An air wash abrasive particle separator apparatus which separates contaminants from previously-used abrasive particles contained in a contaminated abrasive particle mixture such that the abrasive particles may be re-used multiple times, the apparatus being in combination a contaminated abrasive particle mixture delivery device, an accumulator hopper assembly, a volume sensing device, an automatic flow control valve, a separator assembly and an air transfer device.

A device for classifying a material mixture of multiple materials has a first transport unit into which the material mixture to be classified is deposited by a supply device. A second transport unit is arranged downstream. A first chute is provided between the first and second transport, via which a first material with a first fluid resistance can be separated from the material mixture. At least one third transport unit is arranged downstream of the second transport unit, such that a transit route for the materials is formed between the second and third transport units. A second chute is provided between the second and third transport units, via which at least the second material with a second fluid resistance can be separated from the material mixture. The third transport unit is designed so that material can pass through and/or a fluid flow can pass through.

A debris removal system for an agricultural harvester may include an extractor having an extractor housing defining a central airflow channel for directing debris through the extractor from a central inlet to a central outlet. The extractor housing may further define an outer airflow channel surrounding the central airflow channel. The outer airflow channel may define a flow path between an outer housing inlet and an outer airflow outlet. Additionally, the extractor housing may include an internal divider wall extending between the central and outer airflow channels. Moreover, the system may include at least one flow-generating device provided in operative association with the housing. The flow-generating device(s) may be configured to generate an airflow directed through the outer airflow channel, wherein the airflow generates a negative pressure within the central airflow channel that draws the debris into the extractor housing via the central airflow inlet.

A aerodynamic particle separator for an Additive Manufacturing System (AMS) has an air supply device to entrain a mixed powder in an airstream flowing through a housing. Each particle in the mixed powder is imparted with a momentum dependent upon the particle weight and size. Utilizing this momentum characteristic, the heavier particles are capable of crossing streamlines of the airstream at a bend portion of the housing and the lighter particles generally stay within the streamlines. Utilizing this dynamic characteristic, the particles of specific weight ranges are collected through respective offtake holes in the housing and controllably fed to a spreader of the AMS.

A heavies removal device including a frame supporting a transporter, a perforated sheet, and an opposing weight. A plurality of upper arms pivotally connect the transporter with the frame and a matching number of lower arms pivotally connect the opposing weight to the frame. Air is directed through the perforated sheet. A drive assembly, including a motor and an eccentric bearing, drive the arms in an upward and forward fashion. As lamina is fed onto the infeed end of the perforated sheet, each forward stroke of the upper arms throws the lamina upward and forward toward the discharge end of the sheet. Vanes on the perforated sheet direct the air as needed to the forward of the sheet to achieve the desired transport. The heavies are transported to the discharge end of the device where they are removed and may afterward be sent through to the next phase of processing.

A method for fractionating a milled grain product into coarse and fine fractions includes providing a sieving apparatus with a bottom chamber divided from a top chamber by a sieve, an inlet port in the top chamber, a top chamber cover defined by a plurality of openings, and a first exit port in the bottom chamber, and applying vacuum suction to the sieving apparatus. The vacuum suction is configured to draw grain particles through the inlet port into the top chamber, generate substantially horizontal airflow in the top chamber via the inlet port; and generate substantially vertical airflow in the top chamber via the plurality of openings, wherein the substantially horizontal airflow and the substantially vertical airflow combine to generate turbulence which fluidizes the grain particles in the upper chamber and prevents blockage of the sieve; and drawing fine grain particles through the sieve and out of the bottom chamber via the first exit port under the vacuum suction and collecting a fine grain particle fraction.

The disclosure discloses stabilized rice aleurone and a preparation method, using the technology of classifying a rice aleurone layer by a tangential injection airflow impeller classifier combined with an ultrasonic vibrating screen for the first time, and simultaneously uses steam treatment coupled with thermal enzyme inactivation by drum drying as a stabilization method to prepare the stabilized rice aleurone for the first time. The drum drying equipment realizes the two purposes of enzyme inactivation and drying, and the method has the advantages of short process flow, simple equipment, high utilization rate, small floor space, low investment, low energy consumption and no pollution, and is suitable for industrial promotion. The stabilized rice aleurone has high nutritional value, is rich in functional ingredients, and can be used as a raw material for functional food development in industrial production and food applications.

An apparatus for separating a granular material from a conveying air stream (5) comprising a deflecting surface (2) for the laden conveying air stream (5) against which flow may take place substantially tangentially is described. In order to allow advantageous separation conditions, it is proposed that the deflecting surface (2) adjoins a guiding surface (3) curved in the opposite direction in the flow direction for a largely laminar flow separation.

An agricultural grain cleaner includes an inlet chute having an inlet end and an outlet end positioned below the inlet end. A crop distribution member is positioned adjacent the outlet end of the inlet chute. The crop distribution member includes a distribution disc rotatable relative to the inlet chute about a vertical central axis to impart a horizontal trajectory, away from the central axis, to crop material supplied to the distribution disc from the inlet chute. A fan is operable to generate an air stream from below the crop distribution member, across the horizontal trajectory, to an air-chaff outlet. A grain collection chute has an inlet to receive grain that is cleaned of chaff by the air stream. A tailings collection chute is positioned adjacent to the grain collection chute on a radially inner side thereof.

A separator having a housing, a feed cone and a rotatable dispersing plate, on the upper face of which dispersing blades which are distributed across the periphery of the dispersing plate are arranged. The feed cone is arranged on the housing at a distance from the dispersing plate. The precision of the separator is improved compared to conventional separators.
