A sieving method for separating insect pupae is described. The method may include causing an actuation system of a sieving apparatus to cycle between a first elevation and a second elevation to cyclically submerge a sieve surface of a sieving device in a liquid held within a basin so as to separate a population of insect pupae present in the sieving device with respect to size. The method may also include causing actuation of one or more valves to drain the liquid from the basin in order to retrieve a first part of the population of insect pupae. Corresponding computer-readable devices and systems that perform the sieving method are also described.

An extractor can be used to extract solvent-soluble molecules, such as aqueous or organic-soluble molecules, from solid material feedstock for downstream processing and recovery. In one configuration, the extractor is a percolation extractor having one or more extraction chambers each containing a screen supporting the solid materials as it is conveyed through the chamber, a fluid supply system delivering extraction fluid disposed above the solid material, and a fluid recovery system disposed below the solid materials for receiving the extraction fluid and solvent-soluble molecules contained therein. The extractor further includes a screen washing system disposed under the screen and supported against movement. The screen washing system includes a washing fluid intake and a plurality of outlet nozzles directed upward towards the screen. The screen washing system can keep the screen from plugging during operation, improving the extraction efficiency of the extractor.

A self-cleaning apparatus for sorting a mixture of materials is disclosed that comprises a material sorter and a gantry positioning system elevated above the material sorter. The gantry positioning system includes a longitudinal travel rail with a longitudinal travel rail carriage, a traverse travel rail connected to the longitudinal travel rail carriage running perpendicular to the longitudinal travel rail, with a traverse travel rail carriage, and a vertical travel rail connected to the vertical travel rail carriage running perpendicular to the traverse travel rail. A cutter and optionally, a picker, are connected to the vertical travel rail. The gantry positioning system can move the cutter and picker various directions to dislodge and remove material that may have accumulated on the sorter. Instead of a gantry positioning system, the apparatus may have a multi-axis arm.

A screen assembly includes a housing defining a material flow chamber and having an inlet end and an outlet end, and a stucco discharge opening being located in the chamber between the inlet end and the outlet end. An auger shaft is located in the housing for axial rotation and having at least one first helical flight arranged in a flight pattern oriented so that material engaging the first helical flight is conveyed from the inlet end to the outlet end. A screen surrounds the at least one first helical flight for common rotation and extends generally from the inlet end to the outlet end. At least one second helical flight is disposed on an exterior surface of the screen and is arranged in a flight pattern oriented so that material engaging the second helical flight is conveyed in a direction from the outlet end.
