Apparatus for extracting oil from the rind of whole citrus fruit

摘要

Horizontal rolls define troughs between them for reception and support of whole citrus fruit, each roll including a plurality of thin metal rings mounted in axially spaced relationship, each ring having a continuous series of pointed teeth on its periphery, and each ring being inclined to its rotary axis whereby rotary movement of the rings causes wobble movement of the disk peripheries so that penetration of the teeth is substantially uniform over the entire outer surface of each fruit. The rolls are turned in the same direction, each successive roll in a series turning at a slower speed. Washers are positioned between each pair of toothed rings and are free to move radially to prevent buildup of seeds, buttons, pieces of peel or other foreign matter on the toothed rings.
