining the fruit segment to a radial position on the concave rotary carrier;
forcing the fruit segment substantially towards the center of the concave rotary carrier so that the peel of the fruit is molded against the concave surface of the concave rotary carrier;
rotating the rotary carrier;
forcing the fruit segment through a pointed concave severing knife having a concave surface substantially the same as the concave surface in the rotary carrier and disposed an incremental distance away from the rotary carrier at least equal to the thickness of the peel and albedo layer of the fruit segment, the severing knife being oriented so as to have a substantial vertical component whereby the pulp will fall from the severing knife by the action of gravity.
