METHOD AND APPARATUS FOR INCREASED RECOVERY OF OIL FROM LEMONS AND OTHER CITRUS FRUIT USING DESORPTION

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 se...

Zusammenfassung:	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.
