A dedusting apparatus removes dust and debris from particulate material flowing over the surface of a wash deck formed with steps and incorporating an air knife engaging the flow of particulate material as the material drops from one wash deck level to another. An ionizing wire is placed at each step on the wash deck so that the air knife blows negative ions from the ionizing wire into the particulate material falling off the step onto the level of wash deck below the ionizing wire. The wash deck is formed with openings to allow air to blow through the wash deck surface and remove dust and debris from the flow of particulate material. The wash deck can be constructed from modules supported on one another in a manner to present an overhang at each step. The wash deck can be formed from a flat pattern as a unitary bent structure.

A particulate collector includes a housing having an air intake port and an exhaust port and a flow channel, in the housing, connecting the two ports, a fan rotatable about an R-axis to generate airflow in the flow channel, a spray unit that sprays first liquid into a first portion in the flow channel, a first filter located between the first portion and the exhaust port and supported rotatably about the R-axis, a power source that rotates the first filter, a first collection port for collecting a first particulate covered with liquid contained in the first liquid from the flow channel through a second portion in the first filter, and a second collection port for collecting a second particulate covered with liquid contained in the first liquid from the flow channel through a third portion in the first filter. The second portion is located between the first and third portions.

A classifier for separating particles is provided. The classifier includes a rotor having a direction of rotation defined by a rotational axis of the rotor, and a plurality of blades disposed on the rotor around the rotational axis. At least one blade of the plurality has a swept orientation in the direction of rotation. The at least one blade is arranged to contact and direct the particles away from the classifier and thereby restrict the particles from concentrating in areas adjacent to the classifier.

A device for separating seeds from other plant material may include a front wall, a rear wall, two side walls extending between the front and rear walls, and a bottom wall. The device may include other internal walls to create an air flow path from a first one of the side walls to a second one of the side walls. A fan can induce an air flow along the air flow path. Raw plant material can be fed into the device and allowed to fall through the air flow path, and the air flow can separate seeds in the raw plant material from other plant material.
