A fully automatic peanuts peeling robot for seeds retention and a method using the same are provided. The robot includes a processing mechanism, a feeding mechanism and a screening mechanism. The processing mechanism includes an aluminum profile support bracket, a bracket assembly, a conveyor belt device, and a conversion device, a sensor device and a cut-off device; the aluminum profile support bracket is fixedly connected to the bracket assembly; the bracket assembly includes a first bracket assembly, a second bracket assembly, and a third bracket assembly; and the aluminum profile support bracket is fixedly connected to the conveyor belt device; the conveyor belt device includes a first conveyor belt assembly, a second conveyor belt assembly, and a third conveyor belt assembly; the conveyor belt device is fixedly connected to the conversion device.

A continuous sieving apparatus is described. The continuous sieving apparatus includes an inclined sieve surface attached to a wall. The inclined sieve surface is inclined with respect to a horizontal axis for pupae to continuously flow across down the incline. A set of openings is formed in the sieve surface so as to define a set of pathways extending through the sieve surface. The set of opening are defined by a length dimension that is greater than a width dimension. When the inclined sieve surface is submerged in a liquid, a first pupa having a first cephalothorax width that is less than the width dimension is free to move through any one of the set of openings, and a second pupa having a second cephalothorax width that is greater than the width dimension is prevented from moving through the set of openings.

A sieving device is described. The sieving device includes an adjustable sieve surface that includes a first sieve surface and a second sieve surface. Openings are formed in each of the first sieve surface and the second sieve surface so as to define a shared pathways extending through the adjustable sieve surface. The shared pathways are defined by a length dimension that is greater than a width dimension. The width dimension can correspond to a cephalothorax width of an insect.

A male population of mosquito pupae sorted according to a sorting method is described. The sorting method may include adding a mixed population of mosquito pupae into an interior volume of a sieving container including base defining a set of openings enabling movement of mosquito pupae from the interior volume through the set of openings. The mixed population of mosquito pupae may include male mosquito pupae and female mosquito pupae. The method may also include adding a volume of aqueous solution to the interior volume. The method may also include removing a portion of the male pupae from the mixed population of mosquito pupae to by performing a sieving action that causes the portion of the male pupae and a portion of the volume of water to pass from the interior volume through the set of openings. The method may also include capturing the portion of the male pupae as the male population of mosquito pupae after the portion of the male pupae has passed through the set of openings.

A screen apparatus for screening granulate, in particular moist and/or dry granulate, having a screen housing having a base, a cover and a side wall, an inlet for the granulate arranged on the screen housing, an outlet for the screened granulate arranged on the screen housing, a screen arranged in the screen housing and an inlet for transfer air. The outlet for the screened granulate, which is arranged on the screen housing is arranged on the side wall of the screen housing.

An object-sorting apparatus includes a housing that extends from a top end to a bottom end, at least one vibration element, and a plurality of stages arranged in a vertical sequence in the housing between the top end and the bottom end. At least one of the stages includes a sorting base that at least partially defines a floor of the at least one stage. The sorting base is coupled to the at least one vibration element, and is configured to receive thereon a mixture of objects having different sizes, including a target size associated with the at least one stage. The stage also includes apertures defined in and extending through the sorting base and into flow communication with a next lower stage. The apertures are sized to receive therethrough, from the mixture, objects having a size smaller than the target size associated with the at least one stage.

A stem screening and conditioning device includes a roller, a thermal insulation cover, a spiral feeding device, a compressed-air cleaning device, a steam tube, a discharge hole, and a waste hole. A stem screening and conditioning method for the stem screening and conditioning device is also provided. The present disclosure realizes the complete separation of normal-size and undersized stems under the premise of full moisture absorption, thereby improving the refinement and homogenization level of stem conditioning.

A screen cloth for use in a screening device for screening out oversize objects, including oil sands lumps and rocks present in an oil sands slurry is provided, comprising at least one screen segment having a top surface and having a plurality of openings therein; and a plurality of anti-wear tiles attached to the top surface of the at least one screen segment by brazing; whereby each anti-wear tile is separated from an adjacent anti-wear tile by a gap that is about 0.5 mm or less such that a brazing material used to attach the anti-wear tiles to the at least one support structure fills the gap between each anti-wear tile through capillary action thereby connecting each anti-wear tile to its adjacent anti-wear tile.

A screening apparatus includes a plurality of spaced apart parallel beams and a plurality of screen panels mounted to the beams to form a planar screening surface. The panels are mounted to the beams by fixing members that extend in the longitudinal direction of the beams and that engage side edges of the panels. The fixing members have a pair of upstanding, longitudinal rails that are spaced apart to define a longitudinal gap between them and the panels are mounted to the beams by engagement between side edges of each panel with a rail of a fixing member. The side edges of each panel include an overhang that overlies an upper end of each rail and that extends into the gap between the rails. The rails and the overhang include locating gaps to receive a locking member to locate panels relative to the fixing members.

Screening members, screening assemblies, methods for fabricating screening members and assemblies and methods for screening materials are provided for vibratory screening machines that incorporate the use of injection molded materials. Use of injection molded screen elements provide, inter alia, for: varying screening surface configurations; fast and relatively simple screen assembly fabrication; and a combination of outstanding screen assembly mechanical and electrical properties, including toughness, wear and chemical resistance. Embodiments of the present invention use a thermoplastic injection molded material.
