Citrus peel oil extractor for whole fruit

Claim 2

Apparatus for extracting oil from the peel of whole citrus fruit, comprising in combination: a pair of parallel horizontal toothed rolls forming a bight between them for reception and support of whole citrus fruit, means for rotating said rolls in the same direction to spin the fruit, an axially extending stationary inclined wall adjacent one of said rolls, and an axially extending bar mounted to travel in an orbital path over said bight, in a plane generally parallel to the plane containing the axes of said rolls and at an elevation above said bight to engage fruit thereon, means for moving said bar in said orbital path whereby said bar will contact the fruit intermittently above the rolls to move the fruit out of the bight into contact and axially along said wall to re-enter the same bight at an axially spaced location.

Claim 3

The combination as set forth in claim 1, in which a stop means is disposed in the bight between the pair of rolls and positioned for engagement by at least the smaller citrus fruit, to prevent excessive tearing of the rind.
