A filter device for filtering particles from an air flow has an inlet channel through which the air to be cleaned flows, at least one filter element through which the air can flow and which is held replaceably in a flow channel, and an outlet channel through which the cleaned air flows. The filter device has an insertion chamber which can be closed by a door and from which a filter element can be fed to the flow channel, and an output chamber which can be closed by a closure element and into which a filter element can be fed from the flow channel. A cover is attachable to the filter element, which covers a filter cake on the filter element so that the unit of filter element and cover is removable from the output chamber together.

A horizontal axis rotary separation apparatus is deployed in a process for separating resinous trichomes rich in flavoring, aromatic and/or medicinal components produced in plant trichome glands from unwanted plant matter. The process physically separates resin rich beads at the trichome gland head from extraneous plant matter by one or move separation sieves. The sieves are provided in or as a casing over a rigid frame member. The sieves are mesh fabric bags or screen that are easily opened and replenished in a batch operating mode, and are removable from the frame for cleaning and maintenance. Other aspects of the invention include processes that improve process efficiency and speed, and yield products of superior quality.

A rotating coalescer having an ejected coalesced liquid separating device is described. The separating device prevents re-entrainment of liquid into a stream of filtered gas. The rotating coalescer includes a rotating filter element or coalescing cone stack positioned within a rotating coalescer housing. The outer surface of the rotating filter element or the outlet of the coalescing cone stack is displaced from the inner surface of the rotating coalescer housing. The gap between the rotating filter element or the coalescing cone stack and the rotating coalescer housing allows for ejected coalesced liquid, such as oil, to accumulate on the inner surface of the rotating coalescer housing for drainage and allows for filtered gas, such as air, to exit through a clean gas outlet of the rotating coalescer housing.

A blow-by gas filtration assembly has an axis and includes an assembly body including a filtration chamber, an inlet mouth for filtering the blow-by gases, and an outlet mouth for the filtered blow-by gases. A filter group includes a central cavity radially crossed by blow-by gases. An electric drive operatively connects to the filter group to command rotation about the axis and filtration, and includes an electric motor including a stator and rotor. An axial shaft includes a filter portion mounting the filter group, a command portion mounting the rotor, and a support portion axially between the filter and command portions. A support bearing radially engages the support portion and the assembly body. The filter assembly screwably engages the filter group and filter portion, by respective filter and shaft threads so the filter group screws to the shaft until the support bearing is axially engaged.

A screening device and a self-propelled harvester with a screening device is disclosed. The screening device includes at least one suction nozzle that has an elongated hollow body with at least one suction opening which extends sectionally in the longitudinal direction and transverse direction of the hollow body, and is connected by at least one air duct in the interior of the hollow body to a connection arranged in the hollow body for connecting to a vacuum source. The suction opening is positioned facing a screen of the screening device. The air duct has a cross-sectional shape that increases in the vertical direction toward the connection starting from an outer end of the suction nozzle. An inner contour facing the suction opening of the air duct has a contour that substantially corresponds to an airfoil.
