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.

An ergonomic handheld citrus press allowing the use of closed fists and large force of the arms for comfortable and efficient operation, as opposed to the use of open fist and small force in conventional presses.

The ergonomic press is comprised of a first and a second elongated member hinged together at one end. The first member has a concave part with straining holes and the second member has a smaller convex part near the hinge. A first handle extends from the concave part and a second handle extends from the convex part at the opposite side of the hinge.

The first and second member may be rotated toward each other such that the concave part receives the convex part. In closed condition of the press, the handles are parallel and spaced apart by about 5 cm.

The user places a cut half of a citrus such as lemon in the concave part, holds the first handle in one fist and the second handle in another fist, and closes the press against the lemon. The lemon is squeezed between the concave and convex parts and its juice drips out of the straining holes. The distance between the handles provides space for the fists for full closure of the press and comfortable and efficient squeezing of the lemon.

A vending machine having integrated orange juice squeezing, filling, bottling and media, including a box, an opening-closing door, an adjustable supporting base, a rotary material basket, a transportation guide apparatus, a juicer, an electric control valve, a filling container, a waste residue guide apparatus, a waste residue collection bucket, a high-pressure air pump, an air storage tank, a bottle, a bottle container, a bottle transportation mechanism, a bottle guide apparatus, a bottling transportation production-line, a rotary product-output apparatus, a spray water pump, a spray control electromagnetic valve, a finished product aisle, a spray water storage tank, a waste-liquid recovery water tank, a refrigeration-insulation system, a stable voltage power supply, a system control apparatus, an LED light and an ultraviolet germicidal light.

Automatic juicer machine, comprising a fruit squeezing unit with two male drums and two female drums with synchronised rotary movement, the squeezing unit being fixed to a rear frame, wherein the frame comprises a photoelectric sensor located between the upper edge of the female drum that is fed with fruit and the upper edge of the frame, closer to the upper edge of the female drum that is fed with fruit than the upper edge of the frame.

A fruit press has shafts which are mounted in a frame for two pressing rollers, which can be driven in opposite directions, and for two ram heads, which are provided below the pressing rollers and form pressing rams that interact with pressing recesses of the pressing rollers. The fruit press has a blade, which is displaceable in a blade guide between the pressing rollers. The pressing rollers and the ram heads, which can be removed from their respective shafts, are held between a rear wall and a front mount of a handling unit detachably fastened to the frame. To achieve advantageous design conditions, the pressing rollers and the ram heads, which are supported axially on the front mount, are detachably held between bearing projections of the rear wall and receptacles in the region of the front mount.

The patent relates to a squeezing machine comprising a juice extraction unit housed in a casing and incorporating elements for an automated sanitization of the juice extraction unit and of the environment in which the squeezing occurs, the juice is stored and served, and method for sanitising a squeezing machine.

An improved hand operated citrus press is provided in direct operational combination with a liquid drinking vessel. The citrus press is provided removably connected to, and in fluid communication with, the liquid drinking vessel. The fluid contained within the drinking vessel can be infused with the essences from the ground or comminuted fruit from the citrus press. The fluid communication between the comminuting volume of the citrus press grinder assembly and the container allows these all natural ingredients to steep directly with the beverage, creating refreshingly flavored drinks that are as rich and natural in nutrients as its ingredients.

An improved lemon squeezer comprises of a stand. The stand has a footprint that extends outward from the front of the stand. The stand defines a top and a bottom plate. The bottom plate is a plate that defines a plurality of depression and it defines a fluid receiving a cavity. The top plate defines a plurality of protrusions that insert within the bottom plates depressions when the plates are squeezed together via a lever mechanism that is attached to the top plate.

An improved citrus juice finisher is provided for producing thin juice. A first aspect is an improved screen design with small perforations having diverging walls in the direction of juice moving through the screen to prevent blinding of the screen by entrained particles. A second aspect is a juice modulator which pulverizes the entrained particles to a desired size and viscosity. A third aspect is an improved multi-vane finisher with increased yield and capacity.
