A two stage system for extraction of oil from whole citrus fruit is provided. The first stage is known in the art and includes a first plurality of toothed rollers which convey citrus as the teeth penetrate and rupture oil glands. The oil passes into a first water pan. A novel second stage uses a second plurality of toothed rollers to continue the penetration and rupturing of oil glands. The second plurality of rollers are positioned in an isolated second pan to partially submerge the citrus. A middle phase liquor with extremely low oil concentration is transferred into said second pan to initiate desorption of oil from the citrus. The desorption technique in one embodiment increases yield by 4% or more. This technique is expected to increase yield even more as the recovery by the first stage is reduced.
A two stage method for extraction of oil from the peel of whole citrus fruit, including primary and secondary extraction wherein the primary extraction of oil is obtained by causing said fruit to be conveyed across a first plurality of generally parallel toothed rollers in a direction perpendicular to the axes of rotation of said toothed rollers, wherein said toothed rollers have projections which penetrate the oil glands in the peel of said citrus to cause oil to drain downwardly from said citrus, wherein said oil is collected in a first pan of water to form an emulsion of citrus oil and water, and wherein said emulsion is then transferred to a centrifuge or other separator to remove and collect most of the oil from said emulsion, wherein said emulsion after oil separation is a middle phase liquor, and
A two stage apparatus for automatic extraction of oil from the peel of whole citrus fruit, comprising:
