A system 400 for obtaining a substance from a commodity has a first apparatus 420 with first 422 and second 424 openings, a device 426 for moving the commodity through the first apparatus, and at least one blade 428 for shearing the commodity. The at least one blade 428 is positioned between the first opening 422 and the second opening 424. A second apparatus 440 has a first opening 442 and a second opening 444, with the first opening 442 being fluidly connected to the second opening 424 of the first apparatus 420. The second apparatus 440 includes a device 446 for moving the sheared commodity from the second apparatus first opening 442 to the second opening 444. A third apparatus 460 obtains the substance from the sheared commodity, including a separator 460 having a first opening 462 fluidly connected to the second opening 444 of the second apparatus 440.

An oil extractor that includes: a main body housing; a motor; a feed hopper detachably coupled to the upper end of the main body housing to feed grain; a shell that communicates with the lower end of the feed hopper to receive the grain and is detachably coupled to one side of the main body housing; a screw shaft inserted into the shell and having an end portion that passes through one side of the main body housing and is coupled to the motor; a fastening means for detachably coupling the shell to the main body housing; and a shell cover surrounding the shell. The shell cover has a groove formed on its lower portion for receiving the shell and is supported by the main body housing and moves between a first position at which the shell is covered and a second position at which the shell is exposed.

The present invention concerns a method for preparing dehydrated avocados, a method for preparing an unsaponifiable-rich avocado oil, a method for preparing an avocado cake rich in sugars and proteins, and a method for preparing an unsaponifiable fraction; these methods all comprising a step of drying avocado slices by means of microwaves until dehydrated avocados are obtained having residual moisture less than or equal to 5%; during this step, the water evaporated under the action of the microwaves being eliminated by a warm air stream with a temperature less than or equal to 80° C. and/or by air extraction.

An oil recovery extraction system includes a feeding and weighing system to weigh fruit and feed the fruit to an oil recovery extractor; extraction rollers that perforate a surface of the fruit to allow oil to flow out from the surface into the emulsion extractor reservoir; and a fruit washing system to spray the fruit with potable water to wash oil remaining on the fruit after the fruit has left the oil emulsion extractor reservoir; wherein an oil-water emulsion from the oil emulsion extractor and an oil-water emulsion from the fruit washing system are combined into an oil-emulsion; and a process control system to measure and control operational parameters of the machine, including calculating a setpoint feed flow of the fruit, then measuring and controlling the feed flow of fruit based on the setpoint, and further calculating a setpoint flow of potable water, heavy phase, then measuring and controlling the flows.

The present invention relates to a method and system of extracting an oil from an oil-containing raw material comprising the steps of providing a non-crushed oil-containing raw material, and treating the non-crushed oil-containing raw material. The treatment is performed by exposing the oil-containing raw material to vacuum, wherein the vacuum defines an absolute pressure of between 1 mm Hg and 150 mm Hg, and a temperature of between 0° C. and 45° C., and by subjecting the oil-containing raw material to crushing, simultaneously and/or subsequently to the step of exposing the oil-containing raw material to the vacuum, to provide a treated oil-containing raw material. By the method and system, high yield of oil with high quality can be obtained.
