Abstract: 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.

Abstract: A washer for a fruit processing machine includes a rotary nozzle paddlewheel gear mounted in a nozzle housing. The rotary nozzle paddlewheel gear meshes with combination gears which in turn mesh with a wash nozzle. Fluid pumped into the housing drives the gears and blows out through the rotary wash nozzle creating a spray pattern. As the rotary wash nozzle completes a revolution, a hemispherical or larger region is sprayed by the fluid, cleaning the equipment to be washed.

Abstract: A rotary fruit and juice extractor has pairs of holding cups pivotally mounted to a rotating frame. A rotatable reamer is associated with each cup. Cams pivot the cups from a fruit loading position, to a fruit slicing position and then to a reaming position as the frame rotates. Reamer cams drive the reamers into and out of the fruit halves held within the cups as the frame rotates.

Abstract: A fruit sizing apparatus includes a guideway having an inclined surface extending from a base to a peak with a first channel adjacent to the peak and a second channel adjacent to the base. First and second endless moving belts are supported in part by the first and second channels respectively. The first and second belts are driven at different speeds. A roller is spaced apart from the guideway and rotates in a direction tending to cause fruit to roll up the incline surface.

Abstract: A centrifugal finisher and method of its operation are disclosed for separating finished juice from an initial juice including substantial solids or for separating finished fluid from any slurry including substantial solids, the slurry being introduced into one end of a cylindrical screen driven in rotation for centrifugally urging the slurry against the screen and causing a fluid component to pass through the screen. Wiper paddles are arranged on a support drum for rotation in wiping contact with the screen and for limited movement relative to the screen for continuously moving solid material from the slurry toward an outlet axial end of the screen.

Abstract: A method and apparatus is disclosed for enhanced juice extraction from citrus fruit, the apparatus being of a type including an annular carousel with circumferentially arranged cups, a rotary reamer assembly smaller than the carousel having circumferentially arranged reamer elements arranged in tangential relation with the cups of the carousel at a maximum reaming position, a device for supplying halves of citrus fruit to the cups for processing and for subsequently removing reamed citrus skins, drive dogs being mounted on the reamer assembly between each adjacent pair of reamer elements and shaped so that they radially and circumferentially engage and position the cups in precise alignment with the reamer elements at the maximum reaming position in order to assure optimum extraction of juice from the citrus fruit.

Abstract: Peel oil is extracted from whole citrus fruit by means of a plurality of parallel horizontal toothed rolls. The toothed rolls define bights between them for reception and support of whole citrus fruit. Each roll comprises a shaft carrying a series of thin parallel rings each ring having a continuous series of pointed teeth on its periphery. A motor rotates the rolls in the same direction at different speeds. Water spray nozzles are spaced above the rolls to deliver relatively coarse sprays against the outer surface of each whole citrus fruit to carry away peel oil produced by the pointed teeth of the rings.
